are environmental taxes a free lunch issues in modelling the macroeconomic effects of carbon taxes applied analysis of output and employment effects from revenue neutral environmental taxation depends critically on how the supply side of the economy is modelled despite the long history of theoretical and computable general equilibrium supply side models the empirical basis of much of this work has been quite weak until recently however most econometric attempts to capture factor substitution effects have not been based on theoretically consistent structures this paper examines the methodological issues that underlie these problems and compares the results of imposing environmental taxes in two different econometric modelling structures the implications of theories of endogenous technical progress on the simulation properties of such models are discussed and a simple empirically based model that embodies some of these features is presented

robust tests for unit roots in the foreign exchange market abstract empirical studies that have tested for unit roots in foreign exchange rate data have assumed independent and identically distributed errors in order to apply dickey fuller test procedures this assumption ignores the temporal dependence of the error sequence present in many simple efficient market tests as discussed in hansen and hodrick 1980 as well as krasker 1980 in this paper we apply unit root test statistics that allow for heterogeneously distributed and mildly dependent error processes and thus provide superior tests of the unit root hypothesis in the case of foreign exchange rates

the labour market participation of northern ireland university students this paper seeks to examine what factors are associated with student labour force participation in northern ireland in both term time and vacation making use of quarterly labour force survey data for the period march 1998 february 1999 the results suggest female students are more likely to work than male students mature students are less likely to work than non mature students roman catholic students are less likely to work than non roman catholic students students living at home are more likely to work than student living away from home and an increase in the actual or predicted wage increases the probability of labour force participation the author suggests that some of these results are due to the particular nature of the northern ireland socio economic situation while others are likely to be true for the rest of the united kingdom

a cointegration analysis of petroleum futures prices abstract this paper presents evidence concerning the number of common stochastic trends in a system of three petroleum futures prices crude oil heating oil and unleaded gasoline using daily data from 3 december 1984 to 30 april 1993 johansen s maximum likelihood approach for estimating long run relations in multivariate vector autoregressive models is used the results indicate the presence of only one common trend

estimating elasticities of substitution with nested ces production functions where do we stand abstract prompt by an increasing interest by climate change modelers a rich literature estimating elasticities of substitution in a nested ces production framework has recently developed this article reviews such literature we critically describe the nesting structures estimation approaches data sources and aggregation econometric techniques and types of substitution elasticities used by previous literature to offer a comprehensive description of the various options available to a researcher attempting this estimation we also provide suggestions for potential improvements to the estimation process in particular we warn researchers to use ces production functions with caution in empirical applications given their restrictive build in assumptions

refining for export and the convergence of petroleum product prices abstract the petroleum refining industry has changed over the past decades from one in which capacity primarily served local and regional markets to one in which trade in refined petroleum products has become more widespread we investigate the hypothesis of increasing globalization by examining the convergence of prices for refined products across different markets using data on refined products from market centers in the us and europe we test for convergence of prices using standard time series techniques the data plainly show that markets for refined petroleum products have become more interrelated as europe exported its gasoline surplus and global demand for petroleum products approached refining capacity econometric evidence supports the hypothesis that the us and european markets for oil and refined products are integrated we find evidence that a structural break during the financial crisis of 2008 changed the long run equilibrium price relationships and the short run price dynamics refined product markets are likely to experience continued globalization given trends in the united states and europe and because of key export oriented refining capacity investments made to take advantage of access to specific crude oil sources

toward the integration of european natural gas markets a time varying approach abstract over the past fifteen years european gas markets have radically changed in order to build a single european gas market a new regulatory framework has been established through three european gas directives the purpose of this article is to investigate the impact of the reforms in the natural gas industry on consumer prices with a specific focus on gas prices for industrial use the strength of the relationship between the industrial gas prices of six western european countries is studied by testing the law of one price for the period 1991 2009 estimations were carried out using both cointegration analysis and time varying parameter models results highlight an emerging and on going process of convergence between the industrial gas prices in western europe since 2001 for the six eu member states the strength and the level of convergence differ widely between countries strong integration of gas markets in continental europe except for the belgian market has been established it appears that the convergence process between continental countries and the uk is not completed thus the integration of european gas markets remains an open issue and the question of how far integration will proceed will still be widely discussed in the coming years

demand for football and intramatch winning probability an essay on the glorious uncertainty of sports the aims of this study are i to identify the main determinants of the demand for french premiere division football matches using all matches played during the 1997 1998 season ii to estimate a team specific probability of success and iii to propose an updating process for the intramatch winning probability the methodology is tested empirically over an out of sample data set using matches of the 1998 1999 season the results show that football appears to be an inferior product affected by both socio economic and football variables and that the main football variables have only a tenuous explanatory power concerning the final outcome of a given match

testing for common features in north american energy markets abstract using recent advances in the field of applied econometrics we explore the strength of shared trends and shared cycles between north american natural gas and crude oil markets in doing so we use daily data from january 1991 to april 2001 on spot u s henry hub natural gas and wti crude oil prices the results show that there has been decoupling of the prices of these two sources of energy as a result of oil and gas deregulation in the united states we also investigate the interconnectedness of north american natural gas markets and find that north american natural gas prices are largely defined by the u s henry hub price trends

participation in school sponsored sports and academic spillovers new evidence from the early childhood longitudinal survey the link between participation in school sponsored sports and academic performance has been studied extensively in the literature whilst previous studies tend to show positive academic spillovers

modeling and forecasting cointegrated relationships among heavy oil and product prices abstract in this paper we investigate heavy crude oil and product price dynamics we present a comparison among ten prices series of heavy crude oils and fourteen price series of petroleum products in two distinct areas europe and americas over the period 1994 2002 we provide a complete analysis of crude oil and product price dynamics using cointegration and error correction models ecm subsequently we use the ecm specification to predict crude oil prices over the horizon january 2002 june 2002 finally we compare the forecasting performance of ecm with a naive model in first differences which does not exploit any cointegrating relation

demand for sport this article reviews international literature on the demand for professional sport the first part presents a conceptual framework for understanding the sources and determinants of the demand for professional sporting contests the second part reviews empirical evidence on key determinants of attendance at sporting events and on other sources of demand such as broadcasting sponsorship and merchandising the review concludes that there is still much to be learned about demand for professional sport and that there are no simple lessons to be drawn from existing literature but important messages do emerge from studies of demand for attendance with regard to effects of uncertainty of outcome quality of contest and quality of viewing copyright 2003 oxford university press

student participation in sporting activities given that many universities spend large sum of money supplying sports facilities for student use comparatively little is known about the factors that influence the quantity of student sporting participation this article presents evidence which suggests that the quantity of student sports participation is negatively related to the number of hours they work while augmenting social capital and sports literacy are found to enhance their sports participation universities need to target their investment in sporting facilities to meet students demands and not simply to increase the range of sports facilities available to students

input substitution effect in china s chemical industry evidences and policy implications abstract the chemical industry is one of the six high energy consuming and emission intensive sectors in china and the chinese government has focused its attention on energy saving and emissions reduction in the sector with the aim of contributing to the objective of energy saving and emission reduction in the sector this article studies the external substitution relationship of capital energy and labor energy using the translog production function and ridge regression the results are as follow the output elasticities of energy labor and capital are positive the substitution elasticities of capital labor capital energy and labor energy are positive and stable and their values are close to 1 which indicates that the three factors are substitutes for one another furthermore based on the above function we measure the level of energy saving and emissions reduction under different scenarios in 2012 policy implications of the results are provided

crack spread hedging accounting for time varying volatility spillovers in the energy futures markets crude oil heating oil and unleaded gasoline futures contracts are simultaneously analysed for their effectiveness in reducing price volatility for an energy trader a conceptual model is developed for a trader hedging the crack spread various hedge ratio estimation techniques are compared to a multivariate garch model that directly incorporates the time to maturity effect often found in futures markets modelling of the time variation in hedge ratios via the multivariate garch methodology and thus taking into account volatility spillovers between markets is shown to result in significant reductions in uncertainty even while accounting for trading costs copyright 2002 john wiley sons ltd

the macroeconomy of angola breaks and persistence in angolan macro data using long range dependence techniques we examine the order of integration of angola s macro variables from a fractional viewpoint based on a small open economy model the series examined are money reserves credit money supply lending rate exchange rates cpi gdp oil revenues and government expenditure for the period of january 2000 to december 2013 the results suggest that the variables are nonstationary with orders of integration equal to or higher than 1 suggesting nonmean reverting behaviour structural breaks reveal that the series reflect the imf intervention in angola in 2003 to control inflation policy implications are derived

price discovery in energy markets abstract in this study we empirically analyze the price discovery process in the futures and spot markets for crude oil heating oil and natural gas using daily closing prices we use two different information share measures that are based on the methods proposed by gonzalo and granger 1995 and lien and shrestha 2014 both measures indicate that almost all the price discovery takes place in the futures markets for the heating oil and natural gas however for the crude oil the price discovery takes place both in the futures and spot markets as a whole our study indicates that futures markets play an important role in the price discovery process

convergence to the long run equilibrium the case of natural gas markets abstract intuitively the persistence of a shock may last longer in futures contracts with a longer maturity estimation of the speed with which different contract lengths converges to the long run equilibrium following a shock provides a means for comparing the informational efficiency of the contracts standard empirical investigation of the response of a market to a shock utilizes impulse response analysis however this analysis is problematic since there is not a unique variance covariance decomposition pesaran and shin pesaran m h shin y 1996 cointegration and speed of convergence to equilibrium j econ 71 117 143 introduced an alternative to the standard impulse response analysis the persistence profile by estimating the one step ahead forecast error for the entire system the persistence profile provides a unique measure of the effect of the shock this paper empirically estimates persistence profiles for the natural gas futures market the findings indicate that the persistence of a shock does increase with the contract length

analysing the technical efficiency of the spanish football league first division with a random frontier model this article analyses technical efficiency of football clubs in the spanish football league division 1 primera liga from the seasons 1995 1996 to 2004 2005 with an unbalanced panel data the random frontier model is used allowing the identification of random variables in the cost frontier it is concluded that the price of capital investment the number of points won and attendance are heterogeneous variables therefore no common public policy aiming to improve efficiency can embrace all of the clubs so that policies by clusters are required

factor substitution in u s manufacturing does plant size matter we use micro data for 10 412 u s manufacturing plants to estimate the degrees of factor substitution by industry and by plant size we find that 1 capital labor energy and materials are substitutes in production and 2 the degrees of substitution among inputs are quite similar across plant sizes in a majority of industries two important implications of these findings are that 1 small plants are typically as flexible as large plants in factor substitution consequently economic policies such energy conservation policies that result in rising energy prices would not cause negative effects on either large or small u s manufacturing plants and 2 since energy and capital are found to be substitutes the 1973 energy crisis is unlikely to be a significant factor contributing to the post 1973 productivity slowdown

a bayesian stochastic frontier of italian football this study analyses the technical efficiency of serie a italian football clubs during the 2004 2012 seasons with a bayesian stochastic frontier model using unique data extracted from clubs annual reports specifically the focus of the study is on assessing the impact effects on clubs efficiency whether they are big clubs they employ several foreign player they compete in european competitions and their involvement with football scandals in the italian football the empirical results reveal that efficiency varies among the clubs analysed and policy implications are derived

common stochastic trends in a system of exchange rates univariate tests reveal strong evidence for the presence of a unit root in the univariate time series representation for seven daily spot and forward exchange rate series furthermore all seven spot and forward rates appear to be cointegrated that is the forward premiums are stationary and one common unit root or stochastic trend is detectable in the multivariate time series models for the seven spot and forward rates respectively this is consistent with the hypothesis that the seven exchange rates possess one longrun relationship and that the disequilibrium error around that relationship partly accounts for subsequent movements in the exchange rates a general consensus has emerged in recent years that many macroeconomic time series such as gnp consumption expenditures disposable income etc can be characterized by a stochastic trend model in particular nelson and plosser 22 described this property as one of being difference stationary so that the first difference of a time series is stationary an alternative trend stationary model where a stationary component is added to a deterministic trend term has generally been found to be less appropriate 1 similarly it has long been recognized that many financial time series such as foreign exchange rates are nonstationary e g in meese and singleton 21 the issue of nonstationary is not merely a statistical curiosity but has several important implications for the modeling of exchange rates for instance many models of exchange rate determination under rational expectations require stationarity assumptions when solving out the expected future values of the fundamentals further there has been some controversy over the appropriate transformations to use when conducting tests of whether the forward rate is an unbiased and efficient predictor of the future spot exchange rate 2 some authors e g frenkel 11 12 have conducted tests in levels while geweke and feige 14

the demand for semi pro league football in malaysia 1989 91 a panel data approach this article arguments the literature on the demand for professional team sports by estimating a demand function for attendance at home matches in the malaysian semi pro football league mspfl between 1989 and 1991 a single equation demand attendance function based on a pooled cross section and time series panel data set of 399 games is estimated by ordinary least squares a fixed effects dummy variable covariance model and an error components model our findings confirm the importance of market size and championship prospects for the home team but not the visiting team as well as divisional status and star players the first match of the season and derby matches also increased attendance

cost efficiency of french rugby clubs this article analyses the cost efficiency of french first league rugby clubs using a stochastic frontier model the frontier estimation confirmed that the model fits the data well with all coefficients correctly signed and in line with the theoretical requirements the results show that one of the clubs is operating efficiently with the majority of clubs clustered around 20 inefficiency policy implications are derived

our fans in the north the demand for british rugby league this paper reports the results of estimating a single equation model of an attendance function for british rugby league over the seasons 1982 83 to 1990 91 the data are panel data covering virtually every team which played in the two division league over the nine year time period diagnostic tests indicate that the appropriate model is a semilog random effects model where the dependent variable is league attendance weighted by population the major results are as follows there are significant positive relationships between league attendance and various measures of team success although the direction of causality is moot team quality as proxied by the two divisions and the economic quality of team location as proxied by the unemployment rate but there is no discernible relationship between league attendance and either success in nonleague trophy competitions or measures of exceptional player quality

the demand for league football a demand equation is estimated for total football league attendances for the period 1948 49 to 1979 80 plausible values are obtained for the elasticities of demand with respect to income and to a price variable which includes the cost of travel to the stadium the values imply that football spectating is an inferior good with a low price elasticity equations are also estimated for the league s separate divisions the implications of the results for the football league clubs are discussed

trends and cycles in macroeconomic time series two structural time series models for annual observations are constructed in terms of trend cycle and irregular components the models are then estimated via the kalman filter using data on five u s macroeconomic time series the results provide some interesting insights into the dynamic structure of the series particularly with respect to cyclical behavior at the same time they illustrate the development of a model selection strategy for structural time series models

price discovery in oil markets a time varying analysis of the 1990 1991 gulf conflict abstract this study examines the behaviour of crude oil spot and futures markets in the uk and usa during the 1990 1991 gulf conflict the objective is to investigate the relative ability of spot and futures markets to impound information this is achieved with the use of a generalized model of price discovery which represents a synthesis of the two most commonly used methodologies in its field emphasis is placed on the time varying nature of price discovery relationships results indicate that such relationships are strongly temporal these findings offer new insights into the nature of relationships between spot and futures markets

have oil and gas prices got separated abstract this paper applies vector error correction models that show that oil and natural gas prices decoupled around 2009 before 2009 us and uk gas prices had a long term equilibrium with crude prices to which gas prices always reverted after exogenous shocks both us and uk gas prices adjusted to the crude oil price individually and departure from the equilibrium gas price on one continent resulted in a similar departure on the other after an exogenous shock the adjustment between us and uk gas prices took approximately 20 weeks on average and the convergence was mediated mainly by crude oil with a necessary condition that arbitrage across the atlantic was possible after 2009 however the uk gas price has remained integrated with oil price but the us gas price decoupled from crude oil price and the european gas price as the atlantic arbitrage has halted the oversupply from shale gas production has not been mitigated by north american export as there has been no liquefying and export capacity

gradual reforms and the emergence of energy market in china evidence from tests for convergence of energy prices this study investigates the emergence of energy markets by testing for convergence of energy prices with a new dataset on energy spot prices in 35 major cities in china both descriptive statistics and unit root are employed to test the convergence of energy prices for each of four fuel price series the whole study period is divided into two sub periods in order to reconcile the gradual energy reforms the results show the steady improvement in energy market performance in china especially during the second sub period which suggests that the market appears to be playing an increasing role in determining energy prices while panel unit root tests show energy markets are integrated in china as a whole city by city univariate unit root tests suggest that there are still many regional energy markets probably because energy reserves especially coal vary widely across regions since china s energy economy is gradually moving towards market oriented mechanisms the existing literature may become obsolete soon

the brazilian soccer championship an efficiency analysis this article analyses the top brazilian football league from 2003 to 2011 by estimating a cost function and using a stochastic frontier model among the covariates the number of fans per club and club remoteness is taken into account the brazilian clubs are then ranked according to their technical efficiency during the 2000 2011 period based on the results the policy implication is presented and the economic implications arising from the study are also considered

the own wage elasticity of labor demand a meta regression analysis firms labor demand responses to wage changes are of key interest in empirical research and policy analysis however despite extensive research estimates of labor demand elasticities remain subject to considerable heterogeneity in this paper we conduct a comprehensive meta regression analysis to re assess the empirical literature on labor demand elasticities building on 942 elasticity estimates from 105 different studies we identify sources of variation in the absolute value of this elasticity heterogeneity due to the theoretical and empirical specification of the labor demand model different datasets used or sectors and countries considered explains more than 80 of the variation in the estimates we further find substantial evidence for the presence of publication selection bias as estimates of the own wage elasticity of labor demand are upwardly inflated

mean variance asset liability management cointegrated assets and insurance liability abstract the cointegration of major financial markets around the globe is well evidenced with strong empirical support this paper considers the continuous time mean variance mv asset liability management alm problem for an insurer investing in an incomplete financial market with cointegrated assets the number of trading assets is allowed to be less than the number of brownian motions spanning the market the insurer also faces the risk of paying uncertain insurance claims during the investment period we assume that the cointegration market follows the diffusion limit of the error correction model for cointegrated time series using the markowitz 1952 mv portfolio criterion we consider the insurer s problem of minimizing variance in the terminal wealth given an expected terminal wealth subject to interim random liability payments following a compound poisson process we generalize the technique developed by lim 2005 to tackle this problem the particular structure of cointegration enables us to solve the alm problem completely in the sense that the solutions of the continuous time portfolio policy and efficient frontier are obtained as explicit and closed form formulas

electricity demand of manufacturing sector in turkey a translog cost approach abstract this paper models factor demand for manufacturing sector in turkey we estimated a translog cost function with four factor consist of capital labor intermediate input and electricity over the 1980 2001 our objective taking in the consideration electricity as production input was twofold on the one hand to estimate the price elasticity of electricity demand in manufacturing sector and on the other hand to use cross price and morishima elasticities of substitution results for structural analysis regarding effects of electricity liberalization which initiated in 2001 empirical result shows that electricity demand is relatively price sensitive 0 85 our result in terms of electricity price is consistent with the previous studies while electricity labor and electricity capital inputs are complementary results indicate the existence of substitution possibilities between electricity and intermediate input this means that changes in electricity prices have impact on labor demand and investment demand these results have important implications for public policy

does european regional competitiveness influence sports an analysis of three sports the main objective of this work was to test european regional determinants of sports competitiveness we studied competitiveness in volleyball basketball and handball we developed a theoretical model based on the model proposed by bernard and busse 2004 to analyse the effect of regional institutions and sport environments that can interfere with sports competitiveness to test our model we constructed an enlarged database for all european nuts2 since 1995 which we analysed using panel data techniques censored tobit models our results reveal that the regions that are able to maintain player performance do so by persistent effort and external influences these factors contribute more to regional competitiveness than a region s central location or political prominence

competitive balance versus competitive intensity before a match is one of these two concepts more relevant in explaining attendance the case of the french football ligue 1 over the period 2008 2011 the aim of this article is to investigate the determinants of attendance at french football ligue 1 matches over the period 2008 2011 with an emphasis on examining the effects of both competitive balance and intensity before a match competitive balance is measured by the point difference between the two teams concerned by a match in the championship competitive intensity is measured by the point difference for the home team in relation to ranks with sporting stakes results show that competitive balance has an insignificant impact whereas competitive intensity has a significantly positive impact implications are drawn

performance evaluation of the english premier football league with data envelopment analysis this paper uses data envelopment analysis dea to evaluate the performance of english premier league football clubs from 1998 99 to 2002 03 combining sport and financial variables the paper evaluates how close the clubs are relative to the frontier of best practices analysing how they manage sport as well as financial results managerial implications of the research are devised

sport event attendance as a function of education evidence from the uk abstractthis article studies the role of education in the decision to attend sporting events the overall objective is to verify whether more educated individuals are more likely to go to sports events than their less educated counterparts if education socializes persons to focus on sports it would then partially offset negative alternatives such as alcohol drug abuse and unlawful behaviours creating a positive externality sport events consumption is extensive highlighting the potential economic importance of the sports education externality to establish the role of education in sport attendance this article applies a probabilistic linear regression model to data from the uk the econometric formulation associates sport event attendance in the left hand side with education in the right hand side while controlling for the socioeconomic variables that are known to affect a consumer s decision to go to a sport event gender age income employment status children marital status and geographical

asymmetry in retail gasoline and crude oil price movements in the united states an application of hidden cointegration technique abstract there is a common belief that gasoline prices respond more quickly to crude oil price increases than decreases some economists and politicians believe that asymmetry in oil and gasoline price movements is the outcome of a non competitive gasoline market requiring that governments take policy action to address unfair pricing there is no consensus as to the existence or nature of the asymmetric relationship between prices of gasoline and crude oil much of this literature specifies asymmetry in the speed of adjustment and short run adjustment coefficients in contrast granger and yoon s granger c w and yoon g hidden cointegration university of california san diego department of economics working paper 2002 crouching error correction model cecm identifies asymmetry of the cointegrating vectors between components cumulative positive and negative changes of the series applying the cecm to retail gasoline and crude oil prices for the u s we find that there is only evidence of cointegration between positive components of crude oil prices and negative components of gasoline prices in contrast to the literature which attributes asymmetric price movements to market power of refiners these findings suggest that gasoline prices in the long run are more influenced by the technological changes on the demand side than crude oil price movements on the supply side

the empirical relationship between energy futures prices and exchange rates abstract this paper investigates the interaction between energy futures prices and exchange rates results are presented to show that futures prices for crude oil heating oil and unleaded gasoline are co integrated with a trade weighted index of exchange rates this is important because it means that there exists a long run equilibrium relationship between these four variables granger causality results for both the long and short run are presented evidence is also presented that suggests exchange rates transmit exogenous shocks to energy futures prices

the effect of professional sports on the earnings of individuals evidence from microeconomic data this article examines the impact of professional sports franchises in labour markets using data from the march supplement to the current population survey cps for workers employed in specific occupational groups in all large us cities from 1983 to 2002 results from a standard wage model suggest that professional football franchises increase average hourly and weekly earnings of males employed in these occupations but professional baseball franchises reduce them these results support growing evidence that professional sports affect labour markets however the mixed nature of the association between sport and earnings provides little economic justification for government subsidies for professional sport

price relationships in the petroleum market an analysis of crude oil and refined product prices in this paper the relationships between crude oil and refined product prices are investigated in a multivariate framework this allows us to test several partly competing assumptions of earlier studies in particular we find that the crude oil price is weakly exogenous and that the spread is constant in some but not all relationships moreover the multivariate analysis shows that the link between crude oil prices and several refined product prices implies market integration for these refined products this is an example of supply driven market integration and producers will change the output mix in response to price changes

co integration of ice gas oil and crude oil futures abstract in this paper the relationship between gas oil and brent crude oil futures prices is investigated the analysis is based on daily price series for five different contract lengths traded on ice futures europe the price series and their first differences are tested for stationarity linear relationships between the pair wise gas oil and crude oil contracts are then tested for co integration a co integrated relationship is found for the 1 and 2 month contracts covering data from 1994 to 2009 and error correction models are established to estimate the relationships no co integrated relationships are found for the 3 6 and 12 month contracts covering the period 2002 2009 nor for the 1 and 2 month contracts for this period the futures prices for this period are collected from a volatile market including hurricane katrina the economic boom and the following financial crises which might explain these results thus in such volatile periods the spread between gas oil and crude oil is likely to deviate and it might take several years until it reverts to its equilibrium value for energy traders and hedgers this will imply that exposures to the crack spread should be treated with great care in such market environments

correlation between chinese and international energy prices based on a hp filter and time difference analysis abstract to establish a reasonable system and mechanism for chinese energy prices we use the granger causality test hodrick prescott hp filter and time difference analysis to research the pricing relationship between chinese and international energy prices we find that chinese and international crude oil prices changed synchronously while chinese refined oil prices follow the changes of international oil prices with the time difference being about 1 month to 2 months further australian coal prices granger causes chinese coal prices and there is a high correlation between them the u s electricity price is influenced by the wti crude oil price the u s gasoline price and the henryhub gas price due to the unreasonable price setting mechanism and regulation from the central government china s terminal market prices for both electricity and natural gas do not reflect the real supply demand situation this paper provides quantitative results on the correlation between chinese and international energy prices to better predict the impact of international energy price fluctuations on china s domestic energy supply and guide the design of more efficient energy pricing policies moreover it provides references for developing countries to improve their energy market systems and trading and to coordinate domestic and international energy markets

expenditure elasticities of the demand for leisure services although some research has already focused on the analysis of expenditure elasticities of leisure demand some shortcomings with regard to the content and the underlying theoretical model as well as the applied methods exist this article aims at avoiding these problems to provide consistent derivatives of leisure service expenditure elasticities therefore a regular demand system is derived from microeconomic duality theory to implement leisure specific demand factors i e demand and supply based sports and recreational opportunities as well as sports and recreational preferences while still being consistent with neoclassical demand theory the basic model is extended by applying the demographic translation framework data of the continuous household budget survey n 7724 from germany is used for the estimation of the derived demand system it is shown how sensitive the results are depending on the applied censored regression model 16 out of 18 analysed services are indicated as luxury goods b

estimating the speed of adjustment to target levels the case of energy prices in this paper we propose a model that estimates the speed of energy price adjustment to its target level we also explain the source of price adjustment moreover we extract energy price bubbles and show that bubbles help explain price adjustment since ours is the first paper that develops an energy price adjustment model and links it to bubbles several avenues for future research have emerged from our analysis the first is to provide a theoretical framework for the bubbles and price adjustment mechanism the second direction of research will be to continue the search for other potential determinants of price adjustment

the cyclical behavior of monthly nymex energy prices abstract this paper systematically investigates the basic stylized facts of energy price movements using monthly data for the period that energy has been traded on organized exchanges and the methodology suggested by kydland and prescott kydland f e prescott e c 1990 business cycles real facts and a monetary myth fed reserve bank minneapolis q rev spring 3 18 the results indicate that energy prices are in general procyclical in contrast to the accepted fact that energy prices are countercyclical and leading the cycle

measuring competitive balance in sports using generalized entropy with an application to english premier league football a central issue in the economics of sport is the degree of competitive balance in sporting contests the importance attached to competitive balance is predicated on the belief that it is uncertainty about the outcomes of sporting contests that attracts spectators and sponsors in a perfectly balanced competition each team would have an equal chance of winning each match and therefore of winning the championship or the league by contrast the absence of competitive balance would mean that the results of sporting contests would become predictable and attendance at sporting contests would suffer the general theme that underpins the issue of competitive balance is that of inequality this article proposes a general measure of competitive balance based on the generalized entropy ge approach to measuring inequality and shows how this might be interpreted in terms of the league s welfare the measures are applied to results from 2006 to 2007 season of the english premier league epl

international evidence on the size of the random walk in output this paper contributes three extensions of cochrane s work on measuring the relative stability of long term growth it estimates variance ratios for nine oecd countries over the period 1871 1985 presents an improved approximation to the distribution of the variance ratio and considers the comovements of long growth cycles across countries the evidence indicates that the relative stability of long term growth found by cochrane is unique to the united states relative to the united states most countries have more variable dynamics at low frequencies and smoother dynamics at frequencies traditionally associated with business cycles

an empirical model comparison for valuing crack spread options in this paper we investigate the pricing of crack spread options particular emphasis is placed on the question of whether univariate modeling of the crack spread or explicit modeling of the two underlyings is preferable therefore we contrast a bivariate garch volatility model for cointegrated underlyings with the alternative of modeling the crack spread directly conducting an empirical analysis of crude oil heating oil and crude oil gasoline crack spread options traded on the new york mercantile exchange the more simplistic univariate approach is found to be superior with respect to option pricing performance

capital energy substitution evidence from a panel of irish manufacturing firms abstract we use a translog cost function to model production in the irish manufacturing sector over the period from 1991 to 2009 we estimate both own and cross price elasticities and morishima elasticities of substitution between capital labour materials and energy we find that capital and energy are substitutes in the production process across all firms we find that a 1 rise in the price of energy is associated with an increase of 0 04 in the demand for capital the morishima elasticities which reflect the technological substitution potential indicate that a 1 increase in the price of energy causes the capital energy input ratio to increase by 1 5 the demand for capital in energy intensive firms is more responsive to increases in energy prices while it is less responsive in foreign owned firms we also observe a sharp decline in firms responsiveness in the first half of the sample period

technical efficiency of european railways a distance function approach this study has two principal objectives the first objective is to measure and compare the performance of european railways the second objective is to illustrate the usefulness of econometric distance functions in the analysis of production in multioutput industries where behavioural assumptions such as cost minimization or profit maximization are unlikely to be applicable using annual data on 17 railways companies during 1988 1993 multioutput distance functions are estimated using corrected ordinary least squares cols the resulting technical efficiency estimates range from 0 980 for the netherlands to 0 784 for italy with a mean of 0 863 the distance function results are also compared with those obtained from single output production functions where aggregate output measures are formed using either total revenue or a tornqvist index the results obtained indicate substantial differences in parameter estimates and technical efficiency rankings casting significant doubt upon the reliability of

price dynamics of crude oil and the regional ethylene markets abstract this paper is the first attempt to investigate i is the crude oil wti price significantly related to the regional ethylene prices in the naphtha intensive ethylene markets of the far east north west europe and the mediterranean ii what drives the regional ethylene prices the paper is motivated by the recent and growing debate on the lead lag relationship between crude oil and ethylene prices our findings based on the long run structural modelling approach of pesaran and shin and subject to the limitations of the study tend to suggest i crude oil wti price is cointegrated with the regional ethylene prices ii our within sample error correction model results tend to indicate that although the ethylene prices in north west europe and the mediterranean were weakly endogenous the far east ethylene price was weakly exogenous both in the short and long term these results are consistent during most of the period under review 2000 1 2006 4 with the surge in demand for ethylene throughout the far east particularly in china and south korea however during the post sample forecast period as evidenced in our variance decompositions analysis the emergence of wti as a leading player as well is consistent with the recent surge in wti price fuelled mainly among others by the strong hedging activities in the wti futures options and refining tightness reflecting the growing importance of input cost in determining the dynamic interactions of input and product prices

hedgers funds and small speculators in the energy futures markets an analysis of the cftc s commitments of traders reports the commodity futures trading commission cftc s commitments of traders cot data are examined for crude oil unleaded gasoline heating oil and natural gas futures contracts the collection procedures for the cot data are first examined followed by granger causality tests to determine if relationships between trader positions and market prices exist a positive correlation between returns and positions held by noncommercial traders and a negative correlation between commercial positions and market returns are found furthermore positive returns result in an increase in noncommercial net positions in the following week whereas the net long positions held by commercial hedgers decline following price increases however traders net positions do not lead market returns in general

a performance assessment of the angolan soccer league abstractthis article analyses the technical efficiency of the angolan soccer league from 2008 to 2014 using a translog distance stochastic frontier model the greene stochastic frontier model presented in 2005 and kumbhakar stochastic frontier model presented in 1990 are adopted and the covariates used include luanda location funding by the oil company sonangol club supported by rich fans and club relegated during the period policy implications are then derived
