How do consumer credit markets affect the allocation of workers to firms, output, and labour productivity? We address this question in two steps. First, we use new micro-data to estimate empirical elasticities of job search patterns to credit. Second, we estimate our novel theory of sorting under risk aversion to match these elasticities, and then we conduct aggregate counterfactuals. Empirically, we show that an increase in credit limits worth 10% of prior annual earnings allows individuals to take 0.33 weeks longer to find a job. Conditional on finding a job, they earn 1.85% more and work at higher paying firms. We also find that young and high-utilization individuals are more responsive to credit. Theoretically, we integrate risk aversion and borrowing into a model with worker and firm heterogeneity. We estimate the model to match our new empirical elasticities, and we then measure how the credit expansion from 1964 to 2004 affected sorting and output. Sorting improves as credit expands since constrained workers—in particular constrained, young, high human capital workers—find more capital-intensive jobs.

We compare the growth and responsiveness to demand shocks of post-initial public offering (IPO) firms and their private counterparts. Using multiple measures of myopia and multiple ways to match IPO firms with private firms, we do not find evidence of myopic behavior by public firms. IPO firms respond more to investment opportunities and have higher productivity in their early public years. Our results on public firms’ sensitivity to growth opportunities hold under several robustness tests, including when we consider firms’ total growth including acquisitions. The results show the importance of matching public to private firms early in their life.

We examine whether industry product market conditions are important in assessing the benefits and costs of chief executive officer (CEO) power. We find that firms are more likely to have powerful CEOs in high demand product markets where firms are facing entry threats. In these markets, investors react favorably to announcements granting more power to CEOs, and CEO power is associated with higher market value, sales growth, investment, advertising, and the introduction of more new products. Our results remain significant when addressing the endogeneity of CEO power by instrumenting CEO power with past non-CEO executive and director sudden deaths.

We study how risk management through hedging affects firms and competition among firms in the life insurance industry, an industry with over 7 trillion in assets and over 1,000 private and public firms. We examine firms after a staggered state-level reform that reduces the costs of hedging by granting derivatives superpriority in case of insolvency. We show that firms that are likely to face costly external finance increase hedging and reduce risk and the probability of receivership. Firms that are likely to face costly external finance also lower prices, increase policy sales, and increase their market share post-reform.

We examine how consumer credit affects entrepreneurship by linking three million earnings and pass-through tax records to credit reports. In the cross-section, we show that self-employment without employees and employer firm ownership increase monotonically with credit limits and credit scores. We then isolate individuals who have had discrete increases in credit limits after the exogenous removal of bankruptcy flags to measure the effects of personal credit on entrepreneurship. Following bankruptcy flag removal, individuals are more likely to start a new employer business and borrow extensively. Those who own businesses with employees borrow $40,000 more after bankruptcy flag removal, a 33% gain relative to the sample average.

We empirically establish that unemployed individuals maintain significant access to credit and that upon a layoff, the unconstrained borrow while the constrained default and delever. Motivated by these findings, we develop a theory of credit lines and labor income risk to analyze optimal transfers to the unemployed. Since credit lines offer fixed interest rates and limits, credit lines are unresponsive to layoffs and provide greater consumption insurance relative to when debt is repriced period by period. At US levels of credit lines, the government can optimally reduce transfers to the unemployed, whereas this is not true when debt is counterfactually repriced period by period.

We study how firms differ from their competitors using new time-varying measures of product similarity based on text-based analysis of firm 10-K product descriptions. This year-by-year set of product similarity measures allows us to generate a new set of industries in which firms can have their own distinct set of competitors. Our new sets of competitors explain specific discussion of high competition, rivals identified by managers as peer firms, and changes to industry competitors following exogenous industry shocks. We also find evidence that firm R&D and advertising are associated with subsequent differentiation from competitors, consistent with theories of endogenous product differentiation.

ABSTRACT We examine how product market competition affects firm cash flows and stock returns in industry booms and busts. Our results show how real and financial factors interact in industry business cycles. In competitive industries, we find that high industry‐level stock market valuation, investment, and financing are followed by sharply lower operating cash flows and abnormal stock returns. Analyst estimates are positively biased and returns comove more. In concentrated industries these relations are weak and generally insignificant. Our results are consistent with participants in competitive industries not fully internalizing the negative externality of industry competition on cash flows and stock returns.

ABSTRACT We examine the effect of industry life‐cycle stages on within‐industry acquisitions and capital expenditures by conglomerates and single‐segment firms controlling for endogeneity of organizational form. We find greater differences in acquisitions than in capital expenditures, which are similar across organizational types. In particular, 36% of the growth recorded by conglomerate segments in growth industries comes from acquisitions, versus 9% for single‐segment firms. In growth industries, the effect of financial dependence on acquisitions and plant openings is mitigated for conglomerate firms. Plants acquired by conglomerate firms increase in productivity. The results suggest that organizational forms' comparative advantages differ across industry conditions.

ABSTRACT We develop a profit‐maximizing neoclassical model of optimal firm size and growth across different industries based on differences in industry fundamentals and firm productivity. In the model, a conglomerate discount is consistent with profit maximization. The model predicts how conglomerate firms will allocate resources across divisions over the business cycle and how their responses to industry shocks will differ from those of single‐segment firms. Using plant level data, we find that growth and investment of conglomerate and single‐segment firms is related to fundamental industry factors and individual segment level productivity. The majority of conglomerate firms exhibit growth across industry segments that is consistent with optimal behavior.
