This paper introduces a local version of envy-freeness and investigates its implications in a continuum agent economy with connected preferences. We show that the set of locally envy-free and Pareto efficient allocations coincides with the set of equal-income Walrasian allocations. 相似文献

We identify turning points in the value of the yen during the 1920s to determine which factors were perceived by market participants as affecting Japan’s probability of returning to the gold standard. The 1920s were marked by military expansionism, political turmoil, and other dramatic political and institutional events. We conclude that changes of power between the Kenseikai and Seiyukai parties and worsening diplomatic relations with China were primarily responsible for turning points in the value of the yen. The democracy movement and the associated expansion of suffrage seem not to have been viewed as important by contemporaries. 相似文献

This paper considers the problem of fair allocation among individuals with unequal production skills. We introduce the concept of productivity‐adjusted average no‐envy. It is shown that equal‐income Walrasian allocations are the only surviving allocations that are productivity‐adjusted average envy‐free and efficient when the original economy is infinitely replicated. We also examine local versions of productivity‐adjusted average no‐envy and other equity concepts. 相似文献

Poverty,undernutrition and vulnerability in rural India: role of rural public works and food for work programmes 总被引:1,自引:0,他引:1
Katsushi S. Imai 《International Review of Applied Economics》2011,25(6):669-691
This paper analyses the effects of access to Rural Public Works (RPW) or Food for Work programme (FFW) on consumption poverty, vulnerability and undernutrition in India using the large household data sets constructed by the National Sample Survey for 1993 and 2004. The treatment-effects model is used to take account of sample selection bias in evaluating the effects of RPW in 1993 or FFW in 2004 on poverty. We have found significant and negative effects of participation in RPW and the Food for Work Programme on poverty, undernutrition (e.g. protein) and vulnerability in 1993 and 2004. 相似文献

Abstract Dynamic fund protection provides an investor with a floor level of protection during the investment period. This feature generalizes the concept of a put option, which provides only a floor value at a particular time. The dynamic protection feature ensures that the fund value is upgraded if it ever falls below a certain threshold level. Gerber and Pafumi (2000) have recently derived a closed-form expression for the price of this protection when the basic portfolio follows geometric Brownian motion. In this paper we examine the pricing of this feature under the constant elasticity of variance process. Two approaches are used to obtain numerical results. First, we show how to extend the basic Monte Carlo approach to handle the particular features of dynamic protection. When a discrete-time simulation approach is used to value a derivative that is subject to continuous monitoring, there is a bias. We show how to remove this bias. Second, a partial differential equation approach is used to price dynamic protection. We demonstrate that the price of the dynamic protection is sensitive to the investment assumptions. We also discuss a discrete time modification of the dynamic protection feature that is suitable for practical implementation. The paper deals just with pricing and does not consider the important question of reserving for these contracts. 相似文献

Using maximum likelihood techniques and monthly panel data we solve and estimate an explicitly dynamic model of criminal behavior where current criminal activity impacts future labor market outcomes. We show that the threat of future adverse effects in the labor market when arrested acts as a strong deterrent to crime. Moreover, such forward‐looking behavior is estimated to be important. Hence, policies that weaken this deterrence will be much less effective in fighting crime. This suggests that prevention is more powerful than redemption since anticipated redemption allows criminals to look forward to negating the consequences of their crimes. 相似文献

Vulnerability and poverty dynamics in Vietnam 总被引:1,自引:0,他引:1
Drawing upon the Vietnam Household Living Standards Survey (VHLSS) data that cover the whole of Vietnam in 2002 and 2004, ex ante measures of vulnerability are constructed. These are then compared with static indicators of poverty (i.e. the headcount ratio in a particular year). Detailed analyses of the panel data show that (i) in general, vulnerability in 2002 translates into poverty in 2004; (ii) vulnerability of the poor tends to perpetuate their poverty and (iii) sections of the nonpoor but vulnerable slip into poverty. Durable reduction in poverty is conditional on (i) accurate identification of the vulnerable, (ii) their sources of vulnerability and (iii) design of social safety nets that would enable the vulnerable to reduce risks and cope better with rapid integration of markets with the larger global economy. 相似文献

Beginning in 2000, Japan’s postal saving system experienced a rapid outflow of funds as a large number of 10-year Postal Saving Certificates were maturing. This paper exploits this episode as a natural experiment in order to investigate the effects of a government-owned depository institution on local economic performance. The results show that the prefectures in which local funds were more heavily invested in the postal saving system in the early 1990s tended to experience a larger shift of funds away from the postal saving system and that these prefectures performed better in terms of output and small business creation in the early 2000s. 相似文献
