In this paper we model the pattern of international trade, and technological innovation and imitation between industrialized and developing regions, when preferences are nonhomothetic. By and large, models of the dynamics of North-South trade impose the assumption of unit income elasticity for all consumption goods. We relax this assumption and incorporate the insight from Engel’s Law: The budg...

The current low-income housing system in China is the security system giving priority to the low-rent housing and the economically affordable housing. The housing security system includes the systems and measures that the government uses the national and social power to provide the basic housing for those difficult housing groups by the transfer payment policy, and realize the equalization of t...

An LA/AIDS model is developed to estimate demand elasticities for packages of 8-oz shredded cheese for higherand lower-income consumers. Data used in this study are scanner data for six supermarket stores in two distinct socioeconomic areas. Results show that: (1) lower-income shoppers are more price-sensitive than higher-income shoppers for both private labels and national brands; (2) compared...

This paper aims to study how alternative trade policies will help mitigate the effects of climate change in agriculture in South Asia. We use a modified version of MIRAGE CGE for long term projections and allowing modeling of climate change effects (impact on yield) at a subregional level (163 geographical units at the world level) to simulate the effects of 13 SRES scenarios in 8 different tra...

In most statistical analysis, inequality or extent of variation in income isrepresented in terms of certain summary measures. But some authors arguedthat the concept of inequality is vague and thus cannot be measured as anexact concept. Therefore, fuzzy set theory provides naturally a useful toolfor such circumstances. In this paper we have introduced a real-valued fuzzymethod of illustrating t...
