Supply Capacity, Vertical Specialisation andTrade Costs: The Implications for Aggreagate US Trade Flow Equations

This paper re-examines aggregate and disaggregate import and export demand functions for the United States over the 1975-2010 period. This re-examination is warranted because (1) income elasticities are too high to be warranted by standard theories, and (2) remain high even when it is assumed that supply factors are important. These findings suggest that the standard models omit important factors. An empirical nvestigation ndicates that the rising importance of vertical specialization combined with changing tariff rates and transportation costs explains some of results. Accounting for these factors ields more plausible estimates of income elasticities.imports; exports; elasticities; vertical specialization; production fragmentation; trade costs.

Capital Account Liberalization, Institutions and Financial Development: Cross Country Evidence

The empirical relationship between capital controls and the financial development of credit and equity markets is examined. We extend the literature on this subject along a number of dimensions. Specifically, we (1) investigate a substantially broader set of proxy measures of financial development; (2) create and utilize a new index based on the IMF measures of exchange restrictions that incorporates a measure of the intensity of capital controls; and (3) extend the previous literature by systematically examining the implications of institutional (legal) factors. The results suggest that the rate of financial development, as measured by private credit creation and stock market activity, is linked to the existence of capital controls. However, the strength of this relationship varies with the empirical measure used, and the level of development. These results also suggest that only in an environment characterized by a combination of a higher level of legal and institutional development will the link between financial openness and financial development be readily detectable. A disaggregated analysis indicates that in emerging markets the most important components of these legal factors are the levels of shareholder protection and of accounting standards.

What Matters for Financial Development? Capital Controls, Institutions, and Interactions

We extend our earlier work, focusing on the links between capital account liberalization, legal and institutional development, and financial development, especially that in equity markets. In a panel data analysis encompassing 108 countries and twenty years ranging from 1980 to 2000, we explore several dimensions of the financial sector. First, we test whether financial openness can lead to equity market development when we control for the level of legal and institutional development. Then, we examine whether the opening of the goods sector is a precondition for financial opening. Finally, we investigate whether a well-developed banking sector is a precondition for financial liberalization to lead to equity market development and also whether bank and equity market development complements or substitutes. Our empirical results suggest that a higher level of financial openness contributes to the development of equity markets only if a threshold level of general legal systems and institutions is attained, which is more prevalent among emerging market countries. Among emerging market countries, a higher level of bureaucratic quality and law and order, as well as the lower levels of corruption, increases the effect of financial opening in fostering the development of equity markets. We also find that the finance-related legal/institutional variables do not enhance the effect of capital account opening as strongly as the general legal/institutional variables. In examining the issue of the sequencing, we find that the liberalization in cross-border goods transactions is found to be a precondition for capital account liberalization. Our findings also indicate that the development in the banking sector is a precondition for equity market development, and that the developments in these two types of financial markets have synergistic effects.

Conventional and Unconventional Approaches to Exchange Rate Modeling and Assessment

We examine the relative predictive power of the sticky price monetary model, uncovered interest parity, and a transformation of net exports and net foreign assets. In addition to bringing Gourinchas and Rey’s new approach and more recent data to bear, we implement the Clark and West (forthcoming) procedure for testing the significance of out-of-sample forecasts. The interest rate parity relation holds better at long horizons and the net exports variable does well in predicting exchange rates at short horizons in-sample. In out-of-sample forecasts, we find evidence that our proxy for Gourinchas and Rey’s measure of external imbalances outperforms a random walk at short horizons as do some of other models, although no single model uniformly outperforms the random walk forecast.

Current Account Balances, Financial Development and Institutions: Assaying the World "Savings Glut"

We investigate the medium-term determinants of the current account using a model that controls for factors related to institutional development, with a goal of informing the recent debate over the existence and relevance of the "savings glut." The economic environmental factors that we consider are the degree of financial openness and the extent of legal development. We find that for industrial countries, the government budget balance is an important determinant of the current account balance; the budget balance coefficient is 0.21 in a specification controlling for institutional variables. More interestingly, our empirical findings are not consistent with the argument that the more developed financial markets are, the less saving a country undertakes. We find that this posited relationship is applicable only for countries with highly developed legal systems and open financial markets. For less developed countries and emerging market countries we usually find the reverse correlation; greater financial development leads to higher savings. Furthermore, there is no evidence of "excess domestic saving" in the Asian emerging market countries; rather they seem to have suffered from depressed investment in the wake of the 1997 financial crises. We also find evidence that the more developed equity markets are, the more likely countries are to run current account deficits.

Productivity and the Euro-Dollar Exchange Rate Puzzle

This paper documents the evidence for a productivity based model of the dollar/euro real exchange rate over the 1985-2001 period. We estimate cointegrating relationships between the real exchange rate, productivity, and the real price of oil using the Johansen (1988) and Stock-Watson (1993) procedures. We find that each percentage point in the US-Euro area productivity differential results in a five percentage point real appreciation of the dollar. This finding is robust to the estimation methodology, the variables included in the regression, and the sample period. We conjecture that productivity-based models cannot explain the observed patterns with the standard set of assumptions, and describe a case in which the model can be reconciled with the observed data.

The Determinants of the Global Digital Divide: A Cross-Country Analysis of Computer and Internet Penetration

To identify the determinants of cross-country disparities in personal computer and Internet penetration, we examine a panel of 161 countries over the 1999-2001 period. Our candidate variables include economic variables (income per capita, years of schooling, illiteracy, trade openness), demographic variables (youth and aged dependency ratios, urbanization rate), infrastructure indicators (telephone density, electricity consumption), telecommunications pricing measures, and regulatory quality. With the exception of trade openness and the telecom pricing measures, these variables enter in as statistically significant in most specifications for computer use. A similar pattern holds true for Internet use, except that telephone density and aged dependency matter less. The global digital divide is mainly but by no means entirely accounted for by income differentials. For computers, telephone density and regulatory quality are of second and third importance, while for the Internet, this ordering is reversed. The region-specific explanations for large disparities in computer and Internet penetration are generally very similar. Our results suggest that public investment in human capital, telecommunications infrastructure, and the regulatory infrastructure can mitigate the gap in PC and Internet use.

Three Current Account Balances: A "Semi-Structuralist" Interpretation

Three large current account imbalances -- one deficit (the United States) and two surpluses (Japan and the Euro area) -- are subjected to a minimalist structural interpretation. Though simple, this interpretation enables us to assess how much of each of the imbalances require a real exchange rate adjustment. According to the estimates, a large part of the U.S. current account deficit (nearly 2 percentage points of the 2004 deficit of 5 1/2 percent of GDP) will undergo an adjustment process that involves real depreciation in its exchange rate. For Japan, a little more than 1 percentage point (of GDP) of the current account surplus is found to require an exchange rate movement (real appreciation) as the surpluses adjust down. For the Euro area, less than half a percentage point of its current account surplus is found to require an adjustment via real appreciation.
