Market For Patents, Monopoly, And Misallocation, Shang-Jin Wei, Jianhuan Xu, Ge Yin, Xiaobo Zhang

The paper studies a possible “dark side” of patent trade in enhancing the market power of monopolists. We explore the different effects of China’s 2008 tax reform on patent innovations and sales across industries. In particular, although easier patent trade leads to more patent creation, the new patents are disproportionately connected to existing monopolists and are more likely to be acquired by them. Using an endogenous growth model with patent trade, we show that subsidizing patent trade could skew investors’ research to appeal to the monopolists, increase the latter’s monopoly power, and reduce social welfare. An optimal subsidy policy for …


Migration And Spatial Misallocation In China, Xiaolu Li, Lin Ma, Yang Tang Apr 2023

Migration And Spatial Misallocation In China, Xiaolu Li, Lin Ma, Yang Tang

We structurally estimate the firm-level frictions across prefectures in China and quantify their aggregate and distributional implications. Based on a general equi-librium model with input and output distortions and migration, we show that the firm-level frictions are less dispersed and less correlated with productivity in richer prefectures. Counterfactual exercises show that reducing the within-prefecture mis-allocation increases the aggregate welfare, discourages migration towards large cities, and narrows the spatial inequality. Moreover, internal migration alleviates the impacts of micro-frictions on aggregate welfare and worsens their impacts on spatial inequality.
