A Simple Approximation of Tobin's q
提出了一个仅需基本财务和会计信息的简单公式来近似计算托宾q，回归结果显示该近似值能解释托宾q至少96.6%的变异，对需要快速估算托宾q的研究者有用。
This paper develops a simple formula for approximating Tobin's q. The formula requires only basic financial and accounting information. Results of a series of regressions comparing our approximate q values with those obtained via Lindenberg and Ross' (1981) more theoretically correct model indicate that at least 96.6% of the variability of Tobin's q is explained by approximate q.
