The recent global financial crisis reflects numerous breakdowns in the prudential discipline of financial firms. This paper discusses ways to strengthen micro- and macroprudential supervision and restore credible market discipline. The discussion notes that microprudential supervisors are typically assigned a variety of goals that sometimes have conflicting policy implications. In such a setting, the structure of the regulatory agencies and the priority given to prudential goals are critical to achieving those goals. The analysis of macroprudential supervision emphasizes that this supervisor must be both bold and modest: bold in seeking to understand the sources and distributions of systemically important risks and modest about what a supervisor can do without imposing overly restrictive regulations. Finally, the paper argues that the primary responsibility for risk management must rest with firms, not government supervisors. Unfortunately, systemic risk concerns have led governments to shield the private sector from the full losses that dull their incentive to discipline risk taking. This section of the paper suggests that deposit insurance reform, special resolutions for systemically important firms, and requirements that firms plan for their own resolution and contingent capital may all have a role to play in restoring effective market discipline.

During the late 1990s, the convergence of women's labor force participation rates to men's rates came to a halt. This paper explores the degree to which the role of education and marriage in women's labor supply decisions also changed over this time period. Specifically, this paper investigates women's decisions to exit the labor market upon the birth of a child. The results indicate that changing exit behavior among married, educated women at this period in their lives was not likely the driving force behind the aggregate changes seen in labor force participation. Rather, changes in exit rates among single women, particularly those less educated, are much more consistent with the changing pattern of aggregate female labor force participation.

Considerable evidence demonstrates that significant dispersion exists in the prices charged for seemingly homogeneous goods. This paper adopts a simple, flexible equilibrium model of search to investigate the way the market structure influences price dispersion. Using the noisy search approach, the paper demonstrates the effects of having a single large, price-leading firm with multiple outlets and a competitive fringe of small firms with one retail outlet each.

This paper incorporates assignment frictions and sector-specific training into the Roy model of occupational choice. Assignment frictions represent the extent of the market whereas differences in sector-specific training reflect worker specialization. This framework thus captures Adam Smith's idea that the extent of the market determines the division of labor. The paper demonstrates the way in which the relationship between assignment frictions and specialization affects the level and composition of human capital acquisition, aggregate output, and the distribution of income. Not surprisingly, economywide training, output, and specialization increase as the extent of the market increases. The distribution of these gains, however, is uneven. Within group or residual income, distribution does not converge monotonically as search frictions diminish. Comparisons across groups reveal that these effects can become more pronounced as average income increases. [ABSTRACT FROM AUTHOR]

This paper takes a skeptical look at a leading argument about what is causing the foreclosure crisis and what should be done to stop it. We use an economic model to focus on two key decisions: the borrower's choice to default on a mortgage and the lender's subsequent choice whether to renegotiate or modify the loan. The theoretical model and econometric analysis illustrate that unaffordable loans, defined as those with high mortgage payments relative to income at origination, are unlikely to be the main reason that borrowers decide to default. In addition, this paper provides theoretical results and empirical evidence supporting the hypothesis that the efficiency of foreclosure for investors is a more plausible explanation for the low number of modifications to date than contract frictions related to securitization agreements between servicers and investors. While investors might be foreclosing when it would be socially efficient to modify, there is little evidence to suggest they are acting against their own interests when they do so. An important implication of our analysis is that policies designed to reduce foreclosures should focus on ameliorating the immediate effects of job loss and other adverse life events rather than modifying loans to make them more affordable on a long-term basis.

This paper discusses the technological change and financial innovation that commercial banking has experienced during the past twenty-five years. The paper first describes the role of the financial system in economies and how technological change and financial innovation can improve social welfare. We then survey the literature relating to several specific financial innovations, which we define as new products or services, production processes, or organizational forms. We find that the past quarter century has been a period of substantial change in terms of banking products, services, and production technologies. Moreover, while much effort has been devoted to understanding the characteristics of users and adopters of financial innovations and the attendant welfare implications, we still know little about how and why financial innovations are initially developed.

Under the assumption of multivariate normality of asset returns, this paper presents a geometrical interpretation and the finite-sample distributions of the sample Hansen-Jagannathan (1991) bounds on the variance of admissible stochastic discount factors, with and without the nonnegativity constraint on the stochastic discount factors. In addition, since the sample Hansen-Jagannathan bounds can be very volatile, we propose a simple method to construct confidence intervals for the population Hansen-Jagannathan bounds. Finally, we show that the analytical results in the paper are robust to departures from the normality assumption. [ABSTRACT FROM AUTHOR]

This paper discusses the institutional changes needed in Europe if prompt corrective action (PCA) is to be effective in supervising and resolving cross-border banking groups. The paper identifies these changes starting with enhancements in the availability of information on banking groups' financial condition to prudential supervisors. Next, the paper considers the collective decision making by prudential supervisors with authority to make discretionary decisions within the PCA framework as soon as a bank in a cross-border banking group falls below the minimum capital standard. Finally, the paper analyzes the coordination measures that should be implemented if PCA requires the bank to be resolved. [ABSTRACT FROM AUTHOR]

Corporate social responsibility (CSR) is increasingly a core component of corporate strategy in the global economy. In recent years its importance has become even greater, primarily because of the financial scandals, investors' losses, and reputational damage to listed companies. While corporations are busy adopting and enhancing CSR practices, there is (beyond very few notable exceptions) no established empirical research on CSR's impact and relevance in the capital market. This paper investigates this issue by tracing the market reaction to corporate entry and exit from the Domini 400 Social Index, recognized as a CSR benchmark, between 1990 and 2004. The paper highlights two main findings: a significant upward trend in absolute value abnormal returns, irrespective of the type of event (for example, addition or deletion from the index), and a significant negative effect on abnormal returns after exit announcements from the Domini index. The latter effect persists even after controlling for concurring financial distress shocks and stock market seasonality. [ABSTRACT FROM AUTHOR]

The inference for hidden Markov chain models in which the structure is a multiple-equation macroeconomic model raises a number of difficulties that are not as likely to appear in smaller models. One is likely to want to allow for many states in the Markov chain without allowing the number of free parameters in the transition matrix to grow as the square of the number of states but also without losing a convenient form for the posterior distribution of the transition matrix. Calculation of marginal data densities for assessing model fit is often difficult in high-dimensional models and seems particularly difficult in these models. This paper gives a detailed explanation of methods we have found to work to overcome these difficulties. It also makes suggestions for maximizing posterior density and initiating Markov chain Monte Carlo simulations that provide some robustness against the complex shape of the likelihood in these models. These difficulties and remedies are likely to be useful generally for Bayesian inference in large time-series models. The paper includes some discussion of model specification issues that apply particularly to structural vector autoregressions with a Markov-switching structure. [ABSTRACT FROM AUTHOR]

This paper studies the cyclical pattern of ex post markups in the banking system using balance-sheet data for a large set of countries. Markups are strongly countercyclical even after controlling for financial development, banking concentration, operational costs, inflation, and simultaneity or reverse causation. The countercyclical pattern is explained by the procyclical entry of foreign banks, which occurs mostly at the wholesale level and signals the intention to spread to the retail level. My hypothesis is that wholesale entry triggers incumbents' limit-pricing strategies, which are aimed at deterring entry into retail niches and which, in turn, dampen bank markups. In the second part of the paper, I develop a general equilibrium model that accounts for these features of the data. I find that this monopolistic behavior in the intermediary financial sector increases the volatility of real variables and amplifies the business cycle. I interpret this bank-supply channel as an extension of the credit channel pioneered by Bernanke and Blinder (1988). [ABSTRACT FROM AUTHOR]

Empirical support for the long-run Fisher effect, a hypothesis that a permanent change in inflation leads to an equal change in the nominal interest rate, has been hard to come by. This paper provides a plausible explanation of why past studies have been unable to find support for the long-run Fisher effect. This paper argues that the necessary permanent change to the inflation rate following a monetary shock has not occurred in the industrialized countries of Australia, Austria, Belgium, Canada, Denmark, France, Germany, Greece, Ireland, Italy, Japan, the Netherlands, Norway, Sweden, Switzerland, the United Kingdom, and the United States. Instead, this paper shows that inflation in these countries follows a mean-reverting, fractionally integrated, long-memory process, not the nonstationary inflation process that is integrated of order one or larger found in previous studies of the Fisher effect. Applying a bivariate maximum likelihood estimator to a fractionally integrated model of inflation and the nominal interest rate, the inflation rate in all seventeen countries is found to be a highly persistent, fractionally integrated process with a positive differencing parameter significantly less than one. Hence, in the long run, inflation in these countries will be unaffected by a monetary shock, and a test of the long-run Fisher effect will be invalid and uninformative as to the truthfulness of the long-run Fisher effect hypothesis.

This paper develops a new and easily implementable necessary and sufficient condition for the exact identification of a Markov-switching structural vector autoregression (SVAR) model. The theorem applies to models with both linear and some nonlinear restrictions on the structural parameters. We also derive efficient MCMC algorithms to implement sign and long-run restrictions in Markov-switching SVARs. Using our methods, four well-known identification schemes are used to study whether monetary policy has changed in the euro area since the introduction of the European Monetary Union. We find that models restricted to only time-varying shock variances dominate the other models. We find a persistent post-1993 regime that is associated with low volatility of shocks to output, prices, and interest rates. Finally, the output effects of monetary policy shocks are small and uncertain across regimes and models. These results are robust to the four identification schemes studied in this paper.

Remittances from migrants in the United States play a major role in the Mexican economy. This paper analyzes the role that different types of social capital play in the remittances decisions of Mexican migrants. Both the decision to remit and the decision on how much to remit are analyzed. The model, based on the idea of enlightened altruism, assumes that the migrant makes his decisions based on his own well-being as well as that of his household in Mexico and his community in Mexico. Social capital is defined as the resources one gains from relationships and networks. Four different types of social capital are identified in this paper: hometown-friendship networks in the United States, family networks in the United States, other-ethnicity-based networks in the United States, and community networks in Mexico. Social capital from friendships proves to be very positively significant in both the decision to remit and how much to remit. However, for all of the observations, familial social capital is not significant in either the decision to remit or how much to remit, although familial social capital has a positive role in both tests. Other-ethnicity-based social capital negatively influences both decisions and is significant in both as well. Social capital in Mexico has a significant negative impact on the two remittance decisions. Beyond social capital, this paper provides insight into other factors that affect remittance decisions including income, bank accounts, proximity to Mexico, exchange rate, interest rate differential, community infrastructure, the number of members in the Mexican household, Mexican household consumption, and time trends. In addition, to investigate time trends further, separate regressions were run on those observations where the last migration took place before 1991 and those whose last migration occurred after 1990.

This paper studies the econometrics of computed dynamic models. Since these models generally lack a closed-form solution, economists approximate the policy functions of the agents in the model with numerical methods. But this implies that, instead of the exact likelihood function, the researcher can evaluate only an approximated likelihood associated with the approximated policy function. What are the consequences for inference of the use of approximated likelihoods? First, we show that as the approximated policy function converges to the exact policy, the approximated likelihood also converges to the exact likelihood. Second, we prove that the approximated likelihood converges at the same rate as the approximated policy function. Third, we find that the error in the approximated likelihood gets compounded with the size of the sample. Fourth, we discuss convergence of Bayesian and classical estimates. We complete the paper with three applications to document the quantitative importance of our results. [ABSTRACT FROM AUTHOR]

The paper provides a brief history of central banking institutions in the United States. Specifically, the authors highlight the role of New York banking interests in the affecting legislations affecting the creation or expiration of central banking institutions. In our previous research we have detected that New York City banking entities usually exert substantial influence on the legislation, greater than their large proportion of United States' banking resources. The authors describe how this influence affected the success or failure of central banking movements in the United States, and the authors use this evidence to support their arguments regarding the influence of New York City bankers on the legislative efforts that culminated in the creation of the Federal Reserve System. The paper argues that successful central banking movements in the United States owed much to the influence of New York City banking interests. [ABSTRACT FROM AUTHOR]

This paper rationalizes as the outcome of an optimal policy decision the pattern of reserve requirements and other macroeconomic variables in the aftermath of a bank run. The paper develops a general equilibrium model that departs from the standard small open economy (SOE) model in three dimensions: (i) capital mobility is not perfect, (ii) there exists a costly banking system, and (iii) there is an externality affecting individual banks' decisions. The results suggest that the path of reserve requirements would depend on the type of shock that the economy receives and the effect that this shock produces on the interest rate. Interestingly, the size of the risk premium will affect the reaction of the economy to the shock. It is also shown that the dynamic adjustment will be slightly different for permanent and temporary shocks, and it will also depend on the access that the economy has to foreign funds.

This paper uses a rational expectations macroeconomic model in which economic agents formulate the probability about the sustainability of the economic policy--that is, policy credibility--using current and lagged values of government expenditures and lagged values of the inflation rate. The estimation of the model is based on Hamilton's switching regime procedure. The contribution of this paper is the empirical estimation of the credibility of the stabilization program implemented in Peru in August 1990. The results of the estimation show that there are two different regimes in the government expenditure process. According to the economic agents' inferences, the stabilization program in Peru is not credible. This lack of credibility in the economic policy of the government authority explains the presence of hysteresis in currency substitution between August 1990 and June 1995. The estimation involves an expected inflation rate that includes the credibility of the economic policy in its formulation. [ABSTRACT FROM AUTHOR]

This paper extends the model of Cogley and Sargent to incorporate stochastic volatility and then estimates it for post World War II U.S. data in order to shed light on the following questions. Have aggregate time series responded through time-invariant linear impulse response functions to possibly heteroskedastic shocks? Or is it more likely that the impulse responses to shocks themselves have evolved over time because of drifting coefficients or other nonlinearities? Evidence is presented that shock variances evolved systematically over time, and so did the autoregressive coefficients of VARS. The conclusion is that much of our earlier evidence for drifting coefficients survives after we take stochastic volatility into account. This paper accumulates evidence inside an atheoretical statistical model. The patterns of time variation used revolve around whether it was bad monetary policy or bad luck that made inflation-unemployment outcomes worse in the 1970's than before or after.

Athanasios Orphanides and John C. Williams' excellent conference paper, "Inflation Scares and Forecast-Based Monetary Policy," contributes importantly to the new and rapidly growing branch of the literature on bounded rationality and learning in macroeconomics. Their paper, like many others, derives interesting and useful theoretical results that show how the introduction of bounded rationality and learning impacts on the effects of monetary policy shocks and the characteristics of optimal monetary policy rules. This note suggests that some additional empirical work--some "irrational expectations econometrics," if you will-- might serve to make these purely theoretical results seem more relevant and convincing. [ABSTRACT FROM AUTHOR]

This paper considers the implications of an important source of model mis specification for the design of monetary policy rules: the assumed manner of expectations formation. Following a considerable literature on learning, it is assumed that private agents seek to maximize their objectives subject to standard constraints and the restriction of using an econometric model to make inferences about future uncertainty. Agents do not know other agents' tastes or beliefs and therefore do not have a complete economic model with which to derive true probability laws. Because agents solve a multi-period decision problem, their actions depend on forecasts of macroeconomic conditions many periods into the future, unlike the analysis of the Bullard and Mitra (2002) and Evans and Honkapohja (2002). The central question addressed is whether the learning dynamics converge to the equilibrium predicted by rational expectations equilibrium analysis. This question is considered for several prominent instrument rules for the determination of the nominal interest rate. A key result is that a Taylor rule ensures convergence to rational expectations equilibrium, if the so-called Taylor principle is satisfied, under any of a broad class of specifications of the learning dynamics. This suggests the Taylor rule to be desirable from the point of view of eliminating instability due to self-fulfilling expectations. A companion paper, Preston (2002b), demonstrates that several policy rules argued to be desirable in the recent literature on monetary policy and learning frequently lead to the propagation of self-fulfilling expectations and hence economic instability.

The result of Benhabib, Schmitt-Grohé, and Uribe (2001) is powerful because it relies only on three rather natural conditions: the Fisher equation, the convex Taylor rule, and the lower bound of the nominal interest rate. Their result is striking because the paper reveals the peril of the active Taylor rule, which has been shown to implement the target in a stable manner under various conditions. In a related paper, Benhabib, Schmitt-Grohé, and Uribe (2002) proposed a number of policies designed to avoid the liquidity trap outcome. One is to link government's spending to the inflation rate. Subject to the intertemporal budget constraint, the government's taxation on the private sector decreases as the inflation rate drops, causing the budget of the private sector to increase. Consequent increases in aggregate demand and the price level push the economy away from the liquidity trap. This sort of fiscal policy is considered "active" in the sense that the policy can increase the government budget deficit, in contrast to the "passive" fiscal policy which is designed to maintain or lower the budget deficit.

Recent papers have analyzed how adaptive agents may converge to and escape from self-confirming equilibria. All of these papers have imputed to agents a particular prior about drifting coefficients. In the context of a model of monetary policy, this paper analyzes dynamics that govern both convergence and escape under a more general class of priors for the government. The authors characterize how the shape of the prior influences the dynamics in important ways. There are priors for which the E-stability condition is not enough to assure local convergence to a self-confirming equilibrium. Their analysis also tracks down the source of differences in the sustainability of Ramsey inflation encountered in the analyses of Sims (1988) and Chung (1990), on the one hand, and Cho, Williams, and Sargent (2002), on the other.

This paper extends the literature on net marginal tax rates created by the Social Security program by including variations in both the probability of being eligible to receive benefits and income-related life expectancy. The previous literature has found that women incur a lower net marginal tax rate because they have longer life expectancies. The results presented in this paper indicate that including variations in eligibility for benefits partially reverses this result by increasing net marginal Social Security tax rates for older women. In addition, the existing literature has shown that low-income households pay lower net marginal tax rates because the benefit formula is progressive. Including variations in life expectancy reduces, but does not eliminate, this result. This implies that differential mortality increases the net marginal Social Security tax rates incurred by low-income households. These results are important from a policy standpoint given the gender differences in poverty among the population over age sixty-five and the current debate on the future of the Social Security system.

This paper sets up a model to account for differences in total factor productivity due to differences in enforcement of contracts. Vertical specialization generates the need for intra-period credit, because final goods producers cannot pay their intermediate goods suppliers before they produce their final good. The paper shows that if there are enforcement problems, the capital distribution is skewed in the sense that intermediate goods producers operate at lower capital levels and higher marginal products of capital than final goods producers. This wedge is created by the price for intermediate goods, which is lower in economies with bad enforcement. For this reason, the high-productivity firms in the intermediate goods sector have no incentive to grow and the low-productivity firms in the final goods sector, benefiting from low intermediate goods prices, have no incentive to shrink, which causes productivity to be lower in countries with bad enforcement.

Empirical volatility studies have discovered nonstationary, long-memory dynamics in the volatility of the stock market and foreign exchange rates. This highly persistent, infinite variance-but still mean reverting-behavior is commonly found with nonparametric estimates of the fractional differencing parameter d, for financial volatility. In this paper, a fully parametric Bayesian estimator, robust to nonstationarity, is designed for the fractionally integrated, autoregressive, stochastic volatility (SV-FIAR) model. Joint estimates of the autoregressive and fractional differencing parameters of volatility are found via a Bayesian, Markov chain Monte Carlo (MCMC) sampler. Like Jensen (2004), this MCMC algorithm relies on the wavelet representation of the log-squared return series. Unlike the Fourier transform, where a time series must be a stationary process to have a spectral density function, wavelets can represent both stationary and nonstationary processes. As long as the wavelet has a sufficient number of vanishing moments, this paper's MCMC sampler will be robust to nonstationary volatility and capable of generating the posterior distribution of the autoregressive and long-memory parameters of the SV-FIAR model regardless of the value of d. Using simulated and empirical stock market return data, we find our Bayesian estimator producing reliable point estimates of the autoregressive and fractional differencing parameters with reasonable Bayesian confidence intervals for either stationary or nonstationary SV-FIAR models.

Abstract: In this paper we extend the results derived in our earlier work to develop a methodology to employ the maximum-likelihood estimation technique for the pricing of interest rate instruments. In order to price bonds and their derivative assets, researchers must identify a preference parameter in addition to the dynamics for the interest rate process. There are two approaches to obtaining estimators for both preference and dynamics parameters: (1) a two-stage approach and (2) a single-stage joint maximum-likelihood (JMLE) approach. The first approach, while tractable, suffers from serious drawbacks, primarily those relating to the use of the estimates from the first stage in estimating parameters in the second stage. In this paper, we develop the theory necessary for joint maximum-likelihood (JMLE) over the set of bond prices and the interest rate. We operationalize the theory by assuming that the error processes for all coupon bonds are mutually independent and uniformly distributed with a mean of zero. This specification is at least partially justifiable by the observation that since market prices are quoted in 1/32 of a dollar, theoretical prices must always be rounded either up or down. JML estimators can be obtained from the joint log-likelihood function by the methods of sequential quadratic programming. [ABSTRACT FROM AUTHOR]

The Supreme Court's recent decision in Kelo v. New London allows the use of eminent domain to facilitate private economic development. While the court's condition for allowing takings was highly expansive, there may be a market failure that warrants state intervention when parcels of land need to be combined for redevelopment. The collective action or strategic holdout problem associated with land assembly may limit redevelopment of older communities when one or more existing owners seek to capture a disproportionate share of the potential surplus. The problem may be compounded by landowners' uncertainty as to the true value of the expected surplus to be divided (Eckart, 1985; Strange, 1995). At the same time, developers may attempt to disguise the assemblage through the use of straw purchasers. This paper employs administrative Geographic Information System and assessor data from Seattle, Washington, to identify lots that were ultimately assembled. The paper then matches them to their pre-assembly sales. Controlling for lot and existing structure characteristics and census tract-year fixed effects, I find that land bought in the process of a successful assembly commands an 18 percent premium. Consistent with theory, this premium falls with a parcel's relative size in the assemblage. I also find some evidence that parcels toward the center of the development may command a larger premium than those at the edge, suggesting that developers retain or are perceived to retain some design flexibility.

The United States is now committed to using two relatively sophisticated approaches to measuring capital adequacy: Basel III and stress tests. This paper shows how stress testing could mitigate weaknesses in the way Basel III measures credit and interest rate risk, the way it measures bank capital, and the way it creates countercyclical capital buffers. However, this paper also emphasizes the extent to which stress tests add value will depend upon the exercise of supervisor discretion in the design of stress scenarios. Whether supervisors will use this discretion more effectively than they have used other tools in the past remains to be seen. [ABSTRACT FROM AUTHOR]

This paper examines the geographic variation in Medicare and non-Medicare health spending and finds little support for the view that most of the variation is attributable to differences in practice styles. Instead, I find that socioeconomic factors that affect the need for medical care, as well as interactions between the Medicare system, Medicaid, and private health spending, can account for most of the variation in Medicare health spending. Furthermore, I find that the health spending of the non-Medicare population is not well correlated with Medicare spending, suggesting that Medicare spending is not a good proxy for average health spending by state. Finally, there is a negative correlation between the level and growth of Medicare spending; lowspending states are not low-growth states and are thus unlikely to provide the key to curbing excess cost growth in Medicare. The paper also explores the econometric differences between controlling for health attributes at the state level (the method used in this paper) and controlling for them at the individual level (the approach used by the Dartmouth group.) I show that a state-level approach is likely to explain more of the state-level variation associated with omitted health attributes than the individuallevel approach, and argue that this econometric differences likely explains most of the difference between my results and those of the Dartmouth group. More broadly, the paper shows that the geographic variation in health spending does not provide a useful measure of the inefficiencies of our health system. States where Medicare spending is high are very different in multiple dimensions from states where Medicare spending is low, and thus it is difficult to isolate the effects of differences in health spending intensity from the effects of the differences in the underlying state characteristics. I show, for example, that the relationships between health spending, physician composition and quality are likely the result of omitted factors rather than the result of causal relationships.

Recent research has found that the dynamic properties of the New Keynesian model can be very different when the nominal interest rate is zero. Improvements in technology and reductions in the labor tax rate lower economic activity, and the size of the government purchase output multiplier can be well above one. This paper provides evidence that the focus on specifications of the New Keynesian model that produce unorthodox results in a liquidity trap may be misplaced. We show that a prototypical New Keynesian model fit to Japanese data exhibits orthodox dynamics during Japan's episode with zero interest rates. We then demonstrate that this specification is more consistent with outcomes in Japan than alternative specifications that have unorthodox properties. [ABSTRACT FROM AUTHOR]

Over the business cycle, labor's share of output is negatively but weakly correlated with output, and it lags output by about four quarters. Profit's share is strongly procyclical. It neither leads nor lags output, and its volatility is about four times that of output. Despite the importance of understanding the dynamics of income shares for understanding aggregate technology and the degree of competition in factor markets, macroeconomics lacks models that can account for these dynamics. This paper constructs a model that can replicate those facts. We introduce costly entry of firms in a model with frictional labor markets and find a link between the ability of the model to replicate income shares' dynamics and the ability of the model to amplify and propagate shocks. That link is a countercyclical real interest rate, a well-known fact in U.S. data but a feature that models of aggregate fluctuations have had difficulty achieving. [ABSTRACT FROM AUTHOR]

This paper presents a general statistical framework for estimation, testing, and comparison of asset pricing models using the unconstrained distance measure of Hansen and Jagannathan (1997). The limiting results cover both linear and nonlinear models that could be correctly specified or misspecified. We propose new pivotal specification and model comparison tests that are asymptotically chi-squared distributed. In addition, we develop modified versions of the existing model selection tests with improved finite-sample properties. Finally, we fill an important gap in the literature by providing formal tests of multiple model comparison. [ABSTRACT FROM AUTHOR]

Utilizing linked vital statistics, administrative employer, and state welfare records, the analysis in this paper investigates the determinants of a woman's intermittent labor force decision at the time of a major life event: the birth of a child. The results indicate that both direct and opportunity labor market costs of exiting the workforce figure significantly into that decision. Further, the analysis reveals the importance of including information about the mother's prebirth job when making inferences about the role various demographics play in the intermittent labor force decision.

This paper develops a model to assess the quantitative effect of entry cost and financial friction on cross-country income and total factor productivity (TFP) differences. The main focus is on the interaction between entry cost and financial friction. The model is calibrated to match establishment-level statistics for the U.S. economy assuming a perfect financial market. The quantitative analysis shows that entry costs and financial frictions together can generate a factor ten of the differences in income per capita and a factor five of the differences in TFP, and a large part of the differences are accounted for by the interaction between entry cost and financial friction. The main mechanism is that financial friction amplifies the effect of entry cost by boosting the effective entry cost. [ABSTRACT FROM AUTHOR]

This paper exploits a natural policy experiment to directly identify the crowding out effects of public transfers on the incidence and level of private transfers. The introduction of a large social security program in Taiwan is used to estimate the effect of an exogenous increase in government transfer payments to the elderly on the private transfer behavior of their adult children. Using an instrumental variables strategy that accounts for the endogeneity of receiving public transfers, the empirical results show strong evidence of crowding out on the extensive margin (the probability of providing a positive transfer) and weaker evidence of crowding out on the intensive margin (the amount of the transfer conditional on it being positive).

This paper constructs a theory of the coexistence of fixed-term and permanent employment contracts in an environment with ex ante identical workers and employers. Workers under fixed-term contracts can be dismissed at no cost while permanent employees enjoy labor protection. In a labor market characterized by search and matching frictions, firms find it optimal to discriminate by offering some workers a fixed-term contract while offering other workers a permanent contract. Match-specific quality between a worker and a firm determines the type of contract offered. We analytically characterize the firms' hiring and firing rules. Using matched employer-employee data from Canada, we estimate the wage equations from the model. The effects of firing costs on wage inequality vary dramatically depending on whether search externalities are taken into account. [ABSTRACT FROM AUTHOR]

This paper contributes to a large literature concerned with identifying the source of the widening wage gap between high school and college graduates by providing a comprehensive, multidimensional decomposition of wages across both time and educational status. Data from a multitude of sources are brought to bear on the question of the relative importance of labor market supply and demand factors in the determination of those wage differences. The results confirm the importance of investments in and use of technology, which has been the focus of most of the previous literature, but are also able to show that demand and supply factors played very different roles in the growing wage gaps of the 1980s and 1990s.

In this paper, we extend the results in Hansen (1982) regarding the asymptotic distribution of generalized method of moments (GMM) sample moment conditions. In particular, we show that the part of the scaled sample moment conditions that gives rise to degeneracy in the asymptotic normal distribution is T-consistent and has a nonstandard limiting distribution. We derive the asymptotic distribution for a given linear combination of the sample moment conditions and show how to conduct statistical inference. We demonstrate the finite-sample properties of the proposed asymptotic approximation using simulation. [ABSTRACT FROM AUTHOR]

The exact cause of the massive defaults and foreclosures in the U.S. subprime mortgage market is still unclear. This paper investigates whether a particular aspect of borrowers' financial literacy-their numerical ability-may have played a role. We measure several aspects of financial literacy and cognitive ability in a survey of subprime mortgage borrowers who took out mortgages in 2006 or 2007 and match these measures to objective data on mortgage characteristics and repayment performance. We find a large and statistically significant negative correlation between numerical ability and various measures of delinquency and default. Foreclosure starts are approximately two-thirds lower in the group with the highest measured level of numerical ability compared with the group with the lowest measured level. The result is robust to controlling for a broad set of sociodemographic variables and not driven by other aspects of cognitive ability or the characteristics of the mortgage contracts. Our results raise the possibility that limitations in certain aspects of financial literacy played an important role in the subprime mortgage crisis. [ABSTRACT FROM AUTHOR]

This paper provides empirical confirmation for Petersen and Rajan's (2002) widely accepted conjecture that information technology was the primary driver of the observed increase in small business borrower-lender distances in the United States in recent years. Using a different data source for small business loans, we show that annual increases in borrower-lender distances were slow and steady prior to 1993 (the end point in Petersen and Rajan's data) but accelerated rapidly after that. Importantly, we are able to assign at least half of this acceleration to the adoption of credit scoring technologies by the lending banks. Our tests also reveal strong statistical associations between lending distances and borrower characteristics, lender characteristics, market conditions, regulatory constraints, moral hazard incentives, and principal-agent incentives.

Collateral is a widely used, but not well understood, debt-contracting feature. Two broad strands of theoretical literature explain collateral as arising from the existence of either ex ante private information or ex post incentive problems between borrowers and lenders. However, the extant empirical literature has been unable to isolate each of these effects. This paper attempts to do so using a credit registry that is unique in that it allows the researcher to have access to some private information about borrower risk that is unobserved by the lender. The data also include public information about borrower risk, loan contract terms, and ex post performance for both secured and unsecured loans. The results suggest that the ex post theories of collateral are empirically dominant although the ex ante theories are also valid for customers with short borrower-lender relationships that are relatively unknown to the lender.

In this paper, we first introduce investment-specific technology (IST) shocks into an otherwise standard international real business cycle model and show that a thoughtful calibration of them along the lines of Raffo (2009) successfully addresses several of the existing puzzles in the literature. In particular, we obtain a negative correlation of relative consumption and the terms of trade (Backus-Smith puzzle), as well as a more volatile real exchange rate, and cross-country output correlations that are higher than consumption correlations (price and quantity puzzles). Then we use data from the Organisation for Economic Co-operation and Development for the relative price of investment to build and estimate these IST processes across the United States and a "rest of the world" aggregate, showing that they are cointegrated and well represented by a vector error-correction model. Finally, we demonstrate that, when we fit such estimated IST processes into the model, the shocks are actually powerless to explain any of the existing puzzles. [ABSTRACT FROM AUTHOR]

Previous studies on financial frictions have been unable to establish the empirical significance of credit constraints in macroeconomic fluctuations. This paper argues that the muted impact of credit constraints stems from the absence of a mechanism to explain the observed persistent comovements between housing prices and business investment. We develop such a mechanism by incorporating two key features into a dynamic stochastic general equilibrium model: We identify shocks that shift the demand for collateral assets and allow productive agents to be credit-constrained. A combination of these two features enables our model to successfully generate an empirically important mechanism that amplifies and propagates macroeconomic fluctuations through credit constraints. The degree of amplification provided by credit constraints seems to depend crucially on the parameters of the economy. This result sets up a clear challenge for future work: to demonstrate, in a carefully calibrated model environment, that the amplification and propagation possible by credit constraints are quantitatively significant (Kocherlakota 2000).

This paper studies an optimal fiscal policy problem of Lucas and Stokey (1983) but in a situation in which the representative agent's distrust of the probability model for government expenditures puts model uncertainty premia into history-contingent prices. This situation gives rise to a motive for expectation management that is absent within rational expectations and a novel incentive for the planner to smooth the shadow value of the agent's subjective beliefs to manipulate the equilibrium price of government debt. Unlike the Lucas and Stokey (1983) model, the optimal allocation, tax rate, and debt become history dependent despite complete markets and Markov government expenditures. [ABSTRACT FROM AUTHOR]

This paper revisits the no-recall assumption in job search models with take-it-or-leave-it offers. Workers who can recall previously encountered potential employers in order to engage them in Bertrand bidding have a distinct advantage over workers without such attachments. Firms account for this difference when hiring a worker. When a worker first meets a firm, the firm offers the worker a sufficient share of the match rents to avoid a bidding war in the future. The pair share the gains to trade. In this case, the Diamond paradox no longer holds. [ABSTRACT FROM AUTHOR]

This paper examines wage dispersion and wage dynamics in a stock-flow matching economy with on-the-job search. Under stock-flow matching, job seekers immediately become fully informed about the stock of viable vacancies. If only one option is available, monopsony wages result. With more than one firm bidding, Bertrand wages arise. The initial and expected threat of competition determines the evolution of wages and thereby introduces a novel way of understanding wage differences among similar workers. The resulting wage distribution has an interior mode and prominent, well-behaved tails. The model also generates job-to-job transitions with both wage cuts and jumps. [ABSTRACT FROM AUTHOR]

We explore how a relatively small amount of heterogeneous securities created turmoil in financial markets in much of the world in 2007 and 2008. The drivers of the financial turmoil and the financial crisis of 2008 were heterogeneous securities that were hard to value. These securities created concerns about counterparty risk and ultimately created substantial uncertainty. The problems spread in ways that were hard to see in advance. The run on prime money market funds in September 2008 and the effects on commercial paper were an important aspect of the crisis itself and are discussed in some detail. [ABSTRACT FROM AUTHOR]
