China's value-added tax reform, capital accumulation, and welfare implications

This paper analyzes the effects of China's upcoming value-added tax (VAT) reform of removing investment from the tax base on capital accumulation and the welfare of the rich and the poor. Three alternative methods to make up for the loss of tax revenue are considered. The VAT reform with consumption tax being endogenous increases capital accumulation and the utility of both the rich and the poor. The VAT reform with the labor income tax rate being endogenous increases capital accumulation; and it decreases the utility of the rich and increases the utility of the poor (increases the utility of both the rich and the poor) if the rich has a higher rate or the same rate of time preference (if the rich has a lower rate of time preference). The VAT reform, accompanied by a cut in transfers to the poor, has no effect on capital accumulation if the rich and the poor have the same rate of time preference; it decreases (increases) capital accumulation if the rich has a higher (lower) rate of time preference; and it increases the utility of the rich and decreases the utility of the poor.     

Foreign Transfers and Real Exchange Rate Adjustments in a Financially Constrained Dependent Economy

This paper investigates the role of the real exchange rate in determining the effects of foreign transfers. If capital is perfectly mobile between sectors, a pure transfer has no long-run impact on the real exchange rate. A decline in the traded sector occurs because the transfer, being denominated in traded output, substitutes for exports in financing imports. While a pure transfer causes short-run real exchange appreciation, this response is temporary and negligibly small. Transfers allocated to productivity enhancement do generate permanent real exchange rate adjustments in response to the sectoral reallocation of productive factors. The analysis, which employs extensive numerical simulations, emphasizes the tradeoffs between real exchange adjustments, long-run capital accumulation, and economic welfare, associated with alternative forms of transfers.

On the existence of single-price equilibria in a matching model with divisible money and production cost

The present paper investigates Zhou's (1999) money search model, where money is divisible, agents can hold any amount of money and production of goods is costly, and presents a sufficient condition, expressed in terms of exogenously given parameters, for the existence of single-price equilibria.     

Commitment and coordination in a dynamic game model of international economic policy-making

In this paper, we consider a dynamic game model of two identical countries. Policy-makers of both countries have quadratic intertemporal objective functions and want to stabilize domestic output, domestic inflation, and the real rate of exchange. We present different analytical and numerical solutions for this policy game. Noncooperative open-loop equilibria are interpreted as requiring unilateral commitment and policy-makers' credibility. Potential gains from cooperation are present, as the noncooperative equilibrium solutions are not Pareto-optimal. Under an information pattern that admits memory strategies, the possibility of obtaining cooperative results without coordination and commitment arises.     

External debt,time preference,and nontraded goods in a two-sector dynamic model of consumption

A number of studies have indicated that one of the consequences of a development process is a rise in the consumers' subjective time preference rate (discount rate). This study first shows that many of the adverse economic observations in developing countries can emerge from a rise in the discount rate. It then demonstrates that the extent of such adverse effects is related to relative shares of the tradable and nontradable sectors in aggregate consumption. A result is that the aggregate dissaving generated by a rise in the discount rate is smaller when the economy's nontradable sector is relatively larger. The results add new dimensions to the allocation policies applied by international lending insitutions in developing economies.
