The credit derivatives market provides a liquid but opaque forum for secondary market trading of banking assets. I show that when entrepreneurs rely upon the certification value of bank debts to obtain cheap bond market insurance, the existance of a credit derivatives market may cause them to...

Allegations of British capital market failure are numerous, range from claims of domestic investor bias before 1914 to charges of short-termism against institutional investors towards the end of the last century, and are frequently contentious. This paper revisits this literature by pointing up...

We develop a model in which cash-constrained entrepreneurs seek a venture capitalist (VC) to finance a new firm. Costly monitoring is employed by VCs to reduce entrepreneurial moral hazard. When monitoring reveals poor performance, VCs want to punish the entrepreneur with liquidation. However,...

We present a model of cash constrained entrepreneurs who need an investor to finance their project. Investors can either be uninformed, such as individual bondholders, or informed, such as venture capitalists and banks. There is an entrepreneurial moral hazard problem, which can be partially...

This paper studies the contracting problem between banks and their bankers, embedded in a competitive labour market for banker talent.  To motivate effort banks must use some variable remuneration.  Such remuneration introduces a risk-shifting problem by creating incentives to inflate early...

This study outlines a new theory linking industrial structure to optimal employment contracts and value reducing risk taking.  Firms hire their executives using optimal contracts derived within a competitive labour market.  To motivate effort firms must use some variable remuneration.  Such...

This paper studies banker remuneration in a competitive market for banker talent.  I model, and then calibrate, the default risk of the banks generated by investments and remuneration pressures.  Competing banks prefer to pay their banking staff in bonuses and not in wages as risk sharing on...

 This paper assesses the quantitative impact of ambiguity on the historically observed financial asset returns and prices. The single agent, in a dynamic exchange economy, treats the conditional uncertainty about the consumption and dividends next period as ambiguous. We calibrate the agent's...

This is a draft Chapter from a book by the authors on “Levy Driven Volatility Modelsâ€.

We discuss computational aspects of likelihood-based estimation of unvariate ARFIMA (p,d,q) models. We show how efficient computation and simulation is feasible, even for large samples. We also discuss the implementation of analytical bias corrections.
