, portfolio constraints can lead to situations where not all arbitrage opportunities are necessarily eliminated in equilibrium …. For a world with portfolio constraints the concept of no arbitrage has to be replaced by a weaker concept which we call no … unlimited arbitrage. Second, though we can characterize prices which allow no unlimited arbitrage by the existence of certain …

Can standard preferences explain the prices of out-of-the-money S&P 500 put options?

Benzoni, Luca; Collin-Dufresne, Pierre; Goldstein, Robert S. - 2011

The 1987 stock market crash occurred with minimal impact on observable economic variables (e.g., consumption), yet dramatically and permanently changed the shape of the implied volatility curve for equity index options. Here, we propose a general equilibrium model that captures many salient...

Explaining asset pricing puzzles associated with the 1987 market crash

Benzoni, Luca; Collin-Dufresne, Pierre; Goldstein, Robert S. - 2010

The 1987 market crash was associated with a dramatic and permanent steepening of the implied volatility curve for equity index options, despite minimal changes in aggregate consumption. We explain these events within a general equilibrium framework in which expected endowment growth and economic...

Stochastic modeling of private equity: an equilibrium based approach to fund valuation

Buchner, Axel; Kaserer, Christoph; Wagner, Niklas - 2006

In this paper, we present a new approach to measure the returns of private equity investments based on a stochastic model of the dynamics of a private equity fund. Our stochastic model of a private equity fund consists of two independent stages: the stochastic model of the capital drawdowns and...

How does the market variance risk premium vary over time? Evidence from S&P 500 variance swap investment returns

Konstantinidi, Eirini; Skiadopoulos, George - 2014

We explore whether the market variance risk premium (VRP) can be predicted. First, we propose a novel approach to measure VRP which distinguishes the investment horizon from the variance swap's maturity. We extract VRP from actual rather than synthetic S&P 500 variance swap quotes, thus avoiding...

Capital structure and financial flexibility: Expectations of future shocks

Lambrinoudakis, Costas; Neumann, Michael; Skiadopoulos, … - 2014

We test one of the main predictions of the financial flexibility paradigm that expectations about future firm-specific shocks affect the firm's leverage. We extract the expectations of small and large future shocks from the market prices of equity options. We find that expectations for future...
