What type of cartel conduct involves agreeing on fixed prices among agents?

The type of cartel conduct that involves agreeing on fixed prices among agents is price fixing. Price fixing occurs when competing businesses make agreements to set prices at a certain level instead of allowing market forces to establish them. This practice can lead to artificially inflated prices for consumers and reduces competition in the marketplace. In a price-fixing scenario, firms collude to maintain prices, which can manipulate supply and demand dynamics, harming both consumers and the overall economy.

Market sharing refers to agreements where competitors divide up markets or territories, which does not specifically pertain to price agreements. Bid rigging involves conspiring to manipulate the outcome of bidding processes, ensuring certain parties win contracts at inflated prices. Output restrictions involve agreements to limit production levels to drive up prices, but again, this does not focus on setting fixed prices directly. Thus, price fixing uniquely captures the essence of the behavior defined in the question.
