In line with global changes, the UK regulatory regime for audit and corporate governance has changed significantly since the Enron scandal, with an increased role for audit committees and independent inspection of audit firms. UK listed company chief financial officers (CFOs), audit committee chairs (ACCs) and audit partners (APs) were surveyed in 2007 to obtain views on the impact of 36 economic and regulatory factors on audit quality. 498 usable responses were received, representing a response rate of 36%. All groups rated various audit committee interactions with auditors among the factors most enhancing audit quality. Exploratory factor analysis reduces the 36 factors to nine uncorrelated dimensions. In order of extraction, these are: economic risk; audit committee activities; risk of regulatory action; audit firm ethics; economic independence of auditor; audit partner rotation; risk of client loss; audit firm size; and, lastly, International Standards on Auditing (ISAs) and audit inspection. In addition to the activities of the audit committee, risk factors for the auditor (both economic and certain regulatory risks) are believed to most enhance audit quality. However, ISAs and the audit inspection regime, aspects of the ‘standards-surveillance compliance’ regulatory system, are viewed as less effective. Respondents commented that aspects of the changed regime are largely process and compliance driven, with high costs for limited benefits, supporting psychological bias regulation theory that claims there is overconfidence that a useful regulatory intervention exists.

It has long been said that market itself is the ideal regulator of all evils that may come up among traders. Free and fair competition among manufacturers in the market will adequately ensure a fair dealing to the consumers. However, these are pious hopes. that markets anywhere in the world could not accomplish so far. Consumers are being sought to be lured by advertisements issued by manufacturers and sellers that are found often false and misleading. Untrue statements and claims about quality and performance of the products virtually deceive them. The plight of the consumers remains as an unheard cry in the wildemess. In this sorry state of affairs, it is quite natural that the consumers look to the governments for a helping hand. It is seen that the governmental endeavours to ensure quality in goods are diversified. Different tools are formulated and put to use, depending upon the requirements necessitated by the facts and circumstances. This thesis is an enquiry into these measures

This paper develops a structural model which allows estimating the impact of regulatory decisions looking for the setting of download-speed standards on market structure and performance. We characterize a setting under which quality standards improve both service quality and availability. As to quality, we evaluate the impact of quality standards on the performance of local demand from a detailed database of broadband internet subscribers, discriminated by the main attributes of an internet subscription contract as location, supplier, monthly-fee, download- and upload-speed features. From these results, we are able to identify the effect of quality regulation on the behavior of internet providers in a differentiated product market approach. As a consequence, we are able to assert that the response of internet service providers to quality regulation is a more intense product differentiation that contributes to demand expansion and therefore to improve broadband penetration indicators.

Nos tempos atuais as empresas que atuam no ramo dos sistemas elétricos de energias enfrentam desafios cada vez mais exigentes, dado o enquadramento normativo a que estão sujeitas por parte da entidade reguladora dos serviços energéticos. No caso do Arquipélago dos Açores, o normativo relativo ao regulamento da qualidade de serviço entrou em vigor em 2006, trazendo à EDA,S.A. (Eletricidade dos Açores), entidade responsável pelo transporte e distribuição de energia na região, novas exigências para adequados níveis de eficiência e de garantias aos clientes, no que respeita à qualidade de serviço que lhes é prestado. No âmbito deste trabalho, é efetuado o estudo do trânsito de potência sobre a rede distribuição 15 kV da ilha Graciosa. Para tal, é realizada a modelização da rede no software de rede elétricas porwerworld 8.0. e são idealizados um conjunto de cenários de exploração da rede, que visam simular situações reais que ocorrem na exploração diária da rede de distribuição da ilha. Nas simulações a efetuar consideram-se dois cenários com perfil de carga distintos, um referente à ponta máxima, e outro referente ao vazio mínimo, verificados no ano de 2014. Quanto ao modo de exploração da rede nos cenários a simular, é contemplado o modo de exploração normalmente operado pela empresa gestora, bem como diversas reconfigurações sobre o modo de exploração normalmente operado, realizadas através da abertura e fecho dos aparelhos de corte constituintes da rede. Em todos os cenários simulados, é realizado um estudo relativamente à potência de perdas do sistema, ao perfil da tensão nos diversos postos de transformação, e ao congestionamento de energia verificado nas linhas de distribuição da rede.

The major task of policy makers and practitioners when confronted with a resource management problem is to decide on the potential solution(s) to adopt from a range of available options. However, this process is unlikely to be successful and cost effective without access to an independently verified and comprehensive available list of options. There is currently burgeoning interest in ecosystem services and quantitative assessments of their importance and value. Recognition of the value of ecosystem services to human well-being represents an increasingly important argument for protecting and restoring the natural environment, alongside the moral and ethical justifications for conservation. As well as understanding the benefits of ecosystem services, it is also important to synthesize the practical interventions that are capable of maintaining and/or enhancing these services. Apart from pest regulation, pollination, and global climate regulation, this type of exercise has attracted relatively little attention. Through a systematic consultation exercise, we identify a candidate list of 296 possible interventions across the main regulating services of air quality regulation, climate regulation, water flow regulation, erosion regulation, water purification and waste treatment, disease regulation, pest regulation, pollination and natural hazard regulation. The range of interventions differs greatly between habitats and services depending upon the ease of manipulation and the level of research intensity. Some interventions have the potential to deliver benefits across a range of regulating services, especially those that reduce soil loss and maintain forest cover. Synthesis and applications: Solution scanning is important for questioning existing knowledge and identifying the range of options available to researchers and practitioners, as well as serving as the necessary basis for assessing cost effectiveness and guiding implementation strategies. We recommend that it become a routine part of decision making in all environmental policy areas.

Sähkömarkkinauudistukset ovat tuoneet kilpailun sähkön tuotantoon ja myyntiin, mutta samalla vahvistaneet tarvetta valvoa sähkönsiirtoa ja -jakelua, jotka ovat ns. luonnollisia monopolitoimintoja. Monopoleja valvotaan, jotta ne eivät väärinkäytä määräävää markkina-asemaansa. Tässä diplomityössä tarkastellaan sähkönjakeluverkkoliiketoiminnan sääntelyyn yleisesti käytettyjä valvontamalleja sekä niiden soveltamisessa huomioon otettavia seikkoja. Tarkasteltuja valvontamalleja on neljä, joista yleisimpiä ovat hintakattosääntely ja liikevaihdon sääntely. Tuoton sääntely on monesti ollut ensimmäinen keino säännellä alaa. Mittatikkusääntelyllä pyritään selvittämään tarkasteltavien yhtiöiden tehokkuutta. Sitä käytetään yleensä muiden mallien lisänä kannustamaan toiminnan tehostamiseen. Yhä useammin valvotaan myös sähköntoimituksen laatua. Jokainen maa valitsee omaan erityistilanteeseensa parhaiten sopivan valvontamallin. Valvontamallit kehittyvät jatkuvasti, jotta asiakkaiden etujen turvaamiseksi on olemassa toimivat regulatiiviset työkalut ja toisaalta sähkönjakeluyhtiöiden toimintaolosuhteet ovat vakaat ja realistiset. Kansallisen regulaattorin on luotava valvontamallin avulla oikeanlaiset kannustimet yhtiöiden toiminnalle, jotta niiden tekemät investointi- ja toimintapäätökset ovat järkeviä ja takaavat sähkönjakelun jatkuvuuden.

Deregulation of the electricity sector liberated the electricity sale and production for competitive forces while in the network business, electricity transmission and distribution, natural monopoly positions were recognised. Deregulation was accompanied by efficiencyoriented thinking on the whole electricity supply industry. For electricity distribution this meant a transition from a public service towards profit-driven business guided by economic regulation. Regulation is the primary means to enforce societal and other goals in the regulated monopoly sector. The design of economic regulation is concerned with two main attributes; end-customer price and quality of electricity distribution services. Regulation limits the costs of the regulated company but also defines the desired quality of monopoly services. The characteristics of the regulatory framework and the incentives it provides are therefore decisive for the electricity distribution sector. Regulation is not a static factor; changes in the regulatory practices cause discontinuity points, which in turn generate risks. A variety of social and environmental concerns together with technological advancements have emphasised the relevance of quality regulation, which is expected to lead to the large-scale replacement of overhead lines with underground cables. The electricity network construction activity is therefore currently witnessing revolutionary changes in its competitive landscape. In a business characterised by high statutory involvement and a high level of sunk costs, recognising and understanding the regulatory risks becomes a key success factor. As a response, electricity distribution companies have turned into outsourcing to attain efficiency and quality goals. This doctoral thesis addresses the impacts of regulatory risks on electricity network construction, which is a commonly outsourced activity in the electricity distribution network sector. The chosen research approach is characterised as an action analytical research on account of the fact that regulatory risks are greatly dependent on the individual nature of the regulatory regime applied in the electricity distribution sector. The main contribution of this doctoral thesis is to develop a concept for recognising and managing the business risks stemming from economic regulation. The degree of outsourcing in the sector is expected to increase in years to come. The results of the research provide new knowledge to manage the regulatory risks when outsourcing services.

Improved understanding and prediction of the fundamental environmental controls on ecosystem service supply across the landscape will help to inform decisions made by policy makers and land-water managers. To evaluate this issue for a local catchment case study, we explored metrics and spatial patterns of service supply for water quality regulation, agriculture production, carbon storage, and biodiversity for the Macronutrient Conwy catchment. Methods included using ecosystem models such as LUCI and JULES, integration of national scale field survey datasets, earth observation products and plant trait databases, to produce finely resolved maps of species richness and primary production. Analyses were done with both 1x1 km gridded and subcatchment data. A common single gradient characterised catchment scale ecosystem services supply with agricultural production and carbon storage at opposing ends of the gradient as reported for a national-scale assessment. Species diversity was positively related to production due to the below national average productivity levels in the Conwy combined with the unimodal relationship between biodiversity and productivity at the national scale. In contrast to the national scale assessment, a strong reduction in water quality as production increased was observed in these low productive systems. Various soil variables were tested for their predictive power of ecosystem service supply. Soil carbon, nitrogen, their ratio and soil pH all had double the power of rainfall and altitude, each explaining around 45% of variation but soil pH is proposed as a potential metric for ecosystem service supply potential as it is a simple and practical metric which can be carried out in the field with crowd-sourcing technologies now available. The study emphasises the importance of considering multiple ecosystem services together due to the complexity of covariation at local and national scales, and the benefits of exploiting a wide range of metrics for each service to enhance data robustness.

Este estudo analisa os resultados da mudança na estrutura de regulação do serviço público de energia elétrica, implementada, no âmbito da Reforma do Estado, no final dos anos 1990. Foi comparada a qualidade do serviço de distribuição no fornecimento de energia elétrica de duas empresas que atuam no Norte do Brasil, uma pública, outra privada. A última, ao ser penalizada pela agência reguladora, recorreu, sistematicamente, à judicialização dos processos punitivos. Essa estratégia não foi observada na atuação da empresa pública. Tal possibilidade institucional decorre de as agências serem dependentes do Judiciário que opera sob lógica estruturalmente diferente da lógica gerencial. Concluiu-se que a judicialização enseja comportamentos baseados na procrastinação no âmbito do arcabouço regulatório dos serviços públicos, bloqueando a estratégia pública de regulação.

This paper applies a policy analysis approach to the question of how to effectively regulate micropollution in a sustainable manner. Micropollution is a complex policy problem characterized by a huge number and diversity of chemical substances, as well as various entry paths into the aquatic environment. It challenges traditional water quality management by calling for new technologies in wastewater treatment and behavioral changes in industry, agriculture and civil society. In light of such challenges, the question arises as to how to regulate such a complex phenomenon to ensure water quality is maintained in the future? What can we learn from past experiences in water quality regulation? To answer these questions, policy analysis strongly focuses on the design and choice of policy instruments and the mix of such measures. In this paper, we review instruments commonly used in past water quality regulation. We evaluate their ability to respond to the characteristics of a more recent water quality problem, i.e., micropollution, in a sustainable way. This way, we develop a new framework that integrates both the problem dimension (i.e., causes and effects of a problem) as well as the sustainability dimension (e.g., long-term, cross-sectoral and multi-level) to assess which policy instruments are best suited to regulate micropollution. We thus conclude that sustainability criteria help to identify an appropriate instrument mix of end-of-pipe and source-directed measures to reduce aquatic micropollution.

Most major cities in the eastern United States have air quality deemed unhealthy by the EPA under a set of regulations known as the National Ambient Air Quality Standards (NAAQS). The worst air quality in Maryland is measured in Edgewood, MD, a small community located along the Chesapeake Bay and generally downwind of Baltimore during hot, summertime days. Direct measurements and numerical simulations were used to investigate how meteorology and chemistry conspire to create adverse levels of photochemical smog especially at this coastal location. Ozone (O3) and oxidized reactive nitrogen (NOy), a family of ozone precursors, were measured over the Chesapeake Bay during a ten day experiment in July 2011 to better understand the formation of ozone over the Bay and its impact on coastal communities such as Edgewood. Ozone over the Bay during the afternoon was 10% to 20% higher than the closest upwind ground sites. A combination of complex boundary layer dynamics, deposition rates, and unaccounted marine emissions play an integral role in the regional maximum of ozone over the Bay. The CAMx regional air quality model was assessed and enhanced through comparison with data from NASA’s 2011 DISCOVER-AQ field campaign. Comparisons show a model overestimate of NOy by +86.2% and a model underestimate of formaldehyde (HCHO) by –28.3%. I present a revised model framework that better captures these observations and the response of ozone to reductions of precursor emissions. Incremental controls on electricity generating stations will produce greater benefits for surface ozone while additional controls on mobile sources may yield less benefit because cars emit less pollution than expected. Model results also indicate that as ozone concentrations improve with decreasing anthropogenic emissions, the photochemical lifetime of tropospheric ozone increases. The lifetime of ozone lengthens because the two primary gas-phase sinks for odd oxygen (Ox ≈ NO2 + O3) – attack by hydroperoxyl radicals (HO2) on ozone and formation of nitrate – weaken with decreasing pollutant emissions. This unintended consequence of air quality regulation causes pollutants to persist longer in the atmosphere, and indicates that pollutant transport between states and countries will likely play a greater role in the future.
