allowance price and distributional effects under a personal carbon trading scheme abstract personal carbon trading pct is a downstream cap and trade scheme to reduce carbon emissions from the household sector in comparison to an upstream carbon trading scheme pct is a progressive scheme in which the poorer consumers are mostly winners as their levels of emissions are generally lower this paper investigates the equilibrium price for allowances and distributional effects under a pct scheme first we propose an equilibrium model for pct from which we derive an equilibrium price for allowances second a consumer surplus analysis is conducted to examine the welfare changes caused by the pct scheme generally we find that the pct scheme is progressive and can provide a buffer between the energy and allowance price based on these results the implications are discussed and suggestions for a future study are provided

interprovincial migration and local public goods the objective of this paper is to test whether fiscally induced migration occurs in canada that is whether interprovincial migration flows are influenced by government tax and expenditure policies in order to do so a multinominal logit model of migration is developed in which individuals choose to live in the province where their utility would be highest the model is estimated using aggregate data for the period 1962 81 the results indicate that migration is influenced by provincial government spending trough the magnitude and direction of the effect differs with the type of government spending the implication of these results is that intergovernmental transfer payments and provincial natural resource revenues also have the potential to influence migration flows in canada summary in fre excerpt

the interprovincial migration of canadian physicians does income matter this study applies a multinomial logit model of human capital migration to examine the factors influencing the movement of physicians within canadian provinces between 1976 and 1992 the empirical investigation covers general practitioners and specialists it excludes interns residents between seven regions atlantic canada quebec ontario manitoba saskatchewan alberta and british columbia the results suggest that differences in real income have a positive and significant effect on a physician s decision to migrate form one province to another provinces with the highest after tax income highest expenditure per physician and highest fee per service rates have the highest net rate of in migration income differences are however not the only factor influencing a physician s choice to move working conditions within a province which we proxy with the number of hospitals beds and health expenditures per capita are also important factors likewise the ratio of rural to urban population distance b

outsourcing retail pricing to a category captain the role of information firewalls it has been argued that retailers lack both the resources and capabilities to maximize category performance retailers may seek category management cm advice from a manufacturer referred to as a category captain cc a cc s recommendations affect all brands in the category not just her own despite an increase in the number of cc collaborations retailers are still concerned about manufacturer opportunism and militant behavior by manufacturers not selected as ccs whereas government agencies are worried about anticompetitive behavior that could harm consumers the federal trade commission recommends strictly enforced information firewalls within a cc s organization as a best practice guideline in this study we develop an empirical model and use policy simulations to quantify the impact of cc arrangements with information firewalls on retailers manufacturers and consumers we show how these effects could be influenced by the deactivation of vertical and horizontal information firewalls within the cc s organization

exchange rates and cash flows in differentiated product industries a simulation approach how do exchange rate changes impact firms cash flows we extend a simulation method developed in industrial organization to answer this question we use prices quantities and product characteristics for differentiated products coupled with a discrete choice framework and an assumption of price competition to estimate marginal costs for all producers using a monte carlo approach we generate counterfactual prices and profits for different levels of exchange rates we illustrate the method using the market for bottled water our results stress that even in a relatively simple market such as this one different brands face very different exchange rate risks consider a firm that produces a good in france using mainly local inputs and sells it abroad in locations that have a floating exchange rate vis a vis the euro profits and in turn the value of the firm are potentially exposed to exchange rate changes if the euro appreciates profits when measured in euros are likely to decrease how large is the decrease in profits similarly what is the impact of such an exchange rate change on the profits of an import competing firm these are the questions that a large literature on exchange rate exposure attempts to answer

additional information for comments on alternative models of demand for automobiles by charlotte wojcik abstract in a recent paper in this journal econ lett 68 2000 113 wojcik argues that the nested logit is likely to be superior to demand specifications we and others have used in recent empirical work we review the relevant models and their uses consider her application and find that her conclusions are incorrect

product differentiation cost reducing mergers and consumer welfare cost synergies are an explicitly recognized justification for a two firm merger and empirical techniques are now widely used to assess the impact of cost reducing mergers on prices and welfare in the post merger market we show that if the merger occurs in a vertically product differentiated market then the merger will lead to a reduction in product offerings that limits the usefulness of pre merger empirical estimates indeed we further show that in such markets two firm mergers will typically lead to higher prices regardless of the merger s cost savings jel classifica tion l10 l41 differentiation des produits fusions pour reduire les couts et bien etre du consommateur les synergies de couts sont une justification explicitement reconnue pour la fusion de deux firmes et il existe des techniques empiriques vastement utilisees pour mesurer l impact des fusions visant areduire les couts sur les prix et le niveau de bien etre dans le marcheapres la fusion on montre que si la fusion se produit dans un marchede produit differencieintegreverticalement alors la fusion reduit l even tail de produits ce qui limite l utilitedes estimations empiriques faites avant la fusion de plus on montre que dans de tels marches les fusions de deux firmes finissent par engendrer des prix plus eleves quelles que soient les reductions de couts auxquelles on en arrive

optimal intensity targets for greenhouse gas emissions trading under uncertainty uncertainty is an obstacle for commitments under cap and trade schemes for emission permits we assess how well intensity targets where each country s permit allocation is indexed to its future realized gdp can cope with uncertainties in international greenhouse emissions trading we present some empirical foundations for intensity targets and derive a simple rule for the optimal degree of indexation to gdp using an 18 region simulation model of a cooperative global cap and trade treaty in 2020 under multiple uncertainties and endogenous commitments we show that optimal intensity targets could reduce the cost of uncertainty and achieve significant increases in global abatement the optimal degree of indexation to gdp would vary greatly between countries including super indexation in some advanced countries and partial indexation for most developing countries standard intensity targets with one to one indexation would also improve the overall outcome but to a lesser degree and not in all individual cases although target indexation is no magic wand for a future global climate treaty gains from reduced cost uncertainty and the potential for more stringent environmental commitments could justify the increased complexity and other potential downsides of intensity targets

china s 2020 clean energy target consistency pathways and policy implications abstract china has proposed its 2020 clean energy target together with the climate change target of reducing co2 intensity of the economy by 40 45 below the 2005 level this article investigates the feasibility of these targets by testing their consistency under possible economic development scenarios we analyse these targets from two perspectives consistency with the overall economic growth and consistency with the international society s expectation on china s greenhouse gas ghg abatement responsibilities the main findings are under the recently announced 2020 target of gross domestic product gdp that is double the 2010 level the adoption of a 15 clean energy target could result in excessive primary energy demand and then with 40 45 gdp co2 intensity reduction co2 emissions in 2020 could substantially exceed the international energy agency iea 450 ppm scenario for china thus we propose a 17 clean energy target that can reconcile the domestic plan with international expectation our article also outlines the pathways to realise clean energy development into 2020 and proposes policy recommendations

spatial differentiation and vertical mergers in retail markets for gasoline this paper studies an empirical model of spatial competition applied to gasoline markets the main feature is to specify commuting paths as the locations of consumers in a hotelling style model as a result spatial differentiation depends in an intuitive way on the structure of the road network and the direction of traffic flows the model is estimated using panel data on the quebec city gasoline market and used to evaluate the consequences of a recent vertical merger difference in difference and counterfactual simulation methods are compared and the results to a large extent validate the assumptions of the demand model jel g34 l13 l42 l81 q41 r41

carbon intensity changes in the asian dragons lessons for climate policy design abstract there is a growing political interest in carbon intensity targets because they are the basis for climate pledges from relevant developing countries such as china they may be also the basis for policy designs in developed countries like eu members this paper develops a comprehensive econometric study on the main drivers of national emissions intensity in emerging countries in east asia this regional focus responds to their pivotal position in global economic growth and remarkable trends in carbon emissions intensity the main hypothesis of this paper is that the nature of economic growth has a major effect on carbon intensity trends that deserves some attention accordingly the novelty of this paper is to examine the contribution of intensive and extensive gdp growth for carbon intensity abatements labour productivity is revealed to be the main factor responsible for major carbon intensity reductions by asian dragons whereas household energy per capita and industrial energy per worker contributed in the opposite direction consequently intensity targets may become meaningless for real climate action contributions if they do not take into account labour productivity trends

how ambitious are china and india s emissions intensity targets abstract several developing economies have announced carbon emissions targets for 2020 as part of the negotiating process for a post kyoto climate policy regime china and india s commitments are framed as reductions in the emissions intensity of the economy by 40 45 and 20 25 respectively between 2005 and 2020 how feasible are the proposed reductions in emissions intensity for china and india and how do they compare with the targeted reductions in the us and the eu in this paper we use a stochastic frontier model of energy intensity to decompose energy intensity into the effects of input and output mix climate and a residual technology variable we use the model to produce emissions projections for china and india under a number of scenarios regarding the pace of technological change and changes in the share of non fossil energy we find that china is likely to need to adopt ambitious carbon mitigation policies in order to achieve its stated target and that its targeted reductions in emissions intensity are on par with those implicit in the us and eu targets india s target is less ambitious and might be met with only limited or even no dedicated mitigation policies

can china achieve its carbon intensity target by 2020 while sustaining economic growth in 2009 the chinese government announced its carbon intensity target for 2020 can china achieve this carbon intensity while sustaining economic growth to address this essential issue the contributions of this study lie in three aspects first we quantitatively capture the relationship between china s economic growth and energy consumption using the cointegration theory and predict china s energy consumption by 2020 according to different economic growth targets second we forecast china s energy structure in 2020 using compositional data and arima models under different scenarios third we deduce china s co2 emission and carbon intensity in 2020 furthermore we investigate whether or not china can realize the carbon intensity target in premise of ensuring economic growth and evaluate the contribution of the energy structure s adjustment to meeting this target finally we put forward some relevant policy implications for achieving china s carbon intensity target

who moves a logit model analysis of inter provincial migration in canada this paper addresses the topic of inter provincial migration in terms of the basic question who moves panel logit models of the probability that an individual changes his or her province of residence from one year to the next over the 1982 1995 period are estimated using tax based longitudinal data it is found that moving is i inversely related to the home province s population size presumably reflecting local economic conditions and labour market scale effects while language also plays an important role ii more common among residents of smaller cities towns and especially rural areas than those in larger cities iii negatively related to age marriage and the presence of children for both men and women iv positively related to the provincial unemployment rate the individuals receipt of unemployment insurance except entry men having no market income except for entry men and entry women and the receipt of social assistance especially for men v slightly positively related

applied welfare economics with discrete choice models economists have been paying increasing attention to the study of situations in which consumers face a discrete rather than a continuous set of choices such models are potentially very important in evaluating the impact of government programs upon consumer welfare but very little has been said in general regarding the tools of applied welfare economics indiscrete choice situations this paper shows how the conventional methods of applied welfare economics can be modified to handle such cases it focuses on the computation of the excess burden of taxation and the evaluation of quality change the results are applied to stochastic utility models including the popular cases of probit and logit analysis throughout the emphasis is on providing rigorous guidelines for carrying out applied work this abstract was borrowed from another version of this item

revealing the political decision toward chinese carbon abatement based on equity and efficiency criteria abstract china s economic reform over the past 30 years has allowed the free market to drive economic development however government still plays a key role in the energy sector by allocating energy conservation and emissions abatement how does the government make an equity decision as a tradeoff to market efficiency this is an unanswered question the purpose of this paper is to illustrate the government s preference toward equity and efficiency using the provincial level co 2 intensity allocation data we investigate the political decision that the government made based on the equity and efficiency criteria we find that the equity index plays a more important role than the efficiency index in determining the co 2 intensity target in addition political factors such as social stability are found to be important factors

mergers with differentiated products the case of the ready to eat cereal industry traditional merger analysis is difficult to implement when evaluating mergers in industries with differentiated products i discuss an alternative which consists of demand estimation and the use of a model of postmerger conduct to simulate the competitive effects of a merger i estimate a brand level demand system for ready to eat cereal using supermarket scanner data and use the estimates to 1 recover marginal costs 2 simulate postmerger price equilibria and 3 compute welfare effects under a variety of assumptions the methodology is applied to five mergers two of which occurred and for which i compare predicted to actual outcomes

characteristics of demand for pharmaceutical products an examination of four cephalosporins we model demand for four cephalosporins and compute own and cross price elasticities between branded and generic versions of the four drugs we model demand as a multistage budgeting problem and we argue that such a model is appropriate to the multistage nature of the purchase of pharmaceutical products in particular the prescribing and dispensing stages we find quite high elasticities between generic substitutes and also significant elasticities between some therapeutic substitutes

technological change technological catch up and capital deepening relative contributions to growth and convergence we decompose labor productivity growth into components attributable to 1 technological change shifts in the world production frontier 2 technological catch up movements toward or away from the frontier and 3 capital accumulation movement along the frontier the world production frontier is constructed using deterministic methods requiring no specification of functional form for the technology nor any assumption about market structure or the absence of market imperfections we analyze the evolution of the cross country distribution of labor productivity in terms of the tripartite decomposition finding that technological change is decidedly nonneutral and that both growth and bipolar international divergence are driven primarily by capital deepening jel o30 o47 d24

cost pass through in differentiated product markets the case of u s processed cheese in this paper we estimate a mixed logit model for demand in the u s processed cheese market the estimates are used to determine pass through rates of cost changes under different behavioral regimes we find that under collusion the pass through rates for all brands fall between 21 and 31 while under nash bertrand price competition the range of pass through rates is between 73 and 103 the mixed logit model provides a more flexible framework for studying pass through rates than the logit model since the curvature of the demand functions depends upon the empirical distribution of consumer types

airline code share alliances and their competitive effects abstract code share alliances have become a prominent feature in the competitive landscape of the airline industry however policy makers are extremely hesitant to approve proposed code share alliances when the potential partners route networks have significant overlap the main concern is that an alliance may facilitate price collusion on partners overlapping routes this article shows how policy makers can use a structural econometric framework to quantify the competitive effects of proposed code share alliances where potential alliance partners compete on overlapping routes in the prealliance industry as an example i apply the econometric model to the delta continental northwest alliance this proposed alliance was initially greeted with skepticism by the u s department of transportation owing to the potential partners unprecedented level of route network overlap for the markets considered in my analyses it appears as though the ultimate approval of the alliance by policy makers was justified

the gains from merger or collusion in product differentiated industries a merger in an industry with differentiated products increases the market power of the merging firms to the extent that their products are close substitutes and that other firms produce only more distant substitutes such a merger makes the residual demand curve of each partner steeper by shifting each in the direction of the industry demand curve 2 the extent of this increase in market power depends upon the own elasticity of demand for each merging firm s product as well as the cross elasticity of demand for each with all other firms products as a result evaluating the effect of a merger between two firms with n 2 other competitors would seem to require the estimation of at least n2 parameters all of the price elasticities of demand a formidable task that extremely difficult estimation task is unnecessary however the necessary information is contained in the slopes of the two single firm residual demand curves before the merger and the extent to which the merged firm will face a steeper demand curve for example suppose a merger between two u s brewing firms say pabst and anheuser busch were proposed it is not particularly important to determine whether it is competition from miller or competition from stroh or from heileman or which puts the most effective brake on anheuser busch s pricing only the total effect of these other firms and the particular effect of competition from pabst are of interest this paper proposes econometric procedures for estimating the demand system that merger partners will face based only on pre merger data the key to the procedures is that the effects of all other firms in the industry are summed together formally we start with a model of an n firm product differentiated industry manipulation of the model removes the prices and quantities of all but two firms this reduces the dimensionality of the problem to manageable size rather than an n firm demand system we estimate a two firm residual demand system in this way the technique extends our econometric method for

co2 emissions and economic activity short and long run economic determinants of scale energy intensity and carbon intensity we analyze the short term and the long term determinants of energy intensity carbon intensity and scale effects for eight developed economies and two emerging economies from 1973 to 2007 our results show that there is a difference between the short term and the long term results and that climate policy are more likely to affect emission over the long term than over the short term climate policies should therefore be aimed at a time horizon of at least 8 years and year on year changes in emissions contains little information about the trend path of emissions in the long run capital accumulation is the main driver of emissions productivity growth reduces the energy intensity while the real oil price reduces both the energy intensity and the carbon intensity the real oil price effect suggests that a global carbon tax is an important policy tool to reduce emissions but our results also suggest that a carbon tax is likely to be insufficient decouple emission from economic growth such a decoupling is likely to require a structural transformation of the economy the key policy challenge is thus to build new economic structures where investments in green technologies are more profitable

changes in energy efficiency in australia a decomposition of aggregate energy intensity using logarithmic mean divisia approach abstract this paper provides an empirical estimation of energy efficiency and other proximate factors that explain energy intensity in australia for the period 1978 2009 the analysis is performed by decomposing the changes in energy intensity by means of energy efficiency fuel mix and structural changes using sectoral and sub sectoral levels of data the results show that the driving forces behind the decrease in energy intensity in australia are efficiency effect and sectoral composition effect where the former is found to be more prominent than the latter moreover the favourable impact of the composition effect has slowed consistently in recent years a perfect positive association characterizes the relationship between energy intensity and carbon intensity in australia the decomposition results indicate that australia needs to improve energy efficiency further to reduce energy intensity and carbon emissions

emissions in the platinum age the implications of rapid development for climate change mitigation rapid global economic growth centred in asia but now spread across the world is driving rapid greenhouse gas emissions growth making earlier projections unrealistic this paper develops new illustrative business as usual projections for carbon dioxide co2 from fossil fuels and other sources and for non co2 greenhouse gases making adjustments to 2007 world energy outlook projections to reflect more fully recent trends we project annual emissions by 2030 to be almost double current volumes 11 per cent higher than in the most pessimistic scenario developed by the intergovernmental panel on climate change ipcc and at a level reached only in 2050 in the business as usual scenario used by the stern review this has major implications for the global approach to climate change mitigation the required effort is much larger than implicit in the ipcc data informing the current international climate negotiations large cuts in developed country emissions will be required and significant deviations from baselines will be required in developing countries by 2020 it is hard to see how the required cuts could be achieved without all major developing as well as developed countries adopting economy wide policies

estimating multiple discrete choice models an application to computerization returns buyers in many markets face multiple discrete choices they can purchase multiple units as well as multiple brands at the same time this paper presents a multiple discrete choice model for the analysis of differentiated products demand users maximize profits by choosing the number of units of each brand they purchase i estimate the model using micro level data on the demand for personal computers i use the estimated demand structure to assess the welfare gains from computerization and technological innovation in peripherals the estimated return on investment in personal computers is 92 moreover a 10 increase in the performance to price ratio of microprocessors leads to a 2 2 gain in the estimated user surplus the personal computer pc market is of interest to industrial organization economists because of its size the continual technological change and above all because of the farreaching implications of pcs on the economy as a whole several distinct features make pc demand difficult to model pcs are a differentiated durable good in constant technological evolution moreover buyers make multiple discrete choices firms according to our data spread their purchases of pcs over different brands at the same time they buy pcs in blocks several units of each brand that they have chosen the aim of the paper is to present a model that captures these features and to use this model to estimate the welfare gains from computerization classical discrete choice models allow one choice among mutually exclusive alternatives in contrast the proposed framework allows users to demand multiple units and multiple brands the model can be applied to other cases of multiple discrete choices e g the composition of airline fleets car holdings per household the fields of the faculty in economics departments household cereals consumption or any other good consumed in more than one variety during a relevant time period although pervasive multiple discrete choice problems have received little attention because of their complexity a central issue regarding the pc market is the current controversy in the economics literature about the computerization puzzle this puzzle stems from the empirical finding that computerization has had no effect on firm productivity griliches and siegel 1991 and morrison and berndt 1990 contrary to those results hendel 1994 and lichtenberg 1995 using more disaggregate data than most previous studies report excess returns to computerization this indicates that data aggregation may have created the computerization puzzle in this paper i present a model consistent with the basic

choice inconsistencies among the elderly evidence from plan choice in the medicare part d program comment consumers enrollment decisions in medicare part d can be explained by abaluck and gruber s 2011 model of utility maximization with psychological biases or by a neoclassical version of their model that precludes such biases we evaluate these competing hypotheses by applying nonparametric tests of utility maximization and model validation tests to administrative data we find that 79 percent of enrollment decisions from 2006 to 2010 satisfied basic axioms of consumer theory under the assumption of full information the validation tests provide evidence against widespread psychological biases in particular we find that precluding psychological biases improves the structural model s out of sample predictions for consumer behavior

a generalized production frontier approach for estimating determinants of inefficiency in u s dairy farms this article investigates farm level efficiency of u s dairy farmers by estimating their technical and allocative efficiency technical inefficiency is assumed to be composed of a deterministic component that is a function of some farm specific characteristics and a random component by doing this we extend the stochastic frontier methodology in which determinants of technicial inefficiency are explicitly introduced in the model given the inputs variations in efficiency of farms are then explained by both deterministic and random components of technical inefficiency the empirical results indicate that a levels of education of the farmer are important factors determining technical inefficiency and b large farms are more efficient technically than small and medium sized farms both technical and allocative inefficiency are found to decrease with increase in the level of education of the farmer

choice set heterogeneity and the role of advertising an analysis with micro and macro data abstract the authors show how to use microlevel survey data from a tracking study on brand awareness in conjunction with data on sales and advertising expenditures to improve the specification estimation and interpretation of aggregate discrete choice models of demand in a departure from the commonly made full information assumption they incorporate limited information in the form of choice sets to reflect that consumers may not be aware of all available brands at purchase time they find that both the estimated brand constants and the price coefficient are biased downward when consumer heterogeneity in choice sets is ignored these biased estimates can lead firms to make costly price setting mistakes in addition the tracking data enable the authors to identify separately two processes by which advertising influences market shares they find that advertising has a direct effect on brand awareness inclusion in choice set in addition to its effect on consumer preferences increase in utility this

china s strategy for carbon intensity mitigation pledge for 2020 evidence from a threshold cointegration model combined with monte carlo simulation methods abstract this paper specifies a nonlinear threshold cointegration to analyze the nonlinear relationship between carbon intensity and economic growth in china the tests and estimated results clearly confirm that fast paced economic growth that is the growth rate of gross domestic product gdp is greater than 9 053 impede the reduction of carbon intensity because it weakens the negative effects of tertiary industry development and energy efficiency on carbon intensity while it also increases the positive effect of unclean energy mix on carbon intensity in order to find a moderate range of economic growth rate that is both beneficial for industrial structuring and energy mix transformation and at the same time facilitate reduction in carbon intensity monte carlo simulations are employed the results show when the growth rate of gdp is between 7 and 8 4 it can promote structural bonus of industrial structure and energy consumption structure on carbon intensity and carbon intensity in 2020 would decline by about 40 60 compared to 2005 level these conclusions mean it is necessary for china to carefully set its economic growth target through transformation and optimization of its economic structure and energy mix in order to continuously reduce carbon intensity

a critical overview of industrial energy decoupling programs in six developing countries in asia in reviewing the journal literature on the decoupling of energy use and industrial output in the asian region particularly with respect to developing countries we found little information about most country programs other than for china and india and only one article that compared the programs of these two countries for this reason we used diverse sources to identify the key programmatic features that have contributed but clearly are not totally responsible for decoupling achievements of two countries china and thailand and then on the basis of these findings reviewed emerging industrial energy decoupling programs in four other countries india indonesia malaysia and vietnam we found that the design of the two successful on going decoupling programs have common features which are setting an explicit target for decoupling of energy use and industrial output a government program that offers financial incentives and imposes specific auditing and reporting requirements and involvement of the manufacturing sector in designing and implementing targets as they apply to individual enterprises we also found that the emerging programs in the other four countries lack some or all of these essential programmatic features

interregional migration and interindustry labour mobility in canada a simultaneous approach this paper argues that interindustry labour mobility and interregional migration are simultaneously determined processes it estimates a bivariate probit model of migration and mobility using data for canada and concludes that the interindustry mobility of labour is dominated by the availability of employment hours and that wage differentials are a statistically significant but small determinant of interregional migration since interindustry mobility is much larger in magnitude than interregional migration quantity constraints in labour markets are of central importance to the adaptive capacity of the economy summary in fre excerpt

labor supply preferences hours constraints and hours wage tradeoffs in a labor market with tied hours wage packages and wage dispersion for a particular type of job constrained workers may be willing to sacrifice wage gains for better hours when changing jobs likewise workers may accept jobs offering undesirable hours only if the associated wage gains are large we investigate this issue empirically by examining whether overemployment and underemployment on the initial and new job affects the relation between hours changes and wage changes for quitters our results generally support the view that an individual requires compensation to work in a job that given the individual s particular preferences offers unattractive hours

the response of latino immigrants to the great recession occupational and residential im mobility during the great recession in the us there were distinct housing and labour markets that were particularly hard hit this was primarily due to the fact that the housing industry had fueled much of the recent economic growth this article takes advantage of the shock to the construction industry to investigate the responses of latino immigrants in metropolitan areas that were most heavily concentrated with latino immigrants in the construction industry as expected there were large declines in the proportion of the latino immigrant population that was working in the construction industry during the recession there were some shifts of employment in the industry after the recession but the biggest change was in the number of unemployed while declines in construction jobs did predict moving out of a metropolitan area decline in the overall job market had a larger impact on mobility finally we find evidence that those who moved out of the metropolitan area were less likely to be employed although it i

corruption pollution and the kuznets environment curve abstract this paper examines the implications of corruption and rent seeking behavior by the government for the relationship between pollution and growth cases of both cooperative and non cooperative interaction between the government and the private firm are studied it is shown that corruption is not likely to preclude the existence of an inverted u shaped kuznets environmental curve under both these cases however for any level of per capita income the pollution levels corresponding to corrupt behavior are always above the socially optimal level further the turning point of the kuznets curve takes place at income and pollution levels above those corresponding to the social optimum

how can chile move away from a high carbon economy abstract this paper quantitatively evaluates the performance of chile s co2 emissions between 1991 and 2013 using a complete decomposition technique to examine emissions and their components a decomposition analysis based on log mean divisia index method lmdi i was conducted six decomposition factors were considered carbon intensity effect ci res penetration effect res energy intensity effect ei economy structure effect es income effect yp and population effect p to know how these factors could influence each other in the future the innovative accounting approach iaa was used including forecast error variance decomposition and impulse response functions irfs these two methodologies allow us to identify the drivers of co2 emission changes in the past 1991 2013 test policy measures and learn how these drivers could influence each other in the future to evaluate whether the current measures meet the paris commitments the lmdi analysis results show that the energy intensity factor is the main compensating factor of chile s co2 emissions and the only effect with a clear trend to aid the economy s decoupling iaa and ifrs results react similarly and confirm that carbon intensity reacts to shocks more significantly in the short term the reaction to res has the same and opposite behavior to shocks in es and yp to disappear in the long term
