increasing consumer participation rates for green pricing programs a choice experiment for south korea abstract this study examines the factors that can increase consumer participation rates in green pricing programs by conducting a choice experiment in south korea estimation results were obtained from a conditional logit conditional logit with interaction terms random parameter logit random parameter logit with correlation and individual level coefficient models a novelty of our analysis was the consideration of monetary and non monetary incentives as factors influencing consumer uptake in green pricing programs the estimation results show that increased consumer participation in green pricing programs is positively linked with green energy sources that produce fewer externalities more jobs and monetary incentives such as tax credits or green mileage however there is an inverted u shaped relationship between participation rates and the share of green electricity in total electricity supply mean willingness to pay for fuel cells is highest followed by solar and wind energy estimation from the random parameter logit with allowing for correlations among random coefficients of attributes reveals that consumers are divided into green pro environment consumers and blue growth oriented consumers green consumers prefer a higher green electricity share solar or fuel cell to wind a greater proximity of green power plants to their homes and green mileage or green parks to tax credits in comparison blue consumers favor a lower green electricity share green power plants that are far from their homes and monetary incentives rather than non monetary incentives the results of this study suggest guidelines for the design of successful green pricing programs green pricing programs that are designed with information on types of green energy sources consider the distance of power plants to consumers residences focus on the share of green electricity and incorporate monetary incentives are likely to have increased consumer participation rates

the effectiveness of fiscal and monetary policy responses to twin crises we study how effective fiscal and monetary policy responses are during a twin crisis using the dataset provided by laeven and valencia 2008 we identify 57 episodes of twin crises following the methods proposed in baldacci et al 2009 and hutchison et al 2010 we construct the variables measuring the duration and output cost of a twin crisis we find that fiscal policy does not seem to be associated with the shortening of a twin crisis regarding monetary policy we find that monetary tightening is associated with the lengthening of a twin crisis duration consistent with the result in hutchison et al 2010 dealing with a sudden stop crisis in addition our results show that while a mild monetary expansion is effective in reducing a twin crisis duration over expansionary monetary policy loses its effectiveness

effects of fiscal contractions the importance of preceding exchange rate movements we examine the importance of exchange rate and money supply movements for the macroeconomic outcome of fiscal contractions and find i contractions associated with a favorable macroeconomic outcome have been preceded by significantly higher real depreciations as compared to contractions associated with a less favorable macroeconomic outcome and ii contractions preceded by real depreciations improve expectations about future income and generate higher private consumption growth we discuss policy implications for countries both outside and inside the emu

fiscal adjustments and their effects during the transition to the emu the transition phase to emu hasbeen accompanied by considerable monetaryand fiscal consolidation efforts in the eu this paper analyses this consolidationprocess and its effects on economicactivity in the eu it is tested to what extent fiscal retrenchment efforts havedepressed or stimulated private spending inthe case of the latter non keynesian effectsdominate the traditional keynesianexpenditure effects of government spending taxation and transfer payments

tales of fiscal adjustment fiscal adjustments why they can be expansionary this paper examines the evidence on fiscal adjustments in oecd countries from the early 1960s to today the results shed light on the recently observed phenomenon of fiscal tightening that produces non keynesian expansionary effects one interpretation is that a serious fiscal tightening increases demand wealth rises when future tax burdens decline and when interest rates decline credibility is restored and inflation or default risks abate both consumption and investment rise for this effect to produce an expansion the tightening must be sizeable and occur after a period of stress when the budget is quickly deteriorating and public debt is building up another interpretation emphasizes the supply side typically a fiscal consolidation based on tax increases is short lived to be long lasting it must include cuts in public employment transfers and government wages to be politically possible such a policy must be supported by trade unions these measures result in more efficient labour markets and boost the supply side based both on statistical evidence and on a detailed analysis of ten cases of major fiscal adjustment this article provides cautious support to the supply side view without denying a more limited role for the demand side channel alberto alesina and silvia ardagna

racial disparity in unemployment abstract in the united states black workers earn less than their white counterparts and have higher rates of unemployment empirical work indicates that most of this wage gap is accounted for by differences in cognitive skills that emerge at an early age in this paper we demonstrate that the same is not true for black white disparity in unemployment a large unexplained unemployment differential motivates the paper s second contribution a potential theoretical explanation this explanation is built around a model that embeds statistical discrimination into the subjective worker evaluation process that lies at the root of the efficiency wage theory of equilibrium unemployment

the new open economy macroeconomics of government debt in this paper we introduce an overlapping generations structure of the blanchard type in a new open economy macroeconomics model this allows us to study a wider range ofscal shocks compared to the traditional mundell fleming and to the baseline redux models one important policy implication of our model is that the tax cut imple mented in the us in 2001 might have contributed to the appreciation of the dollar vis a vis the euro in contrast the imposition ofscal constraint such as the golden rule proposed by the uk government can have opposite exchange rate e ects

the welfare state and competitiveness in all industrial countries fiscal policy is increasingly about redistribution in this paper the authors study redistribution across different types of agents in a world characterized by the presence of labor unions and distortionary taxation they show that an increase in transfers financed by distortionary taxation has nonlinear effects on unit labor costs relative to the other countries depending on the degree of centralization of the wage setting process in the labor market the authors find considerable empirical support for the model in a sample of fourteen oecd countries copyright 1997 by american economic association

why are stabilizations delayed when a stabilization has significant distributional implications e g tax increases to eliminate a large budget deficit socioeconomic groups may attempt to shift the burden of stabilization onto other groups the process leading to stabilization becomes a war of attrition each group attempting to wait the others out and stabilization occurring only when one group concedes and bears a disproportionate share of the burden the authors solve for the expected time of stabilization in a model of rational delay and relate it to several political and economic variables they motivate this approach and its results by comparison to historical and current episodes copyright 1991 by american economic association

money demand and the effects of fiscal policies this paper reexamines the choice of the scale variable in the money demand function a variety of evidence suggests that consumer spending is a better scale variable than gnp changing the money demand specification along these lines can profoundly affect the standard keynesian analysis of a tax cut copyright 1986 by ohio state university press

discrimination fact or fiction an examination using an alternative approach women earn less than men blacks earn less than whites these facts are blatantly observable in the economy with the proliferation of civil rights legislation in the last two decades social scientists have become increasingly concerned with the determination of the wage gap attributable to discrimination because workers have different productivities statistical methods have been used to isolate the discrimination effect from wage differences justified by differences in productivity the primary method estimates an equation with wages expressed as a function of productivity and sex or race since productivity cannot be directly observed a number of proxies for productivity have been used such as education tenure and experience statisticians 11 have shown that the necessity of using proxies results in statistical biases which may tend to overestimate discrimination they have shown that mismeasuring any independent variable can impart a bias on each regression coefficient thereby causing a severe misestimate of discrimination these errors are proportional to the degree of mismeasurement the relative degree of error variance in the independent variables as well as to the amount of intercorrelation between each variable and race or

useful government spending direct crowding out and fiscal policy interdependence this paper introduces perfect substitutability between private and public consumption in a dynamic open economy with imperfect competition and nominal rigidities this implies a direct crowding out effect that generalising to the two country case some well known properties of a closed economy tends to reduce consumption following both domestic and foreign expansions a less expected result is that sub stitutability has a positive effect on the short run output spillover we also show that if we modify the model to allow for home bias in government spending temporary fiscal expansions display a quasi neutrality property

citizen versus consumer challenges in the uk green power market abstract this paper investigates the potential advantages and disadvantages of green power products as opposed to the traditional fossil fuel levy which was the uk s chosen tax regime as a means of developing renewable energy in the uk willingness to pay for electricity generated from renewables is investigated results indicate that willingness to pay varies with social status and income however results demonstrate that there is a significant minority in full support of some sort of fiscal initiative electricity generated from renewables is a concept supported by the majority however given the stated willingness to pay it is unlikely that any new renewable capacity will result from green tariff schemes in the near term it is concluded that the green citizen must continue to co exist with the green power purchaser if the uk is to make any significant improvement in the contribution of renewable energy to electricity demand the authors would like to acknowledge the support of irene lorenzoni and jane powell of the centre for social and economic research on the global environment university of east anglia leicester energy efficiency advice centre and leicester energy agency

willingness to pay lip service applying a neuroscience based method to wtp for green electricity abstract consumers willingness to pay wtp represents a central question for providers of renewable energy most studies on the subject have used contingent valuation and choice experiments however all empirical designs employed to date suffer from serious biases such as strategic behavior we introduce a novel neuroscience based approach to renewable energy related wtp research neuropricing which eliminates some of these biases we tested consumers wtp for two different green electricity products and found wtp for these products to be about 15 above that for a non green electricity tariff our results suggest that neuropricing is indeed able to eliminate strategic behavior moreover this approach allows for wtp studies with much smaller sample sizes than traditional methods require the neuroscience methodology can be used by researchers and marketers alike not only for testing the effects of product attributes on wtp but also for evaluating wtp effects of specific messages in marketing communications thus it may lead to a better understanding of consumer behavior and hence facilitate more successful marketing of renewable energy

the macroeconomic effects of monetary and fiscal policy in a small open economy does the exchange rate regime matter abstract this paper develops a small open economy model in the spirit of obstfeld and rogoff 1995 the introduction of endogenous traded sector output unlocks current account and real exchange rate effects within this framework where specific consideration is given to the case with fixed but adjustable parities exchange rate devaluation generates similar qualitative effects as a money supply expansion under floating rates output and external effects of government spending shocks are broadly consistent with the adjusted basic non micro founded mundell and fleming mf framework but differ in significant ways from the baseline mf model contrary to the textbook mf model a government expenditure shock depreciates the nominal exchange rate and generates real effects under the fixed rate system

fiscal consolidation under fixed exchange rates abstract we present the fixed exchange rate version of the obstfeld and rogoff model and analyze the international transmission of fiscal policy shocks the welfare effects of an unanticipated contraction in government expenditure in the home country are shown to depend crucially on the way in which world money stock is set if home authorities alone are responsible for pegging the exchange rate a fiscal adjustment leads to a decrease in the real interest rate stimulates private consumption and limits the contraction in world output compared with a situation in which a cooperative scheme is implemented the model is then used to propose a new interpretation of recent events in the eu countries that have enacted restrictive fiscal policies while pegging their currencies to the dm

welfare and macroeconomic interdependence we develop a baseline model of monetary and fiscal transmission in interdependent economies the welfare effects of expansionary policies are related to monopolistic supply in production and monopoly power of a country in trade an unanticipated exchange rate depreciation can be beggar thyself rather than beggar thy neighbor as gains in domestic output are offset by deteriorating terms of trade smaller and more open economies are more prone to suffer from inflationary shocks larger economies benefit from moderate demand led expansions but may be worse off if policy makers attempt to close the output gap fiscal shocks are generally beggar thy neighbor in the long run in the short run they raise domestic demand at given terms of trade thus reducing the welfare benefits from monetary expansions analytical tractability makes our model uniquely suitable as a starting point to approach the recent new open economy macroeconomic literature

us consumers willingness to pay for green electricity abstract we analyze us consumers demand for environmental attributes of deregulated residential electricity services using results from a survey designed to elicit consumers willingness to pay for such attributes and using results from a hedonic analysis of actual price premiums charged for green electricity in several deregulated markets survey results suggest that many population segments are willing to pay for decreased air emissions even if there is no alteration in fuel source furthermore several groups are willing to pay significantly more when emissions reductions stem from increased reliance upon renewable fuels the hedonic analysis suggests that several product features not considered in the survey help explain real price premiums including fuel mix from newly created renewable generation capacity green e certification brand name and state of offer while survey and hedonic results are not easily compared due to limitations of the survey both point to similar values for key environmental attributes though the survey results are likely to overstate actual willingness to pay in sum the results suggest that consumer driven purchases can in part support the future of renewable generation capacity in the united states though reliance upon other policy alternatives may be needed if energy prices spike

why do minority men earn less a study of wage differentials among the highly educated en in several minority groups in the united states have wages that are substantially lower than those of the benchmark majority group non hispanic white men several generations of labor economists have sought to understand the forces that drive these disparities this research program is potentially important for the purpose of determining whether minority wage gaps are likely to be narrowed more effectively by increasing enforcement of antidiscrimination laws or by implementing policies that reduce inequity in educational opportunity existing work shows large racial and ethnic differences in premarket factors especially formal schooling and suggests that these differences play a key role in shaping wage differences one example is trejo 1997 who finds that third and higher generation mexican american men earn 21 less than non hispanic white men approximately three quarters of the earnings gap is found to be attributable to the mexican americans relative youth and to differences in english language proficiency and years of schooling a second example is neal and johnson 1996 who find that black men earn 24 less than do non hispanic white men differences in schooling account for only about one fifth of this gap when the authors condition on performance on a basic verbal and math skills test the armed forces qualification test afqt though the differential between wages of blacks and whites declines to approximately onethird of its unadjusted level 1 trejo s 1997 study is a nice example of the traditional approach to studying race ethnicity wage gaps traditional in the sense that the explanatory variables in the study are conventional objective measures of human capital such as years of schooling and language ability neal and john

stuck between a roc and a hard place barriers to the take up of green energy in the uk abstract this paper examines the uk mechanisms for ensuring future investment in renewable energy through consumer adoption of green energy tariffs and the renewable obligation certificate roc system using a national survey and focus groups the stated willingness by uk customers to pay a premium for renewable or green energy and actual take up of such tariffs is assessed substantial differences between willingness to pay for and the adoption of green energy tariffs are reported this disparity is linked to a range of factors including consumer confusion lack of supply complexities of constructing green source tariffs under the roc system and a lack of customer trust it is concluded that the re definition of the green energy market in favour of green source tariffs greater direct compliance with the renewable obligation by addressing supply constraints and efforts in providing clearer information and choices for consumers via a compulsory green energy accreditation scheme are required if willing consumers are to contribute to investment in renewable energy

fiscal crises and aggregate demand can high public debt reverse the effects of fiscal policy abstract this paper shows how the power of fiscal policy to affect consumption can vary depending on the level of public debt at moderate levels of debt fiscal policy has the traditional keynesian effects current generations of consumers discount future taxes because they may not be alive when taxes are raised or there will be a larger population available to pay the taxes but when debt reaches extreme values current generations of consumers know there is a high probability that they will have to pay extra taxes a fiscal deficit can have a contractionary effect in these situations

fiscal policy in good times and bad in the 1980s several countries with large government debt or deficit implemented substantial and in some cases drastic deficit cuts contrary to widespread expectations in many cases private consumption boomed rather than contracted this paper shows that in times of fiscal stress shocks to government revenues and especially expenditure have very different effects on private consumption than in normal times

inflationary consequences of anticipated macroeconomic policies budget deficits implying an unbounded present value of government debt are infeasible and hence induce expectations of a future policy change we study how expectations of a policy switch whose timing or mix between expenditure cuts tax increases or increases in money growth rates may be uncertain affect economic dynamics before the switch takes place we are especially concerned with the correlation between changes in the deficit and inflation of particular interest is our finding that timing uncertainty may induce fluctuations in the rate of inflation that seem to be unrelated to the budget deficit at a time when the budget deficit is responsible for inflation

does it matter who responded to the survey trends in the u s gender earnings gap revisited studies have shown a decreasing trend in the u s gender earnings gap since the 1980s the authors work with a framework established by blau and kahn 1997 jole 2006 ilrr who used the michigan panel of income dynamics psid to decompose that gap into observable and unobservable components in order to determine which contributing factors are gender specific and which can be attributed to the wage structure they extend the blau and kahn framework to consider measurement error due to the use of proxy representative respondents of the survey s earnings variable first they find a trend toward more females in the gender composition of the household respondents and second they estimate the impact of that change on blau and kahn s decomposition they determine that some of the changes in the gender earnings gap could actually be attributed to whether the surverys were self or proxy responded that is the actual reduction in the gender pay gap may be smaller than what the estimates without taking into account the measurement error might indicate the authors suggest the need for a careful validation study to ascertain the extent of the spurious measurement error effects

determinants of green electricity tariff uptake in the uk a number of countries offer domestic consumers the option of buying their electricity supply through a green tariff whereby the supplier typically guarantees that all or part of the supply has been generated using renewable energy sources previous studies that have sought to identify variables predicting why consumers choose to purchase a green tariff have utilized surveys specifically about the topic this study builds on previous work by reviewing the uk market using data from the understanding society survey a general survey of households which should be free from framing or focalism concerns in addition this data includes variables that to the authors knowledge have not been tested through other work results find that individuals in the highest income quartile those with higher qualifications those supporting the green political party and those exhibiting strong environmental behaviour were all more likely to have purchased green tariffs significant to a lesser degree were strong environmental attitudes and those households with some form of renewable energy technology installed

what makes people seal the green power deal customer segmentation based on choice experiment in germany abstract consumers have the power to contribute to creating a more sustainable future by subscribing to green electricity tariffs in order to reach consumers beyond the eco niche identifying the drivers that positively influence the adoption of green electricity is of fundamental importance this paper examines various factors that help to explain the extent to which green electricity subscribers differ from those that display strong preferences towards green electricity but have not yet walked the talk by making use of a latent class segmentation analysis based on choice based conjoint data this paper identifies three groups of potential green electricity adopters with varying degrees of preference for renewable energy findings indicate that socio demographic factors play a marginal role in explaining the differences between green electricity subscribers and potential adopters with the exception that actual adopters tend to be better educated analysis of psychographic and behavioral features reveals that adopters tend to perceive consumer effectiveness to be higher place more trust in science tend to estimate lower prices for green electricity tariffs are willing to pay significantly more for other eco friendly products and are more likely to have recently changed their electricity contract than non adopters policy recommendations associated with these findings are provided

trigger points and budget cuts explaining the effects of fiscal austerity we propose and solve an optimizing model which explains counterintuitive effects of fiscal policy in terms of expectations if government spending follows an upward trending stochastic process which the public believes may fall sharply when it reaches specific trigger points then optimizing consumption behavior and simple budget constraint arithmetic imply a nonlinear relationship between private consumption and government spending this theoretical relation is consistent with the experience of several countries jel e62 e21 textbook aggregate demand models suggest simple relationships between the government budget and economic activity a cut in the government deficit for example depressing consumption and output though such models heavily influence the design of stabilization policies their micro foundations are unclear and their sharp predictions are not always consistent with reality in many countries large cuts in government spending carried out as part of stabilization programs have led to expansions rather than contractions in economic activity the absence of simple relationships be

response error and the union wage differential broad variation in estimates of the union wage gap has perplexed labor economists one specification error that is consistent with the observed variation is measurement error in reported union status this article applies results of bollinger 1996 to estimate a range for the union wage gap both a cross sectional model and a fixed effects model are estimated in order for the true coefficient in the fixed effects model to be bounded below the true coefficient in the cross sectional estimates measurement error would have to be less than 0 8 the difference between the fixed effects estimates and the cross sectional estimates is primarily due to measurement error rather than to unobserved heterogeneity an examination of differences in returns to union membership by industry occupation and educational level shows that these differences are largely robust to measurement error many of these differences would be found even if error rates were as high as 10 or more an array of empirical estimates for the union wage differential has resulted from the variety of approaches to estimation lewis 1986 reviews the vast literature that attempts to estimate the union wage effect two extremes are represented by mincer 1983 who estimates the wage differential to be 0 01 while farber 1990 reports an estimate of 0 26 clearly specification error is the root cause of these differences the literature has focused upon unobserved heterogeneity in worker status as the main specification error frequently estimation approaches based on within estimators applied to fixed effects models using panel data are used to account for the possibility of unobserved heterogeneity as would be predicted by unobserved heterogeneity lewis 1986 p 94 reports that the panel wage gap estimates surveyed in the chapter on the average are roughly half as large as the corresponding cross section estimates this is often taken as evidence for bias in the cross section estimates due to the presence of fixed effects however these results are also consistent with measurement error in the report of the union status indeed chapter 5 in lewis 1986 focuses upon this possibility the difference might be the result of union status measurement error p 94 this article applies results of bollinger 1996 to compare the effect of measurement error on cross sectional estimates and panel estimates of the union wage differential bollinger 1996 establishes bounds for the slope coefficients of a linear regression when a binary regressor is thought to have measurement error the results here do not identify a point estimate of the union wage differential they relax many of the assumptions that are required to obtain the point estimates these bounds serve the purpose of sensitivity analysis as called for by leamer 1985
