Growth and optimal policies in an R&D-growth model with imperfect international capital mobility

In this paper, we examine the effects of international capital mobility on innovation, growth, and optimal growth policies in a small open economy with R&D-driven growth. Households can borrow funds from an imperfect international capital market to finance their investment in R&D firms. We show that the economy can reach a higher growth rate if international capital is more mobile. This result is consistent with recent empirical findings. Moreover, we show that the common growth-enhancing policies, such as patent protection and the R&D subsidies, have an additional negative welfare effect when households can access the international capital market. Accordingly, the optimal patent protection and R&D subsidy should be smaller when the degree of international capital mobility is higher.     

Love thy neighbour: Evidence from capital structure decisions

We examine how the peer effects arising not only from the leading firm but also from a slightly better performing firm affect the capital structure decisions of a firm. There is a large body of literature documenting the importance of peer effects, but it is unclear whether managers pay close attention to activities of slightly better performers. This study uses both book- and market-value based approaches to estimate the peer effect measures. Our analysis shows that: (1) our peer effect measures induce the convergence of the follower firms' capital structure towards better performing firms; and (2) the capital structure converges more towards a slightly better performer.
