A general test for time dependence in parameters (replication data)
A new test for time-dependent parameters is proposed. The Trig-test is based on a trigonometric expansion to approximate the unknown functional form of the variation in the... -
Convergence in European GDP series: a multivariate common converging trend–cy...
Convergence in the gross domestic product series of five European countries is empirically identified using multivariate time series models that are based on unobserved... -
On detrending and cyclical asymmetry (replication data)
This paper considers the issue of testing for symmetry of the business cycle. It is demonstrated that findings of symmetry should be interpreted with caution since tests tend to... -
Long-range dependence in Spanish political opinion poll series (replication d...
This paper investigates the time series properties of partisanship for five political parties in Spain. It is found that pure fractional processes with a degree of integration,... -
Time irreversibility and EGARCH effects in US stock index returns (replicatio...
In this paper we suggest using a modified version of the time reversibility (TR) test of Chen, Chou and Kuan (2000) as a complementary diagnostic test for time series models.... -
Censored latent effects autoregression, with an application to US unemploymen...
A model is proposed to describe observed asymmetries in postwar unemployment time series data. We assume that recession periods, when unemployment increases rapidly, correspond... -
Modelling the trend and seasonals within an AIDS model of the demand for alco...
The argument that is put forward in this paper is that failure to represent stochastic trend and stochastic seasonality in an AIDS model leads to a misspecified and possibly... -
Trend-stationary GNP: evidence from a new exact pointwise most powerful invar...
There has been a substantial debate whether GNP has a unit root. However, statistical tests have had little success in distinguishing between unit-root and trend-reverting... -
Non-linear error correction and the UK demand for broad money, 1878-1993 (rep...
In this paper we reconsider an error-correction model of UK broad money demand by Ericsson, Hendry and Prestwich. Their model is non-linear in both variables and parameters, and... -
Descriptive econometrics for non-stationary time series with empirical illust...
Recent work by the author on methods of spatial density analysis for time series data with stochastic trends is reviewed. The methods are extended to include processes with... -
Bounds testing approaches to the analysis of level relationships (replication...
This paper develops a new approach to the problem of testing the existence of a level relationship between a dependent variable and a set of regressors, when it is not known... -
Clusters of attributes and well-being in the USA (replication data)
Using ARIMA models and entropy, the dynamic evolution of several functions of aggregate income and other attributes of well-being is analysed for statistical similarity in order... -
Output and inflation in the long run (replication data)
Cross-country regressions explaining output growth often obtain a negative effect from inflation. However, that result is not robust, due to the selection of countries in... -
Tests for multiple forecast encompassing (replication data)
In the evaluation of economic forecasts, it is frequently the case that comparisons are made between a number of competing predictors. A natural question to ask in such contexts... -
Another look at Swedish business cycles, 1861-1988 (replication data)
The linearity of nine long Swedish macroeconomic time series, whose business cycle properties were discussed by Englund, Persson, and Svensson (1992), is tested and rejected for... -
The error structure of time series cross-section hedonic models with sporadic...
When estimating hedonic models of housing prices, the use of time series cross-section repeat sales data can provide improvements in estimator efficiency and correct for... -
Estimating the LQAC model with I(2) variables (replication data)
This paper derives a method for estimating and testing the Linear Quadratic Adjustment Cost (LQAC) model when the target variable and some of the forcing variables follow I(2)... -
Detecting periodically collapsing bubbles: a Markov-switching unit root test ...
This paper addresses the problem of testing for the presence of a stochastic bubble in a time series in the case that the bubble is periodically collapsing so that the asset... -
A Monte Carlo study of the forecasting performance of empirical SETAR models ...
In this paper we investigate the multi-period forecast performance of a number of empirical self-exciting threshold autoregressive (SETAR) models that have been proposed in the... -
The time-varying behaviour of real interest rates: a re-evaluation of the rec...
A time-varying parameter model with Markov-switching conditional heteroscedasticity is employed to investigate two sources of shifts in real interest rates: (1) shifts in the...
