We consider a pure exchange, general equilibrium model, with two periods and a finite number of states, commodities, numeraire assets, and households. Participation in the asset markets is restricted in a household specific manner, imposing upper bounds on the amounts of borrowing which can be...

We consider a model with real assets and restricted participation described by household specific price dependent short selling constraints. We show existence of equilibria for all elements in an explicitly characterized large subset of the set of economies.

We consider a pure exchange, general equilibrium model, with two periods and a finite number of states, commodities, numeraire assets, and households. Participation in the asset markets is restricted in a household specific manner, imposing upper bounds on the amounts of borrowing which can be...

In this paper we analyze the effects of restricted participation in a two-period gen- eral equilibrium model with uncertainty in the second period and real assets. Similar to certain arrangements in the market for bank loans, household borrowing is restricted by a household-specific wealth...

The purpose of the paper is to argue that exogenous changes lowering wages may imply an increase of unemployment. To support that viewpoint, we use a general equilibrium approach. In that framework, we substitute the labour market clearing equation, which by very definition insures full...

We consider an incomplete market model with numeraire assets. Each household faces an individual constraint on its participation in the asset market. In related literature, the constraint is described by a function whose sole argument is the asset portfolio. On the contrary, in our analysis the...

In this paper we propose a model in which the real side of the economy, described via a Keynesian good market approach, interacts with the stock market with heterogeneous speculators, i.e., optimist and pessimist fundamentalists. Employing analytical and numerical tools, we detect the mechanisms...

We develop a macroeconomic behavioral model in order to analyze the interactions between real and financial markets. The real subsystem is represented by a simple Keynesian income-expenditure model, while the financial subsystem is represented by an equilibrium stock market with heterogeneous...

In this paper we show how a rich variety of dynamical behaviors can emerge in the standard Keynesian income-expenditure model when a nonlinearity is introduced, both in the cases with and without endogenous government spending. A specific sigmoidal functional form is used for the adjustment...
