This study shows that individuals' habits in grocery shopping are incrementally useful in predicting their credit card payment behaviors and that such incremental predictive power can translate into incremental profits for firms. Guided by prior work, we identify five broad grocery shopping...

This paper examines how a negative shock to the security of personal finances due to severe identity theft changes consumer credit behavior. Using a unique data set of consumer credit records and alerts indicating identity theft and the exogenous timing of victimization, we show that the...

This research note empirically investigates whether cash can prevent consumers from making needless purchases in unexpected shopping situations. Cash can have a disciplinary effect on short-term consumption because it imposes a strong temporary budget constraint and also reinforces the pain of...

We provide the first economic research on `buy now, pay later' (BNPL): an unregulated FinTech credit product enabling consumers to defer payments interest-free into instalments. In 2021 transactions by BNPL firms are charged to 19.5% of active credit cards in our UK data. Charging a 0% interest,...

Firms often offer a menu of contracts which vary by fee structures in order to differentiate among different types of consumers. Such contracts require that consumers make estimates of their own future behavior to choose among service contracts whose prices condition on usage. We study the...

We build a framework to understand the effects of regulatory interventions in credit markets, such as caps on interest rates and higher compliance costs for lenders. We focus on the credit card market, in which we observe U.S. consumers borrowing at high and very dispersed interest rates,...

Using a framework that distinguishes short-term consumer preferences, individual reflective preferences and political preferences, we discuss from a constitutional economics perspective whether individuals find it in their common constitutional interest to endow representatives and bureaucrats...

When a decision-maker's attention is limited, her decisions depend on what she focuses on. This gives interested parties an incentive to manipulate not only the substance of communication but also the decision-maker's attention allocation. This paper models such attention manipulation. In its...

Demographic changes, tight public budgets, and reduced generosity of occupational pension plans shift the responsibility for an adequate retirement provision towards the individual. Applying the theoretical perspectives of Behavioural Finance and New Institutionalism to the domain of retirement...

Despite intense price competition firms obfuscate product information when it is relatively costless to reveal, contrary to neoclassical predictions. This paper considers whether firms can profitably conceal (part of) their prices for a homogeneous product when consumers differ in their ability...
