Innovation, Di usion, and Trade
نویسندگان
چکیده
We explore the determinants of research specialization and examine the e ects of technology di usion and trade on the incentives for innovation. To some extent, di usion substitutes for trade. If trade costs are low relative to di erences in comparative advantage in doing research, rapid di usion implies specialization in research activity. Country size has an ambiguous e ect on specialization in research.

Activity-based costing diusion across organizations: an exploratory empirical analysis of Finnish ®rms
This study aims to explain what drives innovation diusion in management accounting during its various phases. Based on Abrahamson [Abrahamson, E. (1991). Managerial fads and fashions: the diusion and rejection of innovations. Academy of Management Review, 16, 586±612], four perspectives with potential to explain the diusion of accounting innovations are identi®ed: the ecient-choice, forced ...
متن کاملInstitutional Barriers to Technology Di¤usion in Rural Africa
Why is Africa poor? Conversely, what has sustained the immense economic growth we have seen in the U.K., the U.S., and other developed countries over the last couple of centuries? While there is no single answer to these questions, technical change looms large among possible explanations. From Solow’s seminal work on growth theory to the “new growth economics”, technical change is the engine of...
متن کاملBorrowing Constraints and Technology Di¤usion: Implications of Intra-Industry Trade (Job Market Paper)
This paper develops a theory of total factor productivity di¤erences in a framework of technology di¤usion. I show how in countries with tighter borrowing constraints, frontier technologies di¤use more slowly, and old outdated technologies continue to be used. I analyse how countries with di¤erent borrowing constraints specialise across new and old technologies through two forms of intra-indust...
متن کاملMultilevel Di usion Schemes for Repartitioning of Adaptive Meshes
For a large class of irregular grid applications, the structure of the mesh changes from one phase of the computation to the next. Eventually, as the graph evolves, the adapted mesh has to be repartitioned to ensure good load balance. If this new graph is partitioned from scratch, it will lead to an excessive migration of data among processors. In this paper, we present two new schemes for comp...

This study tests the importance of Ricardian technology di¤erences for international trade. Panel regressions nd technology growth increases manufacturing exports. To establish a causal relationship between technology and trade, instrumental-variables speci cations exploit uneven technology di¤usion from the US through ethnic scienti c networks. The instrumented elasticity of export growth to ...
