Security Analysts’ Site Visits and Stock Price Synchronicity

This paper investigates how security analysts’ corporate site visits impact listed firms’ stock-price informativeness. Examining a sample of security analysts’ visits to Chinese listed firms from 2010 to 2019, we find that security analysts incorporate firm-specific information into share prices through site visits, significantly reducing the visited firms’ stock price synchronicity. This finding is robust to an alternative measure of stock price informativeness and a two-stage least-squares approach using the introduction of high-speed rail as the instrumental variable. We also find that the impact of analysts’ site visits on firms’ stock price synchronicity is more pronounced for firms with lower information disclosure quality and poor corporate governance than for other firms. Further analysis on firm characteristics documents that this effect is stronger for large-size firms, firms in the manufacturing industry, and state-owned enterprises.     

Effect of monumental heritage sites on hotel room pricing

This study measures the effect of historic monuments on hotel room pricing in Seville, Spain. A hedonic model including classic explanatory variables and the city’s heritage site was specified to explain hotel room rates. Variables related with heritage sites were determined to explain room rates and an iso-values map was obtained for the rates of a ‘standard hotel’ to show the impact of historic buildings on hotel rates. The maps display the area of influence of the heritage site. These results may be of interest to entrepreneurs, consumers, or the administration, among others, due to it permits them to determine which location maximizes rates.
