This paper provides empirical evidence on links between the productivity of Portuguese firms and a number of policy variables in Portugal. The analysis is based on a census of Portuguese manufacturing companies, covering more than 40,000 firms between 2006 and 2011. The results suggest that a number of these variables matter for firm performance, including the number of procedures required to start a business, a more extensive coverage of collective wage bargaining agreements, the tax burden, tax compliance costs and the number of procedures required to enforce a contract.
