"The objective of this thesis is to make a theoretical and empirical contribution, decoding the nature of productivity disparities across different economic actors, and providing reflections for policy advice. One of the main hypothesis is that efficiency-originated productivity gains vary largely among different economic units, as the degree of the economic impact will surely depend significantly on some characteristics of the agents under analysis (firms or regional economies). With a manifest purpose of making contributions which can enrich advice in public-policies, this thesis will focus particularly in most-disadvantaged economic units, intending to find out which circumstances can help them to converge to the most productive ones. In the first place, we present a model which incorporates capital accumulation and spatial spillovers across economies, while allowing for regional differences in absorptive capacity. This model is estimated using a sample of EU regions, over a period including the enlargement of the single-market area in the mid-2000́s. Results confirm the relevance of local absorptive capacity, that is directly linked with the process of making the most of externalities. Capital deepening reduced the role of capital in explaining the regional productivity gap, but was not enough to help lagging regions to equal the return to human capital investments reached by most advanced regions. In the second place, we analyze the incidence of broadband on regional productivity in Brazil, intending to find out if the economic impact is uniform across all territories of the country. The possibility of performing a regional approach, instead of the usual country-level analysis, means an opportunity to disentangle the economic impact of broadband at territories which share a common institutional and regulatory framework as are the regions inside a country. Results suggest that the impact of broadband on productivity is positive although not uniform across regions. On the one hand, it seems to depend on connection quality and network effects. Faster download speed and critical-mass accounting for network externalities in the region enhance the economic impact of broadband. On the other hand, higher productivity gains are estimated for the less developed regions. The fact that the less productive regions in Brazil seem to be benefiting more from broadband may suggest that it can constitute a factor favoring regional convergence in the country. Finally, we test three hypotheses regarding the link between internet and firm productivity: i) internet adoption and use constitute a source of productivity growth for firms in Latin America, ii) the intensity of its use also matters, and iii) the link between the new technologies and productivity levels is not uniform over the whole productivity distribution. The evidence found fills the gap of scarce and fragmented literature focused on Latin America, and is aligned with previous research for more developed regions which has generally recognized that Information and Communication Technologies have radically changed how modern business are conducted, benefitting firm performances through several channels, such as increasing the efficiency of internal processes, expanding market reach or increasing innovation. The findings suggest that low and medium productive firms benefit more from an expansion in internet adoption and use, in comparison with the most productive ones. If this evidence is supposed to reflect long-term effects, then public policies oriented to massify internet adoption and promote internet use intensively will surely contribute to reduce inequalities of enterprise's productivity levels, promoting a level playing field among Latin American firms, something especially relevant for the most unequal region of the world." -- TDX.
