We study an economy with segmented financial markets and strategic arbitrageurs who link these markets. We show that the equilibrium of the arbitraged economy is asymptotically Walrasian in the sense that it converges to the equilibrium of an appropriately defined competitive economy with no...

This paper contributes to the literature on default in general equilibrium. Borrowing and lending takes place via a clearing house (bank) which monitors agents and enforces contracts. Our model develops a concept of bankruptcy equilibrium that is a direct generalization of the standard general...

This paper suggests that non-fundamental component in asset prices is one of the drivers of the financial and credit cycle. The presented model builds on the financial accelerator literature by including a stock market where limitedly-liable investors trade stocks of productive firms with...

We compare laboratory general equilibrium economies in which maintenance of a depreciating public facility is financed either by anonymous voluntary contributions or taxes. Agents individually allocate their private goods between consumption and investment in production. The experimental...

Survival conditions ensure the presence of consumptions that cost less than the total contingent income of agents in general equilibrium models. These conditions are generally fulfilled in competitive equilibrium. This paper shows the existence of equilibrium for incomplete-market economies...

In a model of asset markets with transaction costs, we find a sufcient condition for an increase in transaction costs to increase buying prices, decrease selling prices, decrease the trading volume, and make all active investors worse off. The sufficient condition is met by all CARA utility...

We provide an equilibrium multi-asset pricing model with micro-founded systemic risk and heterogeneous investors. Systemic risk arises due to excessive leverage and risk taking induced by free-riding externalities. Global risk-sensitive financial regulations are introduced with a view of...

We present an experiment designed to test the Modigliani-Miller theorem. Applying a general equilibrium approach and not allowing for arbitrage among firms with different capital structures, we find that, in accordance with the theorem, participants well recognize changes in the systematic risk...

I propose a general-equilibrium model with investment heterogeneity to investigate the dynamics of Tobin's q over time, and more precisely why firms tend to migrate from value to growth and viceversa. Firms are assumed to have two types of investment opportunities: i) reinvest capital in the own...
