The estimation of the contribution of public capital will allow us to verify if the results are similar to those obtained for Canada and to shed light on the magnitude of the impact of productive infrastructure in this Canadian province. [...] In the subsequent section, we describe the methodology we used to estimate the coefficients and the following sections include a discussion of the results obtained and potential implications the provincial economy. [...] He concludes that the density of the capital stock of each region depending on the size of the area served by the capital stock is an important explanatory factor of regional disparities in terms of productivity of public capital.
