role of carbon swap trading and energy prices in price correlations and volatilities between carbon markets the present paper theoretically and empirically examines the role of carbon swap trading and energy prices in volatilities and price correlations between the eu and kyoto protocol emissions trading schemes a supply and demand based correlation model between eua and scer price returns is proposed in detail using inverse box cox type marginal abatement cost mac curves and simple emission reduction volume processes the model includes financial players eua scer swap transaction in boom periods of carbon prices using the logit model for eua and eua scer swap volume correlations and stronger energy price impacts on eua prices than scer prices using a mean reverting lognormal process for energy prices the empirical studies using eua and scer prices estimate the model parameters resulting in a positive eua volume impact on eua scer swap transactions and a positive energy price impact on eua prices it is shown that high eua scer price correlations during high eua price periods stemmed from eua scer swap transactions whereas high eua scer price correlations during the period of financial turmoil with low eua prices came from the drop in energy prices we also show that the leverage effects often observed in security markets exist in both the eua and scer markets according to the price volatility relation

monetary union in west africa and business cycles synchronicity new evidence in the light of the initiative of the west african monetary zone wamz to introduce a common currency by 2020 this paper investigates the intricacies of the business cycles synchronicity among the six countries given i the rising importance of trade and cooperation with china ii the consideration of the euro as a potential anchor currency and a vehicle for trade with the eurozone and iii the importance of nigeria as the largest country of the group and the main supplier of oil we investigate the relative importance of these three major players in having their business cycles linked with the group in addition we investigate the underlying determinants of the business cycles synchronicity among the wamz countries on a pairwise basis results show a clear dominance of china s business cycle synchronicity with the wamz over europe s and nigeria s trade integration emerges as the key underlying factor of the common cycle observed

energy consumption at business cycle horizons the case of the united states in this paper we propose a simple extension to a keynesian type macro model by augmenting it with energy consumption we show the relationship between energy consumption and output in a macroeconomic setting and ask the question do permanent shocks dominate changes in energy consumption and output at business cycle horizons for the united states to achieve the goal of this paper we undertake a variance decomposition analysis of shocks based on a common trend and common cycle framework within a vector error correction model our main finding is that permanent shocks explain the bulk of the variations in energy consumption and output at business cycle horizons for the united states

monetary policy synchronization in the asean 5 region an exchange rate perspective in light of the long standing vision of economic and monetary integration in the asean association of southeast asian nations region and the importance of coordinating monetary policies to achieve it the objective of this article is to assess the monetary policy synchronization among the founding members of the asean that is indonesia malaysia the philippines singapore and thailand due to the importance of exchange rate movements to monetary policies we approach this issue from a currency exchange rate perspective specifically multivariate trend cycle decomposition is employed to investigate common trends and common cycles among the exchange rates of these countries during the period 1976 2012 our analysis reveals that the real exchange rates of malaysia the philippines singapore and thailand share common cycles in the short term and have common trends in the long term but the indonesian currency does not share these relationships thus our results augur well for the synchronization of mo

common trends and common cycles the existence of a serial correlation common feature among the first differences of a set of i 1 variables implies the existence of a common cycle in the beveridge nelson stock watson decomposition of those variables a test for the existence of common cycles among cointegrated variables is developed the test is used to examine the validity of the common trend common cycle structure implied by flavin s excess sensitivity hypothesis and campbell and mankiw s mixture of rational expectations and rule of thumb hypothesis for consumption and income linear independence between the cointegration and the cofeature vectors is exploited to decompose consumption and income into their trend and cycle components copyright 1993 by john wiley sons ltd

an unobserved components model that yields business and medium run cycles we generalize the unobserved components uc model to allow the permanent component to have different dynamics than the transitory components when decomposing u s economic activity using a multivariate uc model of log output consumption and investment we find that these proposed dynamics in the permanent component are statistically significant and distinct from those of the transitory components our approach provides an alternative explanation for the growth cycles identified by comin and gertler 2006 that is related to the cyclical movements in technology in a framework consistent with the beveridge and nelson 1981 decomposition

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

progressivity horizontal equity and reranking in health care finance a decomposition analysis for the netherlands this paper employs the method of aronson et al 1994 to decompose the redistributive effect of the dutch health care financing system into three components a progressivity component a classical horizontal equity component and a reranking component results are presented for the health care financing system as a whole as well as for its constituent parts a final section sets out to uncover the relative importance in terms of their effects on progressivity horizontal equity and reranking of the key institutional features of one component of the dutch system the awbz social insurance scheme

the redistributive effect of health care finance in twelve oecd countries the oecd countries finance their health care through a mixture of taxes social insurance contributions private insurance premiums and out of pocket payments the various payment sources have very different implications for both vertical and horizontal equity and on redistributive effect which is a function of both this paper presents results on the income redistribution consequences of the health care financing mixes adopted in twelve oecd countries by decomposing the overall income redistributive effect into a progressivity horizontal inequity and reranking component the general finding of this study is that the vertical effect is much more important than horizontal inequity and reranking in determining the overall redistributive effect but that their relative importance varies by source of payment public finance sources tend to have small positive redistributive effects and less differential treatment while private financing sources generally have larger negative redistributive effects which are to a substantial degree caused by differential treatment

some consequences of temporal aggregation in empirical analysis i derive the generating mechanism of a temporally aggregated process when the disaggregated one belongs to the vector autoregressive integrated moving average class i then study the effects of temporal aggregation on a set of characteristics of usual interest such as exogeneity causality cointegration and common features an empirical example with canadian interest rates illustrates the main issues

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

forecasting the volatility of australian stock returns do common factors help this article develops multivariate factor models for forecasting volatility in australian stocks we suggest estimation procedures for approximate factor models that are robust to jumps when the cross sectional dimension is not very large and also work with volatility measures that have been constructed so that they contain no jump components out of sample forecast analysis shows that multivariate factor models of volatility outperform univariate models but there is little difference between simple and sophisticated factor models

the clean development mechanism stochastic permit prices and energy investments abstract we analyze the impact on energy investments stemming from different emission permit classes by considering permits that are allocated inside the european emission trading scheme and secondary certified emission reduction scer permits originating from the clean development mechanism one price taking firm which is subject to emission regulation has the choice to invest in gas or wind power plant the firm faces uncertainty regarding stochastically evolving permit prices while it receives a premium on the electricity price for wind energy as a first step we determine the value of the option to invest into a gas power plant over time then we calculate the investment probability of a gas power investment in a range of policy scenarios we find that allowing the usage of scer permits in the present policy framework has a positive impact on gas power investment decoupling the price processes has a similar effect if the quota of scer permits is doubled the decrease in the investment probability for wind power is large we carry out sensitivity tests for different parameter values and find that investment behavior changes significantly with differing interest rates the wind energy premium and volatility

multicointegration in us consumption data the present study tests for the existence of multicointegration between real per capita private consumption expenditure and real per capita disposable personal income in the usa in doing so the study exploits the fact that the flows of disposable income and consumption expenditure on the one hand and the stock of consumers wealth which can be considered as cumulative past discrepancies between the flows of income and expenditure on the other hand can be thought of as a stock flow model in which multicointegration is likely to occur recently developed i 2 techniques are applied for testing for multicointegrating relations and find supporting evidence for the existence of multicointegration in us consumption data

long memory and aggregation in macroeconomic time series this paper explores the interaction between long memory and aggregation results are derived which link the possibly fractional orders of integration of the aggregate series with those of the underlying series when the aggregation is either cross sectional or temporal in discrete or continuous time these results provide empirically testable hypotheses that are examined using six u k macroeconomic series a semiparametric method is found to be broadly consistent with the implications of the theory but fully parametric arfima models show considerable variation each series appears to be integrated of an order of between one and one and a half

redistribution effect and unequal income tax treatment decomposing the post tax gini coefficient across groups of pre tax equals reveals the separate contributions to the redistributive effect of an income tax of 1 the effective schedule the vertical effect 2 the unequal treatment of equals arising from departures from this effective schedule the horizontal effect and 3 the reranking of unequals as a result of such departures the reranking effect the methodology is applied to u k microdata throughout the period 1978 91 reranking understates the negative contribution to redistributive effect of unequal tax treatment by about one third and is far outweighed by the vertical effect copyright 1994 by royal economic society

equity in health care finance in palestine the triple effects revealed this paper presents an application of the urban and lambert upgraded ajl decomposition approach that was designed to deal with the problem of close income equals in equity analysis and as applied to the area of health care finance contrary to most previous studies vertical and horizontal inequities and the triple effects of inter groups intra group and entire group reranking of various financing schemes are estimated with statistical significance calculated using the bootstrap method application is made on the three financing schemes present in the case of the occupied palestinian territory results demonstrate the relative importance of the three forms of reranking in determining overall inequality the paper offers policy recommendations to limit the existing inequalities in the system and to enhance the capacity of the governmental insurance scheme

on the persistence of the eonia spread abstract the european overnight rate eonia signals the monetary policy stance of the european central bank controllability of the eonia requires that the persistence of the spread between the eonia and the key policy rate remains sufficiently low we apply fractional integration techniques to examine its changing persistence

why is consumption so smooth for thirty years it has been accepted that consumption is smooth because permanent income is smoother than measured income this paper considers the evidence for the contrary position that permanent income is in fact less smooth than measured income so that the smoothness of consumption cannot be straightforwardly explained by permanent income theory the paper argues that in postwar u s quarterly data consumption is smooth because it responds with a lag to changes in income

testing for codependence of cointegrated variables we analyse nonstationary time series that do not only trend together in the long run but restore the equilibrium immediately in the period following a deviation while this represents a common serial correlation feature the framework is extended to codependence allowing for delayed adjustment we show which restrictions are implied for the moving average ma and vector error correction model vecm representations and put forward a generalized method of moments gmm test in addition for cases where the constraints can be uniquely imposed on a vecm a likelihood ratio test is proposed we apply the concept to us and european interest rate data examining the capability of the federal reserve bank fed and european central bank ecb to control overnight money market rates

statistical inference of progressivity dominance an application to health care financing distributions this paper employs a distribution free statistical test suitable for comparisons based on dependent samples to analyse changes in health care financing distributions on finnish data in distinction to the more general summary index approach used in most studies of progressivity measurement the difference between the lorenz curve of income inequality and the concentration curves of various taxes and payments is used to evaluate progressivity dominance and changes in progressivity sample weights are applied to account for the effect of sampling design and non response the analysis demonstrates that the dominance approach can be successfully applied to various types of distributional problems besides comparisons concerning differences in income distributions as an empirical application the paper presents estimation results for the progressivity of various health care financing sources using data from the 1987 and 1996 finnish health care surveys

linking with uncertainty the relationship between eu ets pollution permits and kyoto offsets carbon offsets from the kyoto flexible mechanisms can be used by firms in the eu emissions trading scheme for compliance in lieu of eu allowances making these carbon assets interchangeable we offer an explanation of the price spread using a structural model of the price for certified emissions reductions that combines three features a limit for the use of kyoto offsets within the eu ets a disconnect between the current price of offsets and their marginal cost of production for institutional reasons and uncertainty about future supply and demand of offsets our model expresses the offset price as an average of the eu allowance price and an offset s outside value weighted by the probability of a binding import limit using a monthly series of the united nation s clean development mechanism and joint implementation about offset supply and demand we provide empirical support for our theory of offset price formation counterfactual simulations suggest that the price process is dominated by uncertainty

recent advances in modelling seasonality abstract in this paper we review recent developments in econometric modelling of economic time series with seasonality the prime focus is on econometric models which incorporate explicit descriptions of seasonal variation instead of removing this variation using a seasonal adjustment method this review centres around developments in seasonal unit root models and in periodic parameter models both in the univariate and multivariate context several empirical examples are used for illustration we also discuss several areas for further research

are shocks to tourism transitory at business cycle horizons the goal of this article is to propose a theoretical framework based on a macro model that can be used to examine the relative importance of permanent and transitory shocks in explaining variations in tourist expenditure and gross domestic product gdp at business cycle horizons we estimate the model for australia our findings reveal a common trend and common cycle relationship among tourist expenditure and gdp and the variance decomposition analysis of shocks reveals that at business cycle horizons permanent shocks explain the bulk of the variations in output while transitory shocks explain the bulk of the variations in tourist expenditure

business cycles under monetary union a comparison of the eu and us reserve districts in the usa and the 15 countries that make up the eu the comparison is suggestive of what might be expected to emerge in the way of business cycle synchronization from a monetary union between the member states of the eu now simply non decimal denominations of the euro and the national central banks of the 11 are branches of the european system of central banks many prominent observers doubted that europe would ever reach this stage and many continue to believe that monetary union between such a large and dispar ate group of countries is fundamentally unsound a key element in the argu ments of many critics of emu is the degree of business cycle asynchronicity between the member states of the eu this paper contributes to the ongoing debate by documenting key differences and similarities between business cycles in the eu and business cycles in the 12 federal reserve districts in the united states the practice of looking to the us experience for insights into the problems and functioning of a monetary union has a long precedent in the literature on fixed exchange rates in general and in the literature on emu in particular for example in making an argument for fixed exchange rates rolnick and weber 1994 note that the usa can be viewed as having a system of fixed exchange rates between currencies issued by the 12 regional federal reserve banks they argue that the notes issued by the 12 banks are not strictly ident ical and that the difference between the notes creates the possibility that the united states could have a system of floating exchange rates among the 12 federal reserve districts 1 rolnick and weber go on to examine the features of the relationship among the 12 regional federal reserve banks that make a system of fixed exchange rates between them feasible in the process drawing lessons for how a monetary union among the countries of the eu might work the analysis in this paper complements earlier analyses in a number of ways the resurgence of interest in business cycle research over the past 20

eua and scer phase ii price drivers unveiling the reasons for the existence of the eua scer spread abstract this article studies the price relationships between eu emissions allowances euas valid under the eu emissions trading scheme eu ets and secondary certified emissions reductions scers established from primary cers generated through the kyoto protocol s clean development mechanism cdm given the price differences between euas and scers financial and industrial operators may benefit from arbitrage strategies by buying scers and selling euas i e selling the eua scer spread to cover their compliance position as industrial operators are allowed to use scers towards compliance with their emissions cap within the european system up to 13 4 our central results show that the spread is mainly driven by eua prices and market microstructure variables and less importantly as we would expect by emissions related fundamental drivers this might be justified by the fact that the eu ets remains the greatest source of cer demand to date

costs of certified emission reductions under the clean development mechanism of the kyoto protocol abstract this paper examines the cost structure of certified emission reductions cers through various types of projects under the clean development mechanism cdm of the kyoto protocol using the cdm project data the costs of cers and their variation across technology and over time and space are estimated by applying alternative functional forms and specifications results show that the average cost of cers decreases with the project scale and duration scale and duration effects significantly vary across project types and there is an upward trend in costs the results also show that the distribution of the projects in the cdm portfolio or a given location does not strictly follow the relative cost structure nor does the distribution of the cdm projects in different host countries follow the principle of comparative advantage more than 84 of the cdm portfolio consists of various energy projects with substantially higher costs of cers than afforestation and reforestation industrial and landfill gas reduction and methane avoidance projects which are only 12 of all projects while per unit cost of abatement plays an important role in the bottom up and top down models to evaluate emission reduction potential and analyze policy alternatives the findings contradict the presumption of such models that project investors seek out low cost opportunities at the aggregate level the cost of cer by the projects in asia and europe is similar but higher than those hosted in africa americas and oceania yet more than 83 of the projects in the cdm portfolio are located in asia more than 69 of the projects are in china and india alone china appears to have a comparative advantage i e lowest opportunity cost in energy efficiency projects while india has a comparative advantage in hydro power projects and brazil has a comparative advantage in wind power projects in contrast energy efficiency category accounts for only 8 of the cdm projects in china hydro power accounts for 12 of the projects in india and wind power accounts for 18 of the projects in brazil the results provide a basis for evaluating the incentives that the mechanism offers as a cost effective policy instrument that balances greenhouse gas mitigation across sectors and regions while fulfilling the objective of the convention

modelling the price spread between eua and cer carbon prices abstract this paper identifies factors impacting on the dynamics of the price spread between european allowances euas and certified emission reductions cers by detecting changes in the structural relationship between them while prior studies have assumed a fixed structural relationship this paper analyses the dynamic evolution of the price spread by employing a time varying parameter analysis using daily data from march 2008 to september 2011 the analysis reveals that a lack of competitive conditions in markets access constraints on the use and the availability of cers regulatory changes regarding both euas and cers and uncertainty surrounding cers can explain a significant portion of the price spread

monetary policy implementation and the federal funds rate this paper investigates how the implementation of monetary policy affects the dynamics and the volatility of the federal funds rate since the early 1980s the most important changes in the fed s conduct of monetary policy refer to the role of the federal funds rate target and the reserve requirement system we show that the improved communication and transparency regarding the federal funds rate target has significantly increased the fed s influence on the federal funds rate since 1994 by contrast the declining role of required reserves in the u s has contributed to higher federal funds rate volatility our results suggest that the planned introduction of remunerated reserves will further enhance the controllability of the federal funds rate

what moves oecd real interest rates this paper conducts a structural time series analysis of ex ante real interest rates of the five major oecd economies the relationships of rates to permanent and temporary real and nominal shocks appear to be qualitatively consistent with predictions of stochastic general equilibrium business cycle models u s real and nominal shocks are found to be the most important causes of persistence in rates but only nominal shocks cause dynamic movements that are coherent across all countries the rise in real interest rates in the early 1980s was mainly due to nominal shocks real shocks played little or no role

what can new survey data tell us about recent changes in distribution and poverty it has been claimed that in recent times the poor have lost ground both relatively and absolutely even when average levels of living have risen this article tests that claim using household surveys for 67 developing and transitional economies over 1981 94 it finds that changes in inequality and polarization were uncorrelated with changes in average living standards distribution improved as often as it worsened in growing economies and negative growth was often more detrimental to distribution than positive growth overall there was a small decrease in absolute poverty although with diverse experiences across regions and countries almost always poverty fell with growth in average living standards and rose with contraction

integration of the global carbon markets abstract this paper analyzes the market architecture and common factors of emission reduction instruments in europe and north america spot and futures prices across exchanges in europe are cointegrated but the futures curve beyond the calendar year evolves independently despite narrower spreads political uncertainties about the clean development mechanism have kept eua and cer prices from converging rggi allowances share a common trend with eua and the european markets adjust to the u s price trend a 0 10 shock to rggi prices leads to a one month 0 64 cumulative increase in eua prices the introduction of cap and trade legislation in the u s has broken a cointegrating relationship in voluntary prices voluntary instruments that are convertible into mandatory allowances imply less than a 20 probability of price convergence between the u s and europe by 2013

pricing emission permits in the absence of abatement abstract if emissions are stochastic and firms are unable to control them through abatement the cap in a permit market may be exceeded or not be reached i derive a binary options pricing formula that expresses the permit price as a function of the penalty for noncompliance and the probability of an exceeded cap under the assumption of no abatement i apply my model to the eu ets where the rapid introduction of the market made it difficult for firms to adjust their production technology in time for the first phase the model fits the data well implying that the permit price may have been driven by firms hedging against stochastic emissions
