Krugman has recently revitalized IS-LM with a number of succinct analytical pieces on his blog. The reverberations were remarkable. Economists, however, are known often not grasp the full content of their own and, a fortiori, of others' models. This happened to Keynes in the days of high theory...

This note proposes a growth model that is derived from the standard Solow growth model by replacing the neoclassical production function with Kaldor's technical progress function while maintaining a marginalist theory of factor prices in the spirit suggested by von Weizsäcker (1966, 1966b). The...

The paper shows how increases in the inflation rate can cause the output growth rate to decrease by a lessor amount as the inflation rate rises. This is the so-called non-linearity in the inflation-growth effect. Our explanation helps show how model-based estimates of the inflation-growth effect...

This paper presents a simple Ramsey-type model example where two infinitely-living agents have same utility function except for time preference, and shows that equilibrium is indeterminate that is to be interpreted as being non-existent. The issues regarding New Keynesian transversality...

This paper studies a modern monetary economy: trade in both goods and securities relies on money provided by intermediaries. While money is valued for its liquidity, its creation requires costly leverage. Inflation, security prices and the transmission of monetary policy then depend on the...

The paper presents a theory of the demand for money that combines a special case of the shopping time exchange economy with the cash-in-advance framework. The model predicts that both higher inflation and financial innovation - that reduces the cost of credit - induce agents to substitute away...
