The volatility trade-offs (i.e. the negative relationships between exchange rate variability and the interest rate differential) exhibited in the Krugman [Krugman, P. (1991). Target zones and exchange rate dynamics. Quarterly Journal of Economics, 106, 669-682.] model depend on the assumption of...

By incorporating a keeping-up-with-the-Joneses preference into the Redux model, this paper sketches the implications of consumption externalities for the short-run and long-run equilibria. We show that the size of the consumption externality plays a crucial role in terms of affecting the...

This paper analyzes the relationship between interest-rate feedback rules and macroeconomic stability in the presence of transaction costs. We show that with the Sims-type (1994) transaction-cost technology, a passive, rather than an active, interest-rate rule is more likely to generate a...

This paper develops a monopolistic competition macroeconomic model, and uses it to discuss the determination of relevant macro variables under both vertical separation and vertical integration regimes. Several main findings emerge from the analysis. First, in the market equilibrium aggregate...

Using a general-equilibrium framework, this paper examines the price dynamics of a monetary shock for a small open economy with commodity spot and futures markets. The agricultural spot price can fall by exhibiting a mis-adjustment at the instant of the announcement of the increase in the money...

This paper sets up a modified Mundell-type economy embodying a New Keynesian “forward-looking” exchange-rate and output expectations, and develops a graphical exposition to explain the conflicting outcome between Krugman's (1991) prediction and the empirical observations in the regime of...

This paper develops an endogenous growth model with a production externality and nonlinear income taxation, and uses it to examine how the fiscal authority devises its nonlinear tax structure from the viewpoint of welfare maximization. It is found that, in the Barro (1990) model, Pareto...

This paper develops an endogenous growth model to examine the linkages between environmental consciousness and economic growth. It is found that macroeconomic instability can arise in a simple AK-type growth model when the pollution externality is present only in the agent's utility function. It...

The collapsing scenario of Easter Island has been analyzed by Brander and Taylor (1998) as a predator–prey model in a Malthusian world, in which the household is only concerned with its instantaneous utility. This paper develops an endogenous growth model with a renewable resource and analyzes...
