We study strategic investment decisions in multi-stage contests with heterogeneous players. Our theoretical model of a round-robin rank-order tournament predicts that players conserve resources in a current contest to spend more in the subsequent contest if the degree of heterogeneity in the...

We use two randomized controlled trials in Bangladesh to study a simple water conservation technology for rice production called “Alternate Wetting and Drying (AWD)”. Despite proven results in agronomic trials, our first experiment shows that AWD only saves water and increases profits in...

In order to get the COVID-19 pandemic under control, most governments around the globe have adopted some sort of containment policies. In the light of the enormous costs of these policies, in many countries highly controversial discussions on the adequacy of the chosen policies evolved. We...

We study the effects of federal purchases on firm investment using a novel panel dataset that combines federal procurement contracts in the United States with key financial firm-level information. Using panel fixed-effect models, propensity score matching, and inverse probability weighting...

We estimate the effects of a mandate allocating a third of corporate board seats to workers (shared governance). We study a reform in Germany that abruptly abolished this mandate for certain firms incorporated after August 1994 but locked it in for the older cohorts. In sharp contrast to the...

Tax legislation, fiscal authorities, and tax courts create tax uncertainty by frequent tax reforms and various different interpretations of the tax law. Moreover, investors generate model-specific tax uncertainty by using simplified models that anticipate the actual tax base incorrectly. I...

This paper estimates the causal effect of corporate tax hikes on firm investment based on more than 1,400 local tax changes. By observing planned and realized investment volumes in a representative sample of German manufacturing firms, we can study how tax hikes induce firms to revise their...
