THE EFFECTS OF COMPANY TRAINING,FURTHER EDUCATION AND THE YOUTH TRAINING SCHEME ON THE EARNINGS OF YOUNG EMPLOYEES* 总被引:1,自引:0,他引:1

Abstract This paper provides evidence on the impact of company training, of post-compulsory education and of the UK Youth Training Scheme in the late 1980's on the earnings of 21-year-old employees in England and Wales. Earnings equations are estimated for each of seven groups of employees who have followed alternative routes from compulsory education into employment, allowing for selectivity into these routes. There are several findings, including: both high parental social class and better school qualifications help to channel people into higher status routes, while high local unemployment has the opposite effect; participation in company training in long spells substantially raises wages but short spells do not; YTS participation fails to raise, and possibly substantially lowers, wages even three years after graduation compared to those who left school at 16 and went to work and received no training; there is weak evidence that, even for those that do not enter higher education, it is better to stay on at school after 16 than go into YTS. 相似文献

An examination of the ethical perceptions of business students using Macobby's head/heart traits and a comparison to earlier studies of managers, accountants, and business students is made. The data were collected at three universities that are similar in size, enrollment and degree programs within the College of Business. Results indicate that present day business students are no less ethically inclined than are their business counterparts in previous eras. In general head traits dominated over heart traits, an indication that business schools continued to do a good job emphasizing and developing analytical skills but a poor job of developing the qualities of the heart that are generally associated with ethical behavior. The implications of these findings are discussed. 相似文献

Models for which the MLE and the conditional MLE coincide 总被引:1,自引:0,他引:1
The MLE, CMLE and MMLE coincide in a linear regression model with fixed individual effects. In this case, there is no incidental parameters problem and the MLE is consistent. The equivalence of these estimators is important because CMLE=MLE implies both the consistency of the MLE and the efficiency of the CMLE. In general, we cannot expect to find a CMLE or MMLE, since there may be no fixed-dimension sufficient statistic for the effects, nor an appropriate transformation of the data whose distribution does not depend on the effects. However, we show that the MLE, CMLE and MMLE do coincide in systems of seemingly unrelated regressions and in systems of simultaneous equations. We establish this result for systems in which (exogenous) variables in addition to (or other than) the intercept may have coefficients which vary over individuals, provided that the set of such variables is the same in every equation.The financial support of the National Science Foundation is gratefully acknowledged. 相似文献

This paper presents the basic analytics of a debt/equity swap and illustrates the concept with a detailed example of American Express Bank's swap transactions that began in 1986 and have resulted in construction of seven hotels in Mexico during the course of the swap agreement. The economics of the swap are presented from the lending bank's view, from the foreign direct investor's view, and from the borrowing country's view. It is concluded that: swaps offer net benefits to the borrower country when additional investment is generated (from the swap transaction itself and/or from encouraging further investment as a result of the swap policy); they offer net benefits to the lender when future loan servicing prospects are poor and viable investment opportunities exist; and they offer net benefits to the direct investor when the cost of financing the investment through the swap is less than for alternative financing sources.
The analytical framework presented here allows the bank lender to formally compare alternatives of holding impaired LDC loans on its books, selling the loans in the secondary market, trading the loans for loans from another country, and swapping the loans for equity investments in the borrowing country. It similarly allows the government policymaker to compare the relevant economic costs and benefits of swaps, so that better swap policies can be developed. 相似文献

Summary. Combining a strategy model, an inference procedure and a new experimental design, we map sequences of observed actions in repeated games to unobserved strategies that reflect decision-makers’ plans. We demonstrate the method by studying two institutional settings with distinct theoretical predictions. We find that almost all strategies inferred are best responses to one of the inferred strategies of other players, and in one of the settings almost all of the inferred strategies, which include triggers to punish non-cooperators, are consistent with equilibrium strategies. By developing a method to infer unobserved repeated-game strategies from actions, we take a step toward making game theory a more applied tool, bridging a gap between theory and observed behavior.Received: 23 December 2002, Revised: 19 April 2005, JEL Classification Numbers:

The evolution of society and economic pressure has provided the impetus for operating on a 24-hr basis in many industries. This has occurred with relatively little attention toward sleep deprivation and related problems facing shift workers and the organizations employing them. This paper first documents the move toward shift work and some sleep problems associated with it. We then describe sleep disorders that impact job performance. Next, we describe alternative schedules and give suggestions for shift work implementation. Finally, we offer some normative advice regarding the treatment of shift employees. 相似文献

The analysis uses March Current Population Survey data to estimate state-level cross-section/time-series models of the effects of the unemployment rate on alternative poverty rates. The measures include the official headcount rate, and alternatives based higher thresholds, revised equivalence scales and income defined as inclusive and exclusive of taxes and cash and in-kind transfers. The estimated effects turn critically on the measurement approaches, both for the total sample population and for four population sub-groups. For several alternative poverty rate measures, the unemployment rate has no significant impact on poverty. By contrast, real per-capita median earnings have strong and consistently negative effects on the poverty rates of all groups studied. The findings thus provide important lessons for researchers exploring the links between economic conditions and poverty, and for policy makers developing poverty reduction strategies. 相似文献
