The purpose of this paper is to cast a new light on the post-Sombartian debate. It contributes to some understanding of the birth of the concept of capitalism itself. The author argues that the history of how the concept of capitalism was invented is an example of the influence of accounting...

In this paper, the authors show that capitalism and double-entry bookkeeping are not indissociably interconnected as Sombart argued in his book in 1916. Indeed, the double-entry bookkeeping accounting system was also adopted by anti-capitalist countries where a new economic system was set up. A...

We study stochastic games with incomplete information on one side, where the transition is controlled by one of the players. <p> We prove that if the informed player also controls the transition, the game has a value, whereas if the uninformed player controls the transition, the max-min value, as...</p>

We study zero-sum stochastic games in which players do not observe the actions of the opponent. Rather, they observe a stochastic signal that may depend on the state, and on the pair of actions chosen by the players. We assume each player observes the state and his own action. <p> We propose a...</p>

We survey recent results on the existence of the value in zero-sum stopping games with discrete and continuous time, and on the existence of e-equilibria in non zero-sum games with discrete time.

This paper finds that the market betas of value and small stocks have decreased by about 75% in the second half of the twentieth century. The decline in beta can be related to a long-term improvement in economic conditions that made these companies less risky.
