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 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...

Using a money-in-the-utility-function model, we present long-run stagnation where insatiable demand for money secularly causes deficient aggregate demand and thereby unemployment in the presence of nominal wage stickiness attributable to union wage setting. In this long-run stagnation, generous...

In 1960s - 1980s Japan enjoyed high economic growth. In the early 1990s, however, the growth rate drastically declined and thereafter Japan has been suffering secular stagnation. This paper proposes a dynamic macroeconomic model that can consistently explain such a drastic change in economic...

Using a dynamic two-country two-commodity Ricardian model where preference for money (or wealth) leads to aggregate demand deficiency, this paper examines the relationship between the two countries' relative population size and their specialization patterns, employment and consumption. When the...
