the paper deals with kant's conception of moral judgment. i start by criticizing a dominant interpretation of kant's practical rationality in its assertion that choosing, i.e. exercising judgment consists in adopting a maxim; and adopting a maxim is equivalent to acting on a principle, giving oneself the moral law (korsgaard). according to this view, the logical inescapability of choo...

Polarizing discussions on political and social issues are common in mass and user-generated media. However, computer-based understanding of ideological discourse has been considered too difficult to undertake. In this paper we propose a statistical model for ideology discourse. By ideology we mean “a set of general beliefs socially shared by a group of people.” For example, Democratic and Repub...

The phenomenon of infrequent price changes has troubled economists for decades. Intuitively one feels that for most price-setters there exists a range of inaction, i.e. a substantial measure of the states of the world, within which they do not wish to modify prevailing prices. However, basic economics tells us that when marginal costs change it is rational to change prices, too. Economists wish...

Contrarily, rather than the action-based focus on rules governing action, the agent-based approach concerns the fundamental character and motivations of the individual agent. Under the agent-based approach, moral behavior is not limited to adherence to a rule or guideline but rather involves the individual rationally pursuing moral excellence as a goal in and of itself. In essence, ethics becom...

Recent literature shows that learning in oligopoly games might in the long run result in the Cournot or in the Walras equilibrium. Which outcome is achieved seems to depend on the underlying learning dynamics. This paper analyzes the forces behind the learning mechanisms determining the long run outcome. Apart from the fact that there is a difference between social and individual learning, the ...

We show how solution concepts in games such as Nash equilibrium, correlated equilibrium, rationalizability, and sequential equilibrium can be given a uniform definition in terms of knowledge-based programs. Intuitively, all solution concepts are implementations of two knowledge-based programs, one appropriate for games represented in normal form, the other for games represented in extensive for...
