The gender wage gap in top corporate jobs is still there
We investigate the gender wage gap in top corporate jobs for the years 2000 till 2004. Using data from the OSIRIS database, we ¯nd that female managers receive 24.0 percent less in total compensation (salary, bonuses, other payments and exer- cised stock options) than their male colleagues. When we control for personal, ¯rm and industry characteristics, this di®erence reduces to 15.9 percent. Controlling for occupational segregation, i.e. \glass ceiling", reduces the di®erence to 6.0 percent. Additional results that fully consider the role of stock option indicate a 9.0 to 12.1 percent di®erence. These results suggest that the main sources of the gender wage gap in top corporate jobs are occupational segregation and a di®erent endowment of male and female managers with stock options.
How Effective is European Merger Control?
This paper applies a novel methodology to a unique dataset of large concentrations during the period 1990-2002 to assess merger control’s effectiveness. By using data gathered from several sources and employing different evaluation techniques, we analyze the economic effects of the European Commission’s (EC) merger control decisions and distinguish between blockings, clearances with commitments (either behavioral or structural), and outright clearances. We run an event study on merging and rival firms’ stocks to quantify the profitability effects of mergers and merger control decisions. We back up our results and methodology by using alternative measures for the merger’s profitability effects based on balance sheet data and obtain consistent results. Our findings suggest that outright blockings solve the competitive problems generated by the merger. Remedies are not always effective in solving the market power concerns, at least not on average. Nevertheless, both structural (divestitures) and behavioral remedies do help restore effective competition when correctly applied to anticompetitive mergers during the first investigation phase. Yet, they are on the whole ineffective or even detrimental when applied after the second investigation phase. Finally, remedies - especially behavioral ones - seem to constitute a rent transfer from merging firms to rivals when mistakenly applied to pro-competitive mergers
EU Merger Remedies: A Preliminary Empirical Assessment
Mergers that substantially lessen competition are challenged by antitrust authorities. Instead of blocking anticompetitive transitions straight away, authorities might choose to negotiate with the merging parties and allow the transactions to proceed with modifications that restore or preserve the competition in the involved markets. We study a sample of 167 mergers that were under the European Commission’s scrutiny from 1990 to 2002. We use an event study methodology to identify the potential anticompetitive effects of mergers as well as the remedial provisions on these transactions. Stock market reactions around the day of the merger’s announcement provide information on the first question, whereas the stock market reactions around the commission’s final decision day convey information about the outcome of the bargaining process between the authority and the merging parties. We first classify mergers according to their effects on competition and then we develop hypotheses on the effects that remedies are supposed to achieve depending on the merger’s competitive outcome. We isolate several stylized facts. First, we find that remedies were not always appropriately imposed. Second, the market seems to be able to predict remedies’ effectiveness when applied in phase I. Third, the market also seems able to produce a good prior to phase II’s clearances and prohibitions, but not to remedies. This can be due either to a measurement problem or related to the increased merging firms’ bargaining power during the second phase of the merger review
Rating based indexing of Istanbul Stock Exchange, lessons from its failure and Novo Mercado's sucess in to advance corporate governance reforms
This paper compares the objectives, processes and outcomes of different approaches adopted by BOVESPA and ISE for differentiating “better governed” firms listed on their respective boards. Novo Mercado of BOVESPA, launched at the end of December 2000, was able to attract over 30 companies within 5 years, whereas ISE CG Index, announced in February 2005, is not yet launched due to lack of interest from the issuers
How effective is European merger control?
This paper applies an intuitive approach based on stock market data to a unique dataset of large concentrations during the period 1990-2002 to assess the effectiveness of European merger control. The basic idea is to relate announcement and decision abnormal returns. Under a set of four maintained assumptions, merger control might be interpreted to be effective if rents accruing due to the increased market power observed around the merger announcement are reversed by the antitrust decision, i.e. if there is a negative relation between announcement and decision abnormal returns. To clearly identify the events' competitive effects, we explicitly control for the market expectation about the outcome of the merger control procedure and run several robustness checks to assess the role of our maintained assumptions. We find that only outright prohibitions completely reverse the rents measured around a merger's announcement. On average, remedies seem to be only partially capable of reverting announcement abnormal returns. Yet they seem to be more effective when applied during the first rather than the second investigation phase and in subsamples where our assumptions are more likely to hold. Moreover, the European Commission appears to learn over time. --Merger Control,Remedies,European Commission,Event Studies
Is the Event Study Methodology Useful for Merger Analysis? A Comparison of Stock Market and Accounting Data
Using a sample of 167 mergers during the period 1990-2002 involving 544 firms either as merging firms or competitors, we contrast a measure of the merger’s profitability based on event studies with one based on accounting data. We find positive and significant correlations between them when using a long window around the announcement date and, for rivals, in case of anticompetitive mergers

Synthesis report: Third International Conference on Corporate Governance in Emerging Market
The Third International Conference on Corporate Governance in Emerging Markets is one in a series of academic events organized by the Emerging Markets Corporate Governance Network (EMCGN). The Global Corporate Governance Forum at IFC endorses and supports the Network, which was first convened by Professor Stijn Claessens in 2001. The biannual academic conferences organized by the Network feature themes that are important to academics and practitioners interested in the role and effect of corporate governance in emerging markets.This report summarizes 10 thematically different sessions that explored important topical areas in corporate governance research
Marginal Q, Tomin´s Q, Cash Flow and Investment
Many studies of the determinants of investment use Tobin’s T to control for the investment opportunities of a firm. Tobin’s T roughly measures the average return on a firm’s capital anticipated by the market. More relevant for investment decisions, however, is the marginal return on capital. In this paper we estimate investment and R&D equations using a measure of marginal T. We use marginal q to identify the existence of cash constraints and managerial discretion, and as a separate explanatory variable. For a sample of 562 U.S. firms observed over the 1977-1996 period we present evidence confirming the existence of both cash constraints in some companies and managerial discretion in others.
