Expectations are central to models of economic and financial decision-making. Yet in practice, individuals are often inattentive and, when asked, report fragile, context-dependent expectations that are only weakly linked to decisions. This raises the question to what extent they hold such...

Revealed preference theory (RPT) and its behavioral extension (BRPT) underpin an important strand of welfare economics. Their normative appeal rests on the claim that welfare can be inferred from observed behavior without substantive assumptions about what agents should value - a property I call...

Background: Despite advances in monitoring and forecasting systems, natural disasters continue to cause significant human losses. During the response phase, fast decisions are required to allocate limited resources, particularly rescue helicopters, which play a key role in reaching inaccessible...

This paper develops an axiomatic framework for decision making when preferences depend not only on the current alternative but also on the past frequency with which alternatives have been chosen. We identify key independence axioms that characterize frequency-dependent preferences. In addition,...

We study the ambiguity-adjusted return distribution induced by an investor with smooth ambiguity preferences 'a la Klibano! et al. (2005), who faces uncertainty about the variance of asset returns. The variance uncertainty is modeled using a gamma distribution, a second-order prior over the...

We propose and axiomatize a new model of incomplete preferences under uncertainty, which we call hope-and-prepare preferences. An act is considered more desirable than another when, and only when, both an optimistic evaluation, computed as the welfare level attained in a best-case scenario, and...

Understanding when and why nudges work is crucial for designing interventions that consistently and reliably change behaviour. This paper explores the relationship between decision-making speed and the effectiveness of two nudges – carbon footprint labelling and menu repositioning – aimed at...

We present a theory of context-dependent risk preferences under which within-state payoff comparisons and regret aversion shape decisions. Defining the attraction and compromise effect in reference to a state-space-based description of the choice problem, we show that our theory can account for...

Promoting household-level adaptation measures is an important part of climate change adaptation policies to reduce vulnerability to droughts for (agro-)pastoral communities in sub-Saharan Africa. To develop effective supportive policies, it is important to get a better understanding of the needs...

Information unraveling is an elegant theoretical argument suggesting that private information is voluntarily and fully revealed in many circumstances. However, the experimental literature has documented many cases of incomplete unraveling and has suggested limited depth of reasoning on the part...

Comonotonicity (''same variation'') of random variables minimizes hedging possibilities and has been widely used, e.g., in Gilboa and Schmeidler's ambiguity models. This paper investigates anticomonotonicity (''opposite variation''; abbreviated ''AC''), the natural counterpart to comonotonicity....

Several behavioral models assume that choice over multi-attribute goods is systematically affected by the ranges of attribute values. Two recurring principles in this literature are contrast, whereby attributes with larger ranges attract attention and are therefore overweighted, and...
