In the context of a continuum of random variables, arising, for example, as rates of return in financial markets with a continuum of assets, or as individual responses in games with a continuum of players, an important economic issue is to show how idiosyncratic risk can be removed through some...

We study a simultaneous, complete-information game played by p = 1 P agents. Each p has an ordinal decision variable Y p ∈ A p ={ 0 1 M p} , where M p can be unbounded, A p is p’s action space, and each element in A p is an action , that is, a potential value for Y p . The collective action...

We design a laboratory experiment to identify whether a preference for randomization defines a stable type across different choice environments. In games and individual decisions, subjects face twenty simultaneous repetitions of the same choice. Subjects can randomize by making different choices...
