For Adam Smith, wealth was related to the division of labor. As people and firms specialize in different activities, economic efficiency 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 in order to generate sustained growth and prosperity.
Hausmann, R., Rodrik, D. & Velasco, A., 2008. Growth Diagnostics. In The Washington Consensus Reconsidered: Towards a New Global Governance. Oxford University Press, pp. 324-355.Abstract
Most well-trained economists would agree that the standard policy reforms included in the Washington Consensus have the potential to be growth promoting. What the experience of the last 15 years has shown, however, is that the impact of these reforms is heavily dependent on circumstances. Policies that work wonders in some places may have weak, unintended, or negative effects in others.1 We argue in this chapter that this calls for an approach to reform that is much more contingent on the economic environment, but one that also avoids an ‘anything goes’ attitude of nihilism. We show it is possible to develop a unified framework for analyzing and formulating growth strategies that is both operational and based on solid economic reasoning. The key step is to develop a better understanding of how the binding constraints on economic activity differ from setting to setting. This understanding can then be used to derive policy priorities accordingly, in a way that uses efficiently the scarce political capital of reformers.
This paper systematizes the implementation of the Growth Diagnostics framework. It aims to give the meta-steps that a persuasive growth diagnosis should have, and elaborates on the strategies and methods that may be used. Rather than a step-by-step instruction manual or handbook, this paper is meant to be a ‘mindbook’, suggesting how to think about the problem of identifying a country’s constraints to growth.
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.
Much of development policy has been based on the search for a short to do list that would get countries moving. In this paper I argue that economic activity requires a large and highly interacting set of public policies and services, which constitute inputs into the production process. This is reflected in the presence, in all countries, of hundreds of thousands of pages of legislation and hundreds of public agencies. Finding out what is the right mix of the public inputs, and more importantly, what is a valuable change from the current provision is as complex as determining what is the right mix of private provision of goods. In the latter case, economists agree that this process cannot be achieved through central planning and that the invisible hand of the market is the right approach, because it allows decisions to be made in a more decentralized manner with more information. I argue that a similar solution is required to deal with the complexity of the public policy mix.
This paper establishes a robust stylized fact: changes in the revealed comparative advantage of nations are governed by the pattern of relatedness of products at the global level. As countries change their export mix, there is a strong tendency to move towards related goods rather than to goods that are farther away. The pattern of relatedness of products is only very partially explained by similarity in broad factor or technological intensities, suggesting that the relevant determinants are much more product-specific. Moreover, the pattern of relatedness of products exhibits very strong heterogeneity: there are parts of this ‘product space’ that are dense while others are sparse. This implies that countries that are specialized in a dense part of the product space have an easier time at changing their revealed comparative advantage than countries that are specialized in more disconnected products.
This book identifies the binding constraints to growth of Morocco. It applies an innovative procedure known as 'growth diagnostic' and has a central finding. The Moroccan economy suffers from a too slow process of structural transformation for achieving higher growth, especially for its exports that face unfavorable external shocks arising from competitor countries in the main markets for Moroccan exports. This process of so-called 'productive diversification' requires that Morocco enhance its competitiveness. Four government failures are identified as the binding constraints to growth in Morocco: a rigid labor market; a taxation regime that represents a heavy burden for firms and an obstacle to hiring skilled human capital; a fixed exchange rate regime that has allowed regaining price stability, but, given existing rigidites in the labor market, does not favor international competitiveness; and an anti-export bias, featuring a still high level of trade protectionism despite recent progress in tariff reductions and the signing of several Free Trade Agreements. In parallel, three market failures affect competitiveness and innovation: information failures, coordination failures between the public and private sector, and training failures that rank the country among those with the lowest level of training offered by businesses.
In this paper we examine the product space and its consequences for the process of structural transformation. We argue that the assets and capabilities needed to produce one good are imperfect substitutes for those needed to produce other goods, but the degree of asset specificity varies widely. Given this, the speed of structural transformation will depend on the density of the product space near the area where each country has developed its comparative advantage. While this space is traditionally assumed to be smooth and continuous, we find that in fact it is very heterogeneous, with some areas being very dense and others quite sparse. We develop a measure of revealed proximity between products using comparative advantage in order to map this space, and then show that its heterogeneity is not without consequence. The speed at which countries can transform their productive structure and upgrade their exports depends on having a path to nearby goods that are increasingly of higher value.
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-thanexpected 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.
