and quantity indexes are calculated separately for components of GDP and therefore the difference between nominal GDP and real GDP growth is only approximately equal to the change in the GDP price index. With fixed-weights, the GDP deflator is defined as the ratio of nominal to real GDP and hence the gap between nominal and real GDP growth rates is precisely equal to the growth rate in the GDP ...

this study employs a gmdh neural network model, which has high capability in recognition of complicated non-linear trends especially with small samples, for modeling and predicting iranian gdp growth. first a fundamental model containing 7 independent variables together with dependent variable is designed and then by using deductive process and omission of one variable at a time, a total of 18 ...

We replicate Reinhart and Rogoff (2010a and 2010b) and find that coding errors, selective exclusion of available data, and unconventional weighting of summary statistics lead to serious errors that inaccurately represent the relationship between public debt and GDP growth among 20 advanced economies in the postwar period. Our finding is that when properly calculated, the average real GDP growth...

The argument that human society can decouple economic growth-defined as growth in Gross Domestic Product (GDP)-from growth in environmental impacts is appealing. If such decoupling is possible, it means that GDP growth is a sustainable societal goal. Here we show that the decoupling concept can be interpreted using an easily understood model of economic growth and environmental impact. The simp...

Recent developments in entrepreneurship suggest a causal link between entrepreneurial activity and economic growth: entrepreneurship precedes economic growth. A positive effect from entrepreneurship on economic development in advanced, innovation-driven economies in the most recent decades is often maintained. Self-employment is one of the most common indicators of entrepreneurship. The present...
