Chekir, H. & Diwan, I., 2015. Crony Capitalism in Egypt. Journal of Globalization and Development.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.

Neighbors and the evolution of the comparative advantage of nations: Evidence of international knowledge diffusion?
Bahar, D., Hausmann, R. & Hidalgo, C., 2014. Neighbors and the evolution of the comparative advantage of nations: Evidence of international knowledge diffusion?. Journal of International Economics , 92 (1). Publisher's VersionAbstract
The literature on knowledge diffusion shows that knowledge decays strongly with distance. In this paper we document that the probability that a product is added to a country's export basket is, on average, 65% larger if a neighboring country is a successful exporter of that same product. For existing products, growth of exports in a country is 1.5% higher per annum if it has a neighbor with comparative advantage in these products. While these results could be driven by a common third factor that escapes our controls, they align with our expectations of the localized character of knowledge diffusion.
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.

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.

Contreras, V., et al., 2014. Expropriation risk and housing prices: Evidence from an emerging market. Journal of Business Research , 67 (5) , pp. 935-942. Publisher's VersionAbstract
This paper examines the microeconomic determinants of residential real estate prices in Caracas, Venezuela, using a private database containing 17,526 transactions from 2008 to 2009. The particular institutional characteristics of many countries in Latin America, and Venezuela in particular, where land invasions and expropriations (with only partial compensation) have been common threats to property owners, provide us with an opportunity to test the effects of these risks on housing prices using a unique database. The effect of these risks on property prices is negative and significant. To our knowledge, this is the first attempt to quantify these impacts in the Hedonic pricing literature applied to real estate. Size, the number of parking spaces, the age of the property, the incidence of crime, and the average income in the neighborhood are significant determinants of prices. Finally, this paper analyzes the microeconomic determinants of housing prices at the municipal level.

Pennacchioli, D., et al., 2014. The retail market as a complex system. EPJ Data Science , 3 (33). Publisher's VersionAbstract

Aim of this paper is to introduce the complex system perspective into retail market analysis. Currently, to understand the retail market means to search for local patterns at the micro level, involving the segmentation, separation and profiling of diverse groups of consumers. In other contexts, however, markets are modelled as complex systems. Such strategy is able to uncover emerging regularities and patterns that make markets more predictable, e.g. enabling to predict how much a country’s GDP will grow. Rather than isolate actors in homogeneous groups, this strategy requires to consider the system as a whole, as the emerging pattern can be detected only as a result of the interaction between its self-organizing parts. This assumption holds also in the retail market: each customer can be seen as an independent unit maximizing its own utility function. As a consequence, the global behaviour of the retail market naturally emerges, enabling a novel description of its properties, complementary to the local pattern approach. Such task demands for a data-driven empirical framework. In this paper, we analyse a unique transaction database, recording the micro-purchases of a million customers observed for several years in the stores of a national supermarket chain. We show the emergence of the fundamental pattern of this complex system, connecting the products’ volumes of sales with the customers’ volumes of purchases. This pattern has a number of applications. We provide three of them. By enabling us to evaluate the sophistication of needs that a customer has and a product satisfies, this pattern has been applied to the task of uncovering the hierarchy of needs of the customers, providing a hint about what is the next product a customer could be interested in buying and predicting in which shop she is likely to go to buy it.

Pritchett, L., et al., 2014. Trillions Gained and Lost: Estimating the Magnitude of Growth Episodes. CID Working Paper , 279.Abstract

We propose and implement a new technique for measuring the total magnitude of a growth episode: the change in output per capita resulting from one structural break in the trend growth of output (acceleration or deceleration) to the next. The magnitude of the gain or loss from a growth episode combines (a) the difference between the post-break growth rate versus a counter-factual "no break" growth rate and (b) the duration of the episode to estimate the difference in output per capita at the end of an episode relative to what it would have been in the "no break" scenario. We use three "counter-factual" growth rates that allow for differing degrees of regression to global average growth: "no change" (zero regression to the mean), "world episode average" (full regression to the mean) and "unconditional predicted growth" (which uses a regression for each growth episode to predict future growth based only on past growth and episode initial level). We can also calculate the net present value at the start of an episode of the gain or loss in output comparing the actual evolution of output per capita versus a counter-factual. This method allows us to place dollar figures on growth episodes. The top 20 growth accelerations have Net Present Value (NPV) magnitude of 30 trillion dollars - twice US GDP. Conversely, the collapse in output in Iran between 1976 and 1988 produced an NPV loss of $143,000 per person. The top 20 growth decelerations account for 35 trillion less in NPV of output. Paraphrasing Lucas, once one begins to think about what determines growth events that cause the appearance or disappearance of output value equal to the total US economy, it is hard to think about anything else.

Coscia, M., Hausmann, R. & Hidalgo, C.A., 2013. The Structure and Dynamics of International Development Assistance. Journal of Globalization and Development , 3 (2) , pp. 1-42. Publisher's VersionAbstract

We study the structure of international aid coordination by creating and analyzing a tripartite network of donor organizations, recipient countries and development issues using web-based information. We develop a measure of coordination and find that it is moderate, achieving about 60% of its theoretical maximum. Many countries are strongly connected to organizations that are related to the issues that are salient there. Nevertheless, we identify many countries that are poorly served, issues that are inadequately attended to, and organizations that focus on the wrong combination of places and issues. Our approach may be used to improve decentralized coordination.

Bustos, S., et al., 2012. The Dynamics of Nestedness Predicts the Evolution of Industrial Ecosystems. PLoS ONE , 7 (11) , pp. 1-8. Publisher's VersionAbstract

In economic systems, the mix of products that countries make or export has been shown to be a strong leading indicator of economic growth. Hence, methods to characterize and predict the structure of the network connecting countries to the products that they export are relevant for understanding the dynamics of economic development. Here we study the presence and absence of industries in international and domestic economies and show that these networks are significantly nested. This means that the less filled rows and columns of these networks' adjacency matrices tend to be subsets of the fuller rows and columns. Moreover, we show that their nestedness remains constant over time and that it 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. We interpret the high level of nestedness observed in these networks in the context of the neutral model of development introduced by Hidalgo and Hausmann (2009). We show that the model can reproduce the high level of nestedness observed in these networks only when we assume a high level of heterogeneity in the distribution of capabilities available in countries and required by products. In the context of the neutral model, this implies that the high level of nestedness observed in these economic networks emerges as a combination of both, the complementarity of inputs and heterogeneity in the number of capabilities available in countries and required by products. The stability of nestedness in industrial ecosystems, and the predictability implied by it, demonstrates the importance of the study of network properties in the evolution of economic networks.

Klimek, P., Hausmann, R. & Thurner, S., 2012. Empirical Confirmation of Creative Destruction from World Trade Data. PLoS ONE , 7 (6). Publisher's VersionAbstract

We show that world trade network datasets contain empirical evidence that the dynamics of innovation in the world economy indeed follows 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.

The network structure of economic output
Hausmann, R. & Hidalgo, C.A., 2011. The network structure of economic output. Journal of Economic Growth. Publisher's VersionAbstract

Much of the analysis of economic growth has focused on the study of aggregate output. Here, we deviate from this tradition and look instead at the structure of output embodied in the network connecting countries to the products that they export. We characterize this network using four structural features: the negative relationship between the diversification of a country and the average ubiquity of its exports, and the non-normal distributions for product ubiquity, country diversification and product co-export. We model the structure of the network by assuming that products require a large number of non-tradable inputs, or capabilities, and that countries differ in the completeness of the set of capabilities they have. We solve the model assuming that the probability that a country has a capability and that a product requires a capability are constant and calibrate it to the data to find that it accounts well for all of the network features except for the heterogeneity in the distribution of country diversification. In the light of the model, this is evidence of a large heterogeneity in the distribution of capabilities across countries. Finally, we show that the model implies that the increase in diversification that is expected from the accumulation of a small number of capabilities is small for countries that have a few of them and large for those with many. This implies that the forces that help drive divergence in product diversity increase with the complexity of the global economy when capabilities travel poorly.

Rodrik, D. & Rosenzweig, M.R., 2010. Development Policy and Development Economics: An Introduction. Handbook of Development Economics , 5 , pp. 4039-5061. Publisher's VersionAbstract

Anyone who undertakes to produce a volume of surveys in economic development must confront the question: Does the world really need another one? The field changes over time and, one hopes, knowledge accumulates. So, one motive is the desire to cover the more recent advances. And indeed, economic development has been one of the most dynamic and innovative fields within economics in recent years. While one primary goal is to inform policy makers, it also hoped that the volume will assist scholars in designing research agendas that are informed by policy questions, in particular, by the gaps in knowledge that would speak to major policy issues. The development field has always been one in which the worlds of research and practice are in close relationship with each other and move in tandem. The large number of PhD economists who work in international organizations such as the World Bank and the influence of academia among developing-country officialdom ensure that ideas emanating from the ivory tower often find quick application. But equally important, in principle, is the reverse feedback—the need to tilt researchers' attention on the questions that are, or should be, on the policy agenda. The organization of the present volume around policy issues is designed to make a contribution toward both of these goals.

Rodrik, D., 2010. Diagnostics before Prescription. Journal of Economic Perspectives , 24 (3) , pp. 33-44.Abstract
Development economists should stop acting as categorical advocates (or detractors) for specific approaches to development. They should instead be diagnosticians, helping decisionmakers choose the right model (and remedy) for their specific realities, among many contending models (and remedies). In this spirit, Ricardo Hausmann, Andres Velasco, and I have developed a "growth diagnostics" framework that sketches a systematic process for identifying binding constraints and prioritizing policy reforms in multilateral agencies and bilateral donors. Growth diagnostics is based on the idea that not all constraints bind equally and that a sensible and practical strategy consists of identifying the most serious constraint(s) at work. The practitioner works with a decision tree to do this. The second step in growth diagnostics is to identify remedies for relaxing the constraint that are appropriate to the context and take cognizance of potential second-best complications. Successful countries are those that have implemented these two steps in an ongoing manner: identify sequentially the most binding constraints and remove them with locally suited remedies. Diagnostics requires pragmatism and eclecticism, in the use of both theory and evidence. It has no room for dogmatism, imported blueprints, or empirical purism.

The Building Blocks of Economic Complexity
Hidalgo, C.A. & Hausmann, R., 2009. The Building Blocks of Economic Complexity. Proceedings of the National Academy of Sciences of the United States of America , 106 (26) , pp. 10570-10575.Abstract

For Adam Smith, wealth was related to the division of labor. As people and firms specialize in different activities, economic effi- ciency increases, suggesting that development is associated with an increase in the number of individual activities and with the complexity that emerges from the interactions between them. Here we develop a view of economic growth and development that gives a central role to the complexity of a country’s economy by interpreting trade data as a bipartite network in which countries are connected to the products they export, and show that it is possible to quantify the complexity of a country’s economy by characterizing the structure of this network. Furthermore, we show that the measures of complexity we derive are correlated with a country’s level of income, and that deviations from this relationship are predictive of future growth. This suggests that countries tend to converge to the level of income dictated by the complexity of their productive structures, indicating that development efforts should focus on generating the conditions that would allow complexity to emerge to generate sustained growth and prosperity.

Hausmann, R., Sturzenegger, F. & Horii, M., 2008. The Growing Current Account Surpluses in East Asia: The Effect of Dark Matter Assets. International Economic Journal , 22 (2) , pp. 141-161. Publisher's VersionAbstract
In a series of papers we have developed the notion that net foreign assets could be better approximated by capitalizing the net investment income line of the balance of payments statistics. Hidden assets or changes in financial costs may change the net return of net foreign assets even when the valuation of assets remains unchanged. By capitalizing the net investment income a more realistic picture emerges on the true burden or return of net foreign assets. This paper estimates external positions for East Asian economies using this methodology and compares the results with that of official accounts. We find that, until the late 1990s, net investment income increased relatively little, signaling that net foreign assets had not grown as suggested by the large current account surpluses of these countries. This is consistent with the fact that the region had attracted large amounts of foreign direct investment, for which the transfer of technology and knowledge are not accurately captured by the valuation of the foreign asset position. Since 2002, however, the trend has reversed, indicating much larger surpluses than officially registered. We discuss individual country cases.
Hausmann, R. & Hidalgo, C.A., 2008. A Network View of Economic Development. Developing Alternatives , 12 (1) , pp. 5-10. Publisher's VersionAbstract
Does the type of product a country exports matter for subsequent economic performance? To take an example from the 19th-century economist David Ricardo, does it matter if Britain specializes in cloth and Portugal in wine for the subsequent development of either country? The seminal texts of development economics held that it does matter, suggesting that industrialization creates externalities that lead to accelerated growth (Rosenstein-Rodan 1943; Hirschman 1958; Matsuyama 1992). Yet, lacking formal models, mainstream economic theory has made little of these ideas. Instead, current dominant theories use two approaches to explain countries’ patterns of specialization.

Hausmann, R. & Sturzenegger, F., 2007. The Valuation of Hidden Assets in Foreign Transactions: Why 'Dark Matter' Matters. Business Economics , 42 (1) , pp. 28-34. Publisher's VersionAbstract
This paper clarifies how the valuation of hidden assets—what we call “dark matter”—changes our assessment of the U.S. external imbalance. Dark matter assets are defined as the capitalized value of the return privilege obtained by U.S. assets. Because this return privilege has been steady over recent decades, it is likely to persist in the future or even to increase, as it becomes leveraged by an increasingly globalized world. Once this is included in future projections of U.S. current accounts, the U.S. external position looks much more balanced than depicted in official statistics.
What You Export Matters
Hausmann, R., Hwang, J. & Rodrik, D., 2007. What You Export Matters. Journal of Economic Growth , 12 (1) , pp. 1-25. Publisher's VersionAbstract
When local cost discovery generates knowledge spillovers, specialization patterns become partly indeterminate and the mix of goods that a country produces may have important implications for economic growth. We demonstrate this proposition formally and adduce some empirical support for it. We construct an index of the “income level of a country’s exports,” document its properties, and show that it predicts subsequent economic growth.
The Product Space Conditions the Development of Nations
Hidalgo, C.A., et al., 2007. The Product Space Conditions the Development of Nations. Science , 317 (5837) , pp. 482-487. Publisher's VersionAbstract
Economies grow by upgrading the products they produce and export. The technology, capital, institutions, and skills needed to make newer products are more easily adapted from some products than from others. Here, we study this network of relatedness between products, or “product space,” finding that more-sophisticated products are located in a densely connected core whereas less-sophisticated products occupy a less-connected periphery. Empirically, countries move through the product space by developing goods close to those they currently produce. Most countries can reach the core only by traversing empirically infrequent distances, which may help explain why poor countries have trouble developing more competitive exports and fail to converge to the income levels of rich countries.
