Equipment investment, output and productivity in China

At the beginning of the 1990s, J. Bradford De Long and Lawrence H. Summers highlighted in a series of influential articles that there were good reasons and quantitative evidence to support the point of view that machinery and equipment investment might be strongly associated with economic growth. China along with its enormous investment effort over recent decades constitutes an interesting case study with which to analyse the role played by equipment investment in its recent economic performance and its interaction with other sources of growth, i.e. openness, R&D, human capital and infrastructure. Our results provide evidence that equipment investment and exports are two of the most important determinants of both labour productivity and output in the long run even after controlling for other sources of growth in China. Furthermore, when human capital and infrastructure are included, the authors find that they have a positive effect on economic activity in the long run.     

Is the Export-led Growth Hypothesis Enough to Account for China＇s Growth？

One of the missing pieces preventing us from understanding recent Chinese economic development is the role played by openness and capital accumulation in this process. The question is whether the sharp economic＇ growth that the Chinese economy has experienced is another case of export-led growth due to the open-door policy or whether, on the contrary, this growth has been caused by high domestic savings and investment rates （and the consequent capital accumulation）. To answer this question, we employed an empirical framework of the cointegrated vector autoregressive model. The empirical results show that both investment （in physieal capital and R＆D） and exports, as well as the exchange rate policy, are relevant factors in explaining China＇s long-run economic growth over the past 4 decades.     

Imports and growth in China

In this paper, we analyze the role played by imports and investment on labor productivity and output in China from 1964 to 2004. In doing so, our analysis focuses on the role of technological progress incorporated into the Chinese economy through capital accumulation and imports, which could be a cause of significant technology transfer from abroad that facilitated industrialization and rapid growth in China. However, as we know that there could be other factors influencing economic development, we have also considered the role played by domestic innovation activities, competitiveness and foreign economic conditions. We focus on examining the short- and long-run effects of the considered variables as well as the direction of their causality. In addition, we investigate the role played by the exchange rate on growth and discuss some policy implications of this effect on the current debate on the appreciation of the Yuan. The empirical results provide evidence that both imports and investment encourage output and labor productivity in the long run, but neither investment causes imports nor imports cause investment. Moreover, we found that during the period considered the real exchange rate influenced output, but not productivity. These findings provide interesting insights on the future Chinese economic policy.     

Vertical specialization and intra-industry trade: The role of factor endowments

Vertical Specialization and Intra-Industry Trade: The Role of Factor Endowments. — In this paper, we use vertical differentiation models of the Falvey-Kierzkowski type to study the effects of differences in factor endowments on vertical intraindustry specialization. We focus on Spanish intra-industry trade, as Spain typically exports low-quality varieties to the northern countries of the OECD and high-quality varieties to the southern ones. In order to achieve more general results, we consider different types of productive factors: physical, human and technological capital. Our results confirm that factor endowments play a significant role in explaining vertical intra-industry specialization.     

Cooperative R&D with Endogenous Technology Differentiation

We study a nontournament R&D duopoly. Before the standard R&D investment and quantity-setting stages, we consider a stage in which firms choose their R&D technologies. Spillovers negatively depend on R&D technology differentiation. We show that, in equilibrium, firms will choose identical or very similar R&D processes. Such equilibria may entail less differentiation than would be dictated by social welfare maximization.     

War and the Corporation

Recent events have confirmed human society's commitment to building the social institutions needed for peace. It is becoming clear that these institutions will have to include business corporations.
