The AD-AS model explains how full employment can be reached from a situation of deep recession, assuming no fiscal policy stimulus.

The model therefore assumes a pre-globalization world where increases in aggregate supply on the part of companies in the U.S. will actually be made by U.S. workers. The thesis statement for this paper is that technological innovation is the most likely means by which the economy can return to full employment under the circumstances described.

Businesses are likely to begin this recession with excess capacity, keeping them from making investments as well. However, the economy will still be functioning -- it will only be below its capacity level.
Over time, technological improvements will increase the aggregate supply. This can occur either through major new technological innovation -- the development of the Internet is cited -- that shifts the AS curve to the right quickly. Or, these changes can occur gradually, which seems to be the case most of the time, with incremental improvements in technology and efficiency increasing productivity and stimulating new consumer demand. Such improvements will encourage business investment as well, either because projects are more profitable, or because new products are spurring new demand. An example of the latter would be the smartphone business, which emerged in the depths of the recession but did not lack for demand.
