Privatization Under Political Ties

open access: yesThe 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

open access: yesJournal 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

open access: yesJournal 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

open access: yesMathematical 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.

Robust Mean–Variance Portfolio Optimization: Mean–Variance–Variance Criterion Versus Mean–Variance–Standard Deviation Criterion

open access: yesMathematical 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 ...

Employee Fraud and the Statute of Limitations in a Search and Matching Model

open access: yesThe Manchester School, EarlyView.
ABSTRACT This paper integrates employee fraud into a Mortensen‐Pissarides search and matching model to analyze labor market dynamics under imperfect legal enforcement. We introduce a time‐dependent punishment structure where the offender's effective liability is governed by the statute of limitations. We characterize both short‐ and long‐run equilibria,

Firms' Payoffs in a Bertrand‐Edgeworth Game Under Triopoly

open access: yesMetroeconomica, EarlyView.
ABSTRACT This paper studies Bertrand‐Edgeworth competition among firms producing a homogeneous commodity under efficient rationing and constant (and identical across firms) marginal cost until full capacity utilization is reached. The focus is on the equilibrium payoffs under triopoly when the demand function is defined on the set of the non‐negative ...

A Formal Theory of Robert Nozick's Framework for Utopia

open access: yesNoûs, EarlyView.
ABSTRACT This paper offers the very first formal model of Robert Nozick's model of possible worlds and his vision of a utopian society, as outlined in Part III of Anarchy, State, and Utopia. Nozick envisioned utopia as a meta‐utopia—a collection of self‐organized, voluntary sub‐communities—arguing that such an institutional framework is equivalent to ...

Periodontitis and metabolic dysfunction‐associated steatotic liver disease

open access: yesPeriodontology 2000, EarlyView.
Abstract Objective Periodontitis is a chronic inflammatory disease with systemic effects that extend beyond the oral cavity and contribute to systemic immune and metabolic dysregulation. Chronic liver diseases, particularly metabolic dysfunction‐associated steatotic liver disease (MASLD) and its progressive phenotypes, have emerged as major global ...
