Stabilizing energy markets: A dynamic analysis of price cap regulation in oligopolistic environments

Abstract
This paper provides a theoretical analysis of Cournot oligopoly dynamics under price cap regulation, particularly in the context of exogenous shocks, akin to recent events in the energy markets. Utilizing the 0–1 chaos test, we identified significant shifts in market behavior, highlighting the sensitivity of oligopolistic energy markets to regulatory parameters. Our findings indicate that improperly set tax policies can lead to chaotic and unstable market conditions. Exogenous shocks can cause firm divergence, which can be mitigated by introducing a short-term price cap. The analysis demonstrates that price caps effectively moderate the impact of exogenous shocks, enabling firms to revert to their pre-shock state without altering market dynamics. Moreover, the results suggest that price caps are more effective than windfall taxes. This research underscores the necessity for precise and adaptive regulatory frameworks to maintain market stability and protect both consumers and businesses from extreme price fluctuations. These insights are vital for policymakers aiming to design interventions that balance market stability with consumer protection in an increasingly interconnected and volatile global economy.
Is there really a dictator's dilemma? Information and repression in autocracy

Abstract
AbstractIn his seminal work on the political economy of dictatorship, Ronald Win-trobe posited the existence of a “dictator’s dilemma,” in which repressionleaves an autocrat less secure by reducing information about discontent. Weexplore the nature and resolution of this dilemma with a formalization thatbuilds on recent work in the political economy of nondemocracy. When theregime is sufficiently repressive, and the dictator’s popularity correspondinglyunclear to opposition as well as autocrat, the ruler faces two unattractiveoptions: He can mobilize the repressive apparatus, even though there may beno threat to his rule, or he can refrain from mobilizing, even though the dan-ger may be real. Semicompetitive elections can ease the dilemma through thecontrolled revelation of discontent. Paradoxically, the manipulation of infor-mation through such non-repressive means can allow for more rather thanless repression.
Maternal religiosity and social support to mothers: helpers’ religious identity matters

Abstract
Research demonstrates that religious people are trusted more, receive and provide more cooperation, and have larger cooperative networks. This line of research also suggests, that religious prosociality is not always parochial, and often extends to people outside of a religious ingroup. Here, we test whether the intensity of religious practice associates with received support from coreligionists and/or non-coreligionists among a sample of American mothers. Specifically, we test the association between self-reported behavioral religiosity of religious (here Christian) and non-religious mothers from the Greater Pittsburgh area, USA, and the frequency of emotional support (Nmothers = 517, Nsupporters = 1999) and housework help (Nmothers = 447, Nsupporters = 997) they received from Christian and non-religious supporters. We found that maternal religiosity was positively associated with the frequency of housework help received from Christian supporters, but not from non-religious supporters. We did not find evidence for an association between maternal religiosity and emotional support received from religious nor non-religious supporters. We interpret our results through the lens of religious signaling theory.
