A vast recent literature has stressed social fragmentation's negative impact on the provision of public goods. It has been established theoretically that social fragmentation engenders discord and thereby undermines public goods provision. Empirical research has produced mixed results about this...

A vast recent literature has stressed social fragmentation's negative impact on the provision of public goods. This is a key issue, given that public goods availability has been reckoned as crucial to economic development, while developing countries' societies often exhibit high degrees of...

We study the testability implications of public versus private consumption. The distinguishing feature of our approach is that we start from a revealed preference characterization of collectively rational behavior. Remarkably, we find that assumptions regarding the public or private nature of...

This paper provides an explanation of the emergence of the standars textbook definition of public goods in the middle of the 20th century. It focuses on Richard Musgrave's contribution in defining public goods as non-rival and non-excludable – from 1939 to 1969. Although Samuelson's...

In a simple public good economy, we propose a natural bargaining procedure whose equilibria converge to Lindahl allocations as the cost of bargaining vanishes. The procedure splits the decision over the allocation in a decision about personalized prices and a decision about output levels for the...

Unlike partial equilibrium analysis which study the equilibrium of a particular market under the clause "ceteris paribus" that revenues and prices on the other markets stay approximately unaffected, the ambition of a general equilibrium model is to analyze the simultaneous equilibrium in all...

Most of the international asset pricing models are developed in the situation where purchasing power parity (PPP) is not respected. Investors of different countries do not agree on expected security returns. However, in this case, an equilibrium on the international assets market may exist but...

We consider a family of exchange economies where consumers have multiprior preferences representing their ambiguity aversion. Under a linear independence assumption, we prove that regular economies are generic. Regular economies exhibit enjoyable properties: odd finite number of equilibrium...

Within a standard framework à la Arrow-Debreu, we investigate the dynamics emerging from the interactions of heterogeneous households and firms that are adaptive price setters and financially constrained. We show that depending on the stringency of the financial constraints the model can settle...

We build a general equilibrium model with endogenous borrowing constraints compatible with credit segmentation. There are personalized trading restrictions connecting prices with both portfolio constraints and consumption possibilities, a setting which has not thoroughly been addressed by the...
