The study aimed to measure the effects of the Covid-19 epidemic on global growth rates in vital sectors around the world specially – Agriculture – Construction – Manufacturing – Mining -& Transport, because it is the sectors that most to the formation of the GDP and has been directly affected by the Corona pandemic, the study proved too that the Corona virus epidemic has affected, to varying levels and degrees, the economies of the countries of the world. In most different sectors, especially developing countries, but the regional and local impact of the COVID-19 crisis was highly variable, with important economic and social dimensions in addition to the implications for crisis management and political responses to deal with it... Therefore, this paper takes an in-depth look at the impact. Linked to the COVID-19 crisis, the global growth rate at the time of lockdown, which led to the emergence of very difficult fateful challenges in many economies in the world, especially the developed ones, as well as the surprise of the emergence of emerging economies that surfaced and showed positive and significant recovery in growth rates for many of their sectors Vitality at a time in which a number of advanced economies surprised us by achieving a negative growth rate in light of their enormous economic potential, so we were interested to choose a heterogeneous package from the countries of the world (9 countries )to represent the diversity required for the different impact of the Corona virus on the different world economies and the expectations which the world economy will be appear in the global growth rates after the end of this pandemic.. So we exclusively selected 9 countries: Egypt, Saudi Arabia, Ethiopia, India, China, Germany, France, the United States of America and Australia, as examples. Stratification on this research

Forecasts of long-run economic growth are critical inputs into policy decisions being made today on the economy and the environment. Despite its importance, there is a sparse literature on long-run forecasts of economic growth and the uncertainty in such forecasts. This study presents comprehensive probabilistic long-run projections of global and regional per-capita economic growth rates, comparing estimates from an expert survey and a low-frequency econometric approach. Our primary results suggest a median 2010–2100 global growth rate in per-capita gross domestic product of 2.1% per year, with a standard deviation (SD) of 1.1 percentage points, indicating substantially higher uncertainty than is implied in existing forecasts. The larger range of growth rates implies a greater likelihood of extreme climate change outcomes than is currently assumed and has important implications for social insurance programs in the United States.

Despite huge global growth rates and a rapidly increasing importance ofIslamic banking and finance, research in this area still needs to be classified asnascent. Recent economic events have led to an increasingly critical attitudetowards the conventional banking and finance system, whereas Islamic banking isconsidered to be an ethical alternative not only in Muslim economies but alsoprogressively in the “western” world. As their business models have their originsin religious and ethical ideals, Islamic banks struggle to observe the foundationalShariah principles while simultaneously meeting applicable guidelines such asBasel III and flexibly adapt to the ever changing customer demands. Due to theincreasing importance of Islamic banking and finance, this article aims to analyseand summarise various aspects of current research and sets out to identify both,congruence and inconsistencies between the implied promise of an “ethical”alternative and the actual market.


This chapter delves deeper into the controversial trade-growth debate – controversial because empirical evidence has provided a wide variety of findings, although one of the stylized facts of global growth is that economies which have opened-up for trade have grown very strongly. The focus is China, the regional and international trade-giant, with an objective of analyzing the impact of trade on economic growth. The motivation of this chapter is due to a number of reasons. First, as stated above, while theoretical economists broadly converge to the agreement that trade has positive growth effects (with various conditionalities), empirical findings have been conflicting. Second, these conditions and other important issues surrounding trade openness are important and must be adequacy explored. Third, the Chinese (or Asian economies) data provides the best grounds of experimenting on both trade and growth, especially in the era when they dominate both world trade and growth rates. And finally, this chapter is an application of the extension developed by Rao and Singh (2007) for estimating the impact of trade openness on economic growth of China.
