We survey theoretical developments in the literature on the limits of arbitrage. This literature investigates how costs faced by arbitrageurs can prevent them from eliminating mispricings and providing liquidity to other investors. Research in this area is currently evolving into a broader...

We use the Cox process (or a doubly stochastic Poisson process) to model the claim arrival process for catastrophic events. The shot noise process is used for the claim intensity function within the Cox process. The Cox process with shot noise intensity is examined by piecewise deterministic...

The paper identifies a number of misconceptions about the monetary policy process and the monetary transmission mechanism in the UK. Among the misconceptions about the process are the alleged lack of regional and sectoral representativeness of the Monetary Policy Committee and the view that...

Emerging-market countries are being urged to choose between freely floating exchange rates and firmly fixed rates supported by strong institutional arrangementsûcurrency boards, monetary unions, or formal dollarization. This paper assesses the benefits and costs of institutionalizing fixed...

Microeconomic efficiency and market transparency argue in favour of UK membership in EMU and for Scotland''s membership in the UK monetary union and also in EMU. UK seigniorage (government revenues from money issuance) would be boosted by EMU membership. Lender of last resort arrangements would...

The paper investigates the impact of financial integration on asset return, risk diversification and breadth of financial markets. We analyse a three-country macroeconomic model in which (i) the number of financial assets is endogenous; (ii) assets are imperfect substitutes; (iii) cross-border...

The aim of this paper is to construct theoretical models which help to shed light on the recent criticisms of volatile investment flows. We do not make any empirical attempt to establish the exisitence or gauge the importance of the adverse affects of flows in recent exchange rate crises....

Linear parabolic partial differential equations (PDE’s) and diffusion models are closely linked through the celebrated Feynman-Kac representation of solutions to PDE’s. In asset pricing theory, this leads to the representation of derivative prices as solutions to PDE’s. We give a number of...

In this paper we propose an estimation method for two classes of semiparametric scalar diffusion models driven by a Brownian motion: In the first class, only the diffusion term is parameterised while the drift is unspecified; in the second, the drift term is specified while the diffusion term is...

We propose a semiparametric single-factor diffusion model for the term structure of interest rate. The This model is highly flexible and encompasses most parametric single-factor models proposed in the literature. We fit the semiparametric model to a proxy of the Eurodollar short term interst...
