Though more than 100 countries have adopted gender quotas, the impacts of these reforms on women’s political leadership remain largely unknown. We exploit a quasi-experiment – a zipper quota imposed by the Swedish Social Democratic national party on municipal party groups – to examine...

Anticompetitive mergers increase competitors' profits, since they reduce competition. Using a model of endogenous mergers, we show that such mergers nevertheless may reduce the competitors' share-prices. Thus, event-studies can not detect anti-competitive mergers.

There is diverging empirical evidence on the competitive effects of horizontal mergers: consumer prices (and thus presumably competitors' profits) often rise while competitors' share prices fall. Our model of endogenous mergers provides a possible reconciliation. It is demonstrated that...

Most econometric studies of equity market integration suggest that national markets are increasingly becoming part of a global equity market. As regards the extent of this integration, however, the results are often inconclusive. Further analysis calls for a closer scrutiny of the basic...

This paper makes use of individual data for 2004 to 2008 on owners of closely-held businesses in Sweden to estimate the role of both tax and non-tax determinants in the choice to be a closely-held corporation vs. a proprietorship. While lower-income individuals face relatively neutral...

The major strand of finance literature understands market efficiency through the market’s ability to process information into prices. Another strand of literature refers to the economists’ usual sense of the word, i.e. that markets ensure that resources are allocated to their most profitable...

This paper estimates the role of both tax and non-tax determinants in the choice in Sweden to be a closely-held corporation vs. a proprietorship, using individual data for 2004 to 2008 on owners of closely-held businesses. While lower-income individuals face relatively neutral incentives, higher...
