Sraffian supermultiplier models (SSM) try to identify autonomous components of demand. The most plausible candidate is government consumption. Descriptively, however, government consumption does not grow at a constant rate, and prescriptively there is no justification for keeping constant the...

This paper examines the dynamics of Keynesian models that incorporate feedback effects from the labor market to income distribution, investment, aggregate demand and output. A baseline version of the model can generate endogenous growth cycles, but cumulative divergence and economic collapse...

Fiscal policy and public debt may be required to maintain full employment and avoid secular stagnation. This conclusion emerges from a range of different models, including OLG specifications and stock-flow consistent (post-) Keynesian models. One of the determinants of the required long-run debt...

This paper makes three main points. Fiscal policy, first, may be needed in the long run to maintain full employment and avoid secular stagnation. If fiscal policy is used in this way, second, the long-run debt ratio depends (i) inversely on the rate of growth, (ii) inversely on government...

Successful economic development to a large extent derives from the mobilization of underemployed resources. Demand policy can play an important role. It is critical, however, to consider balance of payments constraints and to ensure an expansion of investment in the modern sector. A combination...
