We include initial holdings in the jungle economy of Piccione and Rubinstein (Economic Journal, 2007) in which the unique equilibrium satisfies lexicographic welfare maximization. When we relax assumptions on consumption sets and preferences slightly, equilibria other than lexicographic welfare...

We include initial holdings in the jungle economy of Piccione and Rubinstein (Economic Journal, 2007) and relax the assumptions on consumption sets and preferences. We show that initial holdings are irrelevant for lexicographic welfare maximization. Equilibria other than such maximizers can be...

Of the two most widely estimated univariate asymmetric conditional volatility models, the exponential GARCH (or EGARCH) specification can capture asymmetry, which refers to the different effects on conditional volatility of positive and negative effects of equal magnitude, and leverage, which...
