In the model, managers issue a combination ofdebt and equity to finance investment by weighing the trade-off betweenagency problems and risk sharing. During contractions, leveragedmanagers receive a relatively small share of wealth, resulting in arelative increase in household demand for securities. Securities marketsclear as managers that are not up against their borrowing constraintsincrease leverage while satisfying the agency condition that theymaintain a large enough portion of their firm&rsquo;s equity.

Under natural conditions, prices are lowerand illiquidity discounts higher when counterparties are harder to find,when sellers have less bargaining power, when the fraction of qualifiedowners is smaller, or when risk aversion, volatility, or hedging demandare larger. If agents face risk limits, then higher volatility leads togreater difficulty locating unconstrained buyers, resulting in lowerprices. Information can fail to be revealed through trading when searchis difficult. We discuss a variety of financial applications andtestable implications.

We develop andestimate an empirical model based on the ICAPM to investigate thisrelation. Our primary innovation is to model and identify empiricallythe two components of expected returns &ndash;the risk component and thecomponent due to the desire to hedge changes in investmentopportunities. We also explicitly model the effect of shocks to expectedreturns on ex post returns and use implied volatility from added optionsto increase estimation efficiency. As a result, the coefficient ofrelative risk aversion is estimated more precisely, and we find it to bepositive and reasonable in magnitude. Although volatility risk ispriced, as theory dictates, it contributes only a small amount to thetime-variation in expected returns. Expected returns are drivenprimarily by the desire to hedge changes in investment opportunities.It is the omission of this hedge component that is responsible for thecontradictory and counter-intuitive results in the existing literature.

The first focuseson the multiplier of the irreversible constraint and is applied to thesituation where preferences are CES and the production function isCobb-Douglas.

Each sectorproduces one good, and each firm has a linear production technology andfaces a quadratic capital adjustment cost. The model contains a standardintertemporal capital asset pricing theory of consumption and portfoliodemands with dynamically complete and frictionless markets and astandard q-theory of investment under uncertainty. We show that theequilibrium stochastic investment opportunity set is driven by therelative shares of firms' nominal capital stocks, and the equilibriumdynamics of the state vector is driven by firms' relative investmentintensities. Key implications of the model includes (i) the expectedequity returns are endogenously predictable both over time and in thecross-section; and (ii) the &quot;value anomaly&quot; arises in arational expectations equilibrium due to a negative (positive) hedgingdemand for value (growth) stocks against the risk of cross-sectionaldispersion of firms' nominal capital stocks.

On the financial side, IPOs respond more elastically toTobin&rsquo;s Q than seasoned offerings of securities. The explanationseems to be that a high aggregate Q raises new firms&rsquo; desiredinvestment much more than it raises the desired investment ofincumbents. For the period from 1955 to 2001, the Q-elasticity of IPOsis about 1.2, and the elasticity of new-firms&rsquo; investment is about0.7. These are about 20 times more than is usual in Q regressions. Onthe other hand, the Q-elasticity of seasoned offerings is actuallynegative (-0.05), and the elasticity of incumbents&rsquo; investment is0.04. Though not statistically significant, the average of theseestimates is even smaller than is usual.

Indeed, the innovation may, at first, reduce themarket's value because some firms --- usually large or old --- willcling to old technologies that have lost their momentum. This paperargues that (a) the market declined in the late 1960s because it feltthat the old technologies either had lost their momentum or would giveway to IT, and that (b) IT innovators boosted the stock market's valueonly in the 1980s. If the stock market provides a forecast of futureevents, then the recent dramatic upswing represents a rosy estimateabout growth in future profits for the economy. This translates into aforecast of higher output and productivity growth, holding other thingsequal (such as capital's share of income).

Because of information costs, a class of investors is assumed topossess incomplete information, which suffices to implement only aparticular trading strategy. The IRH is mapped into correspondingportfolio restrictions that bind a subset of agents. The model isformulated in continuous time, and detailed characterization ofequilibrium quantities is provided. The model implies that, all elseequal, a risk premium on a less visible stock need not be higher thanthat on a more visible stock with a lower volatility -- contrary toresults derived in a static mean-variance setting. An empirical analysissuggests that a consumption-based capital asset pricing model (CCAPM)augmented by the IRH is a more realistic model than the traditionalCCAPM for explaining the cross-sectional variation in unconditionalexpected equity returns.

This procyclicality in borrowing capacity isat the heart of the mechanism underlying the financial accelerator. Ourempirical strategy uses international variation in maximum LTV ratios toshow that housing prices as well as demand for new mortgages are moresensitive to income shocks in countries with higher LTV ratios,consistent with the dynamics of a collateral-based financial acceleratorin household spending. We also find that the empirical relationshipbetween maximum LTV ratios and income sensitivities is stronger incountries where housing prices are low relative to household income.Because collateral constraints are less likely to bind when housing ismore expensive (an income constraint may bind instead), these latterresults further suggest that a collateral-based accelerator is indeedbehind the observed cross-country differences in income sensitivities.

Eventoday, after the market declines since 2000, they remain well abovehistorical norms. Why? We consider one particular explanation: a fall inmacroeconomic risk, or the volatility of the aggregate economy. Weestimate a two-state regime switching model for the volatility and meanof consumption growth, and find evidence of a shift to substantiallylower consumption volatility at the beginning of the 1990s. We then showthat there is a strong and statistically robust correlation between lowmacroeconomic volatility and high asset prices: the estimated posteriorprobability of being in a low volatility state explains 30 to 60 percentof the post-war variation in the log price-dividend ratio, depending onthe measure of consumption analyzed. Next, we study a rational assetpricing model with regime switches in both the mean and standarddeviation of consumption growth, where the probabilities of a regimechange are calibrated to match estimates from post-war data. Plausibleparameterizations of the model are found to account for a significantfraction of the run-up in asset valuation ratios observed in the late 1990s.

From 1967 to 1996 cross-sectionaldispersion of earnings increased more than wage dispersion, due to arise in the correlation between wages and hours worked. Over the sameperiod, inequality in hours worked remained roughly constant, and thedispersion in consumption and wealth increased only modestly. Using datafrom the PSID, we decompose the observed rise in wage inequality intochanges in the variance of permanent, persistent and transitory shocks.With this changing wage process as the only primitive, we show that acalibrated overlapping-generations model with incomplete markets canaccount for these trends in cross-sectional US data. We also investigatethe welfare costs of the rise in wage inequality: the ex-ante loss isequivalent to a five percent decline in lifetime income for theworst-affected cohorts.

For the case of defaultablesecurities we explore the relative fits to historical yield spreads.

Previous work on bondallocation requires a specific model for equities, the term structure,and the investor's utility function.

The structural modelis estimated using the conditional market variance implied by S&amp;P100 index option prices. Relative risk aversion is precisely identifiedand is found to be positive, with point estimates ranging from 3.06 to4.01. However, the implied volatility data only spans the periodNovember 1983 to May 1995. As a robustness check, the structural modelis also examined with postwar monthly data, in which the conditionalmarket variance is estimated. We again find a positive and significantrisk-return relation and get similar point estimates for relative riskaversion. Additionally, we document some facts about stock marketreturn. First, stock price movements are primarily driven by changes ininvestment opportunities, not by changes in market volatility. Second,there is some evidence of a leverage effect. Third, relative riskaversion is quite stable over time.

The implied dynamics of term premiums and volatilitiesare complex and interesting. Business cycle turning points arecharacterized by high volatility and strongly time-varying termpremiums. These implications are then investigated using data on bondreturns. Nonparametric estimation results are broadly consistent withthe model. Using the slope of the term structure as a conditioningvariable, we can identify periods with negative term premiums andvolatile returns.

The basis for the analysis is the free entrycondition. This yields a relationship between the resources devoted toR&amp;D and the growth rate of technology. Since innovators are small,this relationship is not directly affected by the size of the R&amp;Dexternalities, the presence of scale effects or diminishing returns inR&amp;D after controlling for the growth rate of output and the interestrate. The resulting contribution of R&amp;D to productivity growth inthe US is smaller than three to five tenths of one percentage point.Interestingly, this constitutes an upper bound for the case whereinnovators internalize the consequences of their R&amp;D investments onthe cost of conducting future innovations. From a normative perspective,this analysis implies that, if the innovation technology takes the formassumed in the literature, the actual US R&amp;D intensity may be thesocially optimal.

If agents default on theirdebt, they are banned from future intertemporal trade, but retain theirprivate (labor) endowments which are subject to income taxation. Weimpose individual rationality constraints on agents guaranteeing nodefault in equilibrium and we solve for efficient consumptiondistribution across agents. A change in the tax system changes theseverity of punishment from default. We demonstrate that a change to amore redistributive tax system leads to a restriction of the set ofcontracts that are individually rational and that this restriction leadsto a limitation of possible risk sharing via private contracts. Thewelfare consequences of a change in the tax system depend on therelative magnitudes of increased risk sharing forced by the new taxsystem and the reduced risk sharing in private insurance markets. Wequantitatively address this issue by calibrating an artificial economyto US income and tax data. We show that for a plausible selection of thestructural parameters of our model, the change to a more redistributivetax system leads to less risk sharing among individuals and, hence,lower ex-ante welfare.

The state space is discrete andprice-consumption ratios are obtained portfolio by portfolio simply byinverting an economy-wide matrix and multiplying this matrix by aportfolio-specific vector. The economy-wide matrix has thedimensionality of the state space. The paper calibrates cash flowpredictability to the data using the consumption-wealth fraction (cay)of Lettau and Ludvigson (2000a) and dividend yield (div) as statevariables. Annual cash flow processes are calibrated for three stockportfolios and for the aggregate consumption stream. The economy'srepresentative agent possesses a relative risk aversion coefficient ofeither 5 or 10. When cash flow predictability is calibrated to the datausing cay as the predictor and risk aversion is 5, equilibrium excessreturns on the four assets are more volatile, more correlated with eachother, and have higher means than in the equivalent economy with i.i.d.cash flows. Further, the conditional second moments for returns and thecontemporaneous state variable are found to be highly state-dependent.The paper finds much smaller excess return predictability using cay inthe calibrated economy than in the data, though the relation is positivein both. Conditional Sharpe ratios are virtually invariant to state.While the representative agent's optimal portfolio is not verystate-dependent, her hedging demands are quite large and her optimalportfolio is not minimum-variance. For example, her single-periodallocation to the four risky assets is about 75% of the portfolio whileher infinite-horizon allocation is 100%. The implication is that theconditional CAPM does not hold in the conditional economy with cay asthe state variable. However, the spread in CAPM abnormal returns acrossthe three book-to-market portfolios is an order of magnitude smaller inthe calibrated economies than in the data. The spread in the data in5.6% p.a. while the largest spread in the six calibrated economiesconsidered is only 0.6% p.a. Finally, the paper has importantimplications for partial equilibrium analyses of dynamic portfolio choice.

Inparticular, the paper assesses the impact of return predictability onportfolio choice for a multi-period investor with a coefficient ofrelative risk aversion of 4. Compared to the investor&rsquo;s allocationin her last period, return predictability with dividend yield causes theinvestor early in life to tilt her risky-asset portfolio away from highbook-to-market stocks and away from small stocks. These results areexplained using Merton&rsquo;s (1973) characterization of portfolioallocation by a multiperiod investor in a continuous time setting.Abnormal returns relative to the investor&rsquo;s optimal early-lifeportfolio are also calculated. These abnormal returns are found toexhibit the same cross-sectional patterns as abnormal returns calculatedrelative to the market portfolio: higher for small than large firms, andhigher for high than low book-to-market firms. Thus, hedging demand maybe a partial explanation for the high expected returns documentedempirically for small firms and high book-to-market firms. However, evenwith this hedging demand, the investor wants to short-sell the lowbook-to market portfolio to hold the high book-to-market portfolio. Theutility costs of using a value-weighted equity index or of ignoringpredictability are also calculated. An investor using a value-weightedequity index would give up a much larger fraction of her wealth to haveaccess to book-to-market portfolios than size portfolios. Finally, whilean investor would give up a much larger fraction of her wealth to haveaccess to dividend yield information than term spread information, termspread does have incremental benefits over and above just using dividendyield alone.

By examining political electioncycles, we find that eight out of nine of the recent financial criseshappened during periods of political election and transition. Using acombination of probit and switching regression analysis, we find thatthere is a significant relationship between political election andfinancial crisis after controlling for differences in economic andfinancial conditions. We observe increased market volatility duringpolitical election and transition periods. Moreover, we have someevidence that political risk is more important in explaining financialcrisis than market contagion. Our results suggest that politicaluncertainty could be a major contributing factor to financial crisis.Thus, politics does matter in emerging markets. Since the odds offinancial crisis tend to be much larger during the political electionperiods, institutional investors should take that into account whenmaking emerging market investment during those time periods.

The aggregatelabor income as a function of recent history of aggregate outputs isdetermined by the prevailing mode of income distribution. I focus on amodern capitalist economy in which the income distribution is notdictated by the capitalists (as in the formative years of capitalismwhich was the subject of inquiry by Adam Smith, David Ricardo, and KarlMax), but rather is determined by the economic and political consensusreached between the capitalists and workers through a legal andpolitical framework featuring strong labor unions, anti-trust laws, andprogressive tax codes. Three main implications for the macro-economyare presented. First, my theory endogenizes completely thethree-equation Klein model of consumption function, savings function,and the wage demand function. Second, I show that cyclic behavior isdriven entirely by the assumed form of income distribution. Productionand labor income shocks do not drive, but help sustain the cyclicbehavior by preventing the economy from converging to the steady statemean. Third, I show that the Marxian doctrine that the &quot;rate ofsurplus value&quot; remains constant and the &quot;organic compositionof capital&quot; keeps rising is inconsistent with the predictions of mymodel, and the difference is traced to the different assumptions onincome distribution, and leads to different conclusions on the stabilityof capitalist economies. By assuming that capital markets clear inequilibrium, I determine the risk premium for both production and laborincome risks, and consequently asset returns and the value of humancapital - all endogenously. A special case of the model isobservationally equivalent to the stochastic habit formation model ofDai (2000), and thus inherits its ability to simultaneously explain theequity premium puzzle, riskless rate puzzle, and the expectationspuzzle. In general, the labor market need not clear, due to the onlyfriction in the model: the longevity of the labor contract.

Previous solutions either require approximations, numericalmethods, or the assumption that the investor does not consume over hislifetime. This paper breaks the impasse by assuming that markets arecomplete. The solution leads to a new understanding of hedging demandand the behavior of approximate log-linear solutions. The portfolioallocation takes the form of a weighted average and is shown to beanalogous to duration for coupon bonds. Through this analogy, the notionof investment horizon is extended to that of an investor who consumes atmultiple points in time.

Among threetwo-year sample periods for Major Market Index stocks, only a 1987-88sample results in an estimated jump component with low frequency andlarge size. Using Bayes' rule, we infer ex post jump probabilities foreach sample day. In contrast to an analogous univariate model for anindex return, the multivariate model captures information in thecross-section of returns. Leading financial news on the most likely jumpdays from the multivariate model is compared with news on a controlgroup of high index return days. Days with high jump probabilities underthe multivariate model contain systematically more news related to thedollar, trade deficits, and financing of the U. S. budget deficit. Thissuggest that the common jump component proxies for economic fundamentsrelated to this cluster of news events, and that the unexpectedly largeU.S. trade deficit news released on the Wednesday prior to the crashprovided an economic catalyst for the event.

We numerically solve the individual&rsquo;smultiperiod problem in the presence of transaction costs andpredictability. In particular, we characterize the investor&rsquo;soptimal portfolio choice with proportional and fixed transaction costs,and with return predictability similar to that observed for the U.S.stock market. We also perform some comparative statistics to betterunderstand the nature of the no-trade region with more than one riskyasset. Throughout our focus is on the case with two risky assets. Wealso perform some utility comparisons. The calibration exercise revealssome interesting results about the relative attractiveness of the threeequity portfolios calibrated. With proportional transaction costs andi.i.d. returns, we numerically find the rebalancing rule to be ano-trade region for the portfolio weights with rebalancing to theboundary. With zero correlation, the no-trade region is a rectangleirrespective of the investor&rsquo;s age. When the correlation of therisky assets is non-zero, the no-trade region becomes a parallelogram.With positive correlation, the parallelogram distorts the associatedrectangle in such a way as to take advantage of the associatedsubstitutability across the two assets that the positive correlationinduces. The converse is true for negative correlation. Turning to theallocations with return predictability, our numerical results stronglysuggest that it is the conditional return correlation that determinesthe nature of the distortion to the no-trade parallelogram. Irrespectiveof the investor&rsquo;s age, the distortion always mirrors the no-tradeparallelogram distortion that we find in the i.i.d. case for returncorrelation of the same sign. The no-trade region is always larger latein life than early in life. However, the difference in no-trade areabetween early and late in life is less pronounced when returns arepredictable, consistent with intuition that the benefits fromrebalancing today are more short-lived when returns are predictable thanin the i.i.d. case.

That is, periods ofstagnation are often associated with significant recessions, whilepersistent booms typically are either free of recessions or areinterrupted only by very modest downturns. In this paper we explore theidea of medium term cycles, which we define as reflecting the sum of thehigh and medium frequency variation in the data. We develop amethodology for identifying these kinds of fluctuations and then showthat a number of important macroeconomic time series exhibit significantmedium term cycles. The cycles feature strong procyclical movements inboth disembodied and embodied technological change, research &amp;development, and the efficiency of resource utilization. We then developa model to explain the medium term cycle that features both disembodiedand embodied endogenous technological change, along with countercyclicalmarkups and variable factor utilization. The model is able to generatemedium term fluctuations in output, technological change, and resourceutilization that resemble the data, with a non-technological shock asthe exogenous disturbance. In particular, the model offers a unifiedapproach to explaining both high and medium frequency variation inaggregate business activity.

Complementarity in informationacquisition can explain these anomalies. Because information has a highfixed cost of production, its equilibrium price is low when quantity ishigh. Investors all buy the same information because it has the lowestprice. By lowering risk, information raises the asset's price. Giventwo identical assets, investors herd: one price is higher becauseabundant information about that asset reduces its payoff risk.Transitions between low-information/low-asset-price andhigh-information/high-asset-price equilibria create price pathsresembling periodic frenzies. Using equity data and a new panel data setof news counts for 23 emerging markets, the results show that when assetmarket volatility increases, news coverage intensifies, and that morenews is correlated with higher asset prices and higher cross-marketprice dispersion.

Our explanation for thispattern rests on learning about productivity. When agents believeproductivity is high, they work, invest, and produce more. Moreproduction generates higher precision information. When the economypasses the peak of a productivity boom, precise estimates of theslowdown prompt quick, decisive reactions: Investment and labor fallsharply. At the end of a slump, low production yields noisy estimates ofthe recovery. The noise impedes learning, slows the recovery, and makesbooms more gradual than crashes. A calibrated model generates asymmetryin growth rates similar to macroeconomic aggregates. Fluctuations inagents&rsquo; forecast precision match observed countercyclicaldispersion in analysts&rsquo; macroeconomic forecasts. &ldquo;There is,however, another characteristic of what we call the trade cycle that ourexplanation must cover; namely, the phenomenon of the crisis - the factthat the substitution of a downward for an upward tendency often takesplace suddenly and violently, whereas there is, as a rule, no such sharpturning point when an upward is substituted for a downwardtendency.&rdquo; J.M.

An Empirical Investigation of Habit-Based Asset Pricing Models<br/><br/>Chen, Xiaohong; Ludvigson, Sydney C.<br/><br/>Abstract: A popular explanation of aggregate stock market behavior suggests thatassets are priced as if there were a representative investor whoseutility is a power function of the difference between aggregateconsumption and a &ldquo;habit&rdquo; level, where the habit is somefunction of lagged and (possibly) contemporaneous consumption. Buttheory does not provide precise guidelines about the parametricfunctional relationship between the habit and aggregate consumption.This makes for- mal estimation and testing challenging; at the sametime, it raises an empirical question about the functional form of thehabit that best explains asset pricing data. This paper studies theability of a general class of habit-based asset pricing models to matchthe conditional moment restrictions implied by asset pricing theory. Ourapproach is to treat the functional form of the habit as unknown, and toestimate it along with the rest of the model&rsquo;s finite dimensionalparameters. This semiparametric approach allows us to empiricallyevaluate a number of interesting hypotheses about the specification ofhabit-based asset pricing models. Using stationary quarterly data onconsumption growth, assets returns and instruments, our empiricalresults indicate that the estimated habit function is nonlinear, thehabit formation is internal, and the estimated time-preference parameterand the power utility parameter are sensible. In addition, our estimatedhabit function generates a positive stochastic discount factor (SDF)proxy and performs well in explaining cross-sectional stock return data.We find that an internal habit SDF proxy can explain a cross-section ofsize and book-market sorted portfolio equity returns better than (i) theFama and French (1993) three-factor model, (ii) the Lettau and Ludvigson(2001b) scaled consumption CAPM model, (iii) an external habit SDFproxy, (iv) the classic CAPM, and (v) the classic consumption CAPM.

Theory predicts that a broad wave of sentiment willdisproportionately affect stocks whose valuations are highly subjectiveand are difficult to arbitrage. We test this prediction by studying howthe cross-section of subsequent stock returns varies with proxies forbeginning-of-period investor sentiment. When sentiment is low,subsequent returns are relatively high on smaller stocks, highvolatility stocks, unprofitable stocks, non-dividend-paying stocks,extreme-growth stocks, and distressed stocks, consistent with an initialunderpricing of these stocks. When sentiment is high, on the other hand,these patterns attenuate or fully reverse. The results are consistentwith theoretical predictions and are unlikely to reflect an alternativeexplanation based on compensation for systematic risks.

We introduce investor protection in a simple extensionof the two-period overlapping generations model of capital accumulationand study how it affects economic growth. Investor protection ispositively related to risk-sharing. As is standard in models ofinvestment with risk-averse agents, better protection (better risksharing) results in a larger demand for capital. This is the demandeffect. A second effect, which we call the supply effect, follows fromgeneral equilibrium restrictions. For a given aggregate capital stock,better protection (i.e., a higher demand schedule) implies a higherinterest rate. The aggregate resource constraint then implies lowerincome for the entrepreneurs (the younger cohort). As a result, currentsavings and the supply of capital in the following period decrease. Itturns out that the strength of the supply effect is greater, the tighterthe restrictions on capital flows. Therefore our model predicts that thepositive effect of investor protection on growth is stronger forcountries with lower restrictions. We find that the data provides somesupport for this prediction.

We allowmoney-holders to choose the intensities with which they search fortrading partners, so inflation affects the frequency of trade as well asthe quantity of output produced in each trade. We consider the standardpricing mechanism for search models, i.e. ex-post bargaining, as well asa notion of competitive pricing. If prices are bargained over, theequilibrium is generically inefficient and an increase in inflationreduces buyers&rsquo; search intensities, output and welfare. If pricesare posted and buyers can direct their search, search intensities areincreasing with inflation for low inflation rates and decreasing forhigh inflation rates. The Friedman Rule achieves the first bestallocation and inflation always reduces welfare even though it can havea positive effect on output for low inflation rates.

In this paper, we develop a new model ofthe equilibrium premium in the foreign exchange market that replaces theREH with the Imperfect Knowledge Forecasting (IKF) framework. Because wemaintain that agents must cope with imperfect knowledge and that theyare not grossly irrational, our IKF approach imposes only qualitativeconditions on the formation of individual forecasting models and theirupdating. We also develop a dynamic extension of the originalformulation of Kahneman and Tversky&rsquo;s prospect theory. We findthat under IKF and dynamic prospect theory, the equilibrium premium onforeign exchange is positively related to the gap between the aggregateforecast of the exchange rate and its historical benchmark level. Wetest this implication, using survey data on the German mark-U.S. dollarexchange rate, and find that the behavior of the ex ante premium onforeign exchange is consistent with our model of the premium.

If debts can only be enforced to the extent thatthey are collateralized by housing wealth, a decrease in the value ofhousing collateral endogenously increases exposure to idiosyncraticrisk. This increases the cross-sectional consumption growth dispersionacross regions and it reduces the amount of regional income risk shared.We investigate risk-sharing patterns for the 30 largest US metropolitanareas and find empirical support for the housing collateral channel. Intimes when housing collateral is scarce, the dispersion of consumptiongrowth relative to income growth is twice as high as when collateral isabundant. A structural estimation of the model's consumption dynamicsimplies a time path for consumption growth dispersion that matches theone in the data. The housing collateral effect is the key element thatenables this match.

Themodel describes a scale-independent economy, with a unique stochasticinvestment opportunity set. Local correlation between the stochasticinterest rate and time-varying market price of risk can be determinedendogenously and leads to correct predictions on the sign and magnitudeof several major empirical puzzles in both equity and bond markets. Inthe empirical part of the paper, we calibrate our model, simultaneously,to the equity premium puzzle, the riskfree rate puzzle, and theexpectations puzzle, and show that the three puzzles are completelyresolved under reasonable parameter values. Thus, we establish,conclusively, the inextricable link between the equity and bond markets,both theoretically and empirically.

This literature is vast with boththe academic and practitioner communities having proposed a wide varietyof models and model-selection criteria. Central to all pricing models,implicitly or explicitly, are: (i) the identity of the state vector:whether it is latent or observable and, in the latter case, whichobservable series; (ii) the law of motion (conditional distribution) ofthe state vector under the pricing measure; and (iii) the functionaldependence of the short-term interest rate on this state vector. Aprimary objective, then, of research on fixed-income pricing has beenthe selection of these ingredients to capture relevant features ofhistory, given the objectives of the modeler, while maintainingtractability, given available data and computational algorithms.Accordingly, we overview alternative conceptual approaches tofixed-income pricing, highlighting some of the tradeoffs that haveemerged in the literature between the complexity of the probabilitymodel for the state, data availability, the pricing objective, and thetractability of the resulting model.

The introduction of non-redundant assets can endogenouslymodify the participation set, reduce the covariance between dividendsand participants&rsquo; consumption and thus lead to lower risk premia.This mechanism is demonstrated in a tractable exchange economy with afinite number of macroeconomic factors. Agents can freely borrow andlend, but must pay a fixed entry cost to invest in risky assets.Security prices and the participation structure are jointly determinedin equilibrium. The model is consistent with several features offinancial markets over the past few decades: substantial financialinnovation; a sharp increase in investor participation; improved riskmanagement practices; a slight increase in interest rates; and areduction in risk premia.

Bankruptcy improves on non-exclusivecontractual relationships but is not a perfect substitute forexclusivity ex ante. We characterize the effect of bankruptcy provisionson the equilibrium contracts which borrowers use to raise financing.

In the presence ofunhedgeable inflation risk, there exist multiple pricing kernels thatproduce the same bond prices, but a unique pricing kernel equal to themarginal utility of the investor. We apply our method to a three-factorGaussian model with a time-varying price of risk that captures thefailure of the expectations hypothesis seen in the data. We extend thismodel to account for time-varying expected inflation, and estimate themodel with both inflation and term structure data. The estimates implythat the bond portfolio for the long-run investor looks very differentfrom the portfolio of a mean-variance optimizer. In particular, thedesire to hedge changes in term premia generates large hedging demandsfor long-term bonds.

Much of the literature to date has allowed risk loadings to betime-varying while imposing the assumption that conditional performanceis constant. We develop a new methodology that allows conditionalperformance to be a function of information available at the start ofthe period. This methodology uses the Euler equation restriction thatcomes out of the factor model rather than the beta pricing formulaitself. The Euler equation restrictions that we develop can be estimatedusing GMM. It is also possible to allow the factor returns to havelonger data series than the mutual fund series as in Stambaugh (1997).We use our method to assess the conditional performance of funds in theElton, Gruber and Blake (1996) mutual fund data set. Using dividendyield to track the business cycle, we find that conditional mutual fundperformance moves with the business cycle, with all fund types exceptgrowth performing better in downturns than in peaks. The converse holdsfor growth funds, which do better in peaks than in downturns.

Evidence and Theory<br/><br/>Krueger, Dirk; Perri, Fabrizio<br/><br/>Abstract: This paper first documents the evolution of the cross-sectional incomeand consumption distribution in the US in the past 25 years. Using datafrom the Consumer Expenditure Survey we find that a rising incomeinequality has not been accompanied by a corresponding rise inconsumption inequality. Over the period from 1972 to 1998 the standarddeviation of the log of after-tax labor income has increased by 20%while the standard deviation of log consumption has increased less than2%. Furthermore income inequality has increased both between and withineducation groups while consumption inequality has increased betweeneducation groups but mildly declined within groups. We then argue thatthese empirical findings are consistent with the hypothesis that anincrease in income volatility has been an important cause of theincrease in income inequality, but at the same time has lead to anendogenous development of credit markets, allowing households to bettersmooth their consumption against idiosyncratic income fluctuations. Wedevelop a consumption model in which the sharing of income risk islimited by imperfect enforcement of credit contracts and in which thedevelopment of financial markets depends on the volatility of theindividual income process. This model is shown to be quantitativelyconsistent with the joint evolution of income and consumption inequalityin US, while other commonly used consumption models are not.

We establish thatthe upward trend in micro volatility is not simply driven by acompositional bias in the sample studied. We argue that this new factrenders obsolete the proposed explanations for the decline in aggregatevolatility and that, given the symmetry of the diverging trends at themicro and macro level, a common explanation is highly likely. Weconclude by describing one such theory driven by market integration.

I build a simple modelwhere managers are prone to over invest and where shareholders are morewilling to tolerate such a behavior in good times. The modelsuccessfully explains the average profit differences as well as thecyclical behavior of sales, employment and investment for firms withdifferent governance qualities. The quantitative results suggest thatgovernance conflicts can explain 30% of aggregate volatility.

The dataset used in the study includes quarterly datafor Argentina during 1983-2000 and for Brazil, Mexico, Korea, andPhilippines, during 1994-2000. In this sample, interest rates are veryvolatile, strongly countercyclical, and strongly positively correlatedwith net exports. Output is very volatile and consumption is morevolatile than output. These regularities are common to all emergingeconomies in the sample, but are not observed in a developed economysuch as Canada. The paper presents a dynamic general equilibrium modelof a small open economy, in which (i) firms have to pay for a fractionof the input bill before production takes place, and in which (ii) thelabor supply is independent of consumption. Using a version of themodel calibrated to Argentina&rsquo;s economy, we find that interestrate shocks alone can explain 50% of output fluctuations and cangenerate business cycle patterns consistent with the regularitiesdescribed above and with the major booms and recessions in Argentina inthe last two decades. We conclude that interest rates are an importantfactor for explaining business cycles in emerging economies and furtherresearch should be devoted to fully understand their determination.

Not necessarily. We set up a model in which the equilibriumnumber of takeovers is constrained efficient. Yet, upon news of atakeover, a target&rsquo;s price rises, the bidder&rsquo;s price falls,and, most of the time the joint value of the target and acquirer also falls.

Rather, it captures a dynamic interactionbetween aggregate financial income and aggregate labor income. I alsoshow that existing specifications of consumption habit can be extendedto incorporate a stochastic shock, which is interpreted as the laborincome shock. As a result of these two innovations, I show that a habitformation model can explain the equity premium, equity volatility, andrisk free rate puzzles simultaneously, and provide an equilibriumjustification for the predictability of equity and bond returns bydividend/pride ration and term spreads - all in terms of observablesample moments of aggregate dividend income and labor income growthrates and reasonable values of risk aversion coefficient and thesubjective discount rate. To substantiate these claims, I present anextension of the Breeden-Lucas CCAPM by incorporating a particular formof heterogeneity assumption and a particular form of limitedparticipation assumption. The resulting model features a richertechnological specification (from the perspective of a productioneconomy) or a richer standard assumptions of constant relative riskaversion, complete markets, and frictionless trading from theperspective of the marginal investor.

We show that the absence of free lunches in such models isequivalent to the existence of a family of absolutely continuousprobability measures for which the normalized price processes aremartingales, conditional to any possible future event. This is a weakercondition than the absence of free lunches in frictionless models, whichis equivalent to the existence of an equivalent martingale measure. Wealso show that the only arbitrage free pricing rules on the set ofattainable contingent claims are those that are equal to the sum of anexpected value with respect to any absolutely continuous martingalemeasure and of a bounded fixed cost functional. Moreover, these pricingrules are the only ones to be viable as models of economic equilibrium.

However,tractable versions of these models typically need strong assumptionsthat make them ill-suited for studying monetary policy. We propose aframework based on explicit micro foundations within which macro policycan be analyzed. The model is both analytically tractable and amenableto quantitative analysis. We demonstrate this by using it to estimatethe welfare cost of inflation. We find much higher costs than theprevious literature: our model predicts that going from 10% to 0%inflation can be worth between 3% and 5% of consumption.

A decrease in house prices reduces the collateralvalue of housing, increases household exposure to idiosyncratic risk,and increases the conditional market price of risk. The modelquantitatively accounts for conditional asset pricing moments,cross-sectional variation in value portfolio returns and keyunconditional asset pricing moments. The increase of the equity premiumand Sharpe ratio when collateral is scarce matches the increase observedin US data. The model also generates a return spread of value firms overgrowth firms of the magnitude observed in the data. Assets with payoffsthat lay farther in the future are less risky. Growth stocks are suchlong duration assets.

It considers a frictionallabor market where production units are subject to idiosyncratic shocksand jobs are created and destroyed as in Mortensen and Pissarides(1994). An aggregate production function is derived by aggregatingacross production units in equilibrium. The level of TFP is explicitlyshown to depend on the underlying distribution of shocks as well as onall the characteristics of the labor market as summarized by thejob-destruction decision. The model is also used to study the effects oflabor-market policies on the level of measured TFP. Wed, 28 Nov 2001 22:58:59 GMT
