Item THE ROLE OF SCIENTISTS AND ENGINEERS IN INVENTIONS AND THEIR ALLOCATION: EVIDENCE FROM JAPAN’S INDUSTRIALIZATION(2024) Yamaguchi, Shotaro; Braguinsky, Serguey; Agarwal, Rajshree; Business and Management: Management & Organization; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)My dissertation seeks to address the role of university-educated scientists and engineers (S&Es) during industrialization, with a particular focus on the sorting of S&Es into invention activities and their allocation process both within and across firms. To achieve this, I delve deeply into the historical context of Japan's industrialization from the late 19th to the early 20th century, a period marked by the simultaneous emergence of multiple heavy manufacturing industries, a higher education system in science and engineering, and the rise of extensively diversified conglomerates known as zaibatsu. Using a manually constructed individual career database encompassing nearly all Japanese university graduates in science and engineering from the cohorts of 1877 to 1920 as an empirical basis, I conduct three independent yet interconnected studies in this dissertation. In Chapter 1, I investigate the factors influencing the sorting of university-educated scientists and engineers (S&Es) into inventors by matching them with archival patent records. I find a strong positive correlation between academic excellence and the likelihood of becoming an inventor as well as invention productivity. These highly skilled individuals significantly contributed to inventions in fields associated with emerging heavy manufacturing industries. I also underscore a strong complementarity between their academic skills and post-graduation job experience, which synergistically facilitated the generation of inventions. In Chapter 2, I delve deeply into the (re-)allocation process of educated plant managers and engineers across establishments within a leading cotton-spinning firm, in conjunction with investment in physical capital. Through detailed analysis of plant-level data on human capital appointments, transfers, and capital investments, I illuminate the endogenous process of internal human capital (re-)allocations in alignment with evolving strategic priorities. Notably, the shift from cost leadership to product differentiation, driven by high-end spinning machines, engendered a three-way complementarity between managerial human capital, engineering human capital, and advanced technologies. In Chapter 3, I examine how S&E university graduates are allocated both externally (moves across different independent firms) and internally (moves across affiliated firms within diversified firms or conglomerates) and their implication for innovation. I demonstrate that internal mobility enhances individual invention performance, whereas external mobility diminishes it. However, these performance differences are primarily attributed to the selection of different quality of human capital. Additional analysis suggests that high-quality human capital tends to enter growing industries through internal mobility and be often placed in managerial positions that grant them to access complementary resources. Overall, my dissertation studies contribute to the literature on strategic human capital, corporate strategy, and economic emergence. I assert that the insights derived from the unique historical context of Japan’s industrialization can not only be applied to current emerging economies but also to new industries in developed countries wherein the supply of specialized talent is scarce and mega firms play a pivotal role in driving innovation.Item Caffeinated Development and Other Essays in Latin American Economic History(2020) Uribe-Castro, Mateo; Wallis, John J; Economics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation consists of three essays. The first one focuses on Colombia after 1850 and measures the impact of the expropriation of Church's assets on political violence. With yearly data on the number of battles per municipality, archival information on the reform, and difference-in-differences, the paper documents a reduction of political violence in places where the Church's assets were expropriated. The paper contests the traditional idea of the expropriation of Church's real estate as a source of political violence. It highlights changes in political competition after the alliance between Conservative factions and the Church was weakened. Specifically, it shows the reduction in political violence was concentrated in municipalities with high political competition and where the Conservative Party was relatively weak. The second essay studies the effect of the first wave of globalization on developing countries' structural transformation, using data from Colombia's expansion of coffee cultivation. Counties engaged in coffee cultivation in the 1920s developed a smaller manufacturing sector by 1973 than comparable counties, despite starting at a similar level in 1912. My empirical strategy exploits variation in potential coffee yields, and variations in the probability to grow coffee at different altitudes. This paper argues that coffee cultivation increased the opportunity cost of education, which reduced the supply of skilled workers, and slowed down structural transformation. Using exogenous exposure to coffee price shocks as instrument, I show that reductions in cohorts' educational attainment led to lower manufacturing activity in the long-run. The effect is driven by both a decrease in demand for education and reductions in public goods. Finally, coffee cultivation during the early 20th Century had negative long-run effects on both individual incomes and poverty rates. The third essay explores how changes in commodities’ prices can have differential effects on school enrollment according to characteristics of crop’s production functions. It compares schooling outcomes in counties that specialize in sugar (a land intensive crop with economies of scale) or coffee (mostly produced in small farms) in Puerto Rico between 1900 and 1930. Sugar price increases lead to increases in enrollment in sugar counties, while coffee price changes have a negative relationship with enrollment in coffee regions.
