Price-raising drug enforcement suppresses drug use, but it is expensive and may increase property crime. This has led to contradictory
recommendations concerning how drug enforcement should or should not be used. We reconcile these recommendations by incorporating
the enforcement's effects on both drug use and on property crime within an optimal-control model that recognizes whether convicted
drug-involved property offenders are merely incarcerated or whether they receive some form of drug treatment. 相似文献

The aim of this work is to demonstrate how public university hospital (UH) managers can improve the process of decision-making by using the measurement of economic value added to the society (EVAS) generated by these organizations. Thus, the economic values of the organization and its departments were calculated, according to the theory studied: measurement model of economic result of Slomski (1996). It was considered the conduction of a case study in a public UH, evaluating its economic performance in a 3-year period. For the interpretation of results, the Data Envelopment Analysis (DEA) which categorized the departments of the hospital studied as efficient or inefficient was used. This study revealed that managers can improve the decision-making process by using the EVAS, since it has been established that this measurement of economic value has sensitivity to identify which of the economic value drivers should be emphasized in the management. 相似文献

The paper’s objectives are twofold: to propose an experimental simulation to measure scope economies between pairs of submarkets
and to point out the role of submarkets in explaining the concentration level in the pharmaceutical market. We simulate scope
economies consistent with the diversification choices of large international companies in the years 1987 and 1997. Our results
suggest that: i) the random diversification (that is no scope economies hypothesis) is rejected, and ii) scope economies are
significant. (JEL: C15, D21, L11, L65) 相似文献

This paper investigates the types of policy instruments responsible for the success of policy implementation through projects. Based on evidence from 12 comparative multiple case-studies, the paper provides an analytical insight from real practice on how and why different types of instruments lead to either successful or unsuccessful projects. In particular, the key finding is that in order for projects to implement policy successfully, policy instruments have to be designed based on specific systems thinking constructs related to flexibility. The findings provide the crucial but missing holistic conceptual direction for the development of implementation theory, which needs to overcome conceptual fragmentation and polarization. The findings also provide the insight as to how instruments really function which is essential to policy makers and project managers involved in public innovation programs. 相似文献

In this paper we estimate the DEA technical efficiency for 4796 Brazilian municipalities, by applying a recently proposed
“Jackstrap” method, which combines Bootstrap and Jackknife resampling techniques, to reduce the effect of outliers and possible
errors in the data set. We perform calculations to identify and eliminate high leverage municipalities, using different variants
of Data Envelopment Analysis (DEA), as well as Free Disposal Hull (FDH). Corroborating previous results, efficiency results
for the Brazilian municipalities show a clear relationship between the size of the municipality and its efficiency scores.
Indeed, under both DEA variants, smaller cities tend to be less efficient than larger ones hence indicating that the quality
of the frontier adjustment improves significantly as the size of the municipality increases. We present arguments that may
explain to some extent these findings, such as economies of scale and the excess spending due to revenue from royalties. However,
such effects require further, more careful examination. 相似文献

In the first empirical study on the topic, the authors examined the ability of investment professionals to distinguish between truthful and deceptive statements. A random sample of 154 investment professionals made judgments about a series of truthful and deceptive statements, some of which involved financial fraud. Investment professionals' lie detection accuracy was poor; participants performed no better than would be expected by chance. Accuracy in identifying lies about financial fraud was especially poor. Further, participants displayed poor metacognitive realism when assessing their own performance. The theoretical and practical implications for lie detection in the financial industry are discussed. 相似文献

The analysis of the determinants of differences in wages across workers has traditionally relied on the estimation of average earnings functions. In this article, we propose a new theoretical model where it is the workers who decide the amount they wish to invest in human capital, taking into account the costs of acquiring those skills, for the purpose of maximizing earnings. In this model, both human capital and marginal productivity are likely to be influenced by the individual’s (unobserved) characteristics such as ability or motivation, potentially giving rise to endogeneity problems. In this context, the empirical implementation of our theoretical model allows us, under certain assumptions, to obtain consistent estimates even under the assumption of endogeneity. We present an empirical application to the education sector using data from the Spanish Structure of Earnings Survey 2010. Our results show that females and workers in the private education sector face more difficulties in achieving their maximum potential wage. 相似文献
