THE ESTIMATED EFFECT OF CATHOLIC SCHOOLING ON EDUCATIONAL OUTCOMES USING PROPENSITY SCORE MATCHING

This paper examines the effect of attending a Catholic high school on educational outcomes. The statistical analysis is based on data obtained from the US National Educational Longitudinal Study. Using propensity score matching methods to control for selection bias, we find that Catholic schooling improves maths test scores, with stronger effects for males than for females, but appears to have little effect (if any) on reading scores. Catholic schooling also raises high school graduation rates and substantially increases the likelihood of enrolment in a 4‐year college. Use of the difference‐in‐difference method suggests that the effect of Catholic schooling on changes in maths scores is more muted, though still statistically significant.     

Why Markets in Proto-Deceptive Goods Should Be Restricted

In recent years there has been much philosophical discussion over the question of whether the prohibitions on markets in such items as human body parts and gene sequences, and services such as human reproductive labor and sex, should be lifted. Yet despite the attention paid to this issue there are been surprisingly little discussion of the question of whether markets in certain items that are currently freely traded should be restricted or eliminated. In particular, there has been little discussion of the question of whether markets in items that could be readily used to deceive people should be restricted. I argue in this paper that one of the central moral values of the contemporary West – respect for personal autonomy – requires that such markets be restricted.     

Unraveling the Academic Productivity of Economists: The Opportunity Costs of Teaching and Service

This study investigates the relationships among research productivity, teaching, and service on the basis of individual-specific information involving approximately 715 academic economists. Responding to an online survey, these economists provided information regarding their teaching and service commitments as well as personal and institutional information. The publication record of each respondent was then obtained from EconLit. Together, these data constitute a rich field for the systematic study of research productivity. Results of a Tobit analysis reveal much about the nature of research productivity, underscoring, for instance, the importance of gender, coauthorship, presentations at conferences, and peers who publish. Among the more important findings from this analysis is that both teaching and service commitments have a significantly negative impact on the research productivity of academic economists. These relations hold across types of academic employer, though to varying degrees. Taken together, the results provide interesting insights into the roles of academic scholars, teachers, and colleagues.     

Accounting for Executive Stock Options: A Case Study in Avoiding Tough Decisions

We review the development of accounting requirements for executive stock options (ESOs) and find that the standard-setting process has been susceptible to pressure groups including the corporate sector, politicians and even the accounting profession itself. The failure of Australian and overseas accounting regulators to take tough decisions may have created a systematic bias towards the use of ESOs which can result in grossly inefficient compensation structures motivated by a desire to maximise reported profits rather than to create optimal managerial incentives. We conclude that most of the arguments against recognition of stock option expense can be dismissed as blatant self-interest at worst, or remarkably muddled thinking at best.     

Retirement and transition phenomena in the family purchase process

Research is needed on the family purchase process of retirement‐age couples, because 78 million baby boomers are rapidly approaching retirement age. Both boomers and the retirement‐age couples in this study present special opportunities to marketers through new roles adopted in retirement. This study reports on perceptions of family purchase process participation among retirement‐age couples. Results indicate that transition retirees' family purchase process participation differs from that of post‐transition retirees. This finding has managerial implications for marketers wishing to serve desirable segments of current and future retirement‐age consumers. © 2007 Wiley Periodicals, Inc.     

Optimal Flex Cropping and Storage of Spring Wheat under a Progressive Income Tax

This article presents two versions of a stochastic dynamic programming model: one version is used to obtain the optimal decision rule for flex cropping of spring wheat assuming sale of grain at harvest, while the second version is used to obtain the jointly optimal decision rule for flex cropping and storage of spring wheat. The objective function for the model is the expected present value of after-tax income. The first version of the model illustrates that the flex cropping strategy that maximizes the present value of after-tax income differs from the strategy that maximizes the present value of before-tax income. The second model illustrates that production and grain-storage marketing decision rules are inseparable under a progressive income tax. That is, the optimal flex cropping strategy assuming sale of grain at harvest differs substantially from the flex cropping strategy when grain storage is permitted. L'article propose deux versions d'un modèle de programmation dynamique stochastique: I'une est utilisée pour obtenir la décision optimale d'emblaver ou non en blé de printemps en prévision de la vente du grain à la moisson, I'autre recherchant une décision optimale d'assolement du blé avec intention de stocker à la récolte. La fonction objective du modèle est la valeur actuelle attendue du revenu après taxe. La première version révéle que la stratégic d'assolement axée sur une valeur actuelle maximale après imposition, diffère de celle qui est axée sur la valeur actuelle du revenu avant impostion. Le second modèle montre que les décisions de production et de vente ou de stockage du grain sont inséparables dans un régime d'imposition progressive. C'est-à-dire que la stratégie optimale axée sur la vente à la moisson est sensiblement différente de celle qui suppose le stockage du grain à la récolte.     

On the efficiency of the Cochrane-Orcutt estimator

Using analytic approximations, we reconcile some radically contradictory evidence and resolve an interesting paradox that occurs in a simple linear model with autocorrelated disturbances. In general, the behavior of conventional coefficient estimators is quite sensitive to the specification of the exogenous variables, or, equivalently, to whether the marginal efficiency or the conditional efficiency of the coefficient estimators is being compared.
