“…Other empirical studies have focused on consumer satisfaction Florio, 2011), aggregate output (e.g., Copenhagen Economics, 2005;Zhang et al, 2008;Prati et al, 2013), productivity (e.g., Zhang et al, 2005;Pompei, 2013;Borghi et al, 2016;Polemis, 2016;Polemis and Stengos, 2017;Gugler et al 2017), quality of service (Nardi, 2012), aggregate network losses (Nagayama, 2010), greenhouse gas emissions (Asane-Otoo, 2016; Clò et al, 2016), and investments within the electricity sector (e.g., Alesina et al, 2005;Cambini and Rondi, 2010;Nardi, 2012;Gugler et al, 2013;Sugimoto, 2019Sugimoto, , 2021. As this study investigates the effect of structural reforms on network performance using different performance indicators (network investments, reliability and losses), we are mainly interested in the previous empirical studies using similar performance indicators, including Alesina et al (2005), Nagayama (2010), Cambini and Rondi (2010), Nardi (2012), Gugler et al (2013) and Sugimoto (2019Sugimoto ( , 2021. Alesina et al (2005) find a positive impact of structural reforms, in particular entry liberalization, on gross investments in several network industries in 21 OECD countries in the period 1975 to 1998.…”

“…Empirical studies on the effect of regulatory reforms on the electricity industry have considered a wide range of outcome variables, including consumer prices (e.g., Steiner, 2001;Hattori and Tsutsui, 2004;Nagayama, 2007Nagayama, , 2009Florio et al, 2007;Erdogdu, 2011;Fiorio and Florio, 2013;Bacchiocchi et al, 2015;Hyland, 2016), consumer satisfaction Florio, 2011), aggregate output (e.g., Copenhagen Economics, 2005;Zhang et al, 2008;Prati et al, 2013), productivity (e.g., Pompei, 2013;Borghi et al, 2016;Polemis, 2016;Polemis and Stengos, 2017;Gugler et al 2017), transmission and distribution losses (Nagayama, 2010), investment (e.g., Alesina et al, 2005;Cambini and Rondi, 2010;Nardi, 2012;Gugler et al, 2013;Sugimoto, 2019Sugimoto, , 2021 and greenhouse gas emissions (Asane-Otoo, 2016;Clò et al, 2016).…”

“…In contrast, the ITO model allows for some degree of vertical integration, being a more strongly regulated form of legal unbundling (LU) in which the parent company is allowed to own some or all shares of both transmission and commercial activities. Under the ITO model, it is not evident that the operator only pursues its' own profits, as it may also consider upstream profits (Sugimoto, 2021). Another important difference between OU over the ITO model is that OU may result in the loss of vertical coordination synergies between generation and transmission segments (e.g., Brunekreeft, 2008;Brunekreeft, 2015;Gugler et al, 2017;Meyer, 2012).…”

First, I want to thank my colleague Peter Perey. Our discussions on all sorts of research and energy-related topics in the office and during lunch and coffee breaks have contributed to completing this research. Being able to pass by and walk into your office at almost any time and to draw out new ideas on the whiteboard was very helpful. In addition, I owe thanks to Daan Hulshof for his valuable lessons and contributions as a supervisor and co-author to one of my chapters. You helped me to formulate and write down research ideas more precisely, which has improved the quality of my chapters. Moreover, I thank Floris van Montfoort for being a great office mate and travel companion. I enjoyed our visits to the IAEE European Conferences in Athens (2022) and Milan (2023), discussions on all sorts of things, playing padel and cycling home from work. Also, I want to thank Arjen Veenstra for baking formidable pies and cakes, most notably his Oranjekoek and Skyr cheesecakes, and bringing them to the office. Apart from enjoying your baking expertise, I enjoyed the occasional distractions and your presence as an office mate in the last few months of my PhD.Finally, I owe gratitude to my family members and friends for their loving support. In particular, I thank my parents who gave me the freedom to choose my own path in life and taught me to persevere in whatever I would choose to pursue. I also thank my grandma Anni for inviting me for dinner almost every week and her supportive role in all kinds of things. At last, I thank my friends Bauke, Harm-Jan, Diederick, Douwe, Jelle, Maikel, Wouter, Mats and Robin for being a great source of energy and for celebrating achievements.
