Our society can benefit immensely from algorithmic decision-making and similar types of artificial intelligence. But algorithmic decision-making can also have discriminatory effects. This paper examines that problem, using online price differentiation as an example of algorithmic...

This chapter reviews the theory of the voluntary public and private redistribution of wealth elaborated by economic analysis in the last forty years or so. The central object of the theory is altruistic gift-giving, construed as benevolent voluntary redistribution of income or wealth. The theory...

This paper characterizes the out-of-equilibrium dynamics of a symmetric, pure exchange economy with two goods and N agents with uniformly distributed preferences and identical endowments. Relaxing the auctioneer assumption, but maintaining a global price rule, sequentially random pairwise...

Some fear that personalised communication can lead to information cocoons or filter bubbles. For instance, a personalised news website could give more prominence to conservative or liberal media items, based on the (assumed) political interests of the user. As a result, users may encounter only...

This paper discusses the troubled relationship between contemporary advertising technology (adtech) systems, in particular systems of real-time bidding (RTB, also known as programmatic advertising) underpinning much behavioural targeting on the web and through mobile applications. This paper...

We characterize a measure of social welfare for linear production economies in which individuals differ in productive skills and preferences. The key feature of our measure is that it aggregates fairness gaps, defined as the difference between the money-metric utility that the individual...

This paper develops and defends a new approach to belief aggregation, involving confidence in beliefs. It is characterised by a variant of the Pareto condition that enjoins respecting consensuses borne of compromise. Confidence aggregation recoups standard probability aggregation rules, such as...

We study risk taking on behalf of others in an experiment on a large random sample. The decision makers in our experiment are facing high-powered incentives to increase the risk on behalf of others through hedged compensation contracts or with tournament incentives. Compared to a baseline...

We estimate responsibility-sensitive welfare weights for health that facilitate inequalityand inequity-sensitive policy evaluation. In a UK general population sample, 569 online experiment participants distribute constrained resources to determine the health of hypothetical individuals...
