Effectiveness of the Special Economic Zone policy over the Export Processing Zone structure in India: trade performance at the aggregate level
Empirical evidence on the effectiveness of recent India's Special Economic Zone (SEZ) policy over Export Processing Zone structure is analysed in this article by aggregating data of seven conventional SEZs from 1986–1987 to 2007–2008. The study reveals that introduction of SEZs in place of its predecessor, the Export Processing Zone, is having a significant and positive impact on its trade performance at the aggregate level. However, in terms of contribution to national trade, the Indian SEZs are lagging way behind the expectations of policymakers. Furthermore, the SEZ policy does not seem to be successful in diversifying the exports basket, which in turn has affected the direction of exports by the SEZs. Moreover, these zones were found to be highly susceptible to external shocks. Thus, we strongly argue in favour of a care in deciding the sectoral choice of SEZs and careful scrutiny of its approval across major Indian states.
Did the metamorphosis from Export Processing Zones to Special Economic Zones improve the efficiency of trade enclaves in India?
In this paper, the efficiency of seven conventional Special Economic Zones in India is analyzed, by adopting a stochastic production frontier technique, for the period between 1986–1987 and 2007–2008.Results indicate that although the efficiency scores of these enclaves have improved over the years, specifically with the introduction of the SEZ policy (2000–2001), it is far below the threshold level as identified in the literature. Besides, one can also observe a discrepancy emerging between better export earning zones and efficient zones. On the determinants side, policy intervention and large geographical area, accompanied by clustering of units, are found to have impacted the efficiency scores of these enclaves positively.
The development of biological systematics : Antoine-Laurent de Jussieu, nature, and the natural system
A reevaluation of the history of biological systematics that discusses the formative years of the so-called natural system of classification in the eighteenth and nineteenth centuries. Shows how classifications came to be treated as conventions; systematic practice was not linked to clearly articulated theory; there was general confusion over the "shape" of nature; botany, elements of natural history, and systematics were conflated; and systematics took a position near the bottom of the hierarchy of sciences.
