The implications for an open economy of partisan political business cycles: Theory and evidence

This paper develops and tests the predictions of two open economy models in which partisan effects are present, a small-country-one-good model of exchange rate determination and a model that assumes the two countries each specialize in the production of one good. From these models, we can obtain predictions for the behaviour of the terms of trade, the current account, and real and nominal exchange rates. The predictions are tested empirically using panel data from 14 OECD countries and the results provide support for the theoretical predictions that systematic partisan effects are present in current accounts, real exchange rates, and the terms of trade.     

Diversification and tunneling: Evidence from Indian business groups

We provide evidence suggesting an important yet largely unexplored motive for the diversified structure of emerging economy business groups is to facilitate expropriation of minority shareholders by controlling insiders through tunneling. Using firm level panel data from India, and defining the core firm of a group as the one with the largest asset base, we find that the relatedness of the activity of a group affiliate to the activity of the core firm is correlated with the wedge between control and cash flow rights of insiders as well as with the opacity in insider ownership. Firms with ownership-control wedge lower and ownership opacity higher relative to a group’s core firm are more likely to be in activities unrelated to that of the core firm. Our findings are strengthened by evidence of tunneling in the same direction, from affiliates with wedge equal to or higher than that of the core firm to affiliates with wedge lower than that of the core firm. Taken together this suggests an expropriation motive for diversification: affiliate firms are located away from a business group’s core firm to serve as destination points for funds tunneled from the group’s core.     

Sectoral labor adjustment and monetary policy in a small open economy

This paper studies the welfare implications of sectoral labor adjustment cost in a two-sector small open economy model with sticky prices. We find that, when the economy faces external shocks, if monetary policy can stabilize the real economy, then sectoral labor market adjustment cost will lead to welfare loss. However, if monetary policy such as fixed exchange rates cannot stabilize real variables, then some degree of labor market friction will improve welfare instead and the gain will be significant. As a result, the welfare gap between flexible exchange rates and fixed exchange rates decreases with sectoral labor market friction. This is because the friction can offset some of the nominal rigidity and become a substitute for monetary policy to stabilize the real economy.     

Structural changes in exports of an emerging economy: Case of Turkey

This paper indicates that Turkish exports are subject to structural changes as Turkey integrates into global production networks. Integration, which leads vertical specialization in production and changes in the commodity composition of Turkish exports in favor of non-traditional commodities, paces up during economic reform periods. As the export shares of non-traditional commodities, which have higher import and income sensitivity but lower real exchange rate elasticity, increases, coefficients of the aggregate export function change accordingly. Nevertheless, high import and income elasticity of exports imply that the global growth pattern plays a significant role in determining exports of Turkey.     

Foreign direct investment and business cycle co-movements: The panel data evidence

The previous literature has largely overlooked the possible channels through which foreign direct investment (FDI) might influence business cycle synchronization. In this study we analyze the linkages that exist among FDI, trade and industrial dissimilarity in relation to business cycle co-movements using a panel data set taken from 77 pairs of developed countries. The error component three-stage least squares (EC3SLS) estimates from a simultaneous equations model with panel data are shown to be superior to the estimates obtained from single equation models or simultaneous equations models with cross-sectional data. Our results indicate that FDI serves as a channel of international business cycle transmission that is equally important as the channels of trade and monetary policy. On the contrary, industrial dissimilarity is identified as having an indirect impact on the business cycle correlation through trade and FDI. Furthermore, our findings suggest that in our sample FDI is of the horizontal type and tends to substitute for trade.     

Heterogeneity and convergence of regional inflation (prices)

It is generally thought that members in a monetary union experience a similar level of inflation. This paper verifies this conventional belief. Using regional data, we present statistical evidence of heterogeneous inflation in Japan. Not only does the average inflation differ significantly across regions, but regional inflation responds differently to common economic and monetary factors. Furthermore, we show no evidence of price convergence in the entire group of regions although there is some evidence of convergence in subgroups. These results suggest that diversified regional inflation can exist within a monetary union.     

How strong is the global integration of emerging market regions? An empirical assessment

This paper attempts to evaluate the time-varying integration of emerging markets from a regional perspective based on a conditional version of the International Capital Asset Pricing Model (ICAPM) with DCC-GARCH parameters that allows for dynamic changes in the degree of market integration, global market risk premium, regional exchange-rate risk premium, and local market risk premium. Our findings reveal several interesting facts. First, the time-varying degree of integration of four emerging regions under consideration, satisfactorily explained by the regional level of trade openness and the term premium of US interest rates, has recently tended to increase, but these markets still remain substantially segmented from the world market. Second, the local market risk premium is found to explain more than 50% of the total risk premium for emerging market returns. Finally, we show that conditional correlations usually underestimate and overstate the measure of time-varying market integration. The empirical results of this study have some important implications for both global investors and policymakers with respect to dedicated portfolio investments in emerging markets and policy adjustments.     

Bond risk premia, macroeconomic fundamentals and the exchange rate

We propose a two-country no-arbitrage term-structure model to analyze the joint dynamics of bond yields, macroeconomic variables and the exchange rate. The model allows to understand how exogenous shocks to the exchange rate affect the yield curves, how bond yields co-move in different countries and how the exchange rate is influenced by interest rates, macro-economic variables and time-varying bond risk premia.Estimating the model with US and German data, we find that time-varying bond risk premia account for a significant portion of the variability of the exchange rate: apparently, a currency tends to appreciate when investors expect large capital gains on long-term bonds denominated in that currency. A number of other novel empirical findings emerge.     

Capital controls and welfare

This paper computes welfare levels under different degree of capital controls and compares them with the welfare level under perfect capital mobility by using the methodology of Schmitt-Grohé and Uribe (2007). We show that perfect capital mobility is not always optimal and that capital controls may enhance an economy’s welfare level. There exists an optimal degree of capital-account restriction that achieves a higher level of welfare than that under perfect capital mobility, if the economy has costly financial intermediaries. The results of our analysis imply that as the domestic financial intermediaries are less efficient, the government should impose stricter capital controls in the form of a tax on foreign borrowing.     

Application of factor models for the identification of countries sharing international reference-cycles

Using the methodology developed in Stock and Watson (2002a), this paper proposes to exploit the information that contains the factor loading to identify the countries sharing common factors. The proposal is illustrated by analyzing the relation with the international reference-cycle of a large sample of advanced countries from 1950 until 2006.     

Growth, welfare and optimal trade taxes: a fallacy of composition

Optimal export taxation rules out the possibility of immiserizing growth in a two-country world. Thus, productivity increases in the exporting sector must be welfare improving. This paper shows that in a multicountry world such reasoning commits a fallacy of composition. Simultaneous growth of exporting nations can lead to welfare losses in the presence of unilaterally optimal export taxes. Also, optimal export taxes can decline in response to such growth. This result further strengthens the possibility of perverse welfare movements. Thus, standard policy recommendations of increasing productivity in the exporting sector may lead to unintended and self-defeating outcomes.     

Trade agreements and international comovements: The case of NAFTA (North American Free Trade Agreement)

Business cycles correlation between Mexico and the US changed from being on a downward sloping path before 1992 to an upward sloping path after that. This paper suggests that the North American Free Trade Agreement could be the explanation. NAFTA generated not only an increase in the volume of trade but also a change in the elasticity of substitution between imports and exports. The paper tests this hypothesis using the neoclassical business cycles model. Although there are still some discrepancies between the theory and data in the degree of correlation, the direction of change in the model corresponds to the one in the data.     

The trade paradox persists under excise taxes

Brander and Krugman (1983) and Sertel (1988) followed by Krugman (1989), showed two sides of a ‘trade paradox’: The paradox in competition, viz. that opening trade (or increasing competition) may cause welfare to decline, and the paradox in efficiency, viz. that an increase in unit transport cost may increase welfare. In this paper, we consider the situation in an environment where interventionist trade policies are not permitted but each country is sovereign to impose an excise tax (or subsidy). The paradoxes persist under equilibrium excise taxes, reckoned both at the non-cooperative (Nash or dominant strategy) equilibrium and at the cooperative solution among tax-imposing authorities maximizing welfare. We also see that the paradoxes persist in a taxless environment where market equilibrium is Stackelberg rather than Cournot.     

Sovereign default: Which shocks matter?

This paper analyses a small open economy that wants to borrow from abroad, cannot commit to repay debt but faces costs if it decides to default. The model generates analytical expressions for the impact of shocks on the incentive compatible level of debt. Debt reduction generated by severe output shocks is no more than a couple of percentage points. In contrast, shocks to world interest rates can substantially affect the incentive compatible level of debt.     

“Burden sharing” in sovereign debt reduction

We examine a concerted debt reduction deal between a sovereign debtor, a private creditor, and an official creditor, who insures the deposits of the commercial bank. Our results show that a weakening of the financial position of the commercial bank reduces the contribution of the commercial bank and increases that of the official creditor, without affecting the net terms faced by the debtor. This result is robust to changes in seniority. Moreover, leaving both creditor values unchanged requires that commercial banks retire debt at “unfairly” high prices, while official creditors make a net contribution.     

Switching error-correction models of house prices in the United Kingdom

This paper develops error-correction models of real house prices in the UK in which the adjustment coefficient switches stochastically between a stable regime where disequilibrium correction takes place and an unstable regime where such a correction does not occur. The generating mechanism of the shifts is modelled as a Markov process with transition probabilities which are either time-invariant or depend on the extent to which the system is out of disequilibrium. Estimation of error-correction models for the UK reveals that the observed booms in real house prices are associated with an unstable regime. We also find that the probability that the system remains in an unstable regime decreases as deviations from equilibrium increase.     

R&D, risks and overreaction in a market with the absence of the book-to-market effect

Prior studies document that the book-to-market (BM) effect is absent in the Taiwan stock market. Using Taiwanese data covering from 1991 to 2006, we show that, after controlling for the size effect and the Fama and French's (1993) risk factors, the BM effect only exists for those firms with low R&D intensity essentially because these stocks suffer less from investors’ underreaction to R&D investment. The BM effect arises primarily from fundamental reversals acting as a proxy for investors’ overreaction.     

Cross-border rent shifting in international telecommunications

While scholars have questioned the merits of strategic trade policy, such policies have played a major role in international telecommunications. Countries have traditionally linked bilaterally their termination prices for international telephone calls. I show that this linkage can be rationalized as a mutually beneficial constraint on rent seeking. Linkage becomes more challenging to maintain with telecommunications liberalization, competition, and the growth of alternatives for terminating traffic. I consider possible policy approaches to such developments. Overall, this case study suggests that constraining cross-border rent shifting will present a major transitional challenge in international efforts to liberalize services.
