The purpose of this paper is to tackle the problem an electricity trader faces when trying to set and validate his sale prices.

The solution approach consists in offering adequate incentives to the customers in order to encourage them to shift their consumptions to more favorable time periods; this is achieved by suitable price modifications. The problem of determining the most sensible prices to offer yields to a quadratic programing model which can be efficiently solved to optimality.

This paper analyses an opportunity that traders can exploit for increasing their profit margins and, in general, for setting and validating their electricity sale prices. The real case of an Italian trader has been analysed and the numerical results show that the obtained sale price modifications may produce savings, both for the trader and for his customers.

This research provides insights about the problem an electricity trader faces when setting his sale prices; it mainly focuses on the Italian market although the developed mathematical model is sufficiently general to be adopted in different scenarios.

Resurgent interest in the life and work of the Italian Cambridge economist Piero Sraffa is leading to New Directions in Sraffa Scholarship. This chapter introduces readers to some of these developments. First and perhaps foremost is the fact that as of September 2016 Sraffa’s archival material has been uploaded onto the website of the Wren Library, Trinity College, Cambridge University, as digital colour images; this chapter introduces readers to the history of these events. This history provides sharp relief on the extant debates over the role of the archival material in leading to the final publication of Production of Commodities by Means of Commodities, and readers are provided a brief sketch of these matters. The varied nature of Sraffa scholarship is demonstrated by the different aspects of Sraffa’s intellectual legacy which are developed and discussed in the various entries of our Symposium. The conclusion is reached that we are on the cusp of an exciting phase change of tremendous potential in Sraffa scholarship.

This chapter provides a list and a brief description of files and documents where the name of Piero Sraffa is mentioned and are currently kept at the Archivio Centrale dello Stato and at the Archivio Storico Diplomatico. For each file or document we provide indication of the reference number where it is conserved and a transcription of one or two of the relevant documents out of more than 500 which have been located. The purpose of the chapter is to illustrate the results of archival research of the last decade, including more recent findings, and furnish a groundwork for further research, which may throw further light on documents already known to us, and lead to the discovery of new documents or information, so as to provide a better basis for the reconstruction of the biography of Piero Sraffa and of people whose lives entwined with his – Antonio Gramsci certainly ranking high among them.

This paper aims to analyse the roles of relational capital (RC) and knowledge management (KM) during the COVID-19 in Italian public and private hospitals, considering that intangible elements are essential during periods of uncertainty.

Authors used a qualitative design in a case study on two Italian hospitals that have different ownership structures, which are located in the epicentre of the pandemic in Lombardy. The study was carried out using the CAOS (“caratteristiche personali”, “ambiente”, “organizzazione” and “start-up”) model (Paoloni, 2021), which allows for comprehending and commenting on RC because of the connections between typical factors that influence an organisation. The model also allows for discussion of the use of a network and how it supports organisations.

Findings of the analysis showed that during the management of the COVID-19 health emergency, ownership structure was not a discriminating factor, the created relationships were similar and they were considered in the same way. The relationships were mainly formal (except for contributions by associations or individuals) and temporary. The RC's reactive role in overcoming crises was confirmed, and the findings indicated that this result was possible also, thanks to the KM's role played within the organisation.

Theoretical implications of the work are that it contributes to the sparse healthcare literature on intellectual capital (IC) and on RC and its relationships with KM. The practical implications are related to the creation of new relationships during the healthcare emergency between hospitals and the central government, which can be considered a useful lesson for the future. The theoretical implications derived from the analysis are generalisable to all organisations regardless of their type and location, as well as the practical implications are applicable to the entire national territory.
