Testing for heteroskedasticity in fixed effects models
(Elsevier, 2014-01)
We derive tests for heteroskedasticity after fixed effects estimation of linear panel models. The asymptotic results are based on a ‘large N–fixed T’ framework, where the incidental parameters problem is bypassed by utilizing ...
Non-perturbative fixed points and renormalization group improved effective potential
(Elsevier B.V., 2014-12-12)
The stability conditions of a renormalization group improved effective potential have been discussed in the case of scalar QED and QCD with a colorless scalar. We calculate the same potential in these models assuming the ...
Fixed assets-infrastructure and financial health in hospitality industry: A chaotic effect in emerging markets
The influence of property, plant and equipment (Fixed Assets) and the quality of infrastructure on return was analyzed in the hospitality industry in emerging markets. The analysis unit was Colombia, a member of the CIVETS ...
Correcting the fixed-effect estimator for endogenous switching
(2007-07-20)
In this paper, we propose a two-step estimator for panel data models in which a binary covariate is endogenous. In the first stage, a random-effects probit model is estimated, having the endogenous variable as the left-hand ...
QCD fixed points: Banks-Zaks scenario or dynamical gluon mass generation?
(2017-01-30)
Fixed points in QCD can appear when the number of quark flavors (Nf) is increased above a certain critical value as proposed by Banks and Zaks (BZ). There is also the possibility that QCD possess an effective charge ...

The effects of fixed-term contracts on workers in colombia
(Facultad de Ciencias Economicas - Universidad Nacional de Colombia, 2014-08-31)
This paper studies the effects of fixed-term contracts on workers. Specifically,the paper analyzes their impact on wages and on satisfaction levels. Regulationsgoverning fixed-term and indefinite contracts in Colombia and ...
The effect of clitoral stimulation post fixed-time insemination in Bos indicus beef cattle

Air-drying of fresh and osmotically pre-treated pineapple slices: Fixed air temperature versus fixed slice temperature drying kinetics
(Marcel Dekker Inc, 2001-01-01)
In this investigation, the air drying characteristics of fresh and osmotically pre-treated pineapple slices in a tray dryer were studied under different operating conditions. The air velocity varied from 1.5 to 2.5 m/s and ...
