In this paper I develop the Discrete Choice Analytically Flexible (DCAF) model of demand for differentiated products. DCAF relaxes the constraints imposed on the matrix of own- and cross-price elasticities of demand by popular analytic discrete choice models such as the Multinomial Logit (MNL)...

Wealthy individuals often voluntarily provide public goods that the poor also consume. Such philanthropy is perceived as legitimizing one’s wealth. Governments routinely exempt the rich from taxation on grounds of their charitable expenditure. We examine the normative logic of this exemption....

There is a large econometric literature that examines the economic assimilation of immigrants in the United States and elsewhere. On the whole immigrants are seen as atomistic individuals assimilating in a largely anonymous labour market, a view that runs counter to the spirit of the equally...

In this chapter, we provide an overview on the literature on key players in networks. We first introduce the theoretical concept of the key player, which is the agent that should be targeted by the planner so that, once removed, she will generate the highest level of reduction in total activity....

We survey the literatures on the economic consequences of the structure of social networks. We develop a taxonomy of 'macro' and 'micro' characteristics of social inter-action networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...

This study explores the effect of several personal religion-related variables on social behaviour, using three paradigmatic economic games: the dictator (DG), ultimatum (UG), and trust (TG) games. A large carefully designed sample of a Spanish urban adult population (N=766) is employed. From...

Can we identify the members of a community who are best- placed to diffuse information simply by asking a random sample of in- dividuals? We show that boundedly-rational individuals can, simply by tracking sources of gossip, identify those who are most central in a network according to...

The very same forces that induce economists to conclude that regulators are captured should lead us to conclude that the economic profession is captured as well. As evidence of this capture, I show that papers whose conclusions are pro-management are more likely to be published in economic...

In this paper, we investigate the impact of peers on own outcomes where all agents embedded in a network choose more than one activity. We develop a simple network model that illustrates these issues. We differentiate between the ‘seemingly unrelated’ simultaneous equations model where...

In this chapter, we provide an overview of research on neighborhoods and social networks and their role in shaping behavior and economic outcomes. We include discussion of empirical and theoretical analyses of the role of neighborhoods and social networks in crime, education and labor-market...
