Infrastructure and Growth

Abstract

Infrastructure plays a critical role in explaining the growth differentials between regions. The growth performances of Latin America are lagged behind East Asia and this fact is often attributed to the infrastructure gap between these regions. It is advised to Latin America to increase its infrastructure investments in order to record high growth rates. But as infrastructure is multidimensional, in which sector the investments should be channeled? This study tries to determine this with an empirical model. The empirical model in this study is a growth function and the infrastructure variables are added as an input to this function. Empirical results suggest that the long-run elasticity of transportation is higher than the long run elasticities of telecommunications and power. Thus, in order to catch-up East Asia quickly, Latin America should invest in transportation.

Tailor‐made ion‐imprinted polymer based on functionalized graphene oxide for the preconcentration and determination of trace copper in food samples

“…Additionally, the concentration of copper ions in GBW10055 detected by GFAAS was proximate value to the standard reference material (relative error <±1%). A comparison between the figures of merit of the method and some of the published methods for extraction and determination of copper ions are summarized in Table 3 [31][32][33][34][35][36][37]. Clearly, the adsorption capacity of our method is the highest among traditional adsorbents presented in the table, such as coprecipitating agent and silica, and the superiority here consists in establishment of cooperation between IIP and GO.…”
