The Robertson connection between the natural rates of interest and unemployment

The paper explores the connection between the natural rates of unemployment and interest first put forward in the literature by Dennis Robertson in the 1930s. This looks at monetary dynamics in the business cycle and assesses the Robertsonian contribution to developments in macroeconomics before and after Keynes's General Theory. Robertson showed how unanticipated price level changes affect supply and demand in the labour market, as well as the saving–investment process in the credit market. Robertson's approach to economic policy was that of getting the relations right between cyclical changes in prices, output and employment and their long-run equilibrium values over time.
