Innovation plays a key role in economic growth. In this paper, we investigate the effects of intermediate input tariff reduction on the innovation activities of domestic firms. Input tariff reduction has two opposite effects on the innovation decision of a firm: it may promote innovation because...

This paper provides a theoretical and empirical analysis of the effects of one-sided tariff cuts on firms' export product scope. The theoretical model explicitly incorporates cost of management in addition to the commonly used production cost. Firms are heterogeneous in terms of managerial...

Evidence shows that most foreign direct investment (FDI) flows from developed to developed countries (North–North) in skilled labor-intensive industries. This paper builds a model that incorporates labor training into the proximity–concentration tradeoffs to analyze the entry mode of...

A model of heterogeneous firms with variety-specific fixed costs is developed and analyzed to study how multiproduct firms respond to globalization. In contrast with most existing models, the analysis demonstrates that more-productive firms may expand their product scope, which in turn may push...

This paper develops a two-country, two-firm model to study equilibrium lobbying positions in intra-industry trade. A firm chooses either a protectionist position or a free-trade position. The model predicts that taking the free-trade lobbying position is an efficient firm's dominant strategy. If...

We develop a North-South model of international trade and transboundary pollution to analyze the relationship between environmental technology transfer and the South's incentive to join an international environmental agreement (IEA). We find necessary and sufficient conditions under which...
