Strategies which are robust against indirect invasions (RAII) have been studied in the literature for symmetric games. In this paper, we introduce the notion of RAII profiles for asymmetric games with continuous strategy spaces. For these games, we prove that the set of all indirect neutral mutants of a RAII profile is equivalent to a minimal evolutionarily stable set. Furthermore, globally strong uninvadable profiles are shown to be RAII profiles. We also discuss connections between evolutionarily stable sets and strict equilibrium sets of profiles.

In this paper, we formulated a dynamic game model of the firms’ process innovation with technological spillover under different market structures (market competition intensity) in a duopoly market, in which the firms are concerned about relative profits as well as their own profits and investigated the relationship between the degree of competitiveness faced by the firms and their R&D expenditure. Our results showed that, under certain conditions, the system always admits saddle point steady-state equilibrium under independent ventures and R&D cartel games, respectively, and although the process innovation investment under R&D cartel is higher than that under the independent ventures, whether the marginal production cost under R&D cartel is less (higher) than that under the independent ventures depends on the degree of technological R&D spillover and the market competition intensity. Furthermore, the marginal production cost under independent ventures is not monotonically decreasing with spillover for the given region of market competition intensity; while the marginal production cost under R&D cartel game always monotonically decreases with spillover for any market competition intensity.

Pavel Naumov, I. Simonelli
This paper proposes a novel way to compare classes of strategic games based on their sets of pure Nash equilibria. This approach is then used to relate the classes of zero-sum games, polymatrix, and k-polymatrix games. This paper concludes with a conjecture that k-polymatrix games form an increasing chain of classes.
