The conventional wisdom about Keynes's Principle of Effective Demand is that it states something about quantities. It is widely held that the Principle determines the levels of output and employment in a world not governed by Say's Law. This paper argues that the Principle of Effective Demand...

We define the notion of 'de facto fiscal space' of a country as the outstanding public debt relative to the de facto tax base, where the latter measures the realized tax collection, averaged across several years to smooth for business cycle fluctuations. We apply this concept to account for the...

This paper uses a simple new-Keynesian model (with and without capital) and calculates multipliers of four types. That is, we assume either an increase in government spending or a cut in sales/labor/capital tax that is financed by lump-sum taxes (Ricardian evidence holds). We argue that...

The output multiplier turns negative before a deficit spending program expires. We show the generality of this unpleasant finding for the standard real business cycle model. We then calibrate an extended model for the US and demonstrate how fiscal stimulus slows down economic recovery from...
