China's emergence as a major player in world trade is well known, but its growing role in global finance might have been underappreciated. China is the second largest creditor in the world today, with a net creditor position of 30 percent of GDP in 2008. We test the importance of the growth...

The impact of international trade is studied in a general equilibrium model in which firms engage in oligopolistic competition and linkage effects are present. Results are derived analytically. If countries have the same technologies and the same labor endowment, core-periphery pattern arises...

Is the degree of external economies (at the industry level) higher than the degree of internal increasing returns (at the firm level)? If so, what is the exact source of this difference? In the general equilibrium model in which firms producing final goods choose the degree of specialization of...

This paper studies a general equilibrium model of rural-urban migration in which manufacturing firms engage in oligopolistic competition and choose increasing returns technologies to maximize profits. Urban residents incur commuting costs to work in the Central Business District. Surprisingly a...

The Confucian school emphasizes family value, moral persuasions, and personal relations. Under Confucianism, there is a free-rider issue in the provision of efforts. Since national officials are chosen through personal relations, they may not be the most capable. The Legalist school emphasizes...

In this general equilibrium model, banks and manufacturing firms engage in oligopolistic competition. A more advanced manufacturing technology has a higher fixed cost but a lower marginal cost of production. We show that manufacturing firms located in a country with a more efficient financial...

This paper studies impacts of factor endowment on international trade in a general equilibrium model in which firms choose their technologies endogenously. Although countries only differ in factor endowment ex ante, countries may also differ in their chosen technologies. If industries choose...

This paper studies a Ricardian model of international trade with a continuum of products in a general equilibrium model in which firms engage in oligopolistic competition. It provides a bridge between trade models based on perfect competition and models based on imperfect competition. Compared...
