Equity ownership gives labor both a fractional stake in a firm's residual cash flows and a voice in corporate governance. Relative to other firms, labor-controlled publicly traded firms deviate more from value maximization, invest less in long-term assets, take fewer risks, grow more slowly, create fewer new jobs, and exhibit lower labor and total factor productivity. Therefore, we propose that labor uses its corporate governance voice to maximize the combined value of its contractual and residual claims, and that this often pushes corporate policies away from, rather than toward, shareholder value maximization.

Stock prices move together more in poor economies than in rich economies. This finding is not due to market size and is only partially explained by higher fundamentals correlation in low-income economies. However, measures of property rights do explain this difference. The systematic component of returns variation is large in emerging markets, and appears unrelated to fundamentals co-movement, consistent with noise trader risk. Among developed economy stock markets, higher firm-specific returns variation is associated with stronger public investor property rights. We propose that strong property rights promote informed arbitrage, which capitalizes detailed firm-specific information.

We observe less efficient capital allocation in countries whose banking systems are more thoroughly controlled by tycoons or families. The magnitude of this effect is similar to that of state control over banking. Unlike state control, tycoon or family control also correlates with slower economic and productivity growth, greater financial instability, and worse income inequality. These findings are consistent with theories that elite-capture of a country’s financial system can embed “crony capitalism.”

We investigate the relationship between management ownership and market valuation of the firm, as measured by Tobin's Q. In a 1980 cross-section of 371 Fortune 500 firms, we find evidence of a significant nonmonotonic relationship. Tobin's Q first increases, then declines, and finally rises slightly as ownership by the board of directors rises. For older firms, there is evidence that Q is lower when the firm is run by a member of the founding family than when it is run by an officer unrelated to the founder.

We document a robust cross‐sectional positive association across industries between a measure of the economic efficiency of corporate investment and the magnitude of firm‐specific variation in stock returns. This finding is interesting for two reasons, neither of which is a priori obvious. First, it adds further support to the view that firm‐specific return variation gauges the extent to which information about the firm is quickly and accurately reflected in share prices. Second, it can be interpreted as evidence that more informative stock prices facilitate more efficient corporate investment.

In a sample of 326 US acquisitions between 1975 and 1987, three types of acquisitions have systematically lower and predominantly negative announcement period returns to bidding firms. The returns to bidding shareholders are lower when their firm diversifies, when it buys a rapidly growing target, and when its managers performed poorly before the acquisition. These results suggest that managerial objectives may drive acquisitions that reduce bidding firms' values.

Complete limit order data from Korea show individual stocks’ demand and supply elasticities correlating negatively in short windows. That is, whenever a stock’s demand is unusually elastic, its supply is unusually inelastic, and vice versa. However, in long windows, individual stocks’ demand and supply elasticities correlate positively. Notably, both fall about 40% with the 1997 Asian Financial Crisis, and remain depressed long after the market and macroeconomic variables recover. A parsimonious model explains both findings with investor information heterogeneity and risk-aversion parameters, fixed in the short-run, being permanently shifted by the crisis.

Disequilibrating macro shocks affect different firms’ prospects differently, increasing idiosyncratic variation in forward-looking stock returns before affecting economic growth. Consistent with most such shocks from 1947 to 2020 enhancing productivity, increased idiosyncratic stock return variation forecasts next-quarter real GDP growth, industrial production growth, and consumption growth both in-sample and out-of-sample. These effects persist after controlling for other leading economic indicators.
