This paper presents an updated estimation of the total factor productivity (TFP) of the U.S. economy following the two preceding empirical studies, Basu et al. (2001) and Burnside et al. (1995). Based on these two estimation approaches, both of which carefully handle the potential estimation bias stemming from cyclical utilization, we veriÞed that the TFP growth in the late 90s was, to some ext...

Technology and societal changes are moving the global market rapidly towards a new economic order rooted in e-commerce. Hence, assessing and monitoring the e-readiness of a nation has become an increasing challenge. This paper proposes a framework to evaluate the e-readiness of a nation based on eight factors: digital infrastructure, macro economy, ability to invest, knowledgeable citizens, com...

The characterisation of double central extensions in terms of commutators due to Janelidze (in the case of groups), Gran and Rossi (in the case of Mal’tsev varieties) and Rodelo and Van der Linden (in the case of semi-abelian categories) is shown to be still valid in the context of exact Mal’tsev categories.

We introduce the sharing economy as an IT-enabled phenomenon that is distinct from existing socioeconomic modes of interaction. While research on the consumer perspective is growing, studies examining the complementary organizational perspective seem to be lagging behind. Our study therefore aims to investigate the firm stance by analyzing how successful sharing economy organizations manage the...

What are the similarities and differences between crowdsourcing and sharing economy? What factors influence their use in developing countries? In light of recent developments in the use of IT-mediated technologies, such as crowdsourcing and the sharing economy, this manuscript examines their similarities and differences, and the challenges regarding their effective use in developing countries. ...

Many view the period after the Second Industrial Revolution as a paradigm of a transition to a new economy following a technological revolution, including the Information Technology Revolution. We build a quantitative model of diffusion and growth during transitions to evaluate that view. With a learning process quantified by data on the life cycle of US manufacturing plants, the model accounts...

We present a novel design for a peer-assisted content distribution system that addresses two key shortcomings of existing proposals. First, our system explicitly identifies the relative demand for files: users are rewarded for sharing more popular content. Second, our system efficiently utilizes network resources, by considering resource constraints explicitly when matching downloaders and uplo...

As the sharing economy has been increasing dramatically in the world, the mobile-hailed ridesharing companies like Uber and Lyft in the US, Didi Chuxing in China has begun to challenge traditional public transportation providers such as bus, subway or taxis. Ridesharing companies have shown their ability to provide the mobility services where public transit has failed. The human mobility demand...
