We examine the effects of public funding on higher education within a game-theoretical framework, in which universities choose students according to their abilities to learn, whereas to widen the opportunity of receiving higher education, the tuition fees are partially financed by a graduate-tax...

This article models a North--South negotiation where the North provides a <italic>quid pro quo</italic> in exchange for the strengthening of the enforcement of intellectual property rights (IPR) protection in the South. We show that when Northern and Southern firms compete on quantity in the Southern market, the...

We aim to generalize the results of Cai and Nitta (2007) by allowing both the utility and production function to depend on time. We also consider an additional intertemporal optimality criterion. We clarify the conditions under which the limit of the solutions for the finite horizon problems is...

We aim to construct the optimal solutions to the undiscounted continuous-time infinite horizon optimization problems, the objective functionals of which may be unbounded. We identify the condition under which the limit of the solutions to the finite horizon problems is optimal for the infinite...

Higher-order optimization problems naturally appear when investigating the effects of a patent with finite length, as in the pioneering work of Futagami and Iwaisako (2007). In this paper, we establish the Euler equations and transversality conditions necessary for analyzing such higher-order...
