We introduce random evolving lotteries to study preference for non‐instrumental information. Each period, the agent enjoys a flow payoff from holding a lottery that will resolve at the terminal date. We provide a representation theorem for non‐separable risk consumption preferences and use...

In a generic finite normal form game with 2(alpha) + 1 Nash equilibria, at least alpha of the equilibria are nondegenerate mixed strategy equilibria (that is, they involve randomization by some players).

We develop an extension of Luce's random choice model to study violations of the weak axiom of revealed preference. We introduce the notion of a stochastic preference and show that it implies the Luce model. Then, to address well‐known difficulties of the Luce model, we define the attribute...

We introduce a notion of coarse competitive equilibrium (CCE), to study households' inability to tailor their consumption to the state of the economy. Our notion is motivated by limited cognitive ability (in particular attention, memory, and complexity) and it maintains the complete market...

We analyse preferences over finite decision problems in order to model decision-makers with "changing tastes". we provide conditions on these preferences that identify the Strotz model of consistent planning. building on an example given by <xref ref-type="bibr" rid="R8">Peleg and Yaari (1973)</xref>, we show that for problems with...
