Tackling Discrepancies in Trade Data: The Harvard Growth Lab International Trade Datasets

Bilateral trade data informs foreign and domestic policy decisions, serves as a growth indicator, determines tariffs, and is the basis for financial and investment decisions for corporations. Accurate trade data translates into better decision-making. However, the raw bilateral trade data reported by UN Comtrade suffer from two structural problems: reporting differences between country partners and countries reporting in different product classification systems, which require product-level harmonization to compare data across countries. In this paper, we address these challenges by combining a mirroring technique and a data-driven concordance method. Mirroring reconciles importer and exporter differences by imputing country reliability scores and applying a weighted country-pair average to calculate the estimated trade value. We harmonize product classifications across vintages by calculating conversion weights that reflect a product’s market share. The resulting publicly available datasets mitigate issues in raw trade statistics, reducing reporting inconsistencies while maintaining product-level granularity across six decades. 

Industrial policy for competitiveness in the energy transition

Green objectives have reshaped public policy worldwide since the signing in 2015 of the Paris Agreement to limit global warming. Climate policy has moved from being one policy among many to an objective embedded in public policies at every level, including energy, industrial, fiscal, trade, development and foreign policies. However, a clear outcome from this policy shift is yet to be seen, with emissions still rising and climate impacts intensifying. There is also backlash against greening in a charged geopolitical environment.

Nevertheless, the chapters in this volume, written by a range of experts worldwide, show that in many countries and policy areas, green objectives are still driving fundamental changes and many lessons have been learned. The goals of reducing emissions and enhancing economic and societal resilience to climate change will persist as climate impacts become more evident, and as the green transition produces successes at city, regional and national levels. In this context, this Bruegel Blueprint offers a fresh intellectual framework for understanding how the green transition is shaping cross-sectoral impacts across the globe.

De Facto Openness to Immigration

Various factors influence why some countries are more open to immigration than others. Policy is only one of them. We design country-specifc measures of openness to immigration that aim to capture de facto levels of openness to immigration, complementing existing de jure measures of immigration, based on enacted immigration laws and policy measures. We estimate these for 148 countries and three years (2000, 2010, and 2020). For a subset of countries, we also distinguish between openness towards tertiary-educated migrants and less than tertiary-educated migrants. Using the measures, we show that most places in the World today are closed to immigration, and a few regions are very open. The World became more open in the first decade of the millennium, an opening mainly driven by the Western World and the Gulf countries. Moreover, we show that other factors equal, countries that increased their openness to immigration, reduced their old-age dependency ratios, and experienced slower real wage growth, arguably a sign of relaxing labor and skill shortages.

Growth Through Diversification in Hermosillo

In this report, we study Hermosillo’s economic performance and assess critical issues affecting the city’s ability to achieve stronger economic growth. Although Hermosillo is far from experiencing economic stagnation, it fell behind other cities that managed to become successful economic hubs between 2010 and 2020. The main reason behind this trailing growth is Hermosillo’s relatively low diversification and investment dynamics, especially in the manufacturing sector. We apply growth diagnostic testing on various potential constraints to economic growth: logistics, electricity, water, human capital, housing, and transportation. Although none of them have directly constrained economic growth in the past, some are explicit threats to increasing growth in the future, thus catching up with high-performing peers. Electricity, human capital, and logistics are comparative advantages, while water, housing, and transportation are threats. 

In 2025, Mexico is expected to start a new period in its economic history marked by the promise of nearshoring and a new presidential administration. In the past, Mexico has gone through milestones that heavily impacted its economic development path, like the establishment of NAFTA and the China Shock (Hanson, 2010). The rise of Northern Mexico and other regions like El Bajío as global manufacturing hubs has resulted from greater integration with the North American market. This has brought foreign direct investments (FDI) targeted at establishing manufacturing sites primarily to cater to US demand and exports to the rest of the world. Mexico holds high expectations that nearshoring will bring opportunities of the same or greater magnitude. In that context, Hermosillo stands out as a city with the potential to exploit those opportunities and enhance its economic transformation. It is crucial to analyze its binding constraints for economic growth, comparative advantages, and potential concerns to understand how well-positioned Hermosillo is to take advantage of this momentum. 

Following the introduction and a methodological overview, the report is divided into four main sections. Section 3 provides a growth perspective on Hermosillo; Section 4 presents an analysis of growth constraints; Section 5 explains the local diversification challenge in detail; and Section 6 describes strategic policy areas to accelerate growth that result from this growth diagnostic analysis. 

Diagnosing Wyoming’s Workforce Challenges

Wyoming is facing two distinct labor market challenges: in the short-term low workforce availability is a constraint while in the long-term job and wage growth have stagnated. Currently, Wyoming’s labor market is characterized by tightness and employers are struggling to fill positions. However, the current tightness of the labor market is not a phenomenon that is specific to Wyoming but instead is prevalent across the country. What sets Wyoming apart is the lack of growth in employment and wages over the long-term. Understanding these differing dynamics is important because policy responses may attempt to address the short-term issue without considering the underlying structural causes of the long-term dynamics. This will likely be ineffective and not lead to lasting change. For lasting change, the structural issues of the long-term dynamic need to be addressed.

An often-discussed solution is to increase the supply of training and education – this has merits in its own right but will not solve the long-term labor market challenge facing Wyoming. Only 38% of all jobs in Wyoming require tertiary education, the second lowest of any US state. Additionally, our analysis shows that the returns to a tertiary degree in Wyoming are significantly below those of its peers. Unsurprisingly, the lack of demand for tertiary-educated workers leads many young Wyomingites with a tertiary degree to leave the state. Overall, however, Wyoming has become an exporter of well-trained young people. Increasing the supply of tertiary education will not address the underlying structural issues facing the labor market.

A main driver of Wyoming’s lagging performance has been the comparatively low labor productivity in the state. Most of Wyoming’s industries have a lower output per worker than the respective national industry and pay lower wages on average. Industries that fall into this category cover 82.8% of all employment in Wyoming. The few industries in which Wyoming is more productive than the rest of the US are mostly related to natural resource extraction. Wage dynamics of occupations in the state exert a similar pattern where STEM-related occupations have not seen much growth, indicating low demand in the state.

To address the long-term issue, Wyoming needs to create the conditions for a more complex economy that can use the potential of its human capital instead of excessively relying on its natural resources. The challenge is to attract and grow competitive companies in industries with strong demand. A critical factor in doing so is scale. Many more knowledge-intensive industries tend to develop in places that are larger urban agglomerations. Wyoming should focus on the positive forces of agglomeration to develop these industries and make use of the productive potential it has. Creating the conditions for this includes place-based investments and an enabling regulatory framework. In Wyoming, housing regulations have been an important barrier preventing further agglomerations, but efforts are underway to address this barrier.

In the short-term, solutions that are focused on increasing the available labor pool within the state appear most promising in easing the current constraint. This is especially true when they address structural barriers that could persist after the labor market cools off. Our work documents specific recommendations within the areas of childcare, justice-involved individuals, higher education, and out-of-state workers (Section 3.2) that aim to increase the participation from these labor pools in Wyoming’s workforce. These are labor pools that are significant in size and have underutilized potential in terms of labor force participation within the state.

From Products to Capabilities: Constructing a Genotypic Product Space

Economic development is a path-dependent process in which countries accumulate capabilities that allow them to move into more complex products and industries. Inspired by a theory of capabilities that explains which countries produce which products, these diversification dynamics have been studied in great detail in the literature on economic complexity analysis. However, so far, these capabilities have remained latent and inference is drawn from product spaces that reflect economic outcomes: which products are often exported in tandem. Borrowing a metaphor from biology, such analysis remains phenotypic in nature. In this paper we develop a methodology that allows economic complexity analysis to use capabilities directly. To do so, we interpret the capability requirements of industries as a genetic code that shows how capabilities map onto products. We apply this framework to construct a genotypic product space and to infer countries’ capability bases. These constructs can be used to determine which capabilities a country would still need to acquire if it were to diversify into a given industry. We show that this information is not just valuable in predicting future diversification paths and to advance our understanding of economic development, but also to design more concrete policy interventions that go beyond targeting products by identifying the underlying capability requirements. 

Export-led Growth

In this paper, I argue that a focus on exports, both at the intensive margin (where existing products increase their volume), but especially at the extensive margin (where new products start being exported), can help countries figure out what policies to adopt in order to achieve sustained growth. I present five stylised facts about growth and its trends in the decades that followed the Washington Consensus. 

Japan’s Economic Puzzle

This paper examines Japan’s economic performance in recent years, uncovering a narrative that challenges conventional views. Despite slow productivity growth, Japan maintains the highest economic complexity globally due to its sophisticated export portfolio. The study reveals that while Japan has been experiencing a decline in goods export market shares it has had a rise in services exports, particularly in R&D licensing. Furthermore, Japan has significantly increased its net foreign assets and direct investments abroad, resulting in abnormal high returns. These results put together suggest that Japanese firms —perhaps in reaction to a stagnant domestic labor force—are leveraging their extensive knowledge capital by investing and redeploying resources internationally, which are generating these higher returns. The increasing wealth generated abroad results, we show, in an expansion of non-tradable activities which are less productive, driving down aggregate productivity growth. The paper also highlights concerns over declining innovation quality, posing risks to Japan’s future economic performance and its ability to redeploy its accumulated knowledge to enjoy from unusually high returns from their foreign investments. The findings emphasize the need for policy reforms to enhance innovation quality to sustain Japan’s productivity of non-tradable activities and with an immigration policy that may change the downward trend in labor supply. 

On the Design of Effective Sanctions: The Case of Bans on Exports to Russia

We build on Baqaee and Farhi (2019, 2021) and derive a theoretically-grounded criterion that allows targeting bans on exports to a sanctioned country at the level of ∼5000 6-digit HS products. The criterion implies that the costs to the sanctioned country are highly convex in the market share of the sanctioning parties. Hence, there are large benefits from coordinating export bans among a broad coalition of countries. Applying our results to Russia reveals that sanctions imposed by the EU and the US in response to Russia’s invasion of Ukraine are not systematically related to our arguments once we condition on Russia’s total imports of a product from participating countries. We discuss drivers of these differences, and then provide a quantitative evaluation of the export bans to show that (i) they are very effective with the welfare loss typically ∼100 times larger for Russia than for the sanctioners; (ii) improved coordination of the sanctions and targeting sanctions based on our criterion allows to increase the costs to Russia by about 80% with little to no extra cost to the sanctioners; and (iii) there is scope for increasing the cost to Russia further by expanding the set of sanctioned products.

Grants in Wyoming: Constraints and Solutions

Wyoming communities are reliant on grants to fund local priorities, yet the grants system is not effectively meeting the needs of many communities across the state. This problem is central to the growth challenges of many rural economies across the state. Although this problem pre-dates the recent expansion of federal grant programs, the importance of this problem has grown in the last several years as the scale and complexity of federal grant opportunities — particularly discretionary grants — has increased. Wyoming communities are struggling to navigate and benefit from these federal funding opportunities. As of late 2023, the state is significantly underperforming many comparator states in the number of federal grants received and the distribution of federal grants across the state. Grant writers and administrators face a sometimes impossible task in navigating an ever-shifting grants landscape. This is a challenge for local governments across the country but may be especially important in Wyoming due to narrow local tax bases and the rural nature of the state.

Through an eight-month effort combining research and action, we have explored the causes of this problem to inform potential solutions. We have identified four principal constraints that are most to blame for Wyoming’s underperformance: (1) Lack of relationships between communities and funders; (2) Inability to follow changing grant opportunities (esp. federal); (3) Shortage of prioritized community needs and “grant ready” project plans; and (4) Overreliance on “local heroes” – especially for smaller communities. We argue that these challenges are “principal constraints” because they are binding for the largest number of communities, especially smaller communities. However, there are additional constraints that are critical for other communities, especially those that have more experience with accessing state and federal grants. This note summarizes key evidence we have found on each of these principal constraints. These constraints occur early in the grants process, meaning many potentially promising grant opportunities are never pursued. We find that many federal grant programs and discretionary award processes are inconsistent with the realities of scarce staff, resources, and bandwidth of local governments, especially in small communities. However, we find widespread examples and evidence that these constraints can be overcome through actions to enable a strong state-wide network that supports local leaders and grant administrators. Examples of success within the state and in other states show that building the capabilities of the network and enabling all communities to access the knowhow of the network can lead to much better grant outcomes.

The note closes with a discussion of how to target a network-enabling response to the grants problem. We outline a first-best option that centers on establishing regional officers who would be responsible for a set of tasks that would respond directly to the principal constraints identified. This approach would require annual funding, but preliminary analysis shows the return on investment overall would be very high and the approach would have the greatest benefits for smaller communities across the state. Very initial designs have been explored for how to establish such a system building on existing assets. Finally, we compare this first-best approach to alternative approaches that are closer to the current support actions underway in the state.
