In this paper we analyse the short-term spot price of European Union Allowances (EUAs), which is of particular importance in the transition of energy markets and for the development of new risk management strategies. We use daily spot market data from the second trading period of the EU ETS. Emphasis is given to short-term forecasting of prices and volatility. Due to the characteristics of the price process, such as volatility modelling, breaks in the volatility process and heavy-tailed distributions, we investigate the use of Markov switching GARCH (MS-GARCH) models. We find that these models distinguish well between states, and that the volatility processes in the states are clearly different. Our findings support the use of MS-GARCH models for risk management, especially because their forecasting ability is better than other Markov switching or simple GARCH models.

Purpose
This paper aims to examine the discursive constitution of leadership identities by senior women leaders working in the City of London. This study draws on postfeminism as a critical concept to explore this constitution, as it has produced the cultural conditions for the reconfiguration of masculine and feminine gender norms in leadership.


Design/methodology/approach
In a qualitative study, 13 women leaders in positions of power in the City of London were interviewed. Discourse analysis techniques were used to unpack the postfeminist shaping of leadership identities


Findings
At the heart of the leadership identities that senior women leaders construct is a gendered hybridity that is a multifaceted calibration of masculine and feminine attributes and behaviours. Postfeminist discourses of individualism, choice and self-improvement are entangled with discourses of authenticity, relatability and connectivity as particular leadership assets. The gendered hybridity of leadership identities unfolds the possibility for a fundamental makeover of leadership by opening-up space for a transformative change that accommodates women leaders.


Originality/value
To the best of the authors' knowledge, this study is among the very few studies that foreground the leadership identities that women leaders construct within the confines of postfeminist gender regimes. It shows how these women invoke authenticity, unfolding possibilities for the transformational change of and political challenge to traditional gendered leadership in their organizations.
