The theoretical literature on (non-random) choice largely follows the route of Richter (1966) by working in abstract environments and by stipulating that we see all choices of an agent from a given feasible set.  On the other hand, empirical work on consumption choice using revealed preference...

Let X be a compact, or path-connected, metric space whose topological dimension is at least 2. We show that there does not exist a continuous choice function (i.e., single-valued choice correspondence) defined on the collection of all finite feasible sets in X. Not to be void of content,...

We carry out a revealed preference analysis of monotone comparative statics. We ask what restrictions on an agent's observed choice behavior are necessary and sufficient to rationalize the data with a preference guaranteeing that choices are always monotone with re- spect to a parameter. We...

How do discount rates affect agents’ decisions and valuations? This paper provides a general method to analyze this question, allowing stochastic and managed cash flows, stochastic discount rates, and time inconsistency and including arbitrary learning and payoff or utility processes. We show...
