This paper investigates the welfare impact of a borrowing constraint that does not allow children to borrow against future income. In an overlapping-generations model with altruistic parents, the inability to borrow increases children’s savings and parental transfers, raising children’s welfare as well as average welfare in the short-run and in the long-run.Additionally, the borrowing constraint raises aggregate savings and, hence, physical capital. Consequently, when prices are flexible, the positive welfare impact of the constraint is higher.  相似文献

This study uses a manufacturing firm-level panel data set of South Korea for 2006–2013 to investigate the effect of financial constraints on the export performance of firms, with particular emphasis on the corporate ownership structure. The empirical results show that foreign multinational corporation (MNC) subsidiaries are not affected by financial constraint during both crisis and noncrisis periods, implying advantages of foreign ownership. However, domestic firms suffer more from financial constraints on exports during crisis years. In particular, domestic firms without parent firms are financially constrained during both crisis and noncrisis periods. However, those with parent firms do not experience financial constraints during noncrisis periods, although they too suffer from them during crisis periods. Thus, parent–subsidiary linkage among domestic firms plays an important role in alleviating financial constraints on export activity in noncrisis years but not as much during crisis years. Therefore, domestic parent firms exhibit less resilience to the global financial crisis, in comparison to foreign MNC parent firms.  相似文献

Using a Korean manufacturing firm-level data set covering a range of years from 2006 to 2013, this study investigates how the financial condition of firms, such as liquidity, leverage, and cash flow ratio, affects exit from export markets. It also analyses whether the financial status of foreign multinational corporation (MNC) subsidiaries differs from that of domestic firms with respect to the hazard of export market exit, especially during a global financial crisis. The empirical results confirm that, for domestic firms, the hazard of export market exit is affected by the firms’ financial condition only during a financial crisis. In other words, the financial vulnerability of domestic firms increases during the crisis, resulting in the hazard of export market exit. However, financial situations for foreign MNC subsidiaries do not affect exits from export markets, indicating a ‘finance-factor comparative advantage’.  相似文献

本文运用随机前沿计量分析方法,对我国上市公司的融资约束及其影响因素进行了实证研究。结果表明,融资约束在所研究的各行业是普遍存在的,且程度较为严重。在影响上市公司融资约束的因素中,国有控股公司相对非国有控股公司受到的融资约束程度要大,而股权的集中度与融资约束程度呈现出反向相关关系。同时结果显示,资本充足率越高、盈利能力越差的上市公司,受到的融资约束程度越大,而东部地区的上市公司受到的融资约束程度要小于中西部地区的上市公司。  相似文献

Food-for-work (FFW) is the most widely used type of public works program in Ethiopia through which a high share of the food aid is distributed. This paper assesses the impacts of FFW in Tigray, a chronically food insecure region in Ethiopia, in terms of relieving liquidity constraints and thereby improving input use in agriculture. A Heckman selection model on the adoption and intensity of fertilizer use demonstrated that FFW positively influenced the decision to adopt fertilizer and there was no evidence of disincentive effect.  相似文献

本文采用SML指数法测算了1998~2011年期间全国各地区的生产率指数和环境技术效率,进而在空间经济学框架下提出了经济关联、知识关联、规模收益和交通运输条件等可能引起效率集聚的因素,并运用“系统广义矩估计法”对这些因素的作用方向与方式作了实证检验。主要结论有:我国经济增长效率的空间分布具有明显集聚性;有限的技术效率是我国省域经济增长效率提升中的“短板”;中、西部地区具有以规模扩张为主要方向的粗放增长方式;经济关联、交通运输条件及产业结构等因素成为提升技术效率的“切入点”;FDI和资本密集型禀赋结构在经济增长效率提升中的作用具有“两面性”;我国省域经济增长效率表现出一定的趋同和溢出现象。  相似文献

We examine the relationship between fiscal deficits and per-capita income growth in a panel of 27 European countries, allowing for perceived risks, in terms of fiscal sustainability, associated with additional government spending. Such risks are proxied by the conditional variability of manufacturing production and stock market returns and by the unconditional variability of two survey-based economic-sentiment indicators. To help clarifying how fiscal variables impact on growth and to provide a point of reference for the interpretation of the empirical results a structural growth model is first identified. We find evidence of an asymmetric relationship, in that fiscal deficits give rise to adverse growth effects if they coincide with high uncertainty regarding the prospects of the economy and no significant negative growth effects in the low-uncertainty case.  相似文献

We consider superhedging of contingent claims under ratio constraint. It has been widely recognized that the minimum cost of superhedging a contingent claim with certain portfolio constraints is equal to the price of a claim with appropriately modified payoff but without constraints. In terms of the backward stochastic differential equation (BSDE) and the variational inequality equation approach, we revisit this result and provide two counterexamples.  相似文献

研究了带时间限制的最小费用运输问题,在分析了运量与运输时间关系的基础上,把运输时间划分成与运量无关和与运量有关的两部分;进一步根据已知的运输时间与运量的函数关系,把带时间限制的最小费用运输问题转化为最小费用最大流问题,给出了求解该问题的方法,并通过实例进行了计算。  相似文献
