We analyze the effects of money injections on interest rates and exchange rates when agents must pay a Baumol-Tobin-style fixed cost to exchange bonds and money. Asset markets are endogenously segmented because this fixed cost leads agents to trade bonds and money infrequently. When the...

This paper analyses the effects of open market operations on interest rates in a model in which agents must pay a fixed cost to exchange assets and cash. Asset markets are endogenously segmented in that some agents choose to pay the fixed cost and some do not. When the fixed cost is zero, the...

Under mild assumptions, the data indicate that fluctuations in nominal interest rate differentials across currencies are primarily fluctuations in time-varying risk. This finding is an immediate implication of the fact that exchange rates are roughly random walks. If most fluctuations in...

Since 1989, creditor countries have provided debt relief to developing countries worth more than 100 billion US dollars. Prominent lobby groups are campaigning for a further 400 billion US dollars in debt relief to be provided in the near future. How much could developing country’s gain...

From the end of the SecondWorldWar to the beginning of the Twenty-First Century, per-capita GDP in the economies of East Asia grew almost three times as fast as in the economies of Latin America. Specifically, in 1950, the economies of the Asian Tigers (Japan, South Korea, Singapore and Taiwan)...

We develop a macroeconomic model with physical and human capital, human capital risk, and limited contract enforcement. We show analytically that young (high-return) households are the most exposed to human capital risk and are also the least insured. We document this risk-insurance pattern in...
