Sommario/riassunto |
|
Testing for economic convergence across countries has been a central issue in the literature of economic growth and development. This book introduces a modern framework to study the cross-country convergence dynamics in labor productivity and its proximate sources: capital accumulation and aggregate efficiency. In particular, recent convergence dynamics of developed as well as developing countries are evaluated through the lens of a non-linear dynamic factor model and a clustering algorithm for panel data. This framework allows us to examine key economic phenomena such as technological heterogeneity and multiple equilibria. In this context, the book provides a succinct review of the recent club convergence literature, a comparative view of developed and developing countries, and a tutorial on how to implement the club convergence framework in the statistical software Stata. |

Sommario/riassunto |
|
This book gives an almost forgotten history concerning civilian university scientists, who carried out research on defense against poison gases in some unusual places during World War II. Most of these were graduate students, working under the direction of professors at the California Institute of Technology (Cal tech) and the University of California (Berkeley). The first job on these projects was to make major improvements on gas masks. Later, most activities were done outdoors to assess the effects of terrain and meteorological conditions on the travel and dissipation of toxic gas clouds. Action took |
