How many comparison dimensions individuals consider when they are asked to judge how similar two different objects are? I address individual heterogeneity in the number of comparison dimensions with data from a laboratory experiment. I estimate the smallest number of dimensions such that objects...

In this paper, I address the U-shaped dynamics (a decrease followed by an increase) in the age at first marriage during the twentieth century. First, I show that the U-shaped dynamics have been steeper in Western that in other countries. Second, I find that these dynamics in Western Europe are...

COVID-19 mystery feeds the belief that the reported morbidity rates are not related to the true ones and that large parts of the population are already infected, the virus is not very dangerous, and the lockdown is unnecessary. Yet one observes two very strong correlations that disprove this...

This paper links between Beckerian literature that shows that marriage is a normal good with respect to male income and the literature that explores cultural changes as a result of exogenous events. I use the oil crisis of the 1970s as a positive shock on some males. The analyzed outcome is...

This paper takes advantage of a natural experiment, in which Soviet Jewish immigrants were quasi-randomly allocated of to the U.S. and Israel. I find that young women who immigrated as children follow similar fertility profiles in the two host countries. In Israel, they are also similar to...
