In this paper, we consider a finite-horizon model with the time-additive utility and the time varying discount rate. With the assumption of the concavity of absolute risk tolerance, the concavity of the consumption function has been proved. This result significantly broadens the conclusion of...

Theory suggests that a close match between revenue and expenditure assignments at sub-national levels benefits allocative efficiency, and hence economic growth. That is, a convergence of revenue and expenditure assignments at sub-national levels of government should, according to the theory, be...

This paper investigates the relationship between optimal monetary and tariff policy in open economies. In producer-currency pricing (PCP) case, as in Obstfeld and Rogoff (2002), optimal tariff policy rules are separable from optimal monetary policy rules. Except for PCP case, they are not...

In this paper, we study the effects of fiscal policies on economy in a stochastic model with hyperbolic discounting rate. With specific assumptions on the production technology, preferences, and stochastic shocks, we derive the explicit solutions to the growth rates of consumption and savings...

This paper examines optimal monetary policy rules in open economies with vertical production and trade in which we emphasize the role played by reference currency. As evidenced by empirical ï¬ndings, we assume ï¬nal goods prices are sticky, but intermediate goods prices are flexible. We...

The paper studies fiscal policy, monetary policy and the exchange-rate theory in a Viner-Zou monetary model of mercantilism. It is shown that, except for government consumption, permanent increases in the mercantilist sentiments, monetary growth rate, consumption tax, and foreign exchange...
