Growth Collapses
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.
Finance as the Binding Constraint to Growth
Finance forms a necessary input for production, one so central that it was placed atop the decision tree in the original Growth Diagnostics framework. As we argue, one of the thorniest findings from more than a decade of practice in conducting Growth Diagnostics has been that it is often more difficult to disprove a finance constraint than it is to prove one. Finance has often earned more attention than deserved when considering the many complementary inputs that must be present for production to take place and investments to be profitable. The challenge is in getting the diagnostic right, starting with the use of sound evidence to test for signals.
This paper revisits the starting question of the Growth Diagnostic framework: what does it mean for finance to be a constraint to economic growth? We provide an updated, detailed decision tree for finance, including a rethink of other sources of finance constraints, such as insufficient equity, that were not fully considered in the original decision tree. Our starting point to test for the presence of a finance constraint is to recognize that every financial system suffers from asymmetric information. While information is important for almost all assets in economic transactions, in financial markets, information is the asset. The inherent nature of information asymmetries to financial markets is, in part, what makes finance a focal point for constraint analysis, as greater size and sophistication of financial systems do not make a country immune to finance constraints.
We present three reasons that finance may be constrained: a) insufficient aggregate savings, due to a both inadequate domestic savings and restricted access to foreign borrowing, resulting in not enough loanable funds to finance good projects; b) inadequate institutions and tools for assessing and mitigating risk, that are unable to resolve information asymmetries, preventing markets’ access to savings; and c) problems in financial intermediation, where intermediation itself may be high-risk, monopolistic, or otherwise inefficient to result in insufficient bank lending, or may face borrowers who lack sufficient equity. The paper aims to share lessons learned in testing whether finance is constrained – or not, as well as the policy space to address a finance constraint. The policy discussion emphasizes the risk of misclassifying finance as a constraint when it is not binding on production, as the alternate response of overregulating financial markets can create new intermediation failures to the trust between savers and borrowers. Ultimately, we conclude that policy responses to a finance constraint must be as context specific as the syndrome presented by the diagnosis, where creating functional financial markets lies in preserving the delicate balance of trust between savers and borrowers.

Coordination Failures in Adopting New Technological Capabilities as the Binding Constraint to Growth
The process of structural transformation that has accompanied economic success stories requires an expansion of the technological capabilities held in society. Adding new technological capabilities faces several constraints related to coordination failures, information failures, and the asymmetric nature of technology itself. Although these coordination failures were included in the original Growth Diagnostics framework, practitioners have often found them challenging to analyze. This paper aims to provide a systematic framework and analytic techniques that bring clarity and rigor to the examination of potential constraints in this branch. We posit four different strategic approaches that countries face in the process of structural transformation, centering on two factors: are existing technological capabilities sufficient for growth? And: how easy is it to add the new technological capabilities required to develop new productive sectors? Countries that lack sufficient existing capabilities and must add several capabilities at once in order to enter higher-productivity sectors may be constrained by a capability trap resulting from coordination failures. Even for places where promising opportunities exist, they may be constrained by “low jumpiness” related to information externalities in the process of self-discovery. Diagnostic tests are detailed that can identify the necessary strategic approach. The paper also reflects on the policy space for addressing coordination constraints and outlines the central role of the public sector in enabling coordination of technological capabilities. Both public-private coordination as well as underappreciated elements of public-public coordination in the provision of public goods are addressed.

Buscando virtudes en la lejanía: Recomendaciones de política para promover el crecimiento inclusivo y sostenible en Loreto, Peru
Loreto es un lugar de contrastes. Es el departamento más grande del Perú, pero se encuentra entre los de menor densidad poblacional. Su capital, Iquitos, está más cerca de los estados fronterizos de Brasil y Colombia que de las capitales de sus regiones vecinas en el Perú – San Martín y Ucayali. Sólo se puede llegar a Iquitos por vía aérea o fluvial, lo que la convierte en una de las mayores ciudades del mundo sin acceso por carretera. Desde la fundación del departamento, la economía de Loreto ha dependido de la explotación de recursos naturales, desde el boom del caucho a finales del siglo XIX y principios del XX hasta la extracción petrolera y explotación de recursos forestales que predomina en nuestros días. Este modelo ha traído consigo daños ambientales significativos y ha producido un patrón de crecimiento lento y volátil, que ha abierto una brecha cada vez más amplia entre la economía de la región y la del resto del país. Entre 1980 y 2018, Loreto creció a una tasa promedio compuesta anual cuatro veces menor a la del resto del Perú. Es decir, mientras el resto del Perú triplicó el tamaño de su economía, la de Loreto creció algo menos que un tercio.
En la última década (2008-2018), la región también se ha venido distanciando de sus pares amazónicos en el país (Ucayali, San Martín y Madre de Dios), que han crecido a una tasa promedio anual cinco veces mayor. En este período, el ingreso promedio por habitante en Loreto ha pasado de ser tres cuartas partes del promedio nacional en 2008 a menos de la mitad para 2018. Además del rezago económico – o quizás como consecuencia de él -, Loreto también se ubica entre los departamentos con peores indicadores de desarrollo social, anemia y desnutrición infantil del Perú.
En este contexto, el Laboratorio de Crecimiento de la Universidad de Harvard se asoció con la Fundación Gordon and Betty Moore para desarrollar una investigación que proporcionara insumos y recomendaciones de política para acelerar el desarrollo de la región y generar prosperidad de forma sostenible.
Diagnóstico de Crecimiento de Loreto: Principales Restricciones al Desarrollo Sostenible
Sembrado en el flanco oeste de la selva amazónica, Loreto se encuentra entre los departamentos más pobres y con peores indicadores sociales del Perú. El desarrollo enfrenta allí un sinfín de barreras, pero no todas son igualmente limitantes y tampoco hay recursos para atender todos los problemas a la vez. El Laboratorio de Crecimiento de la Universidad de Harvard, bajo el auspicio de la Fundación Gordon and Betty Moore, ha desarrollado un Diagnóstico de Crecimiento que buscar identificar las restricciones más limitantes, y priorizar las intervenciones de políticas públicas alrededor de un número reducido de factores con el mayor impacto. La investigación, que se fundamenta en análisis de bases de datos nacionales e internacionales, e incluye factores cuantitativos y cualitativos derivados de las visitas de campo, identifica a la conectividad de transporte, los problemas de coordinación asociados al autodescubrimiento, y la energía eléctrica, como las restricciones más vinculantes para el desarrollo de Loreto. De acuerdo con nuestras conclusiones, mejoras en la provisión de estos tres factores tendrían un mayor impacto sobre el desarrollo sostenible de la región que mejores en la educación y los niveles de capital humano, el acceso a financiamiento, y otros sospechosos habituales. Este reporte es el segundo de una investigación más amplia – Transformación estructural y restricciones limitantes a la prosperidad en Loreto, Perú – que busca aportar insumos para el desarrollo de políticas públicas a escala nacional y regional que contribuyan a promover el desarrollo productivo y la prosperidad de la región.

Emerging Cities as Independent Engines of Growth: The Case of Buenos Aires
What does it take for a sub-national unit to become an autonomous engine of growth? This issue is particularly relevant to large cities, as they tend to display larger and more complex know-how agglomerations and may have access to a broader set of policy tools. To approximate an answer to this question, specific to the case of Buenos Aires, Harvard’s Growth Lab engaged in a research project from December 2018 to June 2019, collaborating with the Center for Evidence-based Evaluation of Policies (CEPE) of Universidad Torcuato di Tella, and the Development Unit of the Secretary of Finance of the City of Buenos Aires. Together, we have developed research agenda that seeks to provide inputs for a policy plan aimed at decoupling Buenos Aires’s growth trajectory from the rest of Argentina’s.

Structural Transformation in Chile
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.
Growth Diagnostic: Paraguay
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.
Horrible Trade-offs in a Pandemic: Lockdowns, Transfers, Fiscal Space, and Compliance
In this paper, we develop a heterogeneous agent general equilibrium framework to analyze optimal joint policies of a lockdown and transfer payments in times of a pandemic. In our model, the effectiveness of a lockdown in mitigating the pandemic depends on endogenous compliance. A more stringent lockdown deepens the recession which implies that poorer parts of society find it harder to subsist. This reduces their compliance with the lockdown, and may cause deprivation of the very poor, giving rise to an excruciating trade-off between saving lives from the pandemic and from deprivation. Lump-sum transfers help mitigate this trade-off. We identify and discuss key trade-offs involved and provide comparative statics for optimal policy. We show that, ceteris paribus, the optimal lockdown is stricter for more severe pandemics and in richer countries. We then consider a government borrowing constraint and show that limited fiscal space lowers the optimal lockdown and welfare, and increases the aggregate death burden during the pandemic. We finally discuss distributional consequences and the political economy of fighting a pandemic.
