ENThis paper investigates the determinants of aggregate service exports and the determinants of 7 service subcategories (i.e. transport, travel, communication, computer & information, financial, construction and other business services) of Lithuania using a gravity model and a panel dataset for the 2003-2012 period. First, a general gravity model for total exports is specified. Then, the general gravity model is augmented for each service subcategory by including additional variables that are specific for each service subcategory and that capture the features of each type of service. The results show that GDP of the destination country and a common spoken language exert a positive effect on trade in services. Time zone differences, EU membership and relative human capital are found to have a heterogeneous effect across service subcategories. Also, the significance of physical distance between Lithuania and its partners varies in dependence of the type of service. Remoteness of the destination country is found to be insignificant for the majority of service subcategories, except transport services, other business services, and computer & information services. Keywords: determinants of exports, exports of services, gravity model.
