We model political information acquisition in large elections, where the probability of being piv- otal is negligible. Our model builds on the assumption that informed citizens enjoy discussing politics with other informed citizens. The resulting information acquisition game exhibits strate- gic...

We built a unique dataset of 300,000 famous people born between Hammurabi's epoch and 1879, Einstein's birth year. It includes, among other variables, the vital dates, occupations, and locations of celebrities from the Index Bio-bibliographicus Notorum Hominum (IBN), a very comprehensive...

We propose a new theory of the demographic transition based on the evidence that body development during childhood is an important predictor of adult life expectancy. Fertility, childhood development, longevity, education and income growth all result from individual decisions. Parents face a...

We propose four arguments favoring the idea that medical effectiveness, adult longevity and height started to increase in Europe before the industrial revolution. This may have prompted households to increase their investment in human skills as a response to longer lives and initiated the...

Consider an economy populated by males and females, both rich and poor. The society has to choose one of the following marriage institutions: polygyny, strict monogamy, and serial monogamy (divorce and remarriage). After having identified the conditions under which each of these equilibria...

We investigate the role of manipulation in a model of opinion formation where agents have opinions about some common question of interest. Agents repeatedly communicate with their neighbors in the social network, can exert some effort to manipulate the trust of others, and update their opinions...

We consider a linguistically diversified society that has to select a set of languages to be used for official purposes. We examine the notion of language disenfranchisement that is created when one or more languages fail to be included in the list of the official ones, implying that some...

The policy of official multilingualism is one of the most important and fundamental principles of the Union. However, a large number of official languages imposes substantial financial, communication and legal costs. We address the merits of extensive multilingualism and formulate an analytical...

We examine patterns of acquiring non-native languages in a model with two linguistic communities with heterogeneous learning skills, where every individual faces the choice of self-learning the foreign language or acquiring it at a profit-maximizing linguistic school. We consider a one-school...

We provide an explanation for why estate taxation is surprisingly little used over the world, given the skewness of the estate distribution. Taxing estates implies meddling with intra-family decisions, which may be frown upon by many. At the same time, the concentration of estates means that a...
