Forty-nine states and the District of Columbia enacted legislation reducing interstate banking restrictions between July 1982 and April 1993. For these 50 banking bills, deregulation increased the average price of bank stocks. Returns vary cross-sectionally by firm characteristics, regulatory features, and economic conditions. Returns are positively related to the characteristics of acquisition targets. Furthermore, returns are positively related to legislative features that increase the bargaining power of potential targets and economic conditions that are likely to encourage bank acquisition. These findings are consistent with the relaxation of geographic restrictions increasing activity in the corporate control market.

This paper uses both an ARIMA transfer-function intervention model and a panel data analysis to examine the effect of the Ohio deposit insurance crisis in 1985 on the pricing of six-month retail certificates of deposit (CDs) for federally-insured Ohio banks and savings and loans. Adjusting for pricing reactions due to changes in market rates, we find a significant, unanticipated rise in CD-rate premiums on the initial event week of the crisis that continued for approximately seven weeks. Consistent with a contingent insurance guarantee hypothesis, rate premiums are found to be risk based.

We examine the returns of stocks in Cowles Industrial Index before and after the introduction of personal income taxes in 1917. This is distinct from earlier studies because we cross‐sectionally analyze the relationship between the returns of the individual stocks and measures of tax‐loss selling potential and size. We find that excess returns at the turn‐of‐the‐year and for the month of January were not significant until after 1917. These results provide strong support for the tax‐loss selling hypothesis as an explanation for the January seasonal in the returns of small firms.
