Welfare Effects of Tax Policy in Open Economies: Stabilization and Cooperation.

This paper studies optimal tax policy design problem by employing a two-country dynamic general equilibrium model with incomplete asset markets. We investigate the possibility of welfare-improving active, contingent tax policies (tax rates respond to changes in productivity) on consumption, and capital and labor income taxes. Unlike the conventional wisdom regarding stabilization policies, procyclical factor income tax policy is optimal in open economy. Procyclical tax policy generates efficiency gains by correcting market incompleteness. Optimal tax policy under cooperative equilibrium is similar to that under the Nash equilibrium and welfare gains from tax policy coordination is quite small.optimal tax, procyclical, countercyclical, stabilization, cooperation.

Spurious Welfare Reversals in International Business Cycle Models

Several papers on international business cycles have documented spurious welfare reversals, in that incomplete market economies can produce higher welfare than the complete market economy. This paper demonstrates how conventional linearization, as used in King, Plosser, and Rebelo (1988), can generate approximation errors that are large enough to result in such reversals. Using a two-country production economy without capital, we argue that spurious welfare reversals are not only possible but also plausible under reasonable parameter values. As a constructive alternative, this paper proposes an approximation method that modifies the conventional linearization method by a bias correction---the linear approximation around a 'stochastic' steady state. We show that this method can be easily implemented to accurately approximate the exact solution and therefore produce the correct welfare ordering. The accuracy of the proposed method is far better than that of the conventional linearization method and as good as that of a method involving a second-order expansion.Linearization, Stochastic steady state, Welfare, Risk sharing

Welfare Effects of Tax Policy in Open Economies: Stabilization and Cooperation

This paper studies optimal tax policy problem by employing a two-country dynamic general equilibrium model with incomplete asset markets. We investigate the possibility of welfare-improving active, contingent tax policies (under which tax rates respond to changes in productivity) on capital and labor income and consumption. Unlike the conventional wisdom regarding stabilization policies, procyclical factor-income tax policies in general improves welfare in open economies. Procyclical tax policies generate efficiency gains by correcting asset market incompleteness. Optimal tax policy under cooperative equilibrium is similar to that under the Nash equilibrium, and welfare gains from tax policy coordination is quite smalloptimal tax, procyclical, countercyclical, stabilization, cooperation

International Capital Flows and Boom-Bust Cycles in the Asia Pacific Region

This paper documents evidence of business cycle synchronization in selected Asia Pacific countries in the 1990s. We explain business cycle synchronization by the channel of international capital flows. Using the VAR method, we find that most Asian countries experience boom-bust cycles following capital inflows, where the boom in output is mostly driven by consumption and investment. Empirical evidence shows that capital flows in the region are highly correlated, which supports the conclusion that capital market liberalization has contributed to business cycle synchronization in Asia. We also find that business cycles in the Asian crisis countries are highly synchronized with those in Japan.business cycle synchronization, capital flows, boom-bust cycles, financial integration

Fear of Floating in East Asia

We examine the de facto exchange rate arrangements in East Asia by applying the methods suggested by Calvo and Reinhart (2002) and Kim (2004). Estimation results suggest that three East Asian countries in our sample adopted a hard peg or a peg with capital account restrictions in the post-crisis period. Five East Asian countries in our sample moved toward a more flexible exchange rate arrangement in the post-crisis period. At least three of these five countries (Korea, Indonesia and Thailand) achieved the level of exchange rate flexibility that is close to the level accomplished in the free floater such as Australia. These results suggest that “Fear of Floating” of East Asian countries is not prevalent in the post-crisis period and that the bi-polar view has some support in East Asian samples.Bi-polar View, De Facto Exchange Rate Arrangements, De Jure Exchange Rate Arrangements, East Asia, Fear of Floating
