External shocks in a small open economy: an evaluation of monetary policy rules

This paper evaluates several small open economy DSGE models and the impact of external shock spillovers on small open economies. We investigate five small economies (the UK, Australia, Canada, New Zealand and Taiwan) and find that the welfare consequences vary depending on key domestic economic variables, and the best interest-rate rule varies across models. Then we examine the performances of the four types of models, a preferred result has been found in a model which considers the country risk premium, as the best rule could be obtained as long as the selected parameters are calibrated for particular economies

An Empirical Study of the Effect of Investor Sentiment on Returns of Different Industries

Studies on investor sentiment are mostly focused on the stock market, but little attention has been paid to the effect of investor sentiment on the return of a specific industry. This paper constructs a proxy variable to examine the relationship between investor sentiment and the return of a specific industry, using the Principle Component Analysis, and finds that investor sentiment is positively correlated with the industry return of the current period and negatively correlated with that of one lag period; we classify investor sentiment as optimistic state and pessimistic state and find that optimistic investor sentiment has a positive effect on stock returns of most industries, while pessimistic investor sentiment has no effect on them; this paper further builds a two-state Markov regime switching model and finds that sentiment has different effect on different industries returns on different states of market
