Optimal Tariffs with Endogenous Production Location

This paper attempts to examine how the inclusion of economic space affects trade policies and to make a comparison between optimal tariffs with endogenous location and those with exogenous location. In particular, it is shown that the output effect of a tariff change with endogenous location is greater than that with exogenous location if the production function is non-CRS. Moreover, when the production function is CRS (resp. not CRS), the optimal tariff under endogenous location is the same as (lower than) the one under exogenous location.

Experiential goods with network externalities effects: An empirical study of online rating system

This paper uses online users' reviews and sales information from May 2003 to March 2007 to study a new experiential product: online video game (or virtual world). The results suggest that, first of all, for a hedonic product such as an online video game, the availability of online review system could not fully transform experience attributes into search attributes. The empirical study confirms that negative word-of-mouth has more significant impact than positive reviews. The study empirically verifies that the existence of direct network externalities (i.e. a product's value increases when more consumers join the network) is crucial for a hedonic product. The size of the user base signals the quality of the game, and works like a search attribute for potential users. A large user base will reduce the negative impact from unfavorable reviews.     

Born-global: The case of four Vietnamese SMEs

Despite the fact that many firms in a wide range of industries in various countries internationalize at or near inception, research on factors leading to the formation of born-globals has been limited to firms from advanced, open economies. In order to give a voice to the phenomenon of Vietnamese founding born-globals, we conducted an exploratory, multiple-case study. Three findings of this study are: (1) the major driver to the formation of Vietnamese born-globals is the entrepreneurs’ leadership desire together with the need for short-term profits; (2) their choice of internationalization mode is influenced by market conditions as well as the internationalization degree of the industries in which they find their business opportunities; and (3) the reason why other motivators found in earlier studies do not apply lies in the peculiarity of the Vietnam context.
