本計畫在中間財市場為獨占性競爭，中間財廠商家數內生，且中間財種類對於 最終財產量具有規模報酬效果的成長模型中，探討最適貨幣與租稅政策的制訂，並 與既有文獻比較，討論傳統貨幣政策，傅利曼法則 (Friedman Rule)的頑強性。同時， 本計畫也將在競爭均衡下，探討租稅政策與貨幣政策的成長效果，及商品市場的競 爭程度對於政策效果的影響。

At the same time, another subject is to investigate the effect of income tax and the rate of money creation on economic growth and the relationship between these policies effectiveness and the degree of imperfect competition.
