Why do some countries economies grow faster ?

MIT News on the economic growth theories of César Hidalgo and Ricardo Hausman,they contend amongst other things the importance of dense variegated clusters:
“Countries get trapped because they are in a sparse part of the product space.”-Ricardo Hausman
The standard theoretical framework for development economics was established more than 50 years ago by the MIT economist Robert Solow, who developed a mathematical model that predicts countries’ economic growth on the basis of labor and capital (the tools of production); subsequent work expanded the model to include factors such as land and human capital (expert knowledge). The model proved highly influential, ultimately earning Solow the 1987 Nobel Prize in economics.
Hidalgo argues, by lumping together a huge variety of resources under the general heading “capital,” it can obscure distinctions that are crucial to an accurate understanding of countries’ economies. In a series of papers cowritten with Ricardo Hausmann, director of the Center for International Development at Harvard’s Kennedy School of Government, Hidalgo has argued that, indeed, the best predictor of a country’s future economic health is not the magnitude but the diversity of its production capacity.
