GreenApps: A Platform for Cellular Edge Applications

Ahmad, T., Reed-Sanchez, E., Zarinni, F., Afutu, A., Adjaho, K., Nyarko, Y., & Subramanian, L. (2018, June). GreenApps: A Platform For Cellular Edge Applications. In Proceedings of the 1st ACM SIGCAS Conference on Computing and Sustainable Societies, (p. 45). ACM.

This paper presents the design, implementation and deployment of GreenApps, a ground-up platform that enables off-grid, near off-line and highly available cellular applications in rural contexts. The GreenApps platform has been deployed in two rural regions in Kumawu, Ghana and Pearl Lagoon, Nicaragua and supports different community-centric applications.

Computing the Rate of Disappearance of Cropland Using Satellite Images

Chakraborty, S., Dalton, S., Nyarko, Y., and Subramanian, L., (2012). Computing the Rate of Disappearance of Cropland Using Satellite Images. In Proceedings of the 3rd International Conference on Computational Sustainability, Denmark.

Apart from human-led development, changing climate is also leading towards a change in the land pattern. In both scenarios, a solution to the problem can be a monitoring tool, which can identify the change in land pattern over the years. In this paper, we present a tool that can monitor this change through satellite images.

Is the Brain Drain Good for Africa?

Nyarko, Y., & Easterly, W. “Is the Brain Drain Good for Africa?” Skilled Immigration Today: Prospects, Problems, and Policies., edited by Bhagwati et al., Oxford University Press, 2009.

We build upon recent literature to do several exercises to assess benefits and costs of the brain drain to Africa. Contrary to a lot of the worries expressed in the media and in aid agencies, the brain drain is probably a net benefit to the source countries…

The Bayesian Foundations of Learning by Doing

Jovanovic, B., & Nyarko, Y. (1996). The Bayesian Foundations of Learning by Doing. Econometrica, 64(6), 1299-1310.

Research and Productivity

Jovanovic, B., & Nyarko, Y. “Research and Productivity.” Creation and Transfer of Knowledge, edited by Navaretti et al., Springer, Berlin, Heidelberg, 1995.

We model research as a signal on an unknown parameter of a technology. We distinguish applied from basic research and show that firms in the same industry can optimally choose different research portfolios, and that basic research van seem to have a higher rate of return than applied research, even though it really doesn’t - essentially, firms on a “fast track” upgrading policy opt for basic research but fast and slow-track upgrading policies can coexist in a long-run equilibrium.

A Bayesian Learning Model Fitted to a Variety of Empirical Learning Curves

Jovanovic, B., & Nyarko, Y. (1995). A Bayesian Learning Model Fitted to a Variety of Empirical Learning Curves. Brookings Papers on Economic Activity. Microeconomics, (1), 247-305.

Where does technological progress come from and what determines its rate of advance? In answering these questions, it is useful to decompose technological progress into the invention of new techniques and products and the improvement of existing ones.

The Transfer of Human Capital

Jovanovic, B., & Nyarko, Y. (1995). The Transfer of Human Capital. Journal of Economic Dynamics and Control, 19(5-7), 1033-1064.

Most of our productive knowledge was handed down to us by previous generations. The transfer of knowledge from the old to the young is therefore a cornerstone of productivity growth.
