This paper uses stochastic simulations on calibrated models to assess the optimal degree of reliance on fun ded pensions and on a particular type of unfunded (PAYG) pension. Surprisingly little is known about the optimal split between funded and unfunded systems when there are sources of...

Conventional wisdom in economics holds that traditional credit and insurance networks are inapt for insuring against covariate risks such as natural hazards. We challenge this claim by examining changes in financial allocations in Rotating Savings and Credit Associations (Roscas), a popular...

We consider the psychological and social foundations of human contributions and punishments in a voluntary contributions mechanism with punishment (VCMP). We eliminate 'dynamic economic linkages' between the two stages of our "modified" VCMP to rule out other potential explanations. We use a...

We consider income-source-dependent tax evasion and show that this is a generalization of the well-known endowment effect. We show that loss aversion, moral costs, mental accounting, and risk preferences play a key role in explaining key features of source-dependent tax evasion. We provide...

This paper studies how litigation and settlement behavior is affected by agents motivated by spiteful preferences under the American and the English fee-shifting rule. We conduct an experiment and find that litigation expenditures and settlement requests are higher for more spiteful...

Whether trade can achieve societal change is a contested topic and difficult to investigate. This round-up aims at summarizing recent empirical research on this topic while focusing on democracy and democratization as an important part of societal change. No robust results for change arising...

A group of decision makers simultaneously make contributions towards a green fund that reduces the future probability of a climate catastrophe. We derive the theoretical predictions of the effects on contributions arising from 'behavioral parameters' such as loss aversion and present-bias;...

I document a new fact about mobility within the United States. County-to-county migration and commuting drop discretely at state borders. People are three times as likely to move to a county 15 miles away, but in the same state, than to an equally-distant county across state lines. Standard...

Round numbers affect behavior in various domains, e.g., as prominent thresholds or focal points in bargaining. In line with earlier findings, residential real estate transactions in Germany cluster at round-number prices, but there are also interesting (presumably cultural) differences. We...

This study identifies day-of-the-week effects in business surveys using monthly data from the ifo Institute. The odds are higher that companies are more likely to exhibit more pessimistic business expectations for the upcoming months on Mondays and more optimistic expectations at the end of the...
