I have been interested for a few years in the idea that Antonio, the eponymous Merchant of Venice, is the personification of agape , Christian love, in Shakespeare's play.  While the argument I offer here in the week before Christmas has its basis in Christ...

I recently attended the Alan Turing Institute summit on Data Analytics for Credit Risk  and left wondering if statistics is well placed to address the problems of big data and if there were skills in the humanities that were more appropriate.  It also lead ...

A moral case for bank money
Finance is a skeleton that supports the development of a healthy society, not a utility that plumbs the economy together. The justification for this observation is historical. Richard Seaford has  argued  that the culture that emerged in Greece some two and...

This simple saying highlights the inter-subjective nature of markets,

The problem of voluntary slavery for utilitarianism
Reciprocity is a norm , a rule embedded in financial mathematics,
which permits high rates of interest to poorer, higher risk,
borrowers. This means that phenomena such as debt-bondage can become
prevalent (von Lilienfeld-Toal and Mookherjee, 2010). Volunta...

Building real markets for the good of the people
The Bank of England is seeking to build an 'Open Forum' Building real markets for the good of the people . I am participating in this forum and here I seek to address the questions Are reforms creating the soft and hard infrastructure to ensure FICC market...
In summary I believe the reforms focus on specific actions but do not address fundamental issues around how markets are perceived. This reflects the Bank's desire to deliver concrete proposals to solve a range of specific problems. The risk is that the reforms tackle situations already ...

Mathiness: not just a problem of macro-economics
I was aware of the "mathiness" discussion initiated by the macro-economist Paul Romer, but have only read the articles because while the discussion was taking place I was finishing of an article for The Mathematical Intelligencer that presents a remarkably ...

Story
Introduction
I am a Lecturer in Financial Mathematics at Heriot-Watt University in Edinburgh.  Heriot-Watt was the first UK university to offer degrees in Actuarial Science and Financial Mathematics and is a leading UK research centre in the fields.  

Between 2006-2011 I was the UK Research Council's Academic Fellow in Financial Mathematics and was involved in informing policy makers of mathematical aspects of the Credit Crisis.
