A revealed preference approach to approximate utility maximisation<\/a><\/strong> (2025): Journal of Economic Theory<\/em>, 228.<\/p>\n\n\n\n

Summary<\/strong>. Nobody believes in the model of utility maximisation, but we do believe that it is a good approximation of how consumers make their decisions. I provide a comprehensive method for eliciting preferences when the individuals are ‘almost’ utility maximising. <\/em><\/p>\n\n\n\n

Revealed preference and revealed preference cycles: A survey<\/a><\/strong> (2024): Journal of Mathematical Economics<\/em>, 113, with Josh Lanier and John Quah.<\/p>\n\n\n\n

Summary<\/strong>. We discuss the importance of acyclicity conditions in the revealed preference literature. (Upon an invitation to the 50th anniversary issue of Journal of Mathematical Economics.)<\/em><\/p>\n\n\n\n

Comparative statics with linear objectives: normal demand, monotone marginal costs, and ranking multi-prior beliefs<\/a><\/strong> (2024): Econometrica<\/em>, 92 (1), pp 167-200, with John Quah.<\/p>\n\n\n\n

Summary.<\/strong> Consider an optimisation problem with a linear objective. What is the necessary and sufficient condition under which the set of minimisers increases in a natural sense? We show that it is all about parallelograms<\/em>. We apply our results to normal demand, monotone marginal costs, and comparative statics in models of ambiguity.

Revealed statistical consumer theory<\/a><\/strong> (2024): Economic Theory<\/em>, 77, pp 823\u2013847, with Roy Allen and John Rehbeck.<\/p>\n\n\n\n

Summary.<\/strong> What if individuals care about a distribution of consumption, rather than consumption bundles? We characterise such a behaviour and show that it is equivalent to a model in which the consumer cares only about a statistic of the distribution.<\/p>\n\n\n\n

Making sense of the monkey business: Re-examining tests of animal rationality<\/a><\/strong> (2022): Journal of Economic Behavior & Organization<\/em>, 196, pp 220-228, with Roy Allen and John Rehbeck.<\/p>\n\n\n\n

Summary.<\/strong> We discuss how to perform revealed preference tests on non-human animals. Spoiler: They do much better than human animals!<\/p>\n\n\n\n

Markov distributional equilibrium dynamics in games with complementarities and no aggregate risk<\/a><\/strong> (2022): Theoretical Economics<\/em>, 17, pp 725-762, with \u0141ukasz Balbus, Kevin Reffett, and \u0141ukasz Wo\u017any.<\/p>\n\n\n\n

Summary.<\/strong> Nine years in the making, but it\u2019s finally here! If you want to know how to analyse and compute equilibrium transitional dynamics in games\/economies with infinitely many agents and private shocks\u2026 search no more. This paper contains everything you need.<\/p>\n\n\n\n

Just-noticeable difference as a behavioural foundation of the critical cost-efficiency index<\/a><\/strong> (2020): Journal of Economic Theory<\/em>, 188.<\/p>\n\n\n\n

Summary.<\/strong> Were you using Afriat’s efficiency index (CCEI) but didn’t know what was its behavioural interpretation? I show that it measures the inability to differentiate between alternatives. Now you know!<\/p>\n\n\n\n

\n\n\n\n

A qualitative theory of large games with strategic complementarities<\/a><\/strong> (2019): Economic Theory<\/em>, 67, pp 497\u2013523, with \u0141ukasz Balbus, Kevin Reffett, and \u0141ukasz Wo\u017any.<\/p>\n\n\n\n

Summary.<\/strong> We show how to compute equilibria and determine comparative statics in games with a continuum of players and strategic complementarities. Particularly useful when studying interactions in which payoffs of players are affected by the whole distribution of actions, rather than its aggregate.<\/p>\n\n\n\n

\n\n\n\n

Revealed time preference<\/a><\/strong> (2018): Games & Economic Behavior<\/em>, 112, pp 67-77.<\/p>\n\n\n\n

Summary.<\/strong> How to tell if someone is a discounted utility maximiser? I show how to do it when you observe a finite number of binary choices over delayed rewards. Spoiler: Often anything goes!<\/p>\n\n\n\n

Efficiency of competitive equilibria in economies with time-dependent preferences<\/a><\/strong> (2015): Journal of Economic Theory<\/em>, 159, pp 311-325. <\/p>\n\n\n\n

Summary.<\/strong> In exchange economies where preferences of consumers change over time, competitive equilibria are efficient in a rather strong sense. <\/p>\n\n\n\n

Differential information in large games with strategic complementarities<\/a><\/strong> (2015), Economic Theory<\/em>, 59(1), pp 201-243, with \u0141ukasz Balbus, Kevin Reffett, and \u0141ukasz Wo\u017any.<\/p>\n\n\n\n

Summary.<\/strong> A follow up to the 2019 paper (although this one was published first). Now you can solve and determine comparative statics in games with a continuum of agents and strategic complementarities, when the information individuals have about the game varies.<\/p>\n\n\n\n
