Return and Volatility Properties Comparison of High-ESG Rating and Low-ESG Rating Exchange-traded Funds (ETFs)
by John Francis T. Diaz , Michael N. Young  and  Yogi Tri Prasetyo
Abstract
This study compares return and volatility performance of exchange-traded funds (ETFs) with high-ESG (Environment, Social, and Governance) rating vs. low-ESG rating.

Bayesian-Nash equilibria for fuzzy value auctions
by Alexey S. Shvedov
Abstract
This paper analyses a model of private value auctions with symmetric risk-neutral bidders, where bidders' private values of an indivisible good are fuzzy. The auction is studied as a game with incomplete information. Fuzzy random variables, their quantile functions, and expressions for expectations through quantile functions are used. An explicit expression for the solution is [...] Read more
