Network industries are now characterized by a regime of permanent innovation, while they continue to be fixed and sunk cost industries, due to the high level of investments in R&D and infrastructures. Players in these industries need to coordinate their investments; hence a threat of collusion....

The questioning of how public investments decisions are made leads to a two-level problematic. On the one hand, public decision makers have constrained resources that they have to use the best way they can. On the other hand, by choosing between alternative investments projects, decision makers...

According to economic theory, health insurance raises medical care consumptions by inducing ex-post moral hazard behavior, it is to say the purchase of health care that individual value below their production cost. Nevertheless, among the economists community, some suggest that these additional...

Small entrepreneurs in poor countries achieve relatively high marginal returns to capital but show only low re-investment rates. The literature is rather inconclusive about the possible causes. We explore whether ‘forced redistribution’, i.e. abusive demands by the kin, affects the...

In cost-utility analysis results are often processed in terms of QALY (Quality Adjusted Life Year). The duration of a given health state is weighted with a coefficient calculated based on its associated quality of life. Using such an indicator assumes two things: knowing the health state of the...

This paper studies efficient risk-sharing rules for the concave dominance order. For a univariate risk, it follows from a comonotone dominance principle, due to Landsberger and Meilijson (1994) [27], that efficiency is characterized by a comonotonicity condition. The goal of the paper is to...

This note analyzes some properties of optional two-part pricing in a two-type economy. First, the optimal contracts along the Paretian frontier are described. Then, the duality relation between the Rawlsian program and the discriminating monopoly is demonstrated. Last, this property is used to...

This paper derives the properties of the discount rate that should be applied to a public-sector project when the affected population has heterogeneous degrees of impatience. We show that, for any distribution of discount rates, the social discount rate has the following properties: it decreases...
