Monetary Policy under Behavioral Expectations: Theory and Experiment
Matthias Weber (University of Amsterdam)
Expectations play a crucial role in modern macroeconomic models. We replace the common assumption of rational expectations in a New Keynesian framework by the assumption that expectations are formed according to a heuristics switching model that has performed well in earlier experiments. We show how the economy behaves under these assumptions with a special focus on inflation volatility. Then we derive implications for monetary policy. We compare the results of the behavioral model to the results arising from full rationality and conduct a learning to forecast experiment to test the opposing theoretical predictions in the laboratory.

Valuing Malaria Morbidity: Results from a Global Meta-Analysis
Mehmet Kutluay (VU University Amsterdam)
The risk of malaria transmission worldwide is expected to increase with climate change. This makes it important, from an economics perspective, to focus on the costs of illness and the benefits of avoiding malaria. To this end, we analyze the factors that explain willingness to pay (WTP) to avoid malaria morbidity by summarizing the valuation literature via a meta-analysis. A previous meta-analysis on malaria is improved by extending the database, introducing new explanatory variables and using more sophisticated analytical tools. These analytical tools include comparing multiple regression models via a cross-validation exercise, to quantify best fit. These regressions show that revealed preferences, as opposed to stated preferences, significantly lowers mean WTP values. No significant differences are detected for policies that either prevent (pre-morbidity) or treat malaria (post-morbidity). We add two new results to the morbidity literature. 1) Age has a non-linear impact on mean WTP (increasing between 33 and 54 year-olds) and 2) WTP decreases if malaria policies target com- munities instead of individual households. These results provide policy-makers with important information on the dynamics behind the benefits of malaria interventions.
