Economic and Environmental Benefits of Eliminating Log Export Bans – The Case of Costa Rica

An increasing number of tropical timber‐producing nations have enacted bans on export of logs arguing that this will reduce deforestation, expand downstream wood processing and improve the scale efficiency of domestic processing, create jobs and retain more value‐added nationally. The theoretical literature is clear that trade restrictions are generally welfare reducing (except in special cases such as when there is a potential for an optimal export tax). At best, a log export ban is a second‐best policy tool for reducing deforestation and addressing the associated environmental externalities. In overall terms, the suggestion that log export bans can achieve the objectives expected of them is dubious. However, very little quantitative evidence exists to demonstrate this claim and the paper attempts to address this gap by looking at the economic and environmental impacts of eliminating a log export ban in Costa Rica. The authors argue that eliminating the export ban is Pareto improving and could generate economic gains as high as $14 million per annum with the possibility of relatively modest environmental benefits.     

Income taxes, spending composition and long-run growth

The focus of this paper is threefold. First, it reexamines the impact on long-run growth of changes in flat-rate income taxes when a fraction of total government expenditures is used to provide public services that affect the productivity of privately held inputs. Second, for a given tax policy, this paper studies the impact of government expenditure composition on the rate of economic growth. Third, since demographics follow an overlapping generations structure and fiscal policy affects the economy's productivity, the paper features the role of productivity as a means of redistributing income across generations. The economy is analyzed numerically and policy experiments are carried out.     

Optimal job design in the presence of implicit contracts

We characterize the optimal job design in a multitasking environment when the firms use implicit contracts (i.e., bonus payments). Two natural forms of job design are compared: (i) individual assignment, where each agent is assigned to a particular job and (ii) team assignment, where a group of agents share responsibility for a job and are jointly accountable for its outcome. Team assignment mitigates the multitasking problem but may weaken the implicit contracts. The optimal job design follows a cutoff rule where only the firms with high reputation concerns opt for team assignment. However, the cutoff rule need not hold if the firm can combine implicit incentives with explicit pay‐per‐performance contracts.     

Vocational skills in the accounting professional profile: the Chartered Institute of Management Accountants (CIMA) employers' opinion

The increasingly dynamic environment in which accountants work has necessitated a reorientation of accounting education. In some countries this issue has raised great interest amongst accounting educators and practitioners. The ongoing debate has already resulted in the publication of several statements and research papers that have raised the question of the relevance of the role of vocational skills in accounting education. Examples of these vocational skills are communication skills, interpersonal skills, and problem-solving skills. This paper reports on the importance that the employers of management accountants gave to a specified set of vocational skills and capabilities and the level of ability of these skills exhibited by students. In order to prioritize future developments an integrated analysis of the two attributes, importance and exhibited level, is enabled by the use of strategic mapping. The results of this study suggest that the employers perceive deficiencies in several capabilities that they have identified as being quite important. These deficiencies exist, in the employers' opinion, both prior to recruitment and on professional qualification. The research also indicates that, in the opinion of these employers, the development of these skills should be a central concern for universities and professional bodies. The employers also indicated that vocational skills should be attained in an integrated way.     

Stock Market Mean Reversion and the Optimal Equity Allocation of a Long-Lived Investor

This paper solves numerically the intertemporalconsumption and portfolio choiceproblem of an infinitely-lived investor whofaces a time-varying equity premium.The solutions we obtain are very similarto the approximate analytical solutionsof Campbell and Viceira (1999), except atthe upper extreme of the state spacewhere both the numerical consumption andportfolio rules flatten out.We also consider a constrained version ofthe problem in which the investor facesborrowing and short-sales restrictions.These constraints bind when the equitypremium moves away from its mean in eitherdirection, and are particularly severe forrisk-tolerant investors. The constraints havesubstantial effects on optimalconsumption, but much more modest effects onoptimal portfolio choice in theregion of the state space where they are notbinding.     

Aqui No Se Habla Agencia.* An Examination of the Impact of Adverse Selection and Framing in Decision‐Making: a US/Mexico Comparison

US companies seeking cheaper labor or extraordinary returns have often seen foreign direct investment as a panacea. However, many of these companies founder on the horns of a control dilemma. While raw economic data such as labor rates prove to be true, productivity and decision‐making styles are so different that companies fail to maximize their investment returns. This situation is worsened as companies attempt to impose culturally inappropriate home country controls on their foreign investment. This study examines one of the potential sources of failure, escalation of commitment, which occurs when decision‐makers over‐commit incremental resources to failing investments without reasonable probability of recovery. This behavior has been widely documented in US domestic literature (see Whyte and Hook, 1997 , for a summary). However, there is also some evidence that such behavior is culturally bounded ( Chow et al., 1997; Sharp and Salter, 1997; Greer and Stephens, 2001 ). This study extends previous findings on cross‐cultural differences in decision‐making among managers by comparing the responses of managers in the USA and Mexico to an escalation of commitment exercise. The cross‐cultural validity of two US based theories, agency (adverse selection) and framing (prospect theory), is tested. The results indicate that at base Mexican managers were more risk seeking. However managers from the more individualistic USA were significantly more likely than Mexican managers to escalate in the presence of agency (adverse selection) based incentives. Negative framing among managers was universal in escalating commitment.     

Risk compensation in wages – a replication

We use data from Germany, The Netherlands, Portugal and Spain to test for the effect of earnings variation on individual earnings. We replicate estimates for the USA and find that the variance of earnings in an occupation affects individual wages positively while the skewness of earnings has a negative effect. Both results are in conformity with wage compensation for risk averse workers. First version received: March 2001/Final version received: July 2002 We are grateful to two anonymous referees for valuable comments.     

The role of human resources strategy in export performance: A longitudinal study

This longitudinal study examines the effect of human resources strategy on the export performance of 388 Florida firms. After controlling for differential firm advantages, managerial perceptions and aspirations, and marketing activities, results show that the way human resources are selected, deployed, compensated and motivated will play a significant role in subsequent export performance.     

Separating uncertainty from heterogeneity in life cycle earnings

This paper develops and applies a method for decomposing crosssection variability of earnings into components that are forecastableat the time students decide to go to college (heterogeneity)and components that are unforecastable. About 60% of variabilityin returns to schooling is forecastable. This has importantimplications for using measured variability to price risk andpredict college attendance.
