We argue that, for a given level of scientific knowledge, tolerance and diversity are conducive to technological creativity and innovation. In particular, we show that variations in innovation within Prussia during the second industrial revolution can be ascribed to differences in religious...

We employ bootstrap methods (Efron (1979)) to test the effect of an important electoral reform implemented in Italy from 1993 to 2001, that moved the system for electing the Par-liament from purely proportional to plurality rule (for 75% of the seats). We do not find any effect on either the...

We analyze whether mayors’ prior occupation in the local public administration matters for their performance. In theory, mayors’ professional background may shape their competence in bureaucratic tasks. We use the example of grant receipts for visible investment projects for which mayors...

To discuss experimental results without discussing how they came about makes sense when the results are robust to the way experiments are conducted. Experimental results, however, are - arguably more often than not - sensitive to numerous design and implementation characteristics such as the use...

Economists are increasingly turning to the experimental method as a means to estimate causal effects. By using randomization to identify key treatment effects, theories previously viewed as untestable are now scrutinized, efficacy of public policies are now more easily verified, and stakeholders...

Ranking methods are fundamental tools in many areas. Popular methods aggregate the statements of 'experts' in different ways. As such, there are various reasonable ranking methods, each one of them more or less adapted to the environment under consideration. This paper introduces a new method,...

Social preference research has fundamentally changed the way economists think about many important economic and social phenomena. However, the empirical foundation of social preferences is largely based on laboratory experiments with self-selected students as participants. This is potentially...

This paper describes Gary Becker's theoretical models of marriage. At the micro-level, these are all rational choice models. At the market level, Becker offers two major types of models: partial equilibrium models based on Price Theory as taught by Marshall and Friedman and optimal sorting...

In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in sample estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation...

Recent large-scale replications of social science experiments provide important information on the reliability of experimental research. Unfortunately, there exist no mechanisms to ensure replications are done. We propose such a mechanism: journal-based replication, in which the publishing...
