Sequencing R&D decisions in a two-period duopoly with spillovers

Experimental Research on Asymmetric R&D Investment of R&D/Product Problem

“…In R&D/product problem model, taking A&J (d'Aspremont & Jacquemin） as an example [5], two representative enterprises (i to be local enterprise and j to be MNE) are involved. Enterprise i's effective R&D effect is assumed to be the sum of its own R&D effect i x and a proportion of its rival's R&D spillovers j x  , (  is the spillover coefficient).…”

Leader, Follower: Strategic Investments with Asymmetric Spillovers

“…Model 4 is the usual setting in most of the strategic investment literature (see De Bondt (1997)). Model 3 has been looked at as well (see Amir et al (2000)). …”

“…The comparison of the investment incentives of the leader and the follower in model 3, which has been analyzed by Amir et al (2000), can be described by using proposition 5. …”

“…But in reality, firms may be engaged in first mover efforts, while others imitate, catch up or even leapfrog on pioneering moves (Halmenschlager 2004). Spillovers between leaders and followers will tend to be asymmetric, and may carry direct negative and positive effects and may influence role playing (Amir, Amir and Jin 2000).…”

Determining workspace parameters for a new type of 6RSS parallel manipulator based on structural and geometric models

“…Regardless of the number of degrees of freedom, fewer [1][2][3][4][5][6][7][8] or more [9][10][11][12], the parallel mechanisms have proven their utility in various domains such as flight simulators, telescope position control, radar antennas, pointing devices [13].Parallel mechanisms have a robust construction and can move bodies of considerable mass and size at high speed, establishing a translational motion or rotation of the mobile platform. Compared to serial mechanisms, parallel manipulators have some special characteristics: high rigidity, high dynamic loading capacity, chain closed structure, high positional accuracy.…”
