Cross entropy is used to estimate the Almost Ideal Demand System for consumption in Greece. The entropy estimates are found to improve upon the SUR estimates. It is recommended that practitioners consider employing entropy based procedures in systems where the data set is small, where there are a large number of parameters, or where the data are deficient. 相似文献
Summary The article gives a physical-economic interpretation to a number of economic North-South interdependent relations. Basic research evidence at the man-machine level was an inspiration; the output could only be expressed in physical specification terms. The corresponding generalizations are in product complexity, speciality terms also. This terminology is conducive to far-ranging extrapolations and generalizations. It eliminates the problem of pricing at the product level for all aggregation levels; therefore the fundamental economic relations are better expressed. The article concludes with a mega extrapolation in graphical terms, which relates the product and implied technological capability in the world, expressed in physical terms, for country groups ordered by three development levels. Correspondingly the comparative advantage and inter-industry trade areas at the world product level are shown.The author acknowledges valid comments of two anonymous referees and financial support by DGIS to the Technology Scientific Foundation for the research of which this paper reports certain aspects only.

This study uses unit-record data on over 50,000 rural children, from the sixteen major states of India, to analyse the determinants of the risks of severe stunting and of being severely underweight. The importance of this study derives from the fact that the prevalence of under-nourishment in India is, even relative to other poor countries, shockingly high. The study focuses on the role of maternal literacy in reducing the risk of child malnourishment. It concludes that when the mother is literate, real benefits flow to children in terms of reduced risk; the same benefits, however, do not flow when the father, but not the mother, is literate. Literate mothers make more effective use of health-care institutions, like anganwadis and hospitals. Consequently, the benefits to children from expanding the supply of such institutions are greater when these institutions interact with mothers who are literate.
This paper attempts to survey the recent literature on the impact of stabilization and adjustment programs upon the poor and to consider some of the key issues in the context of a particular equity-oriented low-income country. Tanzania. After looking at some of the approaches of earlier studies, this paper analyzes the effects of restructuring policies, macroeconomic restraint, and strategic policy change. The author then reviews available evidence on the recent experience of Tanzania with external shock, efforts at stabilization, and relations with the IMF.In conclusion, the author argues that in order to better understand their impact on poverty we need more detailed analyses of specific countries' experience with different kinds of macroeconomic imbalance and different short- to medium-term policy responses. However, he does indicate with some certainty that when equivalent external blows impact upon very low-income countries, there must be a presumption that, other things being equal (including the distribution of income), the proportion of households and people pushed over the line into “absolute poverty” will be greater than in middle-income countries. The international community should provide external finance to aid these low-income countries in limiting the negative impact on the poorest. 相似文献
