| dc.description.abstract | This thesis deals with economic models in the presence of externalities. The
thesis consists of three chapters.
In chapter 1, we consider a general model of production economies with
consumption and production externalities. That is, the choices of all agents
(households and firms) affect individual consumption sets, individual
preferences and production technologies. Describing equlibria in terms of first
order conditions and market clearing conditions, and using a homotopy, under
differentiability and boundary conditions, we prove the non-emptiness and
compactness of the set of competitive equilibria with consumptions and prices
strictly positive.
In chapter 2 we consider a general model of private ownership economies with
consumption and production externalities. Showing by an example that basic
assumptions are not enough to guarantee a regularity result in the space of initial
endowments, we provide sufficient conditions for the regularity in the space of
endowments and transformation functions.
In chapter 3 we study the testability implications of public versus private
consumption in collective models of group consumption. To the contrary at the
previous literature, we find that assumptions regarding the public or private
nature of specific goods do have testability implications, even if one only
observes the aggregate group consumption. In fact, these testability implications
apply as soon as the analysis includes three goods and four observations. In our
opinion, our revealed preference approach obtains stronger testability
conclusions because it focuses on conditions which involve personalized prices
and personalized quantities, although we do not require that personalized prices
and personalized quantities are observable. [edited by author] | en_US |
