This paper examines the international mixed duopoly behaviour with research spillovers. Using a two‐stage game with Research and Development (R&D) and output, we investigate the effects of imperfectly appropriable R&D on optimal R&D strategies of a domestic public firm and a foreign private firm across different market interactions: (i) international R&D competition, (ii) only the foreign firm conducts R&D, (iii) only the domestic public firm conducts R&D, (iv) no firm conducts R&D, and (v) research joint venture. The results show that firms' research performances are determined by the degree of spillovers and the optimal R&D strategies involve R&D competition. Spillovers are shown to be socially beneficial and their absence can prove to be a strategic deterrent, with the public firm monopolising the market. Some of these findings contrast with the traditional models of oligopoly (with or without R&D) and mixed oligopoly (without R&D).  相似文献

We employ a three-stage game model with cost-reducing research and development (R&D) that is subject to spillovers to consider the problem of excess entry under free-entry equilibrium relative to the social optimum. Firms choose to enter or exit a market in the first stage, choose R&D in the second stage and output in the final stage. Results show that there is socially inefficient or excessive entry in equilibrium. However, we uniquely demonstrate that research spillovers hold the key to whether established results regarding socially inefficient entry hold. Specifically, excessive entry occurs as long as research spillovers are relatively small, but this is not necessarily the case with large spillovers. Some policy implications are discussed.  相似文献

The 2023 Sustainable Development Goal Report reveals that Africa is still struggling in its pursuit to achieve universal healthcare coverage. However, financial risk protection and human capital development could come to the rescue by facilitating the attainment of quality healthcare services. This study examines the effect of financial inclusion on healthcare in Africa, spanning from 2000 to 2021. Healthcare is proxied by life expectancy at birth, the immunisation rate, and the lifetime risk of maternal death. Financial inclusion is approached through access and usage of financial services. After controlling for the problem of potential endogeneity through the system generalised method of moment (GMM), the findings reveal that financial inclusion enhances healthcare in Africa, signifying that financially included individuals have a higher conditional probability of spending more on improving their health relative to the financially excluded individuals. Moreover, the findings indicate that education and technology diffusion are imperative in the quest for enhancing healthcare in Africa. In addition, after testing for sensitivity analysis by adopting different indicators of healthcare, the results remain consistent throughout the study, confirming the role of financial inclusion in enhancing healthcare in Africa. After computing the marginal effects, the findings depict that education and financial inclusion interact to produce positive synergy effects, signifying that the positive role of financial inclusion and education in enhancing healthcare outweighs the negative conditional effect. The results recommend policymakers establish a framework that promotes financial literacy for the enhancement of healthcare in Africa.  相似文献

In this paper, we examine international technology diffusion by using patent citations as a proxy for technology diffusion. We focus on some Asian economies, i.e., Korea, Taiwan, China and India, to investigate the relationship between technology diffusion and their trade experience with the U.S., Japan, and other G7 countries. Our empirical results reveal that trade specialization has a significant correlation with technology diffusion. Some policy implications are discussed.  相似文献

ABSTRACT

The paper employs the multipurpose nature of mobile telephony to investigate its welfare implications using a large sample of households in Ghana. We use seemingly unrelated probit and instrumental variable procedure to test for two related issues: First, we investigate whether mobile telephony promotes pro-poor development by helping households to efficiently allocate consumption and navigate out of poverty. Second, we analyze whether access to a broad array of financial services enhances the capacity of households to live worthwhile lives. The results show that mobile penetration and financial inclusion significantly reduce the probability of a household becoming poor and increase per capita household consumption of food and non-food items. Our results show that the welfare benefits of mobile telephony and financial inclusion are not more pronounced in female-headed households. These insights serve as useful guide for government and other stakeholders who are looking for avenues to improve livelihoods.  相似文献

This research focuses on the behavior of not-for-profit enterprises. In particular, using a familiar model of cost-reducing R&D with spillovers, we examine strategic interactions between labor-managed firms in a duopoly. Research spillovers have not been previously considered in the context of labor-managed firms. Among four market scenarios involving (i) competition in research and production; (ii) cooperation in research and production; (iii and iv) competition or cooperation in research and the reverse in production, our results show that research is greatest under full cooperation, while output is greatest under full competition. Output and R&D are the lowest in the case when firms compete in research, but form a production cartel. The degree of research spillovers has a crucial bearing upon these rankings. Some of these results differ from those for profit-maximizing firms. The effects of changes in research spillovers on employment (output) are shown to depend upon the nature of the underlying production technology. Policy implications are discussed.  相似文献

We study optimal pollution abatement under a mixed oligopoly when firms engage in emissions‐reducing research and development (R&D) with imperfect appropriation. The regulator uses a tax to curb emissions. Results show that in a mixed oligopoly, the public firm has positive emissions reduction in equilibrium; however, emissions reductions of the private firm could be positive or zero. Under certain conditions, the optimal pollution tax is positive; otherwise, the tax reverts to a subsidy. Comparing mixed and private duopolies, privatisation leads to reductions in R&D and output, but to an increase in overall emissions, so privatisation tends to make the environment worse.  相似文献

Mobile money (MM) services can contribute to welfare gains in smallholder farm households. Previous research showed that one important pathway for these MM‐related welfare gains is through higher remittances received from relatives and friends. Here, the role of other impact pathways is examined, especially focusing on agricultural marketing and off‐farm economic activities. The analysis builds on panel data from smallholder coffee farmers in Uganda. Regression models show that the adoption of MM technology has contributed to higher household incomes and consumption levels. Off‐farm income gains are identified to be an important pathway, also beyond remittances. Typical off‐farm income sources are small businesses in trade, transport, and handicrafts, which benefit from novel savings and money transfer opportunities through MM. In terms of agricultural marketing, MM users sell a larger proportion of their coffee as shelled beans to buyers in high‐value markets, instead of selling to local traders immediately after harvest. MM services help to reduce cash constraints and facilitate transactions with buyers from outside local regions. In conclusion, MM can contribute to rural development through various important pathways. Analysis of adoption patterns suggests that MM services are socially inclusive.  相似文献

We examine whether deep regional trade agreements facilitate cross-border licensing. A micro-founded gravity equation for each supply mode is derived from a model in which heterogeneous firms choose to supply their goods to foreign markets through export, foreign direct investment or licensing. We present several comparative statics results regarding the effects of changes in the fixed costs of serving the destination country, the freeness of trade, and the strength of intellectual property rights protection on bilateral flows of licensing revenues. We then empirically test our theoretical predictions using data on the cross-border flows of royalties and licence fees for 49 countries in the period 1995–2012. In addition to variables that capture the impact of shallow and deep regional trade agreements, we construct dummy variables that represent subcategories of IP rights-related provisions. Consistent with our theoretical predictions, we find that improved access to the destination market through a deep regional trade agreement and stronger IP rights protection through a regional trade agreement with legally enforceable IP rights and technology-related provisions increase bilateral flows of licensing revenues. Among IP rights-related provisions, the accession to or ratification of existing international IP agreements and the protection of trademarks, patents, or industrial designs are important for facilitating cross-border licensing.  相似文献
