wage norms capital accumulation and unemployment a post keynesian view the paper presents a post keynesian view of unemployment it argues first that the effective labour demand need not be downward sloping with respect to real wages and aggregate demand need not be downward sloping with respect to inflation second that there is a broad case for unemployment hysteresis understood as endogeneity of the non accelerating inflation rate of unemployment nairu based on social norms in wage bargaining and on the supply side effects of capital accumulation and third that much as keynes argued capital investment rather than labour market institutions is the key variable to explain changes in aggregate unemployment performance across countries and over time overall the paper advocates a keynesian view of the nairu where effective demand determines unemployment in the short run and the deviation of actual unemployment from the nairu determines the change in inflation in the medium term the nairu is endogenous and follows actual unemployment copyright 2011 oxford university press

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

are some forecasters really better than others in any dataset with individual forecasts of economic variables some forecasters will perform better than others however it is possible that these ex post differences reflect sampling variation and thus overstate the ex ante differences between forecasters in this paper we present a simple test of the null hypothesis that all forecasters in the us survey of professional forecasters have equal ability we construct a test statistic that reflects both the relative and absolute performance of the forecaster and use bootstrap techniques to compare the empirical results with the equivalents obtained under the null hypothesis of equal forecaster ability results suggest little support for the idea that the best forecasters are actually innately better than others though there is evidence that a relatively small group of forecasters perform very poorly

modelling inflation volatility this paper discusses estimation of us inflation volatility using time varying parameter models in particular whether it should be modelled as a stationary or random walk stochastic process specifying inflation volatility as an unbounded process as implied by the random walk conflicts with priors beliefs yet a stationary process cannot capture the low frequency behaviour commonly observed in estimates of volatility we therefore propose an alternative model with a change point process in the volatility that allows for switches between stationary models to capture changes in the level and dynamics over the past 40 years to accommodate the stationarity restriction we develop a new representation that is equivalent to our model but is computationally more efficient all models produce effectively identical estimates of volatility but the change point model provides more information on the level and persistence of volatility and the probabilities of changes for example we find a few well defined switches in the volatility process and interestingly these switches line up well with economic slowdowns or changes of the federal reserve chair moreover a decomposition of inflation shocks into permanent and transitory components shows that a spike in volatility in the late 2000s was entirely on the transitory side and characterized by a rise above its long run mean level during a period of higher persistence

estimation and forecasting in models with multiple breaks this paper develops a new approach to change point modelling that allows the number of change points in the observed sample to be unknown the model we develop assumes that regime durations have a poisson distribution it approximately nests the two most common approaches the time varying parameter tvp model with a change point every period and the change point model with a small number of regimes we focus considerable attention on the construction of reasonable hierarchical priors both for regime durations and for the parameters that characterize each regime a markov chain monte carlo posterior sampler is constructed to estimate a version of our model which allows for change in conditional means and variances we show how real time forecasting can be done in an efficient manner using sequential importance sampling our techniques are found to work well in an empirical exercise involving u s gdp growth and inflation empirical results suggest that the number of change points is larger than previously estimated in these series and the implied model is similar to a tvp with stochastic volatility model

hysteresis in unemployment after two decades of ratcheting unemployment in europe most economists agree that structural changes associated with higher equilibrium rates of unemployment have occurred but the direction of causality is a matter of controversy have the structural changes caused the long lasting increases in actual unemployment or have the increases in actual unemployment caused the structural changes the latter possibility is often referred to as hysteresis during the past decade a distinct research program has evolved around the idea that equilibrium employment tracks actual unemployment this survey reviews the various hysteretic explanations offered in the literature and evaluates their empirical standing

a new model of trend inflation this article introduces a new model of trend inflation in contrast to many earlier approaches which allow for trend inflation to evolve according to a random walk ours is a bounded model which ensures that trend inflation is constrained to lie in an interval the bounds of this interval can either be fixed or estimated from the data our model also allows for a time varying degree of persistence in the transitory component of inflation in an empirical exercise with cpi inflation we find the model to work well yielding more sensible measures of trend inflation and forecasting better than popular alternatives such as the unobserved components stochastic volatility model this article has supplementary materials online

portfolio choice in the presence of background risk in this paper we focus on how the presence of background risks from sources such as labour and entrepreneurial income influences portfolio allocations this interaction is explored in a theoretical model that is calibrated using cross sectional data from a variety of sources the model is shown to be consistent with some but not all aspects of cross sectional observations of portfolio holdings the paper also provides a survey of the extensive theoretical and empirical literature on portfolio choice

unemployment wage bargaining and capital labour substitution many economists believe that capital accumulation technical progress and labour force expansion have no lasting effect on unemployment this view rests on the empirically doubtful assumption that the elasticity of substitution between labour and capital is equal to unity i e production is cobb douglas using a simple model based on the work of layard nickell and jackman this paper demonstrates that with a lower elasticity of substitution the equilibrium unemployment rate is affected by all of the above factors it considers briefly how capital accumulation may be endogenised and what long run implications this has for unemployment copyright 1999 by oxford university press

the consequences of fiscal stimulus on public debt a historical perspective the current policy agenda of neoclassical macroeconomics as expressed within conservative political circles in the uk and european union is that fiscal contraction is the lever that can bring about recovery from the current economic downturn allegedly the reason is that when business sees that the government balance sheet is improving and public debt declining there will be greater confidence in the country s economic prospects and this increased confidence will lead to higher investment this in turn will lead to growth and the road to economic recovery this study examines the impact of government stance on public debt for 11 oecd countries for which data on the relevant factors are available from 1881 to 2011 contrary to traditional predictions it turns out that over this long historical span fiscal contractions deteriorated rather than improved public debt as a percentage of gdp this implies that fiscal austerity exacerbates the lack of demand and deteriorates rather than enhances the prospects of economic recovery

capital accumulation and unemployment new insights on the nordic experience this paper takes a fresh look at the analysis of labour market dynamics and argues that capital accumulation plays a fundamental role in shaping unemployment movements this role has generally been examined by considering indirect transmission channels of the capital stock effects i e using variables like interest rates or investment ratios in the estimation of single equation unemployment rate models here we advocate a different approach we directly estimate the effects of capital stock in the labour market by applying the chain reaction theory of unemployment and we find that capital stock is a major determinant of unemployment in the nordic countries in particular the different unemployment experiences of these economies derive from the temporary albeit prolonged negative shocks to capital stock growth in denmark and sweden and the permanent downturn of capital stock growth in finland we are thus able to explain why the crisis of the early 1990s had a more acute impact in finland than in its twin economy sweden

measuring inflation expectations uncertainty using high frequency data inflation expectations play a key role in determining future economic outcomes the associated uncertainty provides a direct gauge of how well anchored the inflation expectations are we construct a model based measure of inflation expectations uncertainty by augmenting a standard unobserved components model of inflation with information from noisy and possibly biased measures of inflation expectations obtained from financial markets this new model based measure of inflation expectations uncertainty is more accurately estimated and can provide valuable information for policymakers using u s data we find significant changes in inflation expectations uncertainty during the great recession

money market mutual fund maturity and interest rates the average maturity of money market mutual funds ranged from twenty nine to fifty three days during 1982 through 1990 according to the popular press changes in this time series provide interest rate forecasts the hypothesis is that fund managers lengthen their maturities when interest rates will be falling while the maturities are shortened when rate increases are imminent granger causality tests reject this hypothesis however there is a causal relation in the opposite direction interest rates granger cause average fund maturity indicating that on average fund managers respond to past rate changes copyright 1992 by ohio state university press

the inefficiency of the mean analyst forecast as a summary forecast of earnings we show analytically that mean analyst forecasts inefficiently aggregate information by assigning too much weight to analysts common information relative to their private information when used as a summary forecast measure of forthcoming earnings a more precise summary forecast of earnings than the current mean forecast is the current mean forecast plus a positive multiple of the change in the mean forecast

global factors and trend inflation abstract we develop an empirical model to study the influence of global factors in driving trend inflation and the inflation gap we apply our model to 7 developed economies and 21 emerging market economies our results suggest that while global factors can have a sizeable influence on the inflation gap they play only a marginal role in driving trend inflation much of the influence of global factors in the inflation gap may be reflecting commodity price shocks finally we find the effect of global factors to be greater in our sample of emerging market economies relative to the developed economies there is some evidence which suggest propagation mechanisms which may reflect institutional structures or policy choices can explain the greater role for global factors in driving trend inflation in emerging market economies

the role of shocks and institutions in the rise of european unemployment the aggregate evidence two key facts about european unemployment must be explained the rise in unemployment since the 1960s and the heterogeneity of individual country experiences while adverse shocks can potentially explain much of the rise in unemployment there is insufficient heterogeneity in these shocks to explain cross country differences alternatively while explanations focusing on labour market institutions explain current heterogeneity well many of these institutions pre date the rise in unemployment based on a panel of institutions and shocks for 20 oecd nations since 1960 we find that the interaction between shocks and institutions is crucial to explaining both stylised facts

aggregate demand conflict and capacity in the inflationary process this paper focuses on an alternative perspective on inflation to that of the non accelerating inflation rate of unemployment nairu it indicates that there are no automatic forces leading to a level of aggregate demand consistent with constant inflation inflationary pressures arise from conflict over income shares and from cost elements with the price of raw materials especially oil being the most important there are supply side factors impinging on the inflationary process which arise from the level of productive capacity relative to aggregate demand the supply side constraints are viewed as arising from capacity constraints rather than from the operation of the labour market copyright 2005 oxford university press

changing beliefs and systematic rational forecast errors with evidence from foreign exchange this paper addresses a new interpretation to the appearance in the early 1980s of systematic errors in forecasting the dollar exchange rate following a change in the process of a fundamental variable market participants revise their beliefs about the process using bayes rule since the market does not immediately recognize the change forecast errors are on average wrong during a period when the market is rationally learning for conservative parameter values the learning behavior of the dollar exchange rate in the early 1980s appears consistent with about half of the dollar s underprediction implied by the forward market copyright 1989 by american economic association

changes in the federal reserve s inflation target causes and consequences this paper estimates a new keynesian model to draw inferences about the behavior of the federal reserve s unobserved inflation target the results indicate that the target rose from 1 1 4 percent in 1959 to over 8 percent in the mid to late 1970s before falling back below 2 1 2 percent in 2004 the results also provide some support for the hypothesis that over the entire postwar period federal reserve policy has systematically translated short run price pressures set off by supply side shocks into more persistent movements in inflation itself although considerable uncertainty remains about the true source of shifts in the inflation target jel e31 e32 e52

general equilibrium macroeconomic models of unemployment can they explain the unemployment path in the oecd several theories which seek to explain the high and apparently persistent unemployment in the oecd countries over the past two decades have arisen within the framework of imperfections in the goods and labour markets probably the most prominent theories within this class of models are the general equilibrium models of phelps 1994 layard and nickell 1986 and layard et al 1991 labelled structuralist theories of unemployment by phelps 1994 common to the structuralist theories is that the low frequency movements in unemployment or the nairu are determined by structural variables such as unemployment benefits taxes real interest rates etc however the high frequency movements in unemployment are determined by wage and price surprises and in the layard and nickell 1986 model also by cyclical mark ups employment is entirely determined by the firms willingness to supply and the firms are never sales constrained by contrast the general equilibrium model of sarantis 1993 which is in post keynesian spirit suggests that unemployment on all frequencies is mainly an outcome of demand side factors in this model imperfections in the goods and labour markets are less important determinants of unemployment in this paper i estimate the extent to which the models of phelps 1994 layard and nickell 1986 henceforth l n and sarantis 1993 are able to explain the unemployment path of the oecd countries using annual data over the period 1960 to 1993 the theoretical set up of the models is presented in section 1 and the empirical estimates are set out in section 2

the standard error of regressions statistical significance as used in economics has weak theoretical justification in particular it merges statistical and substantive significance the 182 papers using regression analysis in the american economic review in the 1980s were tested against 19 criteria for the accepted use of statistical significance most some three quarters of the papers did poorly likewise textbooks in econometrics do not distinguish statistical and economic significance statistical significance should not be the focus of empirical economics

the rationality of federal funds rate expectations evidence from a survey this study finds that expectations of two week maintenance period average federal funds rates as measured by the money market services survey from march 1984 to november 1987 are biased only marginally outperform random walk forecasts and have forecast errors that are correlated with in sample information however these results are tempered by findings that the survey forecasts incorporate the information in out of sample arima forecasts although the latter are less accurate than random walk forecasts in addition the accuracy of the survey forecasts increases for maintenance periods in which the discount rate changes copyright 1989 by ohio state university press

how well do economists forecast stock market prices a study of the livingston surveys the desire to forecast stock prices appears to be eternal alfred cowles 1933 was one of the first researchers to evaluate statistically how well professional forecasters predict stock prices in this tradition our paper will explore the statistical properties of the livingston stock market forecasts a number of recent studies including those by josef lakonishok 1980 bryan brown and shlomo maital 1981 and douglas pearce 1984 finds that the livingston stock market forecasts are statistically biased and or do not utilize all available information i e are informationally inefficient in contrast to earlier studies we find using 61 semiannual livingston surveys from june 1955 through june 1985 that stock market forecasts are statistically unbiased and minimum error variance estimators in section i we show that earlier studies are likely to mask the true relationships between stock market forecasts and realized rates of return because of inappropriate computational algorithms in section ii we present our statistical results based upon the corrected data algorithm we provide a brief summary of the paper in the last section 1 computing livingston stock market rate of return forecasts

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

what do we know about investment under uncertainty recent theoretical developments relating to investment under uncertainty have highlighted the importance of irreversibility for the timing of investment expenditures and their expected returns this has subsequently stimulated a growing empirical literature which examines uncertainty and threshold effects on investment behaviour this paper presents a review of this literature a variety of methods have been used to investigate the empirical implication of irreversibility in investment the majority focusing on the relationship between investment flows and proxy measures of uncertainty a general conclusion is that increased uncertainty at both aggregate and disaggregate levels leads to lower investment rates this suggests that there is an irreversibility effect under which greater uncertainty raises the value of the call option to delay a commitment to investment this effect appears to dominate any positive impact on investment arising from the fact that greater uncertability under certain circumstances increases the marginal profitability of capital the methods used raise a number of issues which call into question the reliability of the findings and these are addressed in the paper however if such irreversibility effects are present then their omission from traditional investment models casts doubt on the efficacy of such specifications jel classification d81 d92 e22

a new model of inflation trend inflation and long run inflation expectations a knowledge of the level of trend inflation is key to many current policy decisions and several methods of estimating trend inflation exist this paper adds to the growing literature which uses survey based long run forecasts of inflation to estimate trend inflation we develop a bivariate model of inflation and long run forecasts of inflation which allows for the estimation of the link between trend inflation and the long run forecast thus our model allows for the possibilities that long run forecasts taken from surveys can be equated with trend inflation that the two are completely unrelated or anything in between by including stochastic volatility and time variation in coefficients it extends existing methods in empirically important ways we use our model with a variety of inflation measures and survey based forecasts for several countries we find that long run forecasts can provide substantial help in refining estimates and fitting and forecasting inflation the same evidence indicates it is less helpful to simply equate trend inflation with the long run forecasts

time variation in term premia international survey based evidence using a large previously unexplored data set of survey based interest rate forecasts that covers a broad range of countries this paper re examines the expectations hypothesis of the term structure of interest rates we find that survey based interest rate forecasts outperform not only a random walk forecast but also outperform forecasts from forward rates when using these superior survey based forecasts in a modified expectations hypothesis test the expectations hypothesis is rejected for fewer countries at lower significance levels and has greater explanatory power than when using a traditional forward rates based test we furthermore document strong time variation in the term premia which is an important reason why the traditional expectations hypothesis test is rejected so frequently this time variation seems to arise from the changing attitudes towards risk among market participants and as a compensation for the change in liquidity in the term structure finally we find that generalizing findings from earlier u s studies to other countries may lead to bias in the true economic relationships in these countries

trend inflation indexation and inflation persistence in the new keynesian phillips curve purely forward looking versions of the new keynesian phillips curve nkpc generate too little inflation persistence some authors add ad hoc backward looking terms to address this shortcoming we hypothesize that inflation per sistence results mainly from variation in the long run trend component of inflation which we attribute to shifts in monetary policy we derive a version of the nkpc that incorporates a time varying inflation trend and examine whether it explains the dynamics of inflation when drift in trend inflation is taken into account a purely forward looking version of the model fits the data well and there is no need for backward looking components jel e12 e31 e52 in this paper we consider the extent to which guillermo calvo s 1983 model of nominal price rigidities can explain inflation dynamics without relying on arbitrary backward looking terms in its baseline formulation the calvo model leads to a purely forward looking new keynesian

price level uncertainty and instability in the united kingdom abstract was uk inflation more stable and or less uncertain before 1914 or after 1945 we address these questions by estimating a statistical model with changing volatilities in transient and persistent components of inflation three conclusions emerge first since periods of high and low volatility occur in both eras neither features uniformly greater stability or lower uncertainty when comparing peaks with peaks and troughs with troughs however we find clear evidence that the price level was more stable before world war i we also find some evidence for lower uncertainty at pre 1914 troughs but its statistical significance is borderline

multiperiod forecasts of interest rates the accuracy of forecasts of interest rates over different forecast horizons and time periods is examined the results indicate a deterioration in absolute forecast accuracy measured by the mean absolute error and the root mean squared error but no decrease in relative accuracy measured by the theil coefficient with an increase in the forecast span the results also indicate a decline in accuracy in periods of volatile interest rates support is found for the hypothesis that the ratio of the variability of predicted changes to that of actual changes falls with an increase in the forecast horizon

a new time varying parameter autoregressive model for u s inflation expectations we study the evolution of u s inflation by means of a new noncausal autoregressive model with time varying parameters that outperforms the corresponding causal and constant parameter noncausal models in terms of fit and forecast accuracy our model also beats the unobserved component stochastic volatility ucsv model one of the best performing univariate inflation forecasting models in terms of both point and density forecasts we also show how the new keynesian phillips curve can be estimated based on our noncausal model both expected and lagged inflation turn out important but the former dominates in determining the current inflation

capital accumulation labour market institutions and unemployment in the medium run according to the mainstream view labour market institutions lmis are the key determinants of unemployment in the medium run the actual empirical explanatory power of measures for labour market institutions however has recently been called into question the keynesian view holds periods of high real interest rates and insufficient capital accumulation responsible for unemployment empirical work in this tradition has paid little attention to the role of lmis this paper contributes to the debate by highlighting the role of autonomous changes in capital accumulation as a macroeconomic shock in the empirical analysis medium term unemployment is explained by capital accumulation lmis and a number of macroeconomic shocks in a panel analysis covering 20 oecd countries the economic effects of changes in lmi variations in capital accumulation and other macro shocks are compared capital accumulation and the real interest rate are found to have statistically significant effects that are robust to the inclusion of control variables and show larger effects than lmi

the stochastic volatility in mean model with time varying parameters an application to inflation modeling this article generalizes the popular stochastic volatility in mean model to allow for time varying parameters in the conditional mean the estimation of this extension is nontrival since the volatility appears in both the conditional mean and the conditional variance and its coefficient in the former is time varying we develop an efficient markov chain monte carlo algorithm based on band and sparse matrix algorithms instead of the kalman filter to estimate this more general variant the methodology is illustrated with an application that involves u s u k and germany inflation the estimation results show substantial time variation in the coefficient associated with the volatility highlighting the empirical relevance of the proposed extension moreover in a pseudo out of sample forecasting exercise the proposed variant also forecasts better than various standard benchmarks
