This paper investigates the effect of different patent regimes on R&D investment and social welfare in a duopoly market with uncertain R&D process. We find that strong patent protection increases R&D investment of at least one firm but whether both firms’ R&D investment will be more under strong patent protection is ambiguous. While ex-ante welfare is more likely to be higher under strong paten...

By using the sources of investment and based on provincial data, this paper examines the efficiency performance of the four sources of total investment in fixed assets in China for the period 1985–1998: state budget appropriation, national bank loans, self-raised funds, and foreign investment. The result of the panel data study shows that the growth of provincial output is positively related to...

a r t i c l e i n f o This paper contributes to the literature by identifying the causal effect of firm investment on exporting behavior. The identification hinges on regional variations in the 2004 value-added tax pilot reform in China, which generated positive investment shocks. The instrumental variable estimation results show that firm investment significantly and substantially increases th...

In tlus paper we consider an investment strategy called dollar-cast-averaging (DCA). It is well known that the argument in favor of DCA is flawed: an investor cannot get something for nothing. Probabilists have made tltis type of flaw precise with theorems like the optional sampling theorem or, more generally, the martingale system theorem (see e.g. [4]). It is interesting that the usual martin...

The ‘precise’ information frame has exact probabilities and exact payments stated. In the ‘ambiguity in probability’ frames, the probability is stated as a range and the payment is fixed. Conv...

This paper empirically examines whether additional future fixed capital and R&D investment expenditures induce firms to accumulate cash reserves while considering the role of market imperfections. Implementing a dynamic framework on a panel of US, UK and German companies, we find that firms make larger additions to cash holdings when they plan additional future R&D rather than fixed capital inv...

On an investment-consumption model with transaction costs, SIAM J. Abstract. This paper considers the optimal consumption and investment policy for an investor who has available one bank account paying a fixed interest rate and n risky assets whose prices are log-normal diffusions. We suppose that transactions between the assets incur a cost proportional to the size of the transaction. The prob...
