This article uses Survey of Households' Income and Wealth microdata to investigate the role the Scala Mobile played in the initial fall and subsequent rise in earnings inequality in Italy between 1977 and 1993. The Scala Mobile was a wage indexation mechanism granting the same absolute wage increase to all employees as prices rose, thereby potentially compressing wage differentials. Over time, the potential equalizing effect of this mechanism fell. This article argues that the rise in inequality from the mid‐1980s was a response to the compression of differentials operated over the previous years by the Scala Mobile.

This paper uses administrative longitudinal microdata on junior high school students in Uruguay to measure the effect of grade failure on students' subsequent school outcomes. Exploiting the discontinuity induced by a rule establishing automatic grade failure for pupils with more than three failed subjects, I show that grade failure leads to substantial dropout and lower educational attainment even four to five years after grade failure occurred.

This paper exploits the variation in the legal minimum working age across states in 1920 America in order to identify households' labor supply responses to exogenous changes in children's labor force participation. Using micro data on urban households from the U.S. Census, I find evidence that as a child moves to the labor market his siblings are less likely to work and more likely to attend school. I find no significant effect on parents' labor supply.

Can digital information and communication technology foster mass political mobilization? We use a novel georeferenced data set for the entire African continent between 1998 and 2012 on the coverage of mobile phone signal together with georeferenced data from multiple sources on the occurrence of protests and on individual participation in protests to bring this argument to empirical scrutiny. We find that while mobile phones are instrumental to mass mobilization, this only happens during economic downturns, when reasons for grievance emerge and the cost of participation falls. The results are in line with insights from a network model with imperfect information and strategic complementarities in protest occurrence. Mobile phones make individuals more responsive to both changes in economic conditions—a mechanism that we ascribe to enhanced information —and to their neighbors' participation—a mechanism that we ascribe to enhanced coordination .
