We examine trends in wage inequality in the US and other countries over the past four decades. We show that there has been a secular increase in the 90-50 wage differential in the US and the UK since the late 1970s. By contrast the 50-10 differential rose mainly in the 1980s and flattened or...

Labor’s share of GDP in most OECD countries has declined over the last two decades. Some authors have suggested that these changes are linked to deregulation of product and labor markets. To examine this we focus on a large quasi-experiment in the OECD: the privatization of many network...

Linear parabolic partial differential equations (PDE’s) and diffusion models are closely linked through the celebrated Feynman-Kac representation of solutions to PDE’s. In asset pricing theory, this leads to the representation of derivative prices as solutions to PDE’s. We give a number of...

We propose a semiparametric single-factor diffusion model for the term structure of interest rate. The This model is highly flexible and encompasses most parametric single-factor models proposed in the literature. We fit the semiparametric model to a proxy of the Eurodollar short term interst...

We analyse the role of financial sector workers in the huge rise of the share of earnings going to those at the very top of the pay distribution in the UK. Rising bankers' bonuses accounted for two-thirds of the increase in the share of the top 1% after 1999. Surprisingly, bankers' share of...

In this paper we propose an estimation method for two classes of semiparametric scalar diffusion models driven by a Brownian motion: In the first class, only the diffusion term is parameterised while the drift is unspecified; in the second, the drift term is specified while the diffusion term is...
