Price stickiness or sticky prices or price rigidity refers to a situation where the price of a good does not change immediately or readily to the new market-clearing price when there are shifts in the demand and supply curve. Here's how that story would play out: When all the worker's wages are lowered, their income goes down. In both (a) and (b), demand shifts left from D 0 to D 1. If sticky prices were simply a choice made by some firms that had little economic consequence, the stock market returns would not behave so differently for the different groups of firms.

Sciences, Culinary Arts and Personal How does the distinction between flexible and sticky prices impact the study of macroeconomics? If all prices, including wages, are flexible, then every market is in equilibrium all the time, because prices adjust instantaneously to make it so.

These models treat the price level as \sticky" in the short run. Now, let's talk about prices and how they adjust to changing conditions. Price Stickiness is the resistance of a price (or set of prices) to change, despite changes in the broad economy that suggest a different price is optimal. The sticky price theory states that the short-run aggregate supply curve slopes upward because the prices of some goods and services are slow to adjust to changes in the overall price level. In other words, some prices tend to resist change despite economic forces that would typically push the price up or down.The affect of sticky prices can be seen in product prices, salaries and asset prices.
