the structure of unemployment we test for a unit root in postwar unemployment rates for sixteen oecd countries when a one time structural break is incorporated the unit root hypothesis can be rejected for most of the countries and the measured persistence of unemployment falls dramatically we then test for multiple structural changes and find evidence of one or two breaks for those countries for which the unit root hypothesis could be rejected almost all of the breaks are positive reflecting the sustained rise in european unemployment the major exception is the united states where long term unemployment rose in the 1970s and fell in the 1980s

the turning black tide energy prices and the canadian dollar the authors revisit the relationship between energy prices and the canadian dollar in the amano and van norden 1995 equation which shows a negative relationship such that higher real energy prices lead to a depreciation of the canadian dollar

tracking the slowdown in long run gdp growth using a dynamic factor model that allows for changes in both the long run growth rate of output and the volatility of business cycles we document a significant decline in long run output growth in the united states our evidence supports the view that most of this slowdown occurred prior to the great recession we show how to use the model to decompose changes in long run growth into its underlying drivers at low frequencies a decline in the growth rate of labor productivity appears to be behind the recent slowdown in gdp growth for both the united states and other advanced economies when applied to real time data the proposed model is capable of detecting shifts in long run growth in a timely and reliable manner

money velocity and the natural rate of interest abstract m1 velocity is approximately the permanent component of the short term rate this implies that agents in deciding how much wealth to allocate to non interest bearing m1 as opposed to interest bearing assets almost uniquely react to permanent shocks to the opportunity cost essentially ignoring transitory shocks this suggests that money demand models must be modified to allow for such distinct reaction to permanent and transitory variation in the opportunity cost of holding m1 under monetary regimes making inflation stationary permanent fluctuations in m1 velocity uniquely reflect to a close approximation permanent shifts in the natural rate of interest

measuring inflation expectations a survey data approach expectations of inflation can be important determinants of actual inflation because they influence the process of wage bargaining price setting speculative buying and financial investing decisions englander and stone 1989 a central bank given its primary objective of price stability therefore takes a natural interest in inflationary expectations of economic agents in fact as illustrated by the theoretical work of e g kydland and prescott 1977 and barro and gordon 1983 inflationary expectations of the public are an important factor determining the success of the central bank in achieving its policy goal measures of inflation expectations can be used for monetary policy purposes for example as information variables in the sense defiined by friedman 1993 or as intermediate targets in the so called direct inflation targeting strategy svensson 1996 fuhrer 1997

uncovering financial market expectations of inflation this paper seeks to uncover market expectations of inflation from the joint dynamics of nominal interest rates and observed inflation i postulate 1 the existence of a stable vector autoregression in unobserved variables and 2 efficient financial markets the estimation procedure requires no further structural assumptions the econometrician need not observe all the information used by agents in forming forecasts or all the variables that influence real interest rates i find no empirical evidence that economic recessions are correlated with inflation forecast errors however postwar recessions are associated with ex ante real interest rates that are twice the postwar average

pooling forecasts in linear rational expectations models abstract estimating linear rational expectations models in a limited information setting requires replacing the expectations of future endogenous variables either with instrumented actual values or with forecast survey data applying the method of gottfries and persson empirical examinations of the information sets of economic agents quarterly journal of economics 103 251 259 i show how to augment these methods with actual future values of the endogenous variables to improve statistical efficiency the method is illustrated with an application to the us hybrid new keynesian phillips curve where traditional lagged instruments and the median forecast from the survey of professional forecasters both appear to miss significant information used by price setters so that forecast pooling with actual values improves the statistical fit to inflation

regime changes in international real interest rates are they a monetary phenomenon in this paper we use the bai and perron 1998 2001 2003 methodology to test for multiple structural breaks in the mean real interest rate for 13 industrialized countries we find extensive evidence of structural breaks in the mean real interest rate for all 13 countries in an attempt to explain the breaks in international real interest rates we also test for multiple structural breaks in the mean inflation rate for the 13 countries once again we find extensive evidence of structural breaks in the mean inflation rate for all of the countries interestingly the breaks in inflation rates and real interest rates often coincide with increases decreases in the mean inflation rate as we move from one regime to the next typically associated with decreases increases in the mean real interest rate

pre announcement and timing the effects of a government expenditure shock abstract an econometric strategy to identify a pre announced fiscal policy shock is proposed i show that the reduced form innovations can be recovered by estimating a vector moving average model using the kalman filter the structural effects are identified exploiting the shock s pre announced nature which leads to potentially different signs of the responses of some endogenous variables during the announcement and after the realization of the shock i illustrate my strategy by identifying a pre announced shock to government consumption expenditures i find that the response of private consumption is significantly negative on impact rises and becomes significantly positive two quarters after the realization of the policy shock

modelling the impacts of a carbon emission differentiated vehicle tax system on co2 emissions intensity from new vehicle purchases in ireland abstract the increasing awareness of the effects of climate change on the environment and the economic pressure on oil supply has focused international attention on reducing co 2 emissions and energy usage across all sectors in order to meet their kyoto protocol commitments and in line with european union policy the irish government has introduced a carbon based tax system for new vehicles purchased from the 1st of july 2008 this new legislation aims to reduce carbon emissions in the transport sector a sector which is responsible for a significant proportion of both this paper presents the results of the development calibration and application of a car choice model which predicts the changes in co 2 emissions intensity from new vehicle purchases as a result of the changes in vehicle tax policy and fuel price in ireland the model also predicts the impact of such changes on tax revenue for the irish government and the changes in the split between the number of diesel and petrol vehicles purchased the investigation found that the introduction of these new carbon based taxes in ireland will result in a reduction of 3 6 3 8 in co 2 emissions intensity and a reduction in annual tax revenue of 191 m

can futures market data be used to understand the behavior of real interest rates this paper examines whether futures market data can be used to understand the behavior of real interest rates several ways of examining the data indicate that futures market data are not particularly informative about real interest rates not only does this evidence cast some doubt on results in previous research that make use of futures market data to draw inferences about real interest rates but it also indicates that future research on real interest rates may need to turn to a different line of attack understanding the behavior of real interest rates is a central issue in financial economics in previous research on this topic several approaches have been used to measure real interest rates in one approach real interest rates have been calculated by subtracting survey data on inflation expectations such as the livingston data from nominal interest rates the problem with survey based measures of real interest rates is that they are only as good as the survey measure of inflation expectations and there may be little incentive for the survey respondents to answer accurately an even more telling criticism of survey based measures often ignored in the literature is that the behavior of market expectations in driven by economic agents ai the margin who are eliminating unexploited profit opportunities market expectations are unlikely therefore to be well measured by the average expectations of survey respondents 2 because of doubts about survey based measures of real interest rates other

the time varying effect of oil price shocks on euro area exports abstract in this paper we provide novel evidence on changes in the relationship between the real price of oil and real exports in the euro area by combining robust predictions on the sign of the impulse responses obtained from a theoretical model with restrictions on the slope of the oil demand and oil supply curves we identify oil supply and foreign productivity shocks in a time varying var with stochastic volatility we find that from the 1980s onwards the relationship between oil prices and euro area exports has become less negative conditional on oil supply shortfalls and more positive conditional on foreign productivity shocks using the theoretical model we show that our empirical findings can be accounted for by i stronger trade relationship between the euro area and emerging economies ii a decrease in the share of oil in production and iii increased competitive pressures in the product market

the fisher hypothesis a critique of recent results and some new evidence the fisher hypothesis 5 that nominal interest rates should respond point for point to changes in the expected inflation rate while theoretically appealing has had limited success in explaining actual interest rate movements most empirical work has shown that net after tax nominal interest rates are not as sensitive to changes in expected inflation as the hypothesis suggests they should be more troublesome still are the results of two recent studies carmichael and stebbing 3 4 hereafter cs and amsler 1 turn the fisher hypothesis on its head by demonstrating that net nominal yields on financial assets do not respond at all to changes in the expected inflation rate rather the net real yield on these assets falls point for point with increases in the expected inflation rate

do tfp and the relative price of investment share a common i 1 component abstract results from cointegration tests clearly suggest that tfp and the relative price of investment rpi are not cointegrated evidence on the alternative possibility that they may nonetheless contain a common i 1 component generating long horizon co variation between them crucially depends on the fact that i structural breaks are or are not allowed for and ii the precise nature and timing of such breaks not allowing for breaks evidence points towards the presence of a common component inducing positive long horizon covariation which is compatible with the notion that the technology transforming consumption goods into investment goods is non linear and the rpi is also impacted upon by neutral shocks allowing for breaks evidence suggests that long horizon covariation is either nil or negative assuming for illustrative purposes that the two series contain a common component inducing negative long horizon covariation evidence based on structural vars shows that this common shock i plays an important role in macroeconomic fluctuations explaining sizeable fractions of the forecast error variance of main macro series and ii generates disinflationary booms characterized by transitory increases in hours and decreases in inflation

fails to deliver short selling and market quality we investigate the aggregate market quality impact of equity shares that fail to deliver hereafter ftds for a sample of 1 492 nyse stocks over a 42 month period from 2005 to 2008 greater ftds lead to higher liquidity and pricing efficiency and their impact is similar to our estimate of delivered short sales furthermore during the operative period of a security and exchange commission sec order mandating stock borrowing prior to short sales the securities affected display relatively lower liquidity and higher pricing errors finally we do not find any evidence that ftds caused price distortions or the failure of financial firms during the 2008 financial crisis

drift and breaks in labor productivity abstract we use endogenous break tests and the stock watson tvp mub methodology to investigate changes in the equilibrium rate of growth of labor productivity in the u s the eurozone the u k australia and japan since wwii results for the u s well capture the conventional wisdom of a golden era of high productivity growth the 1950s and 1960s a marked deceleration starting from the beginning of the 1970s and a strong growth resurgence starting from mid 1990s results for the eurozone point towards a deceleration since the early 1980s with the equilibrium rate of growth of output per hour falling to 0 9 in 2004 4

breaking trends and the money output correlation this paper examines the impact on the money output correla tion of a univariate specification that allows time series to be characterized as stationary around a broken trend function though pretesting suggests that u s real output industrial production can be described as broken trend stationary this result has only limited impact on the money output correlation before 1985 there is a strong granger causal relationship between money and broken detrended output but not first differenced output even when different short term interest rates are used as regres sors however after 1985 this relationship weakens significantly whether or not one determines that output has a unit root

investigating inflation persistence across monetary regimes under inflation targeting estimates of the indexation parameter in hybrid new keynesian phillips curves are either equal to zero or very low in the united kingdom canada sweden and new zealand analogous results hold for the euro area under the european monetary union and for switzerland under the new monetary regime under stable regimes with clearly defined nominal anchors inflation appears to be purely forward looking these results question the notion that the intrinsic inflation persistence found in post wwii u s data is structural in the sense of lucas carnegie rochester conference series on public policy 1 1976 19 46 and suggest that hardwiring inflation persistence in macroeconomic models is potentially misleading

the quest for prosperity without inflation abstract in recent years activist monetary policy rules responding to inflation and the level of economic activity have been advanced as a means of achieving effective output stabilization without inflation advocates of such policies suggest that their flexibility may yield substantial stabilization benefits while avoiding the excesses of overzealous discretionary fine tuning such as is thought to characterize the experience of the 1960s and 1970s in this study i present evidence suggesting that these conclusions are misguided using an estimated model i show that when informational limitations are properly accounted for activist policies would not have averted the great inflation but instead would have resulted in worse macroeconomic performance than the actual historical experience the problem can be attributed in large part to the counterproductive reliance of these policies on the output gap the analysis suggests that the dismal economic outcomes of the great inflation may have resulted from an unfortunate pursuit of activist policies in the face of bad measurement specifically overoptimistic assessments of the output gap associated with the productivity slowdown of the late 1960s and early 1970s

financial and fiscal interaction in the euro area crisis this time was different abstract this paper highlights the anomalous characteristics of the euro area twin crises by contrasting the aggregate macroecosnomic dynamics in the period 2009 2013 with the business cycle fluctuations of the previous decades we report three novel stylised facts first the contraction in output was marked by an anomalous downfall in private investment and an increase in households savings while consumption and unemployment followed their historical relation with gdp second households and financial corporations debts and house prices deviated from their pre crisis trends while non financial corporations debt followed historical regularities third the jumps in the public deficit gdp and debt gdp ratios in 2008 2009 were unprecedented and so was the fiscal consolidation that followed our analysis points to the financial nature of the crisis as a likely explanation for these facts importantly the anomalous increase in public debt is in large part explained by extraordinary measures in support of the financial sector which show up in the stock flow adjustments and reveal a keyinteraction between the fiscal and the financial sectors

the new econometrics of structural change dating breaks in u s labor productivity we have seen the emergence of three major innovations in the econometrics of structural change in the past fifteen years 1 tests for a structural break of unknown timing 2 estimation of the timing of a structural break and 3 tests to distinguish unit roots from broken time trends these three innovations have dramatically altered the face of applied time series econometrics in this paper we review these three innovations and illustrate their application through an empirical assessment of u s labor productivity in the manufacturing durables sector

sources of variation in international real interest rates this paper analyses the effects of inflation on ex post real interest rates in an international framework a dynamic factor model is estimated in which real interest rates are influenced by real interest and inflation factors that are common to all the countries and by country specific factors we find that the source of domestic inflation is an important determinant of the effect of inflation on real interest rates a common inflation factor has a negative effect on ex post real interest rates lending support to a form of the mundell tobin effect in international real interest rates and that a country specific inflation factor tends to have a positive effect

distinguished lecture on economics in government the new economy post mortem or second wind there was an acceleration of u s productivity after 1995 investment in information technology hardware and software contributed importantly to this but was not its sole cause in part heavy it investment perhaps overinvestment was the result of the booming economy and cheap capital besides it the expansion of productive firms boosted productivity together with the competitive pressure this put on other firms to innovate and improve productivity growth has been surprisingly strong in 2001 and the likely trend for the future is in the range of 2 2 to 2 7 percent a year the economy should get a second wind

greening the vehicle fleet norway s co2 differentiated registration tax abstract in 2007 norway established its vehicle registration tax linked to vehicle co2 intensities in 2009 the tax was modified to a feebate structure but maintained its link to co2 intensities using a panel dataset to exploit the quasi experimental tax reforms we estimate that a 1000 nok 125 usd tax increment reduces new vehicle sales by 1 06 1 58 this result yields an elasticity of average co2 intensity to co2 price implied by the tax of 0 06 with a pass through of the tax to car prices of 88 the resulting elasticity of average co2 intensity to average car price is 0 53 thus the tax significantly shifts consumers toward lower emission vehicles our counterfactual simulations suggest that high emission vehicle segments lose market shares and become less co2 intensive while low emission vehicle segments gain market shares

selection on observed and unobserved variables assessing the effectiveness of catholic schools in this paper we measure the effect of catholic high school attendance on educational attainment and test scores because we do not have a good instrumental variable for catholic school attendance we develop new estimation methods based on the idea that the amount of selection on the observed explanatory variables in a model provides a guide to the amount of selection on the unobservables we also propose an informal way to assess selectivity bias based on measuring the ratio of selection on unobservables to selection on observables that would be required if one is to attribute the entire effect of catholic school attendance to selection bias we use our methods to estimate the effect of attending a catholic high school on a variety of outcomes our main conclusion is that catholic high schools substantially increase the probability of graduating from high school and more tentatively attending college we find little evidence of an effect on test scores

negative publicity and catholic schools i introduction catholic education makes up a large part of the united states k 12 educational system catholic schools educate over one third of all private school students more elementary and secondary students than all other religious schools combined national center for education statistics nces 2007 however catholic education is becoming less prevalent between 1990 and 2007 the number of catholic schools decreased by 14 from 8 719 to 7 498 while enrollment declined by 7 from 2 498 870 to 2 320 651 1 the mainstream media has covered this trend beginning with closings in the early 1990s foderaro 1990 private schools enroll 11 of elementary and secondary school students 39 of private school students enroll in catholic schools 2 catholic schools historically have served a predominantly urban minority population with some success research generally finds modest gains in educational attainment particularly for minority students e g altonji et al 2005 evans and schwab 1995 neal 1997 there is evidence that catholic schools raise student academic achievement and reduce adolescent risky behaviors figlio and ludwig 2000 figlio and stone 2000 3 the current decline in catholic schooling reflects diminished opportunities for students to enroll in alternatives to public schools this decline is particularly troubling for the low income urban minority students who have particularly benefited from catholic schools in the past neal 1997 the decline in private schooling options also lowers the level of competition among schools the decrease in competition may worsen the outcomes of public school students hoxby 1994 we consider potential explanations for the decline in catholic schooling in the united states changing demographics changing income levels and public awareness of sexual abuse and allegations immigration into and within the united states particularly of the traditionally catholic hispanic population likely affected demand for catholic schooling o keefe 1996 suggests that falling income per capita near existing catholic schools led to school closings further the negative publicity from the sexual abuse crisis in the catholic church may have impacted the availability of and demand for catholic schooling using diocese level panel data on catholic schooling we empirically examine the importance of each of these factors we develop two proxy measures of negative publicity based on the press coverage and on plausibly public notifications of abuse allegations we find that negative publicity is associated with a reduction in the availability of catholic schools however its effect is small allegations related to the abuse cases account for about 5 of the decline in catholic schools changing demographics particularly increases in the hispanic population explain a larger proportion of the current decline in catholic schooling ii an overview of catholic school enrollment and catholic schools in the united states the catholic church is organized into dioceses and archdioceses each administered by a bishop or archbishop there are 175 of these in the united states with each state and the district of columbia having at least one dioceses for the most part follow county lines texas with 14 is the state that has the most dioceses the average state has approximately 3 5 dioceses catholic schools tend to be operated with financial backing from the local diocese in combination with revenue from tuition and direct donations diocesan support ranges from a low of around 5 of school funding coming from dioceses in the south and west to a high of about 50 in the midwest gero and meitler 2003 figure 1 presents the percent of school aged children enrolled in catholic schools and the number of catholic schools for 1990 to 2007 4 the number of catholic schools declined in the early 1990s the decline slowed in the mid 1990s and accelerated again around 2004

are there rational bubbles in foreign exchange markets evidence from an alternative test abstract this paper employs the kalman filter technique to estimate and test for stochastic bubbles for exchange rates between the us dollar and the british pound the japanese yen and the deutsche mark i find no significant evidence of bubbles my results are in sharp contrast with previous findings on exchange rate bubble testing and cast some doubt on those claims that the dollar exchange rates were driven by speculative bubbles in the post bretton woods period

are expectations of inflation rational or is variation of the expected real interest rate unpredictable abstract the joint hypothesis developed and tested in this paper is that the nominal interest rate is a rational expectation of the real interest rate plus the inflation rate and that variation of the expected real interest rate is unpredictable on the basis of information used in the test this test is applied to quarterly data on three month united states treasury bills of 1954 to 1973 the information used in the tests includes besides past interest rates and inflation rates past growth rates of the source base the money supply and real gnp some of the tests allow for a positive marginal tax rate which changes the results little the hypothesis is generally consistent with the data which provides support for the proposition that predictable changes of the money supply do not affect expected real interest rates over periods as short as a quarter

estimation of unobserved expected monthly inflation using kalman filtering hamilton developed a technique for estimating financial market expectations of inflation based on the observed time series properties of interest rates and inflation the technique is based on a state space representation derived from an underlying vector autoregressive process of the expected real interest rate and the expected inflation rate on lagged expectations and lagged values of the observed treasury bill rate and the actual inflation rate this article extends this work in two ways first we use monthly data since the quarterly data used by hamilton may obscure many interesting movements especially for determining the role of inflationary expectations in stock price movements and this is one of our primary interests second we employ an alternative method developed by burmeister and wall for estimating the parameters of the model and this method leads to a different identification proof both approaches share the use of the kalman filter to estimate the unobserved variables in this case e

technology utilization and inflation what drives the new keynesian phillips curve we argue that the new keynesian phillips curve literature has failed to deliver a convincing measure of real marginal costs we start from a careful modeling of optimal price setting allowing for nonunitary factor substitution nonneutral technical change and time varying factor utilization rates this ensures the resulting real marginal cost measures match volatility reductions and level changes witnessed in many u s time series the cost measure comprises conventional countercyclical cost elements plus procyclical and covarying utilization rates although procyclical elements seem to dominate the components of real marginal cost components are becoming less cyclical over time incorporating this richer driving variable produces more plausible price stickiness estimates than otherwise and suggests a more balanced weight of backward and forward looking inflation expectations than commonly found our results challenge existing views of inflation determinants and have important implications for modeling inflation in new keynesian models

are the costs of reducing greenhouse gases from passenger vehicles negative energy models suggest that the costs of reducing carbon emissions from transportation are high relative to those for other sectors this paper discusses why taxes or equivalent permit systems to reduce passenger vehicle emissions produce large net benefits rather than costs when account is taken of a their impact on reducing other highway externalities besides carbon and b interactions with the broader fiscal system both of these considerations also strengthen the case for a tax based approach over fuel economy regulation while fiscal considerations strengthen the case for taxes over grandfathered emissions permits the paper also comments on the practical relevance of automobile fuel taxes or their policy equivalents to broader legislation intended to mitigate climate change

how responsive is saudi new vehicle fleet fuel economy to fuel and vehicle price policy levers abstract this paper investigates the drivers of recent improvements in saudi arabia s fleet fuel economy for new vehicles including passenger cars and light duty trucks vehicle choice models are estimated using both aggregate new vehicle sales data and disaggregate new vehicle buyer survey data the estimated models are used to simulate counterfactual policy scenarios simulation results suggest that the saudi gasoline price elasticity of demand for new vehicle fuel economy decreased slightly over recent years but it is still more elastic than that of the united states moreover the increase in domestic gasoline prices between 2014 and 2016 accounted for 42 of the increase in estimated new vehicle fleet fuel economy over that period finally the estimated elasticities and thus policy sensitivities vary by income and household size a revenue neutral household income and size based feebate policy could be more progressive than a gasoline price increase for improving the new vehicle fleet fuel economy

inflation real returns and capital investment we find evidence for the hypothesis of mundell 1963 and tobin 1965 that the expected real return component of interest rates is negatively related to the expected inflation component in the mundell tobin model the variation in expected real returns is caused by the variation in expected inflation our evidence suggests however that the variation in expected real returns is more fundamentally an outcome of the capital expenditures process equilibrium expected real returns vary directly with capital expenditures in order to induce equilibrium allocations of resources between consumption and investment this positive relation between expected real returns and real activity which comes out of the real sector combines with a negative relation between expected inflation and real activity which is traced to the monetary sector thus inducing the negative relation between expected inflation and expected real returns predicted by mundell and tobin but explained in terms of a model much different from theirs

understanding the fisher equation it is argued that univariate long memory estimates based on ex post data tend to underestimate the persistence of ex ante variables and hence that of the ex post variables themselves because of the presence of unanticipated shocks whose short run volatility masks the degree of long range dependence in the data empirical estimates of long range dependence in the fisher equation are shown to manifest this problem and lead to an apparent imbalance in the memory characteristics of the variables in the fisher equation evidence in support of this typical underestimation is provided by results obtained with inflation forecast survey data and by direct calculation of the finite sample biases to address the problem of bias the paper introduces a bivariate exact whittle bew estimator that explicitly allows for the presence of short memory noise in the data the new procedure enhances the empirical capacity to separate low frequency behaviour from high frequency fluctuations and it produces estimates of long range dependence that are much less biased when there is noise contaminated data empirical estimates from the bew method suggest that the three fisher variables are integrated of the same order with memory parameter in the range 0 75 1 since the integration orders are balanced the ex ante real rate has the same degree of persistence as expected inflation thereby furnishing evidence against the existence of a fractional cointegrating relation among the fisher variables and correspondingly showing little support for a long run form of fisher hypothesis copyright 2004 john wiley sons ltd

religiosity and state welfare abstract the catholic sex abuse scandals reduced both membership and religiosity in the catholic church because government spending on welfare may substitute for the religious provision of social services we consider whether this plausibly exogenous decline in religiosity affected several measures of the public taste toward government and spending on welfare between 1990 and 2008 in places where there were more scandals individuals state a preference for less government provision of social services in contrast a higher level of abuse is also associated with an increase in voting for democratic candidates for president state legislatures and the us house of representatives and an increase in per capita government welfare spending although this increase is insufficient to replace the decrease in catholic provided charity

new vehicle fuel economy in the uk impact of the recession and recent policies interests in vehicle fuel economy have increased in the past few years with the implementations of more stringent cafe standard in usa and mandatory carbon emission standard in the eu we seek to understand the effects of recent policies such as restructuring of vehicle excise duties and eu standard on new vehicle fuel economy in the uk in the past few years there have been substantial fluctuations in income and fuel prices offering an interesting testing ground to understand their impact on the demand for fuel economy in vehicles we use a monthly dataset to find that the emission standard is the largest driver for fuel economy improvements in recent years also contrary to some recent findings in europe and in uk we find that income has an effect and that the recession had some role in improving the fuel economy the effects of fuel prices were relatively small restructuring of the ved also improved new vehicle fuel economy in the uk but the scrappage scheme had no significant effect results indicate that both supply and demand side policies are effective in improving fuel economy although quantitatively the emission standard appears more effective due to its stringency it is also important to consider the effects of income while devising demand side policies

rational expectations econometric analysis of changes in regime an investigation of the term structure of interest rates abstract this paper is of interest both for its methodological contribution of new tools for analyzing rational expectations models and for its substantive conclusions concerning the term structure of interest rates during the monetary experiment of october 1979 the paper studies systems subject to changes in regime interpreted here as occasional discrete shifts in the parameters governing the time series behavior of exogenous economic variables the specification is shown to be quite tractable both theoretically and empirically the technique is used to analyze yields on three month treasury bills and ten year treasury bonds during 1962 to 1987 a constant parameter linear model for short term rates is shown to be inconsistent both with the univariate time series properties of short rates and with the observed bivariate relation between long and short rates under the expectations hypothesis of the term structure an alternative nonlinear model that admits the possibility of changes in regime affords a much better description of the univariate process for short rates moreover the cross equation restrictions implied by the expectations hypothesis of the term structure are consistent with the nonlinear specification indeed the residuals of the restricted relation have a standard error of only 0 8 basis points this is a third less than that of a completely unrestricted linear regression of long rates on short rates and compares with an unconditional standard deviation of long rates of 142 basis points i conclude that once the recognition by bond traders of changes in regime is taken into account the expectations hypothesis of the term structure of interest rates holds up fairly well for these data

international evidence on time variation in trend labor productivity growth this paper provides international evidence on time variation in trend productivity growth based on the dataset for hours worked constructed by ohanian raffo 2012 applying both the endogenous break tests of bai perron 1998 2003 and the stock watson 1996 1998 tvp mub methodology substantial evidence of time variation in trend productivity growth is detected for most countries for either japan or countries belonging to the eurozone evidence points towards a significant growth decline over the last several decades weaker evidence is reported for the united states for which the 1990 s productivity acceleration is estimated to have been overall mild and of a temporary nature

the simple economics of motor vehicle pollution a case for fuel tax the volume of pollution produced by an automobile is determined by driver s behavior along three margins i vehicle selection ii kilometers driven and iii on road fuel economy the first two margins have been studied extensively however the third has received scant attention how significant is this intensive margin what would be the optimal policies when it is taken into account the paper develops and analyzes a simple model of the technical and behavioral mechanisms that determine the volume emissions produced by a car the results show that an optimal fuel tax would provide drivers with appropriate incentives along all three margins and that only public information is needed for a fuel tax to be set optimally in contrast an optimal distance tax would require private information lastly relative to the optimal fuel tax a simple uniform fuel tax is shown to be progressive thus being already deployed worldwide a uniform fuel tax is an attractive second best policy these findings should be accounted for when designing new mechanisms to alleviate motor vehicle pollution

investigating time variation in the marginal predictive power of the yield spread abstract we use bayesian time varying parameters vars with stochastic volatility to investigate changes in the marginal predictive content of the yield spread for output growth in the united states and the united kingdom since the gold standard era and in the eurozone canada and australia over the post wwii period overall our evidence does not provide much support for either of the two dominant explanations why the yield spread may contain predictive power for output growth the monetary policy based one and harvey s 1988 the real term structure and output growth journal of financial economics 22 305 333 real yield curve one instead we offer a new conjecture

vancouver s gasoline price wars an empirical exercise in uncovering supergame strategies this paper uses a unique data set to determine which dynamic model of tacit collusion best describes behaviour in a particular industry the area investigated is a region of the vancouver british columbia retail gasoline market players are service station managers who compete daily firms choose price in each period using strategies that depend on prices chosen in the previous period periodically unanticipated demand shocks precipitate price wars when shocks occur the firms in the market must determine the new demand conditions and adjust their strategies from an econometric point of view slopes of intertemporal reaction functions are latent variables the resulting system of equations with time varying parameters is estimated via the kalman filter different repeated game oligopoly models correspond to different transition matrices for the latent variables the models can thus be assessed in terms of their power to explain firm behaviour in this market

a meta analysis of the price elasticity of gasoline demand a sur approach abstract automobile gasoline demand can be expressed as a multiplicative function of fuel efficiency mileage per car and car ownership this implies a linear relationship between the price elasticity of total fuel demand and the price elasticities of fuel efficiency mileage per car and car ownership in this meta analytical study we aim to investigate and explain the variation in empirical estimates of the price elasticity of gasoline demand a methodological novelty is that we use the linear relationship between the elasticities to develop a meta analytical estimation approach based on a seemingly unrelated regression sur model with cross equation restrictions this approach enables us to combine observations of different elasticities and thus increase our sample size furthermore it allows for a more detailed interpretation of our meta regression results the empirical results of the study demonstrate that the sur approach leads to more precise results i e lower standard errors than a standard meta analytical approach we find that with mean short run and long run price elasticities of 0 34 and 0 84 respectively the demand for gasoline is not very price sensitive both in the short and the long run the impact of a change in the gasoline price on demand is mainly driven by responses in fuel efficiency and mileage per car and to a slightly lesser degree by changes in car ownership furthermore we find that study characteristics relating to the geographic area studied the year of the study the type of data used the time horizon and the functional specification of the demand equation have a significant impact on the estimated value of the price elasticity of gasoline demand

cost of capital to the hospital sector this paper provides estimates of the cost of equity and debt capital to for profit and non profit hospitals in the u s for the years 1972 83 the cost of equity is estimated using alternatively the capital asset pricing model and arbitrage pricing theory we find that the cost of equity capital using either model substantially exceeded anticipated inflation the cost of debt capital was much lower accounting for the corporate tax shield on debt and capital paybacks by cost based insurers lowered the net cost of capital to hospitals

uncovering financial markets beliefs about inflation targets this paper exploits the term structure of interest rates to develop testable economic restrictions on the joint process of long term interest rates and inflation when the latter is subject to a targeting policy by the central bank in an empirical application to the canadian inflation target zone results indicate that financial markets perceive the band to be of approximately the same width as announced but asymmetrically distributed around the official target this finding suggests that in practice the monetary authority might attach different weights to positive and negative inflation deviations from the target copyright 2000 john wiley sons ltd

real interest rates and inflation an ex ante empirical analysis we develop a method of measuring ex ante real interest rates using prices of index and nominal bonds employing this method and newly available data we directly test the fisher hypothesis that the real rate of interest is independent of inflation expectations we find a negative correlation between ex ante real interest rates and expected inflation this contradicts the fisher hypothesis but is consistent with the theories of mundell and tobin darby and feldstein and stulz we also find that nominal interest rates include an inflation risk premium that is positively related to a proxy for inflation uncertainty

an examination of the relationship between australian industry equity returns and expected inflation this paper analyses the relationship between inflation and equity returns in australia over the period january 1974 to march 1996 analysis is based on monthly and quarterly data using value weighted equity indices at both the aggregate market and industry level three price indices the consumer price index cpi quarterly and the manufactured materials used index mmu and the manufacturing articles produced index map both monthly and quarterly are used to measure inflation results provide little evidence of the statistically significant negative relationship observed in the us for the full study period analysis is also conducted on three subperiods monetary targeting july 1976 january 1985 checklist approach february 1985 december 1989 and anti inflation january 1990 march 1996 at the market level the anti inflation subperiod does provide some evidence of a negative relationship between inflation and equity returns though statistical significance is not apparent with quarterly tim

the impact of tax reform on new car purchases in ireland we examine the impact of recent tax reforms in ireland on private car transport and its greenhouse gas emissions a carbon tax was introduced on fuels and purchase vehicle registration and ownership motor taxes were switched from engine size to potential emissions we use a demographic model of the car stock by age size and fuel and a car purchase model that reflects the heterogeneous distribution of mileage and usage costs across various engine sizes the model shows a dramatic shift from petrol to diesel cars particularly for large engines the same pattern is observed in the latest data on car sales this has a substantial impact on tax revenue as car owners shift to the lower tax rates the tax burden has shifted from car ownership to car use and that the overall tax burden on private car transport falls as diesel engines are more fuel efficient than petrol engines carbon dioxide emissions fall modestly or if we consider the rebound effect of travel costs on mileage minimally from the perspective of the revenue the costs per tonne of carbon dioxide avoided are very high

finishing high school and starting college do catholic schools make a difference in this paper we consider two measures of the relative effectiveness of public and catholic schools finishing high school and starting college these measures are potentially more important indicators of school quality than standardized test scores in light of the economic consequences of obtaining more education single equation estimates suggest that for the typical student attending a catholic high school raises the probability of finishing high school or entering a four year college by thirteen percentage points in bivariate probit models we find almost no evidence that our single equation estimates are subject to selection bias
