Customer Capital And Trade Intermediaries: Evidence From China, Jungho Lee, Jianhuan Xu
Customer Capital And Trade Intermediaries: Evidence From China, Jungho Lee, Jianhuan Xu
Research Collection School Of Economics
Using a unique dataset that links the production and sales of Chinese exporting firms, we document that the value of export goods a firm produces often differs from the value of export goods that the firm sells in foreign markets. We show that this empirical pattern reflects that some exporters act as trade intermediaries, which we refer to as producer intermediaries. We further show that firms with higher accumulated marketing expenditures are more likely to become producer intermediaries. To understand the implications of our empirical findings, we develop a theoretical framework in which firms can lend and borrow customer capital …
Estimating The Benefits And Costs Of Forming Business Partnerships, Jungho Lee
Estimating The Benefits And Costs Of Forming Business Partnerships, Jungho Lee
Research Collection School Of Economics
I estimate a matching model of business‐partnership formation to quantify the relative importance of productivity gains, financing gains, and the coordination failure of effort provision (moral hazard) among partners. Productivity gains account for 61% of the gain from the observed partnerships. For partners in the first quartile of the wealth distribution, however, financing accounts for 93% of the gain. The cost of moral hazard corresponds to 42% of the entire gain from partnerships. A loan policy specifically targeting partnerships is less effective in improving welfare than a conventional loan policy that provides loans to individual entrepreneurs.

Recently Martins-Filho and Yao (J Multivar Anal 100:309–333, 2009) have proposed a two-step estimator of nonparametric regression function with parametric error covariance and demonstrate that it is more efficient than the usual LLE. In the present paper we demonstrate that MY’s estimator can be further improved. First, we extend MY’s estimator to the multivariate case, and also establish the asymptotic theorem for the slope estimators; second, we propose a more efficient two-step estimator for nonparametric regression function with general parametric error covariance, and develop the corresponding asymptotic theorems. Monte Carlo study shows the relative efficiency loss of MY’s estimator in …

We investigate the role of education on worker productivity and firms' total factor productivity using a panel of firm-level data from China. We estimate the returns to education by calculating the marginal productivity of workers of different education levels based on estimates of the firm-level production function. We also estimate how the education level of workers and CEO contributes to firms' total factor productivity. Estimated marginal products are much higher than wages, and the gap is larger for highly educated workers. Our estimate shows that an additional year of schooling raises marginal product by 30.1%, and that CEO's education increases …
