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

a new look at residential electricity demand using household expenditure data the recent push for a federal energy policy that could substantially change electricity prices in the u s highlights the need to obtain accurate residential electricity demand estimates many electricity demand estimates have been obtained based on the assumption that consumers optimize with respect to known marginal prices but increasing empirical evidence suggests that consumers are more likely to respond to average prices under this assumption this paper develops a new strategy based on gmm to estimate household electricity demand our approach allows a national level demand estimation from publicly available expenditure data and utility level consumption data complementing studies that use individual billing data which are richer yet often proprietary we estimate the price elasticity near 1 which is at the upper end in magnitude among the estimates from previous studies we apply our elasticity estimates in a u s climate policy simulation to determine how these elasticity estimates alter consumption and price outcomes compared to the more conservative elasticity estimates commonly used in policy analysis

modeling industrial energy demand in greece using cointegration techniques abstract this paper attempts to shed light on the determinants of industrial energy demand in greece for this purpose we used cointegration analysis in order to capture short run and long run elasticities for oil and electricity industrial demand respectively the sample spans the period 1970 2004 from the empirical analysis and the johansen s maximum likelihood procedure we found cointegration for oil and electricity demand the results suggest that industrial energy demand is inelastic both in the short and the long run while electricity and oil are substitutes also oil and electricity prices are weakly exogenous both in the short and the long run

new evidence on the impact of structural reforms on electricity sector performance abstract the evolution of electricity industry over the last decades has shown substantial differences between oecd countries this paper empirically investigates to what extent different structural forms of regulation competition and privatisation explain these international differences it distinguishes three modes of electricity performance a net generation per capita b installed capacity and c labour productivity the empirical model spans the period 1975 2011 and uses panel data econometric techniques our analysis reveals that there is a strongly significant interaction impact on the level of electricity performance between regulation and competition the empirical findings do confirm that a robust independent regulatory scheme must be implemented in order to achieve a competitive electricity market

estimation of short run and long run elasticities of energy demand from panel data using shrinkage estimators this article discusses the problem of obtaining short run and long run elasticities of energy demand for each of 49 states in the united states using data for 21 years estimation using the time series data by each state gave several wrong signs for the coefficients estimation using pooled data was not valid because the hypothesis of homogeneity of the coefficients was rejected shrinkage estimators gave more reasonable results the article presents in a unified framework the classical empirical bayes and bayes approaches for deriving these estimators

u s corporate interests and the political economy of trade policy this paper examines the behavior of american corporations with respect to international trade policy initiatives during the 1970s using survey generated data on revealed corporate trade policy interests and firmand industry level data on company characteristics direct or proxy variables were developed and applied in linear regression equations using an ordered probit specification and in an alternative approach using factor analysis to construct a composite dependent variable hypothesized relationships were verified between corporate positions on trade liberalization and the intensity of competition from imports the benefits from improved access to foreign markets and internal risk pooling capabilities of firms firms exposed to the international competitive environment inevitably have a stake in national trade policy this paper explores the revealed behavior of u s corporations on matters of trade policy in the 1970s it develops a set of hypotheses linking corporate trade policy positions to a series of company and industry attributes these hypotheses are tested using survey generated information regarding corporate behavior on trade policy matters beginning with the protectionist burke hartke initiatives of the early 1970s through the post tokyo round period at the end of the decade studies of the political economy of protection typically begin with the proposition that import barriers create rents that can be appropriated by the protected industry the size of the rents to be obtained and their probable division among the various participants in the industry partly determine the intensity of protection seeking behavior lobbying undertaken by participants in the industry brock and magee 1978 the intensity is also influenced by the degree of success expected in the political arena and by imperfections in the lobbying process for instance the incentive to be a free rider on the lobbying efforts of others walter and jones 1981 the actual outcome of protection seeking activity is conditioned by a variety of political considerations as well for instance politicians may be constrained by the possibility of repercussions from groups adversely affected by protection including consumers and export oriented industries foreign competitors are also affected so that issues concerning foreign relations enter into the decision process in addition politicians may be influenced more generally by ideology party platforms or attitudes toward equity a number of researchers including ball 1967 fieleke 1976 clark 1980 and ray 1981a 1981b have verified that a significant positive correlation exists between nominal tariff rates or effective rates of protection across manufacturing industries and low skilled labor intensity taken to be an indicator of the intensity of import competition and thus related to the size of the rents that could be obtained by protection cheh 1974 and bale 1977 analyzed the determinants of the percentage reductions in rates of duty resulting from the kennedy round tariff cuts concluding that the cuts were determined in such a way as to minimize labor adjustment costs see also allen lewis and tower 1980 marvel and ray 1983 also explored the determinants of kennedy round tariff cuts finding the size of tariff cuts tended to be smaller if an industry was more concentrated or sold a larger fraction of its output to household consumers and larger if the industry was more intensive in research and development r d or more highly unionized the result for r d presumably represents the desire at the industry level for improved access to export markets achievable through larger reciprocal reductions in protection on the part of foreign countries along somewhat different lines baldwin 1976 analyzed several key congressional votes on the received for publication november 21 1983 revision accepted for publication december 14 1984 new york university the authors are grateful to robert lipsey robert j levenson j peter jarrett and james green for providing data that contributed to this study to jang ro lee ashok chatterjee and monica kaufmann for research assistance and to bill greene for providing advice on the estimation technique and computer program used to perform the statistical analysis thomas a pugel is also grateful for the support of an esmee fairbaim research fellowship at the university of reading 1 in both studies ray also explores nontariff barriers ntbs across u s manufacturing industries aside from finding a positive relationship between tariff rates and ntbs the results are not easily interpreted however there is some inferential evidence in walter 1971 which finds a significant positive relationship between ntb incidence and presumably relatively low skill intensive developing country exports

what happened to efficiency in electricity industries after reforms the last two decades have witnessed widespread power market reforms in both developed and developing countries that have cost billions of dollars among the key aims and assumptions of these reforms there has always been realization of improvements in power sector efficiency this paper questions the validity of this hypothesis using panel data from 92 countries covering the period 1982 2008 empirical models are developed and analyzed the research findings suggest that the impact of the reforms on electricity industry performance is statistically significant but also limited the results imply that after controlling for country specific variables application of liberal market models in electricity industries slightly increases efficiency in power sector besides we detect a positive relationship between reform process and the percentage share of network transmission and distribution losses in total electricity supplied meaning that as countries take more reform steps the network losses as a fraction of power generated tend to increase moreover the study puts forward that income level and other country specific features are more important determinants of industry efficiency than the reform process overall contrary to expectations of substantial increases in sector efficiency the paper concludes that introducing a decentralized market model with competition in the electricity sector has a limited increasing effect on power industry performance

unprotective tariffs ineffective liberalization and other mysteries an investigation of the endogenous dimensions of trade policy formation in australia 1 introductionsince its formation as a federation in 1901 australia embraced a fairly comprehensive tariff schedule in relation to imported manufactures 1 tariff rates fluctuated considerably over the years however over the course of the century they remained sufficiently high to earn australian manufacturing the reputation of one of the most heavily protected manufacturing sectors in the industrialized world 2 in recent years a number of liberalization waves have surfaced the most notable of these took place in 1973 1977 1988 1991 and most recently in 1994 with the signing of the uruguay round of the gatt agreement still tariffs remain a principal actor in australia s menu of industrial policies in a recent edition of the annual report of the productivity commission 3 published in november 1999 it is noted that although tariffs have dropped considerably since 1994 they remain an important form of assistance tariff assistance still accounts for around 90 of measured effective assistance to the manufacturing sector 4 p 52 given the pervasiveness of australian tariff policy the significant welfare implications of changes in that policy and the particular importance of international trade for this country ensuing from its idiomorphic cultural resource endowment and geographic characteristics 5 considerable research effort has been invested in the examination of various dimensions of this issue at the forefront of pertinent empirical research two items have attracted considerable interest 1 the host of determinants of the highly dispersed tariff concessions and 2 the impact of liberalization on imports research that falls in the category that examines the former including anderson 1980 conybeare 1984 aislabie 1988 and feaver and wilson 1998 is consistent at varying degrees with the theory of endogenous trade policy formation 6 according to the foundations of this theory tariff concessions may be viewed as public outcomes that facilitate a political equilibrium the mechanics are rather elementary when the profit loss that arises from import competition exceeds the transaction cost of a successful lobbying campaign for protection private interests will undertake such lobbying activities the higher the loss from foreign competition the more fervent the lobbying effort hence an increase in import penetration is likely to trigger greater protection7 trefler 1993 p 139 unlike this line of inquiry the critical causal relationship of interest to studies that fall in the category that investigates item 2 including simmons and smith 1994 relates to the effects of tariff changes on imports rather than the reverse the causal directions of the nature examined by studies that investigate issues 1 and 2 are of course not mutually exclusive higher import penetration increases tariffs and higher tariffs in turn decrease import penetration however despite the simultaneity of these variables studies of australia s trade policies associated with research lines 1 and 2 followed separate paths by only considering unidirectional causal relationships and yet these paths do converge the meeting point perplexing results on the one hand studies of endogenous protection such as anderson 1980 and aislabie 1988 have consistently failed to establish the expected result that an increase in import penetration will lead to higher tariffs on the other studies of trade liberalization often find that tariff reduction shave asurprisingly small effect on imports with a study by simmons and smith 1994 concluding that at least in relation to the examined industry removal of the tariff would have no effect on the level of imports p 57 it is important to note that analogous and equally puzzling findings pertaining to improbably smalle ffect so fliberalization on imports have been identified in the caseofothercountries suchastheunitedstates byanumberofauthors

the role of importers and exporters in the determination of the u s tariff preferences granted to latin america abstract this paper investigates the role played by domestic importers and foreign exporters in improving preferential access to the domestic market to this end the framework used in this paper extends the protection for sale analysis to explicitly model the role of domestic importers and foreign exporters in the determination of preferential trade treatment the predictions of the model are tested using data on preferential trade between the united states and latin american countries the results suggest that latin american exporters and us importers lobbying efforts have a significant and important role in determining the extent of preferential access granted by the united states more interestingly these findings also show that u s importers capture a very substantial share of the rents generated by tariff preferences these results therefore shed a pessimistic view on preferential trade schemes as a reliable source of gains for developing countries

real wage growth technical change and competition in the labor market the paper measures the rate of growth of average labor cost and the real wage for the twenty u s two digit manufacturing industries 1948 76 it is argued that these rates of growth give interesting information which other studies on the real wage ignore the results suggest that the gains from technical advance are shared equally across all labor markets consistent with the competitive paradigm a simple and appealing rationale for the observation that high growth industries show the slowest relative rate of growth of prices is also given t he general theory keynes 1936 unleashed many controversies one of the earliest and still topical controversy is the cyclical behavior of the real wage essentially the real wage employment debate has focussed on whether or not the demand schedule slopes downwards and there have been many studies on this topic producing a variety of conflicting findings a common feature of the real wage employment studies is to abstract away from the growth in the real wage that is bound to occur in a growing economy these studies are primarily concerned with deviations from trend or innovations in the real wage and the theme of this paper is that to ignore the growth in the real wage is to throw away valuable and interesting information this information on real wage growth tells us a great deal about competition in the labor market this study should be seen as being complementary rather than conflicting with the real wage employment studies the existence of a downward sloping demand curve for labor is after all not sufficient and probably not necessary for the functioning of competitive labor markets over the span of years 1948 76 i find that individual u s manufacturing industries record widely varying rates of productivity growth however these same industries tend to show a common rate of growth of the real wage this feature of productivity growth was emphasized by the late salter 1960 in his pathbreaking analysis of technical change he writes there is no tendency for above average increases in labour productivity to be accompanied by above average increases in earnings

empirical assessment of the determinants of road energy demand in greece this paper attempts to cast light on the determinants of road energy demand in greece for this purpose we used cointegration techniques and vector autoregression var analysis in order to capture short run and long run dynamics for gasoline and diesel demand respectively from the empirical analysis that covers the period 1978 2003 we find that in the long run gasoline energy demand appears to be price and income inelastic while diesel demand appears to be price inelastic and income elastic we also found that the absence of close substitutes in the road sector denotes the low level of energy switching in greece

the perversity of preferences gsp and developing country trade policies 1976 2000 industrial countries maintain special tariff preferences namely the generalized system of preferences gsp for imports from developing countries critics have highlighted the underachieving nature of such preferences but developing countries continue to place the gsp at the heart of their agenda in multilateral negotiations what effect do such preferences have on a recipient s own trade policies the authors develop and test a simple theoretical model of a small country s trade policy choice using a dataset of 154 developing countries from 1976 through 2000 they find that countries removed from the gsp adopt more liberal trade policies than those remaining eligible the results corrected for endogeneity and robust to numerous alternative measures of trade policy suggest that developing countries may be best served by full integration into the reciprocity based world trade regime rather than continued gsp style special preferences

an econometric analysis of telecom competition privatization and regulation in africa and latin america this paper explores the effects of privatization competition and regulation on telecommunications performance in 30 african and latin american countries from 1984 through 1997 fixed effects regressions reveal that competition measured by mobile operators not owned by the incumbent is correlated with increases in the per capita number of mainlines payphones and connection capacity and with decreases in the price of local calls privatization combined with an independent regulator is positively correlated with telecom performance measures privatization alone however is associated with few benefits and is negatively correlated with connection capacity

energy consumption and economic growth assessing the evidence from greece abstract this paper attempts to shed light into the empirical relationship between energy consumption and economic growth for greece 1960 1996 employing the vector error correction model estimation the vector specification includes energy consumption real gdp and price developments the latter taken to represent a measure of economic efficiency the empirical evidence suggests that there is a long run relationship between the three variables supporting the endogeneity of energy consumption and real output these findings have important policy implications since the adoption of suitable structural policies aiming at improving economic efficiency can induce energy conservation without impeding economic growth

heterogeneous effects of regulation on the efficiency of the electricity industry across european union countries abstract this paper focuses on the relationship between the stringency of regulation oecd indicators and total factor productivity tfp growth in the electricity sectors of 19 european union countries for the period 1994 2007 both the oecd regulatory indicator and the tfp growth index have been decomposed in order to bring to light a complex picture of interrelations in which the negative impact of the overall regulation on productivity is the result of opposite forces estimation results tell us that only the stringency of entry regulation significantly reduces technological change whereas vertical integration exhibits a negative and significant impact only on the catching up process pure efficiency change lastly we found an interesting result concerning the explanatory variables of the scale efficiency change in this case only public ownership matters in other terms high levels of public in the structure ownership of electric companies guarantee improvements in reaching the optimal scale of production these heterogeneous effects are also confirmed when we use a different measure of efficiency that is the distance of the actual from the optimal reserve margin

the kennedy round evidence on the regulation of international trade in the united states the purpose of this paper is to analyze and provide empirical evidence regarding the regulation of international trade flows our goal is to provide an explanation of the changes in the interindustry pattern of trade restrictions which emerged from the kennedy round of tariff negotiations the principal conclusion of the analysis is that the pattern of protection which resulted from the kennedy round was shaped to minimize the domestic political disruption resulting from liberalization industries which faced significant import threats and whose characteristics enhanced their potential political influence were able to maintain tariff protection in the face of overall liberalization the potential impact of the agreed upon tariff reductions was partially undermined by the introduction of offsetting nontariff trade barriers ntbs in addition ntbs were introduced systematically in industries that were becom

the electricity consumption and economic growth nexus evidence from greece abstract this paper attempts to cast light into the relationship between electricity consumption and economic growth in greece in a multivariate framework for this purpose we used cointegration techniques and the vector error correction model in order to capture short run and long run dynamics over the sample period 1970 2011 the empirical results reveal that in the long run electricity demand appears to be price inelastic and income elastic while in the short run the relevant elasticities are below unity we also argue that the causal relationship between electricity consumption and economic growth in greece is bi directional our results strengthen the notion that greece is an energy dependent country and well directed energy conservation policies could even boost economic growth furthermore the implementation of renewable energy sources should provide significant benefits ensuring sufficient security of supply in the greek energy system this evidence can provide a new basis for discussion on the appropriate design and implementation of environmental and energy policies for greece and other medium sized economies with similar characteristics

the impact of special interests on preferential tariff concessions by the united states this paper provides empirical evidence on the rela tive impact of the generalized system of preferences gsp adopted in 1975 and the caribbean basin initiative cbi adopted in 1983 on the pattern of u s imports of manufac tured goods from the target areas at the four digit level in 1984 imports from brazil mexico south america the carib bean basin and from all eligible countries are each analyzed we provide evidence that existing preferential agreements have failed to offset the bias in u s protection against competitive exports from developing countries we also explain why one might have predicted such an outcome

are shocks to energy consumption permanent or temporary evidence from 182 countries this article applies univariate and panel data unit root tests to annual panel data for 182 countries over the period 1979 2000 to examine the stationarity properties of per capita energy consumption the univariate unit root test can only reject the unit root null for 56 countries or 31 of the sample at the 10 level or better however univariate unit root tests have low power with short spans of data and therefore failure to reject the unit root null should be treated with caution when we apply the panel data unit root test we find overwhelming evidence that energy consumption is stationary we discuss the policy implications of these findings and offer suggestions for future research

the impact of regulatory governance and privatization on electricity industry generation capacity in developing economies this article assesses whether a regulatory law and higher quality regulatory governance are associated with superior outcomes in the electricity industry the analysis for 28 developing economies over 1980 2001 draws on theoretical and empirical work on the impact of telecommunications regulators in developing economies controlling for privatization and competition and allowing for country specific fixed effects both regulatory law and higher quality regulatory governance are positively and significantly associated with higher per capita generation capacity this positive impact increases for more than 10 years as experience develops and regulatory reputation grows the results are robust to estimating alternative dynamic specifications including error correction models to inclusion of economy governance political risk indicators and to controlling for possible endogeneity biases the article concludes with a short discussion of causality in panel data modeling of governance models and the policy

industry rent seeking and the filing of unfair trade complaints abstract this paper adopts a rent seeking framework to explain the incidence of antidumping and countervailing duty complaints brought to the u s international trade commission and the department of commerce tobit analysis on all 3 digit sic industries is employed to examine the relationship between the frequency of unfair trade complaints and such factors as industry concentration unionization capital intensity and levels and or changes in employment price cost margins and import penetration large capital intensive industries particularly those facing employment losses and rising import shares are found to be most likely to file complaints protection of quasi rents accruing to capital and labor rather than protection of monopoly returns appears to be the primary impetus behind the filing of unfair trade complaints

the political economy of international trade enduring puzzles and an agenda for inquiry a similar set of concepts has been central to the literatures on the formation of trade policy coalitions and the new economics of institutions the political and economic consequences of the degree to which assets are specific to a particular economic activity in this survey the authors take the necessary first step of summarizing the main findings of these two literatures and then suggest ways in which the issue might be joined in addition to providing a more coherent understanding of the findings of these two literatures and some new directions for them the authors show that many puzzles remain in the field of trade politics puzzles for which there are no appealing answers or where there are answers no strong evidence in support of them this essay then in addition to being a theoretical review of the literature puts forward an agenda for future study of international trade politics

capturing the impact of shocks on the electricity sector performance in the oecd abstract this paper focuses on the responses of electricity performance to shocks arising from structural reform policies with a dynamic panel vector autoregression pvar model that allows endogeneity we decompose the responses of electricity performance measures to shocks generated by the inclusion of structural reform indicators capturing the effect of competition regulation and privatization the sample spans the period from 1975 to 2011 including 30 oecd countries the empirical findings do confirm that a robust independent regulatory scheme must be implemented in order to achieve a competitive electricity market finally the dynamic pvar results using impulse response functions and variance decomposition analysis further support the validity of these results

electricity prices and public ownership evidence from the eu15 over thirty years abstract this paper studies the impact of corporate ownership on residential net of tax electricity prices when the ownership effect is separated from the liberalisation effect and from other drivers of change after a discussion of a simple conceptual model and of earlier literature we use iea and oecd data for the eu15 over nearly three decades panel econometrics suggests that after controlling for other factors public ownership is associated with lower residential net of tax electricity prices in western europe the impact of liberalisation on prices is smaller and more uncertain

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time
