This paper investigates if green investors can influence corporate greenhouse gas emissions through capital markets, and if so, whether they have a bigger effect by divesting their stock and limiting polluters’ access to capital, or by acquiring polluters’ stock and engaging with management. We focus on public pension funds, classifying them as green or nongreen based on which political party controlled the fund. To isolate the causal effects of green ownership, we use exogenous variation caused by state-level politics that shifted control of the funds, and portfolio rebalancing in response to returns on non-equity investment. Our main finding is that companies reduced their greenhouse gas emissions when stock ownership by green funds increased and did not alter their emissions when ownership by nongreen funds changed. Other evidence based on activist funds, voting, and shareholder proposals suggests that ownership mattered because of active engagement by green investors and not simply because management adapted proactively to changing shareholder preferences.  We do not find that companies with green investors were more likely to sell off their high-emission facilities (greenwashing). Overall, our findings suggest that (a) corporate managers respond to the environmental preferences of their investors; (b) divestment of polluting companies may lead to greater emissions; and (c) private markets may be able to address environmental challenges independent of government regulation.

In corporate elections, most votes are cast based on recommendations provided by for-profit proxy advisory companies. We develop a model of the voting advice market to explore how competition and demand for advice shape the slant of the advice offered. In the model, advisory firms compete through prices and their advice policies. Shareholders have heterogeneous goals, differing in the weight they place on financial returns versus nonfinancial (“social”) returns, such as reductions in carbon emissions. We assume that investors vote for expressive reasons and may differ in how much they care about voting correctly. In equilibrium, advising firms tailor their advice to reflect the preference of their average investor, which can result in election outcomes being skewed away from those that would prevail if investors had full information. We derive conditions under which advisory firms skew their advice and therefore the election outcome in favor of a minority of investors who have a strong preference for nonfinancial returns. We also study how increasing competition affects equilibrium outcomes.

 This paper investigates if proxy advice leads mutual funds to vote as if they had acquired information on their own. We find, for the period 2004-2017, that advice from Glass Lewis typically moved fund voting in the same direction as self-information, while advice from ISS led funds to vote in the opposite direction. A vote was “self-informed” vote if the fund visited and downloaded information about a company from the SEC’s Edgar website before voting. A fund’s proxy advisor is identified from the format of its regulatory filing. We also find that ISS advice typically made funds more likely to support outcomes preferred by socially responsible investors. We suggest that ISS may have slanted its recommendations in response to pressure from socially responsible investors that wanted to influence ISS’s robo-voting customers.

This paper has been retired and essentially replaced with “Shareholder Democracy and the Market for Voting Advice.”

 This paper studies the market reaction to SEC no-action letter decisions that determine whether a shareholder proposal can be excluded from the proxy statement. We find that over the period 2007-2018, the market reacted positively when the SEC permitted exclusion. Investors appear to have been most skeptical about proposals related to corporate governance and proposals at high-profit firms, suggesting that investors believe some proposals can hurt shareholders by disrupting companies that are already performing well. Disruption appears to come less from fear of the proposal being approved than from distraction of management and the possibility of side deals with activists. The evidence is compatible with the view that managerial resistance is based on a genuine concern that proposals can harm firm value, and suggests that the no-action letter process may increase value by sorting out value-destroying proposals.

Robo-voting is the practice by an investment fund of mechanically voting according to the advice of its proxy advisor in corporate elections, in effect fully delegating its voting decision to its advisor. We examine over 65 million votes cast during the period 2008-2021 by 14,582 mutual funds to describe and quantify the prevalence of robo-voting. Overall, 33 percent of mutual funds robo-voted in 2021; 22 percent with ISS, 4 percent with Glass Lewis, and 6 percent with management. The fraction of funds that robo-voted increased until around 2013 and then stabilized at the current level. Despite the sizeable number of funds that robo-voted, robo-voters controlled only about 1.5 percent of shares on average in recent corporate elections because robo-voters tend to be smaller than other funds. Overall the evidence suggests that robo-voting is more prevalent than its defenders suggest, but may exert less influence on corporate governance than its critics suspect.

The initiative and referendum were intended to curtail the power of organized interest groups, yet business groups account for more spending on ballot measures than any other group by far. Does this mean that direct democracy has become a tool for corporations to buy favorable legislation? This paper reports four types of evidence suggesting that the answer is no: (1) analysis of the content of the universe of state-level initiatives in the United States 1904-2021 shows that anti-business initiatives were more common than pro-business initiatives, both proposed and passed; (2) analysis of contribution patterns for California ballot measures 2000-2020 shows that business groups more often opposed than supported initiatives; (3) abnormal stock returns on election day show that corporate contributors earned positive abnormal returns when initiatives failed and negative abnormal returns when they passed; and (4) for all three types of evidence, business groups fared better with ballot measures proposed by legislatures. I also find similar results for unions.

This paper studies SEC no-action letter decisions that determine whether companies can exclude shareholder proposals from their proxy statements. During the period 2007–2019, the market reacted positively when the SEC permitted exclusion, suggesting that investors viewed those proposals as value-reducing on average. We also find that a company’s stock price drifted down over time while waiting for an SEC decision, suggesting that challenged proposals imposed “distraction” costs on companies. The SEC’s decisions can be predicted by regulatory rules, but are also related to a proposal’s predicted votes—more popular types of proposals were less likely to be removed. We find no robust evidence that no-action letter decisions differed when the SEC was controlled by Democrats versus Republicans.  Taken together, the evidence suggests that managers may be serving shareholder interests in opposing some proposals, and that the no-action letter process may be helping shareholders by weeding out value-reducing proposals.

This paper investigates whether labor unions use proposals opportunistically to influence contract negotiations. Our empirical strategy relies on the observation that proposals have higher bargaining-chip value in contract expiration years, when a new contract must be negotiated. We find that in contract expiration years compared with nonexpiration years, unions increase their proposal rate by one-fifth, particularly proposals concerning executive compensation. Union proposals made during expiration years are less likely to be supported by other shareholders or a leading proxy advisor; the market reacts negatively to union proposals in expiration years; and withdrawn union proposals are accompanied with higher wage settlements. 

 This paper develops a theory of shareholder decision rights over policies and directors affect firm value. The model highlights the distinction between the right to approve and the right to propose. The right to approve is weak; the right to propose is impactful but can help as well as hurt shareholders. Managers have an incentive to deter proposals from activist shareholders by adjusting corporate policy; one might conjecture that external pressure leads them to choose policies more appealing to other shareholders in order to reduce the electoral prospects of activist proposals. However, we show that when deterrence occurs, it is always by moving policy toward the position favored by the activist, even if this reduces shareholder wealth. Our analysis stresses the central role of voting uncertainty in determining the value consequences of shareholder rights and proxy access.

 This paper presents a theory of the allocation of authority in an organization in which centralization is limited by the agent’s ability to disobey the principal. We extend the concept of real authority by observing that not only does the principal have to be informed to give an order, but also that the worker must be willing to follow the order. We show that workers are given more authority when they are costly to replace or do not mind looking for another job, even if they have no better information than the principal. The allocation of authority thus depends on external market conditions as well as the information and agency problems emphasized in the literature. We explore the implications of this insight for hiring policies, managerial styles, and span of control.Toggle Content

This paper studies the announcement returns from 4,764 mergers over the last 57 years in order to shed light on several controversies concerning corporate diversification. One prominent view is that diversification destroys value because of agency problems or internal investment distortions, but we find that combined (acquirer plus target) announcement returns are significantly positive for diversifying mergers throughout the period, and no lower than the returns to related mergers. The returns from diversifying acquisitions declined after 1980, and investors rewarded mergers involving financially constrained firms before but not after 1980, consistent with the idea that the value of internal capital markets declined over time.

 This paper uses recent regulations that have required some companies to increase the number of outside directors on their boards to generate estimates of the effect of board independence on performance that are largely free from endogeneity problems. Our main finding is that the effectiveness of outside directors depends on the cost of acquiring information about the firm: when the cost of acquiring information is low, performance increases when outsiders are added to the board, and when the cost of information is high, performance worsens when outsiders are added to the board. The estimates provide some of the cleanest estimates to date that board independence matters, and the finding that board effectiveness depends on information cost supports a nascent theoretical literature emphasizing information asymmetry. We also find that firms compose their boards as if they understand that outsider effectiveness varies with information costs.

 Corporations use a variety of processes to allocate capital. This article studies the benefits and costs of several common budget procedures from the perspective of a model with agency and information problems. Processes that delegate aspects of the decision to the agent result in too many projects being approved, while processes in which the principal retains the right to reject projects cause the agent to strategically distort his information about project quality. We show how the choice of a decision process depends on these two costs, and specifically on severity of the agency problem, quality of information, and project risk.

This paper develops a theory of organization based on the benefits and costs of internal capital markets. A central assumption is that the transaction cost of raising external funds is greater than the cost of internal funds. The benefit of internal resource allocation is that it gives the firm a real option to avoid external capital markets (and the associated deadweight transaction costs) in more states of the world than single-business firms. The cost is that internal resource flexibility exacerbates an overinvestment agency problem.The optimal focus is determined by trading off the benefit of the option against the cost of overinvestment. In this context, we show how the relative efficiency of integration and separation depends ultimately on assignment of control rights over cash flow. Testable implications are derived for the level of divisional investment, the sensitivity of divisional investment to cash flow, and the diversification discount.

This article develops a dynamic model of a firm in which diversification can be a value-maximizing strategy even if specialization is generally efficient. The central idea is that firms are composed of organizational capabilities that can be profitable in multiple businesses and that diversification is a search process by which firms seek businesses that are good matches for their capabilities. The theory can account for diversified firms trading at discounts compared to single-segment firms, as well as some empirical regularities that are challenging to the agency theory of diversification, such as positive returns to diversification announcements.

This paper investigates the hypothesis that tough antitrust enforcement in the 1960s led firms to engage in diversification programs by preventing them from growing within their own industries. If true, diversification should have occurred more often when large firms merged than when small firms merged because small mergers were less likely to have received antitrust attention. Such a pattern is not observed in a sample of 549 acquisitions from 1968 — diversification was equally common in large and small mergers. Survey evidence shows that diversification movements occurred in other industrialized nations where there was a loose antitrust environment. Both pieces of evidence suggest that antitrust played a minor role in the diversification movement.

 This paper examines the stock market response to acquisition announcements during and immediately after the conglomerate merger wave of the late 1960s. The main finding is that acquirer shareholders benefited from diversification acquisitions, which implies that diversification was not driven by managerial objectives. It is also shown that the market responded positively to bidders who retained the management of target companies and negatively to bidders who replaced target management. This is consistent with the hypothesis that the market favored acquisitions intended to exploit managerial synergies. It suggests that the market disliked takeovers which were motivated to discipline target management. Evidence on buyer and target price-earnings ratios is presented which is inconsistent with the conjecture that conglomerates were able to mislead investors by earnings-per-share manipulation.

 This paper takes a close look at the extraordinarily high pre-merger profit rates of target companies during the conglomerate merger wave. Both publicly-traded and privately-owned targets were significantly more profitable than other firms in their industries and size classes. This implies that managerial discipline was not a predominant takeover motive during the period. However, public targets were less profitable than private targets, and the largest public targets earned only average profits. This suggests that managerial discipline may have been important for the few takeovers that involved large publicly-traded targets. 

Reviews, Overviews, and Comments

 Atanasov and Black (2015) (AB) analyzes potential limitations of empirical studies that use shock-based IV designs, focusing specifically on our article that studies the effect of board independence on firm value (Duchin et al., 2010). With regard to our study, AB raises three concerns with our analysis. This note presents our reaction to AB’s analysis. We agree with two of the concerns in the abstract; it turns out they do not matter for the substance of our analysis. We disagree on the critical issue concerning selection of covariates. As a guide to future research, we highlight the nature of the disagreement, and explain why we believe covariates should be motivated by theory, and why an atheoretical approach to selecting covariates can result in failure to identify effects that actually exist. An important lesson from the analysis is that researchers should exercise caution when including ad-hoc covariates in empirical specifications. We offer concluding thoughts about empirical research and causal inference. (This a response to a working paper version of a paper now forthcoming in Management Science.)
