The paper presents empirical results on an import prices equation to the case of the small open Hellenic economy, during her course to the European Monetary Union, in the 1980s until mid-1990s. The analysis employs cointegration theory to examine the long-run co-movements of prices, effective...

Using non-linear unit root tests this paper investigates non- stationarity of real GDP per capita for seven OECD countries over the period 1900-2000. Non-linear unit root tests are more powerful than traditional ADF statistics in rejecting the null unit root hypothesis. To this end we adopt a...

We use the well known USDA dataset of real exchange rates to address the question of whether PPP holds for agricultural commodities. Both unit root tests and the recently proposed more powerful class of panel unit root tests, which take into account cross-section correlation across the units in...

The study presents an analysis of the stochastic nature of the gross domestic product of Mexico for the period 1900-2001. Several specifications to test for the existence of unit roots are presented. The conventional tests, Dickey Fuller, Augmented Dickey Fuller and Phillips Perron, indicate...

Maintaining sustainable fiscal policy has been increasingly important in the scope of economists and the policy makers as the key requirement of macroeconomic stability and sustainability of an economy. Without exception, the issue of fiscal sustainability also being in the spotlight for the...

Several recent papers conclude that U.S. real GDP is trend stationary, implying that all shocks are transitory and long run path is deterministic. These inferences fail to take into account two problems: the distortion of test size in finite samples due to data-based model selection, and the...

In this paper we consider bayesian semiparametric regression within the generalized linear model framework. Specifically, we study a class of autoregressive time series where the time trend is incorporated in a nonparametrically way. Estimation and inference where performed through Markov Chain...

Sumario El estudio utiliza las herramientas de series tiempo como las pruebas de raíz unitaria y corte estructural para analizar las series de los determinantes de la Inversión Extranjera de Cartera (IEC) y la misma IEC. Varias series fueron consideradas para el análisis de la IEC, entre los...

In this paper we extend the macroeconometric model developed in Bagnai (2004) by linking it to a submodel for the Japanese economy, and we utilize this extended model to investigate several hypotheses of reduction in the US twin deficits. The Japanese submodel is specified and estimated along...
