Credit Constraints and Stock Price Volatility

Working Paper: CEPR ID: DP6310

Authors: Galina B. Hale; Assaf Razin; Hui Tong

Abstract: This paper addresses how creditor protection affects the volatility of stock market prices. Credit protection reduces the probability of oscillations between binding and non-binding states of the credit constraint; thereby lowering the rate of return variance. We test this prediction of a Tobin?s q model, by using cross-country panel regression on stock price volatility in 40 countries over the period from 1984 to 2004. Estimated probabilities of a liquidity crisis are used as a proxy for the probability that credit constraints are binding. We find support for the hypothesis that institutions that help reduce the probability of oscillations between binding and non-binding states of the credit constraint also reduce asset price volatility.
