Do firms share the same functional form of their growth rate distribution? A statistical test
2014
We introduce a new statistical test of the hypothesis that a balanced panel of firms have the same growth rate distribution or, more generally, that they share the same functional form of growth rate distribution. We applied the test to European Union and US publicly quoted manufacturing firms data, considering functional forms belonging to the Subbotin family of distributions. While our hypotheses are rejected for the vast majority of sets at the sector level, we cannot rejected them at the subsector level, indicating that homogenous panels of firms could be described by a common functional form of growth rate distribution.
Ecological determinants of smart home ecosystems: A coopetition framework
2021
Abstract Nearly every industry classification is experiencing slow growth and increasing concentration. Seldom do researchers have an opportunity to observe an emerging industry segment with as much promise as the smart home ecosystem, an exponentially growing industry. The study presents a novel approach using industry life cycle model and a coopetition framework to understand the process of the ecosystem development. Building on recent literature suggesting companies that purposefully match strategy to life cycle stage, the paper describes the strategic motivations and critical factors involved in the competition-based evolution of smart home ecosystems from early to growth phases, leadin…
Do Firms Share the Same Functional Form of Their Growth Rate Distribution? A New Statistical Test
2011
We propose a hypothesis testing procedure to investigate whether the same growth rate distribution is shared by all the firms in a balanced panel or, more generally, whether they share the same functional form for this distribution, without necessarily sharing the same parameters. We apply the test to panels of US and European Union publicly quoted manufacturing firms, both at the sectoral and at the subsectoral NAICS levels. We consider the following null hypotheses about the growth rate distribution of the individual firms: i) an unknown shape common to all firms, with all the firms sharing also the same parameters, or with the firm variance related to its firm size through a scaling rela…
