Demografia das empresas e sua expectativa de vida no Rio Grande do Norte

Abstract

In the current economic scenario, Micro and Small Enterprises (MSE’s) account for 99% of the companies in the Brazil and more than half of the jobs with a formal contract, thus being vital for the economy. However, several studies indicate that MSE's have a high mortality rate in the first years of life, both in Brazil and in other countries. Therefore, the present study has as general purpose to determine the life expectancy, by economic sector and time of creation, of the Micro and Small Enterprises of Rio Grande do Norte, and, for this, it will have as main intent to construct a board business life. The use of indicators of mortality and life expectancy of companies is a very useful tool for planning, policy decisions and actions in the sectors: private, public, Academic and social. For this goal, data of creation and mortality of companies in Rio Grande do Norte were used from the Federal Revenue Service, provided by SEBRAE / RN, in the years 2005, 2006 and 2007, and accompanied until the year 2009. Based on this information, an estimate of mortality in future ages was made using Brass's Logito method, based on the model tables of Mexican companies created in 2014 by the National Institute of Statistics and Geography of Mexico (INEGI). Finally, the preliminary results show the existence of Mexican model tables with similar mortality rates to the ones found in Rio Grande do Norte for the 2005 companies cohort, therefore making it possible to apply the Logito de Brass to the Estimation of future ages and, consequently, the creation of the board and calculation of expected business life.
