Zhiqun Li. The Impact of Windfall on Marital Happiness: A Theoretical and Empirical Analysis

Key Findings: This study theoretically analyzes how windfalls affect marital happiness based on reference-dependent framework and empirically validates the theoretical results. The main finding is that windfalls can significantly increase marital happiness for married individuals through consumption, leisure time, perception of current life, and prospects for future life. The increase in marital happiness exhibits a positive spillover effect on the mental health of family members.

Zhiqun Li. Online and Offline Retailing: Mutual Benefit or Prisoner’s Dilemma?

Key Findings: This study investigates retailer’s channel decision under dual consumer heterogeneity. The first retailer to adopt an online channel gains a relative advantage in market share and pricing, but intensified competition reduces its absolute profit below the offline benchmark. This advantage encourages imitation, creating a prisoner’s dilemma in which dual-channel competition eliminates offline market power and drives both retailers’ profits to zero. Although this outcome harms retailers, it substantially increases consumer surplus and overall social welfare.
