Rise;rise;rise;remain unchanged.

Explanation:

The new classical theory also known as the neoclassical economic theory is one that repudiates and tends to restructure the John M. Keynes theory of macroeconomics, popularly referred to as the Keynesian Macroeconomics theory.

The new classical theory argues that efficient demand and supply is the most important feature or key behind the level of output, pricing, and consumption of goods and services by the people at a specific period of time in a country. Also, the new classical theory assumes that the wages of the employees in a country is flexible in contrast to the Keynesian macroeconomic theory.

Suppose that the government implements expansionary fiscal policy that raises aggregate demand, but the policy is unanticipated. According to new classical theory, in the short run the price level would rise and Real Gross Domestic Product (GDP) would rise. In the long run, new classical theory would predict that the price level would rise compared to its original long-run equilibrium level and that Real Gross Domestic Product (GDP) would remain unchanged.
