a simplified jump process for common stock returns the specification of a statistical distribution which accurately models the behavior of stock returns continues to be a salient issue in financial economics with the introduction of arithmetic and geometric brownian motion models much attention has recently focused on a poisson mixture of distributions as an appropriate specification of stock returns for example see 12 3 8 10 5 and 1 consistent with empirical evidence these models yield leptokurtic security return distributions and furthermore the specification has much economic intuition in particular one may always decompose the total change in stock price into normal and abnormal components the normal change may be due to variation in capitalization rates a temporary imbalance between supply and demand or the receipt of any other information which causes marginal price changes this component is modelled as a lognormal diffusion process the abnormal change is due to the receipt of any information which causes a more than marginal change in the price of the stock and is usually modeled as a poisson process

the message in weekly exchange rates in the european monetary system mean reversion conditional heteroscedasticity and jumps weekly rates of the european monetary system ems vis a vis the deutsche mark from april 1979 to march 1991 are modeled as a combined ma 1 garch 1 1 jump process the moving average ma part accounts for mean reversion required for the rates to stay inside the target zone the generalized autoregressive conditional heteroscedasticity garch part accounts for changing volatility whereas the jump process models parity changes and other erratic movements using an adjusted pearson chi squared goodness of fit test we find similar results for the bernoulli and the poisson jump processes in those cases in which the bernoulli normal distribution does not pass the goodness of fit test a mixture of three normals does finally the ma 1 garch 1 1 bernoulli jump models are jointly estimated assuming a constant contemporaneous correlation matrix for the disturbances and a common jump probability for all the currencies

what will consumers pay for social product features the importance of ethical consumerism to many companies worldwide has increased dramatically in recent years ethical consumerism encompasses the importance of non traditional and social components of a company s products and business process to strategic success such as environmental protectionism child labor practices and so on the present paper utilizes a random utility theoretic experimental design to provide estimates of the relative value selected consumers place on the social features of products

the amenity value of the british climate this study explores the amenity value of climate to households in britain we employ the hedonic technique and use household panel data to derive the marginal willingness to pay for small changes in climate variables we analyse both the housing and the labour market climate is described in terms of heating cooling degree and rain days evidence suggests that it is the housing market that mainly compensates for climate amenities according to the results the relationship between property prices and climate has an inverted u shape for the sample about 50 per cent of the locations are close to the preferred levels of heating and cooling degree days while the results for rain days are more varied connecting the results to projections of climate change leads to the conclusion that future developments are likely to move a number of households further away from their preferred climate thus leading to larger regional disparities

rebuilding trust ireland s csr plan in the light of caritas in veritate this paper seeks to contribute to the discussion on national corporate social responsibility csr plans from the perspectives of the three logics as articulated in caritas in veritate by using the irish national csr plan as an example good for business good for the community ireland s national plan on corporate social responsibility 2014 2016 maintains that csr activities can enable organisations to build relationships and trust with communities one of the consequences of the 2008 financial crisis was the decrease in trust in banking systems and in business more broadly it is well recognised that relationships of trust are essential to the life of the market the state and civil society pope emeritus benedict xvi s caritas in veritate contends that corresponding to the life of the market the state and civil society are three logics the logic of exchange i e giving to acquire the logic of public obligation i e giving through duty and the logic of gift i e giving due to solidarity this paper proposes that the normative framework of the three logics of caritas in veritate can be read into the irish national csr plan this paper argues that the examples of csr initiatives proffered by the plan could point organisations in the direction of the logic of gift and therefore enable the rebuilding of relationships of trust with citizens and communities

voluntary disclosure of greenhouse gas emissions contrasting the carbon disclosure project and corporate reports as global warming continues to attract growing levels of attention various stakeholders states general public investors and lobbyists have put climate change on corporate agendas and expect firms to disclose relevant greenhouse gas ghg information in this paper we investigate the consistency of the ghg information voluntarily disclosed by french listed firms through two different communication channels corporate reports cr and the carbon disclosure project cdp more precisely we contrast the amounts of ghg emissions reported and the methodological explanations provided named traceability in each channel consistent with a stakeholder theory perspective we find that ghg amounts are significantly lower in the cr than in the cdp we also find that firms increase the cr figures traceability when there is a discrepancy between disclosures in the two channels we suggest that the aim of this greater traceability is to enhance information credibility across the different channels used

normal mixture diffusion with uncertain volatility modelling short and long term smile effects this paper introduces a parameterization of the normal mixture diffusion nmd local volatility model that captures only a short term smile effect and then extends the model so that it also captures a long term smile effect we focus on the binomial nmd parameterization so called because it is based on simple and intuitive assumptions that imply the mixing law for the normal mixture log price density is binomial with more than two possible states for volatility the general parameterization is related to the multinomial mixing law in this parsimonious class of complete market models option pricing and hedging is straightforward since model prices and deltas are simple weighted averages of black scholes prices and deltas but they only capture a short term smile effect where leptokurtosis in the log price density decreases with term in accordance with the stylised facts of econometric analysis on ex post returns of different frequencies and the central limit theorem however the last part of the paper shows that longer term smile effects that arise from uncertainty in the local volatility surface can be modeled by a natural extension of the binomial nmd parameterization results are illustrated by calibrating the model to several euro us dollar currency option smile surfaces

an econometric analysis of emission allowance prices knowledge of the statistical distribution of the prices of emission allowances and their forecastability are crucial in constructing among other things purchasing and risk management strategies in the emissions constrained markets this paper analyzes the two emission permits markets co2 in europe and so2 in the us and investigates a model for dealing with the unique stylized facts of this type of data its effectiveness in terms of model fit and out of sample value at risk forecasting as compared to models commonly used in risk forecasting contexts is demonstrated

the effectiveness of the public support policies for the european industry financing as a contribution to sustainable development in recent years the debate about the role of the public institutions in the fields of corporate social responsibility and sustainable development has gained momentum nevertheless the ambiguity of the latter concepts makes it difficult both to measure them and to estimate the impact that the different public initiatives may have on them in this sense the present research has the aim to design a fuzzy logic based methodology applied to the evaluation of the above mentioned processes in relation to the state aid policies for the european industry regarding the study contour the european union state aids seems not to have introduced important changes leading to socially responsible results and therefore favourable for the sustainable development generated by the european manufacturing industry

price drivers and structural breaks in european carbon prices 2005 2007 this article aims at characterizing the daily price fundamentals of european union allowances euas traded since 2005 as part of the emissions trading scheme ets the presence of two structural changes on april 2006 following the disclosure of 2005 verified emissions and on october 2006 following the european commission announcement of stricter phase ii allocation allows to isolate distinct fundamentals evolving overtime the results extend previous literature by showing that eua spot prices react not only to energy prices with forecast errors but also to unanticipated temperatures changes during colder events besides the sub period decomposition of the pilot phase gives a better grasp of institutional and market events that drive allowance price changes

corporate social and financial performance an investigation in the u k supermarket industry the comparison of corporate social performance with corporate financial performance has been a popular field of study over the past 25 years the results while broadly conclusive of a positive relationship are not entirely consistent in addition most of the previous studies have concentrated on large scale cross industry studies and often with a single variable for corporate social performance in order to produce statistically significant results this weakens the richness of understanding that might be obtained from a single industry study with multiple social variables which would also allow investigation of inter relationships between individual and sub sets of social performance measures and between individual and sub sets of social performance and financial performance measures there have also been criticisms that the results lack a rigorous theoretical basis and the paper demonstrates clearly how stakeholder theory must form the basis for this area of research following a review of the literature this paper presents the initial findings from a study of the u k supermarket industry which suggest that contemporaneous social and financial performance are negatively related while prior period financial performance is positively related with subsequent social performance positive relationships between both age and size of the company with social performance are also found

new estimates of climate demand evidence from location choice abstract we develop and apply to census data a new method for estimating climate demand the method is useful for ranking quality of life based upon a willingness to pay criterion our two major findings are that the willingness to pay quality of life index is correlated with the hedonic approach s ranking but that the migration approach generates much larger estimates of willingness to pay for a more moderate climate this finding is relevant for evaluating the economic impact of global warming

is bitcoin a commodity on price jumps demand shocks and certainty of supply abstract this paper discusses how similar bitcoin is to a commodity the application of a number of both linear and non linear garch models indicates that the role of extreme price movements is particularly pronounced garch models with student t innovations as well as combined jump garch models are among the models with the best fit the role of large movements is found to be stronger in the bitcoin market than in the markets for crude oil and gold as bitcoin shares with these exhaustible resource commodities characteristics such as the fixed supply the analysis of bitcoin prices can generally learn from the analysis of exhaustible resource commodities however whereas the short run supply of gold and oil are uncertain there are no uncertainties on the bitcoin supply side thus the observed movements of bitcoin prices can be interpreted as results of bitcoin demand shocks

multiple bubbles in the european union emission trading scheme abstract the european union emission trading scheme eu ets is the first large scale co 2 emission trading system in the world carbon allowances are financial assets potentially vulnerable to the behavior of traders and investors in fact the carbon price has been quite volatile since the inception of the market and it has recently hit very low values however to date no work exists to evaluate whether volatility and price spikes are due to episodes of speculation and price bubbles our paper fills this gap we use the recent approaches developed by phillips and yu 2010 phillips et al 2011 and phillips et al 2015a 2015b who propose a recursive right sided unit root approaches to detect and date stamp mildly explosive behaviors and carbon market exuberance we complement this methodology by using the wild bootstrap procedure by goncalves and kilian 2004 to control for the heteroschedasticity of carbon price data analyzing the eu ets front month contract price from 2005 to 2014 we find different episodes of price bubbles these episodes are not explained by similar behavior of the fundamentals but seem related to energy and environmental policy announcements our results can provide insightful policy implications in the context of the actual carbon market reform as well as the implementation of stricter financial regulations rules to co 2 trading

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

new estimates of quality of life in urban areas implicit markets capture compensation for intraurban and interregional differe nces in amenities and yield differences in housing prices and wages these pecuniary differences become preference based weights in a qual ity of life index hedonic equations are estimated using microdata fr om the 1980 census and assembled county based amenity data on climati c environmental and urban conditions ranking of 253 urban counties reveals substantial variation within as well as among the 185 urba n areas the quality of life differences across counties within one s msa is almost one half of the difference between the top and bottom ranked counties in the nation copyright 1988 by american economic association

the amenity value of the italian climate the hedonics literature suggests that locations with more favourable characteristics should display compensating wage and house price differentials specifying climate in terms of january and july averages estimates of the marginal willingness to pay for small changes in climate variables are derived using this technique applied to italian data italians would prefer a drier climate during the winter months but higher summertime temperatures are shown to reduce welfare in some locations households would prefer to see clearer skies these results may have relevance to the task of determining the economic impact of future climate change c 2003 elsevier science usa all rights reserved

modeling the price dynamics of co2 emission allowances abstract in this paper we analyze the short term spot price behavior of carbon dioxide co 2 emission allowances of the new eu wide co 2 emissions trading system eu ets after reviewing the stylized facts of this new class of assets we investigate several approaches for modeling the returns of emission allowances due to different phases of price and volatility behavior in the returns we suggest the use of markov switching and ar garch models for stochastic modeling we examine the approaches by conducting an in sample and out of sample forecasting analysis and by comparing the results to alternative approaches our findings strongly support the adequacy of the models capturing characteristics like skewness excess kurtosis and in particular different phases of volatility behavior in the returns

is information assimilated at announcements in the european carbon market abstract we examine the high frequency new information impact on prices volatility trading volume and illiquidity at scheduled macroeconomic and verified emissions announcements for the european carbon futures market verified emissions united states non farm payroll and german new factory order macroeconomic announcements impact carbon prices swiftly within 5 min we show that a one standard deviation surprise increase in verified emission announcements is associated with an approximate ten percentage point 9 96 increase in carbon futures returns a wait and see stylized trading behavior is evident at announcements in volatility and trading volumes market illiquidity increases at announcements in relation to united states non farm payroll albeit there is no evidence of an increase in illiquidity prior to announcements the development of new information impact over time occurs mainly in the at announcement 5 minute time interval

carbon price drivers phase i versus phase ii equilibrium abstract the aim of this paper is to investigate the determinants of the carbon price during the two phases of the european union emission trading scheme eu ets more specifically relying on daily eu allowance futures contracts we test whether the carbon price drivers identified for phase i still hold for phase ii and evolve toward a long run relationship using cointegration techniques and accounting for the 2006 structural break in the carbon market we show that while a cointegrating relationship exists for both phases of the eu ets the nature of this equilibrium relationship is different across the two subperiods with an increasing role of fundamentals in phase ii deriving equilibrium values we show that the carbon price tends to be undervalued since the end of 2009

dealing with uncertainties when governing csr policies as corporate social responsibility involves a voluntary business endeavour to address social and environmental issues beyond legal compliance governments cannot fall back on hierarchical command and control policies to support it as such it is complementary with the increasing popularity of public policies known as new governance policies where the government is engaged in a horizontal inter organizational network of societal actors and where public policy is both formed and executed by the interacting and voluntary efforts from a multitude of stakeholders however such policies are known to generate substantive uncertainty about the content of csr and its related issues strategic uncertainty regarding the behavior of the actors involved and institutional uncertainty related to the interaction process involved in the institutional change we explore new governance policy instruments to address these uncertainties in the context csr and discuss the experiences with these methods in the european union

corporate social responsibility its economic impact and link to the bullwhip effect this paper examines the economic impact of implementing corporate social responsibility csr in the supply chain operations of multinational corporations mnc because they have global supply chains in emerging markets mncs face certain operational challenges for example unethical operations often result in a huge loss to mncs in the long run even though their initial cost seems to be low in this paper we extend the bullwhip effect theory in supply chain management to the ethical operations context and define and evaluate a special bullwhip effect due to unethical operations beuo using economic data from various sources including ford toyota and gm in the auto industry we first estimate the indices of beuo for the three companies and demonstrate the economic necessity for mncs to incorporate csr with supply chain operations we then propose a coherent approach blending what we term the bottom up and proactive methods to achieve such an outcome the bottom up approach requires mncs to switch their focus on stakeholders shifting from shareholders to consumers and workers and on decision levels from public relationships to supply chain operations the proactive approach recommends initializing specific csr operations to mitigate the negative impact of beuo both theoretical analysis and case studies are conducted to evaluate our developed propositions that mncs adopting the proposed csr operations will in the long run achieve better economic performance recommended actions for implementation based on best practices are also presented

fluidity of regulation csr nexus the multinational corporate corruption example corporate social responsibility csr is a relatively undeveloped concept despite its increasing importance to corporations one difficulty is the possible inexactness of csr another is the apparent reluctance by regulatory authorities and policy makers to intervene in the area this is largely a result of inhibitions created by traditional approaches to company law with emphasis on shareholder protection and financial disclosure the consequence is the stultification of independent development of csr by tying social issues to financial performance this attitude might not be unconnected to the theoretical and practical challenges in justifying csr and defining its scope the underlying impediment is a factual and theoretical failure to distinguish instrumental and pure ethical csr this article demonstrates that ethical csr highlights the role of regulation and a principal stance is that regulation is neither incompatible nor irreconcilable with ethical csr the article argues that cognizance of the intrinsic moral justification of pure csr is required for delineating the scope of csr as well as for clarifying the desirability and extent of its regulation it argues that the dynamic history and visage of multinational corporate corruption illuminates the fluidity of the regulation csr relationship the current and widening backlash against transnational corporate corruption is arguably a demonstration of the position that regulation and csr are not mutually exclusive and absolute concepts this article submits that recognition and application of this ethical and instrumental csr distinction is fundamental to the development of csr and resolution of connected questions of regulation

multivariate dependence and spillover effects across energy commodities and diversification potentials of carbon assets abstract in a first step we model the multivariate tail dependence structure and spillover effects across energy commodities such as crude oil natural gas ethanol heating oil coal and gasoline using canonical vine c vine copula and c vine conditional value at risk covar in the second step we formulate portfolio strategies based on different performance measures to analyze the risk reduction and diversification potential of carbon assets for energy commodities we identify greater exposure to losses arising from investments in heating oil and ethanol markets we also find evidence of carbon asset providing diversification benefits to energy commodity investments these findings motivate for regulatory adjustments in the trading and emission permits for the energy markets most strongly diversified by carbon assets

trader types and volatility of emission allowance prices evidence from eu ets phase i abstract this paper studies the relation between the trading activity of market participants and the volatility of the european emission allowance price during phase i of the european union emission trading system eu ets we focus on the contrasting roles of different trader types we find evidence of a positive and significant trading activity volatility relation which appears to be stronger when accounting for trader type the positive relation can be mainly attributed to energy providers in contrast industrial companies seem to have traded more frequently when volatility levels were lower finally the non liable players represented by financial intermediaries appear to have acted as a flexible counterparty trading more with the energy sector when volatility was higher and more with the industrial firms when volatility was lower we discuss possible explanations for these contrasted positions understanding the trading activity volatility link is relevant for evaluating the efficiency of the eu ets although the relation is generally positive many players remained often inactive and traded mostly when volatility levels were lower policies targeting the engagement of less active players could lead to a smoother incorporation of information into prices and to an increase in market efficiency

modeling heteroscedasticity in daily foreign exchange rates this article estimates autoregressive conditionally heteroscedastic arch and generalized arch garch models for five foreign currencies using 10 years of daily data a variety of arch and garch specifications a number of nonnormal error densities and a comprehensive set of diagnostic checks it finds that arch and garch models can usually remove all heteroscedasticity in price changes in all five currencies goodness of fit diagnostics indicate that exponential garch with certain nonnormal distributions fits the canadian dollar extremely well and the swiss franc and the deutsche mark reasonably well only one nonnormal distribution fits the japanese yen reasonably well none fit the british pound

fostering corporate social responsibility through public initiative from the eu to the spanish case should csr be approached only on a voluntary basis or should it be complemented with a compulsory regulatory framework what type of government intervention is more effective in fostering csr among companies this paper is an attempt to answer these questions reviewing the debate between proponents of the voluntary case and the obligatory case for csr and critically analysing current international government led initiatives to foster csr among companies and national government led initiatives in the eu area finally the paper focuses on the spanish case as an example of the failure of an exclusively voluntary approach despite the rapid uprise of csr spain is still far behind late in csr promotion strategies most action has been undertaken by companies themselves with no common guidelines governmental support or independent verification the lack of a regulatory framework for csr or ethical investment issues and the virtual absence of other indirect incentives explains the misbalance between private public and third sector initiatives based on the spanish context which is quite similar to other non oecd countries the authors call for a more proactive government position in csr related issues the conclusions of the paper detail the features of this regulatory framework and other policies to promote csr in spain as well as in other oecd countries

understanding volatility dynamics in the eu ets market abstract we study the short term price behavior of phase 2 eu emission allowances we model returns and volatility dynamics and we demonstrate that a standard armax garch framework is inadequate for this modeling and that the gaussianity assumption is rejected due to a number of outliers to improve the fitness of the model we combine the underlying price process with an additive stochastic jump process we improve the model s performance by introducing a time varying jump probability that is explained by two variables the daily relative change in the volume of transactions and the european commission s announcements regarding the supply of permits we show that i sharp increases in volume have led to increased volatility during the april 2005 december 2007 period but not for the period beginning in january 2008 and ii announcements induce jumps in the process that tend to increase volatility across both periods thus authorities face a trade off between disseminating information effectively and promoting market stability

how to improve the market efficiency of carbon trading a perspective of china abstract emissions trading scheme ets is one of the effective measures to realize energy conservation and emission reduction in order to set up a nationwide carbon emissions trading mechanism seven ets pilots have been launched in china firstly based on empirical investigation and research of seven pilots this paper analyzed the market efficiency of ets pilots from four aspects carbon price trading volume market liquidity and information transparency the result showed that the market efficiency of ets pilots is not satisfactory in spite of the fact that system designs of ets have achieved preliminary result then the reason for low market efficiency of ets pilots was discussed from some factors such as institutional arrangements market participants the supply and demand etc finally this paper puts forward some policy suggestions to improve the market efficiency of china s carbon trading market

improving the liquidity of china s carbon market insight from the effect of carbon price transmission under the policy release abstract through a series of policies release the trading system of china s carbon market is being improved but its current liquidity is still low to improve market liquidity this paper analyzes the relation between the release of policy related to carbon market operations and the volatility of carbon price thus arranging an optimal adjustment scheme for government s policy making through the jump test and logit regression we investigate historical policies and prices of 7 emission trading scheme pilots in china to explore the impact of policy release on carbon price and then quantify the effectiveness of these policies empirical results indicate that in the short term new policies can rapidly lead to a large volatility of carbon price but it can also reduce the abnormal volatility with the spread of price information further the demand stimulus policies promote a positive volatility of carbon price in the long term the insufficient demands for carbon emissions quota raise the disappearance of market dividends caused by the policy release and lead to an excessive call back of carbon price thus increasing mid and long term risks in carbon markets additionally china s macro environment policy can stabilize carbon price and thus an effective tool for improving the liquidity of carbon markets is developing demand stimulus policies

dynamic behavior of co2 spot prices co2 emission allowances are traded nowadays over the counter otc and on exchanges across the european union eu it thus becomes increasingly important for traders of these emission certificates to have a valid co2 spot price model to value potential derivatives in addition co2 emitting companies require an adequate co2 spot price model in order to better assess their production costs and support emissions related investment decisions however sufficient price history is still lacking for the european union emission trading scheme eu ets we therefore present a tractable stochastic equilibrium model reflecting stylized features of the eu ets and analyze the resulting co2 spot price dynamics our main findings are that co2 prices do not have to follow any seasonal patterns discounted prices should possess the martingale property and an adequate co2 price process should exhibit a time and price dependent volatility structure a brief empirical examination regarding market efficiency complements our analysis
