Floor versus Screen Trading : Evidence from the German Stock Market

Abstract: The last decade has witnessed a dramatic increase in both the number and the market share of screen-based trading systems. Electronic trading systems do offer lower operating costs and the possiblilty of remote access to the market. On the other hand, arguments based on the anonymity of electronic trading systems suggest that adverse selection may be a more severe problem and that, therefore, bid-ask spreads may be higher. The present paper addresses the issue of transaction costs in floor and computerized trading systems empirically. In Germany, floor and screen trading for the same stocks exist in parallel. Both markets are liquid and operate simultaneously for several hours each day. An analysis of the bid-ask spreads reveals that the electronic trading system is relatively less attractive for less liquid stocks. The market shares of the competing systems reveal a similar pattern. The market share of the electronic trading system is negatively related to the total trading volume of the stock, is positively related to the difference between spreads on the floor and in the screen trading system and is at least partially negatively related to return volatility. We further document that spreads in the electronic trading system respond more heavily to changes in return volatility and that the adverse selection component of the spread is larger. We discuss implications our results have for the design of electronic trading systems.

Cash Savings and Stock Price Informativeness

Abstract: This paper shows that managers use the information they learn from the stock market when they decide on corporate cash savings. In particular, corporate savings are much more sensitive to stock price when the price contains more information that is new to managers. Moreover, the significant effect of stock price informativeness on the savings-to-price sensitivity is not due to market mispricings and remains even after controlling for various sources of public and managerial private information. Overall, the results highlight a new channel through which the stock market affects corporate decisions, which suggests that the stock market is not a sideshow.

Assembling international development: Accountability and the disarticulation of a social movement

Abstract: This paper examines how international development funding and accountability requirements are implicated in the so-called disarticulation of a social movement. Based on field studies in Guatemala and El Salvador, we show and explain the way accountability requirements, which encompass management and accounting, legal, and financial technologies, constitute the field of international development through the regulation of heterogeneous social movement organizations. We highlight how accountability enables a form of governance that makes possible the emergence of entities (with specific attributes), while restricting others. Our analysis has implications for governmentality studies that have examined the interrelation of assemblages by analyzing how these interrelations are operationalized at the field level through the Deleuze-and-Guattari-inspired processes of territorialization, coding, and overcoding.
