Edgeworth Price Cycle
An Edgeworth price cycle is cyclical pattern in prices characterized by an initial jump, which is then followed by a slower decline back towards the initial level. The term was introduced by Maskin and Tirole (1988) in a theoretical setting featuring two firms bidding sequentially and where the winner captures the full market. Phases of a price cycle A price cycle has the following phases: * War of attrition: When the price is at marginal cost, the firms are engaged in a war of attrition where each firm hopes that the competitor will raise her price first ("relent"). * Jump: When one firm relents, the other firm will then in the next period undercut, which is when the market price jumps. This first period is the most valuable to be the low-price firm, which is what causes firms to want to stay in the war of attrition to force the competitor to jump first. * Undercutting: then follows a sequence where the firms take turns at undercutting each other until the market arrives back ...

Sticky Pricing
Nominal rigidity, also known as price-stickiness or wage-stickiness, is a situation in which a nominal price is resistant to change. Complete nominal rigidity occurs when a price is fixed in nominal terms for a relevant period of time. For example, the price of a particular good might be fixed at $10 per unit for a year. Partial nominal rigidity occurs when a price may vary in nominal terms, but not as much as it would if perfectly flexible. For example, in a regulated market there might be limits to how much a price can change in a given year. If one looks at the whole economy, some prices might be very flexible and others rigid. This will lead to the aggregate price level (which we can think of as an average of the individual prices) becoming "sluggish" or "sticky" in the sense that it does not respond to macroeconomic shocks as much as it would if all prices were flexible. The same idea can apply to nominal wages. The presence of nominal rigidity is an important part of mac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
