In this paper we study BSDEs arising from a special class of backward stochastic partial differential equations (BSPDEs) that is intimately related to utility maximization problems with respect to arbitrary utility functions. After providing existence and uniqueness we discuss the numerical...

We analyze the impact of takeover threats on long term relationships between the target owners and other stakeholders. In the absence of takeovers, stakeholders’ bargaining power increases their incentive to invest but reduces the owners’ incentive to invest. The threat of a takeover that...

We use in this chapter the viability/capturability approach for studying the problem of dynamic valuation and management of a portfolio with transaction costs in the framework of tychastic control systems (or dynamical games against nature) instead of stochastic control systems. Indeed, the very...

This study reconsiders the problem of hedging a liability by a portfolio made of a riskless asset and an underlying (underlying).

This paper examines how credit derivatives have changed the construction of an efficient portfolio. Credit derivatives provide a way of gaining exposure to credit risk alone, to the exclusion of interest rate risk. They also permit a relatively easy use of leverage. We examine two types of...

The diversifying power of inflation-linked (IL) bonds relative to traditional asset classes has changed significantly. In this paper, we study the dynamics of conditional volatilities and correlations for three asset classes, IL bonds, nominal bonds, and equities, in the USA and Europe. Using a...

The authors examine the advantages of incorporating strategic exposure to equity volatility into the investment opportunity set of a long-term equity investor. They consider two standard volatility investments: implied volatility and volatility risk premium strategies. An analytical framework,...

This article examines how the inception of an ETF market impacts several dimensions of the liquidity of the ETF-underlying-index stocks. In contrast with previous research, our evidence is based on an ETF market where liquidity providers (LPs) act as market makers. We find that: (1) the market...
