factor demand technical change and inter fuel substitution in africa abstract the translog production function has been widely used in applied production analysis due to its flexibility and superiority over other functional forms this study develops a translog production function for a group of african countries the random effects model is estimated using generalized least squares estimator the main findings are first output in africa is driven by a more intensive use of petroleum and electricity and to a lesser extent capital labor and coal relative to technological progress second african production technology exhibits increasing returns to scale suggesting a path towards market entry barriers third technical change is scale biased and factor augmenting albeit very slow fourth all energy inputs are substitutes indicating africa s potential to proportionally switch towards cleaner fuels without adversely affecting economic growth finally and perhaps more generally the study reinforces the assertion that imposing restrictions like homotheticity homogeneity or separability on the production technology is unrealistic and should rather be a testable hypothesis within any applied analysis in view of the documented findings relevant implications for africa are discussed

energy consumption real income and temporal causality results from a multi country study based on cointegration and error correction modelling techniques abstract unlike previous studies on the causal relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multivariate cointegration tests preceded by various unit root or non stationarity tests we test for cointegration between total energy consumption and real income of six asian economies india pakistan malaysia singapore indonesia and the philippines non rejection of cointegration between variables rules out granger non causality and imples at least one way of granger causality either unidirectional or bidirectionial secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample granger exogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total impact of an unanticipated shock to each of the variables beyond the sample period into proportions attributable to shocks in the other variables including its own in the bivariate system results based on these tools of methodology indicate that while all pair wise relationships shared common univariate integrational properties only relationships for three countries india pakistan and indonesia were cointegrated for these countries temporal causality results were mixed with unidirectional causality from energy to income for india exactly the reverse for indonesia and mutual causality for pakistan the vdcs were not inconsistent with these results and provided us with an additional insight as to the relatively more dominant direction of causation in pakistan simple bivariate vector autoregressive models for the three non cointegrated systems did not indicate any direction of causality significantly in either direction

bounds test approach to cointegration and causality between nuclear energy consumption and economic growth in india abstract this paper attempts to examine the dynamic relationship between economic growth nuclear energy consumption labor and capital for india for the period 1969 2006 applying the bounds test approach to cointegration developed by pesaran et al 2001 we find that there was a short and a long run relationship between nuclear energy consumption and economic growth using four long run estimators we also found that nuclear energy consumption has a positive and a statistically significant impact on india s economic growth further applying the toda and yamamoto 1995 approach to granger causality and the variance decomposition approach developed by pesaran and shin 1998 we found a positive and a significant uni directional causality running from nuclear energy consumption to economic growth without feedback this implies that economic growth in india is dependent on nuclear energy consumption where a decrease in nuclear energy consumption may lead to a decrease in real income for a fast growing energy dependent economy this may have far reaching implications for economic growth india s economic growth can be frustrated if energy conservation measures are undertaken without due regard to the negative impact they have on economic growth

the causal relationship between energy use and economic growth in switzerland abstract this paper investigates the relationships between energy consumption and economic growth in switzerland over the period 1950 2010 we apply bounds testing techniques to different energy types separately robustness tests are performed by including additional variables and restricting the analysis to the period after 1970 the results show that there exist robust long run relationships going from real gdp toward heating oil and electricity consumption the relationship between heating oil and gdp is in fact bidirectional although weaker from heating oil toward gdp than in the reverse direction when investigating the period 1970 2010 only the estimate of the long run income elasticity of electricity consumption loses statistical significance and that for heating oil becomes negative those results imply a possible decoupling between gdp growth and energy consumption so that energy conservation policies are not necessarily expected to have a negative impact on swiss economic growth

nuclear energy consumption and economic growth in nine developed countries this article attempts to test the causal relationship between nuclear energy consumption and real gdp for nine developed countries for the period 1971 2005 by including capital and labour as additional variables using a modified version of the granger causality test developed by toda and yamamoto 1995 we found a unidirectional causality running from nuclear energy consumption to economic growth in japan netherlands and switzerland the opposite uni directional causality running from economic growth to nuclear energy consumption in canada and sweden and a bi directional causality running between economic growth and nuclear energy consumption in france spain the united kingdom and the united states in spain the united kingdom and the usa increases in nuclear energy consumption caused increases in economic growth implying that conservation measures taken that reduce nuclear energy consumption may negatively affect economic growth in france japan netherlands and switzerland increases in nuclear energy consumption caused decreases in economic growth suggesting that energy conservation measure taken that reduce nuclear energy consumption may help to mitigate the adverse effects of nuclear energy consumption on economic growth in canada and sweden energy conservation measures affecting nuclear energy consumption may not harm economic growth

the fuelwood market in greece an empirical approach abstract wood has been since ancient times the basic household heating medium nowadays wood remains the primary energy source in rural areas of developing countries mainly in africa in greece the domestic demand of fuelwood is relied mainly on the fuelwood domestic supply especially during the post war period the domestic supply satisfies adequately the domestic demand eliminating the role of imports the present study surveys the long run relationship between the fuelwood prices of different forest species in order to determine the role of the special market conditions in their price formation in addition the error correction model is estimated in order to survey the direction of the granger causality among the prices of the fuelwood forest species the implementation of the impulse response analysis and the variance decomposition confirmed that coniferous and beech fuelwood producer price may account for the volatility of the oak fuelwood producer price this result may contribute greatly to the conservation of oak forest an important carbon storage forest ecosystem

are saving and investment cointegrated the case of malaysia 1965 2003 this article examines whether domestic saving rate leads to higher domestic investment rate in the case of malaysia we argue that the results obtained from cross sectional studies are not able to address this issue satisfactorily and highlight the importance of individual country case studies using the recently developed autoregressive distributed lag bounds testing procedure the results reveal a robust cointegrated relationship between domestic saving and investment rates during the period 1965 to 2003

do employers use unemployment as a sorting criterion when hiring evidence from a field experiment the stigma associated with long term unemployment spells could create large inefficiencies in labor markets while the existing literature points toward large stigma effects it has proven difficult to estimate causal relationships using data from a field experiment we find that long term unemployment spells in the past do not matter for employers hiring decisions suggesting that subsequent work experience eliminates this negative signal nor do employers treat contemporary short term unemployment spells differently suggesting that they understand that worker firm matching takes time however employers attach a negative value to contemporary unemployment spells lasting at least nine months providing evidence of stigma effects

the growth of income and energy consumption in six developing countries this paper reexamines the inter temporal link between energy consumption and income in six developing countries with diverse economic backgrounds and energy statistics in a production function framework we employ the generalized variance decompositions and generalized impulse response techniques to see if the growth of income and energy consumption contains considerable information to predict each other in all countries energy appears as an essential factor of production results indicate that energy may be a relatively more important input than labor and or capital in some countries hence neutrality of energy does not seem to hold

nexus between clean energy consumption economic growth and co2 emissions abstract to investigate the nexus among clean energy consumption economic growth and co2 emissions a newly developed bootstrap ardl bounds test with structural breaks is employed to survey the cointegration and causality for g7 countries we find no cointegration among real gdp per capita clean energy consumption and co2 emissions in canada france italy the us and the uk however cointegration exists in germany when real gdp per capita and co2 emissions serve as dependent variables and in japan when co2 emissions is the dependent variable regarding the results of causality test that we find clean energy consumption causes real gdp per capita for canada germany and the us and co2 emissions causes clean energy consumption for germany besides we find feedbacks between clean energy consumption and co2 emissions for germany and unidirectional causality running from clean energy consumption to co2 emissions for the us our study has important policy implications for g7 countries conducting efficient energy use strategy to reduce co2 emissions

fiscal policy over the real business cycle a positive theory this paper presents a political economy theory of the behavior of fiscal policy over the business cycle the theory predicts that in both booms and recessions fiscal policies are set so that the marginal cost of public funds obeys a submartingale in the short run fiscal policy can be pro cyclical with government debt spiking up upon entering a boom however in the long run fiscal policy is counter cyclical with debt increasing in recessions and decreasing in booms government spending increases in booms and decreases during recessions while tax rates decrease during booms and increase in recessions data on tax rates from the g7 countries supports the submartingale prediction and the correlations between fiscal policy variables and national income implied by the theory are consistent with much of the existing evidence from the u s and other countries

does financial development lead economic growth a vector auto regression appraisal using a vector autoregression var approach several hypotheses are re examined suggested by the literature concerning the relationship between financial development and economic growth investment and productivity the models use quarterly time series data from ten oecd countries and china innovation accounting or variance decomposition and impulse response function analysis is applied to examine interrelationships between variables in the var system and therefore differs from the more usual granger causality approach in particular it examines the relationship between financial development proxied by total credit at best weak support is found for the hypothesis that financial development leads economic growth

modeling the causal linkages between nuclear energy renewable energy and economic growth in developed and developing countries abstract this article investigates the causal relationship between two types of energy variables and economic growth using dynamic simultaneous equation panel data models for 17 developed and developing countries our results indicate that there is a unidirectional causality running from nuclear consumption to economic growth in belgium and spain while a unidirectional causality running from economic growth to nuclear consumption is supported in bulgaria canada netherlands and sweden a bidirectional relationship appears in argentina brazil france pakistan and the usa while no causality exists in finland hungary india japan switzerland and the u k second the results for the second nexus among renewable energy and economic growth show that there is a unidirectional causality running from renewable consumption to economic growth in hungary india japan netherlands and sweden while there exist a unidirectional running from economic growth to renewable consumption in argentina spain and switzerland a bidirectional relationship is supported in belgium bulgaria canada france pakistan and the usa while no causality exists in brazil finland and switzerland third we find the existence of a bidirectional causality between nuclear consumption and economic and a unidirectional causality running from economic growth to renewable energy consumption for the global panel

the effect of unemployment benefits and nonemployment durations on wages abstract we estimate that unemployment insurance ui extensions reduce reemployment wages using sharp age discontinuities in ui eligibility in germany we show this effect combines two key policy parameters the effect of ui on reservation wages and the effect of nonemployment durations on wage offers our framework implies if ui extensions do not affect wages conditional on duration then reservation wages do not bind we derive resulting instrumental variable estimates for the effect of nonemployment durations on wage offers and bounds for reservation wage effects the effect of ui on wages we find arises mainly from substantial negative nonemployment duration effects jel j31 j64 j65

consumer spending during unemployment positive and normative implications using de identified bank account data we show that spending drops sharply at the large and predictable decrease in income arising from the exhaustion of unemployment insurance ui benefits we use the high frequency response to a predictable income decline as a new test to distinguish between alternative consumption models the sensitivity of spending to income we document is inconsistent with rational models of liquidity constrained households but is consistent with behavioral models with present biased or myopic households depressed spending after exhaustion also implies that the consumption smoothing gains from extending ui benefits are four times larger than from raising ui benefit levels

are shocks to renewable energy consumption permanent or transitory an empirical investigation for brazil china and india abstract this paper investigates whether there is a unit root in renewable energy consumption in three large developing economies brazil china and india over the period 1971 2014 to do so it uses four unit root tests assuming one structural break two structural breaks and more than two structural breaks it observes that renewable energy consumption is a unit root process in brazil but it is found as stationary in china and india the paper also tackles issues and challenges in the unit root test methodology in energy economics literature and provides implications for renewable energy consumption in three economies

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

output and substitution elasticities of energy and implications for renewable energy expansion in the ecowas region abstract this study estimates output and substitution elasticities of renewable energy and nonrenewable energy for the economic community of west african states ecowas and discusses implications for expanding the former the results show that nonrenewable energy promises greater benefits for ecowas economic transition with output elasticities averaging between 0 052 0 579 and 0 055 to 0 223 for nonrenewable energy and renewable energy respectively overall estimated technological progress is low 0 5 to 2 6 the bulk coming from input efficiency substitution elasticities 0 02 0 94 suggest potential for switching towards renewable energy notwithstanding scale economics and sitting problems inherent in renewable power generation challenge the opportunities for energy substitution a sustainable policy solution therefore appears to be one favoring scaled and efficient electricity generation from fossil energy in the short run with a gradual switch towards renewable power in the long run in general the applied model provides insights that energy efficiency enhances sustainable growth by propelling technological advancement especially when technical change is scale biased and factor augmenting the study also provides insights that impacts of exogenous shocks to inputs are temporary and hence do not jeopardize efforts aimed at scaling output through increased and efficient use of labor capital and energy especially nonrenewable energy

will affirmative action policies eliminate negative stereotypes a key question concerning affirmative action is whether the labor market gains it brings to minorities can continue without it becoming a permanent fixture in the labor market the authors argue that this depends on how the policy affects employers beliefs about the productivity of minority workers they study the joint determination of employer beliefs and worker productivity in a model of statistical discrimination in job assignments the authors prove that even when identifiable groups are equally endowed ex ante affirmative action can bring about a situation in which employers correctly perceive the groups to be unequally productive ex post copyright 1993 by american economic association

can african countries efficiently build their economies on renewable energy abstract the translog production model is estimated to provide insights on the effectiveness of renewable energy for africa the analysis shows that capital labor renewable energy and nonrenewable energy drive output in african countries with renewable energy being a higher driver of growth than the conventional fossil fuels over the sample period this finding is reflective of the fact that renewable sources like wind hydro and solar account for a greater share of power generation in most african countries output elasticities computed for both energy types reaffirm the results and suggest that eastern and central african countries are more renewable energy dependent than the other three regions in addition technological progress is driven mainly by the efficiency with which various factors and energy inputs are used while africa has great potential of facing out conventional fossil energy the discussion provided in this study suggests that such transition is limited in practice due to issues of scale economics and sitting problems

causal relationship between nuclear energy consumption and economic growth a multi country analysis this paper attempts to investigate the causal relationship between nuclear energy consumption and economic growth using the data from six countries among 20 countries that have used nuclear energy for more than 20 years until 2005 to this end time series techniques including the tests for unit roots co integration and granger causality are employed to argentina france germany korea pakistan and switzerland the main conclusion is that the causal relationship between nuclear energy consumption and economic growth is not uniform across countries in the case of switzerland there exists bi directional causality between nuclear energy consumption and economic growth this means that an increase in nuclear energy consumption directly affects economic growth and that economic growth also stimulates further nuclear energy consumption the uni directional causality runs from economic growth to nuclear energy consumption without any feedback effects in france and pakistan and from nuclear energy to economic growth in korea however any causality between nuclear energy consumption and economic growth in argentina and germany is not detected

information externalities in the labour market and the duration of unemployment a matching model is analysed in which firms imperfectly test workers prior to hiring them if some firms hire only workers who pass the test there is an informational externality unemployment duration is a signal of productivity in equilibrium if it is profitable for a firm to test it is also profitable for it to condition its hiring decision on duration hiring those whose duration is less than a critical value this testing equilibrium is inefficient with too much testing and too low a critical duration value sensitivity analysis of the latter suggests explanations for the dependence of re employment probabilities on duration and the instability of the u v curve

heterogeneity and unemployment dynamics many previous articles have studied the contribution of inflows and outflows to the cyclical variation in unemployment but ignored the critical role of unobserved heterogeneity across workers thi

causality between energy consumption and economic growth in india a note on conflicting results abstract this note examines the different direction of causal relation between energy consumption and economic growth in india applying engle granger cointegration approach combined with the standard granger causality test on indian data for the period 1950 1996 we find that bi directional causality exists between energy consumption and economic growth further we apply johansen multivariate cointegration technique on the different set of variables the same direction of causality exists between energy consumption and economic growth this is different from the results obtained in earlier studies

duration dependence and labor market conditions evidence from a field experiment this article studies the role of employer behavior in generating negative duration dependence the adverse effect of a longer unemployment spell by sending fictitious resumes to real job postings in 100 u s cities our results indicate that the likelihood of receiving a callback for an interview significantly decreases with the length of a worker s unemployment spell with the majority of this decline occurring during the first eight months we explore how this effect varies with local labor market conditions and find that duration de pendence is stronger when the local labor market is tighter this result is consistent with the prediction of a broad class of screening models in which employers use the unemployment spell length as a signal of unobserved productivity and recognize that this signal is less informative in weak labor markets jel code j64

clean energy growth nexus in sub saharan africa evidence from cross sectionally dependent heterogeneous panel with structural breaks abstract this paper examines the existence and nature of a causality relationship between clean energy consumption and economic growth for a panel of eleven sub saharan african countries over the period 1971 2007 we apply the panel unit root test that accounts for the presence of multiple structural breaks 13 and the newly developed panel cointegration methodology which allows for cross section dependence and multiple structural breaks 38 as well as a bootstrap corrected granger causality test the estimation results show that there is cointegration between clean energy consumption and economic growth further the results from the panel causality tests indicate that there is indeed a unidirectional granger causal flow from clean energy consumption to economic growth

training and search during unemployment displaced workers often experience large losses in earnings even a long time after reemployment training programs during unemployment mitigate these losses but also affect the unemployed s willingness to search this paper analyzes how mandatory training programs affect the optimal design of unemployment insurance and how the training intensity should evolve during the unemployment spell the introduction of training reverses the optimal consumption dynamics during the unemployment spell and makes it optimal to incentivize the long term unemployed to find employment despite the depreciation of their human capital targeting training programs towards the long term unemployed however is optimal only if the fall in human capital upon displacement is small relative to the depreciation during unemployment

public policy in a model of long term unemployment this paper considers a model in which the unemployed have to incur a cost to maintain their skills if whether they have done so is not observable the economy has multiple equilibria supported by self fulfilling beliefs on the part of the employers one of these equilibria which we argue is more likely to arise has equilibrium discrimination against the long term unemployed who in response decide to let their skills atrophy as a result in this equilibrium the exit probabilities from unemployment are duration dependent it is shown that equilibrium discrimination survives even if workers are allowed to accept negative wages at the beginning of the employment relation since this equilibrium is highly inefficient constructive government action in the form of positive discrimination subsidies and labour market policies are suggested to correct the market failures however subsidies and positive discrimination by private firms are shown not to have beneficial effects labour market policies in the form of retraining of the long term unemployed are beneficial but reduce the likelihood of a switch to the pareto preferred equilibrium the most useful policy appears to be a limited form of positive discrimination by a government sector

income distribution and co2 emission a comparative analysis for china and india abstract the aim of this paper is to test whether income inequality contributes to environmental degradation in china and india where both countries are giving a great concern about the implications of their unsustainable energy consumption to the environment not only to themselves but also to the global environmental sustainability by applying the bounds test approach to cointegration we found in both countries a long run but not a statistically significant relationship between income inequality and co 2 emissions both in the long run and in the short run the robustness of our cointegration results is also ascertained by using three different long run tests furthermore applying the variance decomposition analysis to examine the dynamic causal relationship between the gini coefficient of income distribution and co 2 emissions we found that income inequality was the least important factor in determining co 2 emissions and that there was no causality running in any direction between co 2 emissions and income inequality in both countries still income and energy consumption are the major determinants of co 2 emissions in both countries nevertheless even though the evidence is not statistically significant in the case of china it indicates that reducing income inequality can have a positive impact on environmental quality while in india redistributing income to improve environmental degradation may not be effective

an international literature survey on energy economic growth nexus evidence from country specific studies in this paper an extensive review of the rapidly growing in the literature on the nexus between economic growth and four types of energy consumption total energy consumption electricity consumption nuclear consumption and renewable consumption the various hypotheses associated with the causal interaction between these variables along with a survey of the empirical literature are also discussed the survey focuses on country coverage periods modeling techniques and empirical conclusions a general observation from these studies that results are found to be sensitive to methodology and type of energy considered the empirical results for the specific countries surveyed show that i for energy consumption growth nexus 29 supported the growth hypothesis 27 the feedback hypothesis 23 the conservation hypothesis and 21 the neutrality hypothesis ii for the electricity consumption growth nexus 40 supported the growth hypothesis 33 the feedback hypothesis and 27 conservation hypothesis iii for the nuclear consumption growth nexus 60 supported the neutrality hypothesis and 40 the growth hypothesis and iv for the renewable consumption growth nexus 40 supported the neutrality hypothesis 40 the conservation hypothesis and 20 the growth hypothesis these mixed results may be attributed to the different used data selected variables and econometric approaches undertaken

literature survey on the relationships between energy environment and economic growth abstract the aim of this study is to exhibit an exhaustive survey which is related to the great flight of the literature of energy environment growth nexus at the individual and regional scale studies covering the period from 1978 to 2014 the survey takes into consideration the sample country region etc periods covering econometric strategies and conclusions our survey is based on the causality direction among i the energy use variables electricity nuclear renewable and non renewable and output growth ii between economic growth and environment and between the three variables at the same time globally these surveys provide paradoxical and not conclusive results which energy consumption can boost economic growth through the productivity enhancement and it can boost also the environmental damages through the enhancement of pollutant emissions our survey sheds more the lights on the energy environment growth literature by giving an extensive listing 1978 2014 of these causal linkages among the energy use variables environment and economic growth for both individual and collective cases there is a unanimous consensus about the importance of dealing with such dynamic relationship which is seems to be a cornerstone element in setting any ambition strategies energy ecological and economics

technology unemployment and efficiency abstract this paper analyzes technology choices and unemployment in search equilibrium in contrast to standard search models the presence of technology choices makes the decentralized equilibrium inefficient there is too little investment in skills too little job creation and there can be multiple equilibria the paper also shows that technological progress is likely to be slower in labor markets where job tenure is low

unemployment and increasing private returns to human capital abstract this paper studies a model of human capital accumulation with real wage rigidity it is shown that the arbitrage condition between hiring a skilled vs an unskilled worker may be stated as a positive relationship between their relative unemployment rates it may be the case that this locus is steep enough to generate increasing returns to education this may lead to multiple equilibria a high education equilibrium may co exist with a low education equilibrium in the former the unskilled are more exposed to unemployment relative to the skilled as compared with the latter the two equilibria cannot be pareto ranked but the latter is preferred to the former by workers while savers prefer the high education one

electricity consumption and economic growth in india abstract this paper tries to examine the granger causality between electricity consumption per capita and gross domestic product gdp per capita for india using annual data covering the period 1950 51 to 1996 97 phillips perron tests reveal that both the series after logarithmic transformation are non stationary and individually integrated of order one this study finds the absence of long run equilibrium relationship among the variables but there exists unidirectional granger causality running from economic growth to electricity consumption without any feedback effect so electricity conservation policies can be initiated without deteriorating economic side effects

energy consumption and economic growth the experience of african countries revisited abstract the aim of this paper is to re examine the causal relationship between energy consumption and economic growth for seventeen african countries in a multivariate framework by including labor and capital as additional variables we apply the variance decomposition analysis due to pesaran and shin pesaran m h and shin y generalised impulse response analysis in linear multivariate models economics letters 1998 58 17 29 to evaluate how important is the causal impact of energy consumption on economic growth relative to labor and capital the results of our multivariate modified granger causality analysis due to toda and yamamoto toda h y and yamamoto t statistical inference in vector autoregressions with possibly integrated process journal of econometrics 1995 66 225 250 tend to reject the neutrality hypothesis for the energy income relationship in fifteen out of the seventeen countries in contrast results of our variance decomposition analyses show that in eleven out of the seventeen countries energy is no more than a contributing factor to output growth and not an important one when compared to capital and labor labor and capital are the most important factors in output growth in fifteen out of the seventeen countries however these results should be interpreted with care as they may not be sufficiently robust enough to support the inference that energy consumption plays a minor role in the economic growth of african countries

energy income causality in oecd countries revisited the key role of capital stock abstract this paper applies a recent advance in panel analysis to estimate the panel cointegration and panel vector error correction models for a set of 22 oecd countries using annual data covering the period 1960 2001 we investigate the relationship between energy consumption and income using an aggregate production function and controlling for the capital stock as well as by exploring the dynamic directions of the causality among these three variables we firstly obtain solid and convincing evidence of a fairly strong long run equilibrium relationship among them secondly it is found that the capital stock is much more productive than energy consumption third it is observed that neglecting the impact of the capital stock on income tends to overestimate the effect of energy consumption finally the panel causality test shows bi directional causal linkages exist among energy consumption the capital stock and economic growth overall the findings reveal that the capital stock plays a critical role in realizing the dynamic relationship between energy and income

does long term unemployment reduce a person s chance of a job a time series test long term unemployed are less likely to leave unemployment than short term unemployed to what extent is this due to an effect of duration and to what extent to heterogeneity on reasonable assumptions heterogeneity on its own with no duration dependence would imply that if over time the exit rate of new entrants fell by a given multiple the overall exit rate from unemployment should fall by the same multiple however over the last twenty years in the uk the overall exit rate has fallen by 60 per cent more than the fall in the exit rate of new entrants another test of pure heterogeneity based on more general assumptions also fails hence we explain the overall fall in exit rates from unemployment by the combined effect of 1 a fall in the ratio of vacancies to unemployed and 2 a higher proportion of the unemployed being long term unemployed and hence demoralized and stigmatized in the eyes of employers

ranking unemployment duration and wages it explores the implication of one central assumption when firms receive multiple acceptable applications they hire the worker who has been unemployed for the least amount of time this assumption ranking is contrasted with the assumption of random hiring no ranking by embodying this assumption in a model of the labour market with job creation destruction and matching the joint behaviour of unemployment the distribution of unemployment durations and wages are characterized the implication that the re employment prospects of employed workers were they to become unemployed are better than those of the currently unemployed appears to have been an important feature of european unemployment experience in the 1980 s this paper examines the effects of the composition of unemployment on wage determination it explores one central assumption when firms receive multiple acceptable applications they hire the worker who has been unemployed for the least amount of time we refer to this assumption as ranking and contrast it throughout to the assumption of random hiring or no ranking by embodying this assumption in a model of the labour market with job creation destruction and matching we characterize the joint behaviour of unemployment the distribution of unemployment durations and wages ranking has a number of important implications first in addition to the obvious result that the exit rate from unemployment is a decreasing function of duration we show that the effect of duration is stronger the higher the rate of unemployment second with the wage depending on the distributions of prospective unemployment durations the presence of long term unemployed per se has little effect on wages third looking at the relation between the wage and the aggregate level of unemployment and comparing ranking to the case of no ranking the wage moves less with the level of unemployment but more with the change in unemployment put simply ranking and no ranking models show exactly the same aggregate unemployment slightly different long run responses of wages to unemployment and sharply different wage dynamics the paper is organized as follows section i characterizes the matching process and derives a matching function based on an urn ball process with vacancies as urns and applications by unemployed workers as balls thus the distribution of applications per vacancy depends on aggregate unemployment and vacancies vacancies with at least one acceptable application are filled when a vacancy receives more than one acceptable application firms use a rule to choose among applicants thus the rule determines who is hired but does not affect the number of hires section ii uses this matching function in a model of the labour market with continual job creation and destruction and characterizes the equilibrium values of unemployment vacancies and hires

the consequences of long term unemployment evidence from linked survey and administrative data that the long term unemployed fare worse in the labor market than do the short term unemployed is well known but why one potential explanation is that the long term unemployed are bad apples wh

affirmative action in a competitive economy abstract we consider a model of endogenous human capital formation with competitively determined wages discrimination is sustainable in equilibrium in the presence of two distinguishable but ex ante identical groups of workers an affirmative action policy consisting of a quota may fail in the sense that there still may be equilibria where groups are treated differently however the incentives to invest for agents in the discriminated group are improved by affirmative action if the initial equilibrium is the most discriminatory equilibrium in the model without the policy the welfare effects are ambiguous it is possible that the policy makes the intended beneficiaries worse off even if the starting point is the most discriminatory equilibrium the expected payoff may decrease for all agents in the target group

nuclear energy consumption oil prices and economic growth evidence from highly industrialized countries this study utilizes the johansen cointegration technique the granger non causality test of toda and yamamoto 1995 the generalized impulse response function and the generalized forecast error variance decomposition to examine the dynamic interrelationship among nuclear energy consumption real oil price oil consumption and real income in six highly industrialized countries for the period 1965 2008 our empirical results indicate that the relationships between nuclear energy consumption and oil are as substitutes in the u s and canada while they are complementary in france japan and the u k second the long run income elasticity of nuclear energy is larger than one indicating that nuclear energy is a luxury good third the results of the granger causality test find evidence of unidirectional causality running from real income to nuclear energy consumption in japan a bidirectional relationship appears in canada germany and the u k while no causality exists in france and the u s we also find evidence of causality running from real oil price to nuclear energy consumption except for the u s and causality running from oil consumption to nuclear energy consumption in canada japan and the u k suggesting that changes in price and consumption of oil influence nuclear energy consumption finally the results observe transitory initial impacts of innovations in real income and oil consumption on nuclear energy consumption in the long run the impact of real oil price is relatively larger compared with that of real income on nuclear energy consumption in canada germany japan and the u s

the effects of unemployment and underemployment on employment opportunities results from a correspondence audit of the labor market for college graduates the authors use data from a resume audit to estimate the impact of unemployment and underemployment on the employment prospects of recent college graduates they find no statistical evidence linking unemployment spells of different durations to employment opportunities by contrast college graduates who are underemployed have callback rates that are 30 lower than those of applicants who are adequately employed the null effects associated with unemployment and the adverse effects associated with underemployment are robust across cities with relatively tight and loose labor market conditions internship experience obtained while completing one s degree substantially reduces the negative effects of underemployment the data support the proposition that employers view underemployment as a strong signal of lower expected productivity

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment

can biomass energy be an efficient policy tool for sustainable development abstract this paper first reviews the potential causality from biomass energy to co2 emissions and economic development within relevant literature later the paper examines statistically the impacts of biomass energy consumption on co2 emissions and gdp in the us to this end paper observes environmental and economic implications of biomass fuel usage throughout energy literature and launches asymmetric causality test to confirm disconfirm the literature output the findings of the tests indicate that biomass energy consumption per capita mitigates co2 emissions per capita and increases gdp per capita eventually upon its output this research asserts that biomass energy consumption can be an efficient policy tool for environmentally sustainable development in the us and that hence biomass production technologies and biomass consumption need to be promoted in other countries as well as in the us on the other hand analyses underline the fact that policy makers should consider as well some potential constraints of biomass energy usage such as land use constraints and carbon leakage from biomass production therefore although this paper explores the remedial impact of biomass on environment and growth one may suggest also that further possible works consider the effects of biomass sources in detail to minimize the some worsening influence of biomass usage on climate change
