Promoting competition and protecting customers? Regulation of the GB retail energy market 2008–2016

Journal of Regulatory Economics - In 1999 the GB retail energy market was open to competition for residential customers. In 2008 Ofgem began a series of regulatory interventions, notably a...     

Charleston's newfound “entertainment zone”: should we be concerned?

This CIT Research Letter addresses issues related to the night-time economy and the rapid proliferation of bars along a section of a tourism oriented city's main street. Merely 10 years ago, locals did not frequent the area, it was of no interest to tourists, and it was regarded as a neighbourhood where one would not want to walk, especially at night. However, with the area's transformation to the nightlife centre of the city, issues have arisen that are of concern to city government officials. This paper considers these concerns.     

Timing Equilibria in an Urban Model with Congestion

All spatial urban models with congestion assume that the departure (arrival) time of commutes is exogenously determined and assume that travel speed at a given time and location depends upon the traffic density at that point in time and space. This paper presents a framework that encompasses such models, but allows workers to choose the time at which they leave home (arrive at work). This paper then proves that in general only one equilibrium exists for urban models with traditional congestion technology: a commuting pattern in which commuting is continuous and the rush hour never ends, which is unrepresentative of traffic patterns anywhere. This paper concludes by discussing alternative general equilibrium urban models with congestion that may have more realistic equilibria.     

Supply and demand of policy indicators

The aim of this article is to question the idea that all professional service organizations are undergoing a process of inter-archetype transformation. This idea, originating in organizational archetype theory, is now being used to interpret contemporary processes of change in British and other public sector services. Drawing on an example of management UK restructuring in social services during the 1990s – that of local authority social services in the UK – two main problems with this thesis are identified. First, this service demonstrates that ‘radical’ change has not occurred and that older professional values and working practices persist. Second, it reveals how, in at least one part of the public sector in the UK, management reforms have been partly undermined by a specific constellation of institutions and practices. These observations call for questioning the proposition that inter-archetype change is what has occurred and that current reforms will inevitably have this sort of transformational effect.     

Leadership for Collaboration

Abstract

‘Leadership’ and ‘collaboration’ are integral to twenty-first century governance and management but, despite a growing literature, understanding about leadership for collaboration is hampered by a lack of specificity and nuance in theory and empirical research. This article responds to these limitations by working within an interpretive framework and employing Q-method to uncover different interpretations of leadership for collaboration operant among public managers in Wales. The article uses the concept of situated agency to explain why public managers offer diverse interpretations of leadership for collaboration despite working within the same governance framework, and to identify challenges to public managers in determining appropriate leadership for collaboration.     

COEFFICIENT CHANGE,PRICE EFFECTS,AND IMPLICIT ELASTICITIES: ESTIMATING MICROECONOMIC DETERMINANTS OVER TWO TIME PERIODS

This paper presents and estimates an input–output model in which input coefficient changes are functions of changing prices. The model produces results that mirror the characteristics of input demand functions based on the model of cost minimization subject to producing a desired level of output. It does not rely on the specification of a functional form for input coefficients, and it does not require the use of assumptions regarding the elasticity of substitution. Instead, it allows the actual price and coefficient changes that occur between periods to identify the implicit elasticities and own- and cross-price derivatives. Using this model, it is shown how accurate measures of price effects, including the full array of own and cross-elasticities of demand, can be estimated for models comprising up to 15 sectors given data for only two time periods.     

The Macroeconomic Consequences of Financing Health Insurance

Employer-financed health insurance systems like those used in the United States distort firms’ labor demand and adversely affect the economy. Since such costs vary with employment rather than hours worked, firms have an incentive to increase output by increasing worker hours rather than employment. Given that the returns to employment exceed the returns to hours worked, this results in lower levels of employment and output. In this paper, we construct a heterogeneous agent general equilibrium model where individuals differ with respect to their productivity and employment opportunities. Calibrating the model to the U.S. economy, we generate steady state results for several alternative models for financing health insurance: one in which health insurance is financed primarily through employer contributions that vary with employment, a second where insurance is funded through a non-distortionary, lump-sum tax, and a third where insurance is funded by a payroll tax. We measure the effects of each of the alternatives on output, employment, hours worked, and wages.     

TO ADMIT OR NOT TO ADMIT: THE QUESTION OF RESEARCH PARK SIZE

A theoretical model is used to explore the determinants of the optimum size of a private research park and the effect of university affiliation on that optimum size. Parks are assumed to operate as cooperatives where costs are equally shared among the member firms, and optimality occurs when the firms’ average net benefits are maximized. To achieve this, existing members of a park will limit the park's size, denying entry to firms who wish to join and are willing to share the costs. University affiliation may either increase or decrease the optimum size of a park.
