The aim of the paper is to compare the forecasting performance of a class of state-dependent autoregressive (SDAR) models for univariate time series with two alternative families of nonlinear models, such as the SETAR and the GARCH models. The study is conducted on US GDP growth rate using...

This paper analyzes the evolution of the Lebanese GDP growth rate over the period 1970- 2019 by estimating two kinds of switching models: The Smooth Transition Autoregressive (STAR) model and the model of the Markov process. These models show, on the one hand, asymmetries in the evolution of GDP...

This paper examined the long memory features of GDP per capita data before the global financial crisis, using a sample of 26 African countries. The study employed fractional integration and tested the stability of the differencing parameter across the sample period for each country. The results...

This paper studies long economic series to assess the long-lasting effects of pandemics. We analyze if periods that cover pandemics have a change in trend and persistence in growth, and in level and persistence in unemployment. We find that there is an upward trend in the persistence level of...

We conduct an out-of-sample backtesting exercise of Growth-at-Risk (GaR) predictions for 24 OECD countries. We consider forecasts constructed from quantile regression and GARCH models. The quantile regression forecasts are based on a set of recently proposed measures of downside risks to GDP,...

Can a growing welfare state induce a regime switch in the growth rate of an economy? This paper constructs a dynamic political economy model of economic growth and the welfare state in which both variables are non-linearly related and jointly endogenous. Using a Markov switching framework over...

The impact of population growth on the environment is an issue that is highly debated yet comparatively under-researched empirically. This is true despite a vast number of published articles on the link between population and environmental changes speculating on the sign of the environment...

The central point of this paper is that both – internal and external – equilibria ought to be involved in the estimation of potential output. If only the data on inflation, unemployment rate and wages are used for its evaluation, no certainty exists that such a level will correspond to a...

This paper investigates the Keynesian Relations and Education Expenditure in Saudi Arabia during the period (1970-2012) for real Oil GDP and Non Oil GDP. Keynesian Relations investigated that fundamental economic growth is validity to the education growth. In the previous studies have been...

This study aims to provide time series evidence of the economic growth pattern of Greece and explains the hidden impacts of its financial liberalization process since 1960, in terms of the links between trade and gross domestic output. Using time series data covering the period 1960-2009, the...
