This paper analyzes the stochastic inventory control problem when the demand distribution is not known. In contrast to previous Bayesian inventory models, this paper adopts a non-parametric Bayesian approach in which the firm’s prior information is characterized by a Dirichlet process prior. This provides considerable freedom in the specification of prior information about demand and it permits the accommodation of fixed order costs. As information on the demand distribution accumulates, optimal history-dependent (s,S) rules are shown to converge to an (s,S) rule that is optimal when the underlying demand distribution is known.

This paper examines financial market comovements across European transition economies and compares their experience to that of their regions. Correlations in monthly indices of exchange market pressures can partly be explained by direct trade linkages, but not by measures of other fundamentals. Higher-frequency data during three crisis periods reveals the presence of structural breaks in the relationship between exchange-, but not stock markets. While the reaction of markets during the Asian and Czech crises is muted, the pattern of high-frequency spillovers during the Russian crisis looks very similar to that observed in other regions during turbulent times.

This paper analyzes empirically the recent Asian financial crisis using high frequency data of exchange rates and stock indices of the Philippines and Thailand. Utilizing standard time-series techniques, this study confirms that there is evidence that developments in some sectoral indices—including those of banking and financial sectors—seem to have caused upward pressure on exchange rates. A correlation between some of these variables is also found to be strong across countries in the crisis period, thereby confirming the importance of the linkages between financial markets as a transmission channel of the Thai crisis to the Philippines.

This paper studies the correlation between output growth and lagged stock returns in a panel of emerging market economies and advanced economies. It finds that the correlation is as strong in emerging market economies as in advanced economies. Asset prices therefore contain valuable information to forecast output also in emerging market economies. Moreover, the paper finds that the strength of the correlation between output growth and lagged stock returns is significantly related to a number of stock market characteristics, such as the number of listed domestic companies and initial public offerings and, especially, a high market capitalization to GDP ratio and English legal origin.

This paper explores the behavior of emerging market mutual funds using a novel database covering the holdings of individual funds over the period January 1996 to March 1999. An examination of individual crises shows that, on average, funds withdrew money one month prior to the events. The degree of herding among funds is statistically significant, but moderate. Herding is more widespread among open-ended funds than among closed-end funds, but not more prevalent during crises than during tranquil times. Funds tend to follow momentum strategies, selling past losers and buying past winners, but their overall behavior is more complex than often suggested.

Policymakers often express concern that herding by financial market participants destabilizes markets and increases the fragility of the financial system. This paper provides an overview of the recent theoretical and empirical research on herd behavior in financial markets. It addresses the following questions: What precisely do we mean by herding? What could be the causes of herd behavior? What success have existing studies had in identifying such behavior? And what effect does herding have on financial markets?.

Recent years have witnessed a change in the composition of capital flows to developing countries, and FDI and equity flows have been playing an increasing role. In this paper we discuss the challenges for international macroeconomics that these developments pose and characterize stylized facts associated with the structure of external liabilities in developing countries, focusing in particular on FDI and equity stocks.

This paper explores whether changes in the age distribution have significant effects on financial markets that are rational and forward-looking. It presents an overlapping generations model in which agents make a portfolio decision over stocks and bonds when saving for retirement- Using the model to simulate a baby boom-baby bust demonstrates that returns to baby boomers will be substantially below returns to earlier generations, even when markets are rational and forward-looking. This result is important because the current debate over how to reform pay-as-you-go pension systems often takes historical returns on financial assets—and on the equity premium—as given.

This paper evaluates the potential role of mandatory subordinated debt (MSD) in enhancing market discipline in emerging markets. The conceptual merits and key preconditions of MSD are first reviewed. Then, the extent to which emerging markets satisfy these preconditions—among them the monitorability of bank assets, the presence of nonbank financial investors, and liquid and “clean” capital markets—are evaluated. We find that emerging markets do not satisfy the preconditions for the successful implementation of a MSD policy. Therefore, efforts to enhance market discipline should first focus on satisfying these preconditions and improving the overall incentive environment and market infrastructure.

Large stocks of U.S. dollars and other hard currencies circulate in the transition economies, in Latin America, and in other countries that have experienced macroeconomic mismanagement. Using a monetary model that combines the legal restrictions and crime-theoretic traditions, this paper demonstrates how leaky exchange controls lead to currency substitution and progressive dollarization. The paper also analyzes the impact of dollarization on the ability of governments to earn seigniorage, the dynamics of dollarization in a growing economy, and the central role of expectations—specifically, confidence in the domestic currency—in determining the extent of dollarization and, potentially, in reversing it.
