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...

Complex interactions between fundamentals and liquidity during unstable periods in financial markets are succinctly modeled with coordination games. We propose a flexible framework to estimate such a model and use the efficient method of moments as estimation procedure. We illustrate the model...

The exponential growth of hedge funds, their role in financial crises in the 1990s, and examples of fraudulent behaviour have precipitated a heated debate over their regulatory status. The existing approaches of greater disclosure and activity restrictions appear too blunt to be effective and...

Order flow has been found to carry information to the market. When assessing how informative order flow is, the VAR methodology is typically employed, using impulse response functions. However, in such analyses, the direction of causality runs explicitly from order flow to asset return. If data...

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...

This paper explores the potential for violations of VaR subadditivity both theoretically and by simulations, and finds that for most practical applications VaR is subadditive. Hence, there is no reason to choose a more complicated risk measure than VaR, solely for reasons of coherence.

The experience from the global financial crisis has raised serious concerns about the accuracy of standard risk measures as tools for the quantification of extreme downward risk. A key reason for this is that risk measures are subject to model risk due, e.g., to specification and estimation...
