As we celebrate the coming year with hope and optimism for change and progress, let us look at the video clip below to remind us, despite the apparent global convulsion due to the flawed economic paradigm of neoliberalism, how much the world has progressed across centuries. The presentation by Hans Rosling, a Swedish medical doctor, academic, statistician and public speaker, can serve as inspiration of how much innovation and technological change can push nations from the brink of poverty towards modernity.
The trajectory of growth (and how they sort of "converge") reminds me of the Solow–Swan model (also known as the exogenous growth model and the neoclassical growth model) - a model of a long-run economic growth. The model was developed independently by Robert Solow and T. Swan from the earlier Harrod-Domar model used to explain an economy's growth rate in terms of the level of saving and productivity of capital.
