German policy during the Eurozone crisis supposedly follows an ordoliberal tradition. In this paper, we discuss to what extent this contention holds and to what extent Germany pragmatically responded to different crisis phenomena. A proper analysis of ordoliberal thinking reveals that the...

Policies and explicit private incentives designed for self-regarding individuals sometimes are less effective or even counterproductive when they diminish altruism, ethical norms and other social preferences. Evidence from 51 experimental studies indicates that this crowding out effect is...

A nudge is a non-coercive paternalistic intervention that attempts to improve choices by manipulating the framing of a decision problem. As any paternalism, it faces the difficulty of determining the appropriate welfare criterion. We propose a welfare-theoretic foundation for nudging similar in...

For thousands of years, humans have known the value of honeybees in agriculture. Their pollination services are crucial for the mankind, the Global ecosystem and food production. The recently documented decline of the honeybee colonies in the world is alarming and may threaten the whole living...

Using new data on linguistic diversity across and within countries, we examine novel channels though which language affects trade patterns and economic welfare. We find that linguistic similarity within a country accounts for about 10 percent of estimated "home bias", demonstrating the...

Much economic analysis derives policy recommendations based on social welfare criteria intended to model the preferences of a policy maker. Yet, little is known about policy maker's normative views in a way amenable to this use. In a behavioral experiment, we elicit German legislators' social...

Empirical evidence suggests that individuals often evaluate options relative to a reference point, especially seeking to avoid losses. In this paper, we provide the first welfare analysis under reference-dependent preferences. We decompose the welfare impact of changes in reference points and...

James Buchanan would have celebrated his 100th birthday in 2019. This serves as an inspiration to look at the future of public choice and the question of how much normativity public choice can bear. In our analysis we draw parallels between public choice and German ordoliberalism (and its source...

The interaction of monetary and fiscal policies is a crucial issue in a highly integrated economic area as the European Union. We argue that EMU, which introduced a common monetary policy and restrictions on fiscal policy at the national level, increases the need for macroeconomic policy...

The paper addresses the question what effects the enlargement of a monetary union will have on necessary structural reforms in the (low distortion) member countries and the (high distortion) candidate countries. While monetary union lowers reforms in the candidate countries, members of the...
