The spatial patterns of poverty in India are of considerable importance in themselves and for development theory and practice. This article examines the determinants of rural poverty in India using spatial econometric methods. It finds that while agricultural growth is the key determinant of rural poverty declines, there is significant spatial dependence in the growth rates of agricultural output. Irrigation is the primary driver of agricultural growth, and spatial variations in irrigation development seem to be associated with agro‐ecological conditions which may be vastly different within Indian states, parts of which may be similar to those prevailing in geographically contiguous states. Poverty reduction strategies need to be designed in the light of spatial factors and using spatial methods.  相似文献

Over the past three decades, China has experienced significant internal migration. However, migrants are often socially segregated and discriminated against in their destination cities in China. This paper uses a large representative survey to investigate whether interpersonal contact between urban locals and migrants improves urban locals’ attitudes towards migrants. The novel part of this paper is to examine the effect of different contact experiences on multiple dimensions of attitudes. The results show distinct patterns between the effects of non‐intimate and intimate contact experiences. All the OLS results, IV results and IV results together with Lewbel's ( 2012 ) heteroscedasticity identification approach suggest that non‐intimate contact experience only significantly improves willingness to engage in non‐intimate interactions, and the magnitude of the effect reduces as the intimacy level of the intended interaction increases. On the contrary, intimate contact experience significantly improves willingness to engage in both non‐intimate and intimate interactions.  相似文献

To foster ‘creative destruction,’ entrants must survive the turbulent conditions they face in their first crucial years in the industry. We investigate how the external knowledge milieu of an entrant, conceptualized as its innovative environment, causes systematic variation in survival patterns. We test our model from 3,431 firms in 33 industries over 80 years. We depict the innovative environment along two knowledge‐related dimensions, namely technology regime and technology intensity. While the aligned state of the innovative environment, where product innovation exists in tandem with abundant innovation opportunities, promotes entrant survival, we find that this beneficial effect is more pronounced for small entrants due to a possible mitigation of scale disadvantages.

传统财政本质理论尽管有值得借鉴之处,但存在明显缺陷。界定财政本质必须分析制约财政发展演变过程的内在矛盾,并说明财政的起源及各个历史发展阶段。财政的本质是协调私人需要和公共需要矛盾的手段或方式。如此界定财政本质具有重要意义。  相似文献

It is shown that for a small open economy the welfare effects of a tariff on the import of the brands of a differentiated good depends crucially on the pattern of trade. The literature has shown that welfare rises when the domestic brands are nontraded. But when the domestic brands are traded, the imposition of a tariff lowers welfare by shifting demand towards the nontraded homogeneous good which causes exit from the differentiated goods industry.  相似文献

In quality-differentiated audit markets with client-firms of unknown types, insider-managers of client firms strategically select auditors who respond to legal liabilities to decide their care level. In this signaling game, uninformed-investors use the audit report and the auditors' identity for firm valuation. The analysis shows that increased legal liability increases the auditor's effort and audit accuracy but reduces the demand for high quality auditing because, apart from the increased audit costs, the adverse selection benefit of the worse type reduces with increased accuracy. Furthermore, alternative legal regimes and damage allocation rules alter informational efficiency of the financial market.  相似文献
