Do tougher environmental regulations cause firms to flee the country? Although several studies document the impact of environmental regulation on domestic production, the question of whether firms increase foreign manufacturing in response to new domestic regulation has remained unanswered. Consequently, our understanding of the efficacy of environmental policy is limited, as is our understandi...
Natural disasters have a statistically observable adverse impact on the macro-economy in the short-run. Not surprisingly, costlier events cause more pronounced slowdowns in production. Yet, interestingly, developing countries, and smaller economies, face much larger output declines following a disaster of similar relative magnitude than do developed countries or bigger economies. A close study ...
This paper seeks to isolate empirically the productivity effect of offshoring on establishment employment (e.g. Grossman and Rossi-Hansberg, 2008) from a direct employment effect via downsizing. The analysis is pursued for a representative sample of German establishments from 1998 to 2004, using a difference-in-differences matching approach. First, we find a positive employment effect from a qu...
This paper provides empirical evidence for the interaction between firm-level total factor productivity and trade liberalization as key determinants of firm-level job destruction caused by trade. We also test some key theoretical predictions from Melitz (2003), whose model is used to derive an explicit equation relating firm productivity and trade-induced labor layoff when a country liberalizes...
In the present study we examined the brain of fetal, newborn, and adult pigs raised for meat production. The fresh and formalin-fixed weights of the brain have been recorded and used, together with body weight, to calculate the Encephalization Quotient (EQ). The weight of the cerebellum has been used to calculate the Cerebellar Quotient (CQ). The results have been discussed together with analog...
The present study is to indicate that the comparison between sectoral production multipliers of an input-output (I/O) model and a social accounting matrix (SAM) framework is almost impossible without taking into account accounting balances and theoretical considerations. Theoretically, the I/O model provides the Leontief’s production function, on the basis of which sectoral output multiplier ca...
sugar beet as an industrial crop plays a main role in satisfying domestic demand of sugar. study on the production efficiency of sugar beet is important because this is a factor that influences production without additional cost. in this study, data envelopment analysis approach (dea), was implemented to calculate technical, administrative and scale efficiency of sugar beet production. also opt...
As perennial fruits, oranges rank only behind grapes in terms of total area planted, volume and value of production in Sonora (SARH). Prior to NAFTA only a small portion of Sonora's orange crop was exported to the U.S., and the remainder was consumed in the fresh domestic market (Donnadieu). Profits per carton sold in Mexico were greater than those earned by Sonoran exports to the United States...
We decompose labor productivity growth into components attributable to technological change, technological catch-up, foreign capital deepening, domestic capital deepening, and human capital accumulation, thus separating the effects of foreign and domestic capital deepening on productivity growth and convergence. We apply nonparametric production-frontier methods to a worldwide 1980-2005 panel a...
