Demand describes the level of desire for goods and services among consumers in either specific markets or in the economy as a whole. Economic theory suggest demand ought usually to equal supply, because the suppliers themselves are earning wages which, in turn, drive demand. In fact, when demand flags for whatever reason, the economy is in danger of recession, while excess demand, outstripping supply, can create boom conditions that prove unsustainable. In the past, governments sought to manage the total level of demand in the economy, an approach that has partly returned to favour since the financial crisis.
