Empirical analysis of household expenditure behaviour has traditionally ignored the issue of resource allocation between household members, assuming that they have identical or unitary preferences. This paper relaxes that assumption, develops a household sharing rule and proposes intra-household demand systems that are able to identify differences in the preferences of members from conventional data. The resulting price and expenditure elasticities are used to demonstrate that collective demand models suggest different directions for commodity tax reforms to those implied by the traditional unitary model.  相似文献

This study pools data on child anthropometrics and on their determinants from Pakistan, Peru, Jamaica, Russia and South Africa. It, then, estimates regression equations of child height and weight, measured by the Z-scores, on both combined country data and, separately, for each country. Moreover, the study estimates the child height and weight equations, separately, for young (0–36 months) and older children (37–72 months) and provides evidence on the impact of household assets and of a household’s access to basic amenities on the health of its children. The child health in the five countries chosen, which are culturally, economically, politically and geographically, quite diverse, are compared. The paper finds that the hard core cases of child malnutrition are not necessarily related to poverty or inequality. Female education plays an effective role in improving child health, with its beneficial effects considerably enhanced in households with access to public information through the radio or the TV.

We examine whether favorable information conveyed by stock split announcements transfers to nonsplitting firms within the same industry. On average, nonsplitting firms' shareholders experience positive and significant abnormal returns at the stock split announcements of their industry counterparts. In addition, industrywide and firm-specific characteristics are important determinants in explaining nonsplitting firms' stock returns. These firms' earnings increase significantly, and the earnings changes are positively related to the stock price reactions. Finally, we find no evidence that investors revise the value of nonsplitting firms because they anticipate a decline in earnings volatility.  相似文献

The Hannah-Kay [1977] generalized concentration index contains the well-known Herfindahl [1950]-Hirschman [1945] and the entropy indices as particular cases. In this papaer we show that the Hannah-Kay class can be regarded as a particular member of a generalized family of indices, which we refer to as self-weighted quasilinear means. We then show that among all self-weighted quasilinear means the Hannah-Kay family is the only class of concentration indices which satisfies the replication principle, a requirement which states that an m-fold replication of the industry, firm by firm, will multiply the concentration index by the factor 1/m.The refereeing process of this paper was handled through N.R. Adam.We are grateful to two anonymous referees for their suggestions.  相似文献

This note analyses the effect of the policy of tightening Intellectual Property Rights (IPR) on the rate of innovation in the North and on the welfare in both North and South in a model which is otherwise identical to Helpman (1993) except in the concept of knowledge capital. We assume that the South based imitated products do not contribute to the knowledge capital in the North. It is shown that the tightening of IPR raises the rate of innovation in the North and may improve the welfare of both North and South. These results are significantly different from those in Helpman (1993).  相似文献

This paper examines the current account dynamics in a group of ten newly industrialized countries (NICs) during the period 1980–2012 using a panel error-correction model. The model is also used to empirically test whether the degree of capital mobility is positively related to financial openness. The Chin-Ito (2006, 2008) financial openness index is used to classify the countries into different groups, and we place the countries in one group that are similar to each other in terms of their financial openness. Furthermore, to evaluate the extent of capital mobility over the different period from 1980 to 2012, the total period under study is divided into three sub-periods. The estimation results indicate that there exist long-run equilibrium relationships between domestic saving, investment, and current account in all groups regardless of their degree of financial openness. We find that more openness in terms of the capital account is associated with a higher degree of capital mobility in the case of NICs. The empirical result also indicates that the degree of capital mobility is higher in the first and third sub-period.  相似文献

Natural and man-made disasters imply a great deal of uncertainty in terms of potential damage, though it is certain that there would be a huge spike in the demand for relief supplies causing shortages and/or delays in providing aid. Ruptures in the infrastructure (roads, utility, and communication lines) cause additional delays due to repairs. Therefore, the relief providers need to work in collaboration with retailers, and infrastructure service providers for improving responsiveness. The relief providers (government and non government) rely on acquiring and delivering supplies in real time because such actions accompany little risk of resource underutilization, though the cost of real time acquisitions can be high. In contrast, a proactive response, while minimizing acquisition cost, can be very ineffective if demand surges are high. We study a hybrid of reactive and proactive approaches, where the reactive response is contingent upon the disaster intensity exceeding a certain threshold. We show how the threshold value may impact capacity acquisitions and prices and establish the optimality of contingent response. Further, we establish how an infrastructure contract may help reducing the social cost of disaster.  相似文献

Religion and identity in India’s heritage tourism   总被引:1,自引:1,他引:0  
The growing worth of heritage in the renegotiation and dissemination of identities has intensified conflicts over whose voice dominates heritage tourism representations. Therefore, this study compares the way India’s heritage is represented by the Indian government, by the domestic tourism trade media and by the popular tourism media. The findings reveal that India is consistently represented as an ethnically diverse nation in which Hinduism preceded and prevailed over all other ethnicities/religions; a portrayal that consolidates the state’s secular nationalist narrative. Furthermore, the trade and popular media emphasize nostalgic experiences of a sanitized colonial history while the government emphasizes accounts of resistance against colonial powers and of suffering due to Muslim atrocities.  相似文献

Crop management innovations are often not discrete fixed stand‐alone options—and their adoption may imply various combinations and adaptations. This potentially confounds their impact assessment. This article assesses the resource saving and productivity enhancing impacts of a crop management package revolving around minimum tillage in maize‐based farming systems in northwest Ethiopia. An endogenous switching regression model was applied to plot‐ and household‐level survey data collected from 290 rural households operating 590 maize plots during the 2012 production year. Controlling for variations in plot and household characteristics, the average effect of minimum tillage package (minimum tillage package) on maize productivity is 0.44 t/ha. Compared to conventional practice (CP), adoption of the MTP decreased the average male and female labor use in maize production by 14.4 and 8.2 person‐days per ha, respectively. Similarly, MTP adoption decreased draft power use for land preparation by 13.2 pair of oxen‐days per ha. Compared to CP, in general, there is a considerable short‐run maize productivity gain and reduction in labor and draft power use under MTP.  相似文献
