Title: Appropriability mechanisms, innovation and productivity:
	 Evidence from the UK
Abstract: We use an extended version of the well-established Crepon, Duguet
	 and Mairesse model (1998) to model the relationship between
	 appropriability mechanisms, innovation and firm-level productivity.
	 We enrich this model in several ways. First, we consider different types
	 of innovation spending and study the differences in estimates when
	 innovation spending (rather than R&D spending) is used to predict
	 innovation in the CDM model. Second, we assume that a firm
	 simultaneously innovates and chooses among different appropriability
	 methods (formal or informal) to protect the innovation. Finally, in the
	 third stage, we estimate the impact of the innovation output conditional
	 on the choice of appropriability mechanisms on firm's productivity.
