contagion as a wealth effect financial contagion is described as a wealth effect in a continuous time model with two risky assets and three types of traders noise traders trade randomly in one market long term investors provide liquidity using a linear rule based on fundamentals convergence traders with logarithmic utility trade optimally in both markets asset price dynamics are endogenously determined numerically as functions of endogenous wealth and exogenous noise when convergence traders lose money they liquidate positions in both markets this creates contagion in that returns become more volatile and more correlated contagion reduces benefits from portfolio diversification and raises issues for risk management during the f inancial panic associated with the default of the russian government in august 1998 and the subsequent collapse of the hedge fund long term capital management numerous hedge funds banks and securities firms tried simultaneously to reduce exposures to a variety of financial instruments such as russian bonds brazilian stocks u s mortgages spreads between on therun and off the run government securities and spreads between swaps and u s treasuries although the fundamental values of these positions would appear to have little correlation during this financial crisis the asset prices in these markets exhibited the following common empirical pattern 1 financial intermediaries suffered losses as prices moved against their positions 2 market depth and liquidity decreased simultaneously in several markets 3 the volatility of prices increased simultaneously in several markets and

global factors and emerging market spreads this paper shows that a large fraction of the variability of emerging market bond spreads is explained by the evolution of global factors such as risk appetite as reflected in the spread of high yield corporate bonds in developed markets global liquidity measured by the international interest rates and contagion from systemic events like the russian default this link has remained relatively stable over the history of the emerging market class is robust to the inclusion of country specific factors and helps provide accurate long run predictions overall the results highlight the critical role played by exogenous factors in the evolution of the borrowing cost faced by emerging economies

sovereign default risk and the u s equity market i develop a two country general equilibrium model with firms governments and endogenous default decisions this paper shows that the risk of sovereign default abroad is important in the explanation of the level and the volatility of u s equity returns the intuition is that negative economic shocks deteriorate the fiscal situation of foreign governments thereby increasing the risk of a sovereign default that would trigger a local contraction in economic growth the rise in the risk of an economic slowdown abroad amplifies the direct eect of these shocks on the level and the volatility of equity returns in the u s through i a decrease in the present value of future firm earnings due to the unfavorable adjustment of the real exchange rate for u s exporters and ii a fall in u s equity prices that originates from the investors incentive to rebalance their portfolio towards risk free securities the amplification eect is strongest during periods of financial distress when the risk of corporate default is high in the u s a structural estimation of the model provides strong support for this prediction using monthly data for brazil and the u s over the period 1994 2008

using price distributions to estimate search costs we show how the equilibrium restrictions implied by standard search models can be used to estimate search cost distributions using price data alone we consider both sequential and nonsequential search strategies and develop estimation methodologies that exploit equilibrium restrictions to recover estimates of search cost heterogeneity that are theoretically consistent with the search models we illustrate the method using online prices for several economics and statistics textbooks

borrowing high versus borrowing higher price dispersion and shopping behavior in the u s credit card market we document substantial cross individual dispersion in u s credit card borrowing costs even after controlling for borrower risk and card characteristics that remaining dispersion arises because cross lender pricing heterogeneity generates dispersion in annual percentage rate apr offers to borrowers and borrowers vary in shopping intensity our empirics match administrative data to self reported card shopping intensity and use instruments suggested by fair lending law to account for the endogeneity between aprs and search the results show that shoppers versus nonshoppers pay aprs as different as those paid by borrowers in the best versus worst credit score deciles we discuss implications for policy and practice

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

tax deferred accounts constrained choice and estimation of individual saving the paper analyzes the effect of tax deferred individual retirement accounts iras in the united states on net individual saving the results are based on a model of constrained optimization with the limit on tax deferred saving the principle constraint the estimates suggest that contributions to iras represent substantial net saving increases were the ira limit to be increased only about 10 to 20 of resulting increase in ira contributions would be taken from other savings about 50 would come from reduced consumption and about 35 from reduced

interest rate changes and borrower search behavior abstract borrower search behavior regarding an outside lender is correlated with interest rate changes the results of a survey among german households reveal that surprisingly few mortgage borrowers switch to an outside lender when refinancing in a period of declining interest rates although non switching borrowers face significantly higher interest rates a laboratory experiment which adds the case of rising interest rates reveals that borrowers efforts to screen offers by outside lenders are significantly higher when interest rates rise than when they fall this behavior cannot be reconciled with alternative explanations overall several billion p a are transferred to lenders

the debt equity choice when firms adjust their capital structures they tend to move toward a target debt ratio that is consistent with theories based on tradeoffs between the costs and benefits of debt in contrast to previous empirical work out tests explicitly account for the fact that firms may face impediments to movements toward their target ratio and that the target ratio may change over time as the firm s profitability and stock price change a separate analysis of the size of the issue and repurchase transactions suggests that the deviation between the actual and the target ratios plays a more important role in the repurchase decision than in the issuance decision

international risk cycles abstract recent work in international finance suggests that exchange rate puzzles can be accounted for if 1 aggregate uncertainty is time varying and 2 countries have heterogeneous exposures to a world aggregate shock we embed these features in a standard two country real business cycle framework and calibrate the model to equity risk premia in low and high interest rates countries unlike traditional real business cycle models our model generates volatile exchange rates a large currency forward premium excess comovement of asset prices relative to quantities and an imperfect correlation between relative consumption growth and exchange rates our model implies however that high interest rate countries have smoother quantities equity returns and interest rates than low interest rate countries contrary to the data

prominence complexity and pricing this paper analyzes prominence in a homogeneous product market where two firms simultaneously choose both prices and price complexity levels complexity limits competing offers comparability and results in consumer confusion confused consumers are more likely to buy from the prominent firm in equilibrium there is dispersion in both prices and price complexity the nature of equilibrium depends on prominence compared to its rival the prominent firm makes higher profit associates a smaller price range with lowest complexity puts lower probability on lowest complexity and sets a higher average price however higher prominence may benefit consumers and conditional on choosing lowest complexity the prominent firm s average price is lower which is consistent with confused consumers bias

commodity trade and international risk sharing how much do financial markets matter abstract this paper evaluates the social gains from international risk sharing in some simple general equilibrium models with output uncertainty a simulation model calibrated to selected moments of u s and japanese data estimates the incremental loss from a ban on international portfolio diversification to be on the order of 0 20 percent of output per year even the theoretical gains from asset trade may disappear under alternative sets of assumptions on preferences and technology the paper argues that the small magnitude of potential trade gains may help explain the apparently inconsistent findings of empirical studies on the degree of international capital mobility

is it punishment sovereign defaults and the decline in trade sovereign defaults are associated with declines in defaulting countries trade are these declines the result of trade sanctions as the trade sanctions argument of sovereign borrowing would suggest we devise an empirical strategy to evaluate this issue based on the idea that if trade sanctions are causing the declines bilateral trade with creditor countries should fall more than trade with other countries we find that this is not the case the analysis does not yield much evidence of broader punishment strategies including a league of major creditors either these results contradict the predictions of the trade sanctions theory of sovereign borrowing

a new approach to measuring financial contagion this article proposes a new approach to evaluate contagion in financial markets our measure of contagion captures the coincidence of extreme return shocks across countries within a region and across regions we characterize the extent of contagion its economic significance and its determinants using a multinomial logistic regression model applying our approach to daily returns of emerging markets during the 1990s we find that contagion is predictable and depends on regional interest rates exchange rate changes and conditional stock return volatility evidence that contagion is stronger for extreme negative returns than for extreme positive returns is mixed

multidimensional incentive compatibility and mechanism design abstract incentive compatibility conditions are characterized in general for problems in which several goods are to be allocated and agents types are multidimensional two questions of monopoly pricing under multidimensional uncertainty are then analyzed first we find the optimal nonlinear pricing scheme when the monopolist knows only the distribution of an arbitrarily parameterized family of demand curves and second we solve for the optimal bundling policy for a multiproduct monopolist

measuring the agency cost of debt we adapt a contingent claims model of the firm to reflect the incentive effects of the capital structure and thereby to measure the agency costs of debt an underlying model of the firm and the stochastic features of its product market are analyzed and an optimal operating policy is chosen we identify the change in operating policy created by leverage and value this change the model determines the value of the firm and its associated liabilities incorporating the agency consequences of debt the optimal capital structure for a firm is now widely regarded to be determined by a broad range of factors including a mix of tax effects the various agency problems associated with different securities and the various costs of issuing securities including the costs created by adverse selection while the existence of a theoretical optimum has been demonstrated in a variety of papers a less explored area has been the construction of detailed models that enable us to measure each of the relevant factors for a particular company and thereby to determine the actual optimal mix for that firm this gap in our understanding is particularly glaring in the case of agency costs in order to allow a careful modelling of strategic relations the parameters of most agency models are either so simplified that it is impossible to associate them with measurable parameters of a real world case or else the models simply abstract from certain critical factors such as a robust measure of price risk that must be incorporated into any real application for example although we now understand that sinking funds dividend restrictions and other bond covenants help to resolve the conflict of interest between bondholders and equity we do not yet have much in the way of models with which to determine the optimal parameters of these very covenants contingent claims models can provide a consistent framework for multiperiod valuation that properly accounts for risk but they usually abstract from the agency factors entering capital structure decisions when using a contingent claims model to value a firm s securities it is common to take the value of the firm itself as governed by an exogenously defined stochastic process the value of the firm s securities are then derived from this underlying value and as merton 1974 points out in his paper on the pricing of risky debt the modigliani miller theorem obtains so that the value of the firm is independent of the value and the type of debt in order to apply the contingent claims techniques to a setting in which agency problems are central some adaptation is necessary in this paper we

the role of portfolio constraints in the international propagation of shocks we study the comovement among stock prices and exchange rates in a three good three country centre periphery dynamic equilibrium model in which the centre s agents face portfolio constraints we characterize equilibrium in closed form for a broad class of portfolio constraints solving for stock prices terms of trade and portfolio holdings we show that portfolio constraints generate wealth transfers between the periphery countries and the centre which increase the comovement of the stock prices across the periphery we associate this excess comovement caused by portfolio constraints with the phenomenon known as contagion the model generates predictions consistent with other important empirical results such as amplification and flight to quality effects copyright 2008 wiley blackwell

the morphology of price dispersion this paper is a study of the shape and structure of the distribution of prices at which an identical good is sold in a given market and time period we find that the typical price distribution is symmetric and leptokurtic with a standard deviation between 19 and 36 only 10 of the variance of prices is due to variation in the expensiveness of the stores at which a good is sold while the remaining 90 is due in approximately equal parts to differences in the average price of a good across equally expensive stores and to differences in the price of a good across transactions at the same store we show that the distribution of prices that households pay for the same bundle of goods is approximately normal with a standard deviation between 9 and 14 half of this dispersion is due to differences in the expensiveness of the stores where households shop while the other half is mostly due to differences in households choices of which goods to purchase at which stores we find that households with fewer employed members pay lower prices and do so by visiting a larger number of stores rather than by shopping more frequently

life cycle prices and production we use scanner data and time diaries to document how households substitute time for money through shopping and home production we document substantial heterogeneity in prices paid for identical goods for the same area and time with older households shopping the most and paying the lowest prices doubling shopping frequency lowers a good s price by 7 to 10 percent we estimate the shopper s price of time and use this series to estimate an elasticity of substitution between time and goods in home production of roughly 1 8 the observed life cycle time allocation implies a consumption series that differs markedly from expenditures

correlations in price changes and volatility across international stock markets the short run interdependence of prices and price volatility across three major international stock markets is studied daily opening and closing prices of major stock indexes for the tokyo london and new york stock markets are examined the analysis utilizes the autoregressive conditionally heteroskedastic arch family of statistical models to explore these pricing relationships evidence of price volatility spillovers from new york to tokyo london to tokyo and new york to london is observed but no price volatility spillover effects in other directions are found for the pre october 1987 period article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

price dispersion in mortgage markets using transaction level data on canadian mortgage contracts we document an increase in the average discount negotiated off the posted price and in rate dispersion our aim is to identify the beneficiaries of discounting and to test whether dispersion is caused by price discrimination the standard explanation for dispersion in credit markets is risk based pricing our contracts are guaranteed by government backed insurance so risk cannot be the main factor we find that lenders set prices that reflect consumer bargaining leverage not just costs the presence of dispersion implies a lack of competition but our results show this to be consumer specific

sovereign defaults by currency denomination abstract this paper explores the drivers of sovereign default in 100 countries over the period 1996 2012 we build a new data set of sovereign defaults and find that default events for local and foreign currency bonds are equally likely however governments default under different economic and financial conditions depending on the currency in which bonds are issued the explained variation in default probability rises from 43 to 62 when we account for differences in currency denomination we also provide evidence that global factors and market sentiment which are known to drive sovereign spreads do not help explain the probability of sovereign default hence these factors appear to affect the price of sovereign credit risk although not the risk itself

volatility dependence and contagion in emerging equity markets abstract in this paper we use weekly stock market data for a group of latin american countries to analyze the behavior of volatility through time we are particularly interested in understanding whether periods of high volatility are correlated across countries the analysis uses both on univariate and bivariate switching volatility models our results do not rely on the correlation coefficients but on the co dependence of volatility regimes the results indicate that high volatility episodes are in general short lived lasting from 2 to 12 weeks we find strong evidence of volatility co movements across countries especially among the mercosur countries

on crises contagion and confusion abstract since the tequila crisis of 1994 1995 the asian flu of 1997 and the russian virus of 1998 economists have been busy producing research on the subject of contagion yet few studies have examined empirically through which channels the disturbances are transmitted if there are indeed fundamental reasons for the spillovers we observe we attempt to fill this gap by analyzing how both trade links and the largely ignored financial sector links influence the pattern of fundamentals based contagion we examine the role of international bank lending the potential for cross market hedging and bilateral and third party trade in the propagation of crises

asset prices and exchange rates in this paper we study the implications of introducing demand shocks and trade in goods into an otherwise standard international asset pricing model trade in goods gives rise to an additional channel of international propagation through the terms of trade absent in traditional single good asset pricing models the inclusion of demand shocks helps overturn many unrealistic implications of existing international flnance models in which productivity shocks are the sole source of uncertainty our model generates a rich set of implications on how stock bond and foreign exchange markets co move we solve the model in closed form which yields a system of equations that can be readily estimated empirically our estimation validates the main predictions of the theory

consumer confusion in the mortgage market evidence of less than a perfectly transparent and competitive market consumers often shop with incomplete infor mation about prices even when prices have a take it or leave it character as at the grocery store most shoppers don t know the price of milk at all nearby stores in markets where prices are dickered finding the best deal is more challenging the car shopper paying cash has to make offers and counteroffers to get an idea of the lowest price acceptable to a dealer and work one dealer against another in the mortgage market the shopper s task is even more difficult not only are prices dickered but price has two dimensions the interest rate on the loan and

foreign currency debt financial crises and economic growth a long run view what are the costs of hard currency liabilities after being implicated in the global financial instability of the late 1990s the costs are widely believed to be large and as a result many emerging markets have pushed to minimize currency mismatches we study the growth effects of exposure to foreign currency debt using data from two periods of international financial integration 1880 1913 and 1973 2002 for over 45 countries hard currency debt is associated with increased risks of currency and debt crises in both periods especially when a country s macroeconomic financial fundamentals are weak we find the risk of financial crisis associated with hard currency debts translated into significantly diminished growth rates however we also find evidence that strong financial development and policy credibility attenuate the crisis risks associated with high exposure to hard currency debt which has implications for eastern european countries where large current account deficits and high levels of hard currency debt are believed to pose financial risks in this region some countries have adopted flexible exchange rates and avoided foreign currency debt several others have built up large net foreign currency liabilities and are exposed to a significant likelihood of a financial crisis in the near future

firm specific information and the correlation between individual stocks and bonds abstract this paper examines the correlation between the returns on individual stocks and the yield changes of individual bonds issued by the same firm and finds that they are negatively and contemporaneously correlated this suggests that individual stocks and bonds are driven by firm specific information that is predominantly related to the mean rather than the variance of the firm s underlying assets furthermore i find that lagged stock returns have explanatory power for current bond yield changes while current stock returns are unrelated to lagged bond yield changes this shows that stocks lead bonds in reflecting firm specific information

mortgage risks debt literacy and financial advice a limited understanding of mortgage contracts and the risks involved may have contributed to the outbreak of the 2007 2008 financial crisis we developed a special questionnaire relating mortgage loan decisions to financial knowledge and financial advice our results demonstrate that homeowners appear to be well aware of mortgage risks large loans relative to home value are perceived as riskier as are loans with large mortgage payments relative to income and loans linked to investment vehicles homeowners with riskier mortgages indicated that they could encounter financial problems should house prices or their income decline homeowners with relatively low debt literacy are more likely to take out traditional mortgages with principal repayments over the maturity of the loan riskier mortgages are more prevalent among homeowners with a better understanding of loan contracts financially less sophisticated homeowners consulting mortgage brokers too hold riskier mortgages

search frictions and market power in negotiated price markets we provide a framework for empirical analysis of negotiated price markets using mortgage market data and a search and negotiation model we characterize the welfare impact of search frictions and

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

growth in the shadow of expropriation we propose a tractable variant of the open economy neoclassical growth model that emphasizes political economy and contracting frictions the political economy frictions involve a preference for immediate spending while the contracting friction is a lack of commitment regarding foreign debt and expropriation we show that the political economy frictions slow an economy s convergence to the steady state due to the endogenous evolution of capital taxation the model rationalizes why openness has different implications for growth depending on the political environment why institutions such as the treatment of capital income evolve over time why governments in countries that grow rapidly accumulate net foreign assets rather than liabilities and why foreign aid may not affect growth

unhealthy insurance markets search frictions and the cost and quality of health insurance we analyze the effect of search frictions in the market for commercial health insurance frictions increase insurance premiums enough to transfer 13 2 percent of consumer surplus from fully insured employer groups to insurers approximately 34 4 billion in 1997 and increase insurance turnover by 64 percent for the average pol icy this rent transfer harms consumers and when combined with heightened turnover reduces incentives to invest in future health we also find that a publicly financed insurance option can improve the efficiency of private insurance markets by reducing search fric tion induced distortions in pricing and marketing efforts jel d83 g22 i18 in the united states health insurance for those under age 65 is typically provided through group plans purchased by employers from commercial insurers health insurance is a complex multi attribute service so employers looking to buy insur ance face a difficult shopping problem savvy purchasers must consider which of the many drugs their employees might use are in the insurer s formularies which local physicians are part of the insurer s provider network and what copays fees and deductibles apply to which pharmaceuticals providers and services comparison shopping is made even more difficult by the fact that many aspects of insurance involve commitments to provide services under hard to anticipate contingencies medical underwriting by insurers and the great profusion of insurance products raises administrative costs and increases the complexity of an employer group s

sovereign debt booms in monetary unions leveraging the higher ination credibility of other countries via a currency union we show that an increase in ination credibility delivers an invitation to borrow raising the maximum borrowing limit of the country and reducing any incentive to save conditional on a nominal interest rate the government has an ex post incentive to inate away the real value of its bonds however creditors anticipate this temptation ex ante pricing the ex post ination into the nominal interest rate the country therefore bears the cost of high ination with no reduction of debt in real terms including the costs associated with ex post ination a

the consumption effects of the 2007n2008 financial crisis evidence from households in denmark did the financial crisis in 2007 2008 spread from distressed banks to households through a contraction of the credit supply we study this question with a dataset that contains observations on all accounts in danish banks as well as comprehensive information about individual account holders and banks we document that banks exposed to the financial crisis reduced their lending relative to nonexposed banks which in turn caused a significant decrease in the borrowing and spending of their customers the effects were persistent borrowing remained lower through the postcrisis years and spending foregone during the crisis was not recovered

choice inconsistencies among the elderly evidence from plan choice in the medicare part d program comment consumers enrollment decisions in medicare part d can be explained by abaluck and gruber s 2011 model of utility maximization with psychological biases or by a neoclassical version of their model that precludes such biases we evaluate these competing hypotheses by applying nonparametric tests of utility maximization and model validation tests to administrative data we find that 79 percent of enrollment decisions from 2006 to 2010 satisfied basic axioms of consumer theory under the assumption of full information the validation tests provide evidence against widespread psychological biases in particular we find that precluding psychological biases improves the structural model s out of sample predictions for consumer behavior

equilibrium asset prices and exchange rates abstract in a two country two good world we construct an intertemporal international general equilibrium for two logarithmic representative agents financial markets are fully integrated and independently incomplete the equilibrium expected rate of change of the exchange rate increases with the differential of interest rates and the volatility of the domestic equity markets and decreases with the covariance between domestic and foreign equity markets the equilibrium volatility of the exchange rate is the sum of the volatilities due to idiosyncratic factors in the financial markets and a term that represents the difference of weights in the common international factor

a model of focusing in economic choice we present a generally applicable theory of focusing based on the hypothesis that a person focuses more on and hence overweights attributes in which her options dier more our model predicts that the decisionmaker is too prone to choose options with concentrated advantages relative to alternatives but maximizes utility when the advantages and disadvantages of alternatives are equally concentrated in intertemporal choice because the relative concentrations of an option s costs and benets can be dierent from the perspective of a single period and the perspective of the entire choice problem the decisionmaker often exhibits a form of time inconsistency she is present biased when the costs of current misbehavior are distributed over many future dates such as in harmful consumption but future biased when the benet of many

a more general model of price complexity this paper considers a model of competition in prices and price complexity levels which accommodates concave and convex confusion technologies in symmetric equilibrium the probability of using high complexity increases in the number of firms in the limit as the number of competitors goes to infinity firms use high complexity almost surely but the impact on consumer welfare depends on the characteristics of the confusion technology specifically industry profits converge to the highest level with concave confusion technologies and to the lowest level when with convex confusion technologies an improvement in consumer sophistication increases consumer welfare but does not reduce market complexity

inferior products and profitable deception we analyse conditions facilitating profitable deception in a simple model of a competitive retail market firms selling homogenous products set anticipated prices that consumers understand and additional prices that naive consumers ignore unless revealed to them by a firm where we assume that there is a binding floor on the anticipated prices our main results establish that bad products those with lower social surplus than an alternative tend to be more reliably profitable than good products specifically 1 in a market with a single socially valuable product and sufficiently many firms a deceptive equilibrium in which firms hide additional prices does not exist and firms make zero profits but perversely 2 if the product is socially wasteful then a profitable deceptive equilibrium always exists furthermore 3 in a market with multiple products since a superior product both diverts sophisticated consumers and renders an inferior product socially wasteful in comparison it guarantees that firms can profitably sell the inferior product by deceiving consumers we apply our framework to the mutual fund and credit card markets arguing that it explains a number of empirical findings regarding these industries

heterogeneous preferences and equilibrium trading volume abstract the representative agent lucas model stresses aggregate risk and hence does not allow us to study the impact of agents heterogeneity on the dynamics of equilibrium trading volume in this paper we investigate under what conditions non informational heterogeneity i e differences in preferences and endowments leads to nontrivial trading volume in equilibrium we present a non informational no trade theorem that provides necessary and sufficient conditions for zero equilibrium trading volume in a continuous time lucas market model with heterogeneous agents multiple goods and multiple securities we explain in detail how no trade equilibria are related to autarky equilibria portfolio autarky equilibria and peculiar financial market equilibria which play an important role in the literature on international risk sharing

financial literacy financial education and downstream financial behaviors policy makers have embraced financial education as a necessary antidote to the increasing complexity of consumers financial decisions over the last generation we conduct a meta analysis of the relationship of financial literacy and of financial education to financial behaviors in 168 papers covering 201 prior studies we find that interventions to improve financial literacy explain only 0 1 of the variance in financial behaviors studied with weaker effects in low income samples like other education financial education decays over time even large interventions with many hours of instruction have negligible effects on behavior 20 months or more from the time of intervention correlational studies that measure financial literacy find stronger associations with financial behaviors we conduct three empirical studies and we find that the partial effects of financial literacy diminish dramatically when one controls for psychological traits that have been omitted in prior research or when one uses an instrument for financial literacy to control for omitted variables financial education as studied to date has serious limitations that have been masked by the apparently larger effects in correlational studies we envisage a reduced role for financial education that is not elaborated or acted upon soon afterward we suggest a real but narrower role for just in time financial education tied to specific behaviors it intends to help we conclude with a discussion of the characteristics of behaviors that might affect the policy maker s mix of financial education choice architecture and regulation as tools to help consumer financial behavior this paper was accepted by uri gneezy behavioral economics

diagnosing consumer confusion and sub optimal shopping effort theory and mortgage market evidence mortgage loans are leading examples of transactions where experts on one side of the market take advantage of consumers lack of knowledge and experience we study the compensation that borrowers pay to mortgage brokers for assistance from application to closing two findings support the conclusion that confused borrowers overpay for brokers services i a model of effective shopping shows that bor rowers sacrifice at least 1 000 by shopping from too few brokers ii borrowers who compensate their brokers with both cash and a commission from the lender pay twice as much as similar borrowers who pay no cash jel d12 d14 g21 we study a large and financially complex expenditure that the majority of consumers make only a few times in their lives the payment for mortgage origination services in these transactions information is not only imperfect but traditional market practices have likely contributed to consumer confusion these payments range from 0 to 30 000 for mortgages of normal size mortgage brokers receive payments from both borrowers and from wholesale lenders on most loans broker fees paid in cash by the borrower are usually broken down into more than a dozen individual items such as origination fee discount points funding fee and doc prep in addition to these cash payments about half of the value that the bor rower transfers to the broker takes the form of a payment from the wholesale lender to the mortgage broker the borrower bears the burden of this part of the payment in the form of a higher interest rate on the loan these payments compensate mortgage brokers for arranging mortgage loans we stress that this paper is about how and how much borrowers pay their brokers for origination services the broker is an administrator of the process of loan origination the broker bears none of the risk of default on the mortgage so that risk is not a determinant of the broker s compensation under standard theories of pricing because consumers enter the mortgage market infrequently and because features of the market make it difficult to learn the best price mortgage origination pricing

failure to refinance households that fail to refinance their mortgage when interest rates decline can lose out on substantial savings based on a large random sample of outstanding u s mortgages in december of 2010 we estimate that approximately 20 of households for whom refinancing would be optimal and who appeared unconstrained to do so had not taken advantage of the lower rates we estimate the present discounted cost to the median household who fails to refinance to be approximately 11 500

horses and rabbits trade off theory and optimal capital structure this paper examines optimal capital structure choice using a dynamic capital structure model that is calibrated to reflect actual firm characteristics the model uses contingent claim methods to value interest tax shields allows for reorganization in bankruptcy and maintains a long run target debt to total capital ratio by refinancing maturing debt using this model we calculate optimal capital structures in a realistic representation of the tra ditional trade off model in contrast to previous research the calculated optimal capital structures do not imply that firms tend to use too little leverage in practice we also esti mate the costs borne by a firm whose capital structure deviates from its optimal target debt to total capital ratio the costs of moderate deviations are relatively small suggesting that a policy of adjusting leverage infrequently is likely to be reasonable for many firms

sovereign credit spreads under good bad governance abstract this paper explores how sovereign credit spreads vary with the level of governance an analysis of 74 countries over the 2001 2016 period shows that sovereign credit default swap cds spreads decrease with government effectiveness particularly in countries exhibiting severe default risk high indebtedness and poor economic conditions we formulate a theoretical explanation for these findings using a structural model in which governments adjust default and debt policies based on their abilities to collect and use fiscal revenues the theory posits that more effective governments have less incentive to default and thus benefit from narrower credit spreads although they may choose higher indebtedness levels

sovereign risk and secondary markets conventional wisdom says that in the absence of default penalties sovereign risk destroys all foreign asset trade we show that this conventional wisdom rests on one implicit assumption that assets cannot be retraded in secondary markets without this assumption foreign asset trade is possible even in the absence of default penalties this result suggests a broader perspective regarding the origins of sovereign risk and its remedies sovereign risk affects foreign asset trade only if default penalties are insufficient and secondary markets work imperfectly to reduce its effects one can either increase default penalties or improve the working of secondary markets jel f34 g12 g15

product differentiation search costs and competition in the mutual fund industry a case study of s p 500 index funds we investigate the role that non portfolio fund differentiation and information search frictions play in creating two salient features of the mutual fund industry the large number of funds and the sizeable dispersion in fund fees in a case study we find that despite the financial homogeneity of s p 500 index funds this sector exhibits the fund proliferation and fee dispersion observed in the broader industry we show how extra portfolio mechanisms explain these features these mechanisms also suggest an explanation for the puzzling late 1990s shift in sector assets to more expensive and often newly entered funds an influx of highinformation cost novice investors

borrowing on the wrong credit card evidence from mexico abstract we establish new facts about the way consumers allocate debt among their credit cards using data for a representative sample of cardholders in mexico we find that relative prices are weak predictors of the allocation of debt purchases and payments consumers allocate a large fraction of their debt to high interest cards incurring a cost of 31 percent above the minimum using an experiment we find that consumers do not substitute in the price margin although they respond to salient temporary low interest offers we conclude that limited attention and mental accounting best rationalize our results and discuss implications for the market jel d14 g21 o12 o16

functional forms for labor supply and commodity demands with and without quantity restrictions one of the most important current questions in economic analysis is whether or not labor markets clear in the short run to answer this it is necessary to be able to distinguish between restricted and unrestricted behavior by consumers supplying labor this paper investigates the forms of preferences which lie behind linear models of labor supply and derives the functional forms for commodity demands which accompany them both with and without quantity restrictions in the labor market simple linkages between restricted and unrestricted demands are also considered as is the question of perfect aggregation over consumers in the presence of quantity restrictions

restoring rational choice the challenge of consumer financial regulation abstract this lecture considers the case for consumer financial regulation in an environment where many households lack the knowledge to manage their financial affairs effectively the lecture argu

long duration bonds and sovereign defaults abstract this paper extends the baseline framework used in recent quantitative studies of sovereign default by assuming that the government can borrow using long duration bonds this contrasts with previous studies which assume the government can borrow using bonds that mature after one quarter we show that when we assume that the government issues bonds with a duration similar to the average duration of sovereign bonds in emerging economies the model generates an interest rate that is substantially higher and more volatile than the one obtained assuming one quarter bonds this narrows the gap between the predictions of the model and the data which indicates that the introduction of long duration bonds may be a useful tool for future research about emerging economies our analysis is also relevant for the study of other credit markets

stochastic risk premiums stochastic skewness in currency options and stochastic discount factors in international economies abstract we develop models of stochastic discount factors in international economies that produce stochastic risk premiums and stochastic skewness in currency options we estimate the models using time series returns and option prices on three currency pairs that form a triangular relation estimation shows that the average risk premium in japan is larger than that in the us or the uk the global risk premium is more persistent and volatile than the country specific risk premiums and investors respond differently to different shocks we also identify high frequency jumps in each economy but find that only downside jumps are priced finally our analysis shows that the risk premiums are economically compatible with movements in stock and bond market fundamentals

macroeconomic effects of corporate default crisis a long term perspective abstract using an extensive data set on corporate bond defaults in the us from 1866 to 2010 we study the macroeconomic effects of bond market crises and contrast them with those resulting from banking crises during the past 150 years the us has experienced many severe corporate default crises in which 20 50 of all corporate bonds defaulted although the total par amount of corporate bonds has at times rivaled the amount of bank loans outstanding we find that corporate default crises have far fewer real effects than do banking crises these results provide empirical support for current theories that emphasize the unique role that banks and the credit and collateral channels play in amplifying macroeconomic shocks

why do markets move together an investigation of u s japan stock return comovements this article explores the fundamental factors that affect cross country stock return correlations using transactions data from 1988 to 1992 we construct overnight and intraday returns for a portfolio of japanese stocks using their nyse traded american depository receipts adrs and a matched sample portfolio of u s stocks we find that u s macroeconomic announcements shocks to the yen dollar foreign exchange rate and treasury bill returns and industry effects have no measurable influence on u s and japanese return correlations however large shocks to broadbased market indices nikkei stock average and standard and poor s 500 stock index positively impact both the magnitude and persistence of the return correlations stock return cross country covariances play a key role in international finance changes in these covariances affect the volatility of portfolios and asset prices as these covariances increase one expects that a fewer domestic risks are internationally diversifiable so portfolio volatility increases b the risk premium on the world market portfolio increases 1 c the cost of capital increases for individual firms and d the domestic version of the capm becomes increasingly inadequate 2 despite the important economic consequences of changes in cross country covariances the determinants of the levels and dynamics of these covariances have been little studied from an academic

employment in the great recession how important were household credit supply shocks i pool data from all large multimarket lenders in the united states to estimate how many of the over 7 million jobs lost in the great recession can be explained by reductions in the supply of mortgage credit i construct a mortgage credit supply instrument at the county level the weighted average by prerecession mortgage market shares of liquidity driven lender shocks during the recession the reduction in mortgage supply explains about 15 of the employment decline the job losses are concentrated in construction and finance

asset market linkages in crisis periods we characterize asset return linkages during periods of stress by an extremal dependence measure contrary to correlation analysis this nonparametric measure is not predisposed toward the normal distribution and can allow for nonlinear relationships our estimates for the g 5 countries suggest that simultaneous crashes between stock markets are much more likely than between bond markets however for the assessment of financial system stability the widely disregarded cross asset perspective is particularly important for example our data show that stock bond contagion is approximately as frequent as flight to quality from stocks into bonds extreme cross border linkages are surprisingly similar to national linkages illustrating a potential downside to international financial integration
