Principal-agent models take outside options, determining participation and incentive constraints, as given. We construct a general equilibrium model where workers' reservation wages and the maximum punishment acceptable before workers quit are instead determined endogenously. We simultaneously...

This paper develops simple geometric methods for analyzing dynamic behavior in models with intertemporally dependent consumer tastes. Since the preferences studied do not assume time-additivity, they allow the marginal utility of consumption on a given date to vary with consumption on other...

The paper develops a simple stochastic new open economy macroeconomic model based on sticky nominal wages. Explicit solution of the wage-setting problem under uncertainty allows one to analyze the effects of the monetary regime on welfare, expected output, and the expected terms of trade....

Policy rules that are consistent with inflation targeting are examined in a small macroeconomic model of the US economy. We compare the properties and outcomes of explicit instrument rules' as well as targeting rules.' The latter, which imply implicit instrument rules, may be closer to actual...

We propose that analysis of purchasing power parity (PPP) and the law of one price (LOOP) should explicitly take into account the possibility of commodity points' thresholds delineating a region of no central tendency among relative prices, possibly due to lack of perfect arbitrage in the...

This note tests the hypothesis that nominal interest differentials between similar assets denominated in different currencies can be explained entirely by the expected change in the exchange rate over the holding period. This proposition, often called the "Fisher open" hypothesis or the...

This paper surveys the decline in real interest rates in advanced and emerging economies over the past several decades, linking that process to a range of global factors that have operated with different force in different periods. The paper argues that estimates of long-run equilibrium real...

The elasticity of substitution between goods from different countries---the Armington elasticity---is important for many questions in international economics, but its magnitude is subject to debate: the "macro" elasticity between home and import goods is often found to be smaller than the...

The analysis of the effects ofcapital gains taxation requires a careful modelling both of the details of the tax code and the imperfections in the capital market. Under the standard assumptions concerning perfect capital marketsand under the standard idealizations of the tax code, there are...

"How does the lack of legitimacy of property rights affect the dynamics of the creation of the rule of law? We investigate the demand for the rule of law in post-Communist economies after privatization under the assumption that theft is possible, that those who have "stolen" assets cannot be...
