We study endogenous leverage in a general equilibrium model with incomplete markets. We prove that in any binary tree leverage emerges in equilibrium at the maximum level such that VaR=0, so there is no default in equilibrium, provided that agents get no utility from holding the collateral. When...

We show that binomial economies with financial assets are an informative and tractable model to study endogenous leverage and collateral equilibrium: endogenous leverage can be highly volatile, but it is always easy to compute. The possibility of default can have a dramatic effect on...

This paper investigates collective denial and willful blindness in groups, organizations and markets. Agents with anticipatory preferences, linked through an interaction structure, choose how to interpret and recall public signals about future prospects. Wishful thinking (denial of bad news) is...

This paper extends the Diamond and Dybvig (1983) model to study how the possibility of a bank run affects the investment decisions of banks and asset pricing. It is assumed that a bank run is triggered by extrinsic sunspot variables. The model generates two types of equilibria: a no-default...

This paper investigates the drivers of cross-currency basis spreads, which were historically close to zero but have widened significantly since the start of the financial crisis. Credit and liquidity risk, as well as supply and demand have often been cited as general factors driving...

This is the first paper to theoretically analyze the temporary reversal of the downward trend in financial assets, also known as dead cat bounce or bear market rally. We show that preferences according to cumulative prospect theory lead an investor to take ex- cessive risk and unprofitable...

This article is a prologue to the article "Why Markets are Inefficient: A Gambling 'Theory' of Financial Markets for Practitioners an Theorists", available here: 'http://ssrn.com/abstract=2925532' http://ssrn.com/abstract=2925532. It presents important background for that article - why gambling...

A discrete-time dynamic asset-pricing model specifies the economic rationale for a rich array of price dynamics. Two boundedly-rational investors with different risk preferences trade periodically, where excess supply is cleared by a tâtonnement. Cast at the core of asset-pricing modelling,...

We assess the quantitative implications of collateral re-use on leverage, volatility, and welfare within an infinite-horizon asset-pricing model with heterogeneous agents. In our model, the ability of agents to reuse frees up collateral that can be used to back more transactions. Re-use thus...
