Foreign Capital and Economic Growth

We document the recent phenomenon of uphill flows of capital from nonindustrial to industrial countries and analyze whether this pattern of capital flows has hurt growth in nonindustrial economies that export capital. Surprisingly, we find that there is a positive correlation between current account balances and growth among nonindustrial countries, implying that a reduced reliance on foreign capital is associated with higher growth. This result is weaker when we use panel data rather than cross-sectional averages over long periods of time, but in no case do we find any evidence that an increase in foreign capital inflows directly boosts growth. What explains these results, which are contrary to the predictions of conventional theoretical models? We provide some evidence that even successful developing countries have limited absorptive capacity for foreign resources, either because their financial markets are underdeveloped, or because their economies are prone to overvaluation caused by rapid capital inflows.

From 'Hindu Growth' to Productivity Surge: The Mystery of the Indian Growth Transition

This paper explores the causes of Indias productivity surge around 1980, more than a decade before serious economic reforms were initiated. Trade liberalization, expansionary demand, a favorable external environment, and improved agricultural performance did not play a role. We find evidence that the trigger may have been an attitudinal shift by the government in the early 1980s that, unlike the reforms of the 1990s, was probusiness rather than promarket in character, favoring the interests of existing businesses rather than new entrants or consumers. A relatively small shift elicited a large productivity response, because India was far away from its incomepossibility frontier. Registered manufacturing, which had been built up in previous decades, played an important role in determining which states took advantage of the changed environment.

Is Newer Better? Penn World Table Revisions and Their Impact on Growth Estimates

This paper sheds light on two problems in the Penn World Table (PWT) GDP estimates. First, we show that these estimates vary substantially across different versions of the PWT despite being derived from very similar underlying data and using almost identical methodologies; that this variability is systematic; and that it is intrinsic to the methodology deployed by the PWT to estimate growth rates. Moreover, this variability matters for the cross-country growth literature. While growth studies that use low-frequency data remain robust to data revisions, studies that use annual data are less robust. Second, the PWT methodology leads to GDP estimates that are not valued at purchasing power parity (PPP) prices. This is surprising because the raison d’etre of the PWT is to adjust national estimates of GDP by valuing output at common international (PPP) prices so that the resulting PPP-adjusted estimates of GDP are comparable across countries. We propose an approach to address these two problems of variability and valuation.

Dynamic Gains from Trade: Evidence from South Africa

This paper examines the empirical relationship between trade and total factor productivity (TFP) in South Africa. Using data on actual trade protection across different manufacturing sectors, it is shown that trade liberalization had a positive impact on TFP growth during the 1990s. In addition, time-series evidence on macro data supports a positive long-run relationship between TFP and openness.

Who Can Explain The Mauritian Miracle: Meade, Romer, Sachs or Rodrik?

This paper examines different explanations--initial conditions, openness to trade and FDI, and institutions--of the Mauritian growth experience since the mid-1970s. We show that arguments based on openness to trade and FDI are either misleading or incomplete, and the transmission mechanism insufficiently identified. However, even when correctly articulated, openness appears to be a proximate rather than an underlying explanation for the Mauritian experience. The institution-based explanation offers greater promise. Ultimately, however, the econometric results indicate that existing explanations may be incomplete. Some idiosyncratic factors, particularly Mauritian diversity and the responses to managing it, may provide the missing pieces in the story of Mauritiuss success.

Currency Undervaluation and Sovereign Wealth Funds: A New Role for the World Trade Organization

Two aspects of global imbalances - undervalued exchange rates and sovereign wealth funds - require a multilateral response. For reasons of inadequate leverage and eroding legitimacy, the International Monetary Fund has not been effective in dealing with undervalued exchange rates. This paper proposes new rules in the World Trade Organization to discipline cases of significant undervaluation that are clearly attributable to government action. The rationale for WTO involvement is that there are large trade consequences of undervalued exchange rates, which act as both import tariffs and export subsidies, and that the WTOs enforcement mechanism is credible and effective. The World Trade Organization would not be involved in exchange rate management, and would not displace the International Monetary Fund. Rather, the authors suggest ways to harness the comparative advantage of the two institutions, with the International Monetary Fund providing the essential technical expertise in the World Trade Organizations enforcement process. There is a bargain to be struck between countries with sovereign wealth funds, which want secure and liberal access for their capital, and capital-importing countries, which have concerns about the objectives and operations of sovereign wealth funds. The World Trade Organization is the natural place to strike this bargain. Its General Agreement on Trade in Services, already covers investments by sovereign wealth funds, and other agreements offer a precedent for designing disciplines for these funds. Placing exchange rates and sovereign wealth funds on the trade negotiating agenda may help revive the Doha Round by rekindling the interest of a wide variety of groups.

The Renminbi Bloc is Here: Asia Down, Rest of the World to Go?

A country’s rise to economic dominance tends to be accompanied by its currency becoming a reference point, with other currencies tracking it implicitly or explicitly. For a sample comprising emerging-market economies, we show that in the last three years, the renminbi (RMB) has increasingly become a reference currency, which we define as one that exhibits a high degree of co-movement with other currencies. In East Asia, there is already a RMB bloc, because the RMB has become the dominant reference currency, eclipsing the US dollar, which is a historic development. In this region, 7 currencies out of 10 co-move more closely with the RMB than with the dollar, with the average value of the co-movement coefficient relative to the RMB being about 60 percent greater than that for the dollar. We find that co-movements with a reference currency, especially for the RMB, are associated with trade integration. We draw some lessons for the prospects for the RMB bloc to move beyond Asia based on a comparison of the RMB’s situation today and that of the Japanese yen in the early 1990s. If trade were the sole driver, a more global RMB bloc could emerge by the mid-2030s, but complementary reforms of the financial and external sectors could considerably expedite the process.

Why India Can Grow at 7 Percent a Year or More: Projections and Reflections

Using a simple growth accounting framework, we project India`s future potential output growth rate through 2025. We argue that there is perhaps more upside potential than downside risks to our central estimate of annual growth, which is close to 7 percent for aggregate output, or 5.5 percent for output per capita.

Africa's Trade Revisted

The popular impression that Africa has not integrated into world trade, as suggested by the evolution in simple indicators, has been called into question recently by more formal analysis. This paper refines and generalizes this analysis, but lends support to the popular view of disintegration. Africa, especially Francophone Africa, is currently under-exploiting its trading opportunities and has witnessed disintegration over time, a trend that is most pronounced in its trade with the technologically advanced countries.

What Determines Long-Run Macroeconomic Stability? Democratic Institutions

We examine the deep determinants of long-run macroeconomic stability in a cross-country framework. We find that conflict, openness, and democratic political institutions have a strong and statistically significant causal impact on macroeconomic stability. Surprisingly the most robust relationship of the three is for democratic institutions. A one standard deviation increase in democracy can reduce nominal instability nearly fourfold. This impact is robust to alternative measures of democracy, samples, covariates, and definitions of conflict. It is particularly noteworthy that a variety of nominal pathologies discussed in the recent macroeconomic literature, such as procyclical policy, original sin, and debt intolerance, have common origins in weak democratic institutions. We also find evidence that democratic institutions both strongly influence monetary policy and have a strong, independent positive effect on stability after controlling for various policy variables.
