Measuring the competitiveness of the UK construction industry. Volume 1

EBS’s estimates of relative productivity in construction are as follows: 1. The US is about 25-35% ahead of the UK and Germany in terms of average labour productivity (ALP). 2. The UK is ahead of Germany in ALP on an output per worker basis, but not on an output per hour worked basis (this is due to Germans working fewer hours per week on average). These results are largely unchanged under various sensitivity tests, for example, using GDP PPP exchange rates instead of construction PPP exchange rates to convert national currencies to a common currency. The EBS estimate for the US-UK comparison is supported by UCL/DL (who estimate a US lead in ALP of 42% in 1999). UCL/DL’s estimates for the Germany-UK comparison are also similar to those of EBS, since they show Germany level with the UK in ALP on an output per worker basis, but ahead on an output per hour worked basis. Productivity comparisons of the UK with France are subject to difficulties. Depending on the exchange rates they use for conversion purposes, EBS find that France is well ahead of Britain on some measures of ALP (and indeed is close to the US) but on other measures French ALP is much the same as in Britain. UCL/DL argue strongly for using an exchange rate, which shows French construction ALP to be well ahead of the UK. They state that: ‘The French construction PPPs have been controversial for some time….[and tend to lead to] underestimates of French construction output’. There are difficulties in conducting this type of analysis that are hard to surmount, for example it is unlikely that labour inputs are well measured in any country because of illegal immigration, ‘ the hidden economy’, etc. However, unless there is reason to think that the proportion of uncounted construction workers is significantly higher or lower in Britain as compared to, say, the United States, then it seems reasonable to accept that ALP in the US construction industry is some way ahead of the UK. In many ways cross-country comparisons of productivity levels across the whole construction industry are not comparing like with like since the composition of construction output differs greatly from country to country. It is therefore hard to construct reliable national rankings based on aggregated data for construction given the present state of the data

GINI DP 15: Can higher employment levels bring down poverty in the EU?

At the European level and in most EU member states, higher employment levels are seen as key to better poverty outcomes. But what can we expect the actual impact to be? Up until now shift-share analysis has been used to estimate the impact of rising employment on relative income poverty. This method has serious limitations. We propose a more sophisticated simulation model that builds on regression based estimates of employment probabilities and wages. We use this model to estimate the impact on relative income poverty of moving towards the Europe 2020 target of 75 percent of the working aged population in work. Two sensitivity checks are included: giving priority in job allocation to jobless households and imputing low instead of estimated wages. This article shows that employment growth does not necessarily result in lower relative poverty shares, a result that is largely consistent with observed outcomes over the past decade.

Trade credit in the UK construction industry: an empirical analysis of construction contractor financial positioning and performance

Research commissioned by the Department for Business, Innovation & Skills (BIS) to inform analysis for the ‘Industrial Strategy for Construction’. It explores the availability of trade credit for UK construction firms and how they rely upon it to support their operations. It looks at: - how companies in the construction sector finance their work - how finance structures within the construction sector compare to those of the economy as a whole - how the way construction companies fund themselves differs between main contractors and subcontractors, and by size of firm - whether the structure of construction industry finance significantly altered since the financial and banking crisis It makes recommendations on the implications of these findings for companies in the construction sector

A Comparison Of Two Ways Of Applying Transaction Costs Approach(I): Methodological Debates

Whilst the importance of transaction costs in construction has been accorded pervasive recognition, the methodologies used to apply this concept to the analysis of the construction process have been divergent. One way starts from searching for quantifiable items of transaction costs and explores the link between these costs and procurement routes. This paper claims that the attempt to provide explanatory foundation for construction procurement behaviour by quantitatively measuring each important element of transaction costs in the construction process is highly unlikely to succeed, since the majority of costs with comparative importance are fairly difficult, if not impossible, to estimate. A possible way to avoid thi s pi t f al l i s t o f ol l ow Wi l l i amson’ s met hodol ogy of c omparative institutional analysis. In this context, we take this to involve operationalising the theory by predicting , for transactions with defined attributes, ordinal differences in transaction costs between inst i t ut i ons ( pr oc ur ement r out es) , and t hus, under a ‘ weak’ profit maximising assumption, to derive and test refutable hypotheses concerning the probability or relative frequency of use of each route

Cost and value ratios of operating renewed English secondary schools

The relative cost ratios of facility construction and operations, and the value generated from building use have been much debated in recent years. Relative values of these ratios are likely different between alternative facility types. Empirical analyses of ratio estimates are presented for English secondary schools over recent years. Findings challenge established views of the relative cost ratios of 1 (construction), 5 (facility management) to 200 (operations or staff), suggesting the ratios are actually 1/1/5 respectively. The study also estimates the value of investing in schools in terms of improved outcomes, applying educational attainment data for rebuilt schools. These are converted into monetary values using wage uplift indicators. This produces estimates of expected economic benefits (increased productivity and output) and benefits to government via future tax receipts (financial return). Findings suggest the present value of future tax revenues alone do justify investing in school rebuilding. Average economic returns are positive but highly variable, with high dispersion in expected benefits. These benefits are positive only in half the rebuilt schools. The results will help inform allocation of public resources in schools, while also assisting management of the growing independent and semi-autonomous school estate

To what extent do fiscal regimes equalize opportunities for income acquisition among citizens?.

This paper employs the theory of equality of opportunity, described in Roemer’s book (Equality of Opportunity, Harvard University Press, 1998), to compute the extent to which tax-and-transfer regimes in 11 countries equalize opportunities among citizens for income acquisition. Roughly speaking, equality of opportunity for incomes has been achieved in a country when it is the case that the distributions of post-fisc income are the same for different types of citizen, where a citizen’s type is defined by the socio-economic status of his parents. Intuitively, a country will have equalized opportunity if the chances of earning high (or low) income are equal for citizens from all family backgrounds. Of course, pre-fisc income distributions, by type, will not be identical, as long as the educational system does not entirely make up for the disadvantage that children, who come from poor families face, but the tax-and-transfer system can play a role in rectifying that inequality. We include, in our computation, two numbers that summarize the extent to which each country’s current fiscal regime achieves equalization of opportunities for income, and the deadweight loss that would be incurred by moving to the regime that does.Fiscal regimes; Equal opportunities; Income acquisition;

Inequalities' Impacts: State of the Art Review

By way of introduction This report provides the fi rm foundation for anchoring the research that will be performed by the GINI project. It subsequently considers the fi elds covered by each of the main work packages: ● inequalities of income, wealth and education, ● social impacts, ● political and cultural impacts, and ● policy effects on and of inequality. Though extensive this review does not pretend to be exhaustive. The review may be “light” in some respects and can be expanded when the analysis evolves. In each of the four fi elds a signifi cant number of discussion papers will be produced, in total well over 100. These will add to the state of the art while also covering new round and generating results that will be incorporated in the Analysis Reports to be prepared for the work packages. In that sense, the current review provides the starting point. At the same time, the existing body of knowledge is broader or deeper depending on the particular fi eld and its tradition of research. The very motivation of GINI’s focused study of the impacts of inequalities is that a systematic study is lacking and relatively little is known about those impacts. This also holds for the complex collection of, the effects that inequality can have on policy making and the contributions that policies can make to mitigating inequalities but also to enhancing them. By contrast, analyses of inequality itself are many, not least because there is a wide array of inequalities; inequalities have become more easily studied comparatively and much of that analysis has a signifi cant descriptive fl avour that includes an extensive discussion of measurement issues. @GINI hopes to go beyond that and cover the impacts of inequalities at the same time

To what extent do fiscal regimes equalize opportunities for income acquisition among citizens?

This project employs the theory of equality of opportunity, described in Roemer’s book (Equality of Opportunity, Harvard University Press, 1998), to compute the extent to which tax-and-transfer regimes in ten countries equalize opportunities among citizens for income acquisition. Roughly speaking, equality of opportunity for incomes has been achieved in a country when it is the case that the distributions of post-fisc income are the same for different types of citizen, where a citizen's type is defined by the socioeconomic status of his parents. Intuitively, a country will have equalized opportunity if the chances of earning high (or low) income are equal for citizens from all family backgrounds. Of course, pre-fisc income distributions, by type, will not be identical, as long as the educational system does not entirely make up for the disadvantage that children, who come from poor families face, but the tax-and-transfer system can play a role in rectifying that inequality. We include, in our computation, two numbers that summarize the extent to which each country’s current fiscal regime achieves equalization of opportunities for income, and the deadweight loss that would be incurred by moving to the regime that does

Screen-based identification and validation of four new ion channels as regulators of renal ciliogenesis

©2015. To investigate the contribution of ion channels to ciliogenesis, we carried out a small interfering RNA (siRNA)-based reverse genetics screen of all ion channels in the mouse genome in murine inner medullary collecting duct kidney cells. This screen revealed four candidate ion channel genes: Kcnq1, Kcnj10, Kcnf1 and Clcn4. We show that these four ion channels localize to renal tubules, specifically to the base of primary cilia. We report that human KCNQ1 Long QT syndrome disease alleles regulate renal ciliogenesis; KCNQ1-p. R518X, -p.A178T and -p.K362R could not rescue ciliogenesis after Kcnq1-siRNA-mediated depletion in contrast to wild-type KCNQ1 and benign KCNQ1-p.R518Q, suggesting that the ion channel function of KCNQ1 regulates ciliogenesis. In contrast, we demonstrate that the ion channel function ofKCNJ10 is independent of its effect on ciliogenesis. Our data suggest that these four ion channels regulate renal ciliogenesis through the periciliary diffusion barrier or the ciliary pocket, with potential implication as genetic contributors to ciliopathy pathophysiology. The new functional roles of a subset of ion channels provide new insights into the disease pathogenesis of channelopathies, which might suggest future therapeutic approaches
