Partial mean processes with generated regressors arise in several important econometric problems, such as the distribution of potential outcomes with continuous treatments and the quantile structural function in a nonseparable triangular model.  This paper proposes a fully nonparametric...

In real-life, individuals are often assigned to binary treatments according to existing treatment protocols.  Such protocols, when designed with “taste-based†motives, would be productively inefficient in that the expected returns to treatment for the marginal treatment recipient...

This study analyses behaviour of women community based organisations in two districts in Nepal in reducing prevalence of child malnutrition in member households. Our survey focused on three sets of women organisations: those that receive intensive external support are compared with those that...

Functional Signal plus Noise (FSN) time series models are introduced for the econometric analysis of the dynamics of a large cross-section of prices in which contemporaneous observations are functionally related. A semiparametric FSN model is developed in which a smooth, cubic spline signal...

Functional Signal plus Noise (FSN) models are proposed for analysing the dynamics of a large cross-section of yields or asset prices in which contemporaneous observations are functionally related. The FSN models are used to forecast high dimensional yield curves for US Treasury bonds at the one...

Time invariance of factor loadings is a standard assumption in the analysis of large factor models.  Yet, this assumption may be restrictive unless parameter shifts are mild (i.e., local to zero).  In this paper we develop a new testing procedure to detect big breaks in these loadings at...

The class of Functional Signal plus Noise (FSN) models is introduced that provides a new, general method for modelling and forecasting time series of economic functions.  The underlying, continuous economic function (or 'signal') is a natural cubic spline whose dynamic evolution is driven by a...

British regions display persistent differences in both earnings and unemployment rates. A number of studies have found that in general, regions that have high unemployment tend to have low wages. This runs contrary to a compensating differentials argument that high wages should compensate for...
