COOPERATIVE ANTITRUST MONOPOLIZATION AND THE THEORY OF CONTESTABLE MARKETS [PDF]

The judiciary has relied on a firm's market share to evaluate the presence of monopoly power for a Sherman Act monopolization violation. However, an allegation that a firm's market share constitutes monopoly power may be refuted by evidence that there ...

Policy Effectiveness in Managing Drug Shortages: Evidence From South Korea (2015–2024)

World Medical &Health Policy, EarlyView.
ABSTRACT Drug shortages represent a growing policy challenge for healthcare systems worldwide. This study investigates actual drug shortage events in South Korea from 2015 to 2024, using a “Shortage Occurred vs. Shortage Non‐Occurred” framework to distinguish real‐world disruptions from administrative classifications.

THE POWER’S MECHANISM OF A MONOPOLY IN A MARKET ECONOMY Antoniu Predescu, Spiru Haret University Iuliana Predescu, Romanian- American University Bucharesti Stela Aurelia Toader, Romanian- American University Bucharest Mihai Aristotel Ungureanu , Romanian- American University Bucharest [PDF]

Monopolies make their presence felt in a market economy, not necessarilythrough 100% ownership control of a market, nor less, because there is a law thatsanction its existence; in most cases, the existence of a monopoly and hence its corollary,i.e ...

Effect of Carcass Feeds on Feeding Behavior and Social Interactions in Zoo‐Based African Wild Dogs (Lycaon pictus)

Zoo Biology, EarlyView.
Feeding carcasses to African wild dogs stimulates more natural feeding patterns and social interactions than feeding with individual pieces or butchered carcasses. Image credit: Jordan Michelmore. ABSTRACT Management of African wild dogs (Lycaon pictus) in zoos involves several challenges, including the difficulty of providing appropriate stimulation ...

The role of developmental plasticity in eco‐phenotypic population dynamics

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Individual variation in development can strongly impact population density via its impact on demography. When this variation in development is caused by developmental plasticity, the resulting effects on population density are characterised as ‘eco‐phenotypic dynamics ...

Monopoly rights: a barrier to riches [PDF]

Our thesis is that poor countries are poor because they employee arrangements for which the equilibrium outcomes are characterized by inferior technologies being used, and being used inefficiently.

The role of insularity: Plants have few ornithophilous traits but are visited by morphologically more distinct hummingbirds in the Caribbean islands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits determine interactions between plants and pollinators, and to increase pollination efficiency, many plants have evolved traits to attract specific pollinator groups. However, biogeographical setting may influence trait evolution and biotic interactions.

Informational Structure and Effciency in Monopoly [PDF]

The paper focuses on efficiency under monopoly. Contrary to common wisdom, nine examples given in the paper show that a Pareto-efficient output in monopoly is possible under both linear and nonlinear pricing.

Environment‐driven plasticity in foraging behaviour: From individual‐level processes to community‐level consequences

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plasticity describes the ability of a genotype to adaptively produce different phenotypes in response to environmental cues. Even though the concept of phenotypic plasticity was originally conceived for morphological characters, environmentally cued modification of ...
