Technology adoption and factor proportions in open economies : theory and evidence from the global computer industry [PDF]
Theories of international trade assume that all countries use similar and exogenous technologies in the production of any good. This paper relaxes this assumption. The marriage of literatures on biased technical change and trade yields a tractable theory,

Abstract Stress on the agro-qualitative traits of soybean is oftenly observed in maize-soybean intercropping system due to the expected shadding effect of the companion crop. Canopy manipulation of maize would pave the role to improve the productivity and land equivalent ratio of maize-soybean intercropping system.

American Journal of Agricultural Economics, EarlyView.Abstract This paper derives a firm‐level threshold, the Herfindahl Neutral Point, from the standard concentration index used in merger review. At this threshold, a marginal expansion leaves the index unchanged. Firms below the threshold reduce concentration when they expand; firms above it increase concentration.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Applications in Plant Sciences, EarlyView.Abstract Premise Applied ecology can significantly influence policy decisions on environmental issues. Therefore, research in this field should be as transparent and reproducible as possible. Existing expertise from a broad range of disciplines should also be integrated into ecological research to allow researchers to maximize understanding of complex ...
