3  Factors that cause a producer’s average cost per unit to fall as output rises. Factors may be:  Internal - cost reduction due to technological and management factors  External - cost reduction due to the effect of technology in an industry  Ford Motor Company was able to mass produce affordable cars in minimal time because of economies of scale. 3 Copyright © Texas Education Agency, 2011. All rights reserved.

4  Increase in long-term average cost of production as the scale of operations increases beyond a certain level. May be caused by:  over-crowding where men and machines get in each other's way,  greater wastage due to lack of coordination  a mismatch between the optimum outputs of different operations 4 Copyright © Texas Education Agency, 2011.

5  A graph of the costs of production as a function of total quantity produced.  Used to find the optimal point of production, where companies make the most profits. 5 Copyright © Texas Education Agency, 2011. All rights reserved.

6  Captures the relation between cost per unit and the level of output, ceteris paribus.  Firms organize their factors of production in such a way that the average cost of production is at lowest point and intersects Marginal Cost. 6 Copyright © Texas Education Agency, 2011. All rights reserved.

7  Depicts what the minimum per-unit cost of producing a certain number of units would be if all productive inputs could be varied.  U-shaped  Reflects economies of scale when negatively-sloped and diseconomies of scale when positively sloped. 7 Copyright © Texas Education Agency, 2011.

9  Production process with neither economies nor diseconomies of scale.  The output of the process increases or decreases simultaneously and in step with increase or decrease in the inputs.  A plant with constant returns to scale is equally efficient in producing small batches as it is in producing large batches. 9 Copyright © Texas Education Agency, 2011. All rights reserved.

10  Describe economies of scale.  Compare short-run and long-run curves.  What is meant by diseconomies of scale?  Describe constant return of scale.  What is the difference between diminishing returns and economies of scales? 10 Copyright © Texas Education Agency, 2011. All rights reserved.
