a column by Federico Diez, Jiayue Fan and Carolina Villegas-Sanchez for VOX: CEPR’s Policy Portal
Studies of the evolution of market power since 2000 have focused mostly on publicly traded US firms.
This column introduces a new global study that incorporates private firms, and decomposes the aggregate effect into intensive and extensive margins. It shows the increase in markup is broad-based across countries and sectors, but is driven by a small number of firms. The markup increase is mainly explained by increases in the average markup of incumbents, and reallocation effects towards new firms that gain market share from incumbents.

Monopsony in the UK
a column by Will Abel, Silvana Tenreyro and Gregory Thwaites for VOX: CEPR’s Policy Portal
Concentrated labour markets, in which workers have few choices of potential employers, reduce the wages of workers when they are not covered by collective wage bargaining agreements.
But these types of agreements have become much less common in the past 20 years.
This column uses employee-level data to show that even though UK labour markets have not on average become much more concentrated, concentration – which varies a great deal across regions and industries – is having a bigger impact on wages than before.

a post by Margarita Tartakovsky for the World of Psychology blog
Most people know the telltale signs of depression: a deep, sinking sadness, loss of hope, a bleak outlook on life, and weight and appetite changes. As psychologist Deborah Serani, Psy.D, said, most people also picture a slow-moving individual with sloped shoulders who’s unable to get out of bed.
While for some people the above is absolutely true, for others, different signs are more prominent and indicative of depression – signs that might surprise you. Below are six symptoms to watch out for.

Spatially Concentrated Deprivation in England: An Empirical Assessment
an article by Alasdair Rae (Department of Town and Regional Planning, University of Sheffield, UK) published in Regional Studies
Volume 46 Issue 9 (2012)
Abstract
Spatially concentrated deprivation is a well-documented phenomenon and is of interest to a diverse constituency of academics and policy-makers.
Despite the accepted view of concentrated deprivation as a problem, however, the empirical basis for understanding it remains under-developed. Therefore, an attempt is made here to provide an empirical assessment of spatially concentrated deprivation in England using spatial statistics and a policy-relevant deprivation measure.
More localized analyses are also conducted for London, Birmingham, Liverpool and Manchester.
The results demonstrate that deprivation in England is highly concentrated, that it varies significantly over space and that spatial patterns persist through time.
JEL classifications: J, J0, J4, J6, J40, J60, J64
