Climate change makes extreme droughts more frequent with heavy economic losses in China, thus this study aims to evaluate China's regional vulnerability to drought and propose proper mitigation strategies for drought-vulnerable areas. In this paper, an integrated index containing exposure,...

We develop an evolutionary algorithm to estimate Threshold Vector Error Correction models (TVECM) with more than two cointegrated variables. Since disregarding a threshold in cointegration models renders standard approaches to the estimation of the cointegration vectors inefficient, TVECM...
