Every year, as the International Women’s Day approaches, a classic topic for the media is to summarize statistics related to the gender wage gap . The empirical evidence is overwhelming: differences between men and women in the labor market are persistent in all countries. If we look at Europe and US data in recent years […]
The literature of experimental economics has documented that individuals consistently make voluntary payments. Two methodological questions arise from this fact. First, which are the precise drivers of this pro-social behavior and, second, whether these findings can be extended to real life situations. Tobias Regner (2014) addresses these questions comparing theoretical and laboratory results with the […]
The most distinctive feature of modern economics is probably its reliance on the methodology of mathematical model building. The final aim of scientific model building is illuminating real phenomena; furthermore, models are basically logical arguments, whose main virtue is that they allow us to see very clearly what follows, and also what does not follow […]
I will end this survey of the main contributions to the economics of scientific knowledge (ESK) by discussing the works which attempt to offer a more or less systematic conception of the process of scientific discovery; in this entry, I will talk about ‘institutionalist’ theories, i.e., those that abstain from using mathematical models. The first […]
The relative wage of high-skilled to low-skilled workers began to increase in US manufacturing industries in the late 1980s, and this phenomenon was also observed in Mexico. At the same time, the US–Mexican trade as a percentage of US GDP increased dramatically during the same period. Does this mean that trade is behind the observed […]
Voice and exit are often alternative ways of exerting influence, but with regard to voting the exit option spells no influence; only voice can have an effect[…] A. Lijphart In polls many citizens express some dissatisfaction with politicians. Usual ways to voice this dissatisfaction in elections are absenteeism, spoiled or blank vote, or voting for […]
It is estimated that at least 860 million people live in slums, a number that has been growing by six million a year from 2000 to 2010 (UN-Habitat 2012) . The study of slums worldwide is a very complex problem. We have no good model to study their economic performance, no systematic data and no […]
Israeli nurseries are particularly famous amongst economists (at least, amongst experimental economists). An already classical study shown that, following a ‘natural experiment’ in which some day-care centers opted for issuing a fine to parents for late children’s pickups, while other nurseries didn’t, not only helped to decrease (as expected) the frequency of late pickups, but […]
This article summarizes a review of the literature presented in Sacerdote (2011) . I thank Ricardo Mora for bringing it to my attention. The simplest model of behavioral genetics assumes that child outcomes (Y) are produced by a linear and additive combination of genetic inputs (G), shared environment (F) and unexplained factors (S). For instance […]
The first known application of modern economic techniques to solving epistemic problems in science was very explicit in describing the value of a scientific theory as the difference between ‘costs’ and ‘benefits’. I’m referring to Charles Sanders Peirce’s ‘Note of the Theory of the Economy of Research’, published in 1879, less than a decade after […]
