In this paper we provide necessary and sufficient conditions for the excess demand function of a pure exchange economy to be globally invertible so that there is a unique equilibrium. Indeed, we show that an excess demand function is globally invertible if and only if its Jacobian never vanishes...

The aim of this paper is to prove that if the consumption set of an economy with incomplete financial markets is semi-algebraic, then the corresponding pseudo-equilibrium manifold is also semi-algebraic. For this, we proceed by constructing an incomplete financial economy with real assets and...

This work extends the Sard-Smale Theorem to maps between convex subsets of Banach spaces that may have an empty interior.

In this paper we generalize Magill and Shafer's analysis of generically complete markets in the presence of an open-ended horizon. Until now, the genericity argument in Duffie and Shafer has no satisfactory generalisation to the case of an open ended horizon. These difficulties are threefold:...

We provide an axiomatic framework for exchange markets with a willingnessto- pay/willingness-to-accept discrepancy. First, we obtain a two parameter family of market invariants under price-scaling representing the excess demand. One of the parameters can be identified as endowment. The other is...

This paper tracks the consequences of individuals' desire to align their location with their social preferences. The social preference studied in the paper is distaste for relative deprivation, measured in a cardinal manner. Location is conceived as social space, with individuals choosing to...

We report the results of a combination of a dictator experiment with either a "social planner" or a "veil of ignorance" experiment. The experimental design and the analysis of the data are based on the theoretical framework proposed in the companion paper by Becker, Häger, and Heufer (BHH,...

We provide a framework to decompose preferences into a notion of distributive justice and a selfishness part and to recover individual notions of distributive justice from data collected in appropriately designed experiments. "Dictator games" with varying transfer rates used in Andreoni and...
