I cover three topics in empirical microeconomics. In the first chapter, titled Investor Attention to Firm versus Market-wide Information Shocks: Evidence from North Korean Missile Tests, I study whether attention towards salient political events leads to underutilization of firm-specific information in the South Korean stock market. I find that companies with earnings surprises in the top quartile experience a 1.6% increase in the abnormal return on the announcement day, but a same-day missile test takes away 70% of the positive response. In the second chapter, titled Does Cultural Proximity Mitigate the Effect of Immigration on Electoral Outcomes? (with Gerard Domènech), we study the effect of immigration on electoral outcomes using individual-level administrative data in Spain. In a multiple instrumentations framework, we find that recent immigrants who arrived within two years are associated with an increase in the vote share of the extremist parties. Such an effect persists for additional two years but dissipates in the long-term. When split by regions of origin, African immigrants have the greatest impact, followed by Latin American immigrants. European immigrants do not affect the extremist vote shares. An analysis of the unemployment rate and the number of children suggests that immigrants tend to assimilate over time. The findings are consistent with the hypothesis that cultural proximity mitigates the political reaction to immigrants. In the third chapter, titled The Effect of Daddy Quota on Gender Labor Market Outcomes (with Petra Niedermeyerova), we study the impact of a father-specific parental leave policy on labor market outcomes in Quebec, Canada. Using a province-level difference-in-difference approach, we find that the so-called daddy quota increases the probability of employment for women and decreases the wage of younger men. The results suggest that the daddy quota promoted equal opportunities for women in the labor market. In a theoretical framework, we show that policy-driven changes in gender norms are consistent with our findings.

Thesis advisor: Thomas Chemmanur / My Ph.D. dissertation consists of three essays. The first essay studies the economic consequence of the current patent screening process on firm performance using a machine-learning approach. Using USPTO patent application data, I apply a machine-learning algorithm to analyze how the current patent examination process in the U.S. can be improved in terms of granting higher quality patents. I make use of the quasi-random assignment of patent applications to examiners to show that screening decisions aided by a machine learning algorithm lead to a 15.5% gain in patent generality. To analyze the economic consequences of current patent screening on both public and private firms, I construct an ex-ante measure of past false acceptance rate for each examiner by exploiting the disagreement in patent screening decisions between the algorithm and current patent examiner. I first show that patents granted by examiners with higher false acceptance rates have lower announcement returns around patent grant news. Moreover, these patents are more likely to expire early. Next, I find that public firms whose patents are granted by such examiners are more likely to get sued in patent litigation cases. Consequently, these firms cut R&D investments and have worse operating performance. Lastly, I find that private firms whose patents are granted by such examiners are less likely to exit successfully by an IPO or an M&A. Overall, this study suggests that the social and economic cost of an inefficient patent screening system is large and can be mitigated with the help of a machine learning algorithm. The second essay studies how investor attention affects various aspects of SEOs. Models of seasoned equity offerings (SEOs) such as Myers and Majluf (1984) assume that all investors in the economy pay immediate attention to SEO announcements and the pricing of SEOs. In this paper, we analyze, theoretically and empirically, the implications of only a fraction of investors in the equity market paying immediate attention to SEO announcements. We first show theoretically that, in the above setting, the announcement effect of an SEO will be positively related to the fraction of investors paying attention to the announcement and that there will be a post-announcement stock-return drift that is negatively related to investor attention. In the second part of the paper, we test the above predictions using the media coverage of firms announcing SEOs as our main proxy for investor attention, and find evidence consistent with the above predictions. In the third part of the paper, we develop and test various hypotheses relating investor attention paid to an issuing firm to various SEO characteristics. We empirically show that institutional investor participation in SEOs, the post-SEO equity market valuation of firms, SEO underpricing, and SEO valuation are all positively related to investor attention. Lastly, we also use the number of SEC EDGAR file downloads as an alternative proxy for investor attention, and our findings are robust to this alternative investor attention measure. The results of our identification tests show that the above results are causal. The third essay studies how the location of a lead underwriter in its network of investment banks affects various aspects of seasoned equity offerings (SEOs). We hypothesize that investment banking networks perform an important economic role in the SEO underwriting process for SEOs, namely, that of information dissemination, where the lead underwriter uses its investment banking network to disseminate information about the SEO firm to institutional investors. Consistent with the above information dissemination role, we show that firms whose SEOs are underwritten by more central lead underwriters are associated with a smaller extent of information asymmetry in the equity market. We then develop testable hypotheses based on the information dissemination role of underwriter networks for the relationship between SEO underwriter centrality and various SEO characteristics, which we test in our empirical analysis. Consistent with the above hypotheses, we find that more central lead SEO underwriters are associated with less negative SEO announcement effects; smaller SEO offer price revisions; smaller SEO discounts and underpricing; higher immediate post-SEO equity valuations for issuing firms; and greater post-SEO long-run stock returns for issuing firms. We also find that SEOs with more central lead underwriters are associated with greater institutional investor participation. Our instrumental variable (IV) analysis using the industry-average bargaining power of underwriters relative to issuers as the instrument shows that the above results are causal. Consistent with greater value creation by more central lead underwriters, we find that more central lead underwriters receive greater compensation. / Thesis (PhD) — Boston College, 2021. / Submitted to: Boston College.

Företags finansiella offentliggöranden når ofta endast ett begränsat antal investerare, vilket resulterar i ökad informationsasymmetri och som ett resultat lägre aktielikviditet. Detta är särskilt framträdande för företag som är mindre till storleken, eftersom dessa företag tenderar att få mindre täckning av traditionella kanaler såsom pressnyheter och analytiker. Samtidigt har företag i allt större utsträckning börjat använda Twitter som en del av sin strategi för investerarrelationer, där Twitter skiljer sig från traditionella investerarrelationer genom att information kan distribueras snabbare och blir mer lättillgängligt. Syftet med denna studie är således att testa om offentliggöranden och ökad spridning av finansiell information på Twitter kan minska informationsasymmetrier och därmed göra marknader mer effektiva för att allokera kapital från investerare till företag. Tidigare studier har studerat sambandet mellan ökad spridning av företagsinformation och dess påverkan på företags finansiella prestation och har funnit att spridning av finansiell information via Twitter påverkar informationsasymmetrin i företagsaktier. Genom att studera svenska små och medelstora företag (SME:s) fyller denna studie ett tidigare forskningsgap där vikten ligger i att studera vilken påverkan Twitter har på mindre företag som är mindre synliga i traditionell media och hos analytiker. Undersökningen har baserats på historiska aktiekurser från Nasdaq som sträcker sig över tidsperioden 2020 till 2022. Företagen som ingick i studien var listade på Nasdaqs First North Growth Market, för vilka datamaterial i form av börsdata och frekvens av Twitter-inlägg har samlats in. För att kvantifiera informationsasymmetri och aktielikviditet används avvikande bid-ask spread (eng. Abnormal bid-ask spread) och Amivest likviditetsratio. Studien har använt en kvantitativ forskningsansats för att visa hur sambandet ser ut mot Twitter och utifrån regressionsanalyser, där ett antal Twittervariabler inkluderats, har frågeställning kunnat studeras. Med hjälp av statistiska hypotesetester och en analys av den teoretiska referensramen med intressentmodellen, effektiva marknadshypoteser och investor recognition hypotheses försöker studien förklara hur informationsasymmetrier påverkar effektiviteten hos den finansiella marknaden och hur det kan motverkas genom ökad synlighet. Studien kunde inte hitta något signifikant samband mellan spridning av finansiell information på Twitter och en minskad informationsasymmetri eller ökad aktielikviditet. Resultatet indikerar att större företag som är mer synliga i medier och därmed har en högre grad av investor recognition har en lägre informationsasymmetri. I resultatet är det tydligt att det är få företag i populationen som använder Twitter aktivt för att sprida finansiell information, och de företag som gör det är inte konsekventa, vilket kan innebära att intressenter söker sig till andra mer pålitliga kanaler under rapportperioder. Slutsatsen lyder att företag inte kan ompaketera information och distribuera den via Twitter för att minska informationsasymmetri, då marknaden redan effektivt har tagit informationen i beaktelse på annat håll. Denna studie är ändå relevant för flertalet intressenter som studerar eller arbetar med investerarrelationer, då den bidrar med intressant information inom området.

Denna studies ändamål är att undersöka hur entreprenörer upplever mötet med finansiärer och om upplevelserna skiljer sig mellan kvinnor och män. För att undersöka detta har elva stycken djupintervjuer gjorts med entreprenörer. Sex av dessa entreprenörer är kvinnor och fem stycken är män. Frågorna är semistrukturerade för att ge entreprenörerna utrymme att på ett naturligt sätt kunna beskriva sina upplevelser. I resultatet visas det hur entreprenörerna beskriver situationer med finansiärer, hur de upplever sig behandlade och hur de känner inför dessa möten. Slutsatsen av studien är att det finns skillnader på hur manliga och kvinnliga entreprenörer blir bemötta av finansiärer. Kvinnorna får utstå situationer som männen aldrig får, exempelvis sexism. De behöver tänka på sitt utseende i högre grad och de använder sig av olika strategier för att hantera den ojämlika situationen. Vi kan även se att kvinnorna upplever situationen som jobbigare än vad män gör. / The purpose of this study is to investigate how entrepreneurs experience the meeting with financiers and whether experiences differ between women and men. To investigate this, eleven in-depth interviews have been conducted with entrepreneurs. Six of these entrepreneurs are women and five are men. The questions are semi structured to give the entrepreneurs space to be able to describe their experiences in a natural way. The result shows how entrepreneurs describe situations with financiers, how they are treated and how they feel about these meetings. The conclusion of the study is that there are differences in how male and female entrepreneurs are being treated by financiers. Women are exposed to situations that men never are, for example sexism. They need to think about their appearance to a greater extent and they use different strategies to cope with the uneven situation. We can also see that women experience the situation as more difficult than men experiance it.

Thesis advisor: Richard Sweeney / The main Investor-Owned Utilities in California charge electricity prices that are way above the social marginal cost of consuming electricity. This results in economic inefficiency which previous studies prove to have negative implications for inequality and to slow down the electrification of the transportation sector. This paper seeks to build on the existing knowledge by investigating how the high electricity prices affect low and high income house-holds’ electric vehicle adoption differently in California, and it aims to quantify the extent of such difference. The results show that EV adoption among low income households would be considerably higher under efficient retail pricing, and that low income households are more negatively affected than their high income counterparts. However, the results relative to high income households specifically are inconclusive, and therefore the extent to which the two income groups are affected differently cannot be determined. Further research should tackle this issue by including additional variables such as income by year and EV quality, as well as more granular gasoline price data. / Thesis (BA) — Boston College, 2023. / Submitted to: Boston College.

The enforcement mechanism of international investment arbitral awards is an es- sential safeguard for resolving investment disputes. Under the existing machinery, the ICSID Convention and the New York Convention provide an effective legal framework for the enforcement of international arbitral awards. Many countries have provided a favorable domestic statutory regime for investor-state arbitral awards enforcement.  With China's accession to the ICSID Convention and the signing of bilateral and multilateral investment treaties with many countries, China has become more open and active in international investment in recent years. At the same time, some legal risks in settling investment disputes have emerged. For instance, one of the most significant issues is whether investor-state arbitral awards can be ef- fectively enforced in the PRC.  Though the New York Convention was primarily designed to enforce commercial arbitral awards, it is widely accepted that it also permits the enforcement of awards against sovereign states. However, it is risky for overseas investors resort- ing enforcement in the PRC based on the New York Convention since China left the commercial reservation clause when acceding to the New York Convention.  Thus, the ICSID Convention is more beneficial for foreign investors when entering into contracts with the PRC. However, the execution of ICSID awards is subject to the domestic law of the enforcement forum, but China does not provide specific domestic legislation that complies with the ICSID Convention. Therefore, some legal obstacles should be carefully considered during the enforcement phase, such as sovereign immunity and public policy.  This thesis focuses on the enforcement regime of investor-state arbitral awards under the ICSID Convention and the New York Convention. It also predicts the legal risks of enforcing investor-state arbitral awards in the PRC, thus putting 2 forward suggestions for overseas investors and for improving the Chinese arbitra- tion legal system.

This study examines how the relation of earnings and payout is influenced by country-level moderators of investor protection and creditor rights. By using an international sample with 42,148 firm-year observations in 3,658 firms during the years 2001-2017, I find that earningspayout relation is strong. Further, I present evidence that the earnings-payout relation is alleviated in weak investor protection and creditor right countries due to the negative influence of dividends. Although share repurchases positively impact the strong earnings-payout relation, the positive effect of share repurchases is weaker compared to the negative one of dividends. As a consequence, in weak investor protection and creditor right countries, the strong earnings-payout relation is alleviated when it is tested with the logit regression.

This thesis investigates the effects football games in major international tournaments have on stock market returns. The major international football tournaments are limited to the FIFA World Cup and the UEFA European Championship, and the games studied are only the finals of these tournaments. The thesis deploys a method of difference in difference with synthetic control groups to capture any effects winning or losing of these games may have on the stock market returns in the following days. The last 22 years of finals in the FIFA World Cup and UEFA European Championship are studied in 11 games and thus 22 treatments. In general, a good fit of the synthetic counterfactuals prior to the event taking place is achieved. The positive and negative events are looked at separately rather than game by game since the distinction between negative and positive events is made by previous literature. All games are treated as equally important since they are all the final of a tournament. The estimated gaps are insignificant for a majority of the games, and no causal relationship between the outcome of finals in international football tournaments and returns on broad stock market indices can be established, possible reasons for this are, among other things, that the indices used in this study is mainly all share indices and large cap indices, which are generally stable.
