Assessing the determinants of household electricity prices in the EU: a system-GMM panel data approach

Abstract

A meaningful portion of the consumer basket of European households and companies is embodied by electricity as well as gas or refined petroleum products. As energy products are essential inputs of nearly all final goods and services, whichever change of energy prices has a direct impact of the general price level. In this context, the main purpose of this study is to assess the main drivers of household electricity prices in the European Union (EU), throughout a period of deep sector transformation. Relying on Eurostat data, not only we analyze the long-term progress of household electricity prices across the EU, but also we provide empirical evidence on their determinants while confronting the results with the EU energy policy path. For this purpose a firsthand approach is herein developed based on a dynamic model with panel data through GMM proposal method by Blundell and Bond (1998) [4] with the Windermeijer (2005) [41] correction. The data analysis provides grounds for a relation between the variable of household electricity prices with variables related to sector liberalization, renewable energy sources which support the EU policy to boost liberalization. This study offers evidence that the sector liberalization is accompanied by a decreasing trend in prices, which is consistent with the European Commission's objectives to liberalize.

Estimating Factors Related to Fluoroquinolone Resistance Based on One Health Perspective: Static and Dynamic Panel Data Analyses From Europe

“…The dynamic models introduced a lagged variable as an explanatory variable and introduced instrumental variables by setting moment conditions to handle the autocorrelation of the dependent variables (Blundell and Bond, 1998), which could explore the possible endogeneity of the dependent variables (da Silva and Cerqueira, 2017). The dynamic model used for explaining AMR is shown in Equation (2):…”

Energy Efficiency in the Post-COVID-19 Era: Exploring the Determinants of Energy-Saving Intentions and Behaviors

“…Presently, research activities focusing on household energy consumption behavior may be classified into three broad categories, including (i) economic, (ii) technological, and (iii) psychological behavior-oriented perspectives (Arawomo, 2017;da Silva and Cerqueira, 2017;Zhou and Yang, 2016). However, several investigations have indicated that the impacts of these procedures are relatively scarce in reality (Wang et al, 2018a).…”

Electricity Markets during the Liberalization: The Case of a European Union Country

“…With the liberalization of the electricity market for households, the opening up of electricity prices to competition on the domestic electricity market was completed in Slovenia. The gradual liberalization has followed a similar path to some other EU and non-EU developed and emerging market economies [11,16,17,25,[38][39][40][41][42][43][44][45][46][47]87,97].…”

“…This has economic motives, given that closed national energy markets were incompatible with the concept of a single and competitive economic area. The main reason for sector deregulation was the desire to increase the efficiency of energy undertakings and the energy system as such, as well as to achieve the expected supply-side effects, i.e., lower electricity prices for final consumers [42,43]. The deregulation and liberalization of the electricity market contributed to unleashing entrepreneurial potential in the energy sector.…”
