This article presents reliable data on the life expectancy of the monks of Durham Priory between 1395 and 1529. The number of years that monks survived in this northern monastery plunged precipitously in the second half of the fifteenth century before staging a partial recovery in the early sixteenth. The experience of Durham monks mirrors the scale, direction, and timing of the data already produced for the monks of Canterbury and Westminster. While the precise relationship between monastic mortality and that of the population at large remains difficult to determine, there can be no doubt that the symmetry that has been established between mortality in three monasteries located in different parts of the country has important implications for our understanding of the demographic history of late medieval England. 相似文献

What Works at Work: Overview and Assessment 总被引:4,自引:0,他引:4
This article discusses why it is difficult to measure the effects of management practices on organizational performance. In spite of these difficulties, a collage of evidence suggests that innovative workplace practices can increase performance, primarily through the use of systems of related practices that enhance worker participation, make work design less rigid, and decentralize managerial tasks. A majority of U.S. businesses have adopted some innovative work practices. However, only a small percentage of businesses have adopted a full system of innovative practices. We outline several constraints on the diffusion of new work practices, and suggest directions for future research 相似文献

Some justify the law enforcement emphasis on controlling illicit drug markets by contending that drug users attempting to finance their habits often are responsible for property crime. Yet, in Florida at least, the increased effort to control drug markets has been accompanied by increasing property crime. The fact is that law enforcement resources are scarce, and many resources now being devoted to enforcing drug laws have been shifted away from enforcing laws pertaining to other crimes. This has reduced deterrence for property crime and, as a result, such crime has increased. Thus, the resource reallocations accompanying strong drug law enforcement lead to more property crime. 相似文献

The shift from feudalism to industrial capitalism was generally accompanied by an increase in social mobility. We ask whether such an increase has occurred in a developing nation currently undergoing rapid industrialization, Indonesia. It has, at least as measured by a declining intergenerational correlation of education. To highlight the effects of economic growth on intergenerational mobility, we contrast Indonesia's experience with that of Bangladesh, where industrialization has proceeded more slowly and the correlation between parents’ and children's education has been roughly stable. We also examine potential causal channels for the rising educational mobility we find in Indonesia, but cannot identify specific pathways related to above‐average school building or rapid industrialization in a region. 相似文献

The agency relationship of corporate insiders and bondholders is modeled as a dynamic game with asymmetric information. The incentive effect of risky debt on the investment policy of a levered firm is studied in this context. In a sequential equilibrium of the model, a concept of reputation arises endogenously resulting in a partial resolution of the classic agency problem of underinvestment. The incentive of the firm to underinvest is curtailed by anticipation of favorable rating of its bonds by the market. This anticipated pricing of debt is consistent with rational expectations pricing by a competitive bond market and is realized in equilibrium. Some empirical implications of the model for bond rating, debt covenants, and bond price response to investment announcements are explored. 相似文献

Army recruiting is sensitive to fluctuations in labor market conditions. Declines in unemployment over the past several years have led to decreases in the number and quality of enlistments. The Army has several discretionary policy tools that it can use to reduce cyclical variations in recruiting. However, budget constraints and other external requirements often limit the flexibility of these tools. More recently, the recruiting outlook turned favorable for the Army, primarily due to planned reductions in end strength. These reductions imply a 20 to 30 percent drop in total enlistment requirements over the next several years compared with 1989 levels. The danger is that dramatic budget cuts will impair the manpower quality goals of recruiting. Recruiting cuts alone should not be the only means of meeting end-strength reductions to 1995. 相似文献

This paper shows that the spread between the 3–month Treasury bill and the federal funds rate has significant predictive power for the future change in the federal funds rate during the volatile nonborrowed reserves operating regime, but it has less and no predictive power during the borrowed reserves regime and the federal funds targeting regime, respectively. These findings suggest that Treasury bill rates forecast future federal funds rates most accurately when the Federal Reserve follows a well-defined rule that does not smooth the impact of shocks on the federal funds rate. 相似文献

This paper presents an aging analysis of 741 high yield bonds and finds default, exchange, and call percentages substantially higher than reported in earlier studies. By December 31, 1988, cumulative defaults are 34 percent for bonds issued in 1977 and 1978 and range from 19 to 27 percent for issue years 1979–1983 and from 3 to 9 percent for issue years 1984–1986. Exchanges are also a significant factor although they often are followed by default. Moreover, a significant percentage of high yield debt, 26–47 percent for 1977–1982, has been called. By December 31, 1988, approximately one third of the bonds issued in 1977–1982 has defaulted or been exchanged, and an additional one third had been called. On average, only 28 percent of these issues are still outstanding. There is no evidence that early results for more recent issue years differ markedly from issue years 1977 to 1982. 相似文献
