Jinjing Tian, IAER Assistant Professor, published her paper in The World Economy in April 2021. Entitled "The Effect of Exports on Labour Share: A Semiparametric Approach Using Chinese Manufacturing Panel Data", the paper was co-authored with Taining Wang, Assistant Professor at Capital University of Economics and Business, and Joshua Hall, Professor at West Virginia University.
The paper distinguishes the effects of export on labour share into a stand-alone direct effect and indirect effects, which alter the marginal impact of three key determinants of labour share found in the literature. While the direct effect of export has been extensively studied, the potential indirect effects remain unexplored. The paper investigates both effects of exports using micro-level Chinese firm-level data from 1998 to 2007. A fixed-effect varying coefficient model is employed to reveal the potential nonlinearity of the effects of exports while alleviating the risk of model mis-specification. The model is estimated by a spline backfitted kernel estimator, which is more efficient and computationally attractive than alternative estimators. The paper finds that while exports directly increase labour share as expected, it declines labour share indirectly through intensifying the negative marginal impact of firms' capital intensity, monopoly power and capital-augmented technological progress on labour share. As a result, the net effect of exports is not beneficial to labour's share of income and varies in magnitude across firm characteristics, regions and time periods.
