We provide novel evidence on gender differences in insider-trading behavior and the profitability of senior corporate executives. On average, both female and male executives make positive profits from insider trading. Males, however, earn significantly more than females in equivalent positions and also trade more than females. These gender differences disappear when we limit the sample to firms in which female trading is relatively high. Collectively, these results suggest that female executives have a disadvantage relative to males in access to inside information, even if they have equal formal status, and informal networks may play an important role in attenuating this disadvantage.

Where legal systems and market forces enforce contracts inadequately, vertical integration can circumvent these transaction difficulties. But, such environments often also feature highly interventionist government, and even corruption. Vertical integration might then enhance returns to political rent-seeking aimed at securing and extending market power. China offers a suitable background for empirical examination of these issues because her legal and market institutions are generally weak, but nonetheless exhibit substantial province-level variation. We report that Chinese firms in the 2000's are more vertically integrated than the U.S. firms in the 1990s. We find that vertical integration is more common where legal institutions are weaker and where regional governments are of lower quality or more interventionist. Further, firms led by insiders with political connection are more likely to be vertically integrated. Finally, vertical integration among politically unconnected firms is associated with elevated per capita GDP level and growth, while vertical integration among politically connected firms is unrelated to local economy performance.

This research examines the relationship between policy uncertainty and mergers and acquisitions (M&As). We find that policy uncertainty is negatively related to firm acquisitiveness and positively related to the time it takes to complete M&A deals. In addition, policy uncertainty motivates acquirers to use stock for payment and to pay lower bid premiums. Acquirers, on average, create larger shareholder value from M&A deals undertaken during periods of high policy uncertainty, which is attributable to their prudence as well as the wealth transfer from the financially constrained targets to acquirers.

We model the pricing implications of screens adopted by socially responsible investors. The model reproduces the empirically observed abnormal return to sin stock and implies a premium for systematic investor boycott risk that affects targeted as well as nontargeted firms. The investor boycott premium is not displaced by litigation risk, measures of neglect effect, illiquidity, industry momentum, or concentration. The investor boycott risk factor is useful in explaining mean returns across industries, and its premium varies with the relative wealth of socially responsible investors and the business cycle.

Recent microstructure research finds that liquidity risk, in particular its information component, plays an important role in explaining the post‐earnings‐announcement drift ( PEAD ). We decompose liquidity risk into an accounting‐associated component and a nonaccounting‐associated component and examine their relative importance in explaining PEAD . Our research is motivated by recent findings that liquidity risk is a systematic risk and earnings quality is negatively associated with liquidity risk. We find that the accounting‐associated component is more strongly related to PEAD returns than is its nonaccounting‐associated counterpart. Further analyses reveal that the relation between accounting‐associated liquidity risk and PEAD returns is weaker for firms with greater analyst following. We also find that in a significant market downturn, the relation between accounting‐associated liquidity risk and PEAD returns becomes more pronounced. Our study is the first to document a liquidity risk‐based role of accounting quality in explaining the PEAD phenomenon. It parses out the PEAD risk premia associated with accounting versus nonaccounting sources and, by so doing, sheds light on the role of accounting quality in shaping the liquidity risk‐ PEAD returns relation.

This study finds that investors price firms' greenhouse gas ( GHG ) emissions as a negative component of equity value, and this valuation discount does not differ between firms that voluntarily disclose to the Carbon Disclosure Project ( CDP ) and nondisclosing firms. We derive the GHG emissions for nondisclosers from an estimation model that incorporates firm characteristics and industry. The finding that investors view CDP amounts and estimates of emissions as equally value‐relevant suggests that equity values reflect GHG information from channels other than the CDP . An event study of investors' response to emission‐related information in firms' 8‐K filings further supports this finding. Economically, our results suggest that, for the median S&P 500 firm, GHG emissions impose a market‐implied equity discount of $79 per ton, representing about one‐half of 1 percent of market capitalization.

Errors and bias are both inherent features of accounting. In theory, while errors discourage bias by lowering the value relevance of accounting, they can also facilitate bias by providing camouflage. Consistent with theory, we find a hump‐shaped relation between a firm's propensity to engage in intentional misstatement and the prevalence of unintentional misstatements in the firm's industry for the whole economy and a majority of the industries. The result is robust to using firms’ number of items in financial statements and exposure to complex accounting rules as alternative proxies for errors and to using the restatement amount in net income to quantify the magnitude of bias and errors. To directly test for the two effects of errors, we show that when errors are more prevalent, the market reacts less to firms’ earnings surprises and bias is more difficult to detect. Our results highlight the imperfectness of accounting, advance understanding of firms’ reporting incentives, and shed light on accounting standard setting.

We examine the implications of short-run and long-run consumption risks on the momentum and long-term contrarian profits and the value premium in a unified economic framework. By introducing time-varying firm cash flow exposures to the short-run and long-run shocks in consumption growth, we find the otherwise standard intertemporal asset pricing model goes a long way toward generating the momentum and long-term contrarian profits and the value premium. The model also reproduces the size effect, the pairwise correlations between the profitabilities of these investment strategies, and the performance of the standard CAPM and the consumption CAPM in explaining these well-documented return behaviors.

We document abrupt increases in retail beer prices just after the consummation of the MillerCoors joint venture, both for MillerCoors and its major competitor, Anheuser‐Busch. Within the context of a differentiated‐products pricing model, we test and reject the hypothesis that the price increases can be explained by movement from one Nash–Bertrand equilibrium to another. Counterfactual simulations imply that prices after the joint venture are 6%–8% higher than they would have been with Nash–Bertrand competition, and that markups are 17%–18% higher. We relate the results to documentary evidence that the joint venture may have facilitated price coordination.

The de novo evolution of protein-coding genes from noncoding DNA is emerging as a source of molecular innovation in biology. Studies of random sequence libraries, however, suggest that young de novo proteins will not fold into compact, specific structures typical of native globular proteins. Here we show that Bsc4, a functional, natural de novo protein encoded by a gene that evolved recently from noncoding DNA in the yeast S. cerevisiae, folds to a partially specific three-dimensional structure. Bsc4 forms soluble, compact oligomers with high β sheet content and a hydrophobic core, and undergoes cooperative, reversible denaturation. Bsc4 lacks a specific quaternary state, however, existing instead as a continuous distribution of oligomer sizes, and binds dyes indicative of amyloid oligomers or molten globules. The combination of native-like and non-native-like properties suggests a rudimentary fold that could potentially act as a functional intermediate in the emergence of new folded proteins de novo.
