| Summary/Abstract |
The Italian electricity market was characterized by a remarkable decrease in demand during the COVID-19 lockdown (10 March to 2 June 2020). There were also negative peaks of over 50% and record low prices of about 20 Euro/MW. This paper aims to investigate the exercise of market power in the Italian power exchange during the pandemic, explicitly considering transmission line congestion, and disentangling the measure of the unilateral market power from congestion rent and re-dispatching costs.

| Summary/Abstract |
Reliable electricity is a key factor in improving the living conditions of households and sustainable development of countries. Developing country governments and international organizations address the question of how to obtain a reliable supply of electricity and thus eliminate power outages at the top of their political agendas. In this framework, the aim of this paper is to estimate the willingness to pay of Indian urban consumers for having a continuous supply of electricity, avoiding unexpected power outages, using contingent valuation method. Two different econometric approaches are used. The households in the survey have been asked to state their willingness to pay for five different types of outages. Empirical data from 1043 Indian households has been analyzed using double hurdle approach. The econometric results indicate that, among the investigated households with an average individual annual income around $1630,00, their willingness to pay to avoid power outage strictly depend on the length of outages ranging, on average, from $0.37 (2 h) $3.00 (12 h), that is, households prefer to reduce the duration of outages. Further, income and environmental attitude of respondents positively influence higher WTP to avoid power outages. Our findings provide useful insights for policy makers to design and promote more reliable and customer centric energy generation and distribution models.

| Summary/Abstract |
Environmental and technical efficiency in the electricity sector is a major focus of regulatory policies aimed at hastening greenhouse gas reduction and lowering energy prices for final consumers. Understanding the impact of market and environmental regulations on efficiency is crucial for the design and choice of policy packages. At the national level, the productivity response to regulations depends on unobserved country-specific factors that current empirical analyses have not modelled. In this framework, we analyse the regulation effects on efficiency in the electricity sector for a panel of European Union countries. We explicitly consider the effects of the environmental regulation along with the market regulation. Our estimation strategy uses the Bayesian shrinkage estimator, which can deal with the bias aggregation problem and cross-country heterogeneity. It allows us to identify the different transmission channels through which regulatory policy is implemented. The results highlight divergent behaviours at the country level. The direct impacts of the market and environmental regulatory policies on productivity are negative—around −2.7% and −2.3%, respectively—but the countries vary in the degree to which they are able to compensate these negative effects.

| Summary/Abstract |
In this paper, we derive optimal zonal prices in the Italian day-ahead electricity market using estimation of a complete system of hourly demand in 2010–2011. In Italy, the hourly equilibrium price for all buyers is computed as a uniform average of supply zonal prices, resulting from market splitting due to line congestion. We model ex-ante individual bids expressed by heterogeneous consumers, which are distinguished by geographical zones. Using empirical estimations, we compute demand elasticity values and new zonal prices, according to a Ramsey optimal scheme. This is a new approach in the wholesale electricity market literature, as previous studies have discussed the relative merit of zonal prices, considering only the issue of line congestion. Our results show that the optimal pricing scheme can improve welfare in the day-ahead Italian electricity market, with respect to both the existing uniform price scheme and the proposal to charge the existing supply zonal prices to the demand side.
