We provide a simple framework for interpreting instrumental variable regressions when there is a gap in time between the impact of the instrument and the measurement of the endogenous variable, highlighting a particular violation of the exclusion restriction that can arise in this setting. In...

The study measures farm level technical efficiency among paddy farmers of Hailakandi district of Assam on the basis of farm level primary data of 265 cultivators for the peak cropping season of 2009-10. A translog stochastic production frontier is estimated and selected non-input factors are...

Purpose - Our generation is witnessing the greatest demographic transition and Africa is at the heart of it. There is mounting concern over corresponding rising unemployment and depleting per capita income. I examine the issues in this paper from a long-run perspective by assessing the...

The role of Africa in world demographic change is primary and consequences on future investment dynamics could provide some insight on how unemployment, economic migration and other issues resulting there-from could be addressed. Using Johansen and Granger-causality models on data from 1977 to...

An important question is whether underdeveloped countries will converge to the per-capita income level of developed countries. Economists have used the disequilibrium adjustment property of growth models to justify the view that convergence should occur. Unfortunately, the empirical literature...
