Evidence on purchasing power parity from univariate models: the case of smoot...
Recent research has found that trend-break unit root tests derived from univariate linear models do not support the hypothesis of long-run purchasing power parity (PPP) for US... -
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... -
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,... -
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... -
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... -
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)... -
Stylized facts of daily return series and the hidden Markov model (replicatio...
In two recent papers, Granger and Ding (1995a,b) considered long return series that are first differences of logarithmed price series or price indices. They established a set of... -
A nonlinear approach to US GNP (replication data)
A univariate nonlinear model is estimated for US GNP that on many criteria outperforms standard linear models. The estimated model is of the threshold autoregressive type and... -
Common Trends and Common Cycles (replication data)
The existence of a serial correlation common feature among the first differences of a set of I(1) variables implies the existence of a common cycle in the...
