There is a probability that the firm can reset its price in any one period h (the hazard rate), or equivalently the probability (1-h) that the price will remain unchanged in that period (the survival rate). [13] Michael Parkin also put forward the idea. [33] The most important of these theories, new Keynesians was the efficiency wage theory used to explain long-term effects of previous unemployment, where short-term increases in unemployment become permanent and lead to higher levels of unemployment in the long-run.

Suppose that there are two unions in the economy, who take turns to choose wages. However, because prices are sticky in the New Keynesian model, an increase in the money supply (or equivalently, a decrease in the interest rate) does increase output and lower unemployment in the short run.
