| dc.description.abstract (摘要) | 本文以簡化模擬金管會於2022年10月21日頒布的禁（限）空令為目標，利用Blanchard (1981) 的模型架構，建構一個小型開放經濟體系，與Blanchard (1981) 模型不同的是，為了令模型能夠更貼近禁（限）空令頒布時的背景，除了將外匯市場代入模型之外，也適當的調整股票市場的假設，使其符合「利空(bad news)」的條件。另外，為了能專注探討本文主軸即禁（限）空令的內容，故將民眾參與融券之行為納入股票市場，引入融券保證金及融券利率等兩大融券要素，在本國債券、本國股票與外國債券為完全替代資產的假設下，建立一個涵蓋商品、債券、股票與外匯等四個市場的開放經濟模型。最後，利用上述所建構的模型討論在政策改變下，理性的民眾將如何調整手中的資產。根據本文的研究，可發現（一）若調高融券保證金成數，將使股價上升，匯率不變，且長短期變化方向相同，不會產生錯向調整。（二）若提高融券利率，將使股價下跌，匯率不變，且長短期變化方向相同，不會產生錯向調整。（三）若外國政府執行緊縮貨幣政策，提高外國利率，在假設只能進行融券行為的「利空(bad news)」情況下，將使股價上漲，匯率提高，且長短期變化方向相同，不會產生錯向調整，其中股價可能會出現過度調整（overshooting）。（四）政策宣示當下，民眾的預期會隨即改變，使匯率與股價在政策宣示當下產生跳躍式的改變，但若宣示與政策的時間相距很久，則反映幅度相對較小，但在政策執行前一瞬間就會先反應至長期均衡。 | zh_TW |
| dc.description.abstract (摘要) | The purpose of this thesis is to simulate of the policy of limit shorting issued by the Financial Supervisory Commission on October 21, 2022. This paper analyzes the announcement effect of margin percentage and interest rate on short sale on the basis of Blanchard (1981) model. Different from the model of Blanchard (1981), the trade mode of short selling is imported in order to get closer to the background of the time and space. Under the assumption of the bear market and that domestic stock, domestic bond, and foreign bond are perfectly substitutable assets. We created a small open economy model covering commodity market, bond market, foreign exchange market and stock market. Finally, we discuss how the policy announcement effects human`s behavior on their asset allocation, resulting in the variation of stock prices and exchange rates. Several main findings emerge from the analysis. First, the effect of margin percentage for short sale on the long-run stock price is positive but doesn’t affect exchange rate. Second, the effect of interest rate on short sale for short sale on the long-run stock price is negative but doesn’t affect exchange rate. Third, under the premise of short selling function, both the long-run stock price and exchange rate mark up by raising foreign interest rate. Fourth, the policy announcement formulated by the government will change public expectations so that the stock price will respond immediately, and moreover, both the long-run stock price and exchange rate will react before the policy implementation. Additionally, the longer the interim is between policy announcement and implementation, the less reaction there are for the long-run stock price and exchange rate. | en_US |
