distributional effects of a carbon tax in broader u s fiscal reform abstract this paper analyzes the distributional implications of an illustrative 15 carbon tax imposed in 2010 on carbon in fossil fuels we analyze its incidence across income classes and regions both in isolation and when combined with measures that apply the carbon tax revenue to lowering other distortionary taxes in the economy consistent with earlier findings we find that a carbon tax is regressive using tax swap simulations we then subtract the burden of other taxes the carbon tax revenue could displace and compute the net effect on households under three assumptions about how capital and labor income might be distributed

conditional eurobonds and the eurozone sovereign debt crisis this paper proposes that all new euro area sovereign borrowing be in the form of jointly guaranteed eurobonds to avoid classic moral hazard problems and to insure the guarantors against default each country would pay a risk premium conditional on economic fundamentals to a joint debt management agency this suggests that these bonds be called euro insurance bonds while the sovereign debt markets have taken increasing account of the economic fundamentals the signal to noise ratio has been weakened by huge market volatility so undercutting incentives for appropriate reforms and obscuring economic realities for voters this paper uses an econometric model to show that competitiveness public and private debt to gdp and the fall out from housing market crises are the most relevant economic fundamentals formula based risk spreads based on these fundamentals would provide clear incentives for governments to be more oriented towards economic reforms to promote long run growth than mere fiscal contraction putting more weight on incentives that come from risk spreads than on fiscal centralization and the associated heavy bureaucratic procedures would promote the principle of subsidiarity to which member states subscribe the paper compares euro insurance bonds incorporating these risk spreads with other policy proposals copyright 2013 oxford university press

determining the optimal carbon tax rate based on data envelopment analysis carbon tax policy is widely used to control greenhouse gases and how to determine a suitable carbon tax rate is very important for policy makers considering the trade off between environmental protection and economic development in an industry regulated by carbon tax policy we consider two competing firms who sell ordinary products and green products respectively in order to promote the firm who sells ordinary product to reduce carbon emissions the government of china imposes carbon tax on the ordinary products for the government three objectives are considered when it makes carbon tax policy they are increasing the government revenue reducing the government expenditure and decreasing the carbon emissions for the firms it is important to explore their pricing strategies taken into account of the government tax policy to find an optimal carbon tax rate and to achieve the three objectives simultaneously we consider this as a multiple criteria decision making problem hence we propose to use a centralized data envelopment analysis dea approach to solve it we find that when one firm produces ordinary products and the other produces green products the government may set a high tax rate while when both firms sell ordinary products the optimal tax policy for each firm is different and the government may impose a higher tax rate for one firm and a lower tax rate for the other firm

one security many markets determining the contributions to price discovery when homogeneous or closely linked securities trade in multiple markets it is often of interest to determine where price discovery the incorporation of new information occurs this article suggests an econometric approach based on an implicit unobservable efficient price common to all markets the information share associated with a particular market is defined as the proportional contribution of that market s innovations to the innovation in the common efficient price applied to quotes for the thirty dow stocks the technique suggests that the preponderance of the price discovery takes place at the new york stock exchange nyse a median 92 7 percent information share although most of the classic paradigms in market microstructure concern a security that trades in a single centralized market such situations are becoming increasingly rare in practice fragmentation the dispersal of trading in a security to multiple sites has emerged as a dominant institutional trend this process is of concern to financial economists and regulators because price information and price discovery the impounding of new information into the security price arguably the most important products of a security market have many attributes of public goods as the process of fragmentation accelerates it may be important to determine where the price information and price discovery are being produced 1 this paper suggests a practical econometric approach to this problem the technique is illustrated with an application to u s equity markets many stocks listed on the new york stock exchange nyse trade concurrently on the regional exchanges and the national association of securities dealers national market system nasd nms since a share of ibm stock is the same security whether purchased on the midwest or pacific exchange this is a particularly clear instance of multiple markets nevertheless the expres

the impact of distressed economies on the eu sovereign market financially distressed economies inside the european union eu are being blamed for producing a general increase in borrowing costs this article analyzes the channels of default risk transmission within the eu countries using the information content in the sovereign credit default swap cds market we proceed in two directions first we test the existence of cross border volatility effects between the central and the peripheral eu countries second we explore the effect of distressed economies on the default and risk premium constituents of sovereign default swaps we show a significant volatility spillover from distressed to central european economic and monetary union emu economies this causality pattern leads to a significant impact on the default swap risk premia on average the risk premium accounts for approximately 42 of central emu spreads and 56 of the spreads for those countries outside of the emu the peripheral risk also affects the default component of central economies although its impact is lower

heterogeneous market beliefs fundamentals and the sovereign debt crisis in the eurozone type main xml id ecca12155 abs 0001 the unprecedented sovereign debt crisis across the eurozone has prompted a new generation of models with self fulfilling attacks on public debt the model presented in this paper shows that multiple equilibria arise as investors have no direct information and form heterogeneous rational beliefs about the government s sustainable limit of the solvency primary balance if beliefs of insolvency are sufficiently large then the government is bound to default although initial solvency conditions are satisfied several issues are discussed concerning the role of initial conditions fiscal shocks and the policy options to escape from the default domain

the distributional incidence of the gasoline tax in chile abstract this paper analyzes the distributional incidence of the excise tax on gasoline in chile using household budget surveys the incidence is calculated with respect to both income and expenditure distributions in order to consider the potential differences between transitory and permanent income the suits index is estimated as a measure of the degree of progressivity of the tax and confidence intervals are calculated using a bootstrap methodology to statistically compare changes in the incidence given changes in the tax the results show that the tax contrary to the evidence for several developed countries is slightly or moderately progressive with a lower degree of progressivity observed in the calculations based on income than those based on expenditure the simulation of the 25 reduction in the tax rate implemented in 2008 shows that in terms of incidence its effect is to reduce the progressivity of the gasoline tax which is the opposite of what was sought by the government with this policy

price movements and price discovery in futures and cash markets r isk transfer and price discovery are two of the major contributions of futures markets to the organization of economic activity working 1962 evans 1978 p 80 and silber 1981 risk transfer refers to hedgers using futures contracts to shift price risk to others price discovery refers to the use of futures prices for pricing cash market transactions working 1948 wiese 1978 p 87 and lake 1978 p 161 the significance of both contributions depends upon a close relationship between the prices of futures contracts and cash commodities this paper examines the characteristics of price movements in cash or spot markets and futures markets for storable commodities section ii presents an analytical model of simultaneous price dynamics which suggests that over short intervals of time the correlation of price changes is a function of the elasticity of arbitrage between the physical commodity and its counterpart futures contract greater elasticity fosters more highly correlated price changes and thereby facilitates the risk transfer function the elasticity of supply of arbitrage services is constrained by among other things storage and transaction costs thus futures contracts will not in general provide perfect risk transfer facilities over short time horizons the essence of the price discovery function of futures markets hinges on whether new information is reflected first in changed futures prices or in changed cash prices hoffman 1932 pp 258259 the model in section ii provides a framework for analyzing whether one market is dominant in terms of information flows and price discovery in section iii we develop a model based on section ii which is appropriate for estimating the lead lag relationship between cash prices and futures prices section iv presents empirical estimates of the parameters of the model for seven different storable commodities wheat corn oats frozen orange juice concentrates copper gold and silver the cost of arbitrage between cash and futures differs across these commodities for this reason we are not surprised to find inter commodity differences in the correlation of short run price changes and in the substitutability of futures contracts for cash market positions with respect to the price discovery function of futures markets we find that while futures markets dominate cash markets cash prices do not merely echo futures prices there are reverse information flows from cash markets to futures markets as well

uncovering the common risk free rate in the european monetary union summary we introduce longitudinal factor analysis lfa to extract the common risk free crf rate from a sample of sovereign bonds of countries in a monetary union since lfa exploits the typically very large longitudinal dimension of bond data it performs better than traditional factor analysis methods that rely on the much smaller cross sectional dimension european sovereign bond yields for the period 2006 2011 are decomposed into a crf rate a default risk premium and a liquidity risk premium our empirical findings suggest that investors chase both credit quality and liquidity and that they price double default risk on credit default swaps copyright 2013 john wiley sons ltd

option prices as predictors of equilibrium stock prices the black scholes option pricing model modified for dividend payments is used to calculate jointly implied stock prices and implied standard deviations a comparison of the implied stock prices with observed stock prices reveals that the implied prices contain information regarding equilibrium stock prices that is not fully reflected in observed stock prices the implications of this finding are discussed this study investigates the role of call option prices as predictors of the equilibrium prices of their underlying stocks using the black scholes 3 bs model previous tests of the bs model have shown that the formula is highly successful in explaining the observed market prices of options see black and scholes 2 galai 8 chiras and manaster 6 and macbeth and merville 12 according to the model the option price is a function of the current value of the underlying stock the instantaneous variance of the stock s rate of return the time to maturity of the option the risk free rate of interest and the exercise price of the option 1 given an observed option price and known values of all input parameters to the bs model except the stock price one can determine the price of the underlying stock that equates the observed option price to its calculated value it follows from the underlying logic of the model that the implied price is the value of the underlying stock for which a continuously revised option bond portfolio would be a perfect substitute for the stock hence if options are actually priced according to the model implied stock prices will be the option market s assessment of equilibrium stock values previous empirical studies have assumed that observed stock prices are the relevant stock prices for option valuation however just as stock prices may differ in the short run from one exchange to another i e nyse midwest

how connected is the global sovereign credit risk network abstract this paper estimates the global network structure of sovereign credit risk by applying the diebold yilmaz connectedness methodology on sovereign credit default swaps scdss the level of credit risk connectedness among sovereigns which is quite high is comparable to the connectedness among stock markets and foreign exchange markets in the aftermath of the recent financial crises that originated in developed countries emerging market countries have played a crucial role in the transmission of sovereign credit risk while developed countries and debt ridden developing countries have played marginal roles secondary regressions show that both trade and capital flows are important determinants of pairwise connectedness across countries the capital flows became increasingly important after 2013 while the effect of trade flows decreased during the crisis and did not recover afterwards

carbon tax simulations using a household demand model abstract the main objective of this paper is to analyse consumer response and welfare effects due to changes in energy or environmental policy to achieve this objective we formulate and estimate an econometric model for non durable consumer demand in sweden that utilises micro and macro data in the simulations we consider two revenue neutral scenarios that both imply a doubling of the co2 tax one that returns the revenues in the form of a lower vat and one that subsidise public transport one conclusion from the simulations is that the co2 tax has regional distribution effects in the sense that household living in sparsely populated areas carry a larger share of the tax burden

a chinese sky trust distributional impacts of carbon charges and revenue recycling in china abstract the introduction of carbon charges on the use of fossil fuels in china would have a progressive impact on income distribution this outcome which contrasts to the regressive distributional impact found in most studies of carbon charges in industrialized countries is driven primarily by differences between urban and rural expenditure patterns if carbon revenues were recycled on an equal per capita basis via a sky trust the progressive impact would be further enhanced low income mainly rural households would receive more in sky trust dividends than they pay in carbon charges and high income mainly urban households would pay more than they receive in dividends thus a chinese sky trust would contribute to both lower fossil fuel consumption and greater income equality

residential energy expenditures and the relevance of changes in household circumstances this paper analyses the impact that dwelling characteristics and characteristics and behaviours of household members have on per capita energy expenditures it also analyses whether changes in household socio economic circumstances translate in changes in energy expenditures socio economic characteristics have a moderate impact while dwelling characteristics and especially household size have much larger impacts the largest changes in energy expenditures are due to changes in household size the recent socio demographic trends will make it harder to design policies to effectively reduce the carbon footprint of a country while policies influencing cohabitation and family size may have positive indirect effects

consolidation fragmentation and market performance this paper studies the impact of market consolidation or fragmentation on its performance examining four alternative models of exchange a consolidated clearing house fragmented clearing houses a monopoly dealer market and an interdealer market the effects of the market mechanism on the expected quantity traded the price variance faced by individual traders the quality of market price signals the expected gains from trade and the exchange implementation costs are studied

tracking global carbon revenues a survey of carbon taxes versus cap and trade in the real world abstract we investigate the current use of public revenues which are generated through both carbon taxes and cap and trade systems more than 28 3 billion in government carbon revenues are currently collected each year in 40 countries and another 16 states or provinces around the world of those revenues 27 7 8 billion are used to subsidize green spending in energy efficiency or renewable energy 26 7 4 billion go toward state general funds and 36 10 1 billion are returned to corporate or individual taxpayers through paired tax cuts or direct rebates cap and trade systems 6 57 billion in total public revenue earmark a larger share of revenues for green spending 70 while carbon tax systems 21 7 billion more commonly refund revenues or otherwise direct them towards government general funds 72 of revenues drawing from an empirical dataset we also identify various trends in systems use of carbon revenues in terms of the total revenues collected annually per capita in each jurisdiction and offer commensurate qualitative observations on carbon policy design choices

household welfare and co2 emission impacts of energy and carbon taxes in mexico abstract we analyse the effects of environmental taxes on welfare and carbon emissions at the household level for the case of mexico the integrated welfare environmental analysis which is based on a censored energy consumer demand system extends previous work in two ways first the estimation of a full matrix of substitution elasticities allows us to test the necessity of incorporating second order effects into the welfare analysis second the substitution elasticities derived from the demand system are used to estimate the shortrun co2 emission reduction potential we find that first order approximations of welfare effects provide reasonable estimates particularly for carbon taxes analog to evidence in other low and middle income countries the taxation of all energy items is found to be regressive with the exception of motor fuels the analysis of the emission implications of different tax scenarios indicates that short run emission reductions at the household level can be substantial though the effects depend on how revenue is recycled this effectiveness combined with moderate and manageable adverse distributional impacts renders the carbon tax a preferred mitigation instrument considering the large effect of food price increases on poverty and the limited additional emission saving potential the inclusion of ch4 and n2o in a carbon tax regime is not advisable

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

the dynamics of stock index and stock index futures returns in rational efficiently functioning markets the returns on stock index and stock index futures contracts should be perfectly contemporaneously correlated this study investigates the time series properties of 5 minute intraday returns of stock index and stock index futures contracts and finds that sp however the effect is not completely unidirectional with lagged stock index returns having a mild positive predictive impact on futures returns

measuring sovereign risk spillovers and assessing the role of transmission channels a spatial econometrics approach abstract we contribute to the literature on international risk spillovers by developing a unified framework based on spatial econometrics that enables us to address the following questions i what are the effective transmission channels real linkages and informational channels of international risk spillovers across countries and or regions ii what are the most dominant ones and iii which countries are most at risk for their environment and which are suffering the most from international exposure our analysis based on 41 advanced and emerging economies from 2008q1 to 2012q4 shows that among the considered channels for explaining international spillovers of sovereign bond spreads the informational channel is of utmost importance our results challenge previous findings from the literature in which the empirical strategy did not accommodate altogether important features of country spillovers such as the co existence of multiple transmission channels in the presence of contemporaneous and time lagged interactions ultimately our stress testing analysis reveals important insights on countries prone either to international spillovers international exposure or both at the regional and the worldwide level

what do we learn from the price of crude oil futures summary despite their widespread use as predictors of the spot price of oil oil futures prices tend to be less accurate in the mean squared prediction error sense than no change forecasts this result is driven by the variability of the futures price about the spot price as captured by the oil futures spread this variability can be explained by the marginal convenience yield of oil inventories using a two country multi period general equilibrium model of the spot and futures markets for crude oil we show that increased uncertainty about future oil supply shortfalls under plausible assumptions causes the spread to decline increased uncertainty also causes precautionary demand for oil to increase resulting in an immediate increase in the real spot price thus the negative of the oil futures spread may be viewed as an indicator of fluctuations in the price of crude oil driven by precautionary demand an empirical analysis of this indicator provides evidence of how shifts in the uncertainty about future oil supply shortfalls affect the real spot price of crude oil copyright 2010 john wiley sons ltd

are european sovereign bonds fairly priced the role of modelling uncertainty abstract this paper examines the extent to which large swings of sovereign yields in euro area countries during the debt crisis can be attributed to fundamentals focusing on the inherent uncertainty in bond yield models we show that the outcomes are strongly affected by modelling choices with regard to i the confidence bands for the model prediction ii the assumption whether the model coefficients are similar across countries or not iii the sample selection iv the inclusion of financial variables and v the choice of time varying coefficients these choices affect the explanatory power of macro fundamentals and the extent of mispricing

transmission of government default risk in the eurozone abstract this paper analyzes the reasons behind the rising ten year government bond spreads in the eurozone during the recent euro debt crisis we develop a structural vector autoregressive model that allows us to test whether the upsurges in the spreads reflect breaks in the instantaneous shock propagation mechanisms between the spreads contagion changing dynamical effects or changing country specific risk factors especially a new approach to test the stability of the instantaneous shock propagation mechanisms is introduced our results show that although contagion appears as the single most important reason for the increasing spreads there are notable differences between the countries for example and ireland spain and italy see statistically significant increases in their country specific risk factors

the temporal price relationship between s p 500 futures and the s p 500 index this paper empirically examines the intraday price relationship between s p 500 futures and the s p 500 index using minute to minute data three stage least squares regression is used to estimate lead and lag relationships with estimates for expiration days of the s p 500 futures compared with estimates for days prior to expiration the results suggest that futures price movements consistently lead index movements by twenty to forty five minutes while movements in the index rarely affect futures beyond one minute

a meta analysis on the price elasticity of energy demand abstract price elasticities of energy demand have become increasingly relevant in estimating the socio economic and environmental effects of energy policies or other events that influence the price of energy goods since the 1970s a large number of academic papers have provided both short and long term price elasticity estimates for different countries using several models data and estimation techniques yet the literature offers a rather wide range of estimates for the price elasticities of demand for energy this paper quantitatively summarizes the recent but sizeable empirical evidence to facilitate a sounder economic assessment of in some cases policy related energy price changes it uses meta analysis to identify the main factors affecting short and long term elasticity results for energy in general as well as for specific products i e electricity natural gas gasoline diesel and heating oil

elasticities of electricity demand in urban indian households abstract in the past several electricity demand studies have been published for india based on aggregate macro data at the country or sub national state level since the underlying theory of consumer demand is based on the behaviour of individual agents the use of micro data which reflects individual and household behaviour more closely can shed greater light on the nature of consumer responses in this paper seasonal price and income elasticities of electricity demand in the residential sector of all urban areas of india are estimated for the first time using disaggregate level survey data for about 30 000 households three electricity demand functions have been econometrically estimated using monthly data for the winter monsoon and summer season in order to understand the extent to which factors like income prices household size and other household specific characteristics influence variations observed in individual households electricity demand the results show electricity demand is income and price inelastic in all three seasons and that household demographic and geographical variables are significant in determining electricity demand

a further analysis of the lead lag relationship between the cash market and stock index futures market the intraday lead lag relation between returns of the major market cash index and returns of the major market index futures and s p 500 futures is investigated empirical results show strong evidence that the futures leads the cash index and weak evidence that the cash index leads the futures the asymmetric lead lag relation holds between the futures and all component stocks including those that trade in almost every five minute interval evidence indicates that when more stocks move together market wide information the futures leads the cash index to a greater degree this suggests that the futures market is the main source of market wide information article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

spread the news the impact of news on the european sovereign bond markets during the crisis we investigate how news affected domestic interest spreads vis a vis germany and how it propagated to other countries during the recent crisis period thereby distinguishing between the so called giips countries and other european countries we make original use of the eurointelligence newsflash to construct news variables based on the amount of news that is released on a country on a given date we find that more news on average raises the domestic interest spread of giips countries since september 2009 in addition we find that it leads to an increase in the interest spreads of other giips countries the magnitude of this effect is related to cross border bank holdings a split of news into bad and good news shows that the upward pressure on domestic and foreign interest spreads is driven by bad news we also find spillovers of bad news from giips countries onto non giips countries however the magnitude of these spillovers is substantially smaller than that to other giips countries

which oil shocks really matter in equity markets abstract this paper examines the relationship between structural oil shocks and us equity markets the recent oil shock decomposition of ready 2018 is reconsidered and refined providing a clearer delineation between shocks to equity market discount rates and aggregate demand leading to an oil shock specification which attributes substantially more explanatory power to the latter in explaining equity market variation providing links with the literature dating back to kilian and park 2009 an explicit role is given to precautionary demand shocks using an independent measure constructed from oil futures data reducing the role of the supply shocks obtained as the final residual in the recursive identification scheme in an extended sample that allows an analysis of the oil equity market relationship since the global financial crisis the modified aggregate demand shocks have approximately twice as much explanatory power for stock return variation than the demand shocks of ready 2018 the importance of these shocks in driving oil price changes and equity market volatility has only increased since the financial crisis with the role of supply shocks diminishing once these demand effects are accounted for there is little relationship between precautionary demand shocks and equity returns in contrast to the existing literature

sovereign spreads in the eurozone which prospects for a eurobond in this paper we provide new evidence on the determinants of sovereign yield spreads and market sentiment effects in the eurozone in order to evaluate the rationale for a common eurobond jointly guaranteed by eurozone member states we find that default risk is the main driver of yield spreads suggesting small gains from greater liquidity fiscal fundamentals matter in the pricing of default risk but only as they interact with other countries yield spreads that is with the global risk that the market perceives more importantly the impact of this global risk variable is not constant over time a clear sign of contagion driven by shifts in market sentiment this evidence points to a discontinuity in the disciplinary role of financial markets if markets can stay irrational longer than a country can stay solvent then the role of yield spreads on national bonds as a fiscal discipline device is considerably weakened and issuing eurobonds can be economically justified carlo favero and alessandro missale

sovereign debt guarantees and default lessons from the uk and ireland 1920 1938 abstract we study the daily yields on irish land bonds listed on the dublin stock exchange during the years 1920 1938 we exploit irish events during the period and structural differences in land bonds to tease out a measure of investors credibility in a uk sovereign guarantee using ireland s default on intergovernmental payments in 1932 we find a premium of about 43 basis points associated with uncertainty about the uk government guarantee we discuss the economic and political forces behind the irish and uk governments decisions pertaining to the default our finding has implications for modern day proposals to issue jointly guaranteed sovereign debt further in view of all the historical circumstances it is not equitable that the irish people should be obliged to pay away these moneys eamon de valera 12 october 1932

demographic variables in demand analysis in this paper the authors discuss five procedures for incorporating demographic variables into theoretically plausible demand systems translating scaling and the gorman reverse gorman and implicit prais houthakker procedures these five procedures are used to incorporate a single demographic variable the number of children in a household into the generalized ces demand system using household budget data for the united kingdom for the period 1966 1972 excerpt

incidence and impact the regional variation of poverty effects due to fossil fuel subsidy reform since fossil fuel subsidy reforms can induce significant distributional shifts and price shocks effective compensation and social protection programs are crucial based on the statistical simulation model by araar and verme 2012 this study estimates the regional variability of direct welfare effects of removing fuel subsidies in nigeria uncompensated subsidy removal is estimated to increase the national poverty rate by 3 4 on average however uniform cash compensation that appears effective at the national average is found to fail to mitigate price shocks in 16 of 37 states thus putting livelihoods and public support for reforms at risk states that are estimated to incur the largest welfare shocks coincide with hotspots of civil unrest following nigeria s 2012 subsidy reform attempt the study illustrates how regionally disaggregated compensation can be revenue neutral and maintain or reduce pre reform poverty rates in all states overall it highlights the importance of understanding differences in vulnerability and designing tailored social protection schemes which ensure public support for subsidy reforms

carbon tax incidence on household demand effects on welfare income inequality and poverty incidence in thailand abstract studying the impact of a carbon tax on household demand can be relevant in terms of securing public acceptance of a carbon tax and clarifying the implications for policy design this paper aims to fill a gap in the academic literature by simulating carbon tax scenarios and estimating distributional effects of the tax on household welfare income inequality and poverty rates based on household consumption in thailand the study employs a microsimulation model incorporating the economy wide effects of the tax on prices and consumers behavioral responses to changes in prices the results indicate that a carbon tax is progressive in thailand under revenue recycling scenarios by expanding social transfer programs when carbon tax revenues are recycled through pensions for elderly people the carbon tax could reduce the poverty rate and improve the welfare of households in the lowest quintile the results imply that the distributional impacts of environmental taxes could result in favorable outcomes for income inequality and poverty reduction in developing countries

economic policy uncertainty and risk spillovers in the eurozone this paper focuses on the impact of economic policy uncertainty on risk spillovers within the eurozone and contributes to these two growing literatures to this end we adapt the two step procedure developed by adrian and brunnermeier forthcoming in the framework of financial systemic risk to the sovereign bond market accordingly we attempt i to measure the extent to which distress affecting one given country s sovereign spreads can affect the eurozone s bond market as a whole and then ii to identify the determinants of risk spillovers by estimating a panel data model with macroeconomic state variables and economic policy uncertainty epu indices introduced by baker et al 2013 as regressors epu indices considered concern the four largest eurozone countries i e germany france italy and spain as well as the united states the model is estimated with quarterly data for ten countries representing the bulk of debt issuances within the eurozone over a period ranging from q4 2008 to q2 2013 which is characterized by historically high dispersion of sovereign bond spreads either across time or across countries our results support the idea that economic policy uncertainty in the core economies of the eurozone i e germany and france as well as in the largest periphery countries i e italy and spain can create an environment likely to exacerbate the transmission of risk arising from abnormal developments of individual countries sovereign spreads to the eurozone bond market as a whole in this respect our results plead for larger effort of eurozone leaders to reduce the uncertainty surrounding their economic policy in periods of crisis not only to avoid adverse effects on their own economies but also to reduce the risk of a destabilization of the eurozone sovereign bond market as a whole

external public debt trade linkages and contagion during the eurozone crisis against the backdrop of the contagion literature the paper analyses the impact of financial and trade linkages on sovereign bond spreads in the eurozone crisis using quarterly data for a sample of emu countries during the period 2000 13 we estimate fixed effect panel models with driscoll and kraay standard errors that are robust to general forms of spatial and temporal dependence our main results can be summarised as follows first we suggest that the sudden stop of capital inflow towards the peripheral sovereign debt triggered a re segmentation of financial markets and economic systems along national borders with negative implications for risk sharing and the efficient allocation of capital the home bias effect that is the increase in the share of sovereign debt held by domestic banks worsened the country specific risk because the twin crisis sovereign and banking began to be conceived as more closely intertwined within countries than before second the structure of international trade helps to account for the geographic scope of contagion even after controlling for macroeconomic and fiscal vulnerabilities finally the substitution effect of public debt securities of stand alone emerging countries has affected more the sovereign spreads in the core than in the periphery

oil and the macroeconomy since the 1970s economists have long been intrigued by empirical evidence that suggests that oil price shocks may be closely related to macroeconomic performance this interest dates back to the 1970s the 1970s were a period of growing dependence on imported oil unprecedented disruptions in the global oil market and poor macroeconomic performance in the united states thus it was natural to suspect a causal relationship from oil prices to u s macroeconomic aggregates since then a large body of work has accumulated that purports to establish this link on theoretical grounds and to provide empirical evidence in its support we do not attempt a comprehensive survey of this literature but rather provide an idiosyncratic synthesis of what we view as the key issues in this debate and the insights gained over the last 30 years the timing seems right for such an account although the experience of the 1970s continues to play an important role in discussions of the link between oil and the macroeconomy there have been a number of new oil price shocks since the 1970s notably the 1986 collapse of oil prices and the 2000 boom in oil prices as well as the oil price increases associated with the 1990 1991 gulf war and the 2003 iraq war given this richer case history we are arguably in a better position than two decades ago to distinguish the idiosyncratic features of each oil crisis from the systematic effects increases in oil prices have been held responsible for recessions periods of excessive inflation reduced productivity and lower economic growth in this paper we review the arguments supporting such views first we highlight some of the conceptual difficulties in assigning a central role to oil price shocks in explaining

recent drivers of the real oil price revisiting and extending kilian s 2009 findings abstract we replicate and update the results of kilian 2009 to include the period since the financial crisis we separate the drivers of the price of crude oil shocks into three components oil supply shocks aggregate demand shocks and oil market specific demand shocks we provide evidence that the run up of oil prices in 2008 was mostly driven by aggregate demand shocks and to a lesser extend by oil market specific demand shocks complementing similar analyses in baumeister and kilian 2016a and kilian 2017 our results confirm that the cumulative effect of aggregate demand disruptions on the price of crude oil started before 2007 furthermore aggregate demand shocks and oil market specific demand shocks rather than oil supply shocks have the most significant effects on u s output and prices the findings are robust to an alternative measure of global real economic activity

how does liquidity affect government bond yields the paper explores the determinants of yield differentials between sovereign bonds using euro area data there is a common trend in yield differentials which is correlated with a measure of aggregate risk in contrast liquidity differentials display sizeable heterogeneity and no common factor we propose a simple model with endogenous liquidity demand where a bond s liquidity premium depends both on its transaction cost and on investment opportunities the model predicts that yield differentials should increase in both liquidity and risk with an interaction term of the opposite sign testing these predictions on daily data we find that the aggregate risk factor is consistently priced liquidity differentials are priced for a subset of countries and their interaction with the risk factor is in line with the model s prediction and crucial to detect their effect

trends in income and price elasticities of transport demand 1850 2010 the purpose of this paper is to estimate trends in income and price elasticities and to offer insights for the future growth in transport use with particular emphasis on the impact of energy and technological transitions the results indicate that income and price elasticities of passenger transport demand in the united kingdom were very large 3 1 and 1 5 respectively in the mid nineteenth century and declined since then in 2010 long run income and price elasticity of aggregate land transport demand were estimated to be 0 8 and 0 6 these trends suggest that future elasticities related to transport demand in developed economies may decline very gradually and in developing economies where elasticities are often larger they will probably decline more rapidly as the economies develop because of the declining trends in elasticities future energy and technological transitions are not likely to generate the growth rates in energy consumption that occurred following transitions in the nineteenth century nevertheless energy and technological transitions such as the car and the airplane appear to have delayed and probably will delay declining trends in income and price elasticity of aggregate land transport demand

are co2 taxes regressive evidence from the danish experience abstract denmark today carries one of the heaviest environmental tax burdens in the world bringing in around 10 of public revenues while evaluations have shown that the danish co 2 and other environmental taxes work as an effective measure to reduce emissions a considerable barrier to increased use of these instruments today seems to be a widespread perception of their socially adverse effects in this article it is demonstrated that co 2 taxes imposed on energy consumption in households as well as in industry do in fact tend to be regressive and therefore have undesirable distributional effects this holds especially for taxes imposed directly on households to analyze this we apply national consumer survey statistics in combination with input output tables

distributional effects of subsidy removal and implementation of carbon taxes in mexican households abstract this paper presents a microsimulation using data from the national households income and expenditure survey nhies from 1994 to 2010 to determine the distributional effects of the price changes arising from energy and environmental policies and their impact on mexican households we reported simulations of several changes in energy prices as a result of partial or total energy subsidy removal including carbon tax in order to examine whether the subsidy mechanism and carbon tax tend to be progressive or regressive we evaluated the households burden in different income levels these simulations respond to the need for an assessment of economic and environmental impacts of energy subsidies in mexico this is of great importance for mexico because of effort that has been taken in the development of energy policies and the rising interest of the mexican government in mitigating carbon dioxide co2 emissions and their concomitant environmental damage

the effects of the energy price reform on households consumption in iran abstract the substantial subsidizing of energy prices over the years has led to high energy consumption inefficiencies fiscal pressures and environmental problems in iran to address the increasing socio economic problems associated with the energy subsidies the government embarked on an aggressive energy price reform through which energy subsidies were removed and cash handouts were given to all households in 2010 in this paper i analyze the effectiveness of the energy price reform in iran by estimating energy demand elasticities for households in different income groups i apply a two stage consumer optimization model and estimate the system of energy expenditures shares using the household budget survey data for the period 2001 2008 the results show that the overall price elasticities of demand are small but income elasticities are close to one the results also indicate heterogeneous responses to energy price and income changes in different income groups specifically the urban households show stronger response to price changes but rural households particularly mid income households to income changes these findings suggest that the current policy of price increases would not solely be able to reduce energy consumption and therefore it should be geared towards increasing energy efficiency through a series of price and non price measures

stock index futures does the tail wag the dog the increase in program trading based on a comparatively narrow blue chip stock market barometer the major market index mmi is said to be fueling volatile price swings in the stock market a case of the tail wagging the dog the mmi is a price weighted index of 20 very actively traded stocks 16 of which are included in the dow jones 30 industrials because of its relatively small size the mmi is expected to be more easily arbitragible than other stock index futures contracts basically program trading involves taking a position long or short in a portfolio of stocks comprising the index and simultaneously taking an opposite position in the index futures contracts the objective of the program trade is to create a risk free position that earns a return in excess of the currently available risk free return program trades may move both the futures and the spot market the chain of causality may work as follows 1 investors believe the stock market will rise and they purchase futures contracts in expectation of higher equity values the purchase of the contracts is preferable to the purchase of the underlying stocks because it entails no initial investment and lower transaction costs 2 the rise in futures prices causes an imbalance between the prices of the futures and the underlying index as this premium between futures and index increases it may become profitable to execute a program trade 3 the simultaneous sale of futures and purchase of the underlying index will cause the premium between the futures and index to shrink changes in factors such as interest rates can also affect the equilibrium relation between the index price and the futures price thereby changing the premium or discount between the two markets program traders can take advantage of any change in the spread between the markets it does not matter what causes the change in spreads whether internal factors such as changes in investor expectations or external factors such as interest rate changes all program trading does is to bring cash and futures prices together the program trade may be an essential mechanism that ensures that futures prices and underlying equity prices are efficiently determined and that the hedging effectiveness of the futures contracts is reliable to date most of the literature on the impact of futures trading on the cash market has focused on changes in spot price volatility because of the initiation or cessation of futures trading a common conclusion of these studies is that the futures market has a smoothing effect on the cash market stabilizing the spot price the recent uproar engendered by the triple witching hour and the so called crises at expiration brings into question the smoothing influence that futures have on the underlying index 2 if the market is efficient prices adjust instantaneously to reflect all relevant information and knowledge of such information cannot lead to excess risk adjusted returns the central concept in the efficient market hypothesis is the fair game model 3 a sequence of past returns over time is a fair game if today s price reflects the then available information making it impossible to earn excess risk adjusted returns by trading on that information if the information set today contains all the information known and used by the market participants in the spot market in determining the spot price one of the components of the information set is the previous change in the price of futures contracts 4 does the tail wag the dog the financial press and the sec have answered this question in the affirmative 5 this note investigates the impact of the futures market on the spot market by evaluating the relation between index futures price changes and subsequent spot index price changes in addition we evaluate the degree to which the expiration of the futures contract affects the underlying index

distributional effects of carbon taxes the case of mexico abstract in this study i develop an analytical general equilibrium model to assess the distributional effects across income groups of a carbon tax assuming that the revenue from the carbon tax is recycled in two different ways as a manufacturing tax cut and a food subsidy i use this analytical model to provide intuition about the main distributional components the model is calibrated with data from mexico to obtain unambiguous price and quantity changes i find that the distribution of the costs is driven by the way the revenue is recycled in particular the costs are distributed regressively when the revenue is recycled as a manufacturing tax cut and progressively when it is recycled as a food subsidy providing a food subsidy also generates higher welfare and lower carbon emissions than the manufacturing tax cut to compare and test the robustness of the numerical findings for mexico i calibrate the model with data for a developed country specifically the u s a despite differences in the magnitude of the changes in some variables the general findings mentioned above also hold for u s a data these results suggest that as found for the u s a in recent studies carbon taxes are not necessarily regressive rather the way revenue is recycled is a major determinant of how the carbon tax costs are distributed

poverty and distributional effects of carbon pricing in low and middle income countries a global comparative analysis abstract even though concerns about adverse distributional implications for the poor are one of the most important political challenges for carbon pricing the existing literature reveals ambiguous results for this reason we assess the expected incidence of moderate carbon price increases for different income groups in 87 mostly low and middle income countries building on a consistent dataset and method we find that for countries with per capita incomes of below usd 15 000 per year at ppp adjusted 2011 usd carbon pricing has on average progressive distributional effects we also develop a novel decomposition technique to show that distributional outcomes are primarily determined by differences among income groups in consumption patterns of energy rather than of food goods or services we argue that an inverse u shape relationship between energy expenditure shares and income explains why carbon pricing tends to be regressive in countries with relatively higher income since these countries are likely to have more financial resources and institutional capacities to deal with distributional issues our findings suggest that mitigating climate change raising domestic revenue and reducing economic inequality are not mutually exclusive even in low and middle income countries

the distributional implications of a carbon tax in ireland we study the effects of carbon tax and revenue recycling across the income distribution in the republic of ireland in absolute terms a carbon tax of 20 tco2 would cost the poorest households less than 3 week and the richest households more than 4 week a carbon tax is regressive therefore however if the tax revenue is used to increase social benefits and tax credits households across the income distribution can be made better off without exhausting the total carbon tax revenue

the european sovereign debt crisis the origin and propagation of the european sovereign debt crisis can be attributed to the flawed original design of the euro in particular there was an incomplete understanding of the fragility of a monetary union under crisis conditions especially in the absence of banking union and other european level buffer mechanisms moreover the inherent messiness involved in proposing and implementing incremental multicountry crisis management responses on the fly has been an important destabilizing factor throughout the crisis after diagnosing the situation we consider reforms that might improve the resilience of the euro area to future fiscal shocks

time and frequency connectedness among oil shocks electricity and clean energy markets abstract this paper examines the time and frequency connectedness among electricity carbon and clean energy markets and oil price demand and supply shocks in doing so we use the spillover method proposed by diebold and yilmaz 2012 and its extension in the frequency domain by barunik and k ehlik 2018 we find increased connectedness during the global financial crisis as well as in the shale oil revolution period the total connectedness is also higher in the short run compared to the long run due to their low connectedness electricity futures can act as a risk diversifier and safe haven asset against oil shocks net pairwise directional connectedness among oil shocks and the clean energy index is higher during the shale oil revolution these results have important implications for investors with different investment time horizons

oil demand shocks reconsidered a cointegrated vector autoregression abstract we reconsider the conclusions about the importance of oil demand shocks and the unimportance of supply shocks reported by kilian 2009 we investigate whether the proxy for worldwide real economic activity dry bulk maritime freight costs represents anything more than transportation costs by analyzing the relation between these costs and oil prices the meaning of this variable is critical because transportation costs appear on both sides of the equations estimated by kilian directly as dry bulk maritime freight costs and as part of the measure for oil prices we also investigate the effects of representing oil supply with an aggregate of opec and non opec production because they likely use different criteria to chose output finally we investigate kilian s use of the first difference of supply while the other variables in his model are represented as levels the results suggest that opec and nonopec nations use different criteria to set output and that reductions increases in opec production raise lower oil prices the elements of the cointegrating relations their loadings and impulse response functions suggest that the positive relation between dry bulk maritime freight costs and oil prices simply represents the effect of higher oil prices on transportation costs sensitivity analyses suggest that these differences are caused by including transportation costs in the measure of oil prices aggregating opec and non opec productions and using a very long lag length to estimate the var together these results suggest that conclusions about the importance of demand shocks and the unimportance of supply shocks are not robust to alternative specifications that are consistent with many empirical findings about the world oil market

u s equity and commodity futures markets hedging or financialization abstract in this paper we investigate the hedging versus the financialization nature of commodity futures vis a vis the equity market using a arma filter based correlation approach our results suggest that while gold futures are typically seen as a hedge against unfavorable fluctuations in the stock market the majority of commodity futures appears to be treated as a separate asset class in line with their increasing financialization our results are robust to the presence of inflation highlight the hedging role played by fuel energy commodity futures in the nineties and reveal that the commodity financialization boosted since the 2000s we also show that gold futures are partially a safe haven for equity investments in the short term but not in the mid term finally we uncover some hedging financialization of crude oil futures associated to global demand oil supply shocks

carbon taxation prices and welfare in new zealand abstract this paper examines the effects on consumer prices arising from imposing a carbon tax in new zealand using information about inter industry transactions and the use of fossil fuels by industries the welfare effects of the carbon tax are examined for a range of different household types finally overall measures of inequality are reported

the october 1987 s p 500 stock futures basis five minute changes in the s p 500 index and futures contract are examined over a ten day period surrounding the october 1987 stock market crash since nonsynchronous trading problems are severe in these data new index estimators are derived and used the estimators use the complete transaction history of all 500 stocks nonsynchronous trading explains part of the large absolute futures cash basis observed during the crash the remainder may be due to disintegration of the two markets even after adjustment for nonsynchronous trading the index displays more autocorrelation than does the futures and the futures leads the index

distributional effects of a carbon tax on chinese households a case of shanghai abstract as an effective policy instrument to reduce co 2 emissions the effects of a carbon tax on distribution have been the critical factor in determining whether a carbon tax will be acceptable in china taking shanghai as an example which is the economic center and front runner of china this paper estimates the distributional effect of a carbon tax on households in various income groups by using the input output model and the suits index the results indicate that the comprehensive distributional effect of the carbon tax is regressive the expenditure of the low income group caused by the carbon tax accounts for 0 853 of the total expenditure while that of the high income group 0 712 the direct distributional effect presents a weak progressivity while the indirect one is significantly regressive and the latter is much larger than the former moreover the suits index of the carbon tax is 0 078 implying that the carbon tax burden on the low income group is the highest and thus that a carbon tax can intensify income inequality therefore when introducing a carbon tax some rational associated redistribution or compensation measures such as purposive transfer payments should be implemented to restrict or even eliminate the regressivity of the carbon tax

measuring bilateral spillover and testing contagion on sovereign bond markets in europe abstract the global financial crisis rapidly spread across borders and financial markets and also distressed eu bond markets the crisis did not hit all markets in the same way we measure the strength and direction of linkages between 16 eu sovereign bond markets using a factor augmented version of the var model in diebold and yilmaz 2009 we then provide a novel test for contagion by applying the multivariate structural break test of qu and perron 2007 on this favar detecting significant sudden changes in shock transmission results indicate substantial spillover especially between emu countries with belgium italy and spain being key markets during the financial crisis contagion has been a rather rare phenomenon limited to a few well defined moments of uncertainty on financial assistance packages for greece ireland and portugal most of the frequent surges in market co movement are driven by larger shocks rather than by contagion

income elasticity of gasoline demand a meta analysis abstract in this paper we quantitatively synthesize empirical estimates of the income elasticity of gasoline demand reported in previous studies the studies cover many countries and report a mean elasticity of 0 28 for the short run and 0 66 for the long run we show however that these mean estimates are biased upwards because of publication bias the tendency to suppress negative and insignificant estimates of the elasticity we employ mixed effects multilevel meta regression to filter out publication bias from the literature our results suggest that the income elasticity of gasoline demand is on average much smaller than reported in previous surveys the mean corrected for publication bias is 0 1 for the short run and 0 23 for the long run

common nonstationary components of asset prices abstract portfolio separation in a multi period general equilibrium context implies that asset prices are collinear in economies that do not exhibit separation but that move close to separation approximate collinearity or cointegration emerges as a statistical model of actual data a new test for cointegration is proposed it is based on time series canonical correlation analysis and solves the problem of unidentified parameters under the null hypothesis and of identification of the cointegrating vectors when more than two time series are investigated an empirical analysis of prices of five size based portfolios and five industry based portfolios of common stock reveals substantial evidence of cointegration

china s income gap and inequality under clean energy transformation a cge model assessment abstract to achieve nationally determined contribution ndc targets china has developed a series of low carbon development plans among them the clean energy transformation is very crucial this study evaluates the impact of a set of policies including the development of renewable energy upgrading heavy industry and energy efficiency improvement on china s income gap between 2012 and 2050 a dynamic computable general equilibrium cge model with detailed representations of economic activity an upgraded labor market and disaggregated labor types based on statistical and survey data is used our research provides support for the necessity of low carbon policies to achieve ndc targets results show some key findings first low carbon policies have the greatest impact on employment across all energy industries with negative impacts in most traditional energy sectors and positive impacts in most renewable power sectors second labor will continue to migrate from rural to urban areas with the transformation of the economic structure and the urbanization rate will further increase reaching a maximum of around 70 the reduction of the rural population will bring new opportunities for the modernization of agriculture increasing the income of rural residents and realizing the equitable development between urban and rural areas third the income gap among urban residents will widen due to the different level of labor demand for employees with different education levels

taxation of multiple greenhouse gases and the effects on income distribution a case study of the netherlands current economic instruments aimed at climate change mitigation focus on co2 emissions only but the kyoto protocol refers to other greenhouse gases ghg as well as co2 these are ch4 n2o hfcs pfcs and sf6 taxation of multiple greenhouse gases improves the cost effectiveness of climate change mitigation it is not yet clear however what the effect is of multigas taxation on the distribution of the tax burden across income groups this paper examines and compares distributional effects of a co2 tax and a comprehensive tax that covers all six ghg of the kyoto protocol the study concentrates on the netherlands in the year 2000 we established tax rates on the basis of marginal abatement cost curves and the dutch policy target the distributional effects have been determined by means of environmentally extended input output analysis and data on consumer expenditures our results show that taxation of multiple ghg improves not only the cost effectiveness of climate change mitigation but also distributes the tax burden more equally across income groups as compared to a co2 tax these findings are relevant for the debate on the role of non co2 ghg in climate change mitigation

the welfare effects and the distributive impact of carbon taxation on italian households in this work the welfare effects and the distributive impact on italian households of the italian carbon tax are calculated the carbon tax has been introduced in italy at the beginning of 1999 asking for smooth increases over a number of years in the prices of most fossil fuels its welfare effects have been calculated using true cost of living index numbers and the compensating variation the parameters have been obtained through estimation of a complete almost ideal demand system using households data from 1985 to 1996 the welfare loss turns out to be quite substantial and affects italian households in a non negligible way but the distribution of welfare losses across different levels of total monthly expenditures does not allow sustaining the regressivity of carbon taxation as the effect becomes bigger as we move up the income distribution this evidence might encourage the use of carbon taxes at least in the transport sector as cost effective instruments of environmental policy especially after the ratification of the kyoto protocol on climate change

granger causality in peripheral emu public debt markets a dynamic approach our research aims to analyze the possible existence of granger causal relationships in the behavior of public debt issued by peripheral member countries of the european economic and monetary union emu with special emphasis on the recent episodes of crisis triggered in the eurozone sovereign debt markets since 2009 with this goal in mind we make use of a database of daily frequency of yields on 10 year government bonds issued by five emu countries greece ireland italy portugal and spain covering the entire history of the emu from its inception on 1 january 1999 until 31 december 2010 in the first step we explore the pair wise granger causal relationship between yields both for the whole sample and for changing subsamples of the data in order to capture the possible time varying causal relationship this approach allows us to detect episodes of significant increase in granger causality between yields on bonds issued by different countries in the second step we study the determinants of these episodes analyzing the role played by different factors paying special attention to instruments that capture the total national debt domestic and foreign in each country

heterogeneity of the determinants of euro area sovereign bond spreads what does it tell us about financial stability abstract in this paper we assess the movements of euro area sovereign bond yield spreads vis a vis the german bund as processes specified across different levels of volatility and subject to movements in asset prices and economic conditions the determinants we use are grouped into domestic and euro area aggregates thus allowing us to derive results on their relative explanatory power and compare them across time and the spectrum of countries we find that volatility influences the deterministic processes of the euro area sovereign spreads and that identical determinants have effects on spreads that vary considerably across countries furthermore we find that variables reflecting investment confidence conditions and perceptions for the upcoming economic activity are significant determinants and their significance remains to a large extent even when controlling for fiscal variables

intraday price change and trading volume relations in the stock and stock option markets this study investigates intraday relations between price changes and trading volume of options and stocks for a sample of firms whose options traded on the cboe during the first quarter of 1986 after purging the price change series of the effects of bid ask spreads multivariate time series analysis is used to estimate the lead lag relation between the price changes in the option and stock markets the results indicate that price changes in the stock market lead the option market by as much as fifteen minutes the analysis of trading volume indicates that the stock market lead may be even longer the intense trading activity in and in fact the very existence of organized stock option markets attest to the economic benefits that these financial contracts provide reduced transaction costs and increased financial leverage are two reasons why trading in the stock option market may be more attractive than trading in the market for the underlying stock in addition these cheaper and more flexible trading opportunities attract new and differently informed investors to the marketplace the resulting increase in trading activity together with the inextricable arbitrage linkage between stock and option prices imply an increase in market efficiency this study investigates empirically the intraday price change and trading volume relations between stocks and options for a sample of firms whose options were actively traded on the chicago board options exchange during the first quarter of 1986 in particular intraday call option price changes are translated into implied stock price changes using the american call option pricing model these intraday implied stock price changes are then compared with the actual stock price changes to identify which if either market leads the other in perfectly functioning capital markets there should be complete simultaneity between the series that is new information disseminating into the marketplace should be reflected in the prices and the trading activity of both securities simultaneously institutional factors however may make the stock option market more attractive to information traders this may cause price changes and trading activity due to new information to be observed in the option market first followed by price

determinants of sovereign bond yield spreads in the emu an optimal currency area perspective in the light of the recent financial crisis we take a panel cointegration approach that allows for structural breaks to the analysis of the determinants of sovereign bond yield spreads in nine economies of the european monetary union we find evidence for a level break in the cointegrating relationship moreover results show that i fiscal imbalances namely expected government debt to gdp differentials are the main long run drivers of sovereign spreads ii liquidity risks and cumulated inflation differentials have non negligible weights but iii all conclusions are ultimately connected to whether or not the sample of countries is composed of members of an optimal currency area oca in particular we establish i that results are overall driven by those countries not passing the oca test and ii that investors closely monitor and severely punish the deterioration of expected debt positions of those economies exhibiting significant gaps in competitiveness

quadratic engel curves and consumer demand this paper presents a model of consumer demand that is consistent with the observed expenditure patterns of individual consumers in a long time series of expenditure surveys and is also able to provide a detailed welfare analysis of shifts in relative prices a nonparametric analysis of consumer expenditure patterns suggests that engel curves require quadratic terms in the logarithm of expenditure while popular models of demand such as the translog or the almost ideal demand systems do allow flexible price responses within a theoretically coherent structure they have expenditure share engel curves that are linear in the logarithm of total expenditure we derive the complete class of integrable quadratic logarithmic expenditure share systems a specification from this class is estimated on a large pooled data set of u k households models that fail to account for engel curvature are found ro generate important distortions in the patterns of welfare losses associated with a tax increase

an analysis of the economic justification for consolidation in a secondary security market abstract this paper considers whether all trading in a listed security should be required to go through an exchange to this end the incentives for a brokerage firm to offer in house execution services are discussed and an analytical framework is developed which shows that under idealized conditions fragmentation of the market through in house execution services would not result in any overall deterioration of market performance characteristics however when some of the idealized conditions are relaxed the market fragmentation arising from in house execution causes the gains to some customers to be more than overcome by the losses to others the analysis which also takes account of the desirability of enforcing reasonable trading priority rules such as priority by price and time across all traders yields several public policy implications for some unlikely scenarios it would be possible through appropriate commission sharing and a perfectly operating intermarket trading system for optimal overall market performance to be consistent with the market fragmentation inherent in in house execution services however for most realistic scenarios fragmentation would cause a deterioration in the quality of the market thus it seems desirable to require that all trading go through a central exchange with a consolidated limit order book

price and income elasticities of residential energy demand in germany we apply a quadratic expenditure system to estimate price and expenditure elasticities of residential energy demand electricity and heating in germany using official expenditure data from 1993 to 2008 we estimate an expenditure elasticity for electricity of 0 3988 and of 0 4055 for space heating the own price elasticity for electricity is 0 4310 and 0 5008 in the case of space heating disaggregation of households by expenditure and demographic composition reveals that the behavioural response to energy price changes is weaker stronger for low income top income households there are considerable economies of scale in residential energy use but scale effects are not well approximated by the new oedc equivalence scale real increases in energy prices show a regressive pattern of incidence implying that the welfare consequences of direct energy taxation are larger for low income households the application of zero elasticities in assessments of welfare consequences of energy taxation strongly underestimates potential welfare effects the increase in inequality is 22 smaller when compared to the application of rich and disaggregated behavioural response patterns as estimated in this paper
