Incentivized experiments in which individuals receive monetary rewards according to the outcomes of their decisions are regarded as the gold standard for preference elicitation in experimental economics. These task-related real payments are considered necessary to reveal subjects' "true preferences". Using a systematic, large-sample approach with three subject pools of private investors, professional investors, and students, we test the effect of task-related monetary incentives on risk preferences elicited in four standard experimental tasks. We find no systematic differences in behavior between subjects in the incentivized and non-incentivized regimes. We discuss implications for academic research and for applications in the field.

We examine the effect of personal, two-way communication on the behavior of borrowers, who have fallen behind on their consumer loan payments. While the lender has informed all borrowers about the delinquency through an automatically generated letter, some borrowers also receive a phone call from a randomly assigned bank agent. We find that borrowers, who speak with a bank agent typically for only a few minutes, are significantly more likely to make timely payments and significantly less likely to default. This finding holds in a subset of hard-to-reach borrowers as well as when we instrument for the call with exogenous variation in borrowers' reachability. The effect of the call is also persistent. Borrowers, who receive a call, are significantly less likely to become delinquent again. Personal aspects of the call, such as the likeability of the agent's voice, significantly affect payment behavior, while the surprise element of the call does not. Our results suggest that the form of communication significantly affects borrowers' payment behavior.

We analyze the long-term effects of living under communism and its anticapitalist doctrine on households' financial investment decisions and attitudes towards financial markets. Utilizing comprehensive German brokerage data and bank data, we show that, decades after Reunification, East Germans still invest significantly less in the stock market than West Germans. Consistent with communist friends-and-foes propaganda, East Germans are more likely to hold stocks of companies from communist countries (China, Russia, Vietnam) and of state-owned companies, and are unlikely to invest in American companies and the financial industry. Effects are stronger for individuals exposed to positive "emotional tagging,” e.g., those living in celebrated showcase cities. Effects reverse for individuals with negative experiences, e.g., environmental pollution, religious oppression, or lack of (Western) TV entertainment. Election years trigger further divergence of East and West Germans. We provide evidence of negative welfare consequences due to less diversified portfolios, higher-fee products, and lower risk-adjusted returns.

Attitudes towards capital markets and stock-market investment still differ widely between Western and formerly communist countries, but there is also significant heterogeneity within the East. We argue that the speed of convergence is predicted by the quality of life-time experiences under communism. Utilizing novel German brokerage and bank data we document that, decades after Reunification, East Germans invest significantly less in stocks and hold more negative views on capital markets if they had unrelated positive experiences, e.g., from Olympic games or living in celebrated showcase cities. Results reverse for East Germans with negative experiences, like environmental pollution and religious oppression.

We experimentally study how presentation formats for return distributions affect investors' diversification choices. We find that sampling returns alleviates correlationneglect and constitutes an effective way to improve financial decisions. When participants get a description of probabilities for outcomes of the joint return distribution, we confirm the common finding that investors neglect the correlation between assets in their diversification choices. However, when participants sample from the joint distribution, they incorporate correlation into choices as predicted by normative theory. Results are robust across three experiments with varying expertise and experience of participants (students vs. investors), and varying return distributions (discrete, continuous).

Financial literacy affects wealth accumulation, and pension planning plays a key role in this relationship. In a large field experiment, we employ a digital pension aggregation tool to confront a treatment group with a simplified overview of their current pension claims across all pillars of the pension system. We combine survey and administrative bank data to measure the effects on actual saving behavior. Access to the tool decreases pension uncertainty for treated individuals. Average savings increase|especially for the financially less literate. We conclude that simplification of pension information can potentially reduce disparities in pension planning and savings behavior.
