We model the choices of a monopolist who faces a partially uninformed population of consumers. She aims at expanding demand by exploiting his (limited) knowledge about consumers’ social network. She offers rewards to current clients in order to induce them to activate their social network and...

This paper analyses the practice of firms to offer different prices to consumers according to the past purchase behaviour (BBPD) in the context of two-sided markets. In a two-period model, two platforms compete for heterogeneous firms and consumers. Platforms are allowed to discriminate prices...

This article studies the effects of Behaviour-Based Price Discrimination (BBPD) in a horizontally and vertically differentiated duopoly. In a two-period model, firms are allowed to condition their pricing policies on the past purchase behaviour of consumers. The paper shows two different types...

Globalization has been accompanied by rising pressure from advocacy non-governmental organizations (NGOs) on multinational firms to act in socially-responsible manner. We analyze how NGO pressure interacts with industry structure, using a simple model of NGO-firm interaction embedded in an...

This paper systematizes the results of the empirical literature on development non-governmental organizations (NGOs), drawing both from quantitative and qualitative analyses, and constructs a set of basic facts about these organizations. These basic facts concern the size of the development NGO...

In the robust statistics literature, a wide variety of models have been developed to cope with outliers in a rather large number of scenarios. Nevertheless, a recurrent problem for the empirical implementation of these estimators is that optimization algorithms generally do not perform well when...

A frequent characteristic of worker cooperatives is the tendency to reinvest a large share of profits into asset locks: a common fund, indivisible and not appropriable by members, neither upon quitting, nor at the end of the firms life. To explain this behaviour, I introduce the hypothesis that...

The idea that corruption may, in some situations, be beneficial is widely studied within the context of growth. In the field of entrepreneurship, a unique paper by Dreher and Gassebner (2011) explicitly documents it. Their findings support the assumption that corruption “greases the wheels”...

We use a unique natural experiment in order to assess the impact of positive discrimination in India on targeted groups' educational attainment. We take advantage of the harmonization of the Scheduled Castes lists within the Indian states taking place in 1976 to measure the increase of the...

Mission-driven nonprofit organizations compete for donations through fundraising activities. Such competition can lead to inefficient outcomes, if nonprofits impose externalities on each others' output. This paper studies the sustainability of fundraising coordination agreements, using a...
