Hausmann, R., et al., 2014. Implied Comparative Advantage. CID Working Paper , 276.Abstract

The comparative advantage of a location shapes its industrial structure. Current theoretical models based on this principle do not take a stance on how comparative advantages in different industries or locations are related with each other, or what such patterns of relatedness might imply about the underlying process that governs the evolution of comparative advantage. We build a simple Ricardian-inspired model and show this hidden information on inter-industry and inter-location relatedness can be captured by simple correlations between the observed patterns of industries across locations or locations across industries. Using the information from related industries or related locations, we calculate the implied comparative advantage and show that this measure explains much of the location’s current industrial structure. We give evidence that these patterns are present in a wide variety of contexts, namely the export of goods (internationally) and the employment, payroll and number of establishments across the industries of subnational regions (in the US, Chile and India). The deviations between the observed and implied comparative advantage measures tend to be highly predictive of future industry growth, especially at horizons of a decade or more; this explanatory power holds at both the intensive as well as the extensive margin. These results suggest that a component of the long-term evolution of comparative advantage is already implied in today’s patterns of production.

Kremer, M. & Snyder, C., 2013. When is Prevention More Profitable than Cure? The Impact of Time-Varying Consumer Heterogeneity.Abstract

We argue that in pharmaceutical markets, variation in the arrival time of consumer heterogeneity creates differences between a producer’s ability to extract consumer surplus with preventives and treatments, potentially distorting R&D decisions. If consumers vary only in disease risk, revenue from treatments—sold after the disease is contracted, when disease risk is no longer a source of private information—always exceeds revenue from preventives. The revenue ratio can be arbitrarily high for sufficiently skewed distributions of disease risk. Under some circumstances, heterogeneity in harm from a disease, learned after a disease is contracted, can lead revenue from a treatment to exceed revenue from a preventative. Calibrations suggest that skewness in the U.S. distribution of HIV risk would lead firms to earn only half the revenue from a vaccine as from a drug. Empirical tests are consistent with the predictions of the model that vaccines are less likely to be developed for diseases with substantial disease-risk heterogeneity.

Torres, R.C., 2012. Capital and Labor Mobility and the Size of Sub-national Governments: Evidence from a Panel of Mexican States.Abstract

We examine in this paper the relation between government size and capital and labor openness employing a panel of the 32 Mexican states over the period 1996-2006. Making use of two alternative measures of capital and labor openness and employing several alternative econometric specifications, we first find systematic positive effects of our openness measures on the size of the states’ total government spending. Thereafter, we break down total government expenditure and focus on three subcategories of spending associated with social welfare: education, health and poverty alleviation programs. We find that FDI flows, our proxy for capital openness, are not significant determinants of the state’s social spending, but labor openness, in the form of international migration, has a significant and even greater impact on some of the aforementioned categories than on total spending.

Frankel, J., 2012. The Natural Resource Curse: A Survey of Diagnoses and Some Prescriptions.Abstract

Countries with oil, mineral or other natural resource wealth, on average, have failed to show better economic performance than those without, often because of undesirable side effects. This is the phenomenon known as the Natural Resource Curse. This paper reviews the literature, classified according to six channels of causation that have been proposed. The possible channels are: (i) long-term trends in world prices, (ii) price volatility, (iii) permanent crowding out of manufacturing, (iv) autocratic/oligarchic institutions, (v) anarchic institutions, and (vi) cyclical Dutch Disease. With the exception of the first channel – the long-term trend in commodity prices does not appear to be downward – each of the other channels is an important part of the phenomenon. Skeptics have questioned the Natural Resource Curse, pointing to examples of commodity-exporting countries that have done well and arguing that resource exports and booms are not exogenous. The relevant policy question for a country with natural resources is how to make the best of them.

Frankel, J., 2012. What Small Countries Can Teach the World.Abstract

The large economies have each, in sequence, offered "models" that once seemed attractive to others but that eventually gave way to disillusionment. Small countries may have some answers. They are often better able to experiment with innovative policies and institutions and some of the results are worthy of emulation. This article gives an array of examples. Some of them come from small advanced countries: New Zealand’s Inflation Targeting, Estonia’s flat tax, Switzerland’s debt brake, Ireland’s FDI policy, Canada’s banking structure, Sweden’s Nordic model, and the Netherlands’ labor market reforms. Some examples come from countries that were considered "developing" 40 years ago, but have since industrialized. Korea stands for education; among Singapore’s innovative polices were forced saving and traffic congestion pricing; Costa Rica and Mauritius outperformed their respective regions by, among other policies, foreswearing standing armies; and Mexico experimented successfully with the original Conditional Cash Transfers. A final set of examples come from countries that export mineral and agricultural commodities -- historically vulnerable to the "resource curse" -- but that have learned how to avoid the pitfalls: Chile’s structural budget rules, Mexico’s oil option hedging, and Botswana’s "Pula Fund."

Diagnosing the Binding Constraints on Economic Growth (Belize)
Hausmann, R. & Klinger, B., 2010. Diagnosing the Binding Constraints on Economic Growth (Belize). In Towards a Sustainable and Efficient State: The Development Agenda of Belize. Washington, DC. Washington, DC: Inter-American Development Bank, pp. 11-35. Publisher's VersionAbstract

Belize’s long-term growth performance has been comparatively good. It is not clear what comparator group is relevant, given Belize’s status as both a Caribbean and a Central American country. Compared with its Central American counterparts, Belize has been a growth star. In 1960, it was the second-poorest country in the region; now it is among the “top tier” countries, with gross domestic product (GDP) per capita (Figure 1.1) near that of Costa Rica and Panama. Moreover, much of this growth was achieved after independence. Among its Caribbean peers, however, Belize’s performance has been average, and it has not been able to close the gap with the better-performing economies in the region. And since 2004, economic growth has been sluggish, barely above the rate of population growth, implying that reactivating economic growth is a central development challenge for the country.

Hausmann, R. & Klinger, B., 2008. Growth Diagnostics in Peru.Abstract

This paper presents a growth diagnostic of Peru. It notes that although Peru has recently enjoyed high rates of economic growth, this growth is actually a recovery from a significant and sustained growth collapse that began in the 1970s. The growth collapse was caused by a decline in export earnings due to the fall in international prices and an inadequate investment regime in export activities that led to a fall in market share. This situation led to collateral damage in the form of a balance of payments, fiscal and financial crisis, accompanied by hyperinflation and violence, but these aspects were corrected in the 1990s. However, the transformation of the export sector has been surprisingly small: the same activities that declined – mining and energy – are the ones that are leading the current recovery in exports to levels that in real per capita terms are similar to those achieved 30 years ago. We argue that the lack of structural transformation is associated with Peru’s position in a poorly connected part of the product space and this accentuates coordination failures in the movement to new activities. In addition, Peru’s current export package, is very capital intensive and generates few jobs, especially in urban areas where the bulk of the labor force is now located. This limits the welfare benefits of the current growth path. The key policy message is that the public sector must act to encourage the development of new export activities that better utilize the human resources of the country. This involves action on the macro front to achieve a more competitive real exchange rate, improvements in the capacity to solve coordination failures in the provision of specific public sector inputs and programs to stimulate investment in new tradable activities.

Hausmann, R. & Klinger, B., 2007. Growth Diagnostic: Paraguay.Abstract

Paraguay’s growth history is characterized by prolonged periods of stagnation, interrupted by a few small recessions and growth accelerations. These dynamics reveal that growth in Paraguay has been dependent on latching on to particular export goods enjoying favorable external conditions, rather than driven by macroeconomic or political cycles. Moreover, the country currently has significant room for further export growth in existing products, as well as many new export products that are nearby and have high potential. But these available channels to generate sustained growth have all gone unexploited. Our growth diagnostic indicates that the underlying obstacles that have prevented the country from developing many of the available opportunities are related to two constraints: the provision of infrastructure and a lack of appropriability due to corruption and a poor regulatory environment. The current environment is one where the only activities that can survive have to be un-intensive in infrastructure, and either unintensive in transactions requiring an efficient business environment or at least at a scale where informality and corruption is a viable alternative to institutional blockages. We provide policy recommendations that will help alleviate these problems, focusing on not only on institutional and infrastructure reforms in the abstract, but outlining a process of learning from the relevant private sector actors what sector-specific needs in the areas of regulations and infrastructure are the most important for achieving accelerated growth in Paraguay.

Rodrik, D. & Hausmann, R., 2005. Self-Discovery in a Development Strategy for El Salvador. Economia , 6 (N1).Abstract

El Salvador is a star reformer. After the civil war of the 1980s, the country was able to adopt important political and institutional reforms. These included the incorporation of all political groups into the electoral process, the adoption of a new constitution, the elimination of the military police, the creation of a civilian police with members from both sides of the war, and the adoption of rules to strengthen the independence of the judiciary. On the economic front, the country consolidated its fiscal position, modernized its tax system, liberalized trade and banking, improved the regulation and supervision of its financial system, privatized most state productive assets including energy and telecommunications, and reformed its social security system in line with the Chilean model. It also expanded and granted local autonomy to the school system through the Community-Managed Schools Program (EDUCO). Finally, El Salvador dollarized its financial system in November 2000. Given the investment-grade rating earned by the country, domestic money market rates have converged to U.S. levels.

Unfortunately, El Salvador is not a star performer. Standard theory would predict that such an improvement in the institutional and regulatory environment should be followed by convergence to a higher income level. Instead, after an initial period of recovery that lasted until 1997, real gross national income per capita stagnated at levels comparable to those achieved by the country in the late 1970s. Its income relative to the United States has not recovered from the fall associated with the civil war and is just over half the ratio achieved in the late 1970s.

El Salvador is not alone in finding that reform efforts have had smaller-than-expected
growth effects. With the exception of Chile, the effects of reform ongrowth throughout Latin America have been smaller than the initial estimates carried out in the mid-1990s.In this context, El Salvador is an interesting case, since it has been particularly effective in applying wide-ranging reforms.

This paper explores why these reforms have failed to produce more growth and what can be done about it.2 We begin by placing the economic choices faced by the incoming Salvadoran administration in a regional and historical perspective. The late 1980s and early 1990s in Latin America were preceded by a decade of stagnation, but coincided with a time of unusual confidence in the future. The collapse of communism, the failure of many interventionist policies in Latin America in the 1980s, and Chile’s success gave governments a clear idea of the road they wanted to leave and the road they wanted to take. Inadequate past performance and consensus on the road ahead led to a forceful policy agenda.
