Bei Public Private Partnerships (PPP) spielt der Wirtschaftlichkeitsvergleich eine entscheidende Rolle. Er dient zur Ermittlung von Effizienzvorteilen und Einsparungen einer Realisierungsvariante (öffentlicher Eigenbau oder privatwirtschaftlich) und als Argumentationsgrundlage sowie...

What happens to the distribution of public resources when undocumented migrants obtain legal status through nation-wide amnesty? In this paper, we exploit variation in legal status from the 1986 Immigration Reform and Control Act (IRCA) to answer this question and find that state governors, of...

Through extending a standard Grossman and Stiglitz (1980) noisy rational expectations economy by a heterogeneous signal structure with signal-specific differences in uncertainty, we show that price momentum as well as reversal are not intrinsically at odds with rational behavior. Differences in...

Generalizing the idea that price momentum can be explained by different levels of uncertainty inherent in the information structure, we implement signal-specific differences in uncertainty in a Kyle type model of strategic trading. We derive the equilibrium in a single-auction setting as well as...

We analyze how economic conditions at the time of arrival affect the economic integration of family-sponsored migrants in the U.S. Our identification strategy exploits long waiting times for family-sponsored immigration visas that decouple the migration decision from economic conditions at the...

The widespread availability of digital technologies has made mandatory price disclosure policies (MPD) a convenient tool for policymakers to increase price transparency and foster competition. The literature has shown that these can increase or decrease prices. We shed light on the circumstances...

We analyze how economic conditions at the time of arrival affect the economic integration of family-sponsored migrants in the U.S. Our identification strategy exploits long waiting times for family-sponsored immigration visas that decouple the migration decision from economic conditions at the...

We analyze the impact of economic conditions at arrival on the economic integration of family-sponsored migrants in the U.S. A one pp higher unemployment rate at arrival decreases annual wage income by four percent in the short run and two percent in the longer run. The loss in wage income...

Combining a theoretical model of imperfect information with empirical evidence, we show how the effect of providing price information to consumers depends on how well informed they are beforehand. Theoretically, an increase in consumer information decreases prices more, the fewer ex ante...

We study the impact of immigrant legalization on fiscal transfers from state to local governments in the United States, exploiting variation in legal status from the 1986 Immigration Reform and Control Act (IRCA). State governments allocate more resources to IRCA counties, an allocation that is...
