Cointegration and common trends on the West German labour market

In this paper we analyze the West German labour market by means of a cointegrated structural VAR model. We find sensible stable long-run relationships that are interpreted as a labour demand, a wage setting and a goods market equilibrium. In order to study the dynamic behaviour of the model we identify two common trends that push unemployment. We find that goods market shocks have only transitory impacts on unemployment. In the long run, it is almost equally determined by technology and labour supply factors. However, transitory shocks have major importance in the shorter run since adjustment processes are rather sluggish. First version received: Sept. 1998/Final version accepted: Feb. 2000     

Detrending methods and stylized facts of business cycles in Norway – an international comparison

This paper analyses the stylized facts of business cycles in Norway, by comparing different detrending methods. As the choice of the appropriate data transformation depends on the nature of the underlying dynamic properties of the time series, a set of unit root tests are first applied to the data. The detrended data are analysed, both in the time domain and the frequency domain. The evidence suggests that whereas some variables (e.g. consumption and investment) behave consistently procyclically with GDP, for other variables (e.g. real wage and prices), the business cycle properties vary considerably with the detrending methods used. The results are evaluated from a real business cycle perspective, but overall, there is little evidence to support a (supply driven) real business cycle. Symmetries in business cycles are finally analysed by comparing the business cycles in Norway and selected countries. First version received: April 1997 / Final version received: November 1999     

Working time, employment, and work sharing: Evidence from Sweden

We study three questions which are important for work sharing to increase employment. First, is there a negative long-run relation between working time and employment? Second, are hours per worker exogenous with respect to wages and employment? Third, can policy makers influence actual hours per worker? We formulate a theoretical model for employment, hours per worker, production, and real wages. A VAR model with cointegrating constraints is estimated by maximum likelihood using Swedish private sector data 1970:1–1990:4. We find (i) no long-run relation between hours per worker and employment, (ii) that hours per worker are endogenous with respect to the estimation of long-run parameters, and (iii) that legislated working time and hours per worker are related to each other in the long run.

Unobserved components in an error-correction model of consumption for Southern European countries

In this paper we show how the potential misspecification of the consumption function can be ameliorated by approximating any unmodelled long run variation with an unobserved component in the form of a time-varying trend. This methodology is applied to Greek, Portuguese and Spanish consumption functions during the post-second World war period. The empirical evidence suggests that there are many determinants of long-run consumption in these countries, in addition to income and inflation, and these unobserved long-run effects are captured by a nonstationary stochastic component. The long-run elasticity of consumption with regards to the unobserved component is greater than unity in all countries. First version received: January 1999/Final version received: June 2000     

Dynamic spatial modelling of regional convergence processes

Econometric analysis of convergence processes across countries or regions usually refers to a transition period between an arbitrary chosen starting year and a fictitious steady state. Panel unit root tests and panel cointegration techniques have proved to belong to powerful econometric tools if the conditions are met. When referring to economically defined regions, though, it is rather an exception than the rule that coherent time series are available. For this case we introduce a dynamic spatial modelling approach which is suitable to trace regional adjustment processes in space instead of time. It is shown how the spatial error-correction mechanism (SEC model) can be estimated depending on the spatial stationarity properties of the variables under investigation. The dynamic spatial modelling approach presented in this paper is applied to the issue of conditional income and productivity convergence across labour market regions in unified Germany.First version received: December 2002/Final version received: June 2003We would like to thank an anonymous referee for his helpful comments.     

An intertemporal system of dynamic consumer demand functions

This paper constructs and estimates a system of dynamic consumer demand equations under the assumption of rational expectations about anticipated human wealth. The traditional one-period budget constraint is replaced by the lifetime anticipated wealth constraint. Lagged dependent variables are rationalized by an adjustment cost argument. In the model presented, both the dynamic adjustment coefficients as well as the parameters characterizing the underlying long-run preferences are identified and can be estimated. We find that a weak version of the REH cannot be rejected on the data. In common with most empirical studies on demand behaviour we have to reject the symmetry restrictions.     

Causality tests of budget and current account deficits: Cross-country comparisons

This study attempts to determine the causal relationship between budget and current account deficits as well as the direction of such causality. A selected sample of some developed and developing countries with annual time series data is used and cointegration techniques are applied to bring evidence regarding this important issue. Our results do not support any long-run relationship between the two deficits for developed countries while the data for developing countries do not reject such a relationship. However, our results suggest a causal relationship between the two deficits for most of the sample countries. First version received: November 1996/final version received: September 1998     

Common serial correlation and common business cycles: A cautious note

This paper examines the frequency-domain implications of the serial correlation common feature in order to evaluate its merits as an indicator of common business cycles among economic variables. It is shown that the presence of the serial correlation common feature in the first differences of a set of I(1) time series is not informative for the degree and the lead-lag structure of their comovements at the business cycle frequencies.

Smooth transition trends and labor force participation rates in the United States

This paper employs smooth transition trend models to investigate the long-run time series behavior of quarterly US labor force participation rates. In particular, we examine whether long-run growth in labor force participation rates can be modeled by smooth transitions between states rather than as abrupt mean level changes or as a stochastic trend. Smooth transitions permit for non-instantaneous adjustment of individual workers to changes associated with economic events or general labor market conditions. We employ unit root testing procedures with alternatives characterized by stationary fluctuations around one or two smooth transitions in linear trend. We examine labor force participation rates by gender- and age-specific groups. The results indicate that all female and most male participation series are better characterized as stationary processes that undergo transitional deterministics.     

Estimation of a German money demand system – a long-run analysis

This study presents a multivariate analysis of the stability of long-run relationships between variables that influence the conduct and transmission process of the German monetary policy. The initial VAR comprises the variables real money M3, real GNP, the inflation rate, a long-term and a weighted short-term interest rate. A multivariate approach has been chosen, as this allows for more than one cointegration relationship and to test restrictions on the cointegration space. In contrast to most other studies on German monetary policy, three stable and economically plausible cointegration relationships are obtained simultaneously within the framework of the Johansen procedure: a money demand relationship, a long-run Fisher effect and a long-run relationship between the short- and the long-term interest rate. It is apparent that the structural break of German reunification can be modelled incorporating dummy variables in the model.

Moments of cross-sectional stock market returns and the German business cycle

Based on monthly data covering the period from 1987 to 2021, we analyse whether cross-sectional moments of stock market returns may provide information about the future position of the German business cycle. We apply in-sample forecasting regressions with and without leading indicators as control variables, pseudo-out-of-sample exercises, autoregressive distributed lag models, and impulse-response functions estimated by local projections. We find in-sample predictive power of the first and third cross-section moments for the future growth of industrial production, even if one controls for well-established leading indicators for the German business cycle. Out-of-sample tests show that these variables reduce the relative mean squared error compared with benchmark models. We do not find a long-run relation between the moment series and industrial production. The dynamic response of industrial production to a shock on the cross-section moments is in line with the other results.     

The link between inflation and inflation uncertainty: Evidence from G7 countries

In this paper we adopt the Markov-switching heteroscedasticity model to analyse the inflation series for G7 countries and examine the interaction between inflation rate and its uncertainty over both the short- and long-run. It is found that the relationship between inflation and inflation uncertainty depends on whether the shock is permanent or transitory. The relationship also differs from country to country. High uncertainty about long-run inflation is associated with a significant positive shift in inflation for Canada, Germany, and Japan. High uncertainty about short-run inflation is associated with a significant positive shift in inflation for Germany and USA, and a significant negative shift in inflation for Canada. The modelling approach employed in this paper is empirically supported by various diagnostics including the Vuong test. We also derive the two components of the variance of inflation forecast for a particular forecast horizon. It is found that the inflation uncertainty increases at all horizons in the middle of 1970s and return to the low level in the middle of 1980s.First version received: June 2001/Final version received: October 2003We would like to thank three anonymous referees for many helpful comments and suggestions.     

Long-run matching relationship in the Japanese labor market

This paper investigates the long-run relationship among new hiring, unemployment (job seekers), and unfilled vacancies in Japan, using an annual panel data on 47 prefectures for 1972-1999. We find that these three variables are I(1) processes, and are cointegrated in our panel data. Further, we estimate the panel cointegration equation derived from a Cobb-Douglas matching function by the heterogeneous fully modified OLS and heterogeneous dynamic OLS. The estimation results reveal that conventional within estimates could have non-negligible biases.First version received: November 2002/Final version received: October 2003All correspondence to Shigeki Kano.

A monetary analysis of the Drachma/ECU exchange rate determination, 1980–1991

The validity of the monetary approach to the Drachma/ECU exchange rate determination is investigated through cointegration, impulse response and variance decomposition analysis. The empirical results reported confirm recent findings that the monetary approach may be interpreted as a long-run equilibrium condition with highly complex short-run dynamics.

Dynamic factor demands and adjustment costs: An analysis of bell Canada's Technology

In this paper a dynamic model of production is estimated for Bell Canada. The dynamics arise from the costs of adjustment associated with capital expansion. Estimation results showed that there are significant adjustment costs. Thus, the hypothesis of long-run cost minimization is rejected. As Bell Canada increases its capital stock by $1, there are additional adjustment costs of $0.36. This result implies that Bell Canada minimizes the present value of production and adjustment costs which results in a short-run equilibrium position. Price, substitution and output elasticities are estimated. In the short-run the inputs are substitutes and the price effects are highly inelastic. Overshooting occurs with respect to labour and material demands in the short-run since the demand for capital responds very little to output expansion. Returns to scale are also estimated in this cost of adjustment model. Bell Canada exhibits increasing returns to scale initially and then decreasing returns such that on average there are constant returns to scale with a scale elasticity of 1.08.     

The causality between FDI and sector-specific production in Turkey: evidence from threshold cointegration with regime shifts

This article considers bidirectional nonlinear cointegration relation between FDI and industrial output in Turkey. The data cover the monthly period 2005:1–2013:10 for the time series of total industrial production, 36 sub-industrial sectors’ production and FDI. Following nonlinear threshold cointegration and VECMs, the article yields that (i) total industrial production and nine sub-industrial productions have positive long-run impact on FDI with significant error corrections, (ii) six sub-industrial productions have short-term influence on FDI, (iii) FDI has long-run positive impulse on total industrial production and nine sub-industrial productions with some significant error corrections and (iv) FDI affects four sub-industrial productions in the short run as well as in the long run. The results of VECMs from (i) also reveal that the all short-term adjustment parameters are found significant and powerful in 10 typical regimes (Regime-1s) and in 5 extreme regimes (Regime-2s). Finally, the outcome of VECMs from (iii) yields that short-term adjustment parameters are found significant and powerful in two typical regimes and in four extreme regimes. Eventually, considering FDI’s positive impact in the short and long run, this article suggests that policymakers promote specifically the FDI inflows to the sectors of intermediate goods, manufacture of beverages, manufacture of rubber and plastic and manufacture of other nonmetallic mineral products.     

Ten-year forecasts of real stock price changes

This paper provides the strongest evidence to-date on the predictability of real stock prices over long horizons. Ex ante forecasts account for over two-thirds of the variation of the growth rate of real stock prices over ten year spans from 1940 through 2001. The paper forecasts negative growth rates of real stock prices over the next ten years. This bearish long-run outlook is buttressed by the long-run relationship between the growth rates of real stock prices, inflation, dividends, and productivity.

Fractional integration and business cycle features

We show in this article that fractionally integrated univariate models for GDP lead to a better replication of the main business cycle characteristics. We firstly show that the business cycle features are clearly affected by the degree of integration as well as by the other short run (AR, MA, etc.) components of the series. Then, we model the real GDP in the UK and the US by means of fractionally ARIMA (ARFIMA) model, and show that the time series can be specified in terms of this type of model with orders of integration higher than one but smaller than two. Comparing the ARFIMA specifications with those based on ARIMA models, we show via simulations that the former better describe the business cycles features of the data.Jel classification: C12, C15, C22The authors want to thank two anonymous referees for wise remarks.

Entrepreneurs' capital accumulation behavior and long-run equilibrium

The purpose of this paper is to derive some interesting results on long-run equilibrium by considering entrepreneurs' capital accumulation behavior explicitly. Our framework is a two class, two production sector model in order to analyze the dynamic stability properties in the cases of Kaldor's saving assumption and Pasinetti's saving assumption. We shall introduce a further adjustment mechanism: the speeding up (slowing down) of capital accumulation in that sector in which the rate of profit is higher (lower).
