We develop a Keynesian cross analysis with a dynamic optimization setting that explains long-run stagnation caused by aggregate demand deficiency. We show that an increase in government purchases boosts GDP through a multiplier process, but the implication is quite different from the...

We propose a microeconomic foundation of the multiplier effect and that of the consumption function using a dynamic optimization model that explains a shortage of aggregate demand and unemployment. We show that government purchases boost aggregate demand through a multiplier-like process but...

We consider a dynamic macroeconomic model with 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 results: with the ratio specification full...

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...

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 public works spending may...

Although the Keynesian multiplier effect of public works is criticized for lack of a microeconomic foundation, it is still taught in most undergraduate courses and believed to be useful for policy makers. However, it has a serious fallacy even if we accept the consumption function. This note...

We present a dynamic and monetary model that consistently explains such various phenomena as unemployment, deflation, zero nominal interest rates and excess reserves held by commercial banks. These phenomena are commonly observed during the Great Depression in the United States, the recent...

We develop an aggregate demand analysis of a small open economy based on all agents' dynamic optimization. Murota and Ono (2015) present a simple Keynesian cross analysis with dynamic optimization. This paper extends it to a small-country setting with two factors and two commodities, of which...
