We empirically evaluate 20 prominent contributions to a broad range of areas in the empirical corporate finance literature. We assemble the necessary data and then apply a single, simple econometric method, the connected-groups approach of Abowd, Karmarz, and Margolis (1999), to appraise the extent to which prevailing empirical specifications explain variation of the dependent variable, differ in composition of fit arising from various classes of independent variables, and exhibit resistance to omitted variable bias and other endogeneity problems. In particular, we identify and estimate the role of observed and unobserved firm- and manager-specific characteristics in determining primary features of corporate governance, financial policy, payout policy, investment policy, and performance. Observed firm characteristics do best in explaining market leverage and CEO pay level and worst for takeover defenses and outcomes. Observed manager characteristics have relatively high power to explain CEO contract design and low power for firm focus and investment policy. Estimated specifications without firm and manager fixed effects do poorly in explaining variation in CEO duality, corporate control variables, and capital expenditures, and best in explaining executive pay level, board size, market leverage, corporate cash holdings, and firm risk. Including manager and firm fixed effects, along with firm and manager observables, delivers the best fit for dividend payout, the propensity to adopt antitakeover defenses, firm risk, board size, and firm focus. In terms of source, unobserved manager attributes deliver a high proportion of explained variation in the dependent variable for executive wealth-performance sensitivity, board independence, board size, and sensitivity of expected executive compensation to firm risk. In contrast, unobserved firm attributes provide a high proportion of variation explained for dividend payout, antitakeover defenses, book and market leverage, and corporate cash holdings. In part, these results suggest where empiricists could look for better proxies for what current theory identifies as important and where theorists could focus in building new models that encompass economic forces not contained in existing models. Finally, we assess the relevance of omitted variables and endogeneity for conventional empirical designs in the various subfields. Including manager and firm fixed effects significantly alters inference on primary explanatory variables in 17 of the 20 representative subfield specifications.

We examine how a firm designs capital allocation and managerial compensation schemes to motivate a privately informed manager to (i) engage in innovative activity to search for, and (ii) guide the firm to invest in, a new investment project. We show that relative to the first-best, the firm allocates too little capital and provides too few incentives for the manager to expend innovative effort; the manager may violate the NPV rule by investing the allocated capital in a project with negative productivity. We provide several novel predictions that help identify firms that are likely to innovate and managers who are likely to follow the NPV rule. We also show that uncertainty and incentive pay can be positively related.

This paper investigates the value effect of large investors through their impact on corporate investment policy using a sample of listed firms in the Chinese stock market where large shareholdings and concentrated ownership are a norm. We find that the impact of capital expenditures on firm value is closely related to the level of large shareholdings (non-tradable or state shareholdings). Capital expenditures are negatively associated with firm value if firms are controlled by entrenched large shareholders. Although there is a general tendency of over-investment, the negative impact of over-investment is cancelled out if firms are controlled by incentive-aligned large shareholders. We also find that, the incentive-alignment effect of large investors is stronger in scenarios where agency conflicts are more intensified. Our findings suggest that capital investment is an important channel through which the value effect of large investors is achieved.

We consider the optimal intertemporal consumption and investment policy of a CARA investor who faces ¯xed and/or proportional transaction costs when trading multiple stocks. We show that when the stock returns are independent, the optimal investment policy in each stock is for the investor to keep the dollar amount invested in the stock between two constant levels and upon reaching one of these thresholds, to trade to the corresponding optimal targets. An extensive analysis of the optimal policy is conducted. This analysis reveals the signi¯cant relevance of transaction costs to the predictability and trading volume literature. We also obtain some seemingly counterintuitive results. For example, conditional on positive investment in a stock, as transaction costs increase, the average amount invested in the stock increases.
