We show that a one-sector real business cycle model with mild increasing returns-to-scale, variable capital utilization and saddle-path stability is able to produce qualitatively realistic business cycles driven solely by disturbances to government purchases. Due to an endogenous increase in labor productivity, a positive spending shock can lead to simultaneous increases in output, consumption,...

The empowerment of small-medium scale industries must be carried out thoroughly through the provision of business development opportunities to the greatest extent so as to be able to increase the role and potential of the industries. The purpose of this study was to analyze the internal influence of the human resources competencies on technology and the organizational readiness to the level of ...

   Evaluate the performance of companies on the Stock Exchange using non-parametric methods is very important. DEA and DEA-R with the strategies for piecewise linear frontier production function and use of available data, assess the stock company. In this study, using a neural network algorithm DEA and DEA-R is suggested to classify the first companies in the stock exchange; Secondly, using the...

Due to the complexity of financial markets and specialization of investment, the investors in financial markets need tools, methods and models by which they can choose the best investment and the most appropriate portfolios. Fama-French Five-Factor Model (FFFFM) is one of the newest methods among various methods for financial asset pricing and prediction of stock returns. The main aim of this r...

Differences between the concepts of returns to size and returns to scale are systematically reexamined in this paper. Specifically, the relationship between returns to scale and size are examined through the use of the envelope theorem. A major conclusion of the paper is that the level of abstraction in applying a cost function derived from a homothetic technology within a relevant range of the...

We introduce increasing returns to scale into an otherwise standard New Keynesian model with capital, and study the determinacy and E-stability of Taylor-type interest rate rules. With very mild increasing returns supported by empirical research, the conventional wisdom regarding the design of interest rate rules can be overturned. In particular, the “Taylor principle” no longer guarantees eith...

Abstract In this study, variable returns to scale (VRS) data envelopment analysis was integrated into the Taguchi approach optimize ternary additives for expansive soil enhancement. The selected were sawdust ash (SDA), quarry dust (QD) and ordinary Portland cement (OPC). set as input variables while multiple responses obtained from experiments performed with orthogonal array output variables. E...
