We present some Farkas-type results for inequality systems involving finitely many DC functions. To this end we use the so-called FenchelLagrange duality approach applied to an optimization problem with DC objective function and DC inequality constraints. Some recently obtained Farkas-type results are rediscovered as special cases of our main result.

We provide an historical survey of Chinese economic reform, a discussion of the current major problems, and measures of the evolution of inequality in China through time, 19791996.We argue that China’s most pressing reform needs now are in the social sphere, specifically the creation of an adequate social security system. The paper concludes with maps showing measures of inequality within each ...

Much controversy has developed recently over capital formation and the claim that the eocial security system has reduced savings and a3 a reeult the potential for economic growth in this country. Concerned that there was much misunderstanding with respect to the subject, the Comm483ioner of Social Security asked the Ofice of Reeearch and Statietics to make a presentation to top-level stag to cl...

This paper is the first attempt in the literature to investigate the effects of public social security on aggregate consumption in a time-series setting for a developing country, Turkey that has one of the most generous social security systems in the OECD region. In order to quantify the social security variable, the paper uses the social security wealth (SSW) series calculated for Turkey in a ...

Huang School of Management, Fudan University, Shanghai 200433, China Abstract. In this paper, we apply the quadratic penalization technique to derive strong Lagrangian duality property for an inequality constrained invex program....
