Abstract The internationalization of firms from emerging markets has been studied mainly from the perspective of large firms. Smaller and younger international firms based in emerging markets suffer from underrepresentation in the literature. This study sheds light on the internationalization of emerging market SMEs, focusing on Colombian textile and apparel exporters. Using mixed research methods, it illustrates the role of firm age in influencing internationalization strategy. It examines 1165...

The bivariate Weibull distribution is very important in both reliability and survival analysis. The dependence for these kind of problems has been gaining great importance in recent years. In the literature, there are algorithms to generate univariate Weibull distributions and bivariate Weibull distributions with independent marginal distributions. In this paper, we present an algorithm to generate dependent bivariateWeibull failure times using a copula representation for the bivariate Weibull r...

The traditional methodology assumes independence between competing failure modes to estimate the reliability function, but recent studies have shown that when this assumption is incorrectly assumed, usually gives pessimistic estimates. This paper intends, through a simulation study, to explore the effect caused by such a situation in the cases of two competing lognormal failures and two competing Weibull failures. It is appreciated from the results that, when the dependence is ignored, there are...

La metodologia tradicional asume independencia entre los modos de falla concurrentes (“competing risks”) para la estimacion de la funcion de confiabilidad, pero estudios recientes advierten sobre los posibles errores de estimacion que dicho supuesto conlleva, cuando realmente existe dependencia entre los modos de falla. Este artiulo pretende, a traves de un estudio de simulacion, explorar el efecto causado por dicha situacion, en los casos de dos modos de falla lognormales y de dos modos de ...
