We evaluate the relationship between competition and innovation in an industry where production is polluting and R&D has the aim to reduce emissions. We build up an oligopoly model where n firms compete in quantities and decide their investment in green R&D. When environmental taxation is...

We examine the impact of housing wealth on labour supply using exogenous local variations in house prices and household panel data for Britain. Our analysis controls for variations in local labour demand and income expectations which might co-determine house prices and labour supply. We find...

A new estimator of bid-ask spreads is presented. When the trade direction is known, any estimate of the spread is associated with a unique series of conjectural mid-prices derived by adjusting the observed transaction price by half the estimated spread. It is shown that the covariance of...

It is shown that, with fixed transaction costs in the market for risky assets, investors with wealth below a certain threshold will hold pooled index funds that charge a proportional fee, rather than the market portfolio chosen by wealthier investors. If a portfolio of closed-end index funds...

We investigate monthly bilateral exchange rate volatility for a large sample of currency pairs over the period 1999-2006. Pegs (particularly to the US dollar) and managed floats tend to have lower volatility than independent floats. A deeper investigation shows that the peg effect operates...

Recent years have seen revived interest in the role of monopsony power in wage-setting in the public sector. Most evidence focuses on individual occupations rather than considering the implications for wage and employment structure where the state has differential monopsony power across...

We present two experiments designed to investigate whether individuals’ notions of distributive justice are associated with their relative (within-society) economic status. Each participant played a specially designed four-person dictator game under one of two treatments, under one initial...

It is well known that the competing risks model is identified if the dependence structure between risks (the copula function) is known or assumed. Special cases include independence of risks or independent censoring. If the copula function is not specified, parameters of interest are only set...
