摘要:	在這次的研究計畫中，我們企圖分析貨幣政策在搜尋與配對模型下，對失業、資本累積、成長率與社會福利的影響效果。為了分析這些問題，這多年期(二年期)計畫擬將資本累積融入 Berentsen-Menzio-Wright 模型。第一年的議題著重於通貨膨脹在新古典成長模型之中，對失業與資本的短期動態效果與長期均衡效果為何。直覺而言，較高的名目利率將造成家計單位持有貨幣的成本增加，以致廠商有較低的獲利，以及廠商在勞動市場中降低釋放職缺的意願，進而提高了失業率，降低了資本邊際生產力與資本的存量。第二年的議題探究貨幣政策在內生成長模型之中，對經濟成長與社會福利的影響效果為何。直覺而言，較高的名目利率將降低資本的存量，進而對經濟成長有負向衝擊。另外，本計畫也檢測，所得稅為財政政策工具時，Friedman 法則是否依然成立。最後，我們將量化分析政策的福利效果。 In this project, we attempt to analyze the effects of monetary policy on unemployment, capital accumulation, growth and social welfare in a search-and-matching model. To analyze these effects, this 2-years project will consider the Berentsen-Menzio-Wright model and introduce capital accumulation into this model. In the first year, this project focuses on the short-run dynamic and the long-run equilibrium effects of inflation on unemployment and capital per worker in a standard Neoclassical growth model. Intuitively, an increase in the nominal interest rate increases the amount of money holdings by households. Due to the resulting lower profitability, firms have less incentive to create vacancies in the labor market, which in turn leads to higher unemployment. The smaller number of employed workers depresses the marginal product of capital and in the long run decreases the capital stock. In the second year, this project explores the effects of monetary policy on economic growth and social welfare in an endogenous growth model. Intuitively, an increase in the nominal interest rate decrease the capital stock, in which in turn leads to a lower growth rate. In addition, this project also examines whether the Friedman holds if we consider the income tax. Finally, we will make an effort to provide a quantitative analysis on the welfare effects of policies.
