Privatisation and cross-border electricity trade: from internal market to European Supergrid?

he perspective European Supergrid would consist of an integrated power system network, where electricity demands from one country could be met by generation from another country. This paper makes use of a bi-linear fixed-effects model to analyse the determinants for trading electricity across borders among 34 countries connected by the European Supergrid. The key question that this paper aims to address is the extent to which the privatisation of European electricity markets has brought about higher cross-border trade of electricity. The analysis makes use of distance, price ratios, gate closure times, size of peaks and aggregate demand as standard determinants. Controlling for other standard determinants, it is concluded that privatisation in most cases led to higher power exchange and that the benefits are more significant where privatisation measures have been in place for a longer period.

Good practice transfer within small construction specialist trade contractors

Government and institutionally-driven ‘good practice transfer’ initiatives are consistently presented as a means to enhance construction firm and industry performance. Two implicit tenets of these initiatives appear to be: knowledge embedded in good practice will transfer automatically; and, the potential of implementing good practice will be capitalised regardless of the context where it is to be used. The validity of these tenets is increasingly being questioned and, concurrently, more nuanced knowledge production understandings are being developed which recognise and incorporate context-specificity. This research contributes to this growing, more critical agenda by examining the actual benefits accrued from good practice transfer from the perspective of a small specialist trade contracting firm. A concept model for successful good practice transfer is developed from a single longitudinal case study within a small heating and plumbing firm. The concept model consists of five key variables: environment, strategy, people, technology, and organisation of work. The key findings challenge the implicit assumptions prevailing in the existing literature and support a contingency approach that argues successful good practice transfer is not just adopting and mechanistically inserting into the firm, but requires addressing ‘behavioural’ aspects. For successful good practice transfer, small specialist trade contracting firms need to develop and operationalise organisation slack, mechanisms for scanning external stimuli and absorbing knowledge. They also need to formulate and communicate client-driven external strategies; to motive and educate people at all levels; to possess internal or accessible complementary skills and knowledge; to have ‘soft focus’ immediate/mid-term benefits at a project level; and, to embed good practice in current work practices.

Equipped to deal with uncertainty in climate and impacts predictions: lessons from internal peer review

The quantification of uncertainty is an increasingly popular topic, with clear importance for climate change policy. However, uncertainty assessments are open to a range of interpretations, each of which may lead to a different policy recommendation. In the EQUIP project researchers from the UK climate modelling, statistical modelling, and impacts communities worked together on ‘end-to-end’ uncertainty assessments of climate change and its impacts. Here, we use an experiment in peer review amongst project members to assess variation in the assessment of uncertainties between EQUIP researchers. We find overall agreement on key sources of uncertainty but a large variation in the assessment of the methods used for uncertainty assessment. Results show that communication aimed at specialists makes the methods used harder to assess. There is also evidence of individual bias, which is partially attributable to disciplinary backgrounds. However, varying views on the methods used to quantify uncertainty did not preclude consensus on the consequential results produced using those methods. Based on our analysis, we make recommendations for developing and presenting statements on climate and its impacts. These include the use of a common uncertainty reporting format in order to make assumptions clear; presentation of results in terms of processes and trade-offs rather than only numerical ranges; and reporting multiple assessments of uncertainty in order to elucidate a more complete picture of impacts and their uncertainties. This in turn implies research should be done by teams of people with a range of backgrounds and time for interaction and discussion, with fewer but more comprehensive outputs in which the range of opinions is recorded.
