The share of Chinese manufacturing imports in U.S. consumption has increased eight-fold between 1993 and 2011, from 1 to over 8 percent. While the literature has documented the pro-competitive price effect of the rising Chinese import competition on U.S. industries, I provide new empirical evidence for a quantitatively larger, indirect effect: for the average manufacturing industry, the increas...

The ground routing problem consists in scheduling the movements of aircraft on the ground between runways and parking positions while respecting operational and safety requirements in the most efficient way. We present a Mixed Integer Programming (MIP) formulation for routing aircraft along a predetermined path. This formulation is generalized to allow several possible paths. Our model takes in...

The purpose of this study was to establish and compare the number and the average annual rate of occupational accidents and traumatic injuries in two industrial plants (textile production, and manufacture of metal products) between 1993 and 2002 and to estimate the effects of a safety programme introduced in textile industry. Textile industry plant has been implementing a programme for the surv...

the corporate income tax rate plays a worthwhile role in developing fiscal and tax policies for companies, lawmakers and analysts. so, one of the most important issues in tax field, is to determine effective tax rates. the study and scientific calculations of the effective tax rates provide an enhanced tax justice and a careful study of tax pressure on taxpayers would be possible. the objective...

Economists are often interested in estimating averages with respect to distributions of unobservables, such as moments individual fixed-effects, or average partial effects discrete choice models. For quantities, we propose and study posterior (PAE), where the is computed conditional on sample, spirit empirical Bayes shrinkage methods. While usefulness for prediction well-understood, a justifica...
