This paper develops a trade model in which two heterogeneous firms located in two different countries make their productivity choices by choosing their optimal R&D investment levels and then make a mode choice between exporting, licensing and FDI under Cournot competition in an open economy. The ex-ante difference in the cost efficiency of two firms will lead to difference combinations of ex-po...

Overseas Chinese family businesses (OCFBs) have gained a reputation for cost efficiency, responsiveness, and flexibility as original equipment manufacturers (OEMs) and as pioneers of the mainland's industrialization. This success is based upon a relatively simple 'personally managed' organization operating within a network of kin and ethnic relations. To what extent are mid-sized OCFBs now able...

Recent empirical studies and analyses have heightened interest in the use of expanded antiretroviral therapy (ART) for prevention of HIV transmission. However, ART is expensive, approximately $600 per person per year, raising issues of the cost and cost-effectiveness of ambitious ART expansion. The goal of this review is to equip the reader with the conceptual tools and substantive background n...

The costs that species suffer when deceived are expected to drive learned resistance, although this relationship has seldom been studied experimentally. Flowers that elicit mating behaviour from male insects by mimicking conspecific females provide an ideal system for such investigation. Here, we explore interactions between a sexually deceptive daisy with multiple floral forms that vary in dec...

Pay-for-performance (P4P) pricing schemes such as pay per click and pay per action have increased in popularity in Internet advertising. Meanwhile, pay-per-impression (PPI) schemes persist, and several publishers have begun to offer a hybrid mix of PPI and P4P schemes. Given the proliferation of pricing schemes, this study examines the optimal choices for publishers. The authors highlight two-s...
