Regulation of herbivore growth by the balance of light and nutrients.

Experiments using planktonic organisms revealed that the balance of radiant energy and available nutrients regulated herbivore growth rates through their effects on abundance and chemical composition of primary producers. Both algae and herbivores were energy limited at low light/nutrient ratios, but both were nutrient limited at high light/nutrient ratios. Herbivore growth increased with increasing light intensity at low values of the light/nutrient ratio due to increases in algal biomass, but growth decreased with increasing light at a high light/nutrient ratio due to decreases in algal quality. Herbivore production therefore was maximal at intermediate levels of the light/nutrient ratio. The results contribute to an understanding of mass transfer mechanisms in ecosystems and illustrate the importance of integration of energy-based and material-based currencies in ecology.

Does EU regulation hinder or stimulate innovation? CEPS Special Report No. 96, 19 November 2014

Introduction. One frequently hears the question posed in the title to this report, but there is little systematic analytical literature on the issue. Fragmented evidence or anecdotes dominate debates among EU regulatory decision-makers and in European business, insofar as there is a genuine debate at all. This CEPS Special Report focuses on the multi-faceted, ambiguous and complex relationship between (EU) regulation and innovation in the economy, and discusses the innovation-enhancing potential of certain regulatory approaches as well as factors that tend to reduce incentives to innovate. It adopts an 'ecosystem' approach to both regulation and innovation, and study the interactions between the two ecosystems. This general analysis and survey are complemented by seven case studies of EU regulation enabling and disabling innovation, two horizontal and five sectoral ones. The case studies are preceded by a broader contextual analysis of trends in EU regulation over the last three decades. These trends show the significant transformation of the nature as well as improvement of the quality of EU regulation, largely in the deepened internal market, which tend to have a favourable and lasting effect on the rate of innovation in the EU (other things being equal). Among the findings include the following: Regulation can at times be a powerful stimulus to innovation. EU regulation matters at all stages of the innovation process. Different types of regulation can be identified in terms of innovation impact: general or horizontal, innovation-specific and sector-specific regulation. More prescriptive regulation tends to hamper innovative activity, whereas the more flexible EU regulation is, the better innovation can be stimulated. Lower compliance and red-tape burdens have a positive effect on innovation. The authors recommend incorporating a specific test on innovation impacts in the ex-ante impact assessment of EU legislation as well as in ex-post evaluation. There is ample potential for fostering innovation by reviewing the EU regulatory acquis.

GATS and the Social Regulation of Services. IES WORKING PAPER 3/2010

Many service transactions are highly complex, and their quality is difficult to ascertain for consumers. In order to have properly functioning service markets, the services thus often require regulation. However, with the advent of the WTO, international trade in services has become increasingly rule-bound. GATS has considerable, intricate effects on social regulation due to the characteristics of services. The allocation of regulatory jurisdiction between home and host country, for example, is rendered difficult by the process-based nature of a lot of services. The WTO US – Gambling dispute settlement report is the first to address GATS disciplines on social regulation in a detailed manner. This working paper submits that the US - Gambling report has increased interference with domestic social regulation and created regulatory uncertainty for WTO members. However, it is also argued that the real impact of the GATS on social regulation can only be understood by looking beyond the text of the GATS. GATS disciplines may become amplified through their interaction with domestic and other international law. The GATS also contains some “political” counterbalancing mechanisms that allow members to renegotiate their commitments. It is argued that these political mechanisms strengthen subsidiarity in the GATS, and make WTO dispute settlement bodies accountable to WTO members.

Habitat selection and population regulation in temporally fluctuating environments

Understanding and predicting the distribution of organisms in heterogeneous environments lies at the heart of ecology, and the theory of density-dependent habitat selection (DDHS) provides ecologists with an inferential framework linking evolution and population dynamics. Current theory does not allow for temporal variation in habitat quality, a serious limitation when confronted with real ecological systems. We develop both a stochastic equivalent of the ideal free distribution to study how spatial patterns of habitat use depend on the magnitude and spatial correlation of environmental stochasticity and also a stochastic habitat selection rule. The emerging patterns are confronted with deterministic predictions based on isodar analysis, an established empirical approach to the analysis of habitat selection patterns. Our simulations highlight some consistent patterns of habitat use, indicating that it is possible to make inferences about the habitat selection process based on observed patterns of habitat use. However, isodar analysis gives results that are contingent on the magnitude and spatial correlation of environmental stochasticity. Hence, DDHS is better revealed by a measure of habitat selectivity than by empirical isodars. The detection of DDHS is but a small component of isodar theory, which remains an important conceptual framework for linking evolutionary strategies in behavior and population dynamics.

The comparative impact of privatisation and regulation on productivity growth in the English and Welsh water and sewerage industry, 1985-99

After the 10 regional water authorities of England and Wales were privatized in November 1989, the successor WASCs (water and sewerage companies) faced a new regulatory regime that was designed to promote productivity growth while simultaneously improving drinking water and environmental quality. As legally mandated quality improvements necessitated a costly capital investment programme, the industry's economic regulator – the Office of Water Services – implemented a RPI + K pricing system, designed to compensate the WASCs for their capital investment programme while also encouraging faster rates of productivity growth. This paper considers the relative effects of privatization and regulation on productivity growth in the industry using both non-parametric and parametric methods to provide a crosscheck on the robustness of the results. While there is evidence that labour productivity improved after privatization, there is no evidence that privatization led to a growth in TFP (total factor productivity). However, there is some evidence of a small increase in the rate of TFP growth in the aftermath of a substantial tightening of the regulatory regime that took place in 1995. These results, therefore, are consistent with evidence from other research that privatization, in the absence of effective competition and/or regulation, is not necessarily associated with improved economic performance.

Food colours:a study of the effects of regulation

In the 1960s the benefits of government regulation of technology were believed to outweigh any costs. But recent studies have claimed that regulation has negative effects on innovation, health and consumer choice. This case study on food colours examines such claims. EFFECTS ON HEALTH were measured by allocating a hazard rating to each colour. The negative list of 1925 removed three harmful colours which were rapidly replaced, so the benefits were short-lived. Had a proposed ban been adopted in the 1860s it would have prevented many years exposure to hazardous mineral colours. The positive list of 1957 reduced the proportion of harmful coal tar dyes from 54% of the total to 20%. Regulations brought a greater reduction in hazard levels than voluntary trade action. Delays in the introduction of a positive list created a significant hazard burden. EFFECTS ON INNOVATION were assessed from patents and discovery dates. Until the 1950s food colours were adopted from textile colours. The major period of innovation for coal tar colours was between 1856 and 1910, finishing well before regulations were made in 1957, so regulations cannot be blamed for the decline. Regulations appear to have spurred the development of at least one new coal tar dye, and many new plant colours, creating a new sector of the dye industry. EFFECTS ON CONSUMER CHOICE were assessed by case studies. Coloured milk, for example, was banned despite its popularity. Regulations have restricted choice, but have removed from the market foods that were nutritionally impoverished and poor value for money. Compositional regulations provided health protection because they reduced total exposure to colours from certain staple foods. Restricting colours to a smaller range of foods would be an effective way of coping with problems of quality and imperfect toxicological knowledge today.

The impact of privatisation and regulation on the water and sewerage industry in England and Wales:a translog cost function approach

After the ten Regional Water Authorities (RWAs) of England and Wales were privatized in November 1989, the successor Water and Sewerage Companies (WASCs) faced a new regulatory regime that was designed to promote economic efficiency while simultaneously improving drinking water and environmental quality. As legally mandated quality improvements necessitated a costly capital investment programme, the industry's economic regulator, the Office of Water Services (Ofwat), implemented a retail price index (RPI)+K pricing system, which was designed to compensate the WASCs for their capital investment programme while also encouraging gains in economic efficiency. In order to analyse jointly the impact of privatization, as well as the impact of increasingly stringent economic and environmental regulation on the WASCs' economic performance, this paper estimates a translog multiple output cost function model for the period 1985–1999. Given the significant costs associated with water quality improvements, the model is augmented to include the impact of drinking water quality and environmental quality on total costs. The model is then employed to determine the extent of scale and scope economies in the water and sewerage industry, as well as the impact of privatization and economic regulation on economic efficiency.

Giving whistleblowers greater protection:improving quality of care

This year, an independent review of whisleblowing in the NHS made recommendations as to how whistleblowers could be given greater protection. The review, chaired by Sir Robert Francis, intended to improve the quality of patient care and safety in the health service. But with many practitioners remaining unregulated, there are unanswered questions as to how reports of mistakes can be properly investigated and the necessary action taken against incompetent or negligent practitioners. Amanda Casey, Chair of the Registration Council for Clinical Physiologists, makes the case for regulation of professionals whose work poses potential risks to patients and can place healthcare managers in an invidious position.
