productivity effects in brazilian wage determination abstract the article investigates the characteristics of industrial wage determination in brazil using time series data for 22 manufacturing sectors for 1985 1993 the idea is to verify whether changes in sectoral productivity are relevant to explain changes in sectoral nominal wages first we present in a descriptive way the results of a statistical investigation of the data a second more encompassing purpose of the article is an attempt to interpret the results by means of a more elaborate econometric analysis the evidence suggests that rent sharing is indeed a pervasive feature of the brazilian industrial labor market

renewable to total electricity consumption ratio estimating the permanent or transitory fluctuations based on flexible fourier stationarity and unit root tests abstract this paper examines the stationarity properties of the renewable to total electricity consumption ratio for this purpose we use becker et al s 2006 flexible fourier stationarity test as a benchmark and the recent advanced fourier adf unit root test for 90 countries over the period 1980 2011 the results of the first test document the stationarity of the renewable to total electricity consumption ratio for 65 countries from different geographic areas namely africa america asia pacific and europe however when validated the fourier adf test shows that the null hypothesis of unit root is rejected in all the cases except for the united kingdom the fact that the stationarity in the share of renewable to total electricity consumption is documented by the new proposed more powerful tests does not necessarily mean that the renewable energy policies are ineffective as the previous literature states a wide range of elements might influence the stationarity or non stationarity of this ratio however our findings are important from the modeling perspective as the empirical studies on renewable energy can produce reliable results and use appropriate techniques for modeling and forecasting only if the stationarity or non stationarity is correctly documented

an empirical analysis of wage dispersion and efficiency wages the main purpose of this study is to examine inter industry wage differentials in sweden after controlling for individual and job characteristics the results indicate that these differentials are substantial the ranking of the differentials was stable over time while the dispersion of wage premiums fell by 50 per cent during the period 1968 81 a period of strong efforts to reduce wage dispersion in sweden the relation between industry wage premiums and a number of industry characteristics is also examined along with new evidence which is in line with the shirking model hypothesis on the relation between wages and worker control

revisited are shocks to energy consumption permanent or temporary new evidence from a panel suradf approach abstract this paper explores whether the hypothesis of energy consumption stationarity is supported in different regions the stationarity properties indicate that the impact of a reduction in energy consumption or a realignment policy is only temporary and over time the series will revert back to the trend path this paper first applies the panel seemingly unrelated regressions augmented dickey fuller panel suradf test developed by breuer et al breuer j b mcnown r wallace m s 2001 misleading inferences from panel unit root tests with an illustration from purchasing power parity review of international economics 9 3 482 493 which allows us to account for possible cross sectional effects and to identify how many and which members of the panel contain a unit root the main conclusion is that the stationarity of energy consumption will be affected by the differences among the five regions made up of 84 countries during the period 1971 2003 similar conclusions are reached when we analyze country groups based on levels of development moreover the results reveal that conventional panel unit root tests can lead to misleading inferences which are biased towards stationarity even if only one series in the panel is strongly stationary lastly some policy implications emerge from our results

structural breaks and petroleum consumption in us states are shocks transitory or permanent abstract this short communication extends the literature on the stationarity of energy consumption to the case of us petroleum consumption at the state level from 1960 to 2007 the results of lee and strazicich 2003 and narayan and popp forthcoming unit root tests with endogenously determined structural breaks in the intercept and slope of the trend function reveal break dates that correspond to the two opec oil shocks of the 1970s along with the double dip recession of 1980 1982 the null hypothesis of a unit root in petroleum consumption is rejected for a majority of states these results highlight the importance of recognizing the heterogeneity in the behavior of petroleum consumption across states in the formulation of energy conservation and demand management policies

persistence in natural gas consumption in the us an unobserved component model abstract this article re examines the persistence in natural gas consumption using an alternative methodology in particular we report estimates of an unobserved components model in which hysteresis exists if cyclical and natural gas consumptions do not evolve independently in addition this framework is also extended by using the nonlinear approach in which nonlinearities are introduced by allowing past cyclical component to have a different impact on the natural component depending on the regime in a linear framework our results seem to indicate that hysteresis does not exist however when non linearity is taken into account we provide evidence in favor of hysteresis in natural gas consumption when the variations in natural gas consumption are above the threshold value we also selectively survey the empirical literature that examines the long term properties of energy series in order to put our contribution in perspective

assessing the stability of the inter industry wage structure in the face of radical economic reforms we assess the stability of the wage structure in an economy experiencing substantial economic changes we find that the structure of inter industry wage differentials remained remarkably stable in brazil in the face of major shocks

are shocks to disaggregated energy consumption in malaysia permanent or temporary evidence from lm unit root tests with structural breaks abstract the objective of this paper is to examine whether energy consumption in malaysia disaggregated by sector and type is stationary or contains a unit root to realize our objective we apply the lagrange multiplier lm family of unit root tests with up to two structural breaks depending on the decision rule for selecting between results in the no break one break and two break cases we find that energy consumption is stationary for between 50 per cent and 70 per cent of the disaggregated energy series and between 25 per cent and 50 per cent of sectors implications for the malaysian government s attempts to reduce fossil fuel consumption are discussed

are fluctuations in energy consumption transitory or permanent evidence from a fourier lm unit root test abstract in this study we employ a recently introduced unit root test with a fourier function that is capable of capturing the unknown nature of structural breaks to reexamine the stationarity properties of energy consumption per capita of 109 countries over the period 1960 2011 the results of the fourier lagrange multiplier unit root test show that the energy consumption per capita for algeria australia benin bolivia canada costa rica denmark egypt greece guatemala hong kong ireland jordan korea democratic republic mexico myanmar the netherlands new zealand oman paraguay qatar singapore tanzania the united states and vietnam is stationary indicating that energy demand management policies will not be effective on energy consumption in the long term in addition to this since the energy consumption in these countries does not contain a unit root future movements in energy consumption can be predicted by employing historical behaviors

sovereignty and economic development the case of israel and palestine the future permanent economic agreement between israel and palestine will have to determine among other things the trade regime and whether there should be economic borders the decision will have to satisfy goals of economic development including a reduction in economic and social gaps between the two countries and questions of sovereignty we describe and analyse the evolution of the palestinian economy before and since the oslo agreements concerning the future agreement we discuss the tradeoffs between sovereignty and prosperity and argue for the establishment at first of economic borders and a regime of less than full integration

bargaining power mark up power and wage differentials in brazil this paper looks at institutions and economic structures affecting the formation of wages and prices in brazil in particular the author examines the role of collective bargaining and rent sharing between firms and workers these are important elements in explaining two characteristics of the recent inflationary experience in brazil namely the overindexation of wages with respect to past inflation and the positive correlation between the bargaining power of unions and mark up power of firms copyright 1994 by oxford university press

evidence of long memory behavior in u s renewable energy consumption this study examines the degrees of time persistence in u s total renewable energy consumption using innovative fractional integration and autoregressive models with monthly data from 1981 1 to 2010 10 the results indicate that renewable energy consumption is better explained in terms of a long memory model that incorporates persistence components and seasonality the degree of integration is above 0 5 but significantly below 1 0 suggesting nonstationarity with mean reverting behavior the presence of long memory behavior persistence in renewable energy consumption suggests that random shocks may very well move renewable energy consumption from pre determined target levels for a period of time

is per capita electricity consumption stationary time series evidence from oecd countries this study examines the stationary properties of per capita electricity consumption in which the endogenously determined break points are incorporated in 23 high income oecd countries by using annual data over 1960 2005 period we utilize lagrange multiplier lm unit root test that endogenously determines structural breaks in level and or trend we find that 21 country series reject the unit root null hypothesis at the 5 significance level except for 2 country series thus our empirical findings provide significant evidence that per capita electricity consumption is stationary in almost all countries considered in the study the stationarity of per capita electricity consumption indicates that it should be possible for the series to forecast future movements in the energy consumption based on the past behaviors of the series important policy implications emerge from our empirical results of the unit root test with multiple structural breaks

renewable generation and electricity prices taking stock and new evidence for germany and austria abstract economic theory predicts that the increase of renewable electricity production should reduce the price of electricity in the short run which is also known as the merit order effect although the merit order effect is only one of several consequences of renewable production on the electricity system it is crucial to determine its size for the economic evaluation of renewable energies in this paper we present a comprehensive overview of relevant past research results on the price effect of renewables additionally we conduct a new empirical analysis of the price effect of renewable production for the austrian german region a market that clearly qualifies for a merit order effect analysis given its characteristics based on the review and our own analysis we show that the merit order effect varies depending on the region and the assessment method chosen we also find that the size of this effect is less dispersed throughout different markets than previously suggested by the literature

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

applied econometrics and implications for energy economics research abstract developments in applied econometrics particularly with regard to unit root tests and cointegration tests have motivated a rich empirical literature on energy economics over the last decade this study reviews recent developments in time series econometrics applications in the energy economics literature we first consider the literature on the integration properties of energy variables we begin with a discussion of the implications of whether energy variables contain a unit root and proceed to examine how results differ according to the specific unit root or stationarity test employed we then proceed to examine recent developments in the literature on cointegration granger causality and long run estimates between disaggregated energy consumption and economic growth we review both single country and panel studies and pay particular attention to studies which have expanded the literature through adding variables such as financial development and trade in addition to energy consumption to the augmented production function as well as studies which have extended the literature through examining disaggregated energy consumption by type in each case we highlight best practice in the literature point to limitations in the literature including econometric modeling challenges and suggest recommendations for future research a key message of our survey is that the profession needs to guard against overload of research in these areas as most applied studies are no longer adding anything more to what is already known

are fluctuations in electricity consumption per capita transitory evidence from developed and developing economies abstract this paper investigates the unit root properties of electricity consumption per capita of 67 developed and developing countries for the period 1971 2010 to examine the stationary properties of electricity consumption per capita we have adopted lee and strazicich 2003 2004 test of unit root that allows us to test for at most two endogenous breaks and uses the lagrange multiplier lm test statistics results show that 65 country series reject the unit root null hypothesis except for 2 country series thus our empirical findings provide significant evidence that electricity consumption per capita is stationary in almost all countries considered the stationarity of electricity consumption per capita indicates that it should be possible for the series to forecast future movements in the energy consumption based on the past behaviors of the series

consumers willingness to pay for renewable and nuclear energy a comparative analysis between the us and japan abstract this paper examines consumers willingness to pay for nuclear and renewable electricity as two alternatives to fossil fuels for the reduction of greenhouse gas emissions we conduct a choice experiment of consumer stated preferences on the basis of an online survey in four us states and japan after the fukushima nuclear plant accident first the results suggest that us consumers willingness to pay for a 1 decrease in greenhouse gas emissions is 0 31 per month which is similar to the results for the us a decade ago japanese consumers show a slightly lower willingness to pay of 0 26 per month second the average consumer in both countries expresses a negative preference for increases in nuclear power in the fuel mix to a greater extent in japan third renewable energy sources were endorsed by both us and japanese consumers who show a willingness to pay 0 71 and 0 31 per month for a 1 increase in the use of renewable source energy this study also examines the differences in respondents characteristics approximately 60 of the us respondents who did not change their perception concerning the use of nuclear energy subsequent to the fukushima nuclear crisis have almost no preference for variation in nuclear power which is in stark contrast to the japanese respondents opposition to nuclear energy

the role of social capital in financial development to identify the effect of social capital on financial development we exploit social capital differences within italy in high social capital areas households are more likely to use checks invest less in cash and more in stock have higher access to institutional credit and make less use of informal credit the effect of social capital is stronger where legal enforcement is weaker and among less educated people these results are not driven by omitted environmental variables since we show that the behavior of movers is still affected by the level of social capital of the province where they were born

inequality and trust in sweden some inequalities are more harmful than others we present new evidence on the influence of income inequality on generalized trust using individual panel data from swedish counties together with an instrumental variable strategy we find that differences in disposable income and especially differences among people in the bottom half of the income distribution are associated with lower trust the relationship between income inequality and trust is particularly strong for people with a strong aversion against income differentials we also find that the proportion of people born in a foreign country is negatively associated with trust

convergence in energy consumption per capita among asean countries abstract we test for convergence in energy consumption per capita among asean countries over the period 1971 to 2011 using the panel kpss stationarity test and panel lagrange multiplier lm unit root test the results for the panel stationarity and unit root tests with structural breaks find support for energy convergence in asean

renewable energy gathers steam in south africa abstract south africa s renewable energy independent power producers procurement programme the rei4p is an extensive initiative to install 17 8 gw of electricity generation capacity from renewables wind solar biomass biogas and hydropower over the period 2012 2030 although at the outset the rei4p seemed an expensive option designed only to deflect criticism of south africa s high carbon footprint and excessive dependence on coal based electricity generation the escalating costs of the latter the rapidly falling costs of photovoltaic and wind power and the increasingly competitive bidding process of the rei4p have changed this prospect at the conclusion of round three the weighted cost of energy has reached a 23 discount to the cost of new coal based generation and a 28 discount to global renewable energy prices the bidders commitments to local employment creation have similarly increased from 11 to 18 jobs mw the programme is now well placed to deliver on a broad range of objectives including regional development and black economic empowerment however maximum benefit from the rei4p will not be secured without some revision to aspects of the bidding and procurement process more specifically the local content provisions need to be tightened to drive higher levels of local manufacturing

is monthly us natural gas consumption stationary new evidence from a garch unit root test with structural breaks we apply a recently developed unit root test that simultaneously accounts for heteroskedasticity and structural breaks to united states monthly natural gas consumption we find that united states monthly natural gas consumption is stationary our results illustrate the importance of accounting for heteroskedasticity when testing for a unit root in energy consumption with higher frequency data

unions and interindustry wage differentials abstract we investigate the importance of trade unions in collective bargaining in the context of a developing country manufacturing labor market the methodology we adopt to estimate wage differentials follows the method proposed by haisken denew j p and schmidt c m 1997 review of economics and statistics 79 516 521 since it improves on the standard procedure popularized by krueger a b and summers l h 1988 econometrica 56 193 259 our findings indicate that wage dispersion is far greater in the unionized sector of brazilian manufacturing in contrast to evidence from other countries

a re examination of stationarity of energy consumption evidence from new unit root tests abstract in this paper we re examine the stochastic behaviour of per capita total primary energy consumption across 178 countries around the world for this purpose in addition to conventional unit root tests we apply newly developed tests that allow for nonlinear adjustments and structural breaks in the data generating process the results of the unit root tests show that allowing for structural breaks and nonlinearity result in more frequent rejection of the null hypothesis of unit root suggesting that most of the series under consideration follow a stationary process these findings imply that both energy economists and policy makers must be careful and take account of possible nonlinearities and structural breaks in their analyses of energy consumption in addition the results imply that government interventions into the energy markets in most countries have no effect in the long run although the short run effects of the interventions depend on the size and the direction of interventions

retracted experiences in renewable energy and energy efficiency in tunisia case study of a developing country tunisia is one of the few developing countries to have developed a proactive policy for the promotion of renewable energy and energy efficiency already in the mid 1980s this policy gained special momentum starting in the mid 2000s in the context of spiraling international oil prices and the development of a steadily growing energy deficit this momentum resulted in the development of ambitious energy efficiency and renewable energy development programs designed to meet energy requirements in a cost effective manner and to reduce the tunisian economy 0s vulnerability to rising fossil fuel prices the three year 2005 2007 and fouryear 2008 2011 programs as well as the tunisian solar plan are strong indicators of tunisia 0 s

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 economic value of south korea s renewable energy policies rps rfs and rho a contingent valuation study abstract amid growing environmental awareness the diffusion of renewable energy has attracted greater attention from both the public and policymakers to respond to global environmental concerns the korean government implemented a renewable portfolio standard rps in the electric power sector in 2012 it plans to introduce a renewable fuel standard rfs and a renewable heat obligation rho in the transportation and heating sectors in 2015 and 2016 respectively as such this study applies the contingent valuation method to elicit the willingness of korean households to pay more for their energy bills in order to support enforcement of these three policies the analysis considers the economic values of each individual policy as well as the aggregate value at the national level respondents mean willingness to pay for rps rfs and rho are estimated as 3287 5 4432 9 and 3971 1 korean won per month respectively these are equivalent to 5 8 1 5 and 2 0 respectively of current average monthly electricity transportation and heating expenses although all three policies appear highly feasible a cautious approach is necessary given the large proportion of respondents with zero willingness to pay furthermore although the level of willingness to pay for renewable electricity in korea has increased in recent years it remains low when compared to other leading countries such as japan

individual heterogeneity and interindustry wage differentials estimates of interindustry wage differentials are obtained using a fixed effects estimator on a long panel the national longitudinal survey of young men nls after controlling for observable worker characteristics 84 percent of the residual variance of log wages across industries is explained by individual fixedeffects only 16 percent of the residual variance is explained by industry dummies since no controls for specific job characteristics are used job characteristics that vary across industries could potentially explain this rather small residual across industry log wage variance that is not attributable to individual effects clearly then these data do not force us to resort to noncompetitive explanations of interindustry wage differentials such as efficiency wage theory furthermore efficiency wage theories predict that wages in efficiency wage paying or primary industries should be relatively rigid therefore industry wage differentials should widen in recessions however no such tendency is found in the data

inter industry and occupational wage differentials in italy the vast literture on wage determination in the post war era extensively documents the existence of large and persistent wage differentials among industries and workers of comparable skills this paper addresses the issue of wage dispersion in the context of the italian economy the stability over time of industry relative wages confirme previous results obtained for the other countries a wide class of earings equations is estimated using microdata for the italian manufacturing industry the results provide little evidence in support of the view that wage dispersion can be explained by either unmeasured workers charcteristics or by compensating wage differentials conversely the estimated pattern of industry occupation wage differentials is consistent with the existence of rent sharing mechanisms and fairness considerations

the structure of trust in china and the u s this article investigates the structure of trust in china and compares it with the u s using the 2000 and 2005 waves of the world value survey wvs we analyze two dimensions of trust trust in people and trust in major companies it is found that the level of trust has remained stable in china within the 5 year period on the other hand trust in major companies has declined dramatically in u s while trust in people has increased slightly the structure of trust in companies is different from trust in people for both countries individuals with higher education tend to have a higher level of trust individuals who are divorced tend to have lower trust in people individuals who think that other people are fair are more likely to trust in people preference for competition has a positive effect on trust in major companies on the other hand some differences between the two countries are observed perception of fairness does not affect trust in major companies in china while it has a positive effect in u s in year 2006 preference for equality has a negative effect on trust in major companies in u s but no significant effect in china the pattern of trust and its changes over time may reflect differences in market conditions in the two economies

will initiatives to promote hydroelectricity consumption be effective evidence from univariate and panel lm unit root tests with structural breaks abstract this paper examines whether initiatives to promote hydroelectricity consumption are likely to be effective by applying univariate and panel lagrange multiplier lm unit root tests to hydroelectricity consumption in 55 countries over the period 1965 2011 we find that for the panel as well as about four fifths of individual countries that hydroelectricity consumption is stationary this result implies that shocks to hydroelectricity consumption in most countries will only result in temporary deviations from the long run growth path an important consequence of this finding is that initiatives designed to have permanent positive effects on hydroelectricity consumption such as large scale dam construction are unlikely to be effective in increasing the share of hydroelectricity relative to consumption of fossil fuels

time series properties of the renewable energy diffusion process implications for energy policy design and assessment confronted by increasingly tight budgets and a broad range of alternative options policy makers need empirical methods to evaluate the effectiveness of policies aimed at supporting the diffusion of renewable energy sources res rigorous empirical studies of renewable energy policy effectiveness have typically relied on panel data models to identify the most effective mechanisms a common characteristic of some of these studies which has important econometric implications is that they assume that the contribution of res to total electricity generation will be stationary around a mean this paper reviews such assumptions and rigorously tests the time series properties of the contribution of res in the energy mix for the presence of a unit root to that end we use both individual and panel unit root tests to determine whether the series exhibit non stationary behavior at the country level as well as for the panel as a whole the analysis applied to a panel of 19 oecd countries over the period 1990 2012 provides strong evidence that the time series of the renewable share of electricity output are not stationary in 17 of the 19 countries examined this finding has important implications for energy policy assessment and energy policy making which are discussed in the paper
