The ratio estimator of the markup is output elasticity for a flexible input to that input’s cost share in total revenue. We highlight identification and estimation issues pertaining this estimator, when firm-level prices are not observed. If revenue used place elasticity, then profit maximization implies identically equal one, thus uninformative about markups. Concerning elasticities: with only...

Abstract The strong ellipticity condition plays an important role in nonlinear elasticity and in materials. In this paper, we define M-eigenvalues for an elasticity tensor. The strong ellipticity condition holds if and only if the smallest M-eigenvalue of the elasticity tensor is positive. If the strong ellipticity condition holds, then the elasticity tensor is rank-one positive definite. The e...

Complex cloud services rely on various IaaS, PaaS, and SaaS cloud offerings. Fast (re)deployment and testing cycles, and the rapidity of changes of various dependent infrastructures and services, imply a need for continuous adaptation. Although software-based elasticity control solutions can automate various decisions through intelligent decisionmaking processes, in many cases, such adaptation ...

BACKGROUND AND OBJECTIVES Platelet-rich plasma (PRP) is an autologous concentration of human platelets contained in a small volume of plasma and has recently been shown to accelerate wound healing and rejuvenate aging skin. The current study was conducted to determine whether there are additional effects of PRP combined with fractional laser therapy. MATERIALS AND METHODS Twenty-two Korean wo...

This paper studies the dynamic behavior of price elasticity and its effects on the overall profit. Although price elasticity has a significant effect on sales, its dynamics have not been examined so far in pricing models. In this paper, a simple pricing model is suggested in which, price elasticity is considered dynamic. The suggested pricing model is concerned with a monopolist that its object...

Supply equations for sawlog and pulpwood were developed with a panel of data from 102 Norwegian municipalities, observed from 1980 to 2000. Static and dynamic models were estimated by cross-section. time-series and panel data methods. A static model estimated by first differencing gave the best overall results in terms of theoretical expectations, pattern or residuals. prediction accuracy and p...
