We consider nonsmooth multiobjective fractional programming problems with inequality and equality constraints. We establish the necessary and sufficient optimality conditions under various generalized invexity assumptions. In addition, we formulate a mixed dual problem corresponding to primal problem, and discuss weak, strong and strict converse duality theorems.

D evelopment of social and economic infrastructure in every region is of the basic requirements of economic growth. Infrastructure stimulates economic activity, enhance the productivity of private sector’s inputs, improve economic performance and thus sustainable economic development, enhancing the social welfare and better income distribution. Since the different kind of infrastruct...

UNRISD’s recent publication, Combating Poverty and Inequality, attempts to explain how poverty reduction depends crucially on the interconnections among economic development, social policy and politics. It emphasizes that poverty and inequality cannot be addressed by narrow approaches to social protection or by economic growth alone. Instead, there is a need for new directions in macroeconomic ...

After around twenty years of neglect, inequality has been brought out of the cold. Inequality has re-entered the mainstream development policy agenda by featuring prominently in the World Bank’s World Development Report 2000/01. Inequality matters in its own right (see Inequality Briefing No 1) and it is key to reducing poverty. This paper draws on recent research to explore in what ways inequa...

The paper revisits the debate on trickle-down growth in view of the widely discussed evolution of the earnings and income distribution that followed a massive expansion of higher education. We propose a dynamic general equilibrium model to dynamically evaluate whether economic growth triggered by an increase in public education expenditure on behalf of those with high learning ability eventuall...

There has been a growing concern with the adverse impacts of economic development upon the environment in recent years and a concomitant response in terms of policy initiatives. The policy discourse of sustainable development proposes that economic development and the environment can be integrated to give rise to “win-win” outcomes. Many policy initiatives have been developed at the urban, regi...

The non-Marxist, or neo-Malthusian, approach to the study of population problems is criticized, with particular reference to the situation in Africa. An alternative Marxist approach is proposed in which the solution to population problems is sought either in revolution or radical improvements in social welfare involving the maximum egalitarian distribution of the benefits of social and economi...

This paper uses an encompassing framework developed by Murphy et al. (1991, 1993) to study corruption and how it affects income distribution and growth. We find that (1) corruption affects income distribution in an inverted U-shaped way, (2) corruption alone also explains a large proportion of the Gini differential across developing and industrial countries, and (3) that even after correcting f...
