We create a broad measure of corporate governance, Gov-Score, based on a new dataset provided by Institutional Shareholder Services. Gov-Score is a composite measure of 51 factors encompassing eight corporate governance categories: audit, board of directors, charter/bylaws, director education, executive and director compensation, ownership, progressive practices, and state of incorporation. We relate Gov-Score to operating performance, valuation, and shareholder payout for 2,327 firms, and we find that better-governed firms are relatively more profitable, more valuable, and pay out more cash to their shareholders. We examine which of the eight categories underlying Gov-Score are most highly associated with firm performance. We show that good governance, as measured using executive and director compensation, is most highly associated with good performance. In contrast, we show that good governance as measured using charter/bylaws is most highly associated with bad performance. We examine which of the 51 factors underlying Gov-Score are most highly associated with firm performance. Some factors representing good governance that are associated with good performance have seldom been examined before (e.g., governance committee meets annually, independence of nominating committee). In contrast, some factors representing good governance that are associated with bad performance have often been examined before (e.g., consulting fees less than audit fees paid to auditors, absence of a staggered board, absence of a poison pill). Gompers, Ishii and Metrick (2003) created G-Index, an oft-used summary measure of corporate governance. G-Index is based on 24 governance factors provided by Investor Responsibility Research Center. These factors are concentrated mostly in one ISS category, charter/bylaws, which we show is less highly associated with good performance than are any of the other seven categories we examine. We document that Gov-Score is better linked to firm performance than is G-Index.

Separation of ownership and control in firms creates information asymmetry problems between shareholders and managers that expose shareholders to a variety of agency risks. This paper investigates the extent to which governance attributes that are intended to mitigate agency risk affect firms' cost of equity capital. We examine governance attributes along four dimensions: (1) financial information quality, (2) ownership structure, (3) shareholder rights, and (4) board structure. We find that firms reporting larger abnormal accruals and less transparent earnings have a higher cost of equity, whereas firms with more independent audit committees have a lower cost of equity. We also find that firms with a greater proportion of their shares held by activist institutions receive a lower cost of equity, whereas firms with more blockholders have a higher cost of equity. Moreover, we find a negative relation between the cost of equity and the independence of the board and the percentage of the board that owns stock. Collectively, the governance attributes we examine explain roughly 8% of the cross-sectional variation in firms' cost of capital and 14 % of the variation in firms' beta. The results support the general hypothesis that firms with better governance present less agency risk to shareholders resulting in lower cost of equity capital.
