Abstract. Economists devote considerable energies towards refining their econometric techniques to overcome difficulties connected with conducting empirical research. Despite advances in technique. it is not clear whether further refinement in this direction is worthwhile for policy purposes. It may be that no further amount of statistical adjustment of inadequate data will increase understanding, and that better data is simply necessary to add to our knowledge. But rarely is sufficient credit paid to new forms of data. In short, econometric technique is emphasized to the neglect of data innovation, as if new data were merely lying about waiting for an ingenious suggestion for use. This paper surveys advances of the last twenty five years in estimating labour supply for policy purposes with a view towards appreciating the relative contribution of both improvements in econometric technique as well as developments of new data.
After briefly detailing the key parameters which economists have sought to estimate, we describe the early 'first generation' research (circa 1970), which is plagued by problems of unobservable variables, measurement errors, truncation and selectivity bias, and non linear budget constraints. 'Second generation' research constitute attempts to resolve one or more of these difficulties, and the respective contribution of econometric technique and new data is acknowledged and assessed, including the contribution of data generated by large scale social experiments in which participants are randomly assigned to different guaranteed income plans and their labour supply behaviour measured.  相似文献

All three pillars of the British pensions system are crumbling. The basic state pension is unsustainable in its present form. Defined benefit occupational pension schemes are fast disappearing, and with them the retirement hopes of millions of workers. A further 3 million low-income earners are not saving enough for their retirement. And uncertainty about pensions choices is widespread. In each case the primary cause of the problem is governmental or regulatory failure. The paper makes eight general and four specific proposals for restoring the system.  相似文献

Kamstra et al. [Kamstra, M.J., Kramer, L.A., Levi, M.D., 2000. Losing sleep at the market: the daylight saving anomaly. The American Economic Review 90, 1005–1011] argue that the mean weekend return following the changes in daylight saving time is less than the mean weekend return throughout the rest of the year. Opposing studies, such as Pinegar [Pinegar, J.M., 2002. Losing sleep at the market: comment. The American Economic Review 92, 1251–1256), reason that the observed results depend upon methodology. We extend the ongoing discussions by providing further evidence for equity markets and bond markets in Germany and across Europe. We further demonstrate that the daylight saving effect does not serve as a potential rationale for the weekend effect.  相似文献

This article provides a guide to economic information on Australian resource projects. Three sources are described in some detail and their differences, strengths and weaknesses are discussed. As the data are under‐researched, some examples of how they can be used in economic analysis are mentioned.  相似文献

This paper provides new empirical evidence on the relationship between the structure of firms’ overseas FDI and the performance and organisation of their home‐country operations in both manufacturing and business services. It addresses two questions. First, does sorting into multinational status on the basis of productivity extend to the scale of overseas activity? Second, is there evidence that off‐shoring to low‐wage countries has asymmetric effects on high and low‐skill activities in the home economy? The paper considers heterogeneity in firms’ outward FDI strategies and in their behaviour at home, distinguishing between low‐skill and high‐skill‐intensive activities. I differentiate between firms that invest in relatively low‐wage economies and hence might be engaged in vertical FDI, and those that only invest in high‐wage economies. I find that firms that invest in low‐wage economies simultaneously invest in a large number of high‐wage economies, employing complex FDI strategies. I add to existing evidence by demonstrating that selection into multinational status on productivity extends beyond the decision of whether or not to engage in FDI, to the geographic scope of overseas operations. This is consistent with the highest productivity firms being best able to overcome large fixed costs of establishing multiple overseas facilities. I find evidence consistent with differential effects of vertical FDI on firms’ high and low‐skill manufacturing activity in the UK. Relocating low‐skill activity to relatively low‐wage economies could enable a firm to expand output, with potential positive effects on investment, employment and output in complementary (high‐skill) activities at home. For firms investing in relatively low‐wage economies, I find that labour in these countries may substitute for relatively low‐skilled labour in the UK. In high‐skill manufacturing industries I find that multinationals that invest in low‐wage economies are larger, more capital intensive and more intensive in their use of intermediate inputs than other UK‐owned firms.  相似文献

ABSTRACT

The literature suggests that North American business-people differ from their Latin American counterparts with respect to specific behavioral traits. Our particular interest is in problem solving and in effecting changes in behavior to achieve better problem-solving capability. The purpose of the present study is to assess whether there are differences in problem-solving styles between two culturally different groups of managers registered in MBA Programs: Anglo American and Latin American. Using Kolb's (1984 2006) Learning Style Inventory, it was found that Anglo American managers tended to be relatively action-oriented, “Convergers” (they emphasize decision-making and use deductive reasoning), while Latin American managers tended to be reflection-oriented, “Assimilators” (they emphasize planning and like to create models in their analyses) in their problem-solving styles. The positive and negative aspects of each style are discussed and suggestions for improved decision-making are offered.

RESUMEN. La literatura sugiere que los empresarios norteamericanos difieren de sus contrapartes latinoamericanos, en lo que atañe a ciertos trazos comportamentales específicos. Nuestro interés particular se orienta a la solución de problemas e implementación de cambios comportamentales, con el propósito de adquirir habilidades específicas para la solución de problemas. El propósito de este estudio es evaluar si existen diferencias entre los estilos empleados para solucionar problemas entre diferentes grupos culturales de gerentes matriculados en Programas MBA angloamericanos y latinoamericanos. Usando el sistema de estilos de Kolb (1984 2006) denominado Learning Style Inventory, descubrimos que los gerentes angloamericanos tienden a orientarse con bastante frecuencia en la acción, los llamados ‘Convergentes’ (que hacen hincapié en la toma de decisiones y el uso del razonamiento deductivo), mientras que los gerentes latinoamericanos tienden a volcarse a la reflexión, los llamados ‘Asimiladores’ (que hacen hincapié enplanear y les gusta crear modelos en sus análisis), como característica de sus estilos para solucionar problemas. Discutimos los aspectos positivo y negativo de cada estilo, y hacemos sugerencias para mejorar la toma de decisión.

RESUMO. A literatura sugere que os homens de negócios norte-americanos diferem de seus colegas latino-americanos em traços comportamentais específicos. Nosso interesse particular recai sobre a resolução de problemas e a introdução de mudanças de comportamento para obter uma melhor capacidade de resolução de problemas. O objetivo deste estudo é avaliar se existem diferenças nos estilos de resolução de problemas de dois grupos culturalmente diferentes de gerentes matriculados em cursos de MBA: anglo-americanos e latino-americanos. Utilizando o inventário LSI (learning style inventory) de Kolb (1984 2006), constatou-se que os gerentes anglo-americanos tendiam a ser relativamente orientados para a ação, “convergentes” (eles enfatizam a tomada de decisões e o raciocínio dedutivo), enquanto os gerentes latinoamericanos tendiam a ser orientados para a reflexão, “assimiladores” (eles enfatizam o planejamento e gostam de criar modelos em suas análises) em seus estilos de resolução de problemas. Os aspectos positivos e negativos de cada estilo são discutidos, e sugestões para melhorar a tomada de decisões são oferecidas.  相似文献

This paper reviews the literature on the real effects of financial reporting and disclosure on corporate innovation, highlighting both the possible channels of influence and the potential challenges that researchers face when attributing causal effects. We discuss the concept of innovation, emphasising the specific characteristics that make investments in innovation difficult to report. We then provide a review of the nascent work relating disclosure to innovation, which we organise around three channels: financing, compensation and learning. Finally, we discuss recent efforts aimed at increasing the quality of corporate disclosures, including disclosures of firms’ innovative activities. Throughout the paper, we highlight the trade-offs of disclosure (reduced information asymmetry and increased proprietary costs), which are particularly exacerbated in the context of corporate innovation.  相似文献

We evaluate an agricultural extension program aimed at increasing on‐farm biodiversity in Alberta. Using reports prepared for program participants by the extension agency, customized surveys were used to collect data on whether recommended practices were adopted. Data were also collected from producers who were willing but unable to participate in the program due to its unexpected cancellation. A count model compared the number of practices adopted by participants and nonparticipants to evaluate the program's efficacy, and a probit model using participants’ adoption data were used to understand factors affecting adoption. Simple, low‐cost, and easily trialed practices were adopted at high rates, though some higher cost practices associated with observable benefits were also adopted at moderate or high rates. Farm‐specific characteristics, such as size, tenure, or group membership were also significantly linked to the likelihood of adoption. Results suggest that the extension program was successful in encouraging adoption of environmentally beneficial practices with caveats; project completion and quality were not verified, and decreasing marginal returns to extension efforts may have been realized within the small participant pool. Nous évaluons un programme d'éducation permanente en agriculture visant l'augmentation de la biodiversité fermière en Alberta. Utilisant des rapports préparés par les agences d'éducation pour les participants de programmes, des sondages individualisés ont servi à la collecte de données concernant l'adoption de pratiques recommandées. Des données ont aussi été recueillies auprès de producteurs qui auraient voulu participer mais qui n'ont pas profité du programme suivant son annulation inattendue. Un modèle de comptage a servi à comparer le nombre de pratiques adoptées par les participants et non‐participants pour évaluer l'efficacité du programme, et un modèle probit basé sur les données d'adoption par les participants a servi à comprendre les facteurs ayant un impact sur l'adoption. Les pratiques simples, peu coûteuses et faciles à tester ont été hautement adoptées. Certaines pratiques à coûts plus élevés, associées à des avantages observables, ont aussi vu des taux moyens et élevés d'adoption. Les caractéristiques spécifiques aux exploitations agricoles comme la taille, la longévité et l'adhésion à un groupe se sont aussi trouvées liées de façon significative aux probabilités d'adoption. Les résultats suggèrent que le programme d'éducation permanente a réussi à encourager l'adoption de pratiques bénéfiques pour l'environnement avec quelques bémols: la réalisation des projets et leur qualité n'ont pas fait l'objet de vérification, et la diminution des rendements marginaux en fonction des efforts d'éducation pourrait avoir été réalisée dans le cadre d'un petit bassin de participants.  相似文献
