We offer a critique of the popular notion that the log-change of the real exchange rate equals the log-difference between the IMRSs of economically distinct agents in two economies. Contrary to existing claims, we show that this interpretation does not hold true in reduced-form SDF models that...

Recent theories of exchange rate determination have emphasized limited UIP arbitrage by international financial institutions. New regulations since 2008 have also lead to imperfect CIP arbitrage. We show that under limited CIP arbitrage the exchange rate and CIP deviation are jointly determined...

The primary aim of this study is to analyze the impact of imperfections in capital markets on individuals' lifetime allocation plans and the resulting implications for income distribution. The model builds upon Samuelson's overlapping generation model with human capital and bequest motives...

The object of this paper is to examine the importance of capital market assumptions. A special continuous-time model is developed in sections II-IV which is applicable to the perfect capital market case. It can also be used when there is no capital market at all (section IV). For 'reasonable'...

This paper studies how capital market imperfections affect the welfare effects of forming a currency union. The analysis considers a bank-only world where intermediaries compete in Cournot fashion and monitoring and state verification are costly. The first part determines the credit market...

Typical models of bankruptcy and collateral rely on incomplete asset markets. In fact, bankruptcy and collateral add contingencies to asset markets. In some models, these contingencies can be used by consumers to achieve the same equilibrium allocations as in models with complete markets. In...

The existence of a natural resource curse has been a longstanding theme in the economic literature and in policy discussions. We propose an alternative mechanism and study its policy implications. The mechanism is based on the interaction between two building blocks: specialization in...

This paper studies an Overlapping Generations model with stochastic production and incomplete markets to assess whether the introduction of an unfunded social security system can lead to a Pareto improvement. When returns to capital and wages are imperfectly correlated, the consumption variance...

The small open economy model with incomplete asset markets features a steady state that depends on initial conditions and equilibrium dynamics that possess a random walk component. A number of modifications to the standard model have been proposed to induce stationarity. This paper presents a...
