November 2007The Impacts of Renminbi Appreciation on Trades Flows and Reserve Accumulation in a Monetary Trade Model
with John Whalley: w13586
Given the rapidly growing reserves in Asia (China, Japan, Korea, Taiwan) and the pressures from trading partners to revalue, there is a need to examine commercial policy in more than a pure barter model. Here we evaluate the joint impacts of exchange rate appreciation on trade flows and country surpluses using a general equilibrium trade model with a simple monetary structure in which the trade surplus is endogenously determined in the exchange rate setting country and the exchange rate is exogenous. We illustrate its application to the Chinese case using calibration to 2005 data. Our results, while elasticity dependent, suggest that the impacts of Renminbi (RMB) revaluation on the surplus are proportionally larger than on trade flows, and that changes in trade flows can be substantial. Di...
Evaluating the Impure Chinese VAT Relative to a Pure Form in a Simple Monetary Trade Model with an Endogenous Trade Surplus
with John Whalley: w13581
China's VAT while seemingly conventional has two major impurities. One is that a separate export rebate system exists where rebate rates are linked from rates paid on creditable inputs. The other is the use of an income base for which there is no crediting of taxes on capital good, rather than the more conventional consumption base with expensing of investment expenditures. Here we argue that in a conventional competitive model both impurities would typically involve a welfare loss, but if we use a numerical calibrated equilibrium model with a monetary structure capturing by these Chinese features in which the trade surplus is endogenously determined and the exchange rate is exogenously set, things are different. These impurities effectively act as added taxes on domestic production (lowed...
February 2007The Unified Enterprise Tax and SOEs in China
with John Whalley: w12899
Currently proposals are actively circulating in China to move to a unified enterprise tax structure with similar tax treatment of state-owned enterprises (SOEs), other private enterprises (OPE) and foreign investment enterprises (FIEs). FIEs presently receive significant tax preferences through a sharply lower tax rate, tax holidays and other provisions. Here we use analytical representations of SOE behavior, which differ from that of the competitive firm, to argue that a unified tax structure may not be a desirable tax change and that typically a higher tax rate on SOEs is called for on efficiency grounds. Using a worker control model with endogenously determined shirking, taxes on SOEs reduce shirking and a reduced SOE tax rate under a unified tax relaxes discipline on SOEs and losses re...
