We propose a spatial search-matching model where both job creation and job destruction are endogenous. Workers are ex ante identical but not ex post since their job can be hit by a technological shock, which decreases their productivity. They reside in a city and commuting to the job center...

We develop a model where information about jobs is essentially obtained through friends and relatives, i.e. strong and weak ties. Workers commute to a business center to work and to interact with other people. We find that housing prices increase with the level of social interactions in the city...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

We survey the literature on the economic consequences of the structure of social networks. We develop a taxonomy of "macro" and "micro" characteristics of social interaction networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...

This paper introduces the Stata commands checkax, aei, and powers as a bundle within the package rpaxioms. The first command allows the user to test whether consumer demand data satisfy a number of revealed preference axioms at a given efficiency level, the second command calculates measures of...

The Houtman-Maks index is a measure of the size of a violation of utility maximizing (i.e., rational) behavior. This note introduces the Stata command hmindex, which calculates the Houtman-Maks index for a data set of prices and observed choices of a consumer. The command is illustrated with an...
