Publication Innovation Policies Under Economic Complexity(Growth Lab, 2024-09) Chacua Delgado, Christian; Gadgin Matha, Shreyas; Hartog, Matte; Hausmann, Ricardo; Yildirim, MuhammedRecent geopolitical challenges have revived the implementation of industrial and innovation policies. Ongoing discussions focus on supporting cutting-edge industries and strategic technologies but hardly pay attention to their impact on economic growth. In light of this, we discuss the design of innovation policies to address current development challenges while considering the complex nature of productive activities. Our approach conceives economic development and technological progress as a process of accumulation and diversification of knowledge. This process is limited by the tacit nature of knowledge and by countries’ binding constraints to growth. Consequently, effective innovation policies should be place-based and multidimensional, leveraging countries’ existing capabilities and addressing countries’ current problems. This contrasts policies that lead to economic efficiencies, such as copying other countries’ solutions to problems that countries do not currently have.Publication The Role of the Diaspora in the Internationalization of the Colombian Economy(Center for International Development at Harvard University, 2021-05) Nedelkoska, Ljubica; Assumpcao, Andre; Grisanti, Ana; Hartog, Matte; Hinz, Julian Jakob; Lu, Jessie; Muhaj, Daniela; Protzer, Eric; Saxenian, Annalee; Hausmann, RicardoWe 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.Publication A New Algorithm to Efficiently Match U.S. Census Records and Balance Representativity with Match Quality(Growth Lab, 2024-12) Protzer, Eric; Orazbayev, Sultan; Gomez, Andres; Hartog, Matte; Neffke, FrankWe introduce a record linkage algorithm that allows one to (1) efficiently match hundreds of millions of records based not just on demographic characteristics but also name similarity, (2) make statistical choices regarding the trade-off between match quality and representativity and (3) automatically generate a ground truth of true and false matches, suitable for training purposes, based on networked family relationships. Given the recent availability of hundreds of millions of digitized census records, this algorithm significantly reduces computational costs to researchers while allowing them to tailor their matching design towards their research question at hand (e.g. prioritizing external validity over match quality). Applied to U.S Census Records from 1850 to 1940, the algorithm produces two sets of matches, one designed for representativity and one designed to maximize the number of matched individuals. At the same level of accuracy as commonly used methods, the algorithm tends to have a higher level of representativity and a larger pool of matches. The algorithm also allows one to match harder-to-match groups with less bias (e.g. women whose names tend to change over time due to marriage).Publication Global Trends in Innovation Patterns: A Complexity Approach(Growth Lab, 2024-09) Chacua Delgado, Christian; Gadgin Matha, Shreyas; Hartog, Matte; Hausmann, Ricardo; Yildirim, MuhammedTechnological know-how in a country shapes its growth potential and competitive- ness. Scientific publications, patents, and international trade data offer complementary insights into how ideas from science, technology, and production evolve, combine, and are transformed into capabilities. Analyzing their trajectories enables a more comprehen- sive and multifaceted understanding of the whole innovation process, from generating ideas to internationally commercializing products. We analyze the production patterns in these three domains, documenting the differences between advanced and emerging mar- ket economies. We find that future income, patenting, and publishing growth correlate with the economic complexity indices calculated from these domains. Capabilities em- bedded in the country also shape future diversification opportunities and make the inno- vation process path dependent. Lastly, we also show that diversification opportunities can be inferred across innovation domains.
