We investigate how corporate stock returns respond to geopolitical risk in the case of South Korea, which has experienced large and unpredictable geopolitical swings that originate from North Korea. To do so, a monthly index of geopolitical risk from North Korea (the GPRNK index) is constructed...

Indirect network effects exist when the utility of consumers is increasing in the variety of complementary products available for use with an electronic hardware device. In this paper, we examine how trade liberalization affects production structure in the presence of indirect network effects....

The main purpose of this study is to illustrate, with a simple two-factor (skilled and unskilled labor) model, how a time-saving improvement in business-services trade benefitting from differences in time zones can have an impact on national factor markets. In doing so, we intend to capture the...
