近年来,全球渔业普遍面临着过度投资、种群枯竭、渔获量下降和资源利用冲突加剧等问题,严重阻碍了渔业可持续发展目标的实现。本论文从经济学的角度,分析了渔业经济绩效最大化问题、渔业过度投资和渔业资源过度利用问题、渔业管理制度安排及其激励效应问题。在此基础上,总结归纳了成功的渔业管理制度必须满足的一些必要条件。  相似文献

Framing effects on retail store choice decisions were investigated in four experiments. Subjects preferred the store that guaranteed (a sure option) good prices (experiment 1), product availability (experiment 2), or a rebate (experiment 3) when consequences were framed in terms of gains; subjects preferred the risky option when consequences were framed in terms of losses. Consistent with fuzzy-trace theory, framing effects were reduced when the expected values of options were disparate in a direction that disfavored sure gain or probabilistic loss options (experiment 2) and when the perceived costs of committing a judgmental error were high (experiment 3). Experiment 4 shows that the moderating effects of disparate expected values and costs of judgment errors generalize to within-subject designs.  相似文献

个人所得税功能分析及政策选择   总被引:1,自引:0,他引:1  
个人所得税是目前增长最快的税种之一 ,是政府用来干预、调节经济活动的重要经济杠杆和调节社会收入分配的重要工具 ,在发挥其作用的同时 ,却产生了对劳动力和私人储蓄的替代效应 ,从我国近几年的运行状况来看 ,个人所得税无论是从税制的最初设计还是征管方面存在着严重不足 ,在政策选择上宜采取综合所得征收制及双向申报制  相似文献

积极财政政策的可持续性分析   总被引:1,自引:0,他引:1  
本文分别从当前宏观经济形势、我国政府债务风险和公共部门投资的挤出效应三个方面考察了我国积极财政政策的可持续性。认为我国当前的经济形势下 ,积极财政政策的淡出还为时尚早 ;我国单纯的国债风险并不高 ,但是我国政府的综合债务风险却相当大 ,控制我国综合债务风险的关键是控制存量 ;我国公共部门对民间投资的挤出效应不明显 ,当前民间投资不活跃的主要原因是另一种“挤出效应” ,即对民间投资的歧视和限制 ,要改变这种情况的主要方法是改革  相似文献

French banks and non‐financial companies issue index‐linked debt whose value at maturity is indexed to the CAC 40 or to a basket of European indices. This paper examines stock announcement effects associated with these bonds on three dates: the date the issuer's General Assembly decides future capital needs, the publication in the journal of the COB (the stock market board), and the issue date. We find the issuance of index‐linked debt has significant positive announcement effects on the issue date, which we attribute to its market‐completion property. In order to examine further whether market completion is at play, we decompose the value of the bond at issue into its straight bond and option values. We determine that the bonds are overvalued again supporting market completion.  相似文献

After controlling for survivorship bias, we examine the relation between average returns, firm size, and price levels for Canadian stocks during the 1975-1994 period. Our findings indicate that there is a significant inverse share price level effect in Canadian markets. When we compare the results of the overall sample with the groups of surviving firms and delisted stocks, the latter group shows strong performance for large-size, high-priced stocks. Evidence that supports an independent size effect is less clear for Canadian stocks. A small size effect exists only among the higher share price denominations, which suggests a confounded size-price effect. Although the delisted group returns are statistically different from those of the survivor and the overall groups, which implies some evidence of survivorship bias, the difference between the survivor group and the overall group is weak at best.  相似文献

In Italy, public expenditure reduction is achieved through a revision of social security and health care programs. In particular, public health expenditure control has been implemented through a reform that imposes more stringent budget rules to local governments and a considerable reduction in grants-in-aid from the central government. This paper investigates empirically whether the response to this decrease in categorical lump-sum grants from the central to local governments results in an asymmetric response to intergovernmental grants. Hard budget and soft budget constraint hypotheses are estimated by using a sample of cross-sectional and time observations covering the 20 Italian regions over the period 1989–1993. The main finding is the existence of a standard and a super flypaper effect in both models. The introduction of the soft-budget constraint hypothesis results in a stronger effect of grants and a lower response of own resources which shows that local governments prefer to incur some deficit instead of reducing health care expenditure.  相似文献

We analyze the impact of monetary policy on inflation, interest rates and exchange rates in a model with segmented asset markets developed by Grossman and Weiss (1983) and Rotemberg (1984, 1985). We find parameters for which real and nominal exchange rates in this model are (1) much more volatile than interest rates, inflation rates, and money growth rates, (2) highly correlated with each other, and (3) highly persistent. While this model fails to match the data in other important respects, it illustrates a potentially useful approach to modelling exchange rate behavior.  相似文献
