Property Rights, Inefficient Investment and Deflation

This paper develops a property rights framework for the analysis of inefficient investment expansion in China. It argues that the ambiguity of land transfer rights and incompleteness of banks' property rights have profound impact on the behavior of investment. Pursuing their political promotion, local government officials have incentive to encourage investment by transferring land to firms at the cost lower than market price. Because of the incompleteness of property rights constraint, the banks also intend to provide finance support for such investment without paying enough attention to the possibility of NPLs. These factors considerably lower the private investment cost for rational investors without accounting for the high social costs, which result in an over expansion of investment. Consequently, over investments lead to over capacity, which lead to deflation.
