Conditioning manager alphas on economic information: another look at the persistence of performance

This article presents evidence on persistence in the relativeinvestment performance of large, institutional equity managers.Similar to existing evidence for mutual funds, we find persistentperformance concentrated in the managers with poor prior-periodperformance measures. A conditional approach, using time-varyingmeasures of risk and abnormal performance, is better able todetect this persistence and to predict the future performanceof the funds than are traditional methods.     

Sterilization, Monetary Policy, and Global Financial Integration

This paper investigates the changing pattern and efficacy of sterilization within emerging market countries as they liberalize markets and integrate with the world economy. We estimate the marginal propensity to sterilize foreign asset accumulation associated with net balance of payments inflows, across countries, and over time. We find that the extent of sterilization of foreign reserve inflows has risen in recent years to varying degrees in Asia as well as in Latin America, consistent with greater concerns about the potential inflationary impact of reserve inflows. We also find that sterilization depends on the composition of balance of payments inflows.     

US domestic airline alliances: does the national welfare impact turn on strategic international gains?

The six largest U.S. airlines announced in the beginning of 1998 the formation of three domestic alliances, but the size and scope of these alliances spurred significant public interest concerns. GAO analysis suggests a rough equivalence between the domestic costs and benefits of alliances, yet the international competitive effects have not been considered. I argue that the national welfare merits of domestic airline alliances turn on positive international competitive effects. Empirical tests - run on comprehensive panel data covering the international airline markets among 21 nations over the 1983–1992 period - support domestic market concentration resulting in strategic international gains; hence, domestic airline alliances likely improve national welfare.     

The hospital: how will it survive?

The federal government is under pressure to implement and enforce a program to provide economic and social relief from the rapidly escalating health care costs which now consume 8.5% of the Gross National Product. Glick predicts that within the next twenty years, the character of health care institutions will be reshaped and only the most adaptable hospitals, health maintenance organizations and health-related governmental organizations will survive. He urges hospitals to develop appropriate strategies to deal with the problems of cost-containment, state-operated cost review and control agencies, and the competition for limited health care resources. The author warns the health care industry that if it does not adjust to these changes, it runs the risk of becoming heavily rgulated. It is suggested that health care institutions be integrated into comprehensive health care systems and the article includes a model for assigning patients to medical care facilities on a regional basis. Glick forecasts that hospitals will enter into a competition for survival, resulting in mergers of some and the closing of others. He believes that as the number of health care institutions decreases, the remaining ones will become more specialized and geographically dispersed.     

Determinants of HIV Knowledge and Condom Use among Women in Madagascar: An Analysis Using Matched Household and Community Data

Abstract: We estimate the determinants of HIV/AIDS knowledge and related behavior (use of condoms) among women in Madagascar, a country where prevalence remains low but conditions are ripe for a rapid increase in infections. In both rural and urban areas, more educated and wealthier women are more likely to know about means of preventing infection, less likely to have misconceptions about transmission, and more likely to use condoms. Community factors such as availability of health centers and access to roads also are associated with greater HIV knowledge. However, most of the large rural‐urban difference in mean knowledge is due not to location per se but to differences in schooling and wealth; rather than simply being geographically targeted, AIDS education efforts must be designed to target and be understood by uneducated and poor subpopulations.     

Productivity, tradability, and the long-run price puzzle

Long-run cross-country price data exhibit a puzzle. Today, richer countries exhibit higher price levels than poorer countries, a stylized fact usually attributed to the Balassa-Samuelson (BS) effect. But looking back 50 years, this effect virtually disappears from the data. What is often assumed to be a universal property is actually quite specific to recent times, emerging a half century ago and growing steadily over time. What might potentially explain this historical pattern? We develop an updated BS model inspired by recent developments in trade theory, where a continuum of goods are differentiated by productivity, and where tradability is endogenously determined. Firms experiencing productivity gains are more likely to become tradable and crowd out firms not experiencing productivity gains. As a result the usual BS assumption—that productivity gains be concentrated in the traded goods sector—emerges endogenously, and the BS effect on relative price levels likewise evolves gradually over time.
