Abstract Using euro conversion as the trigger, we examine what drives volume and spread changes when stock exchanges compete. Results show average trading costs on European exchanges decrease almost 9%, and turnover increases over 30%. Trading costs decline or remain unchanged on all exchanges, but volume deteriorates in some markets and improves in others. Frankfurt, Paris, London, and Milan are winners, while Madrid and Brussels lose volume. We examine the role of the spread-volume relation, firm characteristics, exchange trading rules, and country-level factors in determining these outcomes. Results suggest that euro conversion prompted competition by increasing transparency in market prices.

We analyze the impact of sovereign wealth fund (SWF) investments on firm values and provide evidence consistent with the tradeoff between the monitoring and lobbying benefits versus tunneling and expropriation costs of SWFs as blockholders. The data show significant positive (negative) returns to announcements of SWF investments (divestments). The returns are non-monotonic, first rising (falling) and then falling (rising) with the share sought (sold) for investments (divestments). Moreover, we find that SWFs are often active investors. Slightly more than half of the target firms experience one or more events indicative of SWF monitoring activity or influence.

This paper considers the impact of Regulation Fair Disclosure (FD) on firms’ information environments and costs of capital. For NYSE/Amex firms we find little evidence of a change in the cost of capital attributable to Regulation FD. For Nasdaq firms we find that Regulation FD increased firms’ costs of capital by 10–19 basis points per annum though the statistical significance of this change is modest for some of our models. We also show substantial cross-sectional variation in the cost of capital changes. We find that cost of capital changes were negatively related to both pre-regulation firm size and PIN. In addition to the findings regarding Regulation FD, this research contributes to a growing literature that documents links between firms’ information environments and their costs of capital.
