Short-Term Forecasting of GDP Using Large Monthly Datasets: A Pseudo Real-Time Forecast Evaluation Exercise

This paper evaluates different models for the short-term forecasting of real GDP growth in ten selected European countries and the euro area as a whole. Purely quarterly models are compared with models designed to exploit early releases of monthly indicators for the nowcast and forecast of quarterly GDP growth. Amongst the latter, we consider small bridge equations and forecast equations in which the bridging between monthly and quarterly data is achieved through a regression on factors extracted from large monthly datasets. The forecasting exercise is performed in a simulated real-time context, which takes account of publication lags in the individual series. In general, we find that models that exploit monthly information outperform models that use purely quarterly data and, amongst the former, factor models perform best. JEL Classification: E37, C53.

Moses: Model of Swedish Economic Studies

MOSES is an aggregate econometric model for Sweden, estimated on quarterly data, and intended for short-term forecasting and policy simulations. After a presentation of qualitative model properties, the econometric methodology is summarized. The model properties, within sample simulations, and examples of dynamic simulation (model forecasts) for the period 2009q2-2012q4 are presented. We address practical issues relating to operational use and maintenance of a macro model of this type. The detailed econometric equations are reported in an appendix.

On Wage Formation, Wage Development and Flexibility: A Comparison between European Countries and the United States

For Germany, Spain, France, the Netherlands and the US an Error Correction Model with a long-term non-linear wage equation is estimated by 3-SLS to obtain consistent estimates, accounting for endogeneity and common shocks. On the basis of the estimated parameter elasticities of wages with respect to labour productivity, value added and consumer prices, taxes, unemployment and replacement rates are computed along with the wage contributions. The results indicate that the dominant role of prices in the formation of wages in the seventies and eighties was taken over by labour productivity in the US and unemployment in Spain and – almost- in the Netherlands at the end of the nineties. Evidence for a stronger real wage flexibility of the US in comparison with the four European countries is not found.

Information, data dimension and factor structure

This paper employs concepts from information theory for choosing the dimension of a data set. We propose a relative information measure connected to Kullback-Leibler numbers. By ordering the series of the data set according to the measure, we are able to obtain a subset of a data set that is most informative. The method can be used as a first step in the construction of a dynamic factor model or a leading index, as illustrated with a Monte Carlo study and with the US macroeconomic data set of Stock and Watson [20].

Coordination versus flexibility in wage formation: a focus on the nominal wage impact of productivity in Germany, Greece, Ireland, Portugal, Spain and the United States

Wage coordination between countries of the European Monetary Union (EMU) aims at aligning nominal wage growth with labour productivity growth at the national level. We analyse the developments in Germany, the EMU’s periphery countries Greece, Ireland, Portugal and Spain along with the United States over the period 1980 to 2010. Apart from the contribution of productivity to nominal wages, we take into account the contributions of prices, unemployment, replacement rates and taxes by means of an econometrically estimated nonlinear equation resulting from a wage bargaining model. We further study the downward rigidities of nominal wages. The findings show that in past times of low productivity, price inflation and reductions in unemployment still put significant upward pressure on nominal wage growth. The periphery countries are far from aligning nominal wage growth with productivity growth. German productivity is a major wage determinant, but surely not the only one. Within the context of a free bargaining process between employers and labour unions, policy-makers can effectively use the replacement rate to steer the nominal wages outcome.

On Wage Formation, Wage Flexibility and Wage Coordination: A Focus on the Wage Impact of Productivity in Germany, Greece, Ireland, Portugal, Spain and the United States

This paper discusses the endeavours of policy makers to come to some degree of wage coordination among EU countries, aiming at aligning wage growth with labour productivity growth at the national levels. In this context, we analyse the wage and productivity developments in Germany, the European Union’s periphery countries Greece, Ireland, Portugal, and Spain along with the US for the period 1980- 2010. Apart from the contribution of productivity to wages, we take into account the contributions of prices, unemployment, replacement rates and taxes by means of an econometrically estimated non-linear wage equation resulting from a wage bargaining model. We further study the downward rigidities of wages in depth. The findings show that in past times of low productivity, price inflation and reductions in unemployment put significant upward pressure on wage growth, also in the low inflationary period of the 2000s. Greece, Ireland, Portugal and Spain are far from aligning wage growth with productivity growth. German productivity is a major German wage determinant, but surely not the only one. To steer wages, policy makers can effectively use the replacement rate.

Regional and sectoral dynamics of the Dutch staffing labor cycle

This study analyses the dynamic characteristics of staffing employment across different business sectors and across different geographical regions in the Netherlands. We analyse a micro data set of the market leader of the Dutch staffing employment market, i.e. Randstad. We apply the dynamic factor model to extract common information out of a large data set and to isolate business cycle frequencies with the aim of forecasting economic activity. We identify regions and sectors whose cyclical developments lead the staffing labour cycle at the country level. The second question is then which model specification can exploit best the identified leading indicators at the disaggregate level to forecast the country aggregate? The dynamic factor model turns out to outperform univariate benchmark forecasting models by exploiting the substantial temporal variation of the staffing labour market at the disaggregate level.

On Wage Formation, Wage Development and Unemployment - The Case of Ireland, Spain and the Netherlands

In the mid ninetees unemployment substantially decreased in some EMU-countries, notably in Ireland, Spain and the Netherlands. One important factor underlying this development is wage moderation. This paper investigates wage formation and wage development. Using a theoretical wage bargaining model main determinants of formation are described, a non-linear wage equation is derived and estimated with annual or quarterly data of the Netherlands, Spain and Ireland. The effects of the individual determinants on wages are calculated and, in addition, each determinant’s contribution to the total wage developments is analysed over the last three decades. It follows that each decade is characterised by few dominating determinants. The contribution of unemployment has altered considerably.
