We find that the effect exists at the index level… Read more

Vol. 22, No. 2, 2024 by Ted Daverman, Joshua Kazdin, Michael Pensky and Fiona Sloof In this paper, we discuss the impact of extreme weather on US families with a specific focus on household finances. We first derive a life-cycle model of consumption, then introduce climate change-oriented consumption shocks as an additional expense which is… Read more

Vol. 22, No. 2, 2024 by Andrew Ang, Henry Shen, Jeff Shen and Rui Zhao We develop a model of optimal asset allocation with a market that has the potential to decouple. There are three Markov regimes: a regime where the market remains fully investable, a second regime where the market may become potentially decouple… Read more

As a result, it also incorporates the relative nature of investing—“Realativity”. Critical to investment practice, it provides… Read more

Vol. 21, No. 4, 2023 James X. Xiong, Thomas M. Idzorek and Roger G. Ibbotson U.S. active equity mutual funds have experienced net outflows since around 2006. The AUM-weighted performance remains similar over time, but equal-weighted performance (which emphasizes small AUM active funds) has deteriorated. Inflows/outflows contribute to the over/underperformance of individual active funds. We… Read more
