Getting Economics to Acknowledge Rentier Finance

The economics discipline has for the most part managed to ignore the 800 pound gorilla in the room: that of the role that the financial services industry has come to play. Astonishingly, even though the reengineering of the world economy along the lines preferred by mainstream economists resulted in a prosperity-wrecking global financial crisis and a soft coup by financiers, the discipline carries on methodologically as if nothing much had happened. And one of its huge blind spots is its refusal to acknowledge the role of banking and finance in modern commerce. Interest rates are simply an input into the preferred form of macro models, DSGE (dynamic stochastic equilibrium models). Economies are assumed to be self correcting, and to automagically “correct” to full employment. All shocks to the system are exogenous. In other words, boom-bust credit cycles are simply omitted because they are ideologically inconvenient and instability is too hard to model.
