How does rural-urban migration shape urban production in developing countries? We use longitudinal data on Chinese manufacturing firms between 2000 and 2006, exploit exogenous variation induced by agricultural income shocks for identification. find that, when immigration increases, becomes more labor intensive productivity declines. investigate the reorganization of using patent applications pr...

This note generalizes analytical relationships among activity variables of DEA models previously derived by Boussemart, Briec and Leleu (2007). We relax the asumption of constant returns to scale by showing that the key results hold under a weaker asumption of homogeneity. We use the notion of α -returns to scale to extend the analysis to strictly increasing and decreasing returns, covering now...

participants will be introduced to the risks associated with excessive early childhood televiewing and develop an understanding of the current recommended guidelines for children’s television exposure. my research agenda in montreal (canada) addresses modifiable factors in early childhood that influence human development. from birth through the preschool years, exponential brain maturation is c...

Is market-based or bank-based financial system better for fostering technological innovation as an engine of growth? I present evidence that bank-based systems promote rapid technological progress in those industrial sectors that depend heavily on external finance for funding innovation by facilitating credit access to younger firms. On the other hand, I also find evidence of a general positive...

The evolution of economies during the major portion of human history was marked by Malthusian Stagnation. The transition from an epoch of stagnation to a state of sustained economic growth has shaped the contemporary world economy and has led to the Great Divergence in income per capita across the globe in the past two centuries. This entry examines the process of development over the course of...

In a multi-industry growth model, firms require external funds to conduct productivityenhancing R&D, and are limited by financing constraints. The cost of research differs across industries, so financing constraints hinder productivity growth in some industries more than in others. Equilibrium industry dynamics map into a differences-indifferences regression specification where industry growth ...

The Great Leap Forward disaster, characterized by a collapse in grain production and a widespread famine in China between 1959 and 1961, is found attributable to a systemic failure in central planning. Wishfully expecting a great leap in agricultural productivity from collectivization, the Chinese government accelerated its aggressive industrialization timetable. Grain output fell sharply as th...

The impact of weaning age and/or supplemental liquid feed in the farrowing pen on pre- and post-weaning intake was investigated. systems consisted a milk replacer from day 2, changed to cereal-based 12 days after birth. By continuing with same post-weaning, but dry form, we hypothesised that change would be less abrupt increase post-weaning. study 24 sows their litters 2 × factorial design. des...
