Electricity sector reform in developing countries: an econometric assessment of the effects of privatization,competition and regulation

Electricity sectors in both developed and developing countries have been subject to restructuring to introduce private capital and increase competition. Although the effects of such reforms in a number of the developed economies are now well documented, the experience of developing countries is much less well researched. This paper provides an econometric assessment of the effects of privatization, competition and regulation on the performance of the electricity generation industry using panel data for 36 developing and transitional countries, over the period 1985–2003. The study identifies the impact of these reforms on generating capacity, electricity generated, labor productivity in the generating sector and capacity utilization. The main conclusions are that on their own privatization and regulation (PR) do not lead to obvious gains in economic performance, though there are some positive interaction effects. By contrast, introducing competition does seem to be effective in stimulating performance improvements.      

Planned adaptation in risk regulation: An initial survey of US environmental, health, and safety regulation

In principle, we want regulatory programs to be based on current realities, as reflected for example in the best knowledge of relevant experts. That would imply that old rules now on the books should be consistent with today's knowledge base, not just what was known when a rule or standard was originally set. This paper reports on a survey of US programs, examining how often existing rules are actually updated in light of better knowledge, and identifies five programs that attempt to make policy routinely adaptive. These programs exhibit what we term Planned Adaptation: they both revise rules when relevant new knowledge appears, and take steps to produce such improved knowledge. While Planned Adaptation is rare, it is used in several nationally prominent programs, including air pollution, airplane safety, and drug safety. Planned Adaptation is a policy tool that deserves more attention.     

Drivers of technological capabilities in developing countries: An econometric analysis of Argentina,Brazil and Chile

This paper contributes to the literature that analyses the determinants and measurement of Technological Capabilities (TCs) with empirical evidence on Argentina, Brazil and Chile. Based on the World Bank's Investment Climate database, the study covers firms from the manufacturing sector. We first construct a Capability Score to provide a preliminary measure of Technological Capabilities at the firm level. We then test it econometrically to explore the determinants of TCs and exports and evaluate their reciprocal relationship through a Two Stage Probit. Our results show that exports and TCs significantly and positively influence each other in some of these countries.     

The 2001-3 electricity distribution price control review in the Netherlands: regulatory process and consumer welfare

The outcome of the first electricity distribution price control review in The Netherlands did not deliver the savings initially suggested by the regulator (DTe). During the course of the first 3-year regulatory period, DTe revised the X-Factors four times. The impact on tariffs has been substantial. DTe initially announced in 2000 that savings would be equivalent to 25% of electric distribution revenues ( 2bn). However, final X-Factors in May 2003 resulted in savings of 10% of revenues. The total cost to consumers—when compared to the most probable outcome—has been 140 mln (7% of total revenues).      

Stipulated settlements,the consumer advocate and utility regulation in Florida

US utility regulation is evolving. Negotiated or stipulated settlements have begun to replace or supplement litigation, but relatively little seems to be known about this practice. This paper presents evidence from Florida. During 1976–2002, 30% of earnings reviews were settled by stipulations involving the Office of Public Counsel but only 7% of company requests. The mean value of a rate reduction was eight times larger with a stipulation than without; the median value was more than 50 times larger. Over three quarters of the rate reductions associated with earnings reviews derived from these stipulations; excluding one exceptional case the proportion was 94%. Sanford Berg and Paul Sotkevitz kindly briefed me on stipulations and introduced me to the Florida Public Service Commission. I am particularly indebted to Dale Mailhot of the Commission for explaining the regulatory processes, allowing me access to the database, and patiently clarifying the details and background. I am grateful to Bonnie Davis, Jack Shreve and Scheff Wright for enlightening discussions in Tallahassie; to Dan Fessler and Steven Weissman for discussion of this topic in California; to Ashley Brown, Robert Burns, Joseph Doucet, Guy Holburn, Mark Jamison, Paul Joskow, Paul Sotkevitz, Pablo Spiller and James Wilson for related discussion and comments; and to two referees for helpful suggestions. I thank the Judge Business School and the TSEC grant to the Electricity Policy Research Group at Cambridge University for facilitating this research. None of the above is responsible for views expressed herein. Some outline results of the early research were given in Littlechild (2003).

The relationship between risk attitudes and heuristics in search tasks: A laboratory experiment

Experimental studies of search behavior suggest that individuals stop searching earlier than the optimal, risk-neutral stopping rule predicts. Two different classes of decision rules could generate this behavior: rules that are optimal conditional on utility functions departing from risk neutrality, or heuristics derived from limited cognitive processing capacities and satisficing. To discriminate between these possibilities, we conducted an experiment that consists of a search task as well as a lottery task designed to elicit utility functions. We find that search heuristics are not related to measures of risk aversion, but to measures of loss aversion.     

信用风险缓释工具市场的监管变革与中国实践

信用风险缓释工具在包括资产证券化在内的金融市场上扮演着重要角色,但交易的集中化、投机化和去监管化却蕴积出市场风险,并在次贷危机中集中爆发。汲取危机教训,美国Dodd-Frank法案和国际掉期协会ISDA制定的大/小爆炸协议代表着市场监管的初步建立。有鉴于此,在我国现行的CRM场内交易机制下,要进一步对交易主体资格、交易信息披露、履约争议解决、市场稳定性影响等事项构建严格的持续监管机制。     

Trends affecting the next generation of U.S. agricultural biotechnology: Politics, policy, and plant-made pharmaceuticals

This paper analyzes the structure and history of regulatory policies in the United States, focusing on recent regulatory changes due to the promise and threat posed by plant-made pharmaceuticals (PMPs). PMPs are the latest advance in the genetic engineering of plants and promise to produce medicines inexpensively and abundantly by using a range of different plants as factories to express active medicinal ingredients; however, PMPs may pose a risk to the public's health if they enter the food supply. How the benefits and risks of PMPs are addressed by the respective government's regulation and how this will affect what, if any, products make it to the marketplace and their ultimate success are of great concern to many different parties, ranging from consumers and farmers to health and food production industries. As a result, this paper addresses the history of agricultural biotechnology regulatory policy since 1972, arguing that three distinct periods may be identified: (1) from 1972 to 1986 when the new biotechnology was focused on scientific self-regulation in the laboratory; (2) from 1987 to 2002, as the technology was being developed and widespread release of certain technologies became more common and was not perceived as an environmental threat, regulations became increasingly laxer; and finally, (3) we argue that we are entering a third phase with a series of controversies over regulatory infractions involving genetically engineered (GE) plants and the potential threats posed by PMPs.     

Women in Business in Late Nineteenth-Century Chile: Class,Marital Status,and Economic Autonomy

This article analyzes Chilean women’s entrepreneurial activity in the 1877–1908 period examining two official data sources representing different socioeconomic business niches – the national trademark registry, which represents the elite among business people, and the Santiago business license registry, which includes the non-elite. The analysis reveals an economy with women engaging increasingly in business in an expanding range of sectors. By the 1890s, women managed nearly a quarter of Santiago’s firms and 5 percent of elite firms nationally. Widows appeared overrepresented among elite businesses and underrepresented among those of the non-elite. These results suggest that institutions constraining entrepreneurship among married women were more strongly enforced among the elite than among other social classes. The evidence thus suggests that during late nineteenth century there was an increase in the economic autonomy exercised by unmarried women and widows of all socioeconomic strata, but also by married women among the non-elite.     

Treatment experience,burden, and unmet needs (TRIBUNE) in Multiple Sclerosis study: the costs and utilities of MS patients in The Netherlands

Abstract

Background:

Multiple sclerosis (MS) is an important, highly disabling neurological disease, common among young adults in The Netherlands. Nevertheless, only a few studies to date have measured the burden imposed by MS on society in The Netherlands.

Objectives:

To estimate the cost and quality-of-life associated with MS in The Netherlands, while focusing on the burden of relapses and increasing disease severity.

Methods:

MS patients in The Netherlands (n?=?263) completed a web-based questionnaire which captured information on demographics, disease characteristics and severity (Expanded Disability Status Scale [EDSS]), co-morbidities, relapses, resource consumption, utilities, fatigue and activities of daily living (ADL).

Results:

Most patients included in the study were receiving treatment for MS (76% of the sample). The mean cost per patient per year increased with worsening disability and was estimated at €30,938, €51,056, and €100,469 for patients with mild (EDSS 0–3), moderate (EDSS 4–6.5), and severe (EDSS 7–9) disability, respectively. The excess cost of relapses was estimated at €8195 among relapsing-remitting patients with EDSS score ≤5. The quality-of-life of patients decreased with disease progression and existence of relapses.

Conclusions:

The cost of MS in The Netherlands was higher compared to the results of previous studies. The TRIBUNE study provides an important update on the economic burden of MS in The Netherlands in an era of more widespread use of disease-modifying therapies. It explores the cost of MS linked to relapses and disease severity and examines the impact of MS on additional health outcomes beyond utilities such as ADL and fatigue.

Conclusions:

Deliberation,learning, and institutional change: the evolution of institutions in judicial settings

Institutional change entails institutional design, assessment, and modification, which necessarily take place within the constraints and opportunities afforded by existing institutional arrangements. Viktor Vanberg has made major contributions to our understanding of how institutions evolve. We wish to contribute to this symposium in honor of Vanberg by analyzing how institutions for the management of water institutions in Southern California evolved primarily through the use of the courts as settings for deliberation, learning and institutional change.

Rent, risk, and replication: Preference adaptation in winner-take-all markets

We study the evolution of an economy where agents who are heterogeneous with respect to risk attitudes can either earn a certain income or enter a risky rent-seeking contest. We assume that agents behave rationally given their preferences, but that the population distribution of preferences evolves over time in response to material payoffs. We show that, in particular, initial distributions with full support converge to stationary states where all types are still present. Although rents are perfectly dissipated in material terms at a steady state, efficiency is greater than if everybody had been risk neutral, since risk lovers specialize in rent seeking.     

Inbound open innovation in SMEs: indicators,non-financial outcomes and entry-timing

This study contributes to the literature on inbound open innovation in three ways. Firstly, it verifies the suitability of three groups of innovation activities (external information sources, cooperation and acquisition of machinery, knowledge or R&D) as indicators of open innovation, by modelling their relationship with the openness of the development of new products. Secondly, it relates these activities to three non-financial product-oriented outcomes of small and medium enterprises (SMEs): quality, product range and market share. When significant, the signs of the relationships are always positive. Thirdly, it is the first to link two streams of the literature on innovation within SMEs: open innovation and entry-timing. We distinguish between pioneers (the first to introduce innovations onto the market) and followers and find that most open innovation activities relate to the pioneering behaviour. This should be taken into consideration when designing public policies supporting innovation. Data include Spanish innovative SMEs from the Community Innovation Survey.     

经济发展中的地方官员行为研究——基于政治晋升、财政分权与腐败的视角

本文同时考虑财政分权、政治晋升和腐败三个因素对地方官员行为的影响,进而构建了理论模型。从中得到的主要结论是,在基本模型中,地方官员对政治晋升的偏好程度越高,则其努力程度越高、腐败程度越低。而财政分权程度越高,官员的努力也越高,但对腐败水平影响却是不确定的。在进一步假设腐败会被惩罚的拓展模型中,基本模型的大部分结论都没有发生太大变化,只是分权程度的对努力的影响也变得不确定了。除此之外,我们进一步研究了,对官员腐败惩罚的力度和对官员腐败的惩罚准确程度的影响,相关命题表明,如果对官员腐败惩罚的越严厉,并且对官员腐败的惩罚越准确,官员努力水平和官员腐败程度都会变低。通过对研究结论的分析,我们还对以往文献的结果进行了重新解释。     

Skilled and unskilled wage dynamics in Italy in the 1990s: changes in individual characteristics,institutions, trade and technology

In this paper, we use individual micro data on workers combined with industry and regional data to study the wage dynamics of skilled and unskilled workers in Italy in the 1991–1998 period. In contrast to previous empirical studies, our data make it possible to analyse, within a single framework, the role of many of the factors indicated in the literature as possible determinants of skilled and unskilled wage dynamics: changes in the individual characteristics of workers, changes in labour market institutions, increasing international integration, and skill‐biased technological progress. Our results show that international integration, both in terms of trade in goods and in terms of international labour mobility, plays a role in determining the wage dynamics of skilled (white‐collar) and unskilled (blue‐collar) workers. Moreover, in line with labour economics research, our findings show that the individual characteristics of workers and the institutional variables are more relevant in explaining skilled and unskilled wage dynamics than wage differentials.     

Water scarcity, social power and the production of an elite suburb: The political ecology of water in Matadepera, Catalonia

This article investigates the history of land and water transformations in Matadepera, a wealthy suburb of metropolitan Barcelona. Analysis is informed by theories of political ecology and methods of environmental history; although very relevant, these have received relatively little attention within ecological economics. Empirical material includes communications from the City Archives of Matadepera (1919-1979), 17 interviews with locals born between 1913 and 1958, and an exhaustive review of grey historical literature. Existing water histories of Barcelona and its outskirts portray a battle against natural water scarcity, hard won by heroic engineers and politicians acting for the good of the community. Our research in Matadepera tells a very different story. We reveal the production of a highly uneven landscape and waterscape through fierce political and power struggles. The evolution of Matadepera from a small rural village to an elite suburb was anything but spontaneous or peaceful. It was a socio-environmental project well intended by landowning elites and heavily fought by others. The struggle for the control of water went hand in hand with the land and political struggles that culminated - and were violently resolved - in the Spanish Civil War. The displacement of the economic and environmental costs of water use from few to many continues to this day and is constitutive of Matadepera's uneven and unsustainable landscape. By unravelling the relations of power that are inscribed in the urbanization of nature (Swyngedouw, 2004), we question the perceived wisdoms of contemporary water policy debates, particularly the notion of a natural scarcity that merits a technical or economic response. We argue that the water question is fundamentally a political question of environmental justice; it is about negotiating alternative visions of the future and deciding whose visions will be produced.     

Management of non-timber forestry products extraction: Local institutions, ecological knowledge and market structure in South-Eastern Zimbabwe

Common-pool resources (CPRs), such as forests, water resources and rangelands, provide a wide variety of economic benefits to forest-fringe dwellers in semi-arid areas of southern Africa. However, the public nature and competition involved in the use of these goods, and weak enforcement of institutional arrangements governing their use may lead to resource degradation. Using survey data from four communities in south-eastern Zimbabwe for 2008 and 2009, this paper examines the extent to which forest degradation is driven by existing common property management regimes resource and user characteristics, ecological knowledge and marketing structure. A Principal Component Analysis indicates that the existence of agreed-upon rules governing usage (including costs of usage), enforcement of these rules, sanctions for rule violations that are proportional to the severity of rule violation, social homogeneity, and strong beliefs in ancestral spirits were the most important attributes determining effectiveness of local institutions in the management of CPRs. Empirical results from a regression analysis showed that resource scarcity, market integration, and infrastructural development lead to greater resource degradation, while livestock income, high ecological knowledge, older households, and effective local institutional management of the commons reduce resource degradation. The results suggest that there is need for adaptive local management systems that enhance ecological knowledge of users and regulates market structure to favour long-term livelihood securities of these forest-fringe communities.     

Puzzles in the economic institutions of capitalism: production coordination, contracting and work organisation in the Irish linen trade, 1750-1850

Pre-Famine Ireland is a byword for market failure and path dependence.Production of flax yarn and linen cloth was highly regulatedand coordinated by the market rather than by firms. Contemporarypolitical economists suggested that these institutional featuresprovided evidence of organisational inefficiency. The historicalevidence suggests that they were a rational response to transactionand production costs. The Irish case provides a test of thehypotheses that firms emerge to reduce the cost of market transactions.It suggests that institutions other than the firm can modifytransaction costs, coordination of production can affect bothtransaction and production costs, and that agents choose betweenmarket and firm coordination given technology and factor prices.Finally, centralisation of production was driven by technology.     

On the importance of institutions and forms of organisation in Piero Sraffa's economics: the case of business cycles,money, and economic policy

Abstract

This paper is based on an investigation of the Sraffa Archives and tries to characterise Piero Sraffa's approach to business cycles and economic policy. It includes two parts. The first part of the paper shows the importance of economic institutions and social conventions in Sraffa's contribution to economics and their relation with social conflicts. The second part of the paper shows how this importance permits to understand better business cycles and economic policy but also indirectly contributes to a re-interpretation of Sraffa's contribution to economics.
