Does the risk of exchange rate fluctuation really affect international trade flows between countries?

This paper investigates the effect of exchange rate volatility on the UK's import trade. As part of econometric problems arising from a measured volatility, we consider a special case when an ARCH type auxiliary model is used to measure uncertainty in the exchange rate, and discuss a procedure for the correct inference of the OLS estimates of a primary equation in the second stage, which includes the generated variable. By applying this two-step approach, we find a statistically significant, negative impact of exchange rate uncertainty on Britain''s imports.ARCH model Consistent OLS estimation Exchange rate fluctuations International trade

The Effect of Exchange Rate Uncertainty on US Imports from the UK: Consistent OLS Estimation with Volatility Measured by An ARCH-type Model

This paper investigates the effect of exchange rate volatility on US-UK bilateral trade flows. As part of econometric problems arising from a generated variable, we consider a special case when an ARCH type auxiliary model is used to measure uncertainty in the exchange rate and discuss a procedure for the correct inference of the OLS estimates of the primary equation in the second stage, which includes the generated variable. By applying this two-step approach, we find a statistically significant, negative impact of exchange rate uncertainty on US imports from the United KinARCH model; Consistent estimation; Generated regressors; Volatility

The impact of inflation uncertainty on interest rates

In this paper, the impact of inflation uncertainty on interest rates is investigated for the case of the U.S. three-month Treasury bill rate. We emphasize how consistentOLS estimation can be applied to an empirical equation which includes a proxy variable of inflation uncertainty measured by an ARCH-type model. A significant negative relationship between the two variables is provided. This evidence is contrasted with the view of the inflation risk premium in which inflation uncertainty positively affects the nominal interest rate

The Effects of Extreme Weather Conditions on Hong Kong and Shenzhen Stock Market Returns

We investigate the impact of extreme weather conditions on the stock market returns of the Hong Kong Stock Exchange and Shenzhen Exchange. For the weather conditions, we apply dummy variables generated by applying a moving average and moving standard deviation. Our study provides two interesting results. First, extreme weather conditions have a significant impact on the stock returns of the Shenzhen Exchange, indicating that the Shenzhen market is inefficient. Second, during the pre-QFII period, extreme weather conditions have a strong impact on the returns of the Shenzhen stock market, but the impact is significantly weaker in the period after QFII. This means that the efficiency of the Shenzhen stock market has significantly increased since the QFII program due to the market openness to foreign institutional investors. We emphasize the role of foreign investors not affected by local weather conditions by observing how market opening affects extreme weather impacts on stock market returns

Dynamic Links Between Unexpected Exchange Rate Variation, Prices, and International Trade

This paper investigates dynamic interrelations between exchange rate uncertainty, international trade, and trading competitiveness in prices, using UK data. The empirical results derived from vector autoregressive (VAR) models show that a shock to exchange rate volatility negatively affects trade volumes, and such negative effects are greater than the effects on trade price levels.
