In the first place, macro-economic research grounded on the Harvard economist Robert Barro’s endogenous technical change model13 has analysed the aggregate impact of broadband on economic development. In this case the guiding question is what is the contribution of broadband to GDP growth, productivity and employment? The second avenue has researched the impact of broadband from the microeconomic perspective. It is conducted at the firm level and emphasizes the contribution of broadband to business process efficiency and sales growth. The key issue here is to understand the return on broadband and IT investment at the firm and sector level. The third school of thought tackles this last question from a qualitative perspective, choosing the case study as its primary analytical tool.
