The article assesses single wholesale network (SWN) model - concentration of access to key infrastructure facilities within one company - for developing 5G. The main argument in favor of SWN is the possible capex savings, which are highly relevant in Russia. But setting up SWN will require state regulation which implies additional costs. The article shows limitations for SWN’s efficiency presenting quantitative analysis of the consequences associated with the SWN’s incentives to inflate capex, regulation inefficiency, guaranteeing non-discriminatory access as well as additional costs to comply with state procurement rules. The methodology may be used for regulatory impact assessment that make the article especially valuable in analysis of state intervention.

The paper investigates the mid-term results of the tariff regulation influence on the amount of capital expenditures in Russian electricity distribution sector. We estimate panel data with the dynamic investment model using system GMM method. We showed that horizon of tariff regulation period is statistically significant and transition from the short-term regulation to the long-term tariff system had positive effect on the amount of regulated companies’ investments. At the same time we found that the design of long-term regulation applied in Russia in 2009–2013 (type of RAB-regulation and long-term indexation) was not statistically significant to the amount of investments. All over all, the amount of investments in electricity distribution networks has similar to European peers explanatory factors. The obtained results are important to the further improvement of regulation in power energy and can be applied in district heating as well.
