Integration of National Complex and Sports Techniques: A View on the Historical Media of the Chinese Martial Arts from Unification of Martial Arts (1934-1935)

The Unification of Martial Arts was an important publication about martial arts during the period of the Republic of China. As a media for communication, it exerted a huge positive impact on spreading traditional Chinese martial arts in its ways and the contents. Therefore, this paper explores this journal through the method of literature and logic analysis. The study finds that, in terms of the content spreading, Unification of Martial Arts mainly has analyzed the martial arts from its unified concept, its ambitious thought of building China into a powerful nation, the basic knowledge of martial arts, its history and the legendary stories related to it. In terms of the ways, photographs have become an important carrier of martial arts techniques and a way of expressing national complex. The communication and investigation have presented the readers with a learning platform for interaction. Meanwhile, the dissemination of information about other sports has broken through the limitation in martial arts communication, demonstrating the inclusive spirit in the sporting world

A Model of Trade with Ricardian Comparative Advantage and Intra-sectoral Firm Heterogeneity

In this paper, we merge the heterogenous firm trade model of Melitz (2003) with the Ricardian model of Dornbusch, Fisher and Samuelson (DFS 1977) to explain how the pattern of international specialization and trade is determined by the interaction of comparative advantage, economies of scale, country sizes and trade barriers. The model is able to capture the existence of inter-industry trade and intra-industry trade in a single unified framework. It explains how trade openness affects the pattern of international specialization and trade. It generalizes Melitz’s firm selection effect in the face of trade liberalization to a setting where the patterns of inter-industry trade and intra-industry are endogenous. Although opening to trade is unambiguously welfare-improving in both countries, trade liberalization can lead to an counter-Melitz effect in the larger country if it is insufficiently competitive in the sectors where it has the strongest comparative disadvantage but still produces. In this case, the operating productivity cutoff is lowered while the exporting cutoff increases in the face of trade liberalization. This is because the intersectoral resource allocation (IRA) effect dominates the Melitz effect in these sectors. Consequently, the larger country can lose from trade liberalization. Some hypotheses related to firms’ exporting behavior across sectors upon opening up to trade and upon trade liberalization are also derived. Analyses of firm-level data of Chinese manufacturing sectors confirm these hypotheses.inter-industry trade, intra-industry trade, heterogeneous firms, trade liberalization

Firm Dynamics in News Driven Business Cycle: The Role of Endogenous Survival Rate

Our structural VAR shows that the new business formation in U.S. data has similar positive co-movement pattern as common aggregate variables in response to a favorable anticipated shock about technology. However, incorporating �firm dynamics into Jaimovich and Rebelo's (Jaimovich and Rebelo, 2009, American Economic Review) model cannot explain our empirical fi�nding. Even worse, the model predicts an aggregate recession instead of a boom. Then, we show that this problem can be resolved with a minor modification by introducing endogenous survival rate of the new entrants

How Minimum Wages affect Automation and Innovation in a Schumpeterian Economy

This study explores the effects of minimum wage on automation and innovation in a Schumpeterian growth model. We find that raising the minimum wage decreases the employment of low-skill workers and has ambiguous effects on innovation and automation. Specifically, if the elasticity of substitution between low-skill workers and high-skill workers in production is less (greater) than unity, then raising the minimum wage leads to an increase (a decrease) in automation and innovation. We also provide a quantitative analysis by simulating the effects of minimum wage on the macroeconomy. Finally, we test our theoretical results by estimating the elasticity of substitution between low-skill workers and high-skill workers and the effects of minimum wage on automation and innovation in China

Firm Dynamics in News Driven Business Cycle: The Role of Endogenous Survival Rate

Evidences from structural VAR show that new business formation positively co-moves with output under news shocks. The Jaimovich-Rebelo model augmented with firm dynamics can explain the empirical findings. The key assumption is endogenous survival rates for new entrants
