In the European Union, a series of competencies are shared between a central agency called the European Commission, and the governments of the Member States. This paper focuses on two of those policies: research and regional development. Here, we model and discuss how the level of commitment of a central authority toward poor regions affects the design of the best decision-making process. We explore cases of full centralization and full decentralization, and situations where the two levels of government are allowed to take decisions, either simultaneously or sequentially. In the latter case, we make a distinction between a situation where the central agency decides first as in most federations, and one in which it decides second, then being an agent of national governments. This setting is especially relevant for the European Union. We show, in particular, that when the degree of commitment of the center is high, assignment of redistributive competencies to both levels of power is a proxy for centralization. Additionally, the poorer region may find its best interest in an institutional design where the regions decide first. 相似文献

Abstract This article aims at investigating the interplay between environmental quality, health, and economic development in a unified OLG framework. Human capital accumulation depends on the environment through its impact on children’s health and workers’ productivity. In turn, environmental quality dynamics rely upon human capital that determines maintenance efforts. This two‐way relationship generates a co‐evolution of human capital and environmental quality in the long run. Along the transition path, the dynamic interactions between economic and environmental spheres allow for replicating two different trajectories: some economies experiment an Environmental Kuznets Curve while some others are caught into the environmental poverty trap. 相似文献

We consider an overlapping generations economy in which agents differ through their ability to procreate. Ex‐ante infertile households may incur health expenditure to increase their chances of parenthood. This health heterogeneity generates welfare inequalities that deserve to be ruled out. We explore three different criteria of social evaluation in the long‐run: the utilitarian approach, the ex‐ante egalitarian criterion and the ex‐post egalitarian one. We propose a set of economic instruments to decentralize each solution. To correct for the externalities and health inequalities, both a preventive (a taxation of capital) and a redistributive policy are required. We show that a more egalitarian allocation is associated with higher productive investment but reduced health expenditure and thus, lower population growth. 相似文献

This article derives a central bank's optimal liquidity supply towards a money market with an unrestricted lending facility. We show that when the effect of liquidity on market rates is not too small, and the monetary authority is concerned with both interest rates and liquidity conditions, then the optimal allotment policy may entail a ‘discontinuous’ reaction to initial conditions. In particular, the model predicts a threshold level of liquidity below which the central bank will not bail out the banking system. An estimation of the liquidity effect for the euro area suggests that the discontinuity might have contributed to the Eurosystem's tight response to occurrences of underbidding during the period June 2000 through March 2004. 相似文献

A major problem affecting world fisheries today is overcapacity of which overfishing is both a cause and a consequence. There is a general consensus that fisheries subsidies cause great harm to the resource by exacerbating the problems resulting from the common resource issues of fisheries leading to overexploitation of the resource through a new set of perverse incentives. Many now advocate that subsidies should gradually be terminated, and that capacity enhancing and fuel subsidies should be terminated immediately. On account of the global fisheries crises, highly subsidised fisheries and the anticipated reforms of the European Union's Common Fisheries Policy this study aimed to estimate the impact of eliminating fisheries subsidies on various macro and micro economic variables pertaining to the regional economy of the Azores using a dynamic computable general equilibrium model based on a social accounting matrix. The simulation results suggest that reduction, and in particular, elimination of fisheries subsidies would have a substantial effect on the region, however, the negative social and economic effects would be largely confined to the fishing sector. Conversely, the augmentation of fishery subsidies would benefit the fishing sector with an overall adverse effect on the rest of the economy. 相似文献

This article explores Latin American Chief Executive Officers' (CEOs') perceptions about the influence of career self-management practices and chance events on their career pathways. Through an edited topical life story approach, we investigate the relationship between those variables throughout CEO's career trajectories in the Latin American context. Semi-structured in-depth interviews with 22 CEOs working for multinational companies were conducted. Interviews were transcribed and analyzed with the aid of QSR NVivo 7 software. The study showed that even in volatile macroeconomic environments, typical of Latin American countries, CEOs do plan their careers. Career planning constitutes the backbone of the career management process. To deal with low predictability chance events, CEOs relied on active development network as the main career self-management practice. However, choice of mobility was the key career self-management behavior when responding to high predictability chance events. These central strategies were frequently combined with other career self-management practices, taking into consideration the type of chance event being responded to. According to this study, if individuals want to develop their careers in unstable environments, they will need to be proficient in career self-management practices, with particular emphasis on network development and choice of job mobility, as well as in happenstance skills. 相似文献

Social researchers increasingly survey children and young adolescents.They are convinced that information about perspectives, attitudes, and behaviors of childrenshould be collected from the children themselves. Methodological expertise on surveying childrenis still scarce, and researchers rely on ad-hoc knowledge from fields such as child psychiatry and educationaltesting, or on methodological knowledge on surveying adults. Regarding adults, empirical evidenceshows that respondent characteristics (cognitive abilities) as well asquestion characteristics (question difficulty) affect response quality.This study reports on a methodological survey experiment on theeffect of negatively formulated questions, the number of response options and offeringa neutral midpoint as response option question characteristics on the reliability of theresponses, using children and young adolescents as respondents.The study shows no effects of negatively formulated questions onthe reliability measures, although children respond consistently differently on negativelyformulated questions than on positively formulated questions. Taking all results on the effectsof number of response options and offering a neutral midpoints on the different reliabilitymeasures into consideration; it would appear that offering about four responseoptions is optimal with children as respondents. 相似文献

The idea that real estate could have contributed to banking crises during the Great Depression has been downplayed due to the conservatism of mortgage contracts at the time. For instance, loan‐to‐value ratios often did not exceed 50 per cent. Using newly discovered archival documents and data from 1934, this article uncovers a darker side of 1920s US mortgage lending: the so‐called ‘second mortgage system’. As borrowers often could not make a 50 per cent down payment, a majority of them took second mortgages at usurious rates. As theory predicts, debt dilution, even in the presence of seniority rules, can be highly detrimental to both junior and senior lenders. The probability of default on first mortgages was likely to increase, and commercial banks were more likely to foreclose. Through foreclosure they would still be able to retrieve 50 per cent of the property value, but often after a protracted foreclosure process. This would have put further strain on banks during liquidity crises. This article is thus a timely reminder that second mortgages, or ‘piggyback loans’ as they are called today, can be hazardous to lenders and borrowers alike. It provides further empirical evidence that debt dilution can be detrimental to credit. 相似文献

This article proposes a computer‐intensive methodology to build bonus‐malus scales in automobile insurance. The claim frequency model is taken from Pinquet, Guillén, and Bolancé (2001) . It accounts for overdispersion, heteroskedasticity, and dependence among repeated observations. Explanatory variables are taken into account in the determination of the relativities, yielding an integrated automobile ratemaking scheme. In that respect, it complements the study of Taylor (1997) . 相似文献

This paper presents an overlapping generations model where pollution, private and public health expenditures are all determinants of longevity. Public expenditures, financed through labour taxation, provide both public health and abatement. We study the role of these three components of longevity on welfare and economic stability. At the steady state, we show that an appropriate fiscal policy may enhance welfare. However, when pollution is heavily harmful for longevity, the economy might experience aggregate instability or endogenous cycles. Nonetheless, a fiscal policy, which raises the share of public spending devoted to health, may display stabilizing virtues and rule out cycles. This allows us to recommend the design of the public policy that may comply with the dynamic and welfare objectives. 相似文献
