This paper proposes a measure of financial fragility that is based on economic welfare in a general equilbrium model calibrated against UK data. The model comprises a household sector, three active heterogeneous banks, a central bank/regulator, incomplete markets, and endogenous default. We...

The aim of this paper is to examine the pros and cons of book and fair value accounting from the perspective of the theory of banking. We consider the implications of the two accounting methods in an overlapping generations environment. As observed by Allen and Gale(1997), in an overlapping...

This paper orders option prices under various well known martingale measures in an incomplete stochastic volatility model. The central result is a comparison theorem which proves convex option prices are decreasing in the market price of volatility risk, the parameter governing the choice of...

This paper investigates the relation between stock liquidity and firm performance. We find that firms with liquid stocks have better firm performance as measured by the market-to-book ratio. This result holds even when we include industry or firm fixed effects, control for idiosyncratic risk,...

GARCH models are commonly used as latent processes in econometrics, financial economics and macroeconomics. Yet no exact likelihood analysis of these models has been provided so far. In this paper we outline the issues and suggest a Markov chain Monte Carlo algorithm which allows the calculation...

We study the implications of conformism among analysts in a CARA Gaussian model of the market for a risky asset, where a trader's in- formation is a message sent by an analyst. Conformism increases the weight of the public information in the messages, decreasing their in- formativeness. More...

We study price formation in securities markets, using the sequential trade framework of Glosten and Milgrom. This paper makes one basic methodological advance over previous research on sequential securities trading: we allow traders to choose from n trade sizes in a multi-period market, where n...

We present a model for Financial fragility in which banks are risk-averse portfolio managers and there is uncertainty over risk management parameters. There is a danger of heightened risk aversion and projects in small economies are assumed to be riskier than those in large economies. In this...

This paper is concerned with the Bayesian estimation of non-linear stochastic differential equations when observations are discretely sampled. The estimation framework relies on the introduction of latent auxiliary data to complete the missing diffusion between each pair of measurements. Tuned...

We investigate the optimal regulation of financial conglomerates which combine a bank and a non-bank financial institution. The conglomerate’s risk-taking incentives depend upon the level of market discipline it faces, which in turn is determined by the conglomerate’s liability...
