Demand and supply interdependence – stimulus wins, austerity fails
My Phd research, was in part, exposing the myths in conventional or mainstream economics arguments that claim that structural imbalances in the labour market arise independently of the economic cycle and hence, aggregate spending. The mainstream used this assertion to draw the conclusion that government policy could little to bring unemployment down when mass unemployment was largely ‘structural’ in nature. Instead, they proposed that supply-side remedies were necesary, which included labour market deregulation (abandoning employment protection etc), minimum wage and income support cuts, and eroding the influence of trade unions. At the time, the econometric work I undertook showed that so-called structural imbalances were highly sensitive to the economic cycle – that is, the supply-side of the economy was not independent of the demand-side (the independence being an article of faith of mainstream analysis) and that supply imbalances (for example, skill mismatches) rather quickly disappeared when the economy operated at higher pressure. In other words, government fiscal policy was an effective way of not only reducing unemployment to some irreducible minimum but, in doing so, it increased the effectiveness of the labour force (via skill upgrading, higher participation rates etc) – that is, cleared away the so-called structural imbalances. A relatively recent paper from researchers at the Federal Reserve Board in Washington – Aggregate Supply in the United States: Recent Developments and Implications for the Conduct of Monetary Policy – finds new US evidence to support the supply-dependence on demand conditions. It is a case of stimulus wins whereas austerity fails.
