This paper analyzes mean reversion in international stock markets during the period 1900-2008, using annual data. Our panel of stock indexes in seventeen developed countries, covering a time span of more than a century, allows us to analyze in detail the dynamics of the mean-reversion process....

This paper analyzes mean reversion in the stock markets of 18 OECD countries during the years 1900–2009. In this period it takes stock prices about 18.5 years, on average, to absorb half of a shock. However, using a rolling-window approach we establish large fluctuations in the speed of mean...

This paper is the first detailed and world-wide investigation of the developments in banking competition during the past fifteen years. Using the Panzar-Rosse approach, we establish significant changes over time in the competitiveness of the banking industry. The changes in competition over time...

This paper demonstrates that the level of competition in the existing Panzar Rosse (P-R) literature is systematically overestimated and that the tests on both monopoly and perfect competition are distorted. This is due to the use of bank revenues divided by total assets as dependent variable in...

Often, a relatively small group of trades causes the major part of the trading costs on an investment portfolio. For the equity trades studied in this paper, executed by the world's second largest pension fund, we find that only 10% of the trades determines 75% of total market impact costs....

This article applies quantile regression to assess the factors that influence the risk of incurring high trading costs. Using data on the equity trades of the world's second largest pension fund in the first quarter of 2002, we show that trade timing, momentum, volatility and the type of broker...

The Panzar-Rosse test has been widely applied to assess competitive conduct, often in specifications controlling for firm scale or using a price equation. We show that neither a price equation nor a scaled revenue function yields a valid measure for competitive conduct. Moreover, even an...

This paper discusses the implications of mean reversion in stock prices for long-term investors such as pension funds. We start with a general definition of a mean-reverting price process and explain how mean reversion in stock prices is related to mean reversion in stock returns. Subsequently,...

This paper is the first to analyze the price effects of equity trading by a pension fund. We find that, on average, these effects are nonðnegligible: 20 basis points for buys and 26 basis points for sells. Furðthermore, we show that (relative) trade size and market capitalization, commonly...
