institutional determinants of power sector reform in pakistan the electricity supply sector in pakistan has performed poorly in recent years reforms were introduced in the mid 1990s to improve the sector but progressed slowly with no significant impacts on pre reform performance this study uses new institutional economics as a theoretical basis to elucidate reasons for the failure of power sector reforms in pakistan to make improvements interviews with 23 experts using q methodology generated 215 statements that were used as a q concourse of these 51 statements were selected for the q sample and ranked by 34 respondents depending on their importance analysis revealed four important discourses on the determinants of power sector reform failure in pakistan these included weak governance structure country and sectoral endowments inefficient regulator and unspecified political institutions or unfriendly political contexts the study recommends establishment of institutions that support a market based power supply sector and improvements to the contractual arrangements between stakeholders to reduce opportunistic behaviour

energy policy aid and the development of renewable energy resources in small island developing states abstract small island developing states sids have established ambitious renewable energy targets the promotion of renewable energy has been motivated by several factors a desire to lessen dependence on fossil fuels to attract development assistance in the energy sector and to strengthen the position of sids in climate change negotiations here we explore the interplay between the role of aid and energy policy in the development of renewable energy resources in sids we find that the importance of development assistance has implications for the sustainability of renewable energy development given that funding is not always accompanied by necessary energy policy reforms we also identify energy efficiency and access to modern energy services as having received insufficient attention in the establishment and structure of renewable energy targets in sids and argue that this is problematic due to the strong economic case for such investments

investment security of supply and sustainability in the aftermath of three decades of power sector reform the last three decades have witnessed many electricity industry reform processes in more than half of the countries in the world the reforms have aimed inter alia at encouraging private investments in electricity infrastructure enhancing security of electricity supply and making power industry operate in line with the requirements of the sustainable development using an original panel dataset from 55 developed and developing countries covering the period from 1975 to 2010 this study aims at finding out to what extent these objectives have been materialized so far econometric models are used to identify the effects of electricity market liberalization on these variables the research findings suggest that the progress toward the electricity market reform is associated with a decline in private investments in the electricity industries of developing countries higher levels of self sufficiency in electricity supply and lower co2 emissions from electricity generation

the philippine electricity sector reform and the urban question how metro manila s utility is tackling urban poverty in the early 2000s the philippine government reformed its electricity sector following neoliberal principles unbundling of the power industry privatisation of assets and commodification of electricity this paper shows that the reform was primarily driven by the need to secure electricity supply and cut down tariffs these national objectives ousted other issues and notably those that find their expression at the urban level among which the question of access to electricity in metro manila s urban poor communities the central state withdrew its attention from the issue of electrification and local actors had to react as they were confronted to social tensions and practices of pilferage as a consequence city governments and local administrations are getting involved in this issue which opens the way to participation of civil society this paper shows how the rolling back of the central state led to new partnerships and arrangements between the distribution utility local governments and community organisations this movement points to an urbanisation of energy issues which could bring positive results for end users provided that it is accompanied by a clearer regulatory framework

optimal taxation in models of endogenous growth we study the problem of optimal taxation in three infinite horizon representative agent endogenous growth models the first model is a convex model in which physical and human capital are perfectly symmetric our second model incorporates elastic labor supply through a lucas style technology analysis of these two models points out the danger of assuming that government expenditures are exogenous in our third model we include government expenditures as a productive input in capital formation showing that the limiting tax rate on capital is no longer zero in numerical simulations we find similar effects on growth and welfare in all three models

powering africa meeting the financing and reform challenges africa faces chronic power problems including insufficient generation capacity low connectivity poor reliability and high costs all of which constrain development power capacity additions in sub saharan africa excl sa since the 1990 s were minuscule historically investments in the power sector in africa have come mostly from governments or public utilities with foreign aid support in recent years these sources of funding have been flat the fastest new sources of funding are from independent power producers ipps and from china to understand the determinant of the new sources the paper analyses the effect of several key factor and find non expected results such as there is no obvious correlation between unbundling or the presence of an independent regulator and the level of private investment through ipps or that there is no correlation between chinese investment in generation and resource rich countries dispelling the myth that chinese firms are only interested in africa s resources the paper delivers several recommendations that indicate that more attention needs to be given to issues related to planning procurement and contracting as well as securing revenue flows jel classification o13 o25 l94

in search of the winner s curse earlier papers on the winner s curse have provided theoretical arguments that winning bidders in an auction will incur ex post losses even when all bidders use reasonable ex ante bidding strategies this paper demonstrates that these arguments are erroneous optimal ex ante bidders will never suffer from a winner s curse in an auction where only the winning bid is announced furthermore such bidders will on the average not suffer from a winner s curse in an auction where all bids are announced thus if a winner s curse is a behavioral reality then bidders are not generally using ex ante optimal strategies

independent power projects in sub saharan africa investment trends and policy lessons abstract sub saharan africa is in urgent need of more power private sector investment is key to achieving this along with chinese funded projects independent power projects ipp represent the fastest growing sources of power investment in sub saharan africa ipp investment flows show little concern for electricity market structures but are more likely to gravitate to countries with strong planning procurement and contracting capacity as well as good regulatory quality data from the continent also shows a variety of ownership and financing structures for ipps but generally development financing institutions dfis play an important part in mitigating risk and bringing in private financiers we also see renewable energy breaking through on the continent both in scale and price this breakthrough is in part being facilitated by competitive procurement or auctions which deliver lower prices and increased transparency when compared with renewable energy feed in tariffs or directly negotiated contracts these developments have important policy implications highlighting the need for dynamic least cost planning linked to the timely initiation of the competitive procurement of new generation capacity the building of effective regulatory capacity and appropriate risk mitigation mechanisms such efforts promise to promote sustainable economic and social development across the continent

redistributive taxation in a simple perfect foresight model abstract we investigate the redistributive potential of capital taxation in an intertemporal maximizing model of capital formation first even unanticipated redistributive capital taxation is severely limited in its effectiveness since it depresses wages second under any convergent redistributive tax policy which maximizes a paretian social objective the capital income tax will converge to zero independent of the factor supply elasticities these results are independent of workers holdings of capital

getting reforms done in inhospitable institutional environments untying a gordian knot in india s power distribution sector when grand institutional reforms based on idealized models are stalled by the poor institutional environments and difficult politics which often surround large infrastructure systems in developing countries partial reforms whose design and implementation take into account the different interests of the key stakeholders can provide valuable and immediate benefits while moving these systems from low towards higher level equilibria strategically negotiated experimentally partial and purposefully hybrid these reforms are based on careful stakeholder analysis and strategic coalition building that avoid rigid positions based on idealized models our findings are based on a study of power sector reforms in india where we performed a micro level and in depth analysis of a partial and innovative experiment which has allowed private sector participation in electricity distribution within a hostile institutional environment

power sector reform in developing countries mismatched agendas power sector reform is rapidly spreading across all corners of the developing world at an alarmingly rapid pace while the rationales for reform seem to have gained acceptance among the stakeholders the reform model and process are contested this paper examines the impacts of reform using the promised outcomes as a basis for analysis the ability of reform to meet the developmental challenges facing the reformers is explored it concludes that reform has had some achievements if conventional performance indicators are used but also questions the validity of some of these indicators reform has however not fulfilled many of its goals and the prevailing recipes are likely to leave developing countries socially and economically worse off than in the pre reform period progressive government intervention is needed to shift reform process towards a more responsible development path

business cycles and the relationship between concentration and price cost margins using a newly constructed panel data base we examine changes in price cost margins in 284 manufacturing industries between 1958 and 1981 a key finding is a dramatic narrowing of the spread between the margins of concentrated and unconcentrated industries over this period we provide evidence that this narrowing is a result of the greater sensitivity of price cost margins in more concentrated industries to demand fluctuations this finding is robust to the inclusion of other industry variables and to measures of import competition the results indicate that cross sectional estimates of the concentration margins relationship are likely to be both biased and misleading

the impact of power market reforms on electricity price cost margins and cross subsidy levels a cross country panel data analysis abstract one of the main expectations from power market reform has been a reduction in both price cost margins and cross subsidy levels between industrial and residential consumers this paper focuses on this issue by looking at the impact of the electricity industry reforms on residential and industrial electricity price cost margins and their effect on cross subsidy levels between consumer groups using panel data for 63 developed and developing countries covering the period 1982 2009 empirical models are developed and analyzed the research findings suggest that there is no uniform pattern for the impact of reform process as a whole on price cost margins and cross subsidy levels each individual reform step has different impact on price cost margins and cross subsidy levels for each consumer and country group our findings imply that reform steps have different impacts in different countries which supports the idea reform prescription for a specific country cannot easily and successfully be transferred to another one so transferring the formal and economic structure of a successful power market in a developed country to developing countries is not a sufficient condition for good economic performance of the electricity industries in developing countries furthermore the study suggests that power consumption income level and country specific features constitute other important determinants of electricity price cost margins and cross subsidy levels

capital income taxation with imperfect competition a key feature of modern dynamic economies is imperfect competition some imperfect competition is due to institutions such as patents and copyrights that allow firms to exercise market power over the sale of products they invent some imperfect competition is due to various forms of increasing returns to scale and product differentiation since market power is an essential feature of innovation and growth in the new economy as it was in the old economy we need to know how imperfect competition affects the conventional wisdom on tax policy i argue that it has particularly striking implications for the taxation of capital the current consensus among economists is

the importance of asymmetric tax policy and dangers of aggregation existing tax policies have many complex features that make distinctions across goods factors and financial structures that distort economic allocations their importance is ignored when tax policy is summarized by an effective tax rate in fact the losses due to asymmetries are often larger than the losses due to the level of taxation

fiscal policy inflation and the accumulation of risky capital the effect of government policies on the level of investment and inflation has become a major concern of policy makers in a number of industrial countries proposals to raise the level of business investment have included overall tax cuts tax incentives to spur investment and a reduction in the level of government spending this paper presents a theoretical apparatus to explore the relationships between fiscal policy government debt inflation and capital accumulation it develops a one sector growth model embodying a stochastic production function and government fiscal policy atomistic agents in the economy choose consumption levels and allocate their wealth between risky capital and risky government debt to maximize expected discounted utility over an infinite horizon fiscal policy by affecting asset yields affects the composition of portfolios the price of government bonds and the accumulation of capital the model is used to answer three general questions 1 does the level of government expenditure affect the rate of capital accumulation and inflation in steady state 2 does the mode of government finance when the choice is between an income tax and deficit finance affect these magnitudes 3 what is the effect of uncertainty in the productivity of capital on growth the analysis relates to several areas of literature 1 the analysis of the relationship between capital accumulation and debt 2 the theory of the demand for government debt 3 considerations of the effect of income taxation on risk bearing and 4 the analysis of capital accumulation under uncertainty 1 the effects on output and the capital stock of the government s expenditure decision and its decision to finance its expenditure by taxation or debt issue are explored in two major bodies of economic theory the literature on the burden of the debt as developed by modigliani 1961 diamond 1965 and phelps and shell 1969 for example implies that policies which increase the value of outstanding government debt will tend to lower the level of the capital stock by displacing capital with public debt in private wealth the theory of money and growth as represented by tobin 1965 and sidrauski 1967b also implies that government debt displaces capital but specifically recognizes the role of capital gains on government debt

optimal taxation and spending in general competitive growth models abstract we find that the optimal long run tax on capital income is zero even if the capital stock does not converge to a steady state nor to a steady state growth rate the optimal tax on human capital is also zero if human capital is not a final good but the long run wage tax is not generally zero we argue that consumption tax proposals such as the flat tax are not consumption taxes and are biased against human capital

review of proposals for practical power sector restructuring and reforms in a dynamic electricity supply industry abstract south africa s electricity supply industry esi remains a vertically integrated monopoly despite global trends towards restructuring the monopolistic nature of the esi could hinder the development of distributed power systems as penetration of renewable electricity increases the research aims to rationalise south africa s esi evolution propose practical power sector restructuring in the short to medium term and to determine their potential impact the research methodology included a single case study instrument with embedded sub units of analysis primary research data was gathered using semi structured interviews with industry experts in addition to which secondary data from government documents and archival records were used for triangulation research results conclude that south africa s esi grew due to techno economic industrialisation factors while apartheid era policies influenced the esi in only some specific respects the vertically integrated status quo was sustained in the post transformation period due to government s focus on social imperatives lack of regulatory policy certainty and conflicts in political ideology south africa did not experience the pre conditions that triggered global power sector reforms in the late 20 th century but these pre conditions are now becoming evident privatisation of eskom generation and introduction of wholesale and retail competition are not practical in the short to medium term proving the infeasibility of the standard model of reform locally the introduction of an independent system and market operator ismo using a single buyer model is seen as the most favourable and practical option with the ismo owning transmission infrastructure the research suggests that esi changes will increase system efficiencies economic performance and private sector involvement but will not reduce electricity tariffs the scenarios challenges and proposals identified in this research are also applicable to other countries in africa and other developing regions of the world that have similar social and political backgrounds ensuring sustainable supply of electricity

the welfare cost of factor taxation in a perfect foresight model this paper examines the marginal efficiency cost of various factor taxes in a dynamic general equilibrium model the au thor solves for the excess burden of anticipated and unanticipated t emporary and permanent tax policies using a range of estimates for taste and technology parameters he finds excess burdens larger than those indicated by previous studies that use static models these exc ess burdens are sensitive to parameter values and timing however th e rankings of alternative tax policies turn out to be insensitive to structural parameter values copyright 1987 by university of chicago press

reform despite politics the political economy of power sector reform in fiji 1996 2013 abstract attempts to reform the electricity sector in developing countries have achieved mixed results despite the implementation of similar reforms in many developed countries and concerted effort by donors to transfer reform models in many cases political obstacles have prevented full and effective implementation of donor promoted reforms this paper examines the political economy of power sector reform in fiji from 1996 to 2013 reform has been pursued with political motives in a context of clientelism policy inconsistency and reversal is explained by the political instability of ethnic based politics in fiji modest success has been achieved in recent years despite these challenges with fiji now considered a model of power sector reform for other small islands developing states sids in the pacific the experience demonstrates that reform is possible within difficult political environments but it is challenging takes time and is not guaranteed the way in which political motives have driven and shaped reform efforts also highlights the need for studies of power sector reform to direct greater attention toward political drivers behind reform

implications of liberalization policies on government support to r d lessons from electricity markets since the early 1980s electricity industry reforms have been initiated in more than half of the countries in the world among the primary targets of these reform schemes there has been an increase in efficiency of the sector and it is implicitly assumed that government support to energy technology r d will progress in line with the reform process as the former is required to sustain improved efficiency in the middle and long run the paper reviews the relation between reform process in electricity markets and government support to energy r d using panel data from 27 countries covering the period from 1974 to 2008 this study aims at finding out to what extent the expected correlation between reform process and government support to energy r d has in practice been materialized so far the findings suggest that contrary to expectations the progress toward electricity market reform is associated with reduced government support to a variety of energy r d activities which threatens sustainable efficiency improvements in the power industry

a 100 year review of electricity policy in ireland 1916 2015 abstract over the past century ireland s electricity sector has undergone a significant transformation this paper documents the nation s struggle to build an electricity system to improve security of electricity supply through portfolio diversification and to promote indigenous energy sources this was a challenge for an electrically isolated island with little natural resources the paper also identifies the ineffective policy decisions that left ireland exposed to the 1970s energy crises the crises did however provide a clear impetus for focusing irish energy policy going forward the successful deployment and integration of large scale wind power was due to strong national and supranational policy decisions in 2015 ireland had the third highest wind energy share of national electricity demand 22 8 of all iea wind member countries the paper also traces ireland s transition through market reform regional fragmentation and looks onwards to the eu internal market for electricity in essence this paper provides a holistic view of the implications of various policy decisions on the electricity sector along with the stresses of external factors on the electricity market and should be useful for policy makers elsewhere faced with similar decisions

demise of the standard model for power sector reform and the emergence of hybrid power markets following earlier reforms in the power sectors of industrialized countries and emerging markets e g chile developing countries were encouraged to unbundle their electricity industries and to introduce competition and private sector participation this paper highlights the developments that led to how power sector reform came to be defined as a standard model and theoretical framework in its own right and how the model was used prescriptively in many developing countries however we also show that after more than 15 years of reform efforts this new industry model has not fully taken root in most developing countries finally we identify and characterize the emergence of new hybrid power markets which pose fresh performance and investment challenges

tax reform and u s economic growth in this paper we evaluate the impact of the tax reform act of 1986 on u s economic growth we first calculate effective tax rates on income from capital employed in corporate noncorporate and household sectors we then project the future growth of the u s economy with and without the 1986 tax reform we find that much of the potential gain in welfare was dissipated through failure to index the income tax base for inflation the most promising avenue for future reform is to include income from household assets in the tax base while reducing tax rates on business income
