Working papers

In this paper we model the changing distribution of household spending in the UK over the period 1978 to 1999 and explore the interpretation of remaining time trends in spending once changes in other observed covariates have been accounted for.

We develop inference tools in a semiparametric partially linear regression model with missing response data.

In December 2001, the TLRC established a working party under the Chairmanship of Sir Alan Budd. The Working Party's terms of reference were Ӕo review the institutional processes for the Parliamentary scrutiny of tax proposals and for the enactment of tax legislation and to consider whether changes to those processes would promote simplification and improve the quality of tax legislation and, if so, what the nature of those institutional changes should be.Ԡ This Reports sets out the working party's conclusions.

This paper evaluates the effects of a mjor educational reform in Sweden.

We suggest two nonparametric approaches, based on kernel methods and orthogonal series, respectively, to estimating regression functions in the presence of instrumental variables.

In this paper we show that the sharp RDD straightforwardly generalizes to the instances in which the eligibility for the program is established with respect to an observable pre-program measure with eligible individuals self-selecting into the treatment group according to an unknown process.

This paper reviews how the impact of taxes on the incentive to invest in the corporate sector can be measured. The main focus of the paper is to discuss measures derived from economic theory.

This paper explores the properties of alternative measures of the taxation of income from capital, by applying them to data for the UK over the last thirty years.

We examine the role of ill-health in retirement decisions in Britain, using the first eight waves of the British Household Panel Survey (1991-98).

We propose a procedure for estimating the critical values of the extended Kolmogorov-

This paper investigates whether there is a convergence in Total Factor Productivity towards the technological frontier at the establishment level.

This paper reviews the record of randomized field trials in welfare reform and assesses the implications of that record for the use of randomization.

This paper explores the identifiability of ratios of derivatives of the index function in a model of a duration process in which the impact of covariates on the hazard function passes through a single index.

We provide easy to verify suffcient conditions for the consistency and asymptotic normality

This paper tests the published section level price and weight dataused in the compilation of the UK Retail Prices Index for consistencywith the theory of the cost-of-living index.

Four alternative but related approaches to empirical evaluation of policy interventions are studied.

This paper studies the estimation of conditional quantiles of counts.
