Now there is no part of our economic system which works so badly as our monetary and credit arrangements; none where the results of bad working are so disastrous socially; and none where it is easier to propose a scientific solution. (J. M. Keynes: Speech to the Liberal Party, December 1923, The...

In der Makroökonomik werden Liquiditätsfallen ohne Mikrofundierung als existent angenommen und die Japan-Krise hat Liquiditätsfallen wieder zum Diskussionsthema gemacht. Deshalb wird die Frage der Existenz von Liquiditätsfallen hier portfolio-theoretisch untersucht im Rahmen eines...

The sharp exchanges that Keynes had with some of his critics on the loanable funds theory made it harder to appreciate the degree to which his thought was continuous with the tradition of monetary analysis that emanates from Wicksell, of which Keynes's A Treatise on Money was a part. In the...

This paper revisits Keynes's liquidity preference theory as it evolved from the Treatise on Money to The General Theory and after, with a view of assessing the theory's ongoing relevance and applicability to issues of both monetary theory and policy. Contrary to the neoclassical "special case"...

This article is an attempt to formalize Chapter 17 of Keynes's General Theory using a continuous dynamic optimization model with perfect foresight. I Present two subjective interest rates: the time preference rate and the liquidity premuim that, respectively, govern the consumption-saving and...

Japan has suffered from sluggish economic growth and recession since the 1990s, a phenomenon dubbed "Japan's Lost Decade." The People's Republic of China, many countries in the eurozone, and the United States may face similar problems in future and they have been concerned by Japan's long-term...

This paper considers monetary and fiscal policy when tangible assets can be accumulated after shocks that increase desired savings, like Joseph's biblical prophecy of seven fat years followed by seven lean years. The model's flexible-price allocation mimics Joseph's saving to smooth consumption....

In HANK, we show that fiscal policy is an appropriate macroeconomic stabilization tool at the ZLB. Fiscal policy achieves the same macroeconomic aggregates and the same welfare as hypothetically unconstrained monetary policy by replicating its transmission mechanism. Consumption taxes and labor...

We show that in a New Keynesian model with household heterogeneity, fiscal policy can be a perfect substitute for monetary policy: three simple conditions for consumption taxes, labor taxes, and the government debt level are sufficient to induce the same consumption and labor supply of each...
