We investigate ex-ante efficient contracts in an environment in which implementation is costless. In this environment, standard debt contracts will typically not be optimal. Optimal contracts may involve defaults, even in states in which the borrower is fully able to repay. We then examine the welfare costs of arbitrarily restricting the set of feasible contracts to standard debt contracts. When model parameters are calibrated to realistic values, the welfare loss from exogenously imposing this restriction is extremely small. Thus, if the implementation costs are actually nontrivial (as seems likely), standard debt contracts will be (very close to) optimal.

Creator: Ostroy, Joseph M. and Potter, Simon M. Series: Finance, fluctuations, and development Abstract:
We formulate a representative consumer model of intertemporal resource reallocation in which fluctuations in equity prices contribute to the smoothing of consumption flows. Features of the model include (a) an incompletely observable stochastic process of productivity shocks leading to fluctuating confidence of beliefs and (b) technologies involving commitments of a resource good. These features are exploited to show that (1) equities are not a representative form of total wealth and (2) the valuation of currently active firms is not representative of the valuation of all firms. We examine the implications of (1) and (2) to argue that empirical findings for the volatility and 'value shortfall' of equity prices may be consistent with a frictionless representative consumer model having a low degree of risk-aversion. Simulation of a calibrated version of the model for a risk-neutral consumer shows that when the 'data' is analyzed according to current econometric procedures, it is found to exhibit volatility of the same order of magnitude as that found in the actual data, although the model contains no excess volatility.

Creator: Ligon, Ethan., Thomas, Jonathan P., and Worrall, Tim. Series: Endogenous incompleteness Abstract:
This paper studies efficient insurance arrangements in village economies when there is complete information but limited commitment. Commitment is limited because only limited penalties can be imposed on households which renege on their promises. Any efficient insurance arrangement must therefore take into account the fact that households will renege if the benefits from doing so outweigh the costs. We study a general model which admits aggregate and idiosyncratic risk as well as serial correlation of incomes. It is shown that in the case of two households and no storage the efficient insurance arrangement is characterized by a simple updating rule. An example illustrates the similarity of the efficient arrangement to a simple debt contract with occasional debt forgiveness. The model is then extended to multiple households and a simple storage technology. We use data from the ICRISAT survey of three villages in southern India to test the theory against three alternative models: autarky, full insurance, and a static model of limited commitment due to Coate and Ravallion (1993). Overall, the model we develop does a significantly better job of explaining the data than does any of these alternatives.

Creator: Bergoeing, Raphael., Hernando, Andrés., and Repetto, Andrea. Series: Advances in dynamic economics Abstract:
We estimate the effects of policy distortions on aggregate productivity. Based on a model of plant production and productivity uncertainty and heterogeneity, and using Chilean manufacturing data, we focus on the effect of taxation on the exit behavior of plants. We find that taxes do distort the liquidation decisions of firms, suggesting that policy distortions reduce the extent to which factors are reallocated towards the most productive plants. Our results have important consequences for growth and development, as policies that alter the measure of plants that operate in equilibrium change the short-run response of output to exogenous shocks and the long run level of aggregate TFP. In particular, we find that the amount of productivity lost due to excessive plant shutdowns are very large.

This paper examines data on point and probabilistic forecasts of inflation from the Survey of Professional Forecasters. We use this data to evaluate current strategies for the empirical modeling of forecast behavior. In particular, the analysis principally focuses on the relationship between ex post forecast errors and ex ante measures of uncertainty in order to assess the reliability of using proxies based on predictive accuracy to describe changes in predictive confidence. After we adjust the data to account for certain features in the conduct and construct of the survey, we find a significant and robust correlation between observed heteroskedasticity in the consensus forecast errors and forecast uncertainty. We also document that significant compositional effects are present in the data that are economically important in the case of forecast uncertainty, and may be related to differences in respondents' access to information.
