Diodato, D., Hausmann, R. & Schetter, U., 2022. A Simple Theory of Economic Development at the Extensive Industry Margin.Abstract
We revisit the well-known fact that richer countries tend to produce a larger variety of goods and analyze economic development through (export) diversifcation. We show that countries are more likely to enter ‘nearby’ industries, i.e., industries that require fewer new occupations. To rationalize this finding, we develop a small open economy (SOE) model of economic development at the extensive industry margin. In our model, industries differ in their input requirements of non-tradeable occupations or tasks. The SOE grows if profit maximizing frms decide to enter new, more advanced industries, which requires training workers in all occupations that are new to the economy. As a consequence, the SOE is more likely to enter nearby industries in line with our motivating fact. We provide indirect evidence in support of our main mechanism and then discuss implications: We show that there may be multiple equilibria along the development path, with some equilibria leading on a pathway to prosperity while others resulting in an income trap, and discuss implications for industrial policy. We finally show that the rise of China has a non-monotonic effect on the growth prospects of other developing countries, and provide suggestive evidence for this theoretical prediction.

Hausmann, R., et al., 2022. Cutting Putin’s Energy Rent: ‘Smart Sanctioning’ Russian Oil and Gas.Abstract

Following the Russian aggression against Ukraine, major sanctions have been imposed by Western countries, most notably with the aim of limiting Russia’s access to hard international currency. However, Russia remains the world’s first exporter of oil and gas, and at current energy prices this provides large hard currency revenues. As the war continues, European governments are under increased pressure to scale-up their energy sanctions, following measures taken by the United States, the United Kingdom, Canada and Australia. This piece argues that given the inelasticity of Russia’s oil and gas supply, for Europe the most efficient way to sanction Russian energy would not be an embargo, but the introduction of an import tariff that can be used flexibly to control the degree of economic pressure on Russia.

O'Brien, T., et al., 2022. What Will It Take for Jordan to Grow?.Abstract
This report aims to answer the critical but difficult question: "What will it take for Jordan to grow?" Though Jordan has numerous active growth and reform strategies in place, they do not clearly answer this fundamental question. The Jordanian economy has experienced more than a decade of slow growth. Per capita income today is lower than it was prior to the Global Financial Crisis as Jordan has experienced a refugee-driven population increase. Jordan’s comparative advantages have narrowed over time as external shocks and responses to these shocks have changed the productive structure of Jordan’s economy. This was a problem well before the country faced the COVID-19 pandemic. The Jordanian economy has lost productivity, market access, and, critically, the ability to afford high levels of imports as a share of GDP. Significant efforts toward fiscal consolidation have further constrained aggregate demand, which has slowed non-tradable activity and the ability of the economy to create jobs. Labor market outcomes have worsened over time and are especially bad for women and youth. Looking ahead, this report identifies clear and significant opportunities for Jordan to strengthen new engines of export growth that would enable better overall job creation and resilience, even amidst the continued unpredictability of the pandemic. This report argues that there is need for a paradigm shift in Jordan’s growth strategy to focus more direct attention and resources on activating “agents of change” to accelerate the emergence of key growth opportunities, and that there are novel roles that donor countries can play in support of this.

Hausmann, R., et al., 2022. The Economic Complexity of Namibia: A Roadmap for Productive Diversification .Abstract
After a large growth acceleration within the context of the commodity super cycle (2000-2015), Namibia has been grappling with three interrelated challenges: economic growth, fiscal sustainability, and inclusion. Accelerating technological progress and enhancing Namibia’s knowhow agglomeration is crucial to the process of fostering new engines of growth that will deliver progress across the three targets. Using net exports data at the four-digit level, we estimate the economic complexity of Namibia – a measure of knowhow agglomeration – vis-à-vis its peers. Our results suggest that Namibia’s economy is relatively less complex and attractive opportunities to diversify tend to be more distant. Based on economic complexity metrics, we define a place-specific path for productive diversification, identifying industries with high potential and providing inputs – related to their feasibility and attractiveness in Namibia – for further prioritization. Namibia’s path to structural transformation will likely be steeper than for most peers, calling for a more active policy stance geared towards progressive accumulation of productive capacities, well-targeted “long jumps”, and strengthening state capacity to sort out market failures associated with the process of self-discovery.

Horrible trade-offs in a pandemic: Poverty, fiscal space, policy, and welfare
Hausmann, R. & Schetter, U., 2022. Horrible trade-offs in a pandemic: Poverty, fiscal space, policy, and welfare. World Development , 153. Publisher's VersionAbstract
We analyze how poverty and a country’s fiscal space impact policy and welfare in times of a pandemic. We introduce a subsistence level of consumption into a tractable heterogeneous agent framework, and use this framework to characterize optimal joint policies of a lockdown and transfer payments. In our model, a more stringent lockdown helps fighting the pandemic, but it also 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. Transfer payments help mitigate this trade-off. We show that, ceteris paribus, the optimal lockdown is stricter in richer countries and the aggregate death burden and welfare losses smaller. 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. This is particularly true in societies where a larger fraction of the population is in poverty. We discuss evidence from the literature and provide reduced-form regressions that support the relevance of our main mechanisms. We finally discuss distributional consequences and the political economy of fighting a pandemic.
Hausmann, R., et al., 2022. A Growth Diagnostic of Namibia.Abstract

In the thirty years that have passed since independence, Namibia has been characterized by its over-reliance on its mineral resource wealth, procyclicality of macroeconomic policy, and large income disparities. After an initial decade marked by nation building and slow growth (1990-2000), the Namibian economy embarked on a rapid growth acceleration that lasted 15 years, within the context of the global commodity super cycle. Favorable terms of trade translated into an investment and export boom in the mining sector, which was amplified to the non-tradable sector of the economy through a significant public expenditure spree from 2008 onwards. Between 2000 and 2015 income and consumption per capita expanded at an average annual rate of 3.1%, poverty rates halved, and access to essential public goods expanded rapidly. As the commodity super cycle came to an end and the fiscal space was exhausted, Namibia experienced a significant reversal. Investment and exports plummeted, bringing GDP per capita to contract by 2.1% between 2015-2019. With debt-to-GDP ratios 3.5 times higher than those in 2008, the country embarked on a fiscal consolidation effort which brought the primary fiscal deficit from 6.8% of GDP in 2016 to 0.6% by March 2020. Along all these years, inequality has been endemic and is reflected across demographic characteristics and employment status. At present, a large majority of Namibians are unable to access well-paying formal sector jobs, as these tend to be particularly scarce outside of the public sector. Looking forward, the road to sustained inclusive growth and broad prosperity entails expanding the formal private labor market by diversifying the Namibian economy, while at the same time removing the barriers preventing Namibians from accessing these opportunities inherited from the apartheid.

The Growth Lab at Harvard University has partnered with the Government of Namibia to develop research that results in inputs for a policy strategy aimed at promoting sustainable and inclusive growth. The Growth Diagnostic is a cornerstone of the ongoing research engagement and is meant at providing an overview of the most binding constraints to Namibia’s economic performance and outlining how these relate in a systemic way to the concurrent challenges of growth, fiscal sustainability, and inclusion. 

Inclusive growth in Namibia is currently facing a set of self-reinforcing constraints. The country is missing both the productive capabilities (words) and required skills (letters) to sustain longer periods of growth. The low degree of knowhow agglomeration that can be inferred from its current productive structure – as gathered by the Economic Complexity Index (ECI) – leaves very little opportunities of diversification that can be pursued by redeploying existing skills (low connectedness). Our analysis reveals that Namibia has been able to diversify differentially more that most of its peers given its current set of productive capabilities, but the problem is that the set of adjacent opportunities are neither complex nor plenty. As the marginal cost of acquiring new capabilities tend to be high, the government needs to take a more active role in sorting coordination and information failures associated to the process of productive diversification and self-discovery.

Relatedly, Namibia’s growth prospects are also constrained by a shortage of specialized skills. Three empirical facts derived from econometric analysis of Labor Force Survey statistics point in this direction. First, certain skill-intensive industries and occupations exhibit differentially higher wage premiums. Second, highly educated, and experienced workers face the lowest unemployment rates in the economy, by a wide margin. Third, skill-intensive industries tend to grow less than the rest of the sectors in the economy.

The demand for high skilled foreign workers is high – as proxied by their wage premium. This skill shortage may be constraining not only existing industries but also the development of new engines of growth, limiting access to opportunity for Namibians across all skill levels. Missing skills at the top of the spectrum tends to depress job creation at the bottom. These two constraints – low knowhow agglomeration with poor connectedness and skills shortages – seem to reinforce each other. Using the Scrabble metaphor, Namibia is missing the letters (productive capabilities) and the entire words (more complex products).

Knowhow, by definition, resides in brains of people and it’s embedded in the goods and services a country produces. A broad knowhow-enhancing strategy aimed at targeting efficiency-seeking foreign direct investment (FDI, firms bringing entire new words to Namibia), and migration regulation policies (specific letters needed by more complex industries) is required to ease the binding constraints. Investment promotion efforts shall be targeted to ‘efficiency-seeking’ firms, which tend to take advantage of a competitive factor in the country (efficient labor force, access to international financial markets, infrastructure, etc.) to produce and export to foreign markets. This type of FDI is essentially different from the ‘natural resource-seeking’ investments that have characterized the Namibian economy and pose additional challenges. At the same time, the country would benefit from a more open immigration policy targeted towards high-skill workers. The evidence we have gathered suggests that high-skill foreigners tend to function as complements – rather than substitutes – to Namibian workers: industries with larger shares of high-skill workers tended to pay lower skill workers significantly higher wages. Easing the existing restrictions t labor flows and incentivizing inflows of high-skill foreigners will likely trickle down into the rest of the labor force and enhance the knowhow agglomeration of the Namibian productive ecosystem.

A challenge to productive diversification broadly, and attracting foreign investment and talent more particularly, might be policy uncertainty. Existing levels of policy uncertainty – instability or absence of the adequate regulating environment, worries about potential issues for property rights, inexperience with respect to the efficiency of domestic courts – in Namibia might not be enough to deter investments in resource-based industries, but might be an important hurdle for other type of industries, especially the ones that have a choice regarding their international location. To attract these investments, a simpler and more transparent investment environment, coped a more comprehensive set of international investment treaties, might be necessary.

The report is organized in six sections, including this Executive Summary. Section 2 outlines the Growth Diagnostic methodology. Section 3 provides a summary of the growth trajectory of Namibia and the challenges facing inclusive growth. Section 4 covers the main takeaways of the analysis conducted in each of the branches of the Growth Diagnostics Tree, including those related to access to finance, low social returns, government failures and agglomeration of collective knowhow. Section 5 concludes by highlighting potential binding and providing inputs for a collaborative exploration of why these issues have persisted and become an equilibrium.

Hausmann, R., et al., 2022. Macroeconomic risks after a decade of microeconomic turbulence: South Africa 2007-2020.Abstract
This study analyses the performance of macroeconomic policy in South Africa in 2007–2020 and outlines challenges for policy in the coming decade. After remarkable economic growth in 1997–07, South Africa’s progress slowed dramatically in 2009 with the global financial crisis. Real GDP growth decelerated more than in other emerging markets and mineral exporting peers and never recovered pre-crisis levels. In addition, the budget deficit that provided counter-cyclical support to the economy was never reigned in, leading to a rapidly rising public debt load. The study assesses three accounts of South Africa’s post-GFC growth and fiscal slump: (1) an external story; (2) a macro story; and (3) a microeconomic story. Evidence of strong linkages between micro- and political developments and growth performance is provided.

The new paradigm of economic complexity
Balland, P.-A., et al., 2022. The new paradigm of economic complexity. Research Policy , 51 (3). Publisher's VersionAbstract
Economic complexity offers a potentially powerful paradigm to understand key societal issues and challenges of our time. The underlying idea is that growth, development, technological change, income inequality, spatial disparities, and resilience are the visible outcomes of hidden systemic interactions. The study of economic complexity seeks to understand the structure of these interactions and how they shape various socioeconomic processes. This emerging field relies heavily on big data and machine learning techniques. This brief introduction to economic complexity has three aims. The first is to summarize key theoretical foundations and principles of economic complexity. The second is to briefly review the tools and metrics developed in the economic complexity literature that exploit information encoded in the structure of the economy to find new empirical patterns. The final aim is to highlight the insights from economic complexity to improve prediction and political decision-making. Institutions including the World Bank, the European Commission, the World Economic Forum, the OECD, and a range of national and regional organizations have begun to embrace the principles of economic complexity and its analytical framework. We discuss policy implications of this field, in particular the usefulness of building recommendation systems for major public investment decisions in a complex world.

Lack of progress cannot be solved by a redistributive strategy
Hausmann, R., 2021. Lack of progress cannot be solved by a redistributive strategy. In I. Goldfajn & E. L. Yeyati, ed. Latin America: The Post-Pandemic Decade. Centre for Economic Policy Research Press, pp. 75-87. Publisher's VersionAbstract

Section II, "Policies for sustainable growth", includes dialogues with Mauricio Cárdenas, Marcela Eslava, Ricardo Hausmann, Rodrigo Valdés and Alejandro Werner.

Returning to sustained growth is a key challenge for Latin American economies. This section discusses the causes of the dismal performance of Latin America and the post-Covid policies needed to change this reality. Contributors in this section suggest that the region will witness important rebounds during 2021-2022. The recovery that started in the second half of 2020 gained strength as the economies gradually reopened following rising vaccination rates. Some countries will be reaching 2019 GDP levels in 2021; others, in 2022. However, the concern is that these recoveries will be short-lived. And if global financial conditions become less supportive, the next decade could be quite demanding.

In the medium term, Latin America is expected to exhibit significant scars from Covid, as growth is expected to be permanently below the levels anticipated before the pandemic. But the severe problem of the limited growth potential of the region predates the crisis. And, even for countries that grew more than the Latin American average, the post-pandemic future looks bleaker. The contributors highlight several reasons behind this modest performance. The first and the most commonly cited is macroeconomic mismanagement (high inflation, financial fragility leading to balance-of-payments crises). However, even countries that successfully achieved macroeconomic stabilisation failed to achieve sustained growth. It follows that the forces behind low growth are more complex: the business environment has been feeble; there is a lack of appropriate governance; the natural resource curse applies in some countries, with weak institutions and short-sighted governments with the perception that there is no need for further effort; there are social, political and institutional factors that complicate the building of a consensus around an economic policy framework that sets the foundations for medium-term inclusive growth. In addition, relatively slow technological progress widens the region’s technological gap with the advanced world. Moreover, while the lack of social progress cannot be solved merely with a redistributive strategy, the region’s regressive income distribution and structural poverty are detrimental to growth through their impact on the expected sustainability of economic regimes, as well as, on occasions, pure expropriation risk arising from social tensions. In the meantime, local talent remains undiscovered and undernourished for lack of opportunities.

Most doubt the possibility of implementing successful industrial policies in the region, sceptical that Latin American policymakers could efficiently substitute for the right market signals and incentives, and propose that the development strategy should be largely based on horizontal policies. But some see a role for the state to address the many unexploited externalities, arguing that public goods do not possess the market’s invisible hand to signal where the information about what is needed, the incentives to provide these public goods, and the allocation of resources.

Hausmann, R. & Bustos, S., 2021. New Avenues for Colombia’s Internationalization: Trade in Tasks.Abstract

One of the consequences of COVID-19 is the recognition that many tasks can be done from home. But anything that can done remotely, can be done from abroad.

Given large salary differences between white collar workers across countries, it would make sense for value chains to try to exploit them. This opens an opportunity for Colombia to further promote its integration into the world global value chains and access new markets.

This paper explores the possibility of exporting teleworkable services from Colombia. The goal is to provide useful information to guide strategic interventions to speed-up the development of such service industries in Colombia.

We first introduce a definition of teleworkable jobs and describe its occupations and industries along different dimensions. We show that there are many teleworkable jobs in the US, representing a significant share of industry costs. Then, we show that many industries intensive in teleworkable jobs are currently traded across borders. To quantify Colombia’s advantage providing teleworkable services, we study the cost structure of industries and quantify the potential savings in overall costs if the tasks were performed by Colombians. Given Colombia’s current presence and the density around teleworkable industries we can calculate a proxy of the latent advantage in teleworkable services. We propose an index that summarize these dimensions and rank the potential gains from including telework from Colombia in an industry. We end with a set of policy recommendations to move this agenda forward.

Hausmann, R., et al., 2021. What Economic Complexity Theory Can Tell Us about the EU’s Pandemic Recovery and Resilience Plans. Growth Lab / European Politics and Policy.Abstract

A little over a year ago, the EU’s political leaders agreed on an unprecedented fiscal package – dubbed ‘Next Generation EU’ – to aid Europe’s recovery from the pandemic. Ricardo Hausmann, Miguel Angel Santos, Corrado Macchiarelli and Renato Giacon write that economic complexity theories can provide a useful tool for evaluating whether the recovery and resilience plans submitted by EU member states to receive this funding are well-designed. Assessing the case of Greece, they argue that investments should be tailored toward export-oriented sectors and aim to help close the country’s product complexity gap with other EU states. 

Nedelkoska, L., et al., 2021. The Role of the Diaspora in the Internationalization of the Colombian Economy.Abstract
We studied the geography as well as the demographic and socio-economic characteristics of 1.7 million members of the global Colombian diaspora (34% of the total estimated Colombian diaspora) using census and survey data from major host countries, and 3.5 million Twitter users located around the world presumed to be of Colombian origin. We also studied the locations and industries of Colombian senior managers and directors outside Colombia, using a global database of over 400 million companies. Moreover, we studied the migration journeys, the diaspora’s attachment to Colombia, the level of diaspora engagement and interest in engaging, the intentions to return back home, the interest in diaspora government policy, and the overall sentiment of the diaspora towards Colombia, through a survey which received 11,500 responses from the diaspora in well over 100 countries in less than two months. We additionally interviewed 12 Colombian transnational entrepreneurs and professionals, to understand what attracts them professionally to Colombia, and what may stand in the way of more diaspora engagement and professional growth.

Hausmann, R., et al., 2021. Western Australia – Research Findings and Policy Recommendations.Abstract

The Government of Western Australia (WA), acting through its Department of Primary Industries and Regional Development (DPIRD), invited the Growth Lab of the Center for International Development at Harvard University to partner with the state to better understand and address constraints to economic diversification through a collaborative applied research project. The project seeks to apply growth diagnostic and economic complexity methodologies to inform policy design in order to accelerate productive transformation, economic diversification, and more inclusive and resilient job creation across Western Australia.

This report is organized in six sections, including this brief introduction. Section 2 is an Executive Summary. Section 3 explains the methodologies of Growth Diagnostics and Economic Complexity, including its theoretical foundations and main concepts. Section 4 describes the main findings of the Economic Complexity Report, including a characterization of Western Australia’s complexity profile. This is done at the state, regional, and city levels. Additionally, this section identifies diversification opportunities with high potential and organizes them into groupings to capture important patterns among the opportunities. This section also contextualizes the opportunities further by identifying relevant viability and attractiveness factors that complement the complexity metrics and consider local conditions. Section 5 highlights the main findings of the Growth Perspective Report. This section describes the economic growth process of Western Australia — with a focus on the past two decades — and identifies several issues with the way that growth has occurred. This section highlights three key channels through which negative externalities have manifested: labor market imbalances, pro-cyclicality of fiscal policy, and a misalignment of public goods. The section provides perspectives on the ways in which each of these channels have hampered the quality of growth and explores the deep-rooted factors that underpin these adverse dynamics. Section 6 introduces a policy framework that can be leveraged by WA to capitalize on revealed diversification opportunities and address the factors that impact the quality of the growth process of the state.

Hausmann, R., et al., 2021. Economic Complexity Report for Western Australia.Abstract

The Government of Western Australia (WA), acting through its Department of Primary Industries and Regional Development (DPIRD), invited the Growth Lab of the Center for International Development (CID) at Harvard University to partner with the state to better understand and address constraints to economic diversification through a collaborative applied research project. The project seeks to apply growth diagnostic and economic complexity methodologies to inform policy design in order to accelerate productive transformation, economic diversification, and more inclusive and resilient job creation across Western Australia.

This Economic Complexity Report is organized in six sections, including this brief introduction. Section 2 explains the methodology of economic complexity, including its theoretical foundations and main concepts, as well as the adjustments that were required to obtain the required export data at a subnational level and incorporate the service sector to the analysis. Section 3 describes the structure of the WA economy, identifying its productive capacities and exploring its complexity profile. This is done at the state, regional, and city levels. Section 4 identifies industries with high potential and organizes them into groupings to capture important patterns among the opportunities. Section 5 contextualizes the opportunities further by identifying relevant viability and attractiveness factors that complement the complexity metrics and consider local conditions, as well as a criterion for regional participation in the state-wide diversification strategy. Finally, Section 6 summarizes the main findings of this report and discusses implications for Government of WA strategy and policy toward capitalizing on these revealed opportunities.

Hausmann, R., et al., 2021. Growth Perspective on Western Australia.Abstract

The Government of Western Australia (WA), acting through its Department of Primary Industries and Regional Development (DPIRD), invited the Growth Lab of the Center for International Development at Harvard University to partner with the state to better understand and address constraints to economic diversification through a collaborative applied research project. The project seeks to apply growth diagnostic and economic complexity methodologies to inform policy design in order to accelerate productive transformation, economic diversification, and more inclusive and resilient job creation across Western Australia. As its name implies, this Growth Perspective Report aims to provide a set of perspectives on the process of economic growth in WA that provide insights for policymakers toward improving growth outcomes.

This Growth Perspective Report describes both the economic growth process of Western Australia — with a focus on the past two decades — and identifies several problematic issues with the way that growth has been structured. In particular, this report traces important ways in which policies applied during the boom and subsequent slowdown in growth over the last twenty years have exacerbated a number of self-reinforcing negative externalities of undiversified growth. The report analyzes three key channels through which negative externalities have manifested: labor market imbalances, pro-cyclicality of fiscal policy, and a misalignment of public goods. The report includes sections on each of these channels, which provide perspectives on the ways in which they have hampered the quality of growth and explore the reasons why problematic externalities have become self-reinforcing. In some cases, new issues have emerged in the most recent iteration of WA’s boom-slowdown cycle, but many issues have roots in the long-term growth history of WA.

O'Clery, N., Yildirim, M.A. & Hausmann, R., 2021. Productive Ecosystems and the arrow of development. Nature Communications , 12. Publisher's VersionAbstract

Economic growth is associated with the diversification of economic activities, which can be observed via the evolution of product export baskets. Exporting a new product is dependent on having, and acquiring, a specific set of capabilities, making the diversification process path-dependent. Taking an agnostic view on the identity of the capabilities, here we derive a probabilistic model for the directed dynamical process of capability accumulation and product diversification of countries. Using international trade data, we identify the set of pre-existing products, the product Ecosystem, that enables a product to be exported competitively. We construct a directed network of products, the Eco Space, where the edge weight corresponds to capability overlap. We uncover a modular structure, and show that low- and middle-income countries move from product communities dominated by small Ecosystem products to advanced (large Ecosystem) product clusters over time. Finally, we show that our network model is predictive of product appearances.

Implied Comparative Advantage
Hausmann, R., Stock, D.P. & Yildirim, M.A., 2021. Implied Comparative Advantage. Research Policy . Publisher's VersionAbstract
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 evolution of comparative advantage. We build a simple Ricardian-inspired model and show that hidden information on inter-industry and inter-location relatedness can be captured by simple correlations between the observed structure of industries across locations, or the structure of locations across industries. We then use this recovered information to calculate a measure of implied comparative advantage, and show that it 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). In each of these cases, the deviations between the observed and implied comparative advantage in the past 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.

Place-specific determinants of income gaps: New sub-national evidence from Mexico
Hausmann, R., Pietrobelli, C. & Santos, M.A., 2021. Place-specific determinants of income gaps: New sub-national evidence from Mexico. Journal of Business Research. Publisher's VersionAbstract
The literature on wage gaps between Chiapas and the rest of Mexico revolves around individual factors, such as education and ethnicity. Yet, twenty years after the Zapatista rebellion, the schooling gap has shrunk while the wage gap has widened, and we find no evidence indicating that Chiapas indigenes are worse-off than their likes elsewhere in Mexico. We explore a different hypothesis and argue that place-specific characteristics condition the choices and behaviors of individuals living in Chiapas and explain persisting income gaps. Most importantly, they limit the necessary investments at the firm level in dynamic capabilities. Based on census data, we calculate the economic complexity index, a measure of the knowledge agglomeration embedded in the economic activities at the municipal level. Economic complexity explains a larger fraction of the wage gap than any individual factor. Our results suggest that the problem is Chiapas, and not Chiapanecos.
