| Research Abstract |
I discussed the relationship between business-to-business transactions(vertical market) and the effects of merger(vertical integration and horizontal merger). I obtained the main results as follows.(1) I analyzed equilibrium vertical integration with complementary input markets.(2) I showed that large firms tend to integrate vertically.(3) I discussed the relationship between the decision of direct marketing and the number of retailers.(4) I showed that competitive pressure in upstream market may increase the profit of upstream firms.(5) Using an event study approach, I considered market definition of long distance transportation market in Japan.
