Can the Life Insurance Market Provide Evidence for a Bequest Motive?

Using U.K. microeconomic data, we analyze the empirical determinants of participation in the life insurance market. We find that term insurance demand is positively correlated with measures of bequest motives like being married, having children, and/or subjective measures of strong bequest motives. We then show that a life‐cycle model of life insurance demand, saving, and portfolio choice can rationalize quantitatively the data in the presence of a bequest motive. These findings provide evidence supporting the presence of a bequest motive.     

Thousands of models,one story: Current account imbalances in the global economy

The global financial crisis has led to a revival of the empirical literature on current account imbalances. This paper contributes to that literature by investigating the importance of evaluating model and parameter uncertainty prior to reaching any firm conclusion. We explore three alternative econometric strategies: examining all models, selecting a few, and combining them all. Out of thousands (or indeed millions) of models a story emerges. The chance that current accounts were aligned with fundamentals prior to the financial crisis appears to be minimal.     

Demographic change, human capital and welfare

Projected demographic changes in the U.S. will reduce the share of the working-age population. Analyses based on standard OLG models predict that these changes will increase the capital-labor ratio. Hence, rates of return to capital decrease and wages increase, which has adverse welfare consequences for current cohorts who will be retired when the rate of return is low. This paper argues that adding endogenous human capital accumulation to the standard model dampens these forces. We find that this adjustment channel is quantitatively important. The standard model with exogenous human capital predicts welfare losses up to 12.5% (5.6%) of lifetime consumption, when contribution (replacement) rates to the pension system are kept constant. These numbers reduce to approximately 8.7% (4.4%) when human capital can endogenously adjust.     

Cross-border banking,credit access,and the financial crisis

We study the sensitivity of credit supply to bank financial conditions in 16 emerging European countries before and during the financial crisis. We use survey data on 10,701 applicant and non-applicant firms that enable us to disentangle effects driven by positive and negative shocks to the banking system from demand shocks that may vary across lenders. We find strong evidence that firms' access to credit was affected by changes in the financial conditions of their banks. During the crisis firms were more credit constrained if they were dealing with banks that experienced a decline in equity and Tier 1 capital, as well as losses on financial assets. We also find that access to credit reflects the balance sheet conditions of foreign parent banks. The effect of positive and negative shocks to a bank is greater for riskier firms and firms with fewer tangible assets.     

On existence of optimal programs: The RSS model without concavity assumptions on felicities

In the context of a model due to Robinson, Solow and Srinivasan (the RSS model) with time-dependent felicity functions that are not necessarily concave, we report a theorem on the existence of optimal programs. An extended introduction places our theorem in the context of previous work on the existence question.     

Financial constraints and occupational choice in Thai villages

Financial constraints and entrepreneurship are key factors affecting economic performance in developing countries. I formulate and solve a model of occupational choice with moral hazard under three alternative financial market environments: savings only, borrowing and lending with default and moral hazard constrained insurance. I use computationally efficient techniques based on mechanism design, genetic algorithms and maximum likelihood to estimate and statistically test these models of financial constraints. Using occupational choice data from Thai villages I find evidence that the saving only regime is rejected in favor of regimes allowing for borrowing and/or insurance, especially in higher-wealth data stratifications. A direct test between the borrowing and insurance regimes reveals that neither can be rejected in favor of the other. Allowing ex-ante lotteries over wealth improves the explanatory power of the model. I also find evidence for differences in the best fitting regimes by region, wealth, and access to formal credit.     

And then current accounts (over)adjusted

The global financial turmoil has led to an unprecedented current account adjustment in central and eastern Europe. This article investigates this issue by revisiting two approaches. The first is the current account literature based on panel econometric techniques. This article adds to the literature by showing that, although there is a large degree of parameter uncertainty associated with the choice of determinants, the implied current account benchmarks for central and eastern Europe are in a narrow range. The second approach is the external sustainability framework where we extend the analysis to take into account the importance of FDI financing. We find that both approaches point to similar conclusions on which countries were in need of a current account adjustment in central and eastern Europe in 2007. The turmoil in financial markets in 2008 set this adjustment in motion.     

Privatization and Corporate Governance: Principles, Evidence, and Future Challenges

Unless developing countries embrace a corporate governance perspective,privatization is unlikely to provide the benefits of improvedperformance with accountability. This article introduces theconcept of governance chains that can constrain the grabbinghands of public and private actors by providing informationand accountability mechanisms to help investors monitor managers.Empirical data on established firms from 49 countries provideestimates of the relative importance and strength of privateand formal chains of governance. The framework and empiricalbenchmarks help explain the outcomes of past privatizationsand suggest certain steps that governments can pursue to besure to get the most out of future privatization activity.      

Estimating the causal effect of beliefs on contributions in repeated public good games

We use instrumental variables for estimating the causal effect of beliefs on contributions in repeated public good games. The effect is about half as large as suggested by ordinary least squares. Thus, we present evidence that beliefs have a causal effect on contributions, but also that beliefs are endogenous. We compare the causal, belief-based model of contributions to alternative models based on matching the previous contributions of others and responding to one’s deviation from the average in the previous round. The causal, belief-based model performs well, indicating that beliefs have a central role in determining contributions.
