This study investigates the liquidity effects of reverse stock splits using bid-ask spread, trading volume, and the number of nontrading days as proxies for the liquidity of the stock. Results indicate a decrease in bid-ask spread and an increase in trading volume after reverse splits. More importantly, the number of nontrading days significantly declines following reverse splits. For the control group, however, no such changes are observed. These results suggest that reverse splits enhance the liquidity of the stock.

We analyze the determinants of replacement investment decisions in a contingent claims model with maintenance and operation cost uncertainty. We find that the optimal time between replacements is increasing in the volatility of cost, the purchase price of a new asset, and the corporate tax rate; and is decreasing in the systematic risk of cost, the salvage value of the asset, and the investment tax credit. The optimal time between replacements can either increase or decrease with an increase in the depreciation rate. Extensions of the model to examine the effects of technological and tax policy uncertainty on replacement investment decisions give intuitive, but striking results. Uncertainty about the arrival of a technological innovation that would decrease maintenance and operation cost results in a significant decrease in replacement investment. Uncertainty in a tax law change that would encourage investment decreases current investment; and uncertainty in a tax law change that would discourage investment increases current investment.
