Purpose -This paper aims to analyze the industry characteristics and the strategic behavior of companies that affect zombie companies.Theoretical framework -The study was based on the structure-conductperformance paradigm derived from industrial organization theory, because it allows us to explain a firm's results through behavior influenced by external and internal factors.Design/methodology/approach -For the data analysis, the corrected standard errors technique was used on a data set of 99 companies registered in the Mexican Stock Exchange during the period from 2013 to 2017.Findings -Among the main findings, it is evident that strategic behavior affects zombie companies. On the other hand, we found that market competitiveness negatively affects zombie companies, while barriers to entry positively affect them. The results allow us to identify similarities with and differences from other zombie firms in the world, based on the Latin American environment and its institutional policy.Practical & social implications of the research -Zombie firms have a negative connotation; however, they may become necessary to keep businesses operational in developing countries. Also, the study may provide a background to regulations on firm bankruptcy.Originality/value -The most important contribution is that this is a pioneering investigation that analyzes strategic behavior and its effect on zombie companies. Also, this may be one of the first studies to examine these companies in Latin America, making it possible to identify differences from zombie firms in the rest of the world due to environmental elements such as institutional policy.
