Where do new resources come from? We build on the premise that environments feature vast reservoirs of latent resources, uses and resource combinations. However, identifying this value can be costly and difficult. In this paper we consider the thought experiment of an endowment-less firm and how...

We study the existence of equilibria with endogenously complete markets in a continuous-time, heterogenous agents economy driven by a multidimensional diffusion process. Our main results show that if prices are real analytic as functions of time and the state variables of the model then a...

This article shows that the presence of portfolio constraints can give rise to rational asset pricing bubbles in equilibrium even if there are unconstrained agents in the economy who can bene t from the corresponding limited arbitrage opportunities. Furthermore, it is shown that when they are...

We study an economy populated by three groups of logarithmic agents: Constrained agents subject to a portfolio constraint that limits their risk-taking, unconstrained agents subject to a standard nonnegative wealth constraint, and arbitrageurs with access to uncollateralized credit. Such credit...

We establish that, when the number of agents is sufficiently large, but finite, there are open sets of economies with constrained Pareto inefficient equilibria, and provide a simple sufficient condition for CP inefficiency. We also show that there are open sets of economies with CPO equilibria.

Bei unvollkommenen Märkten und numerairen Vermögen gibt es eine offene Menge an Volkswirtschaften, so dass die Gleichgewichtsverteilung durch eine veränderte Anfangsverteilung verbessert werden kann. Dies stärkt das klassische Ergebnis der eingeschränkten Pareto Ineffizienz von...

We present comprehensive evidence in support of giving liquidity equal standing to size, value/growth, and momentum as investment styles, as defined by Sharpe (1992). First, we show that financial market liquidity, as identified by stock turnover, is an economically significant indicator of...

We study a dynamic general equilibrium model with costly-to-short stocks and heterogeneous beliefs. The closed-form solution to the model shows that costly short sales drive a wedge between the valuation of assets that promise identical cash flows but are subject to different trading...

The paper presents and studies a new concept of coalition domination for incomplete markets. It was elaborated applying a contractual approach and based on the notion of fuzzy contractual allocation, see Marakulin (2011, 2013). Core allocations are implemented by the net trades (webs of...

A dynamic stochastic model of global equilibrium, where countries outside the U.S. face higher risk than the U.S. itself, predicts current account surpluses in the RoW and U.S. deficits. With Loss Aversion, such precautionary savings can cause substantial 'global imbalances', particularly if...
