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.

The main purpose of industrial policy is to speed up the process of structural change towards higher productivity activities. This paper builds on our earlier writings to present an overall design for the conduct of industrial policy in a low- to middle-income country. It is stimulated by the specific problems faced by South Africa and by our discussions with business and government officials in that country. We present specific recommendations for the South African government in the penultimate section of the paper.

Beneficiation, moving downstream, and promoting greater value added in natural resources are very common policy initiatives to stimulate new export sectors in developing countries, largely based on the premise that this is a natural and logical path for structural transformation. But upon closer examination, we find that very few countries that export raw materials also export their processed forms, or transition to greater processing. The quantitative analysis finds that broad factor intensities do a much better job of identifying patterns of production and structural transformation than forward linkages, which have an insignificant impact despite the fact that our data is biased against finding significant effects of factor intensities and towards finding significant effects of forward linkages. Moreover, the explanatory power of forward linkages is even smaller in sectors with high transport costs, and in sectors classified as primary products or raw materials, which are the most common targets of such policies. Finally, the results are the same even when only considering developed countries, meaning that colonial legacy inhibiting transitions to natural resource processing are not to blame. These results suggest that policies to promote greater downstream processing as an export promotion policy are misguided. Structural transformation favors sectors with similar technological requirements, factor intensities, and other requisite capabilities, not products connected in production chains. There is no reason for countries like South Africa to focus attention on beneficiation at the expense of policies that would allow other export sectors to emerge. This makes no sense conceptually, and is completely inconsistent with international experience. Quite simply, beneficiation is a bad policy paradigm.

The purpose of this paper is to analyze Colombia’s experiences with and opportunities for export led growth. We first review Colombia’s growth and export performance over the past 30 years and find that the country is indeed facing an export challenge. We then go on to develop new metrics and apply them to Colombia’s export challenge. First, we consider the opportunities for upgrading quality within existing exports, and find that Colombia has very little opportunity for growth in this dimension. Second, we consider the level of sophistication of the current export basket, and find that it is low and commensurate with the lack of export dynamism. Although not a significant drag on growth, the current export basket will not be sufficient to fuel future output growth. Finally, we develop the concept distances between products, open forest, and the option value of exports to examine the possibility that Colombia’s current structure of production is itself a barrier to future structural transformation. While improvements in the export package have been slow in the past, this evidence suggests that Colombia does now enjoy more options for future structural transformation. As there are attractive options for structural transformation nearby, a parsimonious approach to industrial strategy, rather than a risky strategic bet to move to a new part of the product space, seems appropriate. In order to inform such a strategy, we use the metrics developed in the diagnostic to evaluate new export activities in terms of their proximity to current activities, their sophistication, and their strategic value. We identify the sectors representing the best tradeoffs between these aims for Colombia as a whole, as well as its regions. We also devote separate attention to the topic of Agricultural exports, and to exports of services. Finally, we use these metrics to analyze the list of ‘high-potential’ sectors in the United States, developed by another firm, as well as the sectors prioritized in Colombia’s Agenda Interna. These external lists of high-potential sectors are found to be sensible, but could be further rationalized using these metrics. This identification of nearby, high-potential, and strategically valuable sectors is not meant to be a definitive list for targeted subsidies and ‘picking winners’. Rather, it provides a robust data-driven approach to inform the next steps in achieving export-led growth in Colombia: which private sector actors should be consulted first? What sector-specific reforms should be stressed? How should public spending on infrastructure and training, which are also sector-specific, be prioritized? What foreign firms should be targeted by FDI promotion agencies? These decisions can be informed by our analysis and the accompanying data.

The main finding of this analysis is that Chile’s pattern of specialization implies little opportunities for easy movements to new activities. Chile is specialized in an extremely sparse part of the product space and has a relatively unsophisticated export package. Past growth has been surprisingly strong given this pattern of specialization, as has been performance in the services sector, and it appears that there does remain some room to continue growing through quality upgrading in existing products. However, Chile has little room to increase its market share in existing products, and its current export package does not offer a path to future structural transformation and growth. Furthermore, this isn’t due to Chile’s status as a natural resource-based economy, as the country lags in these dimensions even when compared to countries like Canada, Australia, and New Zealand. Movements to new sectors are necessary, but will be difficult given this pattern of specialization. This suggests that there should be some scope for public investment in the study and coordination of new export activities to fuel long-term economic growth.

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.

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 paper clarifies how dark matter changes our assessment of the US external imbalance. Dark matter assets are defined as the capitalized value of the return privilege obtained by US 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 US current accounts, the US external position looks much more balanced than depicted in official statistics.

We study episodes where economic growth decelerates to negative rates. While the majority of these episodes are of short duration, a substantial fraction last for a longer period of time than can be explained as the result of business-cycle dynamics. The duration, depth and associated output loss of these episodes differs dramatically across regions. We investigate the factors associated with the entry of countries into these episodes as well as their duration. We find that while countries fall into crises for multiple reasons, including wars, export collapses, sudden stops and political transitions, most of these variables do not help predict the duration of crises episodes. In contrast, we find that a measure of the density of a country's export product space is significantly associated with lower crisis duration. We also find that unconditional and conditional hazard rates are decreasing in time, a fact that is consistent with either strong shocks to fundamentals or with models of poverty traps.

China’s economic and social achievements since the beginning of reform and opening are unprecedented in global history. Managing the growth process in this continuously changing environment has required great skill and the use of unconventional economic policy. Now China has entered a new era in its development process with a set of challenges largely different from those of the recent past. Some problems - such as growing internal and external structural imbalances, increasing income and regional inequality – have arisen from, or been exacerbated by, the very pattern and success of high growth since reforms began. Others are newly posed by rapid changes in the global economy. These challenges can best be tackled in an integrated and coordinated fashion. This report, supported by the China Economic Research and Advisory Programme (CERAP), identifies the primary challenges facing China today and presents options for meeting them.

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.

This paper explores export performance in South Africa over the past 50 years, and concludes that a lagging process of structural transformation is part of the explanation for stagnant exports per capita. Slow structural transformation in South Africa is found to be a consequence of the peripheral nature of South Africa’s productive capabilities. We apply new tools to evaluate South Africa’s future prospects for structural transformation, as well as to explore the sectoral priorities of the DTI’s draft industrial strategy. We then discuss policy conclusions, advocating an ‘open-architecture’ industrial policy where the methods applied herein are but one tool to screen private sector requests for sector-specific coordination and public goods.

India’s fiscal problem has deep roots in its federal fiscal system, where multiple players find it difficult to coordinate adjustment. The size and closed nature of the Indian economy, aided by its deep domestic capital market and large captive pool of domestic savings, has disguised the cost of fiscal laxity and complicated the building of a consensus on reform. The new fiscal responsibility act establishes a new rules-based system to overcome this coordination failure. To strengthen the framework, we recommend an autonomous scorekeeper and the extension of similar rules to the state governments as part of a comprehensive reform of the federal system.

In the presence of uncertainty about what a country can be good at producing, there can be great social value to discovering costs of domestic activities because such discoveries can be easily imitated. We develop a general-equilibrium framework for a small open economy to clarify the analytical and normative issues. We highlight two failures of the laissez-faire outcome: there is too little investment and entrepreneurship ex ante, and too much production diversification ex post. Optimal policy consists of counteracting these distortions: to encourage investments in the modern sector ex ante, but to rationalize production ex post. We provide some informal evidence on the building blocks of our model.
