Description

This segment introduces the film series and examines how two businesses can make decisions that help maximise profits as a result of using the mathematical technique of linear programming. Belgian chocolates are famous the world over. But there are many different kinds of chocolate that can be made. How can the producer pick the best combinations within the various constraints imposed on the business? We see how the mathematics of linear programming can help to give an insight into this question. (Duration 10 minutes 55 seconds). Part of a series of films from the METAL (Mathematics for Economics: enhancing Teaching and Learning) project that use a variety of industries as examples, to examine how businesses can maximise profits by using the mathematical technique of linear programming.

Description

The mathematics of Linear Programming is a useful tool. However, many relationships are not linear. How do we establish the price and quantity of a commodity if supply and demand functions are non-linear? Similarly, there may be non-linear relationships in the market for labour. And as we shall see, even where a demand curve is linear some of the important relationships that exist within such markets may not be linear. (Duration 10 minutes 27 seconds).

Now we extend the analysis of non-linear functions by beginning to illustrate the use of differential calculus. This is an essential tool for economists because in many areas of economics we are interested in the speed of change of functions as a means of dealing with economic problems. We will look at two simple examples here and develop further examples in our final film to extend our understanding of differential calculus. (Duration 6 minutes 20 seconds).

Slovenia recently joined the EU and is experiencing sustained growth in income. If it succeeds in growing at an annual rate of 4 per cent for the next two years average income will be rather higher. But how will that growth in income affect consumption and saving? We use Differential Calculus to find out. (Duration 5 minutes and 44 seconds).

Making rational decisions often means thinking about small changes, and many of them revolve around the idea of the margin - the marginal change. A useful way of analysing marginal changes is by differentiation. (Duration 7 minutes 21 seconds). Part of a series of films from the METAL (Mathematics for Economics: enhancing Teaching and Learning) project that show how partial differentiation and integration are used to gain constructive insights into economics as a discipline.

Up to a certain point, the higher the building, the lower the cost per floor. However at a certain point fixed costs rise dramatically to take into account the cost of deeper foundations and a stronger construction. In this film we introduce calculus to optimise spend and determine the appropriate number of floors to build. (Duration 5 minutes 18 seconds).
