美國利率與美國股市 - 經濟

: Thanks for correcting my grammar. It is helpful to me. Thank you very much.
: A question here is the relationship between interest rate and stock market.
: Recently, I read two papers (Rapach et al., 2005; Rapach & Wohar, 2006)
: about the predicting stock returns with macro and financial variables.
: Using monthly and quarterly data, the empirical results show that the lag of
: interest rate can predict the stock returns, and the regression coefficient is
: negative and significant. However, the R-squared is pretty low.
: Thus, you are right in the argument that it is not easy to predict the stock
: returns even the regression coefficient is significant. However, according to
: the previous literature, the relationship for these two variables is negative.
: In fact, there are two potential problems in previous studies. First, they use
: lag of interest rate (term rate, default spread, shot rate, relative rate) to
: predict stock returns, so they find a negative relationship between the interest
: rate and stock returns. If we use the simultaneous regression model, we may
: find a different story (However, I think this possibility is relative low).
: Second, previous studies use the level interest rate to predict stock returns.
: As we know, the interest rate might be a non-stationary process. There may
: exist a spurious regression in the previous studies. Similarly, I think this
: potential econometric problem is considered in Rapach et al (2005) and
: Rapach and Wohar (2006) since Rapach familiarizes with econometric model.
: I am not an economist. I just point out the potential problems.
: So if you have any comment or suggestion on this issue, I will very happy
: to discuss with you. Moreover, if you are interested in this issue,
: I have the data used in Rapach et al (2005) and Rapach and Wohar (2006) so that
: I can share with you.
: Thanks agian for correcting my errors. If I have any error in this article,
: you are welcome to point out that.
: Sincerely,
: H-S Lee

我想，這個議題大家有自己的看法，

我只是引起用過去文獻，告知大家這個議題過去的研究結果，

和過去研究的潛在問題。

大致是這樣。

關於英文寫作，我必須還是要練習啦，請大家包含和指導，
