In single-obligor default risk modelling, using a background filtration in conjunction with a suitable embedding hypothesis (generally known as H-hypothesis or immersion property) has proven a very successful tool to separate the actual default event from the model for the default arrival...

Survey and option data are used to take a fresh look at the equity premium puzzle.Survey data on equity returns (Livingston survey) shows much lower expected excess returns than ex post data. At the same time, option data suggests that investors perhaps overestimate the volatility of equity...

In this paper we show how cross-sectional correlations between Private Equity (PE) and Public Market Equity (PM) returns can be approximated, resolving the lack of time series PE data. Based on a sample comprising 2,380 realized PE projects, we observe low crosssectional correlations between PE...

The price process in a financial market is driven by demand and supply. Statistical analyses have shown that price “feeds back” on future demand and supply. To date, few testable models have been proposed that offer an economic explanation for this relationship. In this paper, we investigate a...

In this paper we solve an intertemporal portfolio problem with correlation risk, using a new approach for the simultaneous modeling of stochastic correlation and volatility. The solutions of the model are in closed form and include an optimal portfolio demand for hedging correlation risk. We...

Like many financial contracts, derivatives are subject to default risk. A very popular mechanism in derivatives markets to mitigate the risk of non-performance on contracts is margining. By attaching collateral to a contract, margining supposedly reduces default risk. The broader impacts of the...

Using a panel data set of U.S. non-financial firms with geographically segmented firm-level information on currency exposures, exchange rates, and foreign currency derivatives, we document that managers adjust derivatives holdings in response to past foreign exchange returns. We interpret this...

In this paper, we extend the earlier results of Jeanblanc and Valchev (2003) in the single name case to the case of multiple defaults of the issuers in a concentrated industry or homo- geneous bond market. We provide solutions for the pairwise default correlations and credit spreads in an...

A generalized correlated random walk is a process X_k of partial sums of random variables Y_j such that (X,Y) forms a Markov chain. For a sequence X^n of such processes where each Y^n_j takes only two values, we prove weak convergence to a diffusion process whose generator is explicitly...
