In this study, we employ a recently developed econometric technique of the threshold model with the GJR-GARCH process on error terms to investigate the relationships between weather factors and stock market returns in Taiwan using daily data for the period of 1 July 1997–22 October 2003. The major weather factors studied include temperature, humidity, and cloud cover. Our empirical evidence sho...

Recently, Starns et al. (2008) collected source judgments for old items, which participants had claimed to be new, and found residual source discriminability depending on the old-new response bias. The finding was interpreted as evidence in favor of the multivariate signal-detection model but against the high-threshold model of source memory. According to the latter, “new” responses only follow...

CONTEXT Major depressive disorders are frequently underdiagnosed and undertreated. Collaborative Care models developed from the Chronic Care Model during the past 20 years have improved the quality of depression management in the community, raising intervention cost incrementally above usual care. This paper assesses the economic efficiency of collaborative care for management of depressive dis...

Abstract Achieving economic growth, as one of the essential purposes in each country, needs appropriate tracing of government as one of the important and effective sections in that economy. Nowadays, unlike the 80s, economists concentrate on objectives such as explanation of the relationship between size of the government and economic growth and delineation of optimum size of the government w...

In this paper, we propose a semi-parametric approach to estimate threshold models without the reliance of distribution assumption when the threshold variable is endogenous. Early threshold models based on the exogeneity assumption on the threshold variables are widely applied in economics studies. The invalidation of this assumption, however, may bias the estimation and inference. To control fo...
