New Evidence of the Real Interest Rate Parity for OECD Countries Using Panel Unit Root Tests with Breaks
2006
This paper tests for real interest parity (RIRP) among the nineteen major OECD countries over the period 1978:Q2-1998:Q4. The econometric methods applied consist of combining the use of several unit root or stationarity tests designed for panels valid under cross-section dependence and presence of multiple structural breaks. Our results strongly support the fulfillment of the weak version of the RIRP for the studied period once dependence and structural breaks are accounted for.
Is the environmental performance of industrialized countries converging? A ‘SURE’ approach to testing for convergence
2008
In this paper, we test for convergence in the environmental performance of a sample of OECD countries, with data ranging from 1971 to 2002. First, we use Data Envelopment Analysis (DEA) to compute two environmental performance indicators (EPIs) in the production theory framework. Second, we propose the use of a sequential multivariate approach to test for convergence in environmental performance. These tests allow us to reconcile the time series literature with the cross-sectional dimension, which is basic when testing for convergence in regional blocs. The SURE technique is used, which allows for the existence of correlations across the series without imposing a common speed of mean revers…
Hysteresis vs. natural rate of unemployment: new evidence for OECD countries
2004
Abstract The paper tests hysteresis effects in unemployment using panel data for 19 OECD countries. We apply a sequential procedure based in two multivariate augmented Dickey-Fuller test (ADF)-type panel unit root tests in a SURE framework. We strongly reject the joint null of hysteresis and find that only seven countries present evidence of hysteresis.
Testing the stationarity of interest rates using a SUR approach
1998
Abstract Using data on average yields to maturity of German bonds with different time to maturity it is shown that the time series contain a unit root if the standard augmented Dickey–Fuller test is applied separately to each series. To improve the power of the test we carried out a recently developed approach, estimating the regressions for each time to maturity jointly using a seemingly unrelated regressions approach.
50 years of capital mobility in the eurozone: breaking the Feldstein-Horioka puzzle
2021
AbstractThis paper assesses capital mobility for the Eurozone countries by studying the long-run relationship between domestic investment and savings for the period 1970-2019. Our main goal is to analyze the impact of economic events on capital mobility during this period. We apply the cointegration methodology in a setting that allows us to identify endogenous breaks in the long-run saving-investment relationship. Precisely, the breaks coincide with relevant economic events. We find a downward trend in the saving-investment retention since the 70s for the so-called “core countries”, whereas this trend is not so evident in the peripheral, where the financial and sovereign crises have had a …
TESTING FOR REAL INTEREST RATE PARITY USING PANEL STATIONARITY TESTS WITH DEPENDENCE: A NOTE*
2009
In this paper we test for real interest parity (RIRP) among the 19 major OECD countries over the period 1978:Q1–2006:Q1 using both short- and long-run definitions of interest rates. Once the independence hypothesis is rejected among these series, we test for RIRP using panel data unit root and stationarity tests based on common factor models that allow for pervasive forms of dependence. Our results indicate that there is no evidence in favor of the weak version of the RIRP since one of the common factors that have been estimated is non-stationary.
Energy use–GDP deterministic cointegration: progress towards EU-15 Kyoto targets
2015
This article examines whether the energy consumption–GDP relationship is in long-term equilibrium for EU-15 countries. Unlike many previous works, we apply a nonlinear unit root test introduced by Kapetanios et al. (2003a) and extended by Chong et al. (2008) that identifies not only deterministic cointegration, but also the stronger concept of stochastic cointegration. The results yield a clear pattern: Austria, Denmark, Italy, the Netherlands, Portugal and Spain must achieve greater emissions reductions between 2009 and 2012 to reach their respective Kyoto targets.
Threshold Effects in the US Budget Deficit
2003
We contribute to the debate on whether the large U.S. federal budget deficits are sustainable in the long run. We model the U.S. government deficit per capita as a threshold autoregressive process. We find evidence that the U.S. budget deficit is sustainable in the long run and that economic policymakers will intervene to reduce per capita deficit only when it reaches a certain threshold.
Unemployment Hysteresis in Transition Countries: Evidence using Stationarity Panel Tests with Breaks
2008
The authors test hysteresis versus the natural rate hypothesis in unemployment using panel data for transition countries covering the period 1991:1–2003:11.The advantages of the stationarity tests applied is that they exploit the cross-section variations of the series and, additionally, allow for a different number of endogenous breakpoints in the unemployment series. They do not impose independence on the panel members, so that the critical values are simulated based on their specific panel sizes and time periods. The findings stress the importance of accounting for exogenous shocks in the series and give support to the shifting natural-rate hypothesis of unemployment for all the countries…
Total Factor Productivity Convergence Amongst Italian Regions: Some Evidence from Panel Unit Root Tests
2009
Byrne J. P., Fazio G. and Piacentino D. Total factor productivity convergence among Italian regions: some evidence from panel unit root tests. Regional Studies. This paper employs panel unit root tests to investigate convergence in total factor productivity (TFP) among Italian regions. These tests provide an inference valid in the presence of heterogeneity and cross-sectional dependence, and when the cross-sectional dimension is smaller than the time dimension, allowing the investigation of convergence among different subsets of regions. The results add a further dimension to the conventional view on growth dynamics in the Italian peninsula depicting a lack of regional TFP convergence not o…
