Internationalization of the Korean Won in the Light of the RMB Internationalization
While China has risen to become a global superpower with a growing impact on the world economy, its currency, the Renminbi (RMB), has a limited role in the existing international financial system. China has made significant progress and will continue to push for the internationalization of the RMB, which can disrupt the global financial system, dominated by the US dollar. Under such circumstances, Korea must find a new direction for the internationalization of the Korean Won. The internationalization of the Korean won will provide new opportunities for the economy to take a further step through financial advancement.
Macroeconomic Effects of Capital Account Liberalization
The macroeconomic effects of capital account liberalization in Korea are examined. Simple data analysis suggests that capital account liberalization substantially changed the nature and composition of capital flows. Based on the VAR model, the authors find the following stylized facts. First, after capital market liberalization, capital flows become less driven by current account imbalances and therefore become more autonomous. Second, capital account liberalization significantly changes the effects of capital flows on macroeconomic variables. Third, capital account liberalization is highly related to consumption and investment booms, and subsequent appreciation of nominal and real exchange rates, which leads to the current account worsening. Finally, there is strong evidence of sterilized foreign exchange market intervention in response to capital inflows.
Long-Run Effects of the Korea-China Free-Trade Agreement
This paper uses a 53-country 15-industry computable general equilibrium model of trade to analyze the effects of the Korea-China free trade agreement on the Korean economy, the manufacturing sector in particular. The model is based on Yaylaci and Shikher (2014) which uses the Eaton-Kortum ethodology to explain intra-industry trade. The model predicts that the Korea-China FTA will increase Korea-China manufacturing trade by 56%, manufacturing employment in Korea by 5.7% and China by 0.55%. The model also predicts significant reallocation of employment across industries with the Food industry in Korea losing jobs and other industries there gaining jobs, with the Medical equipment industry gaining the most. There will be some trade diversion from the ASEAN countries, as well as Japan and the United States.
Patience, Persistence and Welfare Costs of Incomplete Markets in Open Economies
In this paper, we investigate the welfare implications of alternative financial market structures in a two-country endowment economy model. In particular, we obtain an analytic expression for the expected lifetime utility of the representative household when sovereign bonds are the only internationally traded asset, and we compare this welfare level with that obtained under complete asset markets. The welfare cost of incomplete markets is negligible if agents are very patient and shocks are not very persistent, but this cost is dramatically larger if agents are relatively impatient and shocks are highly persistent. For realistic cases in which agents are very patient and shocks are highly persistent (that is, the discount factor and the first-order autocorrelation are both near unity), the welfare cost of incomplete markets is highly sensitive to the specific values of these parameters. Finally, using a non-linear solution algorithm, we confirm that a two-country production economy with endogenous labor supply has qualitatively similar welfare properties.
How Much to Share
French Abstract: Combien à partager? Les effets de bien-être des transferts fiscaux. Les récentes crises de la dette souveraine ont interpellé les architectes des politiques publiques et les ont amenés à explorer la possibilité d'établir un système de transferts fiscaux qui atténue l'impact négatif des chocs asymétriques entre pays. À l'aide d'un modèle d'économie simple où la production est fondée sur le travail, on dérive d'abord une solution analytique viable au problème du degré optimal de transferts fiscaux. Dans cette économie, les transferts fiscaux peuvent améliorer le niveau de bien-être en rapprochant l'équilibre concurrentiel avec transferts fiscaux de la s...
International Capital Flows, Boom-Bust Cycles, and Business Cycle Synchronization in the Asia Pacific Region
This article documents evidence of business cycle synchronization in selected Asia Pacific countries since the 1990s. We explain business cycle synchronization by the channel of international capital flows and boom-bust cycles. Using the vector auto-regression 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 also shows that capital flow shocks are positively correlated in the region, which supports the conclusion that capital market liberalization has contributed to business cycle synchronization.
Dynamics of Open Economy Business Cycle Models
This paper examines the dynamic implications of different preference formulations in open economy business cycle models with incomplete asset markets. In particular, we study two preference formulations: a time separable preference formulation with a fixed discount factor, and a time non-separable preference structure with an endogenous discount factor. We analyze the moment implications of two versions of an otherwise identical open economy model -- one with a fixed discount factor and the other with an endogenous discount factor -- and study impulse responses to productivity and world real interest rate shocks. Our results suggest that business cycle implications of the two models are quite similar under conventional parameter values. We also find the approximation errors associated with the solutions of these two models are of the same magnitude.
Spurious Welfare Reversals in International Business Cycle Models
Papers on international business cycles have documented spurious welfare reversals: incomplete markets produce a higher level of welfare than the complete market. This paper first demonstrates how conventional linearization, as used in King, Plosser, and Rebelo (1988), can generate approximation errors that can result in welfare reversals. Using a two-country production economy, we argue that spurious welfare reversals are not only possible but also plausible under reasonable values for model parameters including labor supply elasticity. As a constructive alternative, this paper then proposes an approximation method that modifies the conventional linearization by a bias correction - the linear approximation around a 'stochastic' steady state. We show that this method can be easily implemented and very well approximates the exact solution. The accuracy of the proposed method is by far better than that of the conventional linearization method and as good as that of a perturbation method involving a second-order expansion.
