We analyze optimal patent design when innovators can rely on secrecy to protect their innovations. Secrecy has no fixed term but does not preclude accidental disclosure nor independent creation by other inventors. We derive the optimal scope of the rights conferred to such second inventors, showing that if the patent life is set optimally, second inventors should be allowed to patent and to exclude first inventors who have relied on secrecy. We then identify conditions under which it is socially desirable to increase patent life as much as is necessary to induce first inventors to patent. The circumstances in which it is preferable that they rely on secrecy seem rather limited . 相似文献

A formal model of productivity growth and technical progress is presented. The model takes into account embodied and disembodied technical progress as explanatory variables. The slowdown in productivity growth for the Spanish economy after 1972 is explained for 92% by the decline in the rate of growth of technical progress originated from domestic R&D and technology imports. 相似文献

Corruption, inequality, and fairness 总被引:1,自引:0,他引:1
Bigger governments raise the possibilities for corruption; more corruption may in turn raise the support for redistributive policies that intend to correct the inequality and injustice generated by corruption. We formalize these insights in a simple dynamic model. A positive feedback from past to current levels of taxation and corruption arises either when wealth originating in corruption and rent seeking is considered unfair, or when the ability to engage in corruption is unevenly distributed in the population. This feedback introduces persistence in the size of the government and the levels of corruption and inequality. Multiple steady states exist in some cases. 相似文献

We make the point that preferences for democracy are positively correlated with level of education. This correlation is robust even after controlling for a range of personal characteristics, including country of residence, income, age, or using different definitions of preferences for democracy or using instrumental variables. Interestingly, the results hold across countries with different level of democracy. We use data from World Values Surveys and show that our results are consistent with a simple theoretical model in which education makes political accountability easier. 相似文献

We develop a timing game for adopting a product technology that features a public good. We investigate the effects of the degree of product market competition, product differentiation, the private benefits from contributing to the public good, and firm asymmetries on the timing of adoption. We then examine the effects of consumer subsidies on equilibrium timings and the proliferation of the public good. 相似文献

This paper is aimed at contributing to the literature on income and wealth inequality by proposing a simple stochastic model in which wealth accumulation depends on the ‘social relation’ between two classes: capitalists or workers. As a result, the society may evolve towards an unequal outcome with few rich and many poor individuals. We study the dynamic properties of the model by means of computer simulations. A maximum likelihood estimation procedure is applied to analyse the Pareto or power law tail of wealth distribution. We also provide a scenario analysis to explore the system's behaviour under alternative parameter settings. 相似文献

Following a partial equilibrium approach, this paper studies the effect of fiscal policy on income distribution in Argentina, based on budget information corresponding to the year 2004. Specifically, it aims to provide an empirical answer to a set of questions related to the responsibility of different levels of government (national or provincial) in ensuring the equitable distribution of income; how this responsibility is accomplished in practice, when this function is shared among two or more levels of government; whether an incompatibility arises among the policies from different levels of government; and the effect of fiscal policy on personal and regional income distribution.The main results of the paper are summarized as follows. At the aggregate level, both national and provincial budgets have a redistributive impact on personal income distribution, through a combination of progressive expenditures and (slightly) regressive taxes. Regional redistribution depends on two fiscal tools: the national budget and the revenue sharing regime. The progressive effect of expenditures and taxes interacts with the geographical effect of the revenue-sharing and the national budget, reinforcing progressivity in net-receiving groups and creating a trade-off between progressivity and (negative) regional transfer in net-financing ones. Provincial budgets have more impact than the national budget, both being compatible in pursuing the redistributive goal. 相似文献
