[To investigate the effect of taxation on stock price and trading volume around the ex-dividend day, we use the Italian stock market, where dividends on two classes of stock are taxed differently. We find that the weighted average of investors' tax rates is reflected in the ex-day prices and the variance of the relative tax rate across investors is reflected in the volume of trades. We also show that higher transaction costs result in higher ex-dividend day excess returns and lower abnormal volume. This finding is consistent with "profit elimination" activity by institutions and corporations.]

The higher taxation of dividends in the United States gave rise to theories that explain why companies pay dividends. Tax-based signaling models propose that the higher tax on dividends is a necessary condition to make them informative about companies' values. In Germany, where dividends are not tax-disadvantaged and in fact are taxed lower for most investor classes, these models predict that dividends are not informative. However, the authors find that the stock price reaction to dividend news in Germany is similar to that found in the United States. This suggests other reasons, beyond taxation, that make dividends informative.

We study the stock market valuation of mergers and acquisitions in the European banking industry. Based on a sample of very large deals observed from 1988 to 1997 we document that, on average, at the announcement time the size-adjusted combined performance of both the bidder and the target is statistically significant and economically relevant. Although our sample shows a great deal of cross-sectional variation, the general results are mainly driven by the significant positive abnormal returns associated with the announcement of domestic bank to bank deals and by product diversification of banks into insurance. On the contrary, we found that M&A with securities firms and concluded with foreign institutions did not gain a positive market's expectation. Our results are remarkably different from those reported for US bank mergers. We explain our different results as stemming from the different structure and regulation of EU banking markets, which are shown to be more similar between them than as compared with the US one.

We study a sample of the world’s largest financial conglomerates from 15 countries and we track their largest divestitures over the period 2005–2016. We develop a novel market-based metric to analyse the impact of divestitures on financial conglomerate excess value, and our findings point to divestitures having a significant impact on financial conglomerate valuation, contributing to a reduced conglomerate discount. Our results are driven by sales of financial service assets. Selling assets unrelated to the financial sector has no significant effect on conglomerate excess value. These results are robust with the inclusion of multiple control variables and alternative econometric model specifications. Altogether these results cast doubts on the existence of large benefits for financial conglomerates from combining financial service activities. This study has implications both for financial conglomerate boards who might direct their strategies to downsize their firms, and for regulators who address issues related to financial stability.
