An identity links the rate of economic growth, the speed of poverty reduction and changes in the distribution of income during some time period in a given country. A few authors used that identity to understand the causes for observed changes in poverty and to identify the exact role of economic growth in poverty reduction. Yet, many empirical cross-country studies of the relationship between g...

The G31.41+0.31 (G31) hot molecular core (HMC) is a high-mass protocluster showing accelerated infall and rotational spin-up that well studied at high-angular resolution. To complement the accurate view of small scale in G31, we have traced kinematics large-scale material by carrying out N$_2$H$^+$\,(1--0) observations with IRAM 30m telescope an area $\sim$6$\times6$\,arcmin$^2$ around HMC. N$_...

This article adds technology choice to a free-entry Cournot model with linear demand and constant marginal costs. Firms can choose from a discrete set of technologies. This simple framework yields non-existence of equilibrium, existence of multiple equilibria and equilibria in which ex-ante identical ̄rms choose di®erent technologies as possible outcomes. I provide a full characterization of th...

Abstract Background Domestication usually has negative effects on insect performance, especially when they are reared continuously for many generations. Rejuvenation can reduce the of domestication in parasitoid, Trichogramma brassicae Bezdenko (Hymenoptera: Trichogrammatidae) 30 generations (G) Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae). Life table and parasitism parameters prim...
