This paper develops a model with multiple steady states (low tax and unemployment rate versus high tax and unemployment rate) in which equilibrium selection is not conditioned on a sunspot variable. Instead, large enough shocks initiate unavoidable transitions from one regime to the other. The...

The present paper makes a contribution to fill in a gap left open by dynamic theory and evolutionary economics as well. While the "closed loop" dynamic theory has explanation power in analyzing evolving economic systems at the price of neglecting the possible occurrence of non anticipated...

The paper considers price adjustment on the plane and derives global stability conditions for such dynamics. First, we examine the well-known Scarf Example, to obtain and analyze a global stability condition for this case. Next, for a general class of excess demand functions, a set of conditions...

We discover that letting agents pairwise sequentially exchange at "wrong" prices has a robust effect on prices at convergence. If the initial relative price for a good is cheaper than the equilibrium walrasian price due to initial endowments, the initial excess demand effect pushes resource...

Using differential games, this paper analyzes output controls of internationally shared renewable resources such as transboundary natural forests. A two-country, two-good (that is, shared-resource and nonresource based goods) general equilibrium trading model is employed for this purpose. Each...

In this paper, I construct a model of an exchange economy in which bankruptcy arises in a manner similar to what we observe. This model is a more realistic representation of some markets in which intertemporal assets are traded. Using standard and natural assumptions, I show that every economy...

Adam Smith set economists and examination question: what determines long-run normal prices and the associated rate of profit. The fundamental difficulty is that the long-run equilibrium prices of reproducible means of production (Smith's “natural” prices) must satisfy two conditions at the...

In this paper, Anything Goes: The Sonnenschein-Mantel-Debreu theorem (following the work of Sonnenchein (1972, 1973), Mantel (1974), and Debreu (1974)), has been applied to incomplete markets, Bottazzi, J.-M. and T. Hens (1996), in order to test the Ricardian equivalence hypothesis. In the...

We complement the Sonnenschein-Mantel-Debreu results by establishing that an exchange economy, i.e., preferences and endowments, that generates a given aggregate excess demand (AED) function is close to the economy that generates a perturbation of this AED. As a consequence, genericity and...

The present paper considers a class of general equilibrium economics when the primitive uncertainty model features uncertainty about continuous-time volatility. This requires a set of mutually singular priors, which do not share the same null sets. For this setting we introduce an appropriate...
