New Classical

New classical economics builds on neoclassical ideas and strives to explain how fluctuations in employment and real wages are caused by technological changes and by willingness to work. A distinguishing theory of new classical economics is that wages and prices are immediate and flexible. When the marginal product of labour is affected by technological changes, it will lead to changes in the demand for labour. This will lead to shifts in employment level and wages¹. Changes in willingness to work will cause changes in the labour supply and therefore shifts in the level of employment and wages.

New classical economists will assume that, in business cycles, short-run fluctuations in real GDP are the result of fluctuations in potential output. Therefore, unemployment is equal to the non-accelerating inflation rate of unemployment (NAIRU) and it is the NAIRU that fluctuates¹. Fluctuations in cyclical unemployment are caused by supply shocks from sources like oil price changes and changes in taste.

New classical theory assumes that labour markets are always clear. When people are not working, they are assumed to have voluntarily withdrawn from the labour market. This means that there is no involuntary unemployment.

New classical theory has been supported by the claims that an economy affected by technological shocks and changes in taste shows similar fluctuations to those of a real economy¹. The ideas also show how shocks can spread to different sectors of the economy over time.

Invisible Hand Theory

The invisible hand theory which essentially says, people by pursuing their own economic self interest, help allocate resources in the economy as if an "invisible hand" is at work to do so. How would you say this theory manifests itself in the hands-off approach of the classical economists with respect to government intervention

Beethoven recordings or classical music recordings in general c. Subway rides during the next 6 months or subway rides during the next 5 years d. Root beer or water

Classical AS Curves

10. Say all economies of the world possess classical AS curves. In such a world, we would predict: A. Higher levels of imports by country 1 that would raise the price level in country 2, but not impact domestic output B. Interest rates would be dependent on activities in the AS market C. Higher levels of exports by country


On W Beach, there are two hotels, Wd and B. The practice of guaranteed price matching is illegal. If the two firms act independently (they do not engage in price fixing or any other collusive behavior), each firm will rent 50 rooms per day at a price of $50 per room and an average cost of $45 per room. Under a price-fixing or
