We compare ultimatum bargaining behaviour between Tibetans in Lhasa and ethnic Han Chinese in Xiamen with a focus on identifying how cultural traits and religious beliefs affect behaviour. A control group in Singapore was used to account for possible non-cultural explanations for the observed behavioural differences. It was found that, compared to Han Chinese, Tibetans are more likely to accept offers in the ultimatum game and that their decisions are unrelated to the actual offer size. [Copyright Elsevier B.V.]

We study and contrast pricing and price evolution of online only (Dotcom) and online branch of multi-channel retailers (OBMCRs) based on two panel data sets collected from online toy markets. Panel data regression analyses reveal several interesting empirical results: over time, OBMCRs and Dotcoms charge similar prices on average but Dotcoms significantly increase their shipping costs that eventually drive the overall average price of Dotcoms higher than that of OBMCRs. Price dispersions of both types of retailers are persistent. The price dispersion of OBMCRs is higher than that of Dotcoms at the beginning and does not change much over time, but the price dispersion of Dotcoms increases significantly over time, indicating that the latter will eventually be higher than the former. Moreover, the OBMCRs charge significantly different prices, but the Dotcoms charge similar prices.

We examine the pricing trends in the online toy markets by using panel data regression models with error components and serial correlation. Our results indicate that both online branch of multi-channel retailers (OBMCRS) and dotcoms charge similar prices on average, and that over time their prices move in tandem. Although the OBMCR retailers charge significantly different prices, the dotcoms do charge similar prices. Moreover, both retailer types demonstrate different magnitudes of price dispersion that move at different rates over time. Although the price dispersion of OBMCRS is higher than that of the dotcoms at the beginning, the gap narrows over time.
