This study argues that demand restrictions and involuntary unemployment arise from asymmetries between demand and supply in a monetary economy, and between the abilities of the firm and the household to adjust to market conditions. Fujino discusses the behavior of firms under uncertain demand; analyzes output-inventory, output-backlog, and fixed investment decisions; evaluates the approach to macroeconomic behavior of output and prices by means of aggregate supply functions; and details liquidity-preference and loanable funds theories of interest.
