This paper outlines a way to estimate transition matrices for use in credit risk modeling with a decades-old methodology that uses aggregate proportions data. This methodology is ideal for credit-risk applications where there is a paucity of data on changes in credit quality, especially at an...

This paper assesses the extent to which crashes in emerging market currencies are predictable using simple logit models based on lagged macroeconomic and financial data. To evaluate our model, we calculate trading strategies in which an investor goes long or short in the currency depending on...

There is strong evidence that interest rates and bond yield movements exhibit both stochastic volatility and unanticipated jumps. The presence of frequent jumps makes it natural to ask whether there is a premium for jump risk embedded in observed bond yields. This paper identifies a class of...

This paper analyzes broad money demand (M2) in Guyana from January 1990 to September 1999; a period marked by deep transformations aimed at shifting Guyana from a centralized to a market economy. The paper develops a stable error-correction model based on a long-run cointegrating vector of money...

An influential theoretical literature has observed that economic diversification can reduce risk and increase financial development. But causality operates in both directions, as a well functioning financial system can enable a society to invest in more productive but risky projects, thereby...

Using the ARFIMA-FIGARCH model, this paper studies the efficiency of the Japanese equity market by examining the statistical properties of the return and volatility of the Nikkei 225. It shows that both follow a long range dependence, which stands against the efficient market hypothesis (EMH)....

This paper compares two alternative measures of technology differences across industrial countries during 1970-92: one measures differences in labor productivity (the Ricardian measure), and the other differences in total factor productivity (the Hicksian measure). The distinction between the...

We estimate tax multipliers in a "Blanchard-Yaari" consumption model where Ricardian equivalence is broken because the private sector discounts the future at a faster rate than the real rate of interest. The model fits U.S. data since 1955 extremely well-entailing a discount wedge of around 20...

Government spending plays a critical role in protecting and enforcing rights and civil liberties. Empirical evidence for a sample of industrial and developing countries shows that government expenditures on defense, law and order, social security, education, and health care are associated with...

This paper provides a model on how altruism, "attachment" to the home country, and portfolio diversification may act as potential motives behind workers' remittances. It shows that the level of workers' remittances depends on how great are their degrees of altruism and "attachment" to their home...
