The exchange rate unification is one of the most important instruments of economic adjustment, which is used in many countries. This paper shows the effects of the exchange rate unification on price level (inflation), gross domestic production (GDP), non-oil exports, private conception, government expenditure and stock of money. The data, is used related to the period 1959-2000. To analyze the ...

This paper provides estimation method to measure technical efficiency of production units and the speed of adjustment of output, both varying with time, from a dynamic stochastic production frontier that incorporates the sluggish adjustment of inputs. Using a panel dataset on private manufacturing establishments in Egypt, I find that the speed of adjustment of output is lower than unity in ever...

BACKGROUND Racing drivers require multifaceted cognitive and physical abilities in a multitasking situation. A knowledge of their physical capacities may help to improve fitness and performance. OBJECTIVE To compare reaction time, stability performance capacity, and strength performance capacity of élite racing drivers with those of age-matched, physically active controls. METHODS Eight éli...

Background: According to the results of epidemiological studies, human beings from various races, colors, cultural, educational and economic backgrounds are affected by cancer worldwide, thereby encouraging researchers to conduct extensive studies in this regard. We aimed to compare the components of quality of life and adjustment in both cancer-stricken and healthy children. Materials and Meth...

productivity shocks are one of the most important factors that influence the firms ‘ decisions on he optimal consumption of production inputs. unobservable productivity shocks create selection and simultaneity problems causing biased estimates of production function by ordinary least squares. however, to estimate coefficients associated with production function by levinsohn and petrin technique...

The paper examines the impact of selected structural adjustment policies on food production in Zambia. Using a four year panel of post-harvest data, a system of six crops, two variable inputs and three fixed inputs is estimated. The resulting supply responses suggest a negatively slopped supply curve for sorghum and millet and this has been attributed to the presence of credit constraints. Simu...

One layer of global geographic database Reference3D® is an image mosaic (5m resolution) made exclusively from panchromatic SPOT5-HRS images. In order to improve Reference3D® production line, in particular SPOT5 HRS images mosaicking step, a new strategy of radiometric block adjustment of satellite images was developed, implemented and tested at French mapping agency IGN. By analogy with “geomet...
