We empirically investigate the effect of RES generation on the Italian spot and regulation prices by examining price dynamics from 2012 to 2014 in day-ahead, intra-daily and balancing market sessions. We model the relationships among spot, adjustment and regulation prices and provide empirical evidence that the intra-daily sessions are well-functioning and low-cost market tools to ease the introduction of a high share of RES.

We show that the electricity–fuel nexus found over 2006–2008 changed dramatically over 2010–2014 for the majority of countries considered. In particular, the long-run dependence of electricity from gas and coal prices is much lower in recent years. Furthermore, our results confirm that the considered EU countries are becoming less integrated as RES-E increases.

We analyse vertical integration between generators and retailers in electricitymarkets and we discuss the implications for price decisions of the presence of a symmetric (cost) information in a simple P-A framework. We analyze a situationin which generators post supply bids taking into account the profit of the entire vertically integrated group they belong to. We then discuss the way in which the degree of vertical integration affects this bidding strategy.

We investigate how the design of compensation systems influences workers’ behaviours at the organizational level by building upon the consequences of equity theory at the individual level.

We investigate whether financial markets reacted to the regulatory changes implied by the publication of the list of systemically important financial institutions (SIFI) and the new rules designed to address the too-big-to-fail problem of systemic banks.

Empirical research on the validity of the purchasing power parity (PPP) condition is generally based on real exchange rates built using the consumer price index (CPI), but fails to provide clear support to PPP. In this paper we show theoretically that, even if the law of one price (LOP) holds for traded goods, CPI-based real exchange rates are not mean-reverting, and are neither stationary nor integrated. Our theoretical results are validated both by simulations and an empirical application.

In this article we show that these market conditions may imply the non-concavity in prices of the pivotal supply function, which in turn means that there can be situations in which a pivotal operator's supply has virtually no price limits. We also show that this monopolistic market power can be significantly reduced by vertical integration and/or regulatory policies such as virtual power plants. We examine the existing price-cap and propose an alternative mechanism.

We propose a rank-test of the null hypothesis of short memory stationarity possibly after linear detrending. For the level-stationarity hypothesis, the test statistic we propose is a modified version of the popular KPSS statistic, in which ranks substitute the original observations.

In this paper we apply a model of optimal bidding behaviour to the Italian wholesale electricity market under three hypotheses: i) costs of generation are private knowledge, ii) firms can be vertically integrated, and iii) firms can sell part of their production in advance with bilateral contracts. We first use optimal bid functions and market data to retrieve time-varying marginal cost functions, price-cost margins and Lerner Indexes of market power for a sample of Italian companies.

The aim of the paper is to show evidence of possible inconsistencies of PLS-PM as a statistical tool to estimate structural equation models with formative-reflective schemes. We pursue this goal, discussing a real-data example where PLS-PM fails to identify existing causal links between the variables concerned. We also suggest a possible formal interpretation of this fact, focusing on the way PLS-PM represents the link between reflective latent variables and their indicators.
