An important challenge in economics is to explain what causes firms to exit. The standard answer is low profitability. This answer leaves, however, open a number of questions as profitability partly depends on factors that are difficult to measure, for example, demand conditions, efficiency and market structure. In addition, due to market imperfections and regulations, other variables may also play a role in explaining exits.
In the empirical literature, several variables have been used in order to explain exits. These include plant size, see Mata, Portugal and Guimarães (1995); capital intensity, see Boeri and Bellmann (1995); financial leverage, see Dimitras, Zanakis and Zopounidis (1996); productivity, see Olley and Pakes (1996); capital vintage, see Salvanes and Tveterås (2004), and demand shocks, see Foster, Haltiwanger and Syverson (2005). The purpose of the present paper is to identify, through a structural microeconometric model with heterogeneous firms, imperfect competition and adjustment costs, some key determinants of exit behavior.
