This study explores the effects of Vietnam's transition on the welfare of different ethnic groups in rural Vietnam. It draws on three rounds of national household surveys in 2002, 2004 and 2006. It is first observed that the pace of poverty reduction for minorities surpassed the majority over the period 2002–2006, although poor people were still concentrated in the minority groups throughout the period. Secondly, the disparity in living standards has been widening. In particular, inequality within both the majority and minority groups increased over the period. Thirdly, the study shows that the effect of economic growth on poverty is estimated to have been greater if inequality remained constant. It is also noted that the impacts of economic growth on poverty vary across different ethnic groups. Finally, regression decompositions of within inequality have confirmed that the main driver of inequality is not the same among ethnic groups. Given the diversity across different ethnic groups, we can conclude that government policy aimed at equal access to infrastructure and more equal distribution of assets, such as land, for ethnic minority groups would lead to more equal distribution of consumption and poverty reduction of those groups. Also, consideration of local needs would be necessary in designing and implementing public policies, given the heterogeneous socio-economic circumstances surrounding each ethnic minority group. 相似文献

In this paper, we present indirect evidence that the IMFs insistence on foreign control of two large nationwide Korean banks in exchange for short-term support during the 1997 financial crisis helped restrain soft related lending practices. News signaling the likely sale of a bank to a foreign financial institution yields an average daily decrease of about 2% in the stock price of related borrowers. News indicating difficulty in finding an interested foreign investor generates an increase in the stock price of related borrowers of about the same magnitude. These signals have larger impacts on less-profitable, less-liquid, and more bank-dependent firms. 相似文献

Consistent with real option theory, the authors argue that the value of the Employment Guarantee Scheme (EGS) in rural India and its impact on workers' behavior does not depend so much on its income supplementation as on enlargement of opportunities in the uncertain local labor market. The choice between the EGS and other activities is modeled in a dynamic optimization framework, taking into account a fixed wage rate and certainty of employment under the EGS and a stochastic wage rate under other activities. Specifically, volatility of wages in the rural labor markets has important implications for switches into the EGS and for concomitant welfare effects. Under such conditions, the higher the EGS wage, the greater is its attractiveness to relatively skilled and affluent workers, and for those already in it to continue. These and related predictions of the model are validated by panel data estimation. 相似文献

This paper critically and selectively surveys the literature on protection for sale and discusses directions for future research in this area. It suggests that the standard approach needs to be augmented to provide more compelling tests of this model. 相似文献

This study addresses the storage arrangement of transshipment containers on a container yard, in order to carry out efficiently the ship handling operations at a terminal where mega-containerships call. An optimization model is specified to investigate the flow of containers from the mega-containership to feeder ships using intermediate storage at the yard. A heuristic based on the lagrangian relaxation is formulated. The quality of the heuristic approach is tested in a number of experiments. In the experiments, various situations are analyzed with respect to mega-containership arrival rates, some strategies for stack arrangements and terminal layouts. 相似文献

This paper assesses banking market integration in Japan during the period 1889-1938 using annual data on loan rates and spreads between loan and deposit rates. Banks in prefectures further from the financial centers exhibited higher loan rates and greater spreads than banks closer to the center, however, distance effects diminished over time, suggesting that banking markets became increasingly integrated due to declines in transaction costs. Additionally, loan rates and spreads varied negatively with the intensity of local bank competition, consistent with the notion of market segmentation. We speculate that Japan’s anti-competitive banking regulation might have slowed the process of banking market integration. 相似文献

The Hoggard–Whalley–Wilmott equation is introduced to model portfolios of European type options incorporating transaction
costs. The model gives rise to a nonlinear parabolic partial differential equation (PDE), whose nonlinearity reflects the
presence of transaction costs. We show analytically the existence of solutions which are not necessarily convex nor concave.
Numerical treatments are also given, which are devised to effectively handle an infinite domain and unbounded solutions.

This paper focuses on the vulnerability of rural households to poverty when a negative crop shock occurs. The analysis is based on the ICRISAT panel survey of households in a semi‐arid region in south India during 1975–84. Using a dynamic panel data model that takes into account effects of crop shocks, an assessment of vulnerability of different groups of households is carried out. What is somewhat surprising is that even sections of relatively affluent households are highly vulnerable to long spells of poverty when severe crop shocks occur. As such crop shocks are frequent in a harsh production environment, there must be a shift of emphasis in anti‐poverty measures from meeting income shortfalls among the poor to enabling the vulnerable to protect themselves better against these shocks. 相似文献

Poverty Dynamics of Households in Rural China 总被引:1,自引:0,他引:1
The objective of our study is to identify patterns and causes of households' transitions into and out of poverty using the long household panel data on rural China in 1989–2009. We propose a discrete‐time multi‐spell duration model that not only corrects for unobserved heterogeneity, but also addresses the endogeneity due to dynamic selection associated with household's livelihood strategies. The household choosing farming or out‐migration as a main livelihood strategy was more likely to escape from persistent poverty than those taking local non‐agricultural employment. The present study emphasizes the central role of agriculture in helping the chronically poor escape from poverty. 相似文献
