    The Effect of Institutional Factors on the Value of Corporate Diversification

    (2012-09-04) Kuppuswamy, Venkat; Serafeim, Georgios; Villalonga, Belen

    Using a large sample of diversified firms from 38 countries we investigate the influence of several national-level institutional factors or 'institutional voids' on the value of corporate diversification. Specifically, we explore whether the presence of frictions in a country's capital markets, labor markets, and product markets, affect the excess value of diversified firms. We find that the value of diversified firms relative to their single-segment peers is higher in countries with less efficient capital and labor markets, but find no evidence that product market efficiency affects the relative value of diversification. These results provide support for the theory of internal capital markets that argues that internal capital allocation would be relatively more beneficial in the presence of frictions in the external capital markets. In addition, the results show that diversification can be beneficial in the presence of frictions in the labor market.

    The Stock Selection and Performance of Buy-Side Analysts

    (2012-11-09) Groysberg, Boris; Healy, Paul; Serafeim, Georgios; Shanthikumar, Devin

    Prior research on equity analysts focuses almost exclusively on those employed by sell-side investment banks and brokerage houses. Yet investment firms undertake their own buy-side research, and their analysts face different stock selection and recommendation incentives than their sell-side peers. We examine the selection and performance of stocks recommended by analysts at a large investment firm relative to those of sell-side analysts from mid-1997 to 2004. We find that the buy-side firm's analysts issue less optimistic recommendations for stocks with larger market capitalizations and lower return volatility than their sell-side peers, consistent with their facing fewer conflicts of interest and having a preference for liquid stocks. Tests with no controls for these effects indicate that annualized buy-side Strong Buy/Buy recommendations underperform those for sell-side peers by 5.9% using market-adjusted returns and by 3.8% using four-factor model abnormal returns. However, these findings are driven by differences in the stocks recommended and their market capitalization. After controlling for these selection effects, we find no difference in the performance of the buy- and sell-side analysts' Strong Buy/Buy recommendations.

    Does Mandatory IFRS Adoption Improve the Information Environment?

    (2012-11-09) Horton, Joanne; Serafeim, Georgios; Serafeim, Ioanna

    More than 120 countries require or permit the use of International Financial Reporting Standards (‘IFRS’) by publicly listed companies on the basis of higher information quality and accounting comparability from IFRS application. However, the empirical evidence about these presumed benefits are often conflicting and fail to separate between information quality and comparability. In this paper we examine the effect of mandatory IFRS adoption on firms’ information environment. We find that after mandatory IFRS adoption consensus forecast errors decrease for firms that mandatorily adopt IFRS relative to forecast errors of other firms. We also find decreasing forecast errors for voluntary adopters, but this effect is smaller and not robust. Moreover, we show that the magnitude of the forecast errors decrease is associated with the firm-specific differences between local GAAP and IFRS. This finding suggests that it is IFRS adoption rather than a correlated unobservable factor that is causing forecast errors to decrease. Exploiting individual analyst level data and isolating settings where analysts would benefit more from either increased comparability or higher quality information, we document that the improvement in the information environment is driven both by information and comparability effects. These results suggest that mandatory IFRS adoption has improved the quality of information intermediation in capital markets and as a result firms’ information environment by increasing both information quality and accounting comparability.

    WHAT DRIVES CORPORATE SOCIAL PERFORMANCE? THE ROLE OF NATION-LEVEL INSTITUTIONS

    (2012-11-02) Ioannou, Ioannis; Serafeim, Georgios

    Based on Whitley's "National Business Systems" (NBS) institutional framework (Whitley 1997, 1999), we theorize about and empirically investigate the impact of nation-level institutions on firms' corporate social performance (CSP). Using a sample of firms from 42 countries spanning seven years, we construct an annual composite CSP index for each firm based on social and environmental metrics. We find that the political system, followed by the labor and education system, and the cultural system are the most important NBS categories of institutions that impact CSP. Interestingly, the financial system appears to have a relatively less significant impact. We discuss implications for research, practice, and policy-making.

    Resources or Power? Implications of Social Networks on Compensation and Firm Performance

    (2012) Horton, Joanne; Millo, Yuval; Serafeim, Georgios

    Using a sample of 4,278 listed UK firms, we construct a social network of directorship-interlocks that comprises 31,495 directors. We use social capital theory and techniques developed in social network analysis to measure a director's connectedness and investigate whether this connectedness is associated with their compensation level and their firms overall performance. We find connectedness is positively associated with compensation and with the firm's future performance. The results do not support the view that executive and outside directors use their connections to rent extract. Rather the company compensates these individuals for the resources these better connections provide to the firm.

    The Role of the Corporation in Society: An Alternative View and Opportunities for Future Research

    (2014-12-12) Serafeim, Georgios

    A long-standing ideology in business education has been that a corporation is run for the sole interest of its shareholders. I present an alternative view where increasing concentration of economic activity and power in the world’s largest corporations, the Global 1000, has opened the way for managers to consider the interests of a broader set of stakeholders rather than only shareholders. Having documented that this alternative view better fits actual corporate conduct, I discuss opportunities for future research. Specifically, I call for research on the materiality of environmental and social issues for the future financial performance of corporations, the design of incentive and control systems to guide strategy execution, corporate reporting, and the role of investors in this new paradigm.

    Market Competition, Earnings Management, and Persistence in Accounting Profitability Around the World

    (2014-11-25) Healy, Paul; Serafeim, Georgios; Srinivasan, Suraj; Yu, Gwen Gwen

    We examine how cross-country differences in product, capital, and labor market competition, and earnings management affect mean reversion in accounting return on assets. Using a sample of 48,465 unique firms from 49 countries, we find that accounting returns mean revert faster in countries where there is more product and capital market competition, as predicted by economic theory. Country differences in labor market competition and earnings management are also related to mean reversion in accounting returns—but the relation varies with firm performance. Country labor competition increases mean reversion when unexpected returns are positive, but dampens it when unexpected returns are negative. Accounting returns in countries with higher earnings management mean revert more slowly for profitable firms and more rapidly for loss firms. Thus, earnings management incentives to slow or speed up mean reversion in accounting returns are accentuated in countries where there is a high propensity for earnings management. Overall, these findings suggest that country factors explain mean reversion in accounting returns and are therefore relevant for firm valuation.

    What Factors Drive Analyst Forecasts?

    (2011) Groysberg, Boris; Healy, Paul; Nohria, Nitin; Serafeim, Georgios

    A firm's competitive environment, its strategic choices, and its internal capabilities are considered important determinants of its future performance. Yet there is little evidence on whether analysts' forecasts of firm performance actually reflect any of these factors and which are considered most important. We use survey data from 967 analysts ranking 837 companies to judge how their forecasts are related to evaluations of firms' industry competitiveness, strategic choices, and internal capabilities. Forecasts are generally associated with many of the factors that money managers rate as important in their assessments of analyst contributions, including industry growth and competitiveness, low-price strategy, strategy execution, top management quality, innovation, and performance-driven culture. We also find wide variation across variables for ratings consistency among analysts covering the same firm. On average, consistency is higher for sell-side than buy-side analysts, consistent with sell-side analysts facing greater incentives to herd.

    Chief Sustainability Officers: Who Are They and What Do They Do?

    (2014-11-06) Miller, Kathleen; Serafeim, Georgios

    While a number of studies document that organizations go through numerous stages as they increase their commitment to sustainability over time, we know little about the role of the Chief Sustainability Officer (CSO) in this process. Using survey and interview data we analyze how a CSO’s authority and responsibilities differ across organizations that are in different stages of sustainability commitment. We document increasing organizational authority of the CSO as organizations increase their commitment to sustainability moving from the Compliance to the Efficiency and then to the Innovation stage. However, we also document a decentralization of decision rights from the CSO to different functions, largely driven by sustainability strategies becoming more idiosyncratic at the Innovation stage. The study concludes with a discussion of practices that CSOs argue to accelerate the commitment of organizations to sustainability.

    Pay for Environmental Performance: The Effect of Incentive Provision on Carbon Emissions

    (2012-12-07) Eccles, Robert; Ioannou, Ioannis; Li, Shelley Xin; Serafeim, Georgios

    Corporations are increasingly under pressure to improve their environmental performance and to account for potential risks and opportunities associated with climate change. In this paper, we examine the effectiveness of monetary and nonmonetary incentives provided by companies to their employees in order to reduce carbon emissions. Specifically, we find evidence that the use of monetary incentives is associated with higher carbon emissions. This result holds both in cross-sectional and time-series analysis. Moreover, we find that the use of nonmonetary incentives is associated with lower carbon emissions. Consistent with monetary incentives crowding out motivation for pro-social behavior, we find that the effect of monetary incentives on carbon emissions is mitigated when these incentives are provided to employees with formally assigned responsibility for environmental performance. Furthermore, by employing a two-stage multinomial logistic model, we provide insights into factors affecting companies’ decisions on incentive provision, as well as showing that the impact of monetary incentives on carbon emissions remains significant even when we control for potential selection bias in our sample.
