are contributions of time and money substitutes or complements abstractthis article empirically investigates the relationship between donations of time and money using canadian tax policy reforms that changed the tax price of charitable donations the 1988 reform where a charitable tax deduction was converted to a credit and the 2000 reform in provincial income taxes provide tax price variations plausibly exogenous to individuals unobserved heterogeneity our estimates on cross price effects imply that individuals make more time donations as the tax price of charitable donations increases and hence money and time donations are substitutes as some theories would imply this contrasts with earlier findings using cross sectional data

bond market exposures to macroeconomic and monetary policy risks i provide empirical evidence of changes in the u s treasury yield curve and related macroeconomic factors and investigate whether the changes are brought about by external shocks monetary policy or by both to explore this i characterize bond market exposures to macroeconomic and monetary policy risks using an equilibrium term structure model with recursive preferences in which inflation dynamics are endogenously determined in my model the key risks that affect bond market prices are changes in the correlation between growth and inflation and changes in the conduct of monetary policy using a novel estimation technique i find that the changes in monetary policy affect the level of bond yields through their effect on expected inflation while the changes in the correlation between growth and inflation affect both the level as well as the volatility of bond yields consequently the changes in the correlation structure are the main contributor to bond risk premia and to bond market volatility the time variations within a regime and risks associated with moving across regimes lead to the failure of the expectations hypothesis and to the excess bond return predictability regression of cochrane and piazzesi 2005 as in the data

interest rate caps smile too but can the libor market models capture the smile using 3 years of interest rate caps price data we provide a comprehensive documentation of volatility smiles in the caps market to capture the volatility smiles we develop a multifactor term structure model with stochastic volatility and jumps that yields a closed form formula for cap prices we show that although a three factor stochastic volatility model can price at the money caps well significant negative jumps in interest rates are needed to capture the smile the volatility smile contains information

sources of intra industry wage dispersion how much do employers matter observed human capital explains less than half of wage variation in bls industry wage surveys establishment based wage differentials controlling for occupation account for 20 70 percent of intra industry wage variation this corresponds to a standard deviation in wages of 14 percent of the mean almost as large as interindustry wage variation investigation suggests that establishment wage differentials are not random variations or returns to usual measures of human capital

why has u s inflation become harder to forecast we examine whether the u s rate of price inflation has become harder to forecast and to the extent that it has what changes in the inflation process have made it so the main finding is that the univariate inflation process is well described by an unobserved component trend cycle model with stochastic volatility or equivalently an integrated moving average process with time varying parameters this model explains a variety of recent univariate inflation forecasting puzzles and begins to explain some multivariate inflation forecasting puzzles as well

a non radial dea approach to measuring environmental performance data envelopment analysis dea has gained great popularity in environmental performance measurement because it can provide a synthetic standardized environmental performance index when pollutants are suitably incorporated into the traditional dea framework past studies about the application of dea to environmental performance measurement often follow the concept of radial efficiency measures in this paper we present a non radial dea approach to measuring environmental performance which consists of a non radial dea based model for multilateral environmental performance comparisons and a non radial malmquist environmental performance index for modeling the change of environmental performance over time a case study of oecd countries using the proposed non radial dea approach is also presented it is found that the environmental performance of oecd countries as a whole has been improved from 1995 to 1997

tips from tips the informational content of treasury inflation protected security prices treasury inflation protected securities tips are frequently thought of as risk free real bonds using no arbitrage term structure models we show that tips yields exceeded risk free real yields by as much as 100 basis points when tips were first issued and up to 300 basis points during the 2007 2008 financial crisis this spread predominantly reflects the poorer liquidity of tips relative to nominal treasury securities other factors including the indexation lag and the embedded deflation protection in tips play a much smaller role ignoring this spread also significantly distorts the informational content of tips break even inflation a widely used proxy for expected inflation

quantifying the uncertainty about the fit of a new keynesian pricing model abstract recent studies by gali and gertler 1999 inflation dynamics a structural econometric analysis journal of monetary economics 44 195 222 and sbordone 2002 prices and unit labor costs testing models of pricing journal of monetary economics 49 265 292 conclude that a theoretical inflation series implied by a forward looking new keynesian pricing equation fits post 1960 u s inflation closely their theoretical inflation series is conditional on i a reduced form forecasting process for real marginal cost and ii the calibration of the pricing equation the present paper shows that both of these determinants are surrounded by considerable uncertainty when quantifying the impact of this uncertainty on theoretical inflation we can no longer say whether the forward looking pricing equation explains observed inflation dynamics very well or very poorly

empirical evidence on inflation expectations in the new keynesian phillips curve abstract we review the main identification strategies and empirical evidence on the role of expectations in the new keynesian phillips curve paying particular attention to the issue of weak identi

slacks based efficiency measures for modeling environmental performance we develop two slacks based efficiency measures for modeling environmental performance on the basis of environmental dea technology of the two measures one is a composite index with a higher discriminating power for modeling economic environmental performance and the other can be used to estimate the impacts of environmental regulations we apply the proposed measures to model the co2 emissions of 30 oecd countries from 1998 to 2002 and present the results obtained

elusive persistence wage and price rigidities the new keynesian phillips curve and inflation dynamics abstract we review the main new keynesian inflation equations that have arisen as a result of aggregation from individual firms price rigidities we find that on the whole they cannot account for inflation persistence a key feature of the empirical dynamics of inflation and with important policy implications the only exceptions seem to be when indexation is allowed in price setting or when price stickiness is combined with wage rigidity and staggering

testing for indeterminacy an application to u s monetary policy reply this paper considers a prototypical new keynesian model in which the equilibrium is undetermined if monetary policy is passive the likelihood based estimation of dynamic equilibrium models is extended to allow for indeterminacies and sunspot fluctuations we construct posterior weights for the determinacy and indeterminacy region of the parameter space and estimates for the propagation of fundamental and sunspot shocks according to the estimated model u s monetary policy post 1982 is consistent with determinacy whereas the pre volcker policy is not we find that before 1979 indeterminacy substantially altered the propagation of shocks

gmm estimation of the new phillips curve abstract this paper applies test statistics developed by stock and wright econometrica 68 2000 1055 to examine the two specifications of the new keynesian phillips curve in gali and gertler journal of monetary economics 44 1999 195 the new test statistics demonstrate the inadequacy of conventional gmm methodology by indicating two features that are neglected by gali and gertler observational equivalence in the baseline model and weak identification in the hybrid model

does it pay for women to volunteer this article estimates the economic and noneconomic returns to volunteering for prime aged women estimates of a dcdp model indicate that an extra year of volunteer experience increases wage offers by 8 5 in future part time work and by 2 6 in future full time work on average working for free increases lifetime earnings by 16 7 the economic returns to volunteering are more important than the noneconomic returns in increasing lifetime utility the model also reveals an adverse selection mechanism into volunteering that helps explain why reduced form regressions of the returns to working for free will likely be downward biased

the new keynesian phillips curve revisited abstract several authors have questioned the evidence claimed by gali and gertler 1999 and gali et al 2001 that a hybrid version of the new keynesian phillips curve approximates european and us inflation dynamics quite well we re examine the evidence using the vector autoregressive framework and likelihood based methods paying particular attention to the stationary and nonstationary and possibly cointegrated nature of variables involved our results show that the exact as well as the inexact form of the hybrid nkpc are clearly at odds with the european data on the other hand gali and gertler 1999 finding that the inexact hybrid nkpc is a good first approximation to the us inflation dynamics seems less at odds with the data however the assumption of the model that the stochastic term forms a sequence of innovations may be problematic as we find indication of autocorrelation in the estimated residuals the exact form of the hybrid nkpc is firmly rejected by the us data

deflation risk in the euro area and central bank credibility abstract we analyze a new option based indicator of market perceptions of euro area deflation risks we find that during 2010 2015 long term deflation risks became slightly more sensitive to oil price changes and inflation surprises suggesting a subtle weakening in anchoring

carbon emissions performance in logistics at the city level the importance of good performance in the logistics industry contributing towards a low carbon economy is widely recognised however there are few studies on carbon emissions performance for the logistics industry especially at the city level therefore this study attempts to analyse the carbon emissions performance of the logistics industry at the city level by examining sixteen cities within yunnan province in particular the data envelopment analysis dea model and malmquist index from both the static and dynamic perspective were explored to further capture the driving factors of the carbon emissions performance in logistics the tobit model was applied to perform regression analysis the results indicate that 1 with regards to static performance two northwest cities nujiang and diqing have reached the technological frontier 2 regarding dynamic performance although six cities have improved the average dynamic logistics carbon emissions performance of all the cities decreases by approximately 5 9 from 2011 to 2015 3 in terms of driving factors the economic development factor is found to be positively and significantly related to static carbon emissions performance whereas others indicate negative and significant relationships

volunteering and life or financial shocks does income and wealth matter volunteering is a dominant social force that signals a healthy state however although the literature on volunteering is extensive knowledge on how life s discontinuities life and financial shocks affect volunteering is limited because most studies work with static cross sectional data to reduce this shortcoming we use longitudinal data from australia hilda that track the same individuals over time to assess how individuals from different income and wealth groups respond to life and financial shocks with respect to volunteering although both income and wealth can act as buffers against life shocks by providing stability and reducing vulnerability which decreases the need to actually change behaviour patterns we observe more heterogeneity than expected and also stickiness at the lowest income levels response delays in post shock volunteering also suggest that volunteering habits may be driven and influenced by strong commitment and motivation that are not shattered by life or financial shocks in fact the amount of time spent volunteering tends to increase after negative income shocks and decrease after positive income shocks

efficient energy saving targets for apec economies abstract energy saving target ratios estr for 17 apec economies during 1991 2000 are computed in a total factor framework all nominal variables are transformed into real variables by the purchasing power parity ppp at the 1995 price level the data envelopment analysis dea approach is used to find the energy saving target est for apec economies without reducing their maximum potential gross domestic productions gdps in each year energy labor and capital are the three inputs while gdp is the single output our major findings are as follows 1 china has the largest est up to almost half of its current usage 2 hong kong the philippines and the united states have the highest energy efficiency 3 the energy efficiency generally increases for apec economies except for canada and new zealand 4 chile mexico and taiwan have significantly improved their energy efficiency in the last 5 years 5 an inverted u shape relation exists between per capita est and per capita gdp 6 estr has a positive relation with the value added percentage of gdp of the industry sector and a negative relation with that of the service sector

the new keynesian phillips curve from sticky inflation to sticky prices the new keynesian phillips curve nkpc model of inflation dynamics based on forward looking expectations is of great theoretical significance in monetary policy analysis empirical studies however often find that backward looking inflation inertia dominates the dynamics of the short run aggregate supply curve this inconsistency is examined by investigating multiple structural changes in the nkpc for the u s between 1960 and 2005 employing both inflation expectations survey data and a rational expectations approximation we find that forward looking behavior plays a smaller role during the high and volatile inflation regime to 1981 than in the subsequent period of moderate inflation providing empirical support for sticky price models over the last two decades a break in the intercept of the nkpc is also identified around 2001 and this may be associated with u s monetary policy in that period

gender role attitudes and the labour market outcomes of women across oecd countries this paper uses data from the world value surveys 1990 1995 1999 to investigate the impact of gender role attitudes and work values on women s labour market outcomes across 25 oecd countries anti egalitarian views are found to display the strongest negative association with female employment rates and the gender pay gap these views are however softening among recent cohorts on the other hand perceptions of women s role as homemakers which are likely formed in youth and linked to religious ideology are more persistent over time they could be implicated in the recent slowdown of the gender convergence in pay finally the unavoidable clash between family values and egalitarian views that takes the form of an inner conflict for many women the so called mother s guilt is another obstacle in the path towards greater gender equality in the labour market copyright 2005 oxford university press

limited information estimation and evaluation of dsge models we advance the proposition that dynamic stochastic general equilibrium dsge models should not only be estimated and evaluated with full information methods these require that the complete system of equations be specified properly some limited information analysis which focuses upon specific equations is therefore likely to be a useful complement to full system analysis two major problems occur when implementing limited information methods these are the presence of forward looking expectations in the system as well as unobservable non stationary variables we present methods for dealing with both of these difficulties and illustrate the interaction between full and limited information methods using a well known model copyright 2009 john wiley sons ltd

inflation expectations real rates and risk premia evidence from inflation swaps this paper develops a model of the term structures of nominal and real interest rates driven by state variables representing the short term real interest rate expected inflation inflation s central tendency and four volatility factors that follow garch processes we derive analytical solutions for nominal bond yields yields on inflation indexed bonds that have an indexation lag and the term structure of expected inflation unlike prior studies the model s parameters are estimated using data on inflation swap rates as well as nominal yields and survey forecasts of inflation the volatility state variables fully determine bonds time varying risk premia and allow for stochastic volatility and correlation between bond yields yet they have small effects on the cross section of nominal yields allowing for time varying volatility is particularly important for real interest rate and expected inflation processes but long horizon real and inflation risk premia are relatively stable

is inflation sticky abstract new keynesian sticky price models predict that monetary policy can affect real variables however they also predict that inflation can be reduced without depressing output or employment in fact bringing down inflation is costly presenting a challenge to the new keynesian model two departures from the new keynesian model predict costly disinflation one assumes sticky inflation rather than sticky prices while the other assumes less than perfectly rational expectations taking into account information from surveys of inflation expectations i find the evidence suggests that inflation is not sticky and that inflation expectations are less than perfectly rational

the tips treasury bond puzzle we show that the price of a treasury bond and an inflation swapped treasury inflation protected securities tips issue exactly replicating the cash flows of the treasury bond can differ by more than 20 per 100 notional treasury bonds are almost always overvalued relative to tips total tips treasury mispricing has exceeded 56 billion representing nearly 8 of the total amount of tips outstanding we find direct evidence that the mispricing narrows as additional capital flows into the markets this provides strong support for the slow moving capital explanation of arbitrage persistence

events that shook the market tick data on the standard and poor s 500 stock index s p 500 futures contract and newswire searches are used to match events to large 1 to 5 minute stock price changes sixty nine events that led to large stock price changes are identified between 1982 and 1999 53 of which are directly or indirectly related to monetary policy many large stock price changes have no events associated with them

modeling undesirable factors in efficiency evaluation abstract data envelopment analysis dea measures the relative efficiency of decision making units dmus with multiple performance factors which are grouped into outputs and inputs once the efficient frontier is determined inefficient dmus can improve their performance to reach the efficient frontier by either increasing their current output levels or decreasing their current input levels however both desirable good and undesirable bad factors may be present for example if inefficiency exists in production processes where final products are manufactured with a production of wastes and pollutants the outputs of wastes and pollutants are undesirable and should be reduced to improve the performance using the classification invariance property we show that the standard dea model can be used to improve the performance via increasing the desirable outputs and decreasing the undesirable outputs the method can also be applied to situations when some inputs need to be increased to improve the performance the linearity and convexity of dea are preserved through our proposal

an open economy new keynesian phillips curve for the u k abstract we estimate a pricing equation or new keynesian phillips curve nkpc obtained from a structural dynamic model of price setting based on rotemberg 1982 sticky prices in the united states journal of political economy 90 6 1187 1211 and extended to capture employment adjustment costs and the openness of the united kingdom this model nests the baseline gali and gertler 1999 inflation dynamics a structural econometric analysis quarterly journal of economics 110 127 159 and sbordone 2002 prices and unit labor costs a new test of price stickiness journal of monetary economics 49 265 292 relationship between inflation and marginal cost in the limiting case of no employment adjustment costs no impact of relative prices of imported inputs on real marginal cost and a constant equilibrium markup our findings indicate that each of our modifications to the baseline nkpc model is important for u k data so that inflation in the u k is explained both by changes in employment and by changes in real import prices in general and real oil prices in particular external competitive pressures also seem to affect u k inflation via their impact on the equilibrium price markup of domestic firms

multilateral productivity comparisons when some outputs are undesirable a nonparametric approach multilateral productivity comparisons of firms producing multiple outputs some of which are undesirable are obtained by making two modifications to the standard farrell approach to efficiency measurement the restriction that production technology satisfy strong disposability of outputs is relaxed to allow for the fact that undesirable outputs may be freely disposable and the efficiency measures are modified to allow for an asymmetric treatment of desirable and undesirable outputs performance measures that satisfy these requirements are calculated as solutions to programming problems the methodology is applied to a sample of mills producing paper and pollutants

firm specific capital inflation persistence and the sources of business cycles this paper estimates a firm specific capital dsge model firm specific capital improves the fit of dsge models to the data as shown by a large increase in the value of the log marginal likelihood this results from a lower implied estimate of the nkpc slope for a given degree of price stickiness firm specific capital leads to a better fit to the volatilities of macro variables and a greater persistence of inflation it is also shown that firm specific capital reduces the dependence of new keynesian models on price markup shocks and that it increases the persistence of output to monetary shocks

inflation persistence and optimal monetary policy in the euro area in this paper we present an optimizing agent model for the euro area to emphasize how the existence of heterogeneity in inflation persistence across regions matters for the design of monetary policy we find supporting evidence of the existence of such a heterogeneity in inflation dynamics across euro area countries in particular based on the estimation of new keynesian phillips curves for five major countries of the euro area we find that inflation in germany has a dominant forward looking component while in the other group of countries inflation show a significant inertial backward looking behavior under this circumstance we study the welfare implications of four monetary policy rules following terms of trade shocks fully optimal optimal inflation targeting hicp targeting and output gap stabilization

intrinsic inflation persistence empirical evidence suggests that inflation determination is not purely forward looking but models of price setting have struggled to rationalize this finding without directly assuming backward looking pricing rules for firms this paper shows that intrinsic inflation persistence can be explained with no deviation from optimizing forward looking behaviour if prices that have remained fixed for longer are more likely to be changed than those set recently a relationship between the probability of price adjustment and the duration of a price spell is shown to imply a simple hybrid phillips curve including lagged and expected inflation which is estimated using macroeconomic data

measuring energy use and co2 emission performances for apec economies abstract this study proposes environmental dea based models to measure energy use efficiency co2 emissions efficiency and an environmental economic efficiency eee for the asia pacific economic cooperation apec economies for the period of 2006 2010 in our models population and total primary energy consumption are the two inputs while gdp and co2 emissions represent the desirable and undesirable outputs respectively empirical results from 20 apec economies showed that australia brunei hong kong and singapore were identified as efficient countries for five consecutive years from 2006 to 2010 in terms of energy use efficiency as for co2 emission efficiency brunei hong kong and singapore were identified as efficient countries for the five consecutive years from 2006 to 2010 as far as eee is concerned most countries in apec exhibited higher economic efficiency than environmental efficiency moreover both energy use efficiency and co2 emission efficiency were found to be significantly related to the eee value p

union wage differentials in the public and private sectors a simultaneous equations specification the paper attempts to integrate new approaches to estimating union wage effects with the analysis of public private sector wage differentials estimates of the union differential in both public and private sectors allowing for the endogeneity of union status are presented the hypothesis that the recently measured rents to public sector employment primarily reflect the recent increase in unionization in that sector is examined and receives considerable empirical support there was evidence of positive selection into the union sector especially for private sector workers union status appears to be strongly influenced by the expected wage gain from joining the union sector

nonparametric estimation of state price densities implicit in interest rate cap prices based on a multivariate extension of the constrained locally polynomial estimator of ait sahalia and duarte 2003 we provide one of the first nonparametric estimates of probability densities of libor rates under forward martingale measures and state price densities spds implicit in interest rate cap prices the forward densities and spds depend significantly on the slope and volatility of libor rates and mortgage markets activities have strong impacts on the shape of the forward densities the spds exhibit a pronounced u shape as a function of future libor rates suggesting that the state prices are high at both extremely low and high interest rates which tend to be associated with recessions and periods of high inflation respectively our results provide nonparametric evidence of unspanned stochastic volatility and suggest that the unspanned factors could be partly driven by activities in the mortgage markets the author 2009 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oxfordjournals org oxford university press

imputing a continuous income variable from grouped and missing income observations abstract most cross sectional data sets collect income in a discrete number of categories that is in grouped form to simplify the respondent s task and to encourage a response in spite of such grouped data collection many respondents refuse to provide information on income this paper develops a method to impute a continuous and reliable value for income from grouped and missing income data

the history of the phillips curve consensus and bifurcation while the early history of the phillips curve up to 1975 is well known less well understood is the post 1975 fork in the road the left fork developed a theory of policy responses to supply shocks in the context of price stickiness in the non shocked sector its econometric implementation interacts shocks with backward looking inertia the right fork approach emphasizes forward looking expectations that can jump in response to anticipated policy changes the left fork approach is better suited to explaining the postwar us inflation process while the right fork approach is essential for understanding behaviour in economies with unstable macroeconomic environments the history of the phillips curve pc has evolved in two phases before and after 1975 with a widespread consensus about the pre 1975 evolution which is well understood bifurcation begins in 1975 when the pc literature split down two forks of the road with little communication or interaction between the two forks the major contribution of this paper and hence the source of bifurcation in its subtitle is to examine contrast and test the contributions of the two post 1975 forks the pre 1975 history is straightforward and is covered in section i the initial discovery of the negative inflation unemployment relation by phillips popularized by samuelson and solow was followed by a brief period in which policy makers assumed that they could exploit the trade off to reduce unemployment at a small cost of additional inflation then the natural rate revolution of friedman phelps and lucas overturned the policy exploitable trade off in favour of long run monetary neutrality those who had implemented the econometric version of the trade off pc in the 1960s reeled in disbelief when sargent demonstrated the logical failure of their test of neutrality and finally were condemned to the wreckage of keynesian economics by lucas and sargent following the twist of the inflation unemployment correlation from negative in the 1960s to positive in the 1970s the architects of neutrality and the opponents of the keynesian trade off emerged triumphant with two major caveats that their own models based on information barriers were unconvincing and that their core result that business cycles were driven by monetary or price surprises floundered without supporting evidence after 1975 the evolution of the pc literature split in two directions each of which has largely failed to recognize the other s contributions section ii reviews the left fork of the road the revival of the pc trade off in a coherent and integrated dynamic aggregate supply and demand framework that emerged in the late 1970s in econometric tests in theoretical contributions and in intermediate macro textbooks this approach which i have called mainstream is resolutely keynesian because the inflation rate is dominated by persistence and inertia in the form of long lags on past inflation an important difference between the mainstream approach and other post 1975 developments is that the role of past inflation is not limited to the formation of expectations but also includes a pure persistence effect due to fixed duration wage and price contracts and lags between

new keynesian economics and the phillips curve models with sticky prices are an important part of new keynesian economics the author shows that several of the new keynesian models imply a formulation that is similar to the expectations augmented phillips curve of milton friedman and edmund phelps he then presents new estimates of the new keynesian phillips curve the author uses two proxies for price expectations survey based measures and an econometric based measure originally developed by bennett mccallum 1976 overall the results are consistent with the model but the survey based results are more precise suggesting that the surveys may be better measures of actual expectations copyright 1995 by ohio state university press

empirical age earnings profiles the human capital earnings function in which earnings are expressed as a quadratic in potential experience is probably the most widely accepted empirical specification in economics in spite of its widespread acceptance the human capital earnings function provides a very poor approximation of the true empirical relationship between earnings and experience the standard formulation understates early career earnings growth by about 30 50 and overstates midcareer growth by 20 50 however simple alternative specifications that fit the data are available

deflation and monetary policy in a historical perspective remembering the past or being condemned to repeat it inflation is currently low and stable in industrialized countries but might deflation replace inflation as a major policy concern we present a broad cross country historical study of deflation over the past two centuries in order to shed light on current policy challenges in the light of the relevant theoretical approaches we empirically characterize good bad and ugly deflations assess similarities between the current low inflation environment and that of the gold standard period and discuss lessons from the historical record as to policies to escape undesirable deflation and the relative merits of interest rate and monetary instruments michael bordo and andrew filardo

volunteer labor supply abstract we model the supply of volunteer labor which received an explicit wage of zero quantitatively important it constituted over 5 percent of the entire labor supply in the united states in 1980 both consumption and investment models are considered the former positing volunteering as an ordinary consumer good while the latter posits it as a means of obtaining on the job experience empirical estimation based on survey data discloses statistically significant effects of price and income variables on the supply of volunteer labor

estimating the linkage between energy efficiency and productivity abstract many analyses have referred to industrial productivity benefits associated with energy efficiency that are at least as great or larger than the energy benefits if plants with higher energy intensity also tend to have lower productivity then energy policy needs to consider this this study examines this issue for two segments of the glass industry using plant level data from the census bureau productivity is defined by the difference in best practice production efficiency as measured by data envelopment analysis dea this study uses regression analysis to estimate how differences in plant level electricity and fossil fuel intensity i e energy use per unit of production are attributable to differences in plant level productivity and other economic variables like energy prices and cumulative production in every case productivity differences between plants are statistically significant in explaining differences in plant energy intensity the coefficient that links productivity to energy efficiency yields a less than proportional impact for only one industry and fuel type for others the relationship is implies that a 1 increase in productivity increase energy efficiency by more than 1 this effect is statistically significant for flat glass but not container glass the estimates of the price and learning by doing coefficients seem reasonable but without imposing the assumption that all plants in the industry are equally productive this lends further credence to a significant relationship between productivity and energy efficiency

gender differences in observed and offered wages in canada 1980 according to the 1981 census of canada the female rate of pay is 30 percent less than the male rate the average female wage offer however is only around one half of that received by males other things being equal slightly more than one half of the difference in observed wages can be explained by diffe rences in wage related characteristics between males and females two fifths of the disparity between wage offers can be explained by the same set of factors analysis of the distribution of wage offers indicates greater wage inequality in the canadian labor market than suggested by study of observed wages

does unmeasured ability explain inter industry wage differentials this paper provides empirical assessments of the two leading explanations of measured inter industry wage differentials 1 true wage differentials exist across industries and 2 the measured differentials simply reflect unmeasured differences in workers productive abilities first we summarize the existing evidence on the unmeasured ability explanation second we construct a simple model which shows that if matching is important then endogenous job change decisions can create important self selection biases even in first differenced estimates of industry wage differentials third we analyze a sample that approximates the experiment of exogenous job loss we find that i the wage change experienced by a typical industry switcher closely resembles the difference in the relevant industry differentials estimated in a cross section and ii pre displacement industry affiliation plays an important role in post displacement wage determination

the eurozone expected inflation an option s eyes view abstract we estimate inflation risk neutral densities rnds in the euro area using inflation swaps and caps floors options and introduce a parsimonious approach to jointly estimate the rnds across horizons thus we obtain daily implicit rnds for forward measures such as the 5 year on 5 year inflation rate which although not directly traded in the market is a key reference for monetary policy then we discuss several indicators derived from the information content of those historical rnds that are relevant for policy makers and compare them in light of the ecb s decisions and communication since 2009 specifically we study the evolution of tail risks associated with deflation and high inflation the balance of inflation risks risk aversion and how forward inflation rates react to the ecb s non conventional monetary policies longer term refinancing operations ltro securities market programme smp asset purchase programme app and its variants and extensions

identification issues in limited information bayesian analysis of structural macroeconomic models the likelihood of the parameters in structural macroeconomic models typically has non identification regions over which it is constant when sufficiently diffuse priors are used the posterior piles up in such non identification regions use of informative priors can lead to the opposite so both can generate spurious inference we propose priors posteriors on the structural parameters that are implied by priors posteriors on the parameters of an embedding reduced form model an example of such a prior is the jeffreys prior we use it to conduct bayesian limited information inference on the new keynesian phillips curve with a var reduced form for us data

a non structural investigation of vix risk neutral density abstract we propose a non structural method to retrieve the risk neutral density rnd implied by options on the cboe volatility index vix the methodology is based on orthogonal polynomial expansions around a kernel density and yields the rnd of the underlying asset without the need for a parametric specification the classic family of laguerre expansions is extended to include the gig and the generalized weibull kernels we show that orthogonal polynomial expansions yield accurate approximations of the rnd of vix and they generally outperform commonly used non parametric methods when controlling for accuracy based on a panel of observed vix options we retrieve the variance swap term structure the time series of vvix the vix risk neutral moments and the volatility at risk which reveal a number of stylized facts on the rnd of vix

is the new keynesian phillips curve flat abstract this paper provides monte carlo evidence that gmm estimates of the new keynesian phillips curve are biased towards finding too much price rigidity if cost push shocks are auto correlated this result may reconcile gmm estimates with the microevidence on price rigidities

the term structure and inflation uncertainty abstract to assess the importance of inflation risk for nominal treasury yields a novel quadratic term structure model with time varying inflation risk is estimated using survey based inflation uncertainty the resulting yield decomposition captures very diverse macroeconomic dynamics of inflation and real risk premiums large and positive during the 1980s but small and negative post 2008 and generates sensible high frequency estimates of expected inflation and real short rates over a long sample the explicit link between the model implied factors and macro fundamentals reveals that short but not long run fluctuations are unspanned by yields consistent with an interest rate policy unresponsive to transient inflation shocks

social networks and private philanthropy abstract a theoretical model is provided in which an individual s social network enhances the consumption benefits from the public good we find conditions under which investments in network enhancing infrastructure would encourage individuals to donate time and money to charity an empirical investigation of the link between networks and private philanthropy is undertaken using the canadian national survey of giving volunteering and participating we find strong evidence that networks promote donations of time and money

inflation expectations and risk premiums in an arbitrage free model of nominal and real bond yields differences between yields on comparable maturity u s treasury nominal and real debt the so called breakeven inflation bei rates are widely used indicators of inflation expectations however better measures of inflation expectations could be obtained by subtracting inflation risk premiums from the bei rates we provide such decompositions using an estimated affine arbitrage free model of the term structure that captures the pricing of both nominal and real treasury securities our empirical results suggest that long term inflation expectations have been well anchored over the past few years and inflation risk premiums although volatile have been close to zero on average

the incremental information content of replacement cost earnings abstract the study explores the incremental explanatory power of replacement cost earnings variables derived from asr 190 data with respect to explaining cross sectional differences in security returns as such the study is a natural extension of previous research including analyses of the effect of security returns of asr 190 data at the time of disclosure investigations of cross sectional relationships between security returns and historical cost earnings and studies of multiple signals the basic finding is that pre holding gain net income provides no incremental explanatory powerm given knowledge of historical cost earnings however the converse does not hold taken together the findings are consistent with the contention that pre holding gain net income is a garbled version of historical cost earnings the basic finding is robust under several extensions of the initial research design the research design incorporates a two stage approach which permits a determination of the incremental explanatory power of collinear variables the findings are in contrast to those of a previous study by easman et al 1979 the nature of the difference in research design inducing the difference is identified potential reasons for the difference in findings are provided

expectation horizon and the phillips curve the solution to an empirical puzzle estimates of the slope of the phillips curve reported in the literature cover a range from roughly 0 6 to zero depending on specification forward looking specifications favored by theory produce the smallest slope estimates this paper addresses this puzzle by studying the bivariate process of inflation and unemployment in a fairly general unobserved components framework allowing for stochastic trends and related cycles analysis reveals that the slope of the implied phillips curve will depend critically on the horizon of the forward looking inflation expectation provided the cyclical component of unemployment is highly persistent empirical analysis results show that is the case suggesting that the choice of expectation horizon generally set at one quarter in the new keynesian literature may play an important role in this debate copyright 2007 john wiley sons ltd

new tests of the new keynesian phillips curve abstract lagged dependent variables typically play an important role in empirical models of inflation do these lags reflect backward looking inflation expectations or do they proxy for rational forward looking expectations as in the new keynesian phillips curve gali and gertler 1999 inflation dynamics a structural econometric analysis journal of monetary economics 44 195 222 attempt to answer this question using gmm to estimate specifications incorporating both lagged and future inflation they report small coefficients on lagged inflation and conclude that the new keynesian model provides a good first approximation to inflation dynamics we show that these tests have low power against alternative backward looking specifications and demonstrate that their results are also consistent with a backward looking phillips curve using an alternative approach we find that the new keynesian pricing model cannot explain the importance of lagged inflation in standard inflation regressions and find that forward looking terms play a very limited role in explaining inflation dynamics

the economics of options implied inflation probability density functions recently a market in options based on cpi in ation in ation caps and oors has emerged in the us this paper uses quotes on these derivatives to construct probability densities for in ation we study how these pdfs respond to news announcements and nd that the implied odds of de ation are sensitive to certain macroeconomic news releases we compare the option implied probability densities with those obtained by time series methods and use this information to construct empirical pricing kernels the options implied densities assign considerably more mass to extreme in ation outcomes either de ation or high in ation than do their time series counterparts this yields a u shaped empirical pricing kernel with investors having high marginal utility in states of the world characterized by either de ation or high in ation

decomposing real and nominal yield curves abstract inflation indexed and nominal yield curves capture investors expectations of real short rates and inflation as well as their required compensation for bearing liquidity inflation and real interest rate risk we estimate an affine term structure model that allows us to decompose real and nominal bond yields into these components and use the model to study the transmission of monetary policy the model decompositions imply that the federal reserve s announcements of lsaps lowered yields primarily by reducing real term premia changes in real term premia also account for the strong response of long term real forward rates to federal funds rate surprises

generating options implied probability densities to understand oil market events abstract we investigate the informational content of options implied probability density functions pdfs for the future price of oil using a semiparametric variant of the methodology in breeden and litzenberger 1978 we investigate the fit and smoothness of distributions derived from alternative pdf estimation methods and develop a set of robust summary statistics using pdfs estimated around episodes of high geopolitical tensions oil supply disruptions macroeconomic data releases and shifts in opec production strategy we explore the extent to which oil price movements are expected or unexpected and whether agents believe these movements to be persistent or temporary

new phillips curve under alternative production technologies for canada the united states and the euro area abstract this paper shows that alternative production technologies imply two modifications to the new phillips curve npc a specific strategic complementarity parameter that affects the relationship between real marginal cost and inflation and a specific modification to the labour share measure of real marginal cost estimates of average duration of nominal price stickiness obtained conditional on the strategic complementarity parameter are substantially smaller and therefore more plausible relative to when this parameter is ignored modifications to the marginal cost measure alone have little effect on the npc estimates the empirical fit of the npc under alternative production technologies is similar

inflation dynamics and subjective expectations in the united states i introduction this paper analyzes the ability of sticky price models to explain the dynamics of u s inflation when using survey data as proxies for inflation expectations testing sticky price models with survey expectations is attractive since to the extent that survey data correctly capture agents expectations they allow to disregard issues related to the specification of agents expectations functions one neither has to impose untested orthogonality restrictions as required when estimating under the assumption of rational expectations nor has to make restrictive assumptions about the precise form of nonrationality present in agents forecast functions this allows to focus on the question whether the economic models under consideration are correctly specified previous tests of sticky price models performed under the assumption that agents hold rational expectations have generated mixed results prominently fuhrer and moore 1995 have reported that sticky price models do not generate sufficient stickiness for inflation when the output gap is used as a measure of real marginal costs recent evidence however has shown that the empirical performance depends crucially on how one measures real marginal costs the main determinant of inflation according to sticky price models for instance gall and gertler 1999 and sbordone 2002 show that sticky price models perform well once marginal costs are approximated by average unit labor costs 1 it makes an important difference whether sticky price models successfully explain inflation dynamics as a function of output behavior or they relate inflation dynamics to the behavior of unit labor costs given that the ultimate objective is a model explaining the joint behavior of output and inflation the latter case would require an additional empirically plausible theory linking the dynamics of unit labor costs to the behavior of output this paper studies whether the currently popular new keynesian phillips curve nkpc which can be derived from calvo 1983 style sticky price models is able to explain a relationship between inflation on the one hand and output or unit labor costs on the other hand thus we let the data speak whether a theory linking output to costs is warranted once expectations are approximated by data reported in the survey of professional forecasters our main finding is that the nkpc performs equally well with both measures of marginal costs output and unit labor costs whatever measure is used the estimate of the quarterly discount factor is close to one and the point estimate of the degree of price stickiness implies that firms reset their prices roughly every five quarters on average these results suggest that potential nonrationalities in expectations as they show up in surveys have biased previous estimates using output as a measure for marginal costs quite surprisingly the same nonrationalities do not seem to play a role when using unit labor costs here our estimates confirm the results obtained by gall and gertler 1999 and sbordone 2002 who assumed rational expectations we show that the reason for this finding is that approximating the agents information set using the unit labor cost variable rests on more solid grounds than approximating it using the output variable in particular the survey data suggest that the hypothesis of rational expectations implies a too high correlation between lagged output and future inflation expectations we show that this causes the coefficient estimate for output to become negative contrary to what is implied by theory these results suggest that once one takes account of potentially nonrational expectations via survey expectations sticky price models are able to establish a close link between output dynamics and the behavior of inflation to assess the robustness of this finding we include into the price equation lags of various variables and test for their significance

what does monetary policy do to long term interest rates at the zero lower bound this article uses a structural var with daily data to identify the effects of monetary policy shocks on various longer term interest rates since the federal funds rate has been stuck at the zero lower bound the var is identified using the assumption that monetary policy shocks are heteroskedastic monetary policy shocks have especially high variance on days of fomc meetings and certain speeches while there is otherwise nothing unusual about these days a complementary high frequency event study approach is also used i find that stimulative monetary policy shocks lower treasury and corporate bond yields but the effects die off fairly fast

can volunteer work help explain the male female earnings gap using the 1987 survey of volunteer activity in canada we examine whether differential returns to volunteer work in the paid labour market can explain part of the male female earnings gap male volunteers earn on average about 11 higher incomes than their non volunteering counterparts as a result of their volunteer experience whereas comparable female volunteers and non volunteers earn similar incomes this differential return across the sexes may be partially explained by the type of volunteer activity undertaken our results indicate that as much as one third of the male female earnings gap may be attributable to the fact that the labour market rewards male and female volunteers differently
