This paper analyses the real economy effects of firms having some shareholders with a short investment horizon on their shareholder register.  Short-term shareholders cause management to be concerned with the path of the share price as well as its ultimate value.  Such shareholders in an...

This paper undertakes an empirical analysis of the effects of the threat of takeover on company performance, based on a panel of 643 nonfinancial quoted UK companies over the period 1989-96. Our measure of the intensity of the threat of takeover is the predicted probability of takeover estimated...

We identify a natural way of ordering functions, which we call the interval dominance order and develop a theory of monotone comparative statistics based on this order.  This way of ordering functions is weaker than the standard one based on the single crossing property (Milgrom and Shannon,...

This paper presents a model of a rational seller who is actively learning the slope of his demand curve via his pricing strategy.  Consequently, this seller optimally experiments with his price.  Resulting price patterns show a lot of discreteness (as observed in the data), which has proved to...

We present a continous time non tatonnement process for frictionless and perfectly competitive markets with (possibly non convex) production, where the natural rate of unemployment (NRU) emerges as the asymptotic value of unemployment.  Consumers and producers are myopic and repeatedly...

Suppose we observe a finite number of input decisions made by a firm, as well as the prices at which those inputs were acquired.  What conditions on the set of observations are necessary and sufficient for it to be consistent with a firm choosing inputs to maximize profit, subject to a...

In this paper it is argued that the terms, knowledge work, knowledge workers, and <p> knowledge intensive firms point to emerging social structures and processes in <p> organisations. This focus allows us to analyse organisations in ways that differ <p> from the notions involving less dynamic forms of...</p></p></p>

These are additional notes relating to the paper `The Comparative Statics of Constrained Optimization Problems`, which is appearing in Econometrica. It gathers together material present in various earlier versions of the paper, as well as some new material, which are not found in the published...

It is often taken as axiomatic that investors prefer high levels of regulation.  Yet companies have increasingly chosen to list on stock exchanges with lower regulatory requirements.  In this paper we analyse whether investors value high regulatory standards for quoted companies.  We use the...
