Count regression models are widely used in many scientific disciplines. Nevertheless, some binary explanatory variables could be endogenous during the process of generating the count dependent variable, thus simultaneous equations bias arises. Except for some numerically intensive...

If international trade is strictly trade in intermediate goods, would the common presumption, that small, less developed economies (the South) lose from trade wars still be true? We address this question by constructing a dynamic general equilibrium model in which the North and the South trade...

The World Trade Organization (WTO) and preferential trade agreements (PTA) are key factors in international trade liberalization. However, their relative effects on trade flows are controversial (ranging from 16 percent to 277 percent), depending on whether the endogeneity of these two variables...

To answer whether capital mobility exacerbates or dampens the agglomerative tendency of footloose entrepreneurs, this paper incorporates a footloose-capital with a footloose-entrepreneur manufacturing industry based on a tractable analytical structure with two identical regions. The model shows...

To examine the effects of heterogeneous labor mobility on the distribution of industries and analyze the subsidy policy for attracting firms, this paper develops an analytically solvable new economic geography model, which incorporates heterogeneous locational preferences and an intra-industry...

To explain the spatial selection of vertically di fferentiated firms, this paper incorporates heterogeneous preferences and heterogeneous quality productions into a framework of the footloose capital model, in which labor is immobile. In two regions with identical population size, when trade...

This paper aims to fill the gap between theoretical and empirical studies of home market effects (HMEs). On one hand, empirical studies on the price aspect of HMEs -- that wages are higher in larger markets -- are supportive, but studies on the quantity aspect -- that the firm share in the...
