This paper constructs a model that describes inflation cycles and prolonged depression as generated by the learning behavior of households who face a random liquidity shock in which money is needed. Households update the subjective probability of the shock based on the observation and change...

This paper examines a mechanism of liquidity-preference fluctuations caused by people's learning behavior. % about the frequency of a liquidity shock. When observing a financial shock, they rationally update their belief so that the subjective probability of encountering it again is higher,...

This paper presents a simple model in which the learning behavior of agents generates fluctuations in money demand and possibly causes a prolonged depression. We consider a stochastic Money-in-Utility model, where agents receive utility from holding money only when a liquidity shock (e.g., a...

When a continuum of technologies is introduced to the model of Grossman and Helpman (1991), both continuous and discrete technological progress may occur as a result of technology choices by private firms. A good is created through R&D based on one of a continuum of technologies that differ in...

We consider a dynamic macroeconomic model of households that regard relative affluence as social status. The measure of relative affluence can be the ratio to, or the difference from, the social average. The two specifications lead to quite different@equilibrium consequences: under the ratio...

This paper presents a two-country two-commodity dynamic model with free international asset trade in which one country achieves full employment and the other suffers long-run unemployment. Own and spill-over effects of changes in policy, technological and preference parameters that emerge...

Determinacy of equilibrium under the original, the backward-looking, the forward-looking and the hybrid Phillips curves is examined. If the monetary authority keeps the nominal money stock to be constant, the equilibrium path is always determinate under the original Phillips curve and the...

The Keynesian multiplier effect is reinterpreted and several issues that may have misled assessments of the effect of fiscal spending are discussed. It is shown that even in the textbook Keynesian framework some transfer policy 'reduces' aggregate demand and that publ works spending may...

We consider three objects of people's status preference, consumption, physical capital holding and money holding, and show that an economy grows or stagnates depending on which object people most seriously take as status. If the main object of status preference is consumption, a steady state...
