In this paper we introduce a decomposition of the joint distribution of price changes of assets recorded trade-by-trade. Our decomposition means that we can model the dynamics of price changes using quite simple and interpretable models which are easily extended in a great number of directions,...

In this paper we present a new model for pricing and hedging a portfolio of derivatives that takes into account the effect of an extreme movement in the underlying. We make no assumptions about the timing of this 'crash' or the probability distribution of its size, except that we put an upper...

In this brief note we review some of our recent results on the use of high frequency financial data to estimate objects like integrated variance in stochastic volatility models. Interesting issues include multipower variation, jumps and market microstructure effects.

Researchers commonly assume that business groups, a ubiquitous organizational form in emerging markets, permit affiliated firms to share risk by smoothing income flows and by reallocating money from one affiliate to another in times of distress. This view has received support in the literature...

This paper investigates the governance structure choices of firms when there is competition between legal systems. We study the impact of the allocation of control over choice of governance and reincorporation on firms’ technologies and technological specialization of countries in the...

This paper investigates the incentives of investors to set up an actively managed fund in an emerging market or asset class. The analysis highlights the role of agency problems between fund managers and investors in determining this entry decision. It is shown that investors may wish to set up a...

We report on a technique based on multi-agent games which has potential use in the prediction of future movements of financial time-series. A third-party game is trained on a black-box time-series, and is then run into the future to extract next-step and multi-step predictions. In addition to...

This paper first extends the canonical General Equilibrium with Incomplete Markets (GEI) model with money and default to allow for competitive banking and financial instability. Second, it introduces capital requirements for the banking sector to assess the short and medium term macroeconomic...

Many institutional changes have taken place to payments systems. Indeed, they have been in continual change ever since money first emerged as the dominant technology for conducting transactions. Means of settlement between banks have changed: cheques replaced cash in many transactions, and they...

This paper extends the model proposed by Goodhart, Sunirand, and Tsomocos (2003,2004a, b) to an infinite horizon setting. Thus, we are able to assess how the model conforms with the time series data of the U.K. banking system. We conclude that, since the model performs satisfactorily, it can be...
