Technology spillovers across firms affect corporate innovation, productivity, and value, according to prior research, so information about technology spillovers should matter to investors. We argue that technology spillovers increase the complexity and uncertainty of value relevant information about the firm, which makes information processing more costly, discourages it, and thereby increases information asymmetry between insiders and outsiders. We find that not only does information asymmetry increase, but so does avoidance by sophisticated market participants, uncertainty, and insider trading. We also find that investors do not misestimate short-term earnings, but they underestimate long-term earnings, consistent with the higher future stock returns that we also find.

We study the causal effects of analyst coverage on corporate investment and financing policies. We hypothesize that a decrease in analyst coverage increases information asymmetry and thus increases the cost of capital; as a result, firms decrease their investment and financing. We use broker closures and broker mergers to identify changes in analyst coverage that are exogenous to corporate policies. Using a difference‐in‐differences approach, we find that firms that lose an analyst decrease their investment and financing by 1.9% and 2.0% of total assets, respectively, compared to similar firms that do not lose an analyst.

A number of firms in the United Kingdom list without issuing equity and then issue equity shortly thereafter. We argue that this two‐stage offering strategy is less costly than an initial public offering (IPO) because trading reduces the valuation uncertainty of these firms before they issue equity. We find that initial returns are 10% to 30% lower for these firms than for comparable IPOs, and we provide evidence that the market in the firm's shares lowers financing costs. We also show that these firms time the market both when they list and when they issue equity.

We study the effect of investor horizons on corporate behavior. We argue that longer investor horizons attenuate the effect of stock mispricing on corporate policies. Consistent with our argument, we find that when a firm is undervalued, greater long-term investor ownership is associated with more investment, more equity financing, and less payouts to shareholders. Our results do not appear to be explained by long-term investor self-selection, monitoring (corporate governance), or concentration (blockholdings). Our results are consistent with a version of market timing in which mispriced firms cater to the tastes of their short-term investors rather than their long-term investors.

We study the effect of corporate social responsibility (CSR) on shareholder value. We argue that long-term investors can ensure that managers choose the amount of CSR that maximizes shareholder value. We find that long-term investors do increase the value to shareholders of CSR activities, not through higher cash flow but rather through lower cash flow risk. Following prior work, we use indexing by investors and state laws on stakeholder orientation for identification. Our findings suggest that CSR activities can create shareholder value as long as managers are properly monitored by long-term investors.

We study the effect of investor horizons on a comprehensive set of corporate decisions. We argue that monitoring by long-term investors generates decision making that maximizes shareholder value. We find that long-term investors strengthen governance and restrain managerial misbehaviors such as earnings management and financial fraud. They discourage a range of investment and financing activities but encourage payouts. Innovation increases, in quantity and quality. Shareholders benefit through higher profitability that the stock market does not fully anticipate, and lower risk.

We examine whether short sellers in the equity market provide valuable information to investors in the bond market. Using a sample of publicly traded bond data covering the period from 1988 to 2011, we find that firms with high short interest have lower credit ratings and are more likely to have their ratings downgraded. We also find that firms with highly shorted stocks are associated with higher bond yield spreads (about 24 basis points). Evidence of causality from short interest spikes and a natural experiment based on the SEC's Regulation SHO pilot program confirms our findings. Overall, our results suggest that equity short sellers provide predictive information to creditors in the bond market. JEL Classifications: G12; G14. Data Availability: Data are publicly available from the sources identified in the study with the exception of the bond data from Lehman Brothers, which is a proprietary dataset.

We hypothesize that greater information asymmetry causes greater losses to debtholders. To test this, we identify exogenous increases in information asymmetry using the loss of an analyst that results from broker closures and broker mergers. We find that the loss of an analyst causes the cost of debt to increase by 25 basis points for treatment firms compared to control firms, and the rate of credit events (e.g., defaults) is roughly 100–150% higher. These results are driven by firms that are more sensitive to changes in information (e.g., less analyst coverage). The evidence is broadly consistent with both financing and monitoring channels, although only a financing channel explains the impact of the loss of an analyst on firms' cost of debt.

Firms in younger labor markets produce more innovation. We establish this by instrumenting the current labor force with historical births in each local labor market in the United States. Analyses of firms and inventors allow us to rule out unobservable heterogeneity across local labor markets and firms, life cycles, and other effects. Corporate innovation in younger labor markets reflects the innovative characteristics of younger labor forces, and its market value is higher. Younger workers as a group, not merely inventors by themselves, produce more innovation for firms through the labor force channel rather than through a financing or consumption channel.
