We apply a novel crowdsourcing approach to provide rapid insights on the most promising interventions to promote uptake of COVID-19 booster vaccines. In the first stage, international experts proposed 46 unique interventions. To reduce noise and potential bias, in the second stage, experts and...

Peoples' willingness to vaccinate is critical to combating the COVID-19 pandemic. We devise a representative experiment to study how the design of the vaccine approval procedure affects public attitudes towards vaccination. Compared to an Emergency Use Authorization, choosing the more thorough...

We investigate whether the presence of a default interacts with the willingness of decision-makers to gather, process and consider information. In an online experiment, where about 2,300 participants choose between two compiled charity donation options worth $100, we vary the availability of...

We examine structural differences in growth vulnerabilities across countries associated with financial risk indicators. Considering trade openness, financial sector size, the public spending ratio and government effectiveness, our findings suggest the existence of a structural gap and a risk...

Financial professionals play a key role in financial markets and the financial industry as a whole. Researchers in experimental economics and finance have therefore started to employ financial professionals as experimental participants. We examine this recent development in the field by...

This paper shows that a transaction tax makes trades in decentralized markets more information sensitive and enlarges the range of information costs for which the equilibrium exhibits private information acquisition and endogenous adverse selection. A transaction tax reduces the probability of...

Experiments can complement other methods in identifying causal relationships and in measuring behavioral deviations from theoretical predictions. While the experimental method has long been central in many scientific disciplines, it was almost nonexistent in finance until the 1980s. To survey...

We report the results of an experiment to systematically investigate the influence of different settings in credence good markets on opportunism in the sellers' decisions. We find that, as predicted by a cognitive dissonance model, the specific choice of the design features might be less...

Firm-product data provide information for various research questions in international trade or innovation economics. However, working with this data requires harmonizing product classifications consistently over time to avoid internal validity issues. The researcher must consider product code...

Especially in many online markets, consumers can readily observe prices, but may need to further inspect products to assess their suitability. We study the effects of product differentiation and search costs on competition and market outcomes in a tractable model of price-directed consumer...
