“…3 See, among others, Thaler (1990, 1991), Ahmed, Koppl, Rosser, and White (1997), Gemmill and Thomas (2002), Hughen and Wohar (2006), and Berk and Stanton (2007) who have shed light on the factors and mechanisms that contribute to the observed discounts and premiums in CEFs. 4 Many researchers put forward theoretical hypotheses for such puzzling phenomena of the CEF Puzzle, such as investor sentiment (De Long, Shleifer, Summers, and Waldmann, 1990;Lee et al, 1991;Chopra, Lee, Shleifer, and Thaler, 1993;Anderson, Beard, Kim, and Stern, 2013); arbitrage costs (Pontiff, 1996;Gemmill and Thomas, 2002); accumulated tax liability effects (Malkiel, 1995;Day, Li, and Xu, 2011); the structure of management fees and compensation (Ross, 2002;Berk and Stanton, 2007); and asset price bubbles (Jarrow and Protter, 2019). These theoretical hypotheses represent different perspectives on the underlying drivers of the CEF puzzle, aiming to provide a comprehensive understanding of this intriguing phenomenon.…”
