The Covid-19 pandemic has been a shock to retail payment behaviour. How have the changes differed across countries? What do they imply for the future of cash and digital payments? We assemble a new “Future of Payments” database on retail payment behaviour for up to 95 countries over...

We study how precipitation has affected food consumer price inflation (CPI), using dynamic panel estimation of food CPI Phillips curves across countries for 34 OECD member and candidate economies from 1985 to 2010 augmented with climate variables. We allow for nonlinear effects of precipitation...

This paper analyzes sin goods consumption when individuals exhibit present-focused preferences. It considers three types of present focus: present-bias with varying degrees of naiveté, Gul-Pesendorfer preferences, and a dual-self approach. We investigate the incentives to deviate from healthy...

We study the spending response of first-time borrowers to an overdraft facility and elicit their preferences, beliefs, and motives through a FinTech application. Users increase their spending permanently, lower their savings rate, and reallocate spending from non-discretionary to discretionary...

Our novel approach to modeling monopolistic competition with heterogeneous consumers involves a space of characteristics of a differentiated good (consumers' ideal points), alike Hotelling (1929). Firms have heterogeneous costs à la Melitz (2003). In addition to price setting, each firm also...

Both theory and recent empirical evidence on nudging suggest that observability of behavior acts as an instrument for promoting (discouraging) pro-social (anti-social) behavior. We connect three streams of literature (nudging, social preferences, and social norms) to investigate the universality...

This paper is the first attempt towards directly testing the existence of status seeking behavior of the poor for a developing economy, India, with the help of a large dataset. The paper empirically validates status consciousness among the relatively poor for both rural and urban areas across...

This paper documents the importance of consumer taste in trade flows using Belgian firm-product customs data by destination. We identify consumer taste through the use of a control function approach and estimate it jointly with other demand parameters using a very flexible demand specification....

We examine whether shrouding surcharges or partitioning prices raises demand in online shopping where consumers have very low costs of cancelling an initiated purchase process. In a field experiment with more than 34,000 consumers, we find that consumers in the online shop of a large German...

In this paper, we use a unique dataset on switching between mobile handsets in a sample of about 8,623 subscribers using tariffs without handset subsidies from a single mobile operator on a monthly basis between July 2011 and December 2014. We estimate a discrete choice model in which we account...
