| Abstract: | Skills shortage in the fields of Sciences, Technology, Engineering, and Mathematics (STEM) poses a significant challenge for industries globally. This study examines the interrelationship between high school students' gender, their proficiency in Information and Communication Technology (ICT), and their career preferences in the STEM domain. Based on representative data for German teenagers, our study shows that female adolescents are less likely to choose a career in STEM unless they have strong ICT skills in secondary school. The relationship does not hold for male students. Our findings can be explained with evidence that teenagers sort into occupations they believe to be good at and that female teenagers rather underestimate their true potential. Using different empirical approaches, we also show that ICT skills act as a moderator and not as a mediator in the gender-specific choice of training upon graduating from secondary school. |

| Abstract: | Our paper contributes to the discussion about Europe's digital sovereignty. We analyze the relationship between firm performance and the diversification of sourcing countries for imported ICT goods. The analysis is based on administrative data for 3888 German manufacturing firms that imported ICT goods in the years 2010 and 2014. We find that firms that diversify the sourcing of ICT goods across multiple countries perform better than similar firms with a less diversified sourcing structure. This result holds for value added as well as for gross operational surplus as performance measures and for two different indicators of diversification. |

| Abstract: | This empirical study investigates the linkages among entrepreneurship in the form of establishment entry, local banking markets, and broadband availability, focusing on minority areas in the US. Lack of access to banks and lack of competition in the market for small business loans can make it more difficult for an entrepreneur to overcome the liquidity constraint to starting a new business. Broadband internet access can facilitate startups directly by enhancing firm profitability and indirectly by stimulating competition in the loan market, lowering the cost of access to finance, and enabling access to financial capital from fintech lenders. The barriers to new business creation erected by local banking markets are hypothesized to be even higher in minority areas, given the greater difficulty minority entrepreneurs face in raising financial capital. The empirical results show that broadband availability, local bank density, and competition in small business loans all facilitate startups. Broadband lowers barriers for entrepreneurs as hypothesized through both the direct and indirect channels. Broadband availability attenuates the barriers from insufficient access to local banks and lack of competition in small business loans from banks. For some industries, higher bank density and greater loan competition facilitate startups more in minority areas than in mostly white areas. Given that minority areas have many fewer banks per capita and much less loan competition than mostly white counties, the results imply that minority areas face even higher barriers to entrepreneurship from insufficient local formal financial resources. The moderating effect of broadband on local financial constraints applies even more so to Black communities; thus while the barriers for Black entrepreneurs may be higher, access to broadband has a greater alleviating effect on those barriers. Business creation in Hispanic areas also faces obstacles from the local banking environment, but broadband does not appear to help reduce them, although it still has a positive direct effect on entry. Additional evidence shows that broadband helped small businesses in minority areas procure more bank loans. Broadband access can thus help entrepreneurs in general, Blacks in particular, and to a lesser extent Hispanics surmount the liquidity constraint to starting a business. The implications of the results are discussed with reference to current and proposed policy to promote broadband availability, usage, and digital equity. |

| Abstract: | The empirical evidence on how industrial robots affect employment and wages is very mixed. Our meta-study helps to uncover the potentially true effect of industrial robots on labor market outcomes and to identify drivers of the heterogeneous empirical results. By means of a systematic literature research, we collected 53 papers containing 2143 estimations for the impact of robot adoption on wages. We observe only limited evidence for a publication bias in favor of negative results. The genuine overall effect of industrial robots on wages is close to zero and both statistically and economically insignificant. With regard to the drivers of heterogeneity, we find that more positive results are obtained if primary estimations a) include more countries in their sample, b) control for ICT capital, demographic developments, or tenure, c) focus on employees that remain employed in the same sector, d) consider only non-manufacturing industries, e) are specified in long differences, and f) come from a peer-reviewed journal article. More negative effects, in turn, are reported for primary estimations that are i) weighted, ii) aggregated at country level, iii) control for trade exposure, iv) and consider only manufacturing industries. We also find some evidence for skill-biased technological change. The magnitude of that effect is albeit small and less robust than one might expect in view of skill-biased technological change. We find little evidence for data dependence. |

| Abstract: | Using newly digitized data on the growth of the telegraph network in America during 1840-1852, the paper studies the impacts of the electric telegraph on national elections. I use proximity to daily newspapers with telegraphic connections to Washington to generate plausibly exogenous variation in access to telegraphed news from Washington. I find that access to Washington news with less delay significantly increased voter turnout in national elections. For mechanisms, I provide evidence that newspapers facilitated the dissemination of national news to local areas. In addition, text analysis on more than a hundred small-town weekly newspapers from the 1840s shows that the improved access to news from Washington led newspapers to cover more national political news, including coverage of Congress, the presidency, and sectional divisions involving slavery. The results suggest that the telegraph made newspapers less parochial, facilitated a national conversation and increased political participation. I find little evidence that access to telegraphed news from Washington affected party vote shares or Congressmen's roll call votes. |
