This research aimed to determine the economic scales of production and
different product values, and the difference between the true sizes and its
parallel economic areas in the midregion of Jordan. The econometrics analysis
was used for the cost
functions of sheep, goats, and cows production in
midregion of Jordan. The data were analyzed by linear regression using
suitable economic models.
Total production functions of sheep were determined, and the average
productivity was derived to determine the economic scales in order to minimize
the average productivity cost of sheep, goats and cows. For the sheep, the
product value was about JD 16649.59 for 419 sheep, with average cost of one
JD is 0.522 JD. Marginal cost function was derived from the total production
cost function, with the equality marginal cost function to parallel price in order
to reach the scale of maximize profit. The production value was 18251.49 JD
for 460 sheep and average JD cost of 0.56. The present productivity scale was
157sheep which was 262 sheep lower than the productivity scales for economic
efficiency and 303 sheep lower than that for maximize profit.

The research aims to estimate the marketing efficiency of rain-fed cumin crop in Malikya
area (Al-Hassaka governorate),this in order to reach the estimation of the total costs of marketing
functions, medium and marginal costs, and estimate the econ
omic volumes of marketed quantities
of cumin. This study main problem lies in the search for high marketing costs of latency. Find
carried out based on cross-sectional data, that were collected from a random sample of some cumin
farmers and traders in Malikya area (88 farmers from 24 villages, and 12 trader cumin), And
adopted in the implementation of research analysis method rebound with a single equation, to
explain the relationship between marketed quantities of cumin as an independent variable, and the
value of its marketing costs as the dependent variable. Results of the analysis showed that the value
of the coefficient of determination (R Square) amounted to 0.841, and this means that the quantity
of marketed cumin explain 84.1% of the changes in the marketing costs of cumin, The results of
econometric analysis also showed the presence of deviations between marketed quantities of
cumin, and the size of optimal marketed quantities due to higher overall marketing costs, medium
costs, and marginal costs for the quantities marketed, means increased current cost of marketing for
one kilogram of cumin, from those achieved for marketing efficient g by (2.1) SP / kg,
furthermore, the application results of equations, measuring marketing efficiency (which relied on
total production costs, the current cost of marketing the crop cumin, and the selling price per
kilogram of it) showed that, the value of marketing efficiency amounted to about 88.29% and
50.53% depending on the indices marketing efficiency (equations 1 and 2 ) respectively , While the
value of marketing efficiency (which relied on total production costs, and the optimum marking
cost of the cumin, and the selling price per kilogram of it), about 90.54% and 52.73% depending on
the indices marketing efficiency (equations 1 and 2), respectively, The research found a set of
recommendations, such as establishing a marketing institution that oversees the operations of sale
and marketing of medicinal and aromatic plants Group, and market surveillance in order to prevent
monopoly, and improve the performance of marketing functions that traders provide when
marketing of medicinal and aromatic products that, in order to reduce the costs of marketing, and
delivery to consumers at the best prices.
On the fact that the production process held by a cemint'
factory at tartous region province , cause air , land , pollution that
might be reflected in bad health of people those either work at
factory or live nearby.
Therefor the present studies
take into its considerations the
new alternatives to lower such pollution level so as the production
cost therefor higher profits will be gained as a result the higher
welfare is.
The present research aimed at calculating the optimum size
of production so reaching the minimum point at production cost
curve. The profit function in the short run was used , the results
showed that the optimum size of phosphate' factory product
ion
amounted to about 27.5 thousands ton which accompanied with
both minimum cost and higher profit.
