Strategic tariffs, tariff jumping, and heterogeneous firms

The majority of research to date investigating strategic tariffs in the presence of multinationals finds a knife-edge result where, in equilibrium, all foreign firms are either multinationals or exporters. Utilizing a model of heterogeneous firms, we find equilibria in which both pure exporters and multinationals coexist. We utilize this model to study the case of endogenously chosen tariffs. As is standard, Nash equilibrium tariffs are higher than the socially optimal tariffs. Unlike existing models with homogeneous firms, we find that non-cooperative tariffs promote the existence of low-productivity firms relative to the socially optimal tariffs. This highlights a new source of inefficiency from tariff competition not found in models of homogeneous firms. In addition, we find that in many cases the Nash equilibrium tariff when FDI is a potential firm structure is lower than when it is not. As a result, FDI improves welfare by mitigating tariff competition.     

Choose to Fight or Choose to Flee? A Network Embeddedness Perspective of Executive Ship Jumping in Declining Firms

Research summary: Executives in declining firms may engage in ship‐jumping behavior (i.e., voluntarily move to new employers before the failure occurs) to avoid the stigma of failure. However, it is unclear how executives decide whether or not to jump ship. Building on a network embeddedness perspective, we highlight how three network‐based indicators (i.e., executive social capital, the social capital of other peers in the declining firm, and the declining firm's alliance network) influence the executive‐level ship‐jumping decision by shaping its benefits and opportunity costs. Using data from executives at failing firms in China, we find support for our hypothesized relationships. Our research provides important insight into the network mechanisms driving the ship‐jumping decision. Managerial summary: Executives at failing firms have a choice: stay and attempt to rescue the firm from failure or exit and avoid the stigma of the failure (i.e., jump ship). Yet, little is known about what factors affect this choice. We propose that social capital plays an important role in the decision. Our evidence from specially treated (*ST) public firms in China finds that ship jumping is lowest at low and high values of social capital, and highest at moderate levels of social capital (an inverted U‐shaped relationship). In addition, higher levels of peer social capital (in the declining firm) as well as a well‐established firm‐level alliance network discourage the ship‐jumping choice.

我国中小企业跳跃式的国际化进程模式探讨

按照传统的北欧学派企业国际化理论以及邓宁的折中理论,企业的国际化进程是企业规模由小及大、心理距离和地理距离由近及远、循序渐进的阶段式过程.但当今世界经济一体化的大环境,网络信息技术的高度发展,使市场范围扩大化,地理距离弱化.我们应从产品生命周期理论入手,借鉴国外成功经验,我国中小企业应采用跳跃式的国际化进程模式,加快参与国际竞争步伐,尽快形成我国中小企业跳跃式的国际化进程模式.

国外对华反倾销的贸易转移效应分析——以美国为例

随着中国经济的发展和对美出口的持续增长,中国成为遭受美国反倾销诉讼最多的国家,反倾销已成为中美经贸关系健康发展的一大实质性障碍。美国对华反倾销存在着一定的贸易转移效应,尤其体现在遭受反倾销诉讼最多的钢铁产业及其他各产业的涉案产品上,对中国出口企业造成很大的损害。中国一方面要维系良好的中美贸易伙伴关系,另一方面要规避反倾销的贸易转移效应,主动寻找出口市场,实现出口市场的多元化,同时充分实施"走出去"战略,通过对美直接投资跨越贸易壁垒。
