a study on the future of unconventional oil development under different oil price scenarios a system dynamics approach abstract fluctuations in the oil global market has been a critical topic for the world economy so that analyzing and forecasting the conventional oil production rate has been examined by many researchers thoroughly however the dynamics of the market has not been studied systematically with regard to the new emerging competitors namely unconventional oil in this paper the future trend of conventional and unconventional oil production and capacity expansion rates are analyzed using system dynamics approach to do so a supply side modeling approach is utilized while main effective loops are modeled mathematically as follows technological learning and progress long and short term profitability of oil capacity expansion and production and oil proved reserve limitations the proposed model is used to analyze conventional and unconventional oil production shares up to 2025 under different oil price scenarios the results show that conventional oil production rate ranges from 79 995 to 87 044 mb day which is 75 80 percent of total oil production rate while unconventional oil production rate ranges from 19 615 to 28 584 mb day simulation results reveal that unconventional oil can gain a considerable market share in the short run although conventional oil will remain as the major source for the market in the long run

quantitative effects of the shale oil revolution abstract the aim of this paper is to analyze the impact of the so called shale oil revolution on oil prices and economic growth we employ a general equilibrium model of the world oil market in which saudi arabia is the dominant firm with the rest of the producers as a competitive fringe our results suggest that most of the expected increase in us oil supply due to the shale oil revolution has already been incorporated into prices and that it will produce an additional increase of 0 2 in the gdp of oil importers in the period 2010 2018 we also employ the model to analyze the collapse in oil prices in the second half of 2014 and conclude that it was mainly due to positive unanticipated supply shocks

the evolution of high incomes in northern america lessons from canadian evidence this paper uses tax statistics to construct new series on canadian top income shares from 1920 to 2000 and provides a systematic comparison with the u s experience as in the united states top income shares in canada display a ushaped pattern over the century with a precipitous drop during world war ii followed by a slower decline until 1970 since the late 1970s top income shares have been increasing dramatically and the very top shares are now as high as in the pre war era as in the united states the recent increase in top income shares is the consequence of a surge in top wages and salaries the canadian experience since the late 1970s does not appear to be well explained by tax changes suggesting that the upward trend in canada derives from the united states perhaps because many high income canadians have an emigration option this in turn suggests that the recent increase in u s personal income top shares is not merely a change in tax reporting behavior the recent sharp increase in top income shares in canada is of the same magnitude at the individual and family level and is not due to an increase in income mobility

the incidence of income taxes on high earners in canada this article explores the brain drain explanation for the concentration of incomes in canada during the past 30 years namely that high skilled canadians make use of high salaries on offer in the united states to extract higher salaries at home if this is the case then for a given level of us salaries the threat to accept outside offers should be more credible when the canadian dollar is depreciating against the us dollar and weaker when the canadian dollar is appreciating the data are broadly consistent with this claim income concentration worsened during the depreciations of the 1980s and 1990s and eased when the canadian dollar began to appreciate in value the article develops a simple two parameter model based on the propositions that high earners in canada can use us salaries to bargain for higher salaries and that canadian high earners can shelter part of their income from personal income taxes it also offers some preliminary evidence about the parameter values consistent with available data the results suggest that higher top marginal personal income tax rates may potentially accentuate top end after tax income inequality if high earners are able to use their bargaining power to extract pay increases to offset higher tax rates then the burden of increased personal income taxes will be deflected elsewhere and may even have the perverse effect of making the after tax income distribution more unequal than it was before l incidence des impots sur le revenu des hauts salaries au canada cet article examine l hypothese des produits de base produits de base produits de base produits de base produits de base fuites des cerveaux comme explication pour la concentration des revenus au canada pendant les dernieres decennees c est a dire que les canadiens hautement qualifies se servent des salaires offerts aux etats unis pour negocier des salaires plus eleves au canada si tel est le cas la menace d emigrer aux etats unis est plus credible lorsque le dollar canadien deprecie contre le dollar americain et elle est moins credible pendant une appreciation les grandes lignes des variations des donnees vont dans le sens de cette conjecture la concentration des revenus a accru pendant les depreciations des annees 1980 et 1990 et cette tendance a renverse la direction suite a l appreciation du dollar canadien l article developpe un modele a deux parametres base sur les propositions que les hauts salaries au canada peuvent utiliser les salaires aux etats unis afin de negocier des salaires plus eleves et que les hauts salaries se servent de la planification fiscale afin de mettre une partie de leurs revenus a l abri des impots des estimations preliminaires pour les parametres sont presentees les resultats suggerent qu une augmentation du taux marginal d imposition pourrait meme accentuer l inegalite des revenus apres impots si les hauts salaries sont capables de negocier des salaires plus eleves face aux augmentations des taux d imposition le fardeau du nouvel impot serait refile ailleurs la distribution des revenus nets pourrait meme devenir encore plus inegale

from theory to practice canadian economists contributions to public finance we survey canadian economists contributions to the field of public finance from the mid 1980s to 2016 we highlight the development and extension of the models and tools of public economics and the empirical studies that have deepened our understanding of the efficiency and distributional issues over a wide range of public finance issues we also highlight contributions to the development of policies through commissioned reports and the important role that canadian institutions the canadian tax foundation the think tanks and the federal and provincial departments of finance have played in shaping tax and fiscal policies de la theorie a la pratique contributions des economistes canadiens a la finance publique on examine les contributions des economistes canadiens au domaine de la finance publique du milieu des annees 1980 a 2016 on souligne le developpement et l extension des modeles et des outils d economie publique et les etudes empiriques qui ont aide a approfondir notre comprehension des enjeux d efficacite et de distribution dans un vaste eventail de questions de finance publique on souligne aussi les contributions des rapports commandites au developpement de politiques publiques ainsi que le role important d institutions canadiennes l association canadienne d etudes fiscales les groupes d experts ainsi que les ministeres des finances du gouvernement federal et des gouvernements provinciaux dans le design des politiques fiscales

oil price volatility financial institutions and economic growth abstract theory attributes finance with the ability to both promote growth and reduce output volatility and therefore increase energy security but evidence is mixed partly due to endogeneity effects for example financial institutions themselves might be a source of volatility as the events of 2008 suggest we address this endogeneity issue by using periods of extreme oil price volatility as a source of nearly exogenous volatility to study the effect of finance to do this we develop a quasi natural experiment and study the effect of the dramatic decline of oil prices in 2014 using a synthetic control methodology our hypothesis is that the ability of oil rich countries to mitigate the effects of this decline rested on the quality of their financial institutions we focus on 11 oil rich countries between 2006q1 and 2016q4 that had poor measures of financial development treatment group out of 20 such countries and synthetically create counterfactuals from the remaining control group with superior financial development we subject both to the oil price shock of 2014 and find evidence that better financial institutions do indeed reduce output volatility and mitigate its negative effect on growth in the year that showed a sustained decline in oil price to address any remaining potential endogeneity between oil prices and finance we use a cross sectionally augmented autoregressive distributed lag model with data on 30 oil producing countries over the period 1980 2016 and confirm that the effects of oil volatility on growth is mitigated with better financial institutions our results make a strong case for the support of the positive role of financial development in improving energy security and fostering growth

the optimal elasticity of taxable income abstract the strength of the behavioral response to a tax rate change depends on the environment individuals operate in and may be manipulated by instruments controlled by the government we first derive a measure of the social benefit to affecting this elasticity the paper then examines this effect in the solution to the optimal income taxation problem when such an instrument is available first in a general model and then in an example when the government chooses the income tax base

profits risk and uncertainty in foreign exchange markets this paper examines the properties of nominal profits from speculation in dollar dominated forward contracts using a representative agent cash in advance model modified to allow for heteroscedasticity in the exogenous processes the model is simulated by estimating exogenous processes from the data and the remaining free parameters with a simulated method of moments technique simulated expected profits are variable heteroskedastic and serially correlated but the magnitude of these second moments fall short of those of the predictable component of observed profits on the u s dollar as in the actual data simulated forward rates display biasedness in predicting simulated future spot rates

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

what determines china s crude oil importing trade patterns empirical evidences from 55 countries between 1992 and 2015 abstract this study develops a conceptual framework that synthesizes the supply demand price and openness of crude oil trade along with a list of traditional economic political and geographical factors to investigate the determinants of crude oil imports in emerging markets we test the framework using china s crude oil imports from 55 countries for the period from 1992 to 2015 using both static and dynamic panel data models we find that china s crude oil import is associated with exporting country s supply demand and price as well as its bilateral trade relationships these factors were found to affect china s import of crude oil from the middle east however only bilateral trade relationships affect its imports of crude oil from the asia pacific furthermore we do not find substantial evidence in this research to indicate that china s direct investment increases crude oil imports from those countries this article is part of a virtual special issue entitled comparing sustainable energy policies in northeast asia toward the harmonized public private partnership

top income shares in canada recent trends and policy implications according to canadian taxfiler data over the last thirty years there has been a surge in the income shares of the top 1 top 0 1 and top 0 01 of income recipients even with longitudinal smoothing by individual using three or five year moving averages top shares fell in 2008 and 2009 but only by a fraction of the overall surge alberta british columbia and ontario have much more pronounced surges than other provinces part of the canadian surge is likely attributable to u s factors but a comprehensive explanation remains elusive even so i draw implications for policies that might achieve some support from across the political spectrum including the elimination of tax preferences that favour those with high incomes the promotion of shareholder democracy and to maintain canada s relatively high intergenerational mobility continued wide accessibility to healthcare and education

the effect of marginal tax rates on taxable income a panel study of the 1988 tax flattening in canada abstract federal tax reform in 1988 flattened the canadian personal income tax schedule changing the marginal tax rates for many individuals using methods similar to those applied by auten and carroll rev econ 81 4 1999 681 in the study of the effects of the 1986 u s tax reform act we estimate the responsiveness of income to changes in taxes to be substantially smaller in canada however we find evidence of a much higher response in self employment income in the labor income of seniors and from those with high incomes

the elasticity of taxable income with respect to marginal tax rates a critical review this paper critically surveys the large and growing literature estimating the elasticity of taxable income with respect to marginal tax rates using tax return data first we provide a theoretical framework showing under what assumptions this elasticity can be used as a sufficient statistic for efficiency and optimal tax analysis we discuss what other parameters should be estimated when the elasticity is not a sufficient statistic second we discuss conceptually the key issues that arise in the empirical estimation of the elasticity of taxable income using the example of the 1993 top individual income tax rate increase in the united states to illustrate those issues third we provide a critical discussion of selected empirical analyses of the elasticity of taxable income in light of the theoretical and empirical framework we laid out finally we discuss avenues for future research jel h24 h31 j22

changing beliefs and systematic rational forecast errors with evidence from foreign exchange this paper addresses a new interpretation to the appearance in the early 1980s of systematic errors in forecasting the dollar exchange rate following a change in the process of a fundamental variable market participants revise their beliefs about the process using bayes rule since the market does not immediately recognize the change forecast errors are on average wrong during a period when the market is rationally learning for conservative parameter values the learning behavior of the dollar exchange rate in the early 1980s appears consistent with about half of the dollar s underprediction implied by the forward market copyright 1989 by american economic association

the effect of marginal tax rates on taxable income a panel study of the 1986 tax reform act this paper uses a treasury department panel of more than 4 000 taxpayers to estimate the sensitivity of taxable income to changes in tax rates on the basis of a comparison of the tax returns of the same individual taxpayers before and after the 1986 tax reform the analysis emphasizes that the response of taxable income involves much more than a change in the traditional measures of labor supply the evidence shows an elasticity of taxable income with respect to the marginal net of tax rate that is at least one and could be substantially higher the implications for recent tax rate changes are discussed

time and frequency dynamics of connectedness between renewable energy stocks and crude oil prices abstract this paper examines the time and frequency dynamics of connectedness among stock prices of u s clean energy companies crude oil prices and a number of key financial variables using the methodology developed by barunik and krehlik 2018 this approach allows measuring the dynamics of return and volatility connectedness over time and across frequencies simultaneously the empirical results show that most of return and volatility connectedness is generated in the very short term i e movements up to five days while the long term plays a minor role our analysis further reveals a greater degree of interconnectedness across crude oil and financial markets since the onset of the u s subprime mortgage crisis in summer of 2007 consistent with the view of a global re pricing of risk triggered by the recent worldwide financial crisis crude oil prices do not appear as a key driver of the stock market performance of renewable energy companies in the short term or the long term which suggests a decoupling of the alternative energy industry from the traditional energy market moreover crude oil prices are a net receiver of financial shocks supporting the financialization of the commodity markets since the early 2000s in addition a significant pairwise connectedness is found mainly in the short term between clean energy and technology stock prices indicating that these two types of stocks are perceived by investors as similar assets these results can have important practical implications for investors and policy makers with different time horizons

production costs of global conventional and unconventional petroleum abstract concerns about the costs of developing oil and gas from conventional and unconventional formations have led many commentators to assume that increasing prices are in the offing and may be a limiting factor for economic growth historically production costs have fluctuated as influenced by the cost increasing effects of depletion versus the cost reducing effects of technological progress this paper aims to review several methods for assessing current and long term costs despite the uncertainty of such estimation evidence shows that production costs in the foreseeable future might not increase dramatically and actually could decrease as petroleum development methods improve and additional supplies come online recent examples include the commercially viable production of unconventional oil and gas resources that has kept energy prices contained

top incomes in the long run of history a recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics top incomes represent a small share of the population but a very significant share of total income and total taxes paid hence aggregate economic growth per capita and gini inequality indexes are sensitive to excluding or including top incomes we discuss the estimation methods and issues that arise when constructing top income share series including income definition and comparability over time and across countries tax avoidance and tax evasion we provide a summary of the key empirical findings most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks top income shares do not recover in the immediate postwar decades however over the last thirty years top income shares have increased substantially in english speaking countries and in india and china but not in continental european countries or japan this increase is due in part to an unprecedented surge in top wage incomes as a result wage income comprises a larger fraction of top incomes than in the past finally we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open

can energy price regulations smooth price fluctuations evidence from china s coal sector abstract due to the dominance of coal in china s energy mix coal prices have always been a challenging part of pricing reform the recent frequent government interventions raise the key research questions what is the actual impact of price policies on coal price fluctuations and how can forward looking pricing policies be made by proposing a novel classification of coal pricing policies and introducing an expectation and forward looking coefficient the paper examines the relationship between coal price fluctuations and pricing policies using the generalized method of moments gmm method it shows that the lagging coal price and coal demand play a positive role in regulating coal prices while coal supply and marketization have significantly negative effects on coal price fluctuations the heterogeneous impacts of price policies are due to differences in market players expectations policy instruments and the methods of policy release in addition china s coal pricing policy portfolio from 2013 to 2016 exerted synergy effects on the restraint of coal price fluctuations as the forward looking coefficient was considerably low the government s intervention behaviors were obviously biased towards ex post facto responses the paper suggests short run and long run policies to advance marketization of coal prices amid the energy transition

volatility persistence in crude oil markets financial market participants and policy makers can benefit from a better understanding of how shocks can affect volatility over time this study assesses the impact of structural changes and outliers on volatility persistence of three crude oil markets brent west texas intermediate wti and organization of petroleum exporting countries opec between january 2 1985 and june 17 2011 we identify outliers using a new semi parametric test based on conditional heteroscedasticity models these large shocks can be associated with particular event patterns such as the invasion of kuwait by iraq the operation desert storm the operation desert fox and the global financial crisis as well as opec announcements on production reduction or us announcements on crude inventories we show that outliers can bias i the estimates of the parameters of the equation governing volatility dynamics ii the regularity and non negativity conditions of garch type models garch igarch figarch and hygarch and iii the detection of structural breaks in volatility and thus the estimation of the persistence of the volatility therefore taking into account the outliers on the volatility modelling process may improve the understanding of volatility in crude oil markets

taxation and top incomes in canada we estimate the elasticity of reported income with respect to tax rates for high earners using sub national variation across canadian provinces we argue this allows for better identification of tax elasticities than the existing literature we find that elasticities of reported income at the provincial level are large for incomes in the top 1 but small for lower earners there are strong indications that the response happens both through earned and capital income while our estimated elasticities are large changes in tax rates cannot explain much of the overall long run trend of higher income concentration in canada resume fiscalite et revenus les plus eleves au canada les auteurs evaluent l elasticite du revenu declare par rapport aux taux d imposition pour les revenus les plus eleves en utilisant les variations intra nationales a travers les provinces du canada ils suggerent que cela produit une meilleure identification des elasticites que ce que contient la litterature pour le moment on decouvre que les elasticites du revenu declare sont elevees pour les 1 au sommet mais faibles pour les revenus plus bas il appert fortement que la reponse se produit tant pour les revenus gagnes que pour les revenus d investissement meme si les elasticites mesurees sont elevees les changements dans les taux d imposition ne peuvent pas expliquer beaucoup de la tendance a long terme vers une plus forte concentration des hauts revenus au canada

opec and world oil security abstract on the margin the effectiveness of policy to enhance the stability of world oil market oil conditions greatly depends on which countries supply what economists would call the marginal barrels that is the barrels whose production responds to changes in demand if the countries dominating the production of the marginal barrels are relatively unstable policies to reduce world oil consumption or boost oil production from stable suppliers will provide the additional benefit of reducing the contribution of unstable producers to the world oil market if the countries dominating the marginal barrel are relatively stable however policies to reduce world oil consumption or boost oil production from stable suppliers will be less effective in promoting oil market stability typically we think of the highest cost producers as supplying the marginal barrel of oil but our assessment finds it quite likely that opec dominates production of the marginal barrel of world oil moreover opec members have been among the more unstable producers on a historical basis hence reducing world oil consumption and promoting oil production in stable non opec countries will enhance world oil security policies to promote stability in opec countries also would enhance world oil security

effects of oil price fall on the betas in the unconventional oil gas industry abstract we examine the consequences of the oil prices movements started in july 2014 on the financial systematic risk proxied by betas of firms operating in the unconventional oil gas industry compared to that of the conventional oil gas players the analysis is developed using two cross section regressions performed before and after the 2014 oil price drop respectively the results look coherent with the reasonable belief that a sharp and sudden decrease in the oil price can generally lead to higher betas in the oil gas industry interestingly it emerged that the market tends to attribute an additional risk to unconventional firms and analyzing the regression coefficients evolution it appears that this circumstance has been substantially amplified by the 2014 oil price shock to our knowledge this is the first paper covering the topic treated
