There are many studies that look into the relationship between public debt and economic growth. It is hard to find, however, research addressing the role of corruption between these two variables. Noticing this vacancy in current literature, we strive to investigate the effect of corruption on the relationship between public debt and economic growth. For this purpose, the pooled ordinary least ...

In most gravity model applications, general equilibrium effects are disregarded altogether or ”controlled for” by country or country-time fixed effects, and the parameter estimates on observable trade cost variables are falsely interpreted as reduced-form marginal effects rather than only direct effects of such variables on trade. This paper proposes an empirical approach which employs panel da...

A large number of descriptors were employed to characterize the molecular structure of 53 natural, synthetic, and environmental chemicals which are suspected of disrupting endocrine functions by mimicking or antagonizing natural hormones and may thus pose a serious threat to the health of humans and wildlife. In this work, a robust quantitative structure-activity relationship (QSAR) model with ...

Traffic problems are the most prominent urban dilemmas, especially during recent years, since the capacity of old traffic arteries don’t meet the increasing volume of population and vehicles, therefore, adopting some measures in order to enhance the capacity of existing roads has been placed on the agenda of urban managers. Changing the existing intersections to over changes is one of these met...

We provide evidence that democracy has a significant and robust positive effect on GDP. Our empirical strategy relies on a dichotomous measure of democracy coded from several sources to reduce measurement error and controls for country fixed effects and the rich dynamics of GDP, which otherwise confound the effect of democracy on economic growth. Our baseline results use a linear model for GDP ...

Recent studies find that China exported goods of relatively high product sophistication, which are not compatible to China’s economic development level. In this paper we use detailed product-level and firm-level data to examine the determination of product sophistication level of Chinese exports in the period 1998-2005, in particular the role of foreign firms. In our study we distinguish betwee...

What are the major challenges, fault lines, and potential adversities (these terms are used synonymously) that China’s economic development will encounter over the next decade?1 How severely will China’s overall economic performance be affected if these adversities occur separately or in clusters? This book addresses these key questions. We deliberately concentrate on what might go seriously aw...

In this paper, first we identify the destruction ways of concrete constructions and the benefits of waste management and the plans to recycle the concrete debris were investigated and it was concluded that the existence of plans to recycle the concrete debris could lead to big economic save ups and by recycling these debris we can create affordable ways for concrete making centers. By the way, ...
