Administrative review and oversight: the experience of Westminster

Parliament has been left behind by far-reaching changes to the constitution, government and society in the past two decades. Despite recent innovations, particularly in the handling of legislation, the central question of Westminster's scrutiny of the executive has not been addressed. (Report of the Hansard Society Commission on Parliamentary Scrutiny, 2001: x) Prior to the Labour Party's election victory in 1997, Labour's manifesto promised an 'effective House of Commons' to be realised in large part through the creation of a special Select Committee with remit to review procedures in light of the 'need for modernisation'. Shortly after victory, Labour established a 'Modernisation Committee' chaired by the Leader of the Commons and with a remit to review four key areas: the legislative process; ministerial accountability; working practices (such as sitting hours); and the style and forms of proceedings. Between 1997 and 2003 the Committee published 19 reports starting with a report on the legislative process. However, to date, most of the reports have focused on the modernisation of working practices and the style and form of proceedings. Reports that deal with improving the effectiveness of ministerial accountability have been notably lacking. Consequently, the view of the Hansard Society that 'parliamentary reform has been one of improving the efficiency of Parliament, but not its effectiveness' appears just as valid three years on

Inequality under the Labour government

This Briefing Note will provide a brief analysis of changes to income inequality since the Labour government came to power in 1997.1 The most recent data from 2001-02 show that there has been little change in income inequality since 2000-01. An implication of this is that there has been little impact upon the slight upward trend in inequality that has been experienced over Labour's term in government

The epidemiology of mastitis in Australian dairy cattle : a dissertation submitted in partial fulfilment of the requirements for the degree of Masters of Veterinary Studies (Epidemiology)

This study represents an aggregation of knowledge on mastitis within the Australian dairy industry. Aspects of the epidemiology and economics of mastitis have been collated and areas of missing knowledge identified. A clinical treatment trial was conducted on subclinical mastitis to identify the role of therapy upon subclinical infection. The effect of individual variables on mastitis risk was studied and aggregated in order to facilitate the development of a computer simulation model of mastitis within Australian dairy herds. A literature review of mastitis within the Australian dairy industry was conducted. The economic impact of mastitis was examined and the pathway of economic loss to the dairy industry is discussed. The epidemiology of mastitis was studied with special emphasis on quantification of the effect of individual risk factors on the occurrence of disease. Performance parameters for the current diagnostic tests applied within the dairy industry are presented and their suitability for use in a commercial environment discussed. The impact of self-cure and the efficacy of therapeutic intervention in the disease are examined. The role of culling is presented. The chapter concludes with an estimation of die total economic losses experienced on a commercial dairy farm in Victoria in 1998 for three different mastitis levels. The economic benefit to be gained from a reduction in mastitis is also presented. A clinical treatment trial of subclinically infected cows (high somatic cell count) was conducted in order to determine if therapeutic intervention was an effective management tool. Cows with somatic cell counts in excess of 500,000 cells per ml and more than 14 days calved were selected and randomly assigned to treatment and control groups. A pooled quarter milk sample was taken prior to treatment and repeated at around six weeks after treatment. Treated cows received a course of intramammary and parenteral antibiotics and control cows were untreated. Cows were followed for the rest of the lactation of treatment and into the subsequent lactation and somatic cell counts were recorded. The major pathogens identified were S anreus and S uberis. Treatment did not have a significant or commercially useful effect upon bacteriological cure rates, survival of cows to the next lactation or somatic cell count for the remainder of the lactation. Treatment of high somatic cell count cows during lactation is not recommended and is discussed. A requirement exists for the development of a stochastic simulation model of mastitis within Australian dairy herds. The structure of such a model was developed and is presented. Underlying production and somatic cell count responses in Australian cattle were derived. Infection status variables were included and stochasticity was introduced through the use of control variates. State transition probabilities were collected from the literature. Deficiencies in knowledge were identified and methods for modeling these deficient areas discussed. The aggregated information is presented. It is expected that a working stochastic simulation model of mastitis within Australian dairy herds will be developed from infomation collected in this dissertation

A Nonparametric Bayesian Approach to Copula Estimation

We propose a novel Dirichlet-based P\'olya tree (D-P tree) prior on the copula and based on the D-P tree prior, a nonparametric Bayesian inference procedure. Through theoretical analysis and simulations, we are able to show that the flexibility of the D-P tree prior ensures its consistency in copula estimation, thus able to detect more subtle and complex copula structures than earlier nonparametric Bayesian models, such as a Gaussian copula mixture. Further, the continuity of the imposed D-P tree prior leads to a more favorable smoothing effect in copula estimation over classic frequentist methods, especially with small sets of observations. We also apply our method to the copula prediction between the S\&P 500 index and the IBM stock prices during the 2007-08 financial crisis, finding that D-P tree-based methods enjoy strong robustness and flexibility over classic methods under such irregular market behaviors

Employment, hours of work and the optimal design of earned income tax credits

This paper examines the optimal schedule of marginal tax rates and the design of earned income tax credits. The analysis is based on a structural labour supply model which incorporates unobserved heterogeneity, fixed costs of work and the detailed non-convexities of the tax and transfer system. An analytical framework is developed that allows explicitly for an extensive margin in work choices and also the partial observability of hours of work. This is contrasted to the standard case in which only earnings (and non-labour income) are observable to the government. The empirical motivation is the earned income tax credit reforms in Britain which include a minimum hours requirement at 16 hours per week and a further bonus at 30 hours. Our analysis examines the case for the use of hours-contingent payments and lends support for the overall structure of the British tax credit reforms. However, we also provide a strong case for a further reduction of marginal rates for lower earners but only those with school age children

Has Labour made work pay?

A review of the Labour Government's success in improving the financial reward to work for low-income families. Since 1997, the Labour Government has instigate a series of reforms aimed at helping to make work pay more than not working, and to make work pay enough to help families avoid poverty. This report is the first to provide an overview of all such policies since 1997, and to provide an impartial analysis of the evidence of the Government's success to date. The report examines the key outcomes targeted by 'make work pay' policies, showing trends in the proportion of parents in employment, and the number of children in households where no adult is in paid work. It reviews studies which estimate the contribution that government policies made to these changes. And it provides new evidence on the impact of changes to personal taxes, tax credits and benefits on measures of financial work incentives. The authors also anticipate where this policy agenda might take the Government in the future

Inequality and living standards in Great Britain: some facts

This Briefing Note is designed to provide some basic facts concerning living standards and inequality in Great Britain. Wherever possible, up-to-date sources have been given for further reading. Accompanying this Briefing Note is a spreadsheet of useful statistics relating to the income distribution in Britain. This can be downloaded from the IFS web site at http://www.ifs.org.uk/bns/bn19figs.zip. Both were last updated on 9 March 2004. Section I of this Briefing Note starts by setting out some of the issues and conceptual difficulties surrounding the measuring of living standards and inequality. A picture of the income distribution in Great Britain and many of the important trends in living standards is then presented in the sections that follow. In Sections II and III, we choose weekly before-housing-costs household equivalent income1 as our measure of living standards, as well as presenting some results on an after-housing-costs basis. Section IV then considers using weekly equivalent household expenditure (including housing costs) as a comparative measure of living standards. Section V cites research tracking the income of individuals across a number of years, while Section VI looks at work that attempts to assess how income status changes across generations. Sections VII, VIII and IX proceed by examining some of the factors responsible for the changes in inequality described, looking at the labour market, demographic changes and the impact of taxes and benefits. Section X concludes
