US, Japan and the euro area: comparing business-cycle features

There has been much discussion of the differences in macroeconomic performance and prospects between the US, Japan and the euro area. Using Markov-switching techniques, in this paper we identify and compare specifically their major business-cycle features and examine the case for a common business cycle, asymmetries in the national cycles and, using a number of algorithms, date business-cycle turning points. Despite a high degree of trade and financial linkages, the cyclical features of US, Japan and the euro area appear quite distinct. Documenting and comparing such international business-cycle features can aid forecasting, model selection and policy analysis etc. JEL Classification: C32, F20business-cycle, euro area, Japan, US

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 “fundamental inflation”. We start from a careful modeling of optimal price setting allowing for non-unitary factor substitution, non-neutral technical change and timevarying factor utilization rates. This ensures the resulting real marginal cost measures match volatility reductions and level changes witnessed in many US time series. The cost measure comprises conventional counter-cyclical cost elements plus pro-cyclical (and co-varying) utilization rates. Although pro-cyclical elements dominate, real marginal costs 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.

Is forecasting with large models informative? Assessing the role of judgement in macroeconomic forecasts

We evaluate residual projection strategies in the context of a large-scale macro model of the euro area and smaller benchmark time-series models. The exercises attempt to measure the accuracy of model-based forecasts simulated both out-of-sample and in-sample. Both exercises incorporate alternative residual-projection methods, to assess the importance of unaccounted-for breaks in forecast accuracy and off-model judgment. Conclusions reached are that simple mechanical residual adjustments have a significant impact of forecasting accuracy irrespective of the model in use, ostensibly due to the presence of breaks in trends in the data. The testing procedure and conclusions are applicable to a wide class of models and thus of general interest.

Forecasting inflation with thick models and neural networks

This paper applies linear and neural network-based “thick” models for forecasting inflation based on Phillips–curve formulations in the USA, Japan and the euro area. Thick models represent “trimmed mean” forecasts from several neural network models. They outperform the best performing linear models for “real-time” and “bootstrap” forecasts for service indices for the euro area, and do well, sometimes better, for the more general consumer and producer price indices across a variety of countries.

New Keynesian Phillips Curves: a reassessment using euro-area data

Using euro-area data, we re-examine the empirical success of New Keynesian Phillips Curves (NKPCs). The nature of our re-evaluation relies on the actual empirical underpinnings of such estimates: we find existing estimates un-robust and – given that key parameters are generally calibrated rather than estimated – potentially at odds with the data. We re-estimate with a wellspecified optimizing supply-side (which attempts to treat non-stationarity in factor income shares and mark-ups) and this allows us to derive estimates of technology parameters and marginal costs. Our resulting estimates of the euro-area NKPCs are robust, provide reasonable estimates for fixed-price durations and discount rates and embody plausible dynamic properties. Our method for identifying and estimating New Keynesian Phillips curves has general applicability to a wide set of countries and might also be used in identifying sectoral NKPCs.

The monetary transmission mechanism at the euro-area level: issues and results using structural macroeconomic models

This paper addresses some of the issues faced by macroeconomic model builders in analysing the monetary transmission mechanism. These include the sensitivity of the policy simulation results to changes in the monetary and fiscal policy rule and the introduction of forward-looking behaviour in the model. To illustrate the importance of these issues the paper reports the results of variant monetary policy simulations at the euro-area level using the AWM and NiGEM models JEL Classification: C50, C52, E5euro area, macro models, monetary transmission mechanism

Financial market frictions in a model of the euro area

We build a model of the euro area incorporating financial market frictions at the level of firms and households. Entrepreneurs borrow from financial intermediaries in order to purchase business capital, in the spirit of the "financial accelerator" literature. We also introduce two types of households that differ in their degree of time preference. All households have preferences for housing services. The impatient households are faced with a collateral constraint that is a function of the value of their housing stock. Our aim is to provide a unified framework for policy analysis that emphasizes financial market frictions alongside the more traditional model channels. The model is estimated by Bayesian methods using euro area aggregate data and model properties are illustrated with simulation and conditional variance and historical shock decomposition.

Medium run redux: technical change, factor shares and frictions in the euro area

We develop a framework for analyzing “medium-run” departures from balanced growth, and apply it to the economies of continental Europe. A time-varying factor-augmenting production function (mimicking “directed” technical change) with a below-unitary substitution elasticity coupled with supporting short-run factor demands (and price setting) is shown to account for the observed dynamics of factor incomes shares, capital deepening and the capital-output ratio. Based on careful data accounting, we also identify a rising mark-up, which we ascribe to the rise of Services. The balanced growth path emerges as a special (and testable) case of our framework, as do existing strands of medium-run debates.

Unemployment, Hysterisis and Transition

We quantify the degree of persistence in the unemployment rates of transition countries using a variety of methods benchmarked against the EU. In doing so, we will also characterize the dynamic behavior of unemployment in the CEECs during the past decade. In part of the paper, we will work with the concept of linear ÒHysteresisÓ as described by the presence of unit roots in unemployment as in most empirical research on this area. Given that this is potentially a rather narrow definition, we will also take into account the existence of structural breaks and non-linear dynamics in unemployment in order to allow for a richer set of dynamics. Finally, we examine whether CEECsÕ unemployment presents features of multiple equilibria, that is, if it remains locked into a new level whenever a structural change occurs. Our findings show that, in general, we can reject the unit root hypothesis after controlling for structural changes and business cycle effects, but we can observe the presence of a high and low unemployment equilibria. The speed of adjustment is faster for CEECs than the EU, although CEECs tend to move more frequently between equilibria.unemployment, hysterisis, unit root, transition

Happiness Inertia: Analytical Aspects of the Easterlin Paradox

Using a New-Keynesian flexi-price model with external habit formation in consumption and labor supply, we identify the channels underlying the Easterlin Paradox (or “Happiness Inertia”, its generalization). These include whether external habit formation is in “difference” or “ratio” form; the growth and convexity characteristics of non-pecuniary effects; and the nature of risk aversion. We show that the impact of labor habit formation on welfare can (unlike consumption) be positive or negative. The form of habit formation (rather than habit per se) is a key determinant of whether welfare functions reproduce happiness inertia; only when habit is modelled in ratio form, does this possibility open up. The model thus bridges the gap between theoretical models and social policy, pecuniary and non-pecuniary motives.Efficiency wage; Unemployment; Regional growth.
