We analyze if two-part access tariffs solve the dynamic consistency problem Blazer Nike of the regulation of next generation networks. We model the industry as a duopoly, where a vertically integrated incumbent and a downstream entrant, that requires access to the incumbent's network, Acheter Nike Blazer Vintage Femme Basket Blazer Bebe compete on Hotelling's line. The incumbent can invest in the deployment of a next generation network that improves the quality of the retail services. We have three main results. First, we show that if the regulator can commit to a policy, a regulatory moratorium may emerge as socially optimal. Second, we show that if the regulator cannot commit to a policy, it can induce investment only when the investment cost is low. Third, we show that in this case, two-part tariffs involve very large payments from the entrant to the incumbent.
This paper reports the experiences of making Portland cement based corrugated roof sheets with the reinforcement of a Colombian natural fiber, named fique. The sheets were manufactured by a vacuum forming process. The raw material components of the sheets are given. The average flexural load to failure reported 2875 N/m at 14 curing days, which it is considered appropriate for a roofing sheet. Corrugated sheets produced with asbestos fibers using the same variables of processing reported 2400 N/m. Column permeability tests showed satisfactory results for the tried composites. The vacuum cylinder forming process for manufacture of corrugated sheets at the level of small scale production is promissory because is an environmental friendly low cost appropriate technology that does not need skilled labor.
