My academic interests revolve around a variety of topics in Microeconomic Theory, inlcuding revealed preference theory, monotne comparative statics, theory of large games, and general equilibrium. Below you can find my publications and working papers.

We investigate a model of deterministic stochastic choice for the standard consumer problem. We introduce the framework of statistical consumer theory where the individual maximizes their utility with respect to a distribution of bundles that is constrained by a statistic (e.g. mean expenditure). We show that this behavior is observationally equivalent to an individual whose preferences depend only on the statistic of the distribution. Statistical consumer theory neither nests nor is nested in the random utility approach. We provide a formal statistical test of the model accounting for sampling variability and demonstrate it in an illustrative example using data on capuchin monkeys. (This version: October 2019)
Critical cost-efficiency index (or CCEI), proposed in Afriat (1973) and Varian (1990), is one of the most commonly used measures of departures from rationality. Roughly speaking, it evaluates the level of tolerance for wasted expenditure that is required for choices of an individual to be rationalisable with utility maximisation. We show that this index is equivalent to a particular notion of the just-noticeable difference, that is, a measure of dissimilarity between alternatives that is sufficient for the agent to tell them apart. Therefore, we argue that CCEI evaluates the consumer’s cognitive inability to discriminate among options. (R&R at
Journal of Economic Theory. This version: February 2019)Economic decisions often involve maximising an objective whose value is itself the outcome of another optimisation problem. This decision structure arises in multi-output production and choice under uncertainty with multi-prior beliefs. To analyse comparative statics in these models, we introduce a theory of Supermodular correspondences. In particular, we employ this theory to generalise the notion of first order stochastic dominance to multi-prior beliefs, allowing us to characterise conditions under which greater optimism leads to higher action. (This version: February 2019)
Previous title: "Supermodular value functions and supermodular correspondences"The evidence from psychophysics suggest that people are unable to discriminate between alternatives unless the options are significantly different. We provide a method of eliciting consumer preference from observable choices when the agent is incapable of discerning between similar bundles. (This version: June 2017)

What conditions on the set of observations are necessary and sufficient for it to be consistent with a firm choosing inputs to maximize profit, subject to a production function exhibiting production complementarities? In this paper, we develop an axiomatic characterisation of this hypothesis. (This version: September 2014)
