Optimal policies for electromobility: Joint assessment of transport and electricity distribution costs in Norway

The objective of this work is to detect what problems of inefficiency electricity distribution companies have, in order to disseminate this information and to allow distributors and public agencies to be more precise in calculating their costs. In turn, this will have an indirect impact on the price of the kilowatt in order to try to reduce its volatility. It should be noted that the volatility of the kilowatt price is mainly due to distribution costs and more specifically to access tolls. In the present paper, knowing that the distribution activity is a regulated activity, the efficiency in the electricity distribution companies will be studied. To this end, a study has been carried out on the efficiency of the main electricity distribution companies in Spain (Endesa, Iberdola, Union Fenosa, EDP and Viesgo) during the period of 2006–2015. The technique used was the Multi-period efficiency measurement in Data Envelopment Analysis, an input-oriented model at constant scales, working with panel data. The conclusions in this paper indicate that Spanish electricity distribution companies could improve their levels of efficiency if they improve the use of some inputs. This analysis demonstrates that overcapacity and deficit tariff have a negative influence on the efficiency level. Finally, this paper is useful as it shows that regulation again plays an essential role in regulated activities, requiring a commitment on the part of the State in order to improve efficiency in regulated activities.

Why have many transition economies succeeded by pursuing policies which are so different from the radical economic liberalization (shock therapy) that is normally credited for the economic success of countries of Central Europe? First, optimal policies are context dependent, they are specific for each stage of development and what worked in Slovenia cannot be expected to work in Mongolia. Second, even for the countries with the same level of development reforms that are necessary to stimulate growth are different; they depend on the previous history and on the path chosen. The reduction of government expenditure as a share of GDP did not undermine significantly the institutional capacity of the state in China, but in Russia and other CIS countries it turned out to be ruinous. The art of the policymaker is to create markets without causing government failure, as happened in many CIS countries.

Increasing material, processing, and distribution costs have raised superphosphate prices to a point where many farms cannot support the costs of meeting maintenance phosphate requires men& Alternatives to superphosphate, particularly those that have lower processing costs and contain more P, may offer a solution to the problem provided they are agronomically as effective. Phosphate rock may indeed be such an alternative. Preliminary results from a series of five trials in Northland show that on soils of moderate P fertility, with low phosphate retention (PR) and high pH (5.9.6.0), initial pasture growth responses to rock phosphates are smaller than those from single or triple superphosphate. On one soil of higher PR and lower pH, the differences in yield between the rock-phosphates and the super. phosphates were smaller. Of the rock phosphates tested, Sechura and North Carolina (unground and ungranulated) tended to be more effective than ground and granulated Chatham Rise phosphorite. The effect on production of applying fertilisers once every three years, as opposed to annual applications is being investigated using triple superphosphate and Sechura phosphate rock. After two years, production levels appear largely unaffected by differences in application frequency. A comparison of locally-produced superphosphate with a reference standard showed that both performed similarly, indicating that the local product was of satisfactory quality.
