This paper proposes an aggregate deposit insurance premium design that is risk-based in the sense that the premium structure ensures the deposit insurance system has a target of survival over the longer term. Such a premium system naturally exceeds the actuarily fair value and leads to a growth...

An argument for adjusting Black Scholes implied call deltas downwards for a gamma exposure in a left skewed market is presented. It is shown that when the objective for the hedge is the conservation of capital ignoring the gamma for the delta position is expensive. The gamma adjustment factor in...

This paper estimates the price for restructuring risk in the U.S. corporate bond market during 1999-2005. Comparing quotes from default swap (CDS) contracts with a restructuring event and without, we find that the average premium for restructuring risk represents 6% to 8% of the swap rate...

A constrained informationally efficient market is defined to be one whose price process arises as the outcome of some equilibrium where agents face restrictions on trade. This paper investigates the case of short sale constraints, a setting which despite its simplicity, generates new insights....

This paper derives an equilibrium asset pricing model with liquidity risk. Liquidity risk is modeled as a stochastic quantity impact on the price from trading, where the size of the impact depends on trade size. Under a mild set of assumptions, we prove that an equilibrium price process exists...

This paper derives an equilibrium capital asset pricing model (CAPM) in a market with trading constraints and asset price bubbles. The asset price processes are general semimartingales including Markov jump-diffusion processes as special cases, and the trading constraints considered include...

In models of financial bubbles, the price of a stock is a priori typically unbounded, and this plays a fundamental role in the analysis of finite horizon local martingale bubbles. It would seem that price bubbles do not apply to bounded risky asset prices, such as bond prices. To avoid this...

We develop a dynamic simulation model for residential home prices in an economy where defaults on residential mortgages negatively affect housing prices and aggregate income. This simulation model enables us to study the impact of subprime defaults on prime borrowers and the impact of various...

In traditional thinking, an arbitrageur will trade immediately once an arbitrage opportunity appears. Is this the best strategy for the arbitrageur or it is even better to wait for the best time to trade so as to achieve the maximum profit? To answer this question, this paper studies the optimal...
