This article examines the microeconometric evidence on the impact of government support for R&D and innovation. Our meta‐regression analysis uses a dataset of empirical evidence on the effects of government R&D policies on innovation and investigates the factors that may explain the differences in the estimated effects. The meta‐analysis is structured to include both the direct and indirect government support for R&D and innovation. The estimated results reveal the heterogeneity of empirical studies with respect to the type of incentive, data, and econometric methodology used. The results indicate that the output additionality effect is on average stronger for R&D tax incentives than subsidies. Studies that use the subsample of high technology sector show a stronger additionality effect of fiscal incentives on innovation. Moreover, small and medium enterprises have a stronger input additionality effect. The results also suggest that studies considered endogeneity issues have on average stronger additionality effect.  相似文献

ABSTRACT

Despite the extensive literature on distributive politics, there is still is a lack of a theory of how political and fiscal institutions interact to shape the pork barreling ability of national leaders in a federal parliamentary democracy. This article examines how the party system types (dominant party versus coalition system) and particular attributes of discretionary grants (providing credit claiming opportunity or facilitating side payments) influence opportunities for pork-barrel politics. This article proposes a situational theory of distributive politics that states that incentives for exclusive targeting of affiliated states in one-party dominant systems drive national ruling parties toward particularism while the shrinking opportunity to indulge in such a policy in multiparty coalition systems creates a universalization effect. The disaggregated analysis of discretionary grants using Indian data for 14 states for the one-party dominant period (1972–89) and the coalition era (1996–2012) confirms the theoretical expectations. Additionally, the exercise brings to the fore the fact that the shift from particularism to universalism occurs for schematic grants that provide credit claiming opportunity. The ad hoc grants that are like side payments remain subject to particularism.  相似文献

Inhalant abuse is a serious and ever-evolving problem for our society. Inhalants are abused more commonly by teenagers and adolescents. Inhalants such as glue, paint thinners, correction fluid, and nail paint remover are easily available in the market which makes them readily abused. Out of various methods of abuse, huffing (placing a piece of cloth soaked with inhalant is placed in the mouth), bagging (placing head in a polythene bag containing inhalant), and ballooning (balloons filled with inhalant are used for inhaling vapors through the mouth) are most common. Inhalant abuse results in multiple target organ dysfunction with neuritis and brain damage due to the dissolution of the myelin sheath. In acute poisoning cases, it might cause death due to asphyxia and sudden sniffing syndrome. In such cases, various articles containing traces of inhalants could be retrieved from the scene of incidence and to detect these traces become an important facet of the investigation. However, it might be difficult due to the rapid evaporation of inhalants and the formation of reaction product species. In the present study, an attempt has been made to study the effect of three substrates (balloon, cloth, polythene) on component profiles of four paint thinners and four nail paint removers. The study suggests that although some components are retained, there is the formation of a large number of reaction product species and these must be taken into consideration before furnishing the opinion. These reaction product species might also be inhalant specific which must be further explored.  相似文献

Investigating drowning-related deaths remains a significant problem for forensic personnel all over the world. The previously published decomposition scoring method like the total aquatic decomposition (TAD) score promises to estimate the correct post-mortem submersion interval (PMSI) in aquatic habitats through the assessment and calculation of the decomposition rate and accumulated degree days (ADD). The current study comprised of 53 drowned death cases belonging to various districts of Haryana from May 2016 to August 2017. The regression and Pearson's correlation indicated a significant correlation between the TAD scores and the actual ADD (calculated through water temperatures) (r2 = 0.917) and between the actual and the estimated ADDs (calculated through TAD scores used by Heaton et al. [21]) (r = 0.9585). The results indicated that the estimated ADD tends to over predict the PMSI compared to the actual ADD. It is further confirmed by paired t-test, which showed the mean of actual ADD (mean = 349) to be significantly lower than the mean of estimated ADD (mean = 663). Moreover, these methods will help forensic investigators and researchers formulate region-specific regression equations for PMSI estimation.  相似文献

In this essay—an earlier version of which was delivered as a lecture at a session cosponsored by Critical Asian Studies and the Alliance of Scholars Concerned about Korea (ASCK) at the annual conference of the Association for Asian Studies, San Diego, California, on 23 March 2013—the author argues the need to go beyond the current state of perilous confrontation and volatility on the Korean Peninsula and examine how and why the current division of the peninsula into North and South has evolved into a “division system.” The author contends that “civic participation” (broadly defined to include business entrepreneurs, corporations, NGOs, and private citizens) is necessary to deal with the durable enormity of the division system. He calls this body of nonstate actors the “third party” (the first two parties being those of North and South Korea). Going beyond strictly Korean affairs, this third party, the author concludes, can play a crucial role in creating a larger framework of East Asian cooperation and solidary.  相似文献

The aim of this paper is to study the effects of land tenure on agricultural production. This is an econometric study of production functions for the Ferozepur district of Punjab using Farm Management Studies data for 1968/69 and 1969/70. After a brief review of the theoretical literature, production functions are estimated to test for differences between small and large farms and for the relative inefficiency of tenants (on an inferior production function) relative to owners. We get slightly ambiguous results on the farm size issue but we find that the more land leased in by a farmer the less efficient he is.  相似文献
