Project: Feedback Design and Preference Elicitation: Field Experiments in Digital Economics

Description: This thesis aims to contribute to this discussion with four eld experiments that explore the potential of digital technology in improving the outcomes of workers, students, and consumers. The first two experiments focus on the workplace. Productivity data from a new monitoring technology are used to detect worker-level areas of improvement, to tailor feedback, and to evaluate the impact of the feedback programs. The third experiment is in education. A digital learning platform is developed to measure student effort and to target this effort directly as a means to improve learning outcomes. The final experiment uses a communication technology in a natural field setting with many consumers to implement an incentive-compatible experimental method that elicits individual risk attitudes repeatedly.

Project: Understanding Retail Gasoline Pricing: An Empirical Approach

Description: The thesis is about competition between retailers. The first project uses a large data set comprising daily retail gasoline prices in the Netherlands. We consider the emergence of lower-cost unmanned gasoline retailers and how this changed competition in the period 2005-2011. Our main finding is that the lower costs have a direct negative effect on the prices at the transformed stations as well as a lower spillover effects on the nearby competitors. In the second project, we provide a theoretical argument for show why lower-priced retailers have an incentive to announce discounts off a reference price that reveal the underlying cost level to consumers. Then we give a theoretical explanation for the regular, weekly additional (bonus) discounts that we observe in the Dutch retail gasoline market. In a short companion paper, we discuss the empirical relevance of the widely accepted stopping rule in search with rational consumers and recall. We provide experimental evidence that shows that in price search, subjects exhibit behavior consistent risk- or loss-averse risk-attitudes. In the final paper we employ an hourly-price dataset to show that retail prices react quicker to the positive changes in the retail-price recommendations. Using real-time traffic data, we reject the hypothesis that hourly fluctuations in consumer demand explains the observed price changes.
