This paper investigates the relationship between telecommunications infrastructure competition, investment and productivity. Using econometric modelling and input-output economics, the analysis examines and measures the extent to which telecommunications has contributed to national and sectoral productivity performance. The main findings from this paper suggests that most industries have benefi...

We study the importance of input-output (IO) linkages and sectoral productivity (TFP) in determining cross-country income differences. find that while highly connected sectors are more productive than typical sector poor countries, opposite is true rich ones. To assess quantitative role TFP differences differences, we decompose variation using a multisector general equilibrium model. IO substan...

Toxin production in Clostridium perfringens is controlled by the VirSR two-component signal transduction system, which comprises the VirS sensor histidine kinase and the VirR response regulator. Other studies have concentrated on the elucidation of the genes controlled by this network; there is little information regarding the phosphorelay cascade that is the hallmark of such regulatory systems...

We model the world economy as one system of endogenous input-output relationships subject to frictions and study how world’s structure GDP change due changes in frictions. derive a sufficient statistic identify from observed matrix, which we fully match for year 2011. show internal impact whole that they have much larger effect on than external also use our approach role during Great Recession ...

The demand for durable goods is more cyclical than that for nondurable goods and services. Consequently, the cash flow and stock returns of durable-good producers are exposed to higher systematic risk. Using the benchmark input-output accounts of the National Income and Product Accounts, we construct portfolios of durablegood, nondurable-good, and service producers. In the cross-section, an inv...

Ragnar Frisch on various occasions claimed that he had invented input-output analysis in a 1934 paper titled “Circulation planning”. Although prominently published in Econometrica, Frisch’s contribution has hardly been discussed in the input-output literature. Frisch’s paper was an attempt to explain the incapsulating phenomena of economic depressions and thus arose from a different motivation ...
