• Resumen

  • This thesis consists of three essays organized in three chapters. The common thread is that they are all related to the economics of innovation and to innovation policy. In particular they provide fresh empirical evidence on the allocation and impact of public support to firms’ innovation activities in two different countries. The introduction chapter starts with an overall introduction for the three chapters. Here, the chapter focuses on innovation policy and describes reasons for policy intervention. Afterwards a detailed presentation of the individual research chapters is provided. Chapter 2 examines the relationship between innovation subsidies, innovation effort and productivity in an emerging country, Colombia. It extends the recursive model developed by Crepon-Duguet-Mairesse (CDM) at the first and at the last stage of the model. In order to explicitly model access to innovation subsidies it adds a corresponding equation as the first step of the model. It takes into account, in the last step, the potentially heterogeneous impact of innovation on productivity. Chapter 3 investigates the impact of direct support for innovation over the business cycle in Spain. It examines whether firms that benefit from public support in recessions differ from firms that benefit from it during expansions, whether the impact of public support is smaller in recessions than in expansions or otherwise, and whether these effects vary with the length of the subsidy spell. Chapter 4 explores the determinants of persistence in the use of R&D subsidies in Spain and analyzes the extent to which continuous engagement in R&D subsidization affects the success of investment effort and the firms’ decision to stop innovation projects.
