Empirical Essays on Finance and Innovation


Book Description

This dissertation consists of three empirical studies in finance and innovation. I study various financial factors affecting innovation such as stock market manipulation and public to private transaction. I also investigate the effect of ownership structure on these public to private transactions. The first study finds that the End-of-day price manipulation is associated with short-termism of the firms orientation, long-term harm to a firms equity values, and commensurate with reduced incentives for employees to innovate. Insider trading, by contrast, enables innovators to achieve exacerbated profits from innovation. Using a sample of suspected manipulation events for all stocks from nine countries over the years 2003-2010, I find evidence consistent with these real impacts of market manipulation on innovation. These findings are not attributable to bad firms innovating less and manipulating more, since the average firm subjected to manipulation in the sample is more innovative during the pre-manipulation period. The second study investigates the effect of going private buyout transactions on the investments in innovation using an international sample of buyout transactions from 36 countries over 1997 to 2011. Patent counts and citations are used to proxy for quantity, quality and economic importance of innovation. The data indicate that the effect of buyouts on innovation is quite sizable in terms of quantity and quality, as both patent counts and citations drop following a buyout. I also find that the number of radical patents (i.e. more scientific) drop as well. When we split the sample into institutional and management buyouts the negative association is only confirmed for institutional buyouts. We find that the negative effect of buyouts on innovation is aggravated in post-2006 period, suggesting that the nature of deals has worsened for innovation over time. The data also show that buyouts have a negative effect on innovation efficiency. The third study considers ownership structure of target firms that are subject to going private buyout transactions, which are often highly leveraged and give rise to potential agency conflicts among existing shareholders. In this study, I examine ownership structure prior to going private transactions in 33 countries around the world from 2002 to 2014.The data indicate strong and consistent evidence that pre-going private ownership is characterized by higher institutional and corporate ownership. Family ownership lowers the probability of a public to private transaction. Stronger creditor rights increase the probability of going private particularly for whole company and institutional buyouts.




Essays on Macro-finance and Innovation


Book Description

This dissertation consists of two chapters of my work on macro-finance and innovation. In particular, it studies the impact of the dynamic process of credit reallocation on aggregate innovative activities. The first chapter introduces the main focus of my dissertation. In addition, it reviews the literature and discusses the contribution of this dissertation.The next chapter builds a model to draw out theoretical predictions. In the model economy, borrowing firms choose whether to innovate or retain a mature technology, while lenders decide their allocation of credit. The credit market is characterized with financial and matching frictions and investigates the consequences of lenders' credit reallocation decisions on borrowers' innovation choices. We posit that the innovation process is time consuming (e.g. due to the length of R&D projects). The different amount of time needed for production with the new and old technology exposes lenders to a liquidity risk. The analysis shows that lenders tend to reallocate credit when they face liquidity risks. We show that an intensification of the credit reallocation process improves the matching between lenders and innovative firms but, overall, it disrupts innovation activities.The final chapter empirically investigates the impact of credit reallocation on innovation and tests the predictions from the model. We use a novel data set on bank balance sheets and the number of patents in Italian (a bank-centered country) local markets (provinces) during a period of great economic growth and tighter banking regulation. We construct measures of credit reallocation following the established literature on job reallocation and examine their effect on innovation. To address the concerns about the endogeneity of credit reallocation in the provinces, we exploit indicators of the geographical diversity of the 1936 Italian Banking regulation. We then estimate a two-stage model that in the first stage projects the rate of credit reallocation in a province onto an indicator of tightness of the banking regulation in the province and in the second stage projects the measure of innovation (the number of patents) onto the value of credit reallocation in the province defined by the tightness of local banking regulation. Consistent with the predictions of the model, we find that an increase in credit reallocation depresses innovative activity while aggregate credit growth helps to expand it. Furthermore, we show that our results are robust across empirical specifications, and carry through when controlling for a broad battery of province characteristics or altering the estimation period.







Essays on Finance of Innovation, Firm Dynamics, and Economic Growth


Book Description

Aggregate productivity, fundamental cause of long-run economic growth, plays a crucial role in determining economic development and living standards of nations. The main source of aggregate productivity growth is technological advances that are the outcomes of firms' and entrepreneurs' innovative activity. Complementary to the growing literature that studies how firm dynamics shape technological change, my dissertation focuses on how financial decisions of these agents affect this process. The three chapters of my dissertation provide theoretical, empirical, and quantitative investigation of the interplay between financial and innovative actions of heterogeneous firms along with its implications on aggregate productivity growth. Chapter one studies the impact of financial system on net firm entry, an important source of aggregate productivity growth. Selective funding of most promising ideas by financial intermediaries creates a trade-off between the mass of entrant firms and their average contribution to aggregate productivity. This chapter highlights the relevance of firm heterogeneity for the relationship between finance and growth, and discusses the theoretical and empirical implications of the resulting trade-off in firm entry. Chapter two also builds on the above mass-composition link, and uses it to study the permanent productivity losses due to sudden stops (SS). The model embeds the main mechanism into a real business cycle small open economy framework to measure the forgone productivity contribution of entrants deprived of funding. The theoretical prediction is that, during SS, smaller yet on average more productive cohorts enter the market. Chilean plant-level data that cover the 1998 SS verify this prediction, while the calibrated model demonstrates the quantitative significance of heterogeneity and selection in measuring the long-run productivity loss. Chapter three focuses on a specific financial intermediary that is especially relevant to innovation and growth, namely venture capital (VC) finance. It studies VC's quantitative impact on firm dynamics and economic growth using a new dynamic equilibrium model of technological change with heterogeneous firms and an explicit VC market. Distinctively, the model incorporates a unique feature of VC firms: their operational knowledge (OK) bundled with their investment. Experiments based on the estimated model highlight the quantitative relevance of OK and analyze policy implications.







Three Essays in Empirical Corporate Finance


Book Description

This dissertation consists of three independent papers dealing with three different research questions in the area of corporate finance. Despite the different topics all three papers have one main commonality: their focus on empirical identification. In the first paper, Competing with Superstars, we investigate the effect of superstar CEOs on their competitors. Exploiting shocks to CEO status due to prestigious media awards, we document a significant positive stock market performance of competitors of superstar CEOs subsequent to an award. The effect is more pronounced for competitors who have not received an award themselves, who are geographically close to an award winner and who are not entrenched. We observe an increase in risk-taking, operating performance and innovation activity of superstars' competitors as potential channels for this positive performance. Our results suggest a positive overall welfare impact of corporate superstar systems due to the incentivizing effect on superstars' competitors. The second paper, Unionization and Corporate Disclosure: Evidence from a Natural Experiment, investigates the effect of unionization on financial reporting quality. We establish causality by applying a regression discontinuity design exploiting the discontinuity generated by labor union elections that pass or fail by a small margin. Unionized firms improve their financial reporting quality by 2.6% the year after the election compared to nonunionized firms. The effect is mainly attributable to companies which understate their income. The effect is more pronounced in states with right to work laws and for companies with higher information asymmetry. Our results suggest that unions monitor companies if it potentially increases their rent seeking profits. In the third paper, Are There Peer Effects In Innovation?, we investigate how companies react to their peers' innovation activities, such as new patents. Exploiting exogenous.




Empirical Essays on Finance and Development


Book Description

(Cont.) For each method of targeting, we examine whether the households identified by that process are more disadvantaged according to several measures of economic well-being than households which were not identified. We conclude that PRAs and PRAs coupled with additional verification successfully identify a population which is measurably poorer in various respects, especially those which are more readily observed. The standard government procedures, however, do not appear to target the very poorest for assistance. Based on this sample, households targeted for government assistance are observationally equivalent to those that are not.







Three Essays in Empirical Corporate Finance


Book Description

"The core of the thesis includes three essays in empirical corporate finance. The first essay examines the relation between mandatory disclosure behavior and legal accountability. In this study, we treat the enactment of the Sarbanes-Oxley Act (SOX) in 2002 as a regulatory event that increases the legal accountability of top executives and compute the filing tones for a large sample of Forms 10-Q and 10-K filings between 1994 and 2017 using textual analysis. We document that the changes in filing tones contain substantial information that is reflected promptly in the capital market. We also show that a structural break exists in the distribution of filing tones around SOX. Firms use a more negative tone in their quarterly mandatory disclosure after SOX. Interestingly, investors exhibit a stronger reaction to per unit change of filing tones during the post-SOX era and we show that changes in investors’ reactions are not merely driven by the systematic changes in tone distribution after SOX. We also document that filing tones are determined by common performance measures, but such relation is weakened after SOX. The second essay studies the impact of the exit of Venture Capitalists (VCs) on innovation by comparing VC backed IPO firms with the non-VC backed. VCs play a significant role in bringing new ventures public by providing financing and consistent monitoring. Prior literature has established mostly a positive correlation between VCs and firm innovation because VCs may preselect more innovative firms to begin with. This study hopes to provide evidence on causal inference with reasonable assumptions from a “reverse treatment” perspective by examining the change in innovation when VCs exit. We treat the initial public offering (IPO) as a proxy for VC’s exit since most VCs exit shortly after IPO due to their limited investment horizon. Using a difference-in-differences framework, we find that VC-backed firms experience a greater drop in Research and Development (R&D) intensity after IPO-exits when compared to those non-VC backed. The third essay revisits the long-debated relation between market competition and firm innovation. While traditionally competition is measured at the industry level with historical data, our study utilizes two new text-based measures of competitive threats developed by Hoberg et al. (2014) and Li et al. (2013) which are both firm-specific and forward-looking. We address the potential endogeneity concerns using instrumental variables along with the propensity score matching of firms that experience an exogenous shock from import competition with those that do not. Our results show that an increase in competition unambiguously promotes firm innovation"--




Essays in Innovation and Entrepreneurial Finance


Book Description

This dissertation consists of three chapters.In Chapter 1 of the dissertation, I contribute to the inconclusive literature on labor empow- erment and corporate innovation. The paper exploits a law that creates Labor-Controlled Firms (LCFs) for identification in a regression discontinuity design using administrative data that link employers, inventors, and patents in Germany. The law mandates that firms with more than 500 or 2,000 employees have a minority (33%) or parity (50%) share of labor-elected directors on their boards, respectively. Local average treatment effects on the number of patents and the forward citation-weighted number of patents per LCF are significantly positive at both the minority and parity cutoffs, although forward citations per patent are significantly negative at the parity cutoff. The results suggest that labor control causes innovative productivity to increase at the expense of a relative shift from exploratory toward exploitative search. Auxiliary tests support this conclu- sion. Labor control insures employed inventors against adverse labor market shocks, increasing firm-related specialization through longer employment spells while reducing the intensive margin of innovative labor supply. Moreover, inventors' marginal income per patent is insensitive to the quality of the patent when the employer is labor-controlled, suggesting a lack of financial incen- tives for exploratory search in LCFs. In Chapter 2, we estimates that shares in Private Investments in Public Equity (PIPEs) offered a discount of 3% for each year during which these shares could not be resold. The discount can be substantially larger in offerings in which marketability is a greater concern. Our estimates make use of the duration of the resale restriction and information about the effects of a regulatory change. In 2008, the SEC amended Rule 144 to shorten the default statutory holding period. Our estimates are smaller than previous estimates and robust to various controls and endogeneity concerns. In Chapter 3, we offer evidence from acquisition decisions that suggests that antitakeover pro- visions (ATPs) may increase firm value when internal corporate governance is sufficiently strong. We document that, in Germany, firms with stronger ATPs, and particularly supermajority provi- sions, are better acquirers. Managers of high-ATP firms create value in acquisitions by making governance-improving deals. They are more likely to engage in acquisitions that reduce their own entrenchment level and less likely to invest in declining industries. The empirical evidence is consistent with a short-termist interpretation. Takeover threats can induce myopic investment decisions, which ATPs can mitigate. They also lead managers to engage more often in value- creating long-term and innovative investing, and increase their sensitivity to investment opportu- nities. Our findings contribute to a growing literature challenging conventional wisdom that the agency-increasing effect of ATPs empirically dominates the myopia-eliminating effect, suggesting that a more contextual view of the value implications of ATPs is necessary.
