Input Prices, Productivity, and Trade Dynamics: Long-Run Effects of Liberalization on Chinese Paint Manufacturers

We develop a dynamic model to analyze the impact of input tariff liberalization on input prices, trading decisions, and productivity. Although input tariffs directly affect input price benefits of importing, their impact on trade participation generates indirect benefits through productivity improvements and complementarity between importing and exporting. To disentangle these effects, we separately measure importing's effect on input prices and productivity and examine Chinese paint manufacturers' reaction to input tariff liberalization. We find that a mild short-term effect of tariff liberalization is amplified in the long run by induced trade participation, resulting in even higher productivity and lower input prices.

Does External Monitoring from the Government Improve the Performance of State-Owned Enterprises?

In this paper we investigate the impact of external monitoring from the government on state-owned enterprise performance, using the variation in monitoring strength arising from a nationwide policy change and firms’ geographic location in China. We utilise a structural approach to estimate input prices and productivity separately at the firm level using commonly available production data. We show that enhanced external monitoring, as a key component of corporate governance, can substantially reduce managerial expropriation in procurement (proxied by input prices) and shirking in production management (proxied by productivity). The results suggest that government monitoring can be an effective policy instrument to improve state-owned enterprise performance.

Does External Monitoring from Government Improve the Performance of State-Owned Enterprises?

Dr Hongsong Zhang of HKU Business School and Dr Shengyu Li of University of New South Wales discussed in this VoxChina piece their investigation of the impact of external monitoring from the government on state-owned enterprise performance, using the variation in monitoring strength arising from a nationwide policy change and firms’ geographic location in China. We utilize a structural approach to estimate input prices and productivity separately at the firm level using commonly available production data. We show that enhanced external monitoring, as a key component of corporate governance, can substantially reduce managerial expropriation in procurement and shirking in production management. The results suggest that government monitoring can be an effective policy instrument to improve state-owned enterprise performance.

What You Import Matters for Productivity Growth: Experience from Chinese Manufacturing Firms

This paper investigates the distinct effects of capital and intermediates imports on firms' productivity growth, and quantifies the importance of tariff structure in trade liberalization in developing countries. Using a large panel of Chinese manufacturing firms, we demonstrate that capital import has a substantially larger productivity effect than intermediates import. On the one hand, while both types of imports exert immediate effects on productivity, only capital import has dynamic productivity effects. On the other hand, we identify significant R&D-capital synergy effect and R&D-inducing effect from capital import, but there is no clear evidence of these effects from intermediates import. Regarding the effects of China's input tariff liberalization following its WTO accession, the change in tariff structure explains 18 percent of the productivity gains.

Productivity or Unexpected Demand Shocks: What Determines Firms’ Investment And Exit Decisions?

We investigate the roles played by unexpected demand shocks, besides productivity, on firms' capital investment and exit decisions. We propose a practical approach to recover unexpected firm‐level demand shocks using inventory data. The recognition of demand shocks and inventory also improves the productivity estimation. The empirical results indicate that although productivity and demand shocks are both significant factors determining firm behavior, the former is more dominant for investment decision and the latter is more salient for firm exit. These findings confirm that unexpected demand shocks, besides persistent productivity, are important factors when analyzing capital investment and firm exit decisions.
