## 经济代写|行为金融学代写Behavioral Finance代考|Behavioral Finance: A Novel Approach

Academic research as well as numerous commercial endeavors attempt to quantify the effectiveness of a firm’s corporate governance. The resultant metrics allow users to investigate potential links between corporate governance and a firm’s subsequent operating performance and its stock price behavior.

In a seminal contribution, Gompers et al. (2003) propose the so-called G score which enumerates the number of anti-takeover measures adopted by a firm and document that a portfolio long shares of firms with strong shareholder rights (five or fewer measures and labeled as “democracies”) while shorting shares of firms with weak shareholder rights (fourteen or more measures and labeled as “dictatorships”) generates abnormal returns of $8.5 \%$ per year over the sample period 1990 to 1999. Subsequently, Bebchuk et al. (2009) put forward the $\mathrm{E}$ or entrenchment index which relies on a subset of six of the twenty-four provisions considered in the $\mathrm{G}$ score that are most highly correlated with firm value and stockholder returns. They find that buying a portfolio of stocks of firms with non-entrenched management (a zero E index score) and selling short a portfolio of stocks of firms with entrenched management (a five or six E index score) earned abnormal returns of $7 \%$ annually over the 1990 to 2003 sample.

Although both the $\mathrm{G}$ and $\mathrm{E}$ measures have been widely cited and used, unfortunately the effects of governance on a firm’s operating performance and stock relurns remain unresolved.

## 经济代写|行为金融学代写Behavioral Finance代考|The AGR Metric

A firm’s AGR score measures the overall risk that the firm engages in fraudulent or misleading accounting and governance activities. Using publicly available information, MSCI’s objective is to discriminate between fraudulent and non-fraudulent firms. To do so, it ranks firms by their AGR scores and then groups them ranging from Very Aggressive (bottom 10\%) to Conservative (top 15\%), with the bulk of firms being classified as Aggressive $(25 \%)$ or Average $(50 \%)$.

Being proprietary, the exact algorithm by which a firm’s AGR score is calculated is not publicly available. However, in general, the following five risk categories are considered: (i) corporate governance, (ii) high risk events, (iii) revenue recognition, (iv) expense recognition, and (v) asset-liability valuation. Within each of these risk categories, multiple issues (or “games”) are tabulated. There can be as many as twenty-five issues per category. For example, issues within the revenue recognition category include high operating revenues, large accounts receivables, large inventory, and small unearned revenues. Each issue, in turn, is measured by one or more metrics. For example, corporate governance metrics include the percentage of board directors who are officers, incentive compensation over total compensation for both the firm’s CEO and CFO, and the ratio of CFO to CEO total compensation.
