We quantify the amount of information filtered by different hierarchical clustering methods on correlations between stock returns comparing the clustering structure with the underlying industrial activity classification. We apply, for the first time to financial data, a novel hierarchical...

The paper examines recent evidence on the erosion of the German industrial relations model. Although its coverage has declined, much of this has occurred in smaller and newer establishments, and compared with Britain, it has remained solid in the areas of Germany's traditional industrial...

This article considers how the 'accidental logics' of political settlements for the English National Health Service (NHS) and the Medicare and Medicaid programmes in the United States have resulted in different institutional arrangements and different implicit social contracts for rationing,...

In a panel data model with fixed effects, possible cross-sectional dependence is investigated in a spatial autoregressive setting. An Edgeworth expansion is developed for the maximum likelihood estimate of the spatial correlation coefficient. The expansion is used to develop more accurate...

Nonparametric regression is developed for data with both a temporal and a cross-sectional dimension. The model includes additive, unknown, individual-specific components and allows also for cross-sectional and temporal dependence and conditional heteroscedasticity. A simple nonparametric...

This paper argues that there is nothing anomalous about the flypaper effect. I develop a simple median voter model of government spending with costly tax collection that predicts the flypaper effect and provide a quantifiable measure of its magnitude. Using the model insights and previous...

Background: Evidence suggests a much higher prevalence of postpartum depression in South Asia than in ‘western’ contexts. Aim: To conduct a rapid systematic review of evidence on the association between social relationships and postpartum depression in South Asia. Methods: Five databases...

The latest CEP Election Analysis gives an overview of the research evidence on education policy, one of the key battlegrounds of the 2010 General Election.

We investigate the causal relationship between judicial efficiency and firm size across Italian municipalities, exploiting spatial discontinuities in tribunals' jurisdiction for identification. Results show that halving the length of civil proceedings, average firm size would increase by around...
