On the existence of pure strategy equilibria in large generalized games with atomic players [PDF]
We consider a game with a continuum of players where only a finite number of them are atomic. Objective functions and admissible strategies may depend on the actions chosen by atomic players and on aggregate information about the actions chosen by non ...

Privatization Under Political Ties
The Journal of Industrial Economics, EarlyView.ABSTRACT I study a product differentiation model with endogenous entry where a politically connected public firm competes with a private one. Consumers are heterogeneous in their willingness to pay. I argue that—because of political ties—the public firm may mimic the preferences of the consumer with the median willingness to pay.

Welfare implications of fair and accountable insurance pricing
Journal of Risk and Insurance, EarlyView.Abstract This paper introduces an empirical framework to evaluate the welfare implications of fair and accountable insurance pricing by modeling the complete pricing process, including demand and price optimization. Moving beyond traditional cost modeling, we analyze both discrimination‐related fairness criteria and broader regulatory constraints, such

Contingent capital: A tale of two valuations
Journal of Risk and Insurance, EarlyView.Abstract This study investigates the valuation gap between buyers and sellers of insurers' contingent capital, driven by asymmetric exposures to tax benefits, capital injections, and bankruptcy costs. We develop a novel Twin‐Tree Model with Jumps (TTMJ) that models the insurer's asset value dynamics by incorporating catastrophe risk, insolvency risk ...

Relative Arbitrage Opportunities With Interactions Among N Investors
Mathematical Finance, EarlyView.ABSTRACT The relative arbitrage portfolio outperforms a benchmark portfolio over a given time‐horizon with probability one. With market price of risk processes depending on the market portfolio and investors, this paper analyzes the multi‐agent optimization of relative arbitrage opportunities in the coupled system of market and wealth dynamics.

Mathematical Finance, EarlyView.ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...
