The prospects are considered of deploying batteries and fuel cells in order to reduce the carbon emissions from various modes of transport. It is proposed that the government has not done enough to advance these technologies and that Britain is lagging behind other countries. The adequacy of Britain’s future supplies of energy is called into question.

The development of postal services has played an indisputable role in industrialization, market integration and state formation. Smooth functioning of these services depended on the existence of a well-paid and motivated body of civil servants. I study the organization of the internal labour market for civil servants in postal services in Spain from 1890 to 1935 showing a career in the postal services offered high entry wages, growing wages over the life cycle, and a secure job until retirement. There were two downsides to pursuing a career in the postal services. Firstly, entry and promotion depended on the expansion of employment. Secondly, nominal wages were upward rigid, causing large real wage losses during WWI.

In the 1940s, when the governor of Puerto Rico was still appointed by the U.S. president, a large state-owned enterprise (SOE) sector was established. Later, in 1948-1950, the island's first elected government privatised these SOEs. This paper documents both the creation of the SOE sector and its privatisation, and analyses the role played by ideology, political interests and economic concerns in the decision to privatise. Whereas ideological factors might have played a significant role in the building of the SOE sector, the privatisation process was driven by economic factors. In the cement sector, the competing private firm was more efficient and the SOEs in other sectors with no private competitors in the island showed permanent losses.

We consider the measurement of performance in the public sector in general, focussing on local government and the provision of library services by English local authorities in particular. We will consider two methodologies that assess the performance of local authorities in terms of the efficiency with which they provide services and consider methods that allow us to account for exogenous influences on performance, such as the socio-economic profile of the population served by the authority. We find that although both methods' results appear similar, the implications for potential cost savings vary widely. Omitting to account for background factors leads to an overstatement of the level of inefficiency and hence the scope for reducing expenditure.
