This paper investigates the relationship between total energy consumption and GDP in six countries of the Middle East , including Iran,Pakistan,Saudi Arabia,Oman,Bahrain and the United Arab Emirates. The data are annual and spanning the period 1980-2012.We employed Hsiao’s (1981) methodology to examine causality relation between total energy consumption and GDP.The empirical findings show a uni...

This paper uses scale-independent indicators to explore the Chinese national and regional innovation systems during economic transition. Our perception of an innovation system is frequently informed by conventional indicators based on linear assumptions while actually innovation systemsmay behave differently. Scale-independent indicators characterize non-linearpropertiesof an innovation system....

We analyse the Granger causal relationships between foreign direct investment (FDI) and GDP in a sample of 31 developing countries covering 31 years. Using estimators for heterogeneous panel data we find bi-directional causality between the FDI-to-GDP ratio and the level of GDP. FDI has a lasting impact on GDP, while GDP has no longrun impact on the FDI-to-GDP ratio. In that sense FDI causes gr...

We investigate the impact of large floods on civil conflict in a sample of 125 countries between 1985 and 2009, employing GDP growth as a potential transmission channel. We instrument for floods and control for potential spatial and temporal dependency of civil conflict. We find that floods increase the probability of conflict incidence through their effect on GDP growth.

â â â  â â â â  abstract â  as the chances of a successful conclusion to the doha round of trade liberalization under the wto become increasingly problematic, so the pace of negotiating local free trade agreements (ftas) is increasing. according to the wto report, countries in the asia-pacific region are “consolidating their drive towards regionalism at an accelerated pace”. after the trade...

 Beijing’s industrial structure is service-oriented with a high degree of economic openness, and GDP has maintained rapid growth. This paper analyzes the international financial crisis and the impact of China’s anti-crisis policies on Beijing’s economic development as well as its transmission mechanism. Impact Index (excluding seasonal factors) and ARMA Model are employed in the empirical...

This paper reviews and documents methodology for fitting hidden Markov switching models to New Zealand GDP data. A primary objective is to better understand the utility of these methods for modelling growth and volatility regimes present in the New Zealand data and their interaction. Properties of the models are developed together with a description of the estimation methods, including use of t...

Background: A dramatic increase in healthcare expenditures is a major health policy concern worldwide. Understanding factors that underlie the growth in healthcare expenditures is essential to assist decision-makers in finding best policies to manage healthcare costs. We aimed to examine the determinants of healthcare spending in Iran over the periods of 1978-2011. Methods: A time series ana...

Microtubule growth proceeds through the endwise addition of nucleotide-bound tubulin dimers. The microtubule wall is composed of GDP-tubulin subunits, which are thought to come exclusively from the incorporation of GTP-tubulin complexes at microtubule ends followed by GTP hydrolysis within the polymer. The possibility of a direct GDP-tubulin incorporation into growing polymers is regarded as ha...
