Obesity and overweight are linked to diseases that cost society a significant amount of resources. While behavior modification can reduce the problem, instigating such lifestyle changes is an uneasy task. One potential way to reduce the problem is through the use of financial incentives. In this survey, we review the available evidence, properly emphasizing studies that credibly yield meaningful estimates of the effect of financial incentives on weight loss. We find that the scientific literature on the subject has not yet satisfactorily settled whether such a mechanism is effective at eliciting the desired behavioral and health outcomes. We therefore advocate a rigorous large‐scale randomized experiment to provide reliable estimates of the effect. 相似文献
According to political business cycle theory, separate opportunistic and partisan approaches exist. It is obvious, as seen from theoretical and empirical points of view, that politicians aim for both opportunistic as well as partisan goals. This paper presents a model of a pre‐election political business cycle that manifests an indication of competence and a post‐election political business cycle that occurs because of the uncertainty of an election's winner monetary policy. In the pre‐election period competent governments expand the economy. The post‐election cycle depends on whether a leftist or a conservative government is in power in the pre‐election period, and if they are re‐elected or not. 相似文献
For buying companies, supplier resource mobilisation is an essential process in gaining and sustaining preferential access to supplier resources. This editorial provides insights into the processes of supplier resource mobilisation and introduces three empirical studies on supplier resource mobilisation. We first introduce the supplier resource mobilisation cycle. This cycle may serve as a roadmap for purchasing and supply management (PSM) practitioners seeking to improve access to supplier resources. In addition, this article informs PSM scholars about the status of the supplier resource mobilisation literature and proposes avenues for future research. The cycle includes six stages: (1) becoming an attractive customer, (2) segmenting suppliers, (3) generating supplier satisfaction, (4) becoming a preferred customer, (5) engaging in supplier-oriented actions, and (6) integrating supplier resources. Finally, we introduce the articles in this issue that each examine a different stage of the supplier resource mobilisation process. 相似文献
Once a popular colonial monetary arrangement, currency boards fell into disuse as countries gained political independence. But recently, currency boards have made a remarkable come-back. This essay takes a critical look at their performance. Are currency boards really a panacea for achieving low inflation and high growth? Or do they merely provide a 'quick fix' allowing authorities to neglect fundamental reforms and thus fail to yield lasting benefits? We have three major findings. First, the historical track record of currency boards is sterling, with few instances of speculative attacks and virtually no 'involuntary' exits. Countries that did exit from currency boards did so mainly for political, rather than economic reasons, and such exits were usually uneventful. Second, modern currency boards have often been instituted to gain credibility following a period of high or hyperinflation, and in this regard, have been remarkably successful. Countries with currency boards experienced lower inflation and higher (if more volatile) GDP growth compared to both floating regimes and simple pegs. The inflation difference reflects both a lower growth rate of money supply (a 'discipline effect'), and a faster growth of money demand (a 'credibility effect'). The GDP growth effect is significant, but may simply reflect a rebound from depressed levels. Third, case studies reveal the successful introduction of a currency board to be far from trivial, requiring lengthy legal and institutional changes, as well as a broad economic and social consensus for the implied commitment. Moreover, there are thorny issues, as yet untested, regarding possible exits from a currency board. Thus currency boards do not provide easy solutions. But if introduced in the right circumstances, with some built-in flexibility, they can be an important tool for gaining credibility and achieving macroeconomic stabilization. 相似文献
International Financial Reporting Standards (IFRS) are now required or permitted for use by companies in more than 100 countries, including the majority of the G20 members. However, domestic public companies domiciled in the United States (US) continue to be required to file financial statements with the Securities and Exchange Commission (SEC) in accordance with US Generally Accepted Accounting Principles (US GAAP), and are prohibited from preparing them based on IFRS. This article describes the developments of IFRS‐related activities and initiatives in the US over the period 2007–2012, and provides an overview of the current status regarding potentially incorporating IFRS into the US financial reporting system based on recently issued reports by the SEC.相似文献
Industrial markets are frequently characterized by an oligopolistic market structure. As a result, suppliers may become highly selective with respect to decisions that involve collaborating with certain customers. Buying firms must therefore be more attractive than their rivals to obtain opportunities to collaborate with these selective suppliers. This apparently counterintuitive inversion of the classical marketing approach (that is, relationships that involve buyers competing for suppliers rather than the other way round) constitutes the foundation of the special issue that is introduced in this paper. In this paper, we present key terms and propose a model of preferred customership that uses a social exchange perspective to link customer attractiveness, supplier satisfaction and preferred customer status. The papers that contribute to this special issue are introduced within the context of this framework. Finally, this paper concludes with suggestions for future research directions. 相似文献
The paper presents an empirical analysis of “outsourcing” using establishment‐level data for UK manufacturing industries. The authors analyze an establishment's decision to outsource and the subsequent effects of outsourcing on the establishment's productivity. Outsourcing is compared in domestic with foreign‐owned establishments. The empirical results suggest that high wages are positively related to outsourcing, suggesting that the cost‐saving motive is important. Foreign‐owned firms have higher levels of outsourcing than domestic establishments. In the productivity analysis, an establishment's outsourcing intensity is positively related to its labor productivity and total factor productivity growth, and this effect is more pronounced for foreign establishments. 相似文献
It is a well known fact that economic development and distance to the equator are positively correlated variables in the world today. It is perhaps less well known that as recently as 1500 C.E. it was the other way around. The present paper provides a theory of why the ‘latitude gradient’ changed sign in the course of the last half millennium. In particular, we develop a dynamic model of economic and physiological development in which households decide upon the number and nutrition of their offspring. In this setting we demonstrate that relatively high metabolic costs of fertility, which may have emerged due to positive selection towards greater cold tolerance in locations away from the equator, would work to stifle economic development during pre-industrial times, yet allow for an early onset of sustained growth. As a result, the theory suggests a reversal of fortune whereby economic activity gradually shifts away from the equator in the process of long-term economic development. Our empirical results give supporting evidence for our hypothesis.
This paper investigates whether knowledge accumulating activities, such as exporting, R&D, or worker training, can enhance plants' productivity. To this end, we use plant‐level panel data for Irish manufacturing. Our results importantly indicate that productivity enhancing effects of these factors are found only for domestic firms, but not for foreign multinationals located in Ireland. We postulate a number of potential reasons inherent to multinational activity possibly driving this result. 相似文献
