Levy, D., et al., 2015. ¿Por Que Chiapas Es Pobre?.Abstract

Chiapas es, comoquiera que se le mire, el estado más atrasado de México. Su ingreso por habitante es el más bajo de las 32 entidades federativas, apenas 40% de la media nacional. Su tasa de crecimiento durante la década 2003-2013 también fue la más baja (0,2%), por lo que la brecha que lo separa del promedio nacional creció de 53% a 60%. Eso quiere decir que hoy en día el ingreso promedio de una entidad federal en México está dos veces y media por encima de Chiapas. Los dos estados que le siguen, Oaxaca y Guerrero, están 25% y 30% por encima de Chiapas2. De acuerdo con el Instituto Nacional de Estadística y Geografía de México (INEGI), Chiapas es también el estado de mayor pobreza (74,7%) y pobreza extrema (46,7%).

Hausmann, R. & Chauvin, J., 2015. Moving to the Adjacent Possible: Discovering Paths for Export Diversification in Rwanda.Abstract

How can Rwanda, which currently has one of the lowest levels of income and exports per capita in the world, grow and diversify its economy in presence of significant constraints? We analyze Rwanda's historical growth and trade performance and find that Rwanda's high transportation costs and limited productive knowledge have held back greater export development and have resulted in excessive rural density. Three basic commodities – coffee, tea, and tin – made up more than 80 percent of the country's exports through its history and still drive the bulk of export growth today. Given Rwanda’s high population density and associated land scarcity, these traditional exports cannot create enough jobs for its growing population, or sustainably drive future growth. Rwanda needs new, scalable activities in urban areas. In this report, we identify a strategy for greater diversification of exports in Rwanda that circumvents the key constraints and is separately tailored for regional and global export destinations. Our results identify more than 100 tradable products that lie at Rwanda's knowledge frontier, are not intensive in Rwanda's scarce resources, and economize on transportation costs. Our analysis produces a vision of a more diversified Rwanda, which can be used as a guide for investment promotion decisions. We illustrate an approach that can be applied to other settings in order to identify opportunities for export diversification that take seriously local constraints and external market opportunities.

Reinhart, C. & Santos, M.A., 2015. From Financial Repression to External Distress: The Case of Venezuela.Abstract

Recent work has supported that there is a connection between domestic debt level and sovereign default on external debt. We examine the potential linkages in a case study of Venezuela from 1984 to 2013. This unique example encompasses multiple financial crises, cycles of liberalization and policy reversals, and alternative exchange rate arrangements. The Venezuelan experience reveals a nexus among domestic debt, financial repression, and external vulnerability. Unlike foreign currency-denominated debt, debt in domestic currency may be reduced through financial repression, a tax on bondholders and savers producing negative real interest rates. Using a variety of methodologies we estimate the magnitude of the tax from financial repression. On average, this financial repression tax (as a share of GDP) is similar to those of OECD economies, in spite of much higher domestic debt-to-GDP ratios in the latter. The financial repression "tax rate" is significantly higher in years of exchange controls and legislated interest rate ceilings. In line with earlier literature on capital controls, our comprehensive measures of capital flight document a link between domestic disequilibrium and a weakening of the net foreign asset position via private capital flight. We suggest these findings are not unique to the Venezuelan case.

Hausmann, R., Ganguli, I. & Viarengo, M., 2014. Marriage, Education, and Assortative Mating in Latin America. Applied Economic Letters , 21 (12) , pp. 806-811. Publisher's VersionAbstract
In this article, we establish facts related to marriage and education in Latin American countries. Using census data from IPUMS International, we show how marriage and assortative mating patterns have changed from 1980 to 2000 and how the patterns in Latin America compare to the United States. We find that in Latin American countries, highly educated individuals are less likely to be married than the less educated, and the pattern is stronger for women. We also show that while it has been increasing over time, there is less positive assortative mating in Latin America than in the United States.

Hausmann, R., Ganguli, I. & Viarengo, M., 2014. Closing the gender gap in education: What is the state of gaps in labour force participation for women, wives and mothers?. International Labor Review , 153 (2) , pp. 173-207. Publisher's VersionAbstract

The educational gender gap has closed or reversed in many countries. But what of gendered labour market inequalities? Using micro‐level census data for some 40 countries, the authors examine the labour force participation gap between men and women, the “marriage gap” between married and single women's participation, and the “motherhood gap” between mothers' and non‐mothers' participation. They find significant heterogeneity among countries in terms of the size of these gaps, the speed at which they are changing, and the relationships between them and the educational gap. But counterfactual regression analysis shows that the labour force participation gap remains largely unexplained by the other gaps.

Hausmann, R., et al., 2014. How should Uganda grow?.Abstract

Income per capita in Uganda has doubled in the last 20 years. This remarkable performance has been buoyed by significant aid flows and large external imbalances. Economic growth has been concentrated in non-tradable activities leading to growing external imbalances and a growing gap between rural and urban incomes. Future growth will depend on achieving sufficient export dynamism. In addition, growth faces a number of other challenges: low urbanization rate, rapid rural population growth and high dependency ratios. However, both the dependency ratio and fertility rates have begun to decline recently. Rural areas are also severely overcrowded with low-productivity subsistence agriculture as a pervasive form of production. Commercial agriculture has great possibilities to increase output, but as the sector improves its access to capital, inputs and technology it will shed jobs rather than create them.

These challenges combined tell us that future growth in Uganda will require a rapid rate of export growth and economic diversification. The country faces the prospect of an oil boom of uncertain size and timing. It could represent an important stepping stone to achieve external sustainability, expanded income and infrastructure and a greater internal market. However, as with all oil booms, the challenges include avoiding the Dutch disease, managing the inevitable volatility in oil incomes and avoiding inefficient specialization in oil. Policies that set targets for the non-oil deficit could help manage some of these effects, but a conscious strategy to diversify would still be needed.

The best strategy is therefore to use the additional oil revenue and accompanying investments to promote a diversification strategy that is sustainable. To determine how to encourage such a transformation, we draw on a new line of research that demonstrates how development seldom implies producing more of the same. Instead, as countries grow, they tend to move into new industries, while they also increase productivity in existing sectors. In this report, we analyze what those new industries might be for Uganda.

To do so, we first look to those products which balance the desire to increase the diversification and complexity of production, while not over-stretching existing capabilities. These include mostly agricultural inputs, such as agrochemicals and food processing. In addition, Uganda should concurrently develop more complex industries, such as construction materials, that are reasonably within reach of current capabilities and will be in great demand in the context of an oil boom. Here, the fact that Uganda is landlocked and faces high import costs will provide natural protection to the expanding demand in Uganda and neighboring countries. We conclude with a discussion of the government policies that will support Uganda in developing new tradable industries.

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.

Hausmann, R., Dell’Erba, S. & Panizza, U., 2013. Debt Levels, Debt Composition, and Sovereign Spreads in Emerging and Advanced Economies.Abstract

This paper studies the relationship between sovereign spreads and the interaction between debt composition and debt levels in advanced and emerging market countries. It finds that in emerging market countries there is a significant correlation between spreads and debt levels. This correlation, however, is not statistically significant in countries where most public debt is denominated in local currency. In advanced economies, the magnitude of the correlation between debt levels and spreads is about one fifth of the corresponding correlation for emerging market economies. In Eurozone countries, however, the correlation between spreads and debt ratios is similar to that of emerging market countries. The paper also shows that the financial crisis amplified the relationship between spreads and debt levels within the Eurozone but had no effect on the relationship between spreads and debt in standalone countries. Finally, the paper shows that the relationship between debt levels and spreads is amplified by the presence of large net foreign liabilities. This amplifying effect of net foreign liabilities is larger in the Eurozone than in standalone advanced economies. The paper concludes that debt composition matters and corroborates the original sin hypothesis that, rather than being a mere reflection of institutional weaknesses, the presence of foreign currency debt increases financial fragility and leads to suboptimal macroeconomic policies.

Diwan, I., Gaddah, O. & Osire, R., 2013. Looking like an Industry: Supporting Commercial Agriculture in Africa.Abstract

It has long been known that countries only converge conditionally i.e. poor countries catch up with richer ones only if they adopt policies and institutions that are conducive to economic growth. Recently, Dani Rodrik (2011) has shown that manufacturing industries, unlike countries, converge unconditionally. We look at countries' performance in agriculture and find that agricultural productivity actually shows unconditional divergence (and like GDP, conditional converge). This means that agriculture very much behaves like a country and not like industry. We find however that many crops do converge unconditionally, like industry. The question we then ask is: how can we make particular sectors in agriculture more like an "industry" and less like a "country?" The paper argues that the solution lies in finding business models that provide capital and access to missing markets in an aggregated fashion, thus forming high-productivity islands of quality. We provide examples and a discussion of promising business models that do that.

Pritchett, L. & Kenny, C., 2013. Promoting Millennium Development Ideals: The Risks of Defining Development Down.Abstract

The approach of 2015, the target date of the Millennium Development Goals, sets the stage for a global reengagement on the question of "what is development?" We argue that the post-2015 development framework for development should include Millennium Development Ideals which put into measurable form the high aspirations countries have for the well-being of their citizens. Standing alone, low bar targets like the existing Millennium Development Goals "define development down" and put at risk both domestic and global coalitions to support to an inclusive development agenda. Measuring development progress exclusively by low bar targets creates the illusion that specific targeted programs can be an adequate substitute for a broad national and global development agenda.

Pritchett, L. & Viarengo, M., 2013. The State, Socialization, and Private Schooling: When Will Governments Support Alternative Producers?.Abstract

Understanding the institutional features that can improve learning outcomes and reduce inequality is a top priority for international and development organizations around the world. Economists appear to have a good case for support to non-governmental alternatives as suppliers of schooling. However, unlike other policy domains, freer international trade or privatization, economists have been remarkably unsuccessful in promoting the adoption of this idea. We develop a simple general positive model of why governments typically produce schooling which introduces the key notion of the lack of verifiability of socialization and instruction of beliefs, which makes third party contracting for socialization problematic. We use the model to explain variations around the world in levels of private schooling. We also predict the circumstances in which efforts to promote the different alternatives to government production – like charter, voucher, and scholarship - are likely to be successful.

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.

Diwan, I., 2013. Who are the Democrats? Leading Opinions in the Wake of Egypt's 2011 Popular Uprisings.Abstract

I look at changes in public opinion in Egypt, using the two waves of 2000 and 2008 of the World Value Survey. I find that during this period, there has been a major increase in popular support for democracy, a sizable rise in concerns about inequality, and a fall in support for political Islam. I examine the extent to which these changes are connected, and how they clustered along class, age, and education lines. The main findings are that while in 2000, younger Egyptians were more progressive than their parents, by 2008, Egyptian society had become much more organized around class interests and showed little inter-generational differentiation. New democrats come from all backgrounds, but with a concentration among those on the left. Among social classes, the middle class emerges as the main champion for democracy, driven by both aspiration and grievances motives

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.

Peters, P., 2012. Conflicts Over Land and Threats to Customary Tenure in Africa Today.Abstract

Issues swirling around land across Africa have never been so central to key social and political-economic dynamics as they are at the present time. The first part of the paper briefly reviews the construction of customary tenure and the historical phases of administrative interventions into land tenure, and considers their heritage in contemporary situations. The second part reviews the increasing competition and conflict centered on land; the increase in various types of land transfers that are implicated in the pervasive social conflict focused on land; and the associated rise in social inequality and contestation over belonging and citizenship. The third and final part discusses ‘land grabs’, the most recent surge of international interest in African land, and external and internal threats to ‘customary’ rights in land. The overall conclusion is that while relations around land have long been central to political economy, culture and society across the continent, their greater salience in intensifying struggles among actors within and from outside Africa has significance for the disposition of authority, property and citizenship.

Chekir, H. & Diwan, I., 2012. Crony Capitalism in Egypt.Abstract

The paper studies the nature and extent of Egyptian "crony" capitalism by comparing the corporate performance and the stock market valuation of politically connected and unconnected firms, before and after the 2011 popular uprising that led to the end of President Mubarak 30 years rule. First, we identify politically connected firms and conduct an event study around the events of 2011, as well as around previous events related to rumors about Mubarak’s health. We estimate the market valuation of political connections to be 20% to 23% of the value of connected firms. Second, we explore the mechanisms used for granting these privileges by looking at corporate behavior before 2011. It appears that these advantages allowed connected firms to increase their market size and power and their borrowings. We finally compare the performance of firms and find that the rate of return on assets of connected firms was lower than that of non-connected firms by nearly 3 percentage points. We argue that this indicates that the granting of privileges was not part of a successful industrial policy but instead, that it led to a large misallocation of capital towards less efficient firms, which together with reduced competition, led to lower economic growth.

Bustos, S., et al., 2012. The Dynamics of Nestedness Predicts the Evolution of Industrial Ecosystems.Abstract

Decades of research in ecology have shown that nestedness is a ubiquitous characteristic of both, biological and economic ecosystems. The dynamics of nestedness, however, have rarely been observed. Here we show that the nestedness of both, the network connecting countries to the products that they export and the network connecting municipalities to the industries that are present in them, remains constant over time. Moreover, we find that the conservation of nestedness is sustained by both, a bias for industries that deviate from the networks' nestedness to disappear, and a bias for the industries that are missing according to nestedness to appear. This makes the appearance and disappearance of individual industries in each location predictable. The conservation of nestedness in industrial ecosystems, and the predictability implied by it, demonstrates the importance of industrial ecosystems in the long term survival of economic activities.

Ashraf, Q.H., Weil, D.N. & Wilde, J., 2012. The Effect of Fertility Reduction on Economic Growth.Abstract

We assess quantitatively the effect of exogenous reductions in fertility on output per capita. Our simulation model allows for effects that run through schooling, the size and age structure of the population, capital accumulation, parental time input into child-rearing, and crowding of fixed natural resources. The model is parameterized using a combination of microeconomic estimates, data on demographics and natural resource income in developing countries, and standard components of quantitative macroeconomic theory. We apply the model to examine the effect of a change in fertility from the UN medium-variant to the UN low-variant projection, using Nigerian vital rates as a baseline. For a base case set of parameters, we find that such a change would raise output per capita by 5.6 percent at a horizon of 20 years, and by 11.9 percent at a horizon of 50 years.

Klimek, P., Hausmann, R. & Thurner, S., 2012. Empirical Confirmation of Creative Destruction from World Trade Data.Abstract

We show that world trade network datasets contain empirical evidence that the dynamics of innovation in the world economy follows indeed the concept of creative destruction, as proposed by J.A. Schumpeter more than half a century ago. National economies can be viewed as complex, evolving systems, driven by a stream of appearance and disappearance of goods and services. Products appear in bursts of creative cascades. We find that products systematically tend to co-appear, and that product appearances lead to massive disappearance events of existing products in the following years. The opposite – disappearances followed by periods of appearances – is not observed. This is an empirical validation of the dominance of cascading competitive replacement events on the scale of national economies, i.e. creative destruction. We find a tendency that more complex products drive out less complex ones, i.e. progress has a direction. Finally we show that the growth trajectory of a country’s product output diversity can be understood by a recently proposed evolutionary model of Schumpeterian economic dynamics.
