Cox (1972) introduced a semi-parametric model for survival
time which could add covariates but not impose a parametric form
for the distribution of survival times. The Cox proportional hazard
rate can be written as follows:
Immigrant-started new ventures face the liability of ethnicity because of their founders’ disadvantaged
immigration status. It is extremely difficult for them to acquire human, social and
financial capital and
access market in founders’ country of residence to survive. This study empirically examines the survival
of immigrant-started new ventures. We
find that an early internationalization strategy could enhance
those ventures’ survival and that immigration status moderates the effect of an early internationalization
strategy on their survival. This study contributes to both immigrant and international entrepreneurship
literature. Managerial and policy implications are also discussed.
