Diffusion or War? Foucault as a Reader of Tarde

The objective of this chapter is to clarify the social theory underlying in Foucault’s genealogy of power/knowledge thanks to a comparison with Tarde’s microsociology. Nietzsche is often identified as the direct (and unique) predecessor of this genealogy, and the habitual criticisms are worried about the intricate relations between Foucault and Marx. These perspectives omit to point to another – and more direct – antecedent of Foucault`s microphysics: the microsociology of Gabriel Tarde. Bio-power technologies must be read as Tardian inventions that, by propagation, have reconfigured pre-existing social spaces, building modern societies. We will see how the Tardean source in Foucault’s genealogy sheds new clarity about the micro-socio-logic involved in it, enabling us to identify some of its aporiae and to imagine some solutions in this respect as well

Insiders-outsiders, transparency and the value of the ticker

We consider a multi-period rational expectations model in which risk-averse investors differ in their information on past transaction prices (the ticker). Some investors (insiders) observe prices in real-time whereas other investors (outsiders) observe prices with a delay. As prices are informative about the asset payoff, insiders get a strictly larger expected utility than outsiders. Yet, information acquisition by one investor exerts a negative externality on other investors. Thus, investors’ average welfare is maximal when access to price information is rationed. We show that a market for price information can implement the fraction of insiders that maximizes investors’ average welfare. This market features a high price to curb excessive acquisition of ticker information. We also show that informational efficiency is greater when the dissemination of ticker information is broader and more timely

What Makes a Utopia Inconvenient? On the Advantages and Disadvantages of a Realist Orientation to Politics

Contemporary politics is often said to lack utopias. For prevailing understandings of the practical force of political theory, this looks like cause for celebration. As blueprints to apply to political practice, utopias invariably seem too strong or too weak. Through an immanent critique of political realism, I argue that utopian thought, and political theory generally, is better conceived as supplying an orientation to politics. Realists including Bernard Williams and Raymond Geuss explain how utopian programs like universal human rights poorly orient their adherents to politics, but the realists wrongly conclude that utopias and other ideal theories necessarily disorient us. As I show through an analysis of utopian claims made by Michel Foucault, Malcolm X, and John Rawls, utopias today can effectively disrupt entrenched forms of legitimation, foster new forms of political identity, and reveal new possibilities within existing institutions. Utopias are needed to understand the political choices we face today

Stock price informativeness, cross-listings and investment decisions

In this paper, the authors show that a cross-listing allows a firm to make better investment decisions because it enhances stock price informativeness.Cross-listings; cross-listings premium; price informativeness; investment decisions; flow-back; ownership.

Information sharing, liquidity and transaction costs in floor-based trading systems

We consider information sharing between traders("floor brokers") who possess different types of information, namely information on the payoff of a risky security or information on the volume of liquidity trading in this security. We interpret these traders as dual -capacity brokers on the floor of an exchange. We identify conditions under which the traders are better off sharing information. We also show that information sharing improves price discovery, reduces volatility and lowers expected trading costs. Information sharing can improve or impair the depth of the market, depending on the values of the parameters. Overall our analysis suggests that information sharing among floor brokers improves the performance of floor-based trading systems.market microstructure; floor-based trading systems; open outcry; information sharing; information sales

Linkage principle, Multi-dimensional Signals and Blind Auctions

We compare the seller’s expected revenue in a second price sealed bid auction for a single object in which bidders receive multidimensional signals. Bidders’ valuations for the object depend on their signals and a signal observed privately by the seller. We show in various examples that the seller can be better off not revealing publicly his signal. Hence the linkage principle does not necessarily hold when bidders receive multidimensional signals.Auction Theory; Linkage Principle; Multidimensional Signals; Blind Auctions
