Price Variability and Industrial Concentration in U.S. Food Industries

This paper focuses on the sources of intra‐industry price variability in US food industries during a period of increasing concentration, while accounting for the impact of variations in prices of primary agricultural products. Results suggest that intra‐industry price variability in food industries increases with their respective mean rate of inflation and product heterogeneity. However, industrial concentration lowers the sensitivity of relative prices to changes in the mean rate of inflation. Hence, static welfare losses to consumers from increasing concentration in food industries, a subject of recent and intensive investigation, can partly be offset by gains such as reduced price variability.

Cross-Listings and Home Market Trading Volume: The Case of Malaysia and Singapore

Cross‐listings of equities internationally are becoming more common. Using data for Europe and North America, previous studies reject the order flow diversion hypothesis, which states that international cross‐listings reduce home‐country trading volume. We test this hypothesis using data for equities cross‐listed in Singapore and Malaysia. We find that trading volume in Malaysia fell 42.9% when Singapore markets were closed for holidays. Furthermore, we show that trading volume in Malaysia did not increase following the implementation of regulations that ended the trading of Malaysian equities in Singapore in 1998. Hence, we reject the order flow diversion hypothesis.
