further evidence on the variability of inflation and relative price variability abstract using a sample of monthly observations of both a 12 category group and a 203 category group of personal consumption expenditures we furnish evidence that relative price variability is positively related to both the inflation rate and inflation variability the relation is robust to oil price shocks

induced institutional change in the trade and environment debate because of the assumption of constant emission factors economy environment models often show that free trade has negative environmental consequences however this pessimistic view ignores the possibility of trade strengthening the demand for regulatory institutions an institutional optimism hypothesis stating that the net environmental result of trade liberalization is benign is thus formulated in this paper the hypothesis is examined with a cge model that treats institutional change as an endogenous process dependent on income application to nafta using a broad range of scenarios provides some support for the institutional optimism hypothesis the net pollution effect of trade liberalization is in many cases beneficial or low even for the country specializing in polluting industries the implication is that in many cases environmental interests are served better by a focus on institution building in trading partners than on the process of trade liberalization itself

determinants of co2 emissions in a small open economy abstract the aim of the paper is to explore the relationship between economic development and carbon dioxide co2 emissions for a small open and industrialized country austria we test whether an environmental kuznets curve relationship also holds for a single country rather than concentrating on panel or cross section data for a set of countries a cubic i e n shaped relationship between gdp and co2 emissions is found to fit the data most appropriately for the period 1960 1999 and a structural break is identified in the mid seventies due to the oil price shock furthermore two variables are additionally significant import shares reflecting the well known pollution haven hypothesis and the share of the tertiary service sector of total production gdp accounting for structural changes in the economy emission projections derived from this single country specification support the widely held opinion that significant policy changes are asked for when implementing the kyoto protocol in order to bring about a downturn in future carbon emissions

a further interpretation of friedman s hypothesis the cointegration of component cpi indexes abstract this study extends the friedman 1977 friedman m 1977 nobel lecture inflation and unemployment journal of economic dynamics and control 12 231 254 hypothesis regarding inflation means and variances to show that high inflation is also associated with greater divergence of component inflation indexes over time this finding follows friedman s reasoning involving inflation uncertainty and time lagged adjustments

swedish co2 emissions 1900 2010 an exploratory note abstract this paper projects swedish co 2 emissions during the period 2000 2010 based on data covering 1900 1999 swedish climate policy is currently based on the assumption that carbon emissions will increase ceteris paribus by 5 15 relative to the 1990 level this forecast has motivated a number of policy measures including carbon taxes subsidies and an information package we find however that co 2 emissions may well be lower in the future this outcome is broadly consistent with the literature on the environmental kuznets curve which portrays the relationship between emissions and gdp the key contribution of this paper is that our analysis is based on a long time series current literature is invariably based on short panel data sets while we study a single country through several phases of development our analysis also sheds some light on the key importance played by nuclear power for carbon emission projections

is the income elasticity of environmental improvements less than one we estimated the income elasticity of environmental improvements for a number of european data sets the value of this parameter is consistently found to be less than one with few exceptions our findings are compared with state of the art contingent valuation studies from other countries we also compared our findings with those reported in the literature on charitable donations and corporate donations these studies show a similar pattern donations decrease as a percentage of income as income increases

transboundary effects of environmental policy markets and emission leakages abstract one of many explanations for environmental kuznets curves for rich countries can be that dirty production is relocated to economies with laxer abatement regimes if this is caused by national abatement policies environmental stresses are transferred to other countries further the economic costs of national abatement policies can be shared with foreigners to some extent both through a lower demand for imports and losses of market shares for foreign competitors that produce cleaner products we quantify effects internally and abroad of a growth induced unilateral carbon tax policy in a rich open economy we find that the environmental benefits fall and the economic costs rise when a global rather than a national perspective is employed

relationship between inflation rate and inflation uncertainty abstract to shed further light on the possible link between inflation rate and inflation uncertainty the paper explores the relationship for us monthly inflation over 1926 to 1992 with various arfima garch type models it found that the inflation affected its uncertainty weakly negatively whereas the uncertainty affected the inflation insignificantly the results were robust to the high inflation period of the 1970s and the volatile period of 1929 to 1945 it supports engle s result that a high rate of inflation does not necessarily imply a high variance of inflation unlike friedman s view that a high rate of inflation leads to a high variance of inflation

trade the pollution haven hypothesis and the environmental kuznets curve examining the linkages abstract this paper examines the extent to which the ekc inverted u relationship can be explained by trade and specifically the migration or displacement of dirty industries from the developed regions to the developing regions the pollution haven hypothesis phh using detailed data on north south trade flows for pollution intensive products the evidence for the phh is assessed emissions of 10 air and water pollutants are then estimated controlling for trade openness structural change and dirty north south trade flows evidence of pollution haven effects is found although such effects do not appear to be widespread and appear to be relatively small compared to the roles played other explanatory variables

economic growth trade and energy implications for the environmental kuznets curve abstract the environmental kuznets curve ekc hypothesis asserts that pollution follows an inverted u path with respect to economic growth the ekc has been explained in terms of structural changes in the composition of economic output and increased environmental regulation at higher income levels while some authors have incorporated the impact of trade policy orientation on the ekc the impact of the actual movement between countries of goods that embody pollution has not been considered this paper attempts to econometrically quantify the effect using pooled cross country and time series data the ekc hypothesis is examined with respect to commercial energy consumption the source of many serious environmental problems it was found that while both industrializing and industrialized countries have added to their energy requirements by exporting manufactured goods the growth has been substantially higher in the former at the same time industrialized countries have been able to reduce their energy requirements by importing manufactured goods exports of manufactured goods by industrialized countries has thus been an important factor in generating the upward sloping portion of the ekc and imports by industrialized countries have contributed to the downward slope

economic growth and greenhouse gas emissions abstract recent empirical research has examined the relationship between certain indicators of environmental degradation and income concluding that in some cases an inverted u shaped relationship which has been called an environmental kuznets curve ekc exists between these variables unfortunately this inverted u shaped relationship does not hold for greenhouse gas emissions one explanation of the absence of ekc like behavior in greenhouse gas emissions is that greenhouse gases are special pollutants that create global not local disutility but the international nature of global warming is not the only reason that prevents de linking greenhouse gas emissions from economic growth the intergenerational nature of the negative impact of greenhouse gas emissions may have also been an important factor preventing the implementation of greenhouse gas abatement measures in the past in this paper we explore the effect that the presence of intergenerational spillovers has on the emissions income relationship we use a numerically calibrated overlapping generations model of climate economy interactions we conclude that 1 the intertemporal responsibility of the regulatory agency 2 the institutional capacity to make intergenerational transfers and 3 the presence of intergenerationally lagged impact of emissions constitute important determinants of the relationship between economic growth and greenhouse gas emissions

a two factor model to combine us inflation forecasts the combination of individual forecasts is often a useful tool to improve forecast accuracy the most commonly used technique for forecast combination is the mean and it has frequently proved hard to surpass this study considers factor analysis to combine us inflation forecasts showing that just one factor is not enough to beat the mean and that the second one is necessary the first factor is usually a weighted mean of the variables and it can be interpreted as a consensus forecast while the second factor generally provides the differences among the variables and since the observations are forecasts it may be related with the dispersion in forecasting expectations and in a sense with its uncertainty within this approach the study also revisits friedman s hypothesis relating the level of inflation with expectations uncertainty at the beginning of the twenty first century

dirty industries patterns of change in industrial countries this article concerns itself with the environmental role of heavily polluting industries since 1970 analysing its development in 11 basic industries as well as electricity production and road transport in 32 industrial countries it argues for a green industrial policy demonstrating that other mitigations of environmental pressure in industrial countries end of pipe treatment relocation to the third world structural change in the industrial sector and even environmentally oriented modernization have so far been unable to solve the problems of dirty industries although some approaches have shown some promise

changing inflation dynamics and uncertainty in the united states garch estimation we investigate recent changes in the level persistence and uncertainty of u s inflation despite the great strides in lowering inflation in the 1980s and 1990s we find that uncertainty has risen palpably in the current decade this is disturbing given the aforementioned findings of the negative impact of inflation uncertainty on output moreover analyzing both the standard consumer price index cpi and the cpi minus energy our results suggest that volatile energy costs contribute to the higher inflation uncertainty in the united states in the current decade

intra industry trade and industry distribution of productivity a cournot ricardo approach this paper constructs a cournot ricardo model of trade by incorporating cournot competition in a ricardian trade model in this model the share of intra industry trade in bilateral trade volume decreases as trading partners become more different in terms of the industry distribution of labor productivity we show that this relationship is a special case of a more general relationship the share of intraindustry is decreasing in a specialization index this specialization index turns out to be equal to the difference in the industry distribution of productivity in the case of our cournot ricardo model while it is given by the difference in capital labor in the well known case of monopolistic competition as both technologies and factor endowments would be important in shaping specialization patterns in the real world we conjecture that the share of intra industry trade is decreasing in two measures of specialization the difference in the industry distribution of productivity and the difference in capital ratio our ols estimations strongly support this conjecture in fixed effects regressions both measures lose significance in the entire sample but the industry distribution of productivity is significant in explaining trade between high income countries

stochastic volatility in a macro finance model of the u s term structure of interest rates 1961 2004 this paper generalizes the standard homoscedastic macro finance model by allowing for stochastic volatility using the square root specification of the mainstream finance literature empirically this specification dominates the standard model because it is consistent with the square root volatility found in macroeconomic time series thus it establishes an important connection between the stochastic volatility of the mainstream finance model and macro economic volatility of the okun friedman type this research opens the way to a richer specification of both macro economic and term structure models incorporating the best features of both macro finance and mainstream finance models

causality between inflation and real growth abstract the paper investigates inflation growth causality over 1947 2005 with varma ml asymmetric vgarch the results imply that one uncertainty affects positively its level and much less negatively the other level whereas one level influences positively both uncertainties friedman s hypothesis was not strongly rejected

air pollution and dirty industries how and why does the composition of manufacturing output change with economic development this paper examines the impact on air pollution ofchanges in the composition of manufacturing output indeveloped and developing countries pollutionemissions from manufacturing output are estimated ina manner which holds constant the effect of technologyand regulations allowing the impact of compositional changes alone on pollution to beestimated the paper has three main findings 1 theinverted u estimated between per capita income and thepollution intensity of gdp arises due to both thecomposition of manufacturing becoming cleaner and theshare of manufacturing output in gdp falling compositional changes alone are not responsible forthe inverted u between per capita income and percapita emissions 2 changes to the composition ofmanufacturing output are consistent with the pollutionhaven hypothesis however there is clear evidence thatrising per capita incomes are associated with afalling income elasticity of demand for dirty products this fact may explain the compositionalchanges that occur with development 3 in additionto the income elasticity effect the analysis suggeststhat land prices and to a lesser extent the prices oflabour and capital determine the proportion of dirtyindustry within a country s manufacturing sector

high and variable inflation further evidence on the friedman hypothesis abstract this study employing a garch model finds a positive and significant relationship between the level and variability of inflation this provides evidence in support of friedman s friedman 1977 view that high inflation leads to more variable inflation

optimal monetary policy under low trend inflation abstract in the monetary policy literature it is common to assume that trend inflation is zero despite overwhelming evidence that zero inflation is neither empirically relevant nor a practical objective for central bank policy we therefore extend the standard new keynesian model to allow for positive trend inflation showing that even low trend inflation has strong effects on optimal monetary policy and the dynamics of inflation output and interest rates under discretion the efficient policy deteriorates and there is no guarantee of determinacy even with commitment targeting non zero trend inflation leads to substantial welfare losses our results serve as a warning against indiscriminate use of models assuming zero trend inflation

estimates of the variance of u s inflation based upon the arch model it is generally agreed that the unpredictability of future inflation is a major component of the welfare loss associated with inflation perfectly predicted inflation might induce some costs through institutional rigidities governmental interference and transaction costs but in the long run these should be rather minimal as these institutions adopt various forms of indexing when inflation is unpredictable risk averse economic agents will incur a loss even if prices and quantities are perfectly flexible in all markets inflation is a measure of the relative price of goods today and goods tomorrow thus uncertainty in tomorrow s price impairs the efficiency of today s allocation decisions friedman in his nobel lecture 8 argues convincingly that higher variability of inflation would lead to decreased output ceteris paribus he then conjectures that higher rates of inflation are generally associated with higher variability of inflation and presumably greater uncertainty about future rates if this is true then higher rates of inflation would also be associated with low levels of output which implies a positively sloped phillips curve this paper uses a new statistical technique arch to estimate the conditional mean and variance of inflation from u s time series data the main finding is that the variance of inflation in the seventies was only slightly greater than in the sixties

factors behind the environmental kuznets curve a decomposition of the changes in air pollution the environmental kuznets curve theory suggeststhat economic growth in the long run may reduceenvironmental problems in this article we usea decomposition analysis to isolate eightdifferent factors in order to investigate theorigins of changes in emissions to air over theperiod from 1980 to 1996 among these factorsare economic growth changes in the relativesize of production sectors and changes in theuse of energy given constant emissions perproduced unit economic growth alone would havecontributed to a significant increase in theemissions this potential degradation of theenvironment has been counteracted by first ofall more efficient use of energy and abatementtechnologies in addition the substitution ofcleaner for polluting energy types and othertechnological progressions and politicalactions have reduced the growth in emissions consequently the growth in all emissions hasbeen significantly lower than economic growth and negative for some pollutants the results indicate that policymakers mayreduce emissions considerably through creatingincentives for lower energy use andsubstitutions of environmental friendly forenvironmental damaging energy types inaddition to support environmental friendlyresearch or to conduct direct emission reducingactions such as abatement requirements orbanning of environmental damaging products this is particularly relevant to countries andsectors with relatively high energy intensitiesand low pollution abatement
