Is Livestock Important for Risk Behaviour and Activity Choice of Rural Households? Evidence from Kenya 总被引:1,自引:0,他引:1
This paper presents an alternative view on causes of differentiationin rural Kenya, focusing on the role of livestock as liquidassets. We use cross-sectional household data in Central andWestern Kenya. We first examine the extent to which householdsare liquidity-constrained in relation with livestock holdings.It is suggested that many rural households are currently liquidity-constrainedand liquidity constraints are closely associated with cattleholdings. We also find that a differentiation process in whichthe households with high endowments and livestock can augmenttheir income by directing more inputs to high-return activities,while poor households who are more likely to be liquidity-constrainedcannot. Our results show that the difference in liquid assetsand associated credit constraints is one of the possible causesfor differentiation of households in rural Kenya. 相似文献

This paper examines the effects of characteristics of bank underwriters on issue costs in seasoned equity offerings in Japan following deregulation in 1999. I find that banks’ holding loans have a negative effect on price discounts and no effect on underwriting fees. However, banks’ equity holdings have no effect on discount rates and a positive effect on underwriting fees. Furthermore, issuers with unhealthy banks pay higher discount rates, are more likely to be weak in their ex-post operating performance, and are less willing to switch underwriters. I conclude that the characteristics of banks have different effects on issue costs. 相似文献

Drawing upon cross-country panel data for developing countries, the present study examines the role of agricultural growth in reducing inequality and poverty by modelling the dynamic linkage between agricultural and non-agricultural sectors. For this purpose, we have compared the roles of agricultural and non-agricultural growth and have found that agricultural growth is more important in reducing poverty, while the negative effect of agricultural growth on inequality is found in a few cases where specific definitions of inequality are adopted. Our analysis generally reinforces the case for revival of agriculture in the post-2015 discourse, contrary to much-emphasised roles of rural–urban migration and urbanisation as main drivers of growth and elimination of extreme poverty. 相似文献

This paper focuses on the poverty alleviating potential of the Employment Guarantee Scheme (EGS) in (the Indian state of) Maharashtra. A point of departure is the shift of emphasis from the static to the dynamic effects of the EGS targeting, measured in terms of individuals moving into and out of poverty, over the period 1979-84. An assessment is made of whether the EGS prevents the vulnerable from falling into poverty or enables the poor to move out of poverty, by distinguishing between the protective and promotional roles of the scheme. Simulations involving a wide range of poverty thresholds and different assumptions about the distribution of EGS earnings reveal that the poverty alleviating potential is limited in most cases. If, however, a larger EGS outlay is combined with more accurate targeting, the potential is substantially greater. Larger outlays are feasible if other rural public works are merged under the EGS. If this is combined with a reallocation in favour of backward areas, the targeting may improve substantially. 相似文献

This paper compares pooled and non-pooled models of UK capital investment using the Confederation of British Industrys (CBI) Industrial Trends Survey, focusing on the impact of uncertainty. The uncertainty measure is based on the cross sectional dispersion of optimism about the future business conditions in the industry in which the firm operates. The panel data estimation shows that uncertainty has quantitatively important negative effects on investment. However, if we look at the estimation results at the industry level, we find a great diversity in both estimated elasticities and t-statistics, providing valuable information not available from the pooled model. Finally, we compare the forecast performances of the above models; this analysis confirms that pooled estimators are generally better than non-pooled estimators in terms of out-of-sample forecast performance, but the difference between the two is not very large. 相似文献

This paper argues that the comparatively low levels of businessstart-ups in Japan need not be a matter of concern in so faras the pattern of growth relying on existing companies persists.But the declining trend of start-up rates may be worrisome forit may indicate waning entrepreneurship and weakening mechanismsof resource reallocation and economic growth. Policy measuresto promote business start-ups are not based on well-foundedstudies at an aggregate level, which are lacking in the absenceof comparable data, but rather are inspired by the successfulUS experience. The paper looks into two specific areas of policy- private equity markets and bankruptcy - where important progresshas been made, and points to further scope for improvement. 相似文献

This paper addresses the design of container liner shipping networks taking into consideration container management issues including empty container repositioning. We examine two typical service networks with different ship sizes: multi-port calling by conventional ship size and hub-and-spoke by mega-ship. The entire solution process is performed in two phases: the service network design and container distribution. A wide variety of numerical experiments are conducted for the Asia–Europe and Asia–North America trade lanes. In most scenarios the multi-port calling is superior in terms of total cost, while the hub-and-spoke is more advantageous in the European trade for a costly shipping company. 相似文献

This paper analyzes the possibility to save container fleet management costs in repositioning empty containers through the use of foldable containers. We model this entire empty container flow as an integer programming problem with different strategies in empty container flow itinerary. The model is used to carry out numerical experiments that optimize the empty container repositioning in the hinterland, where there are serious empty container repositioning problems caused by extremely imbalanced trades. The study finds that foldable containers can substantially save on repositioning costs compared to the use of standard containers. 相似文献

Drawing upon new World Bank poverty data, the analysis examines the feasibility of attaining the Millennium Development Goal of halving extreme poverty (MDG1) when the interrelationships between finance, institutions, trade liberalization, growth and poverty are taken into account. The authors' econometric results suggest a slowing down of poverty reduction in the more recent years since 2000. They also confirm: the role of better institutions in income growth, poverty reduction, trade openness and financial development; the role of financial development in economic growth; and the positive effect of capital liberalization on financial development. Simulations for different regions show that MDG1 is attainable in most regions if the historical growth rate is maintained over 2006–15. However, improvements in institutional quality are crucial for halving extreme poverty in sub-Saharan Africa. 相似文献

We derive the valuation formula of a European call option on the spread of two cointegrated commodity futures prices, based on the Gibson–Schwartz with cointegration (GSC) model. We also analyze the American commodity spread option including the early exercise premium representation and an analytical approximation valuation formulae with cointegration. In the numerical analysis, we compare the spread option values calculated by the GSC model and the Gibson–Schwartz (GS) model that ignores cointegration. Consistent with the intuition that the cointegration prevents the prices from diverging, the GSC model prices the commodity spread option lower than the GS model which have longer maturity of more than 6 years. In other words, the GS model may overprice the commodity spread options for those with longer maturity without taking account of cointegration. Thus, incorporating cointegration is important for valuation and hedging of long-term commodity spread options such as large scale oil refining plant developments. 相似文献
