1 UEMC2513 Building Economics and Finance Introduction To Urban Land Economics

2 © Chia Fah Choy 2005 Learning Objectives After studying this topic you will: be able to explain the concept of ‘economic rent’ Show how a demand curve of land can be determined Explain and illustrate how the interaction of demand and supply will lead to an equilibrium market price or rent Explain the economic rationale for intensity of site use Explain how the timing of redevelopment is an economic decision

3 © Chia Fah Choy 2005 Land Undeveloped land, or ‘pure’ land, refers solely to natural resources and space. Land as a whole i.e. the earth’s land surface – can be regarded as being fixed in supply. Increasing such land by reclamation from the sea shall be view as an additional to capital goods rather than to land.

5 © Chia Fah Choy 2005 Price perform the vital function of rationing scarce supply among competing uses. Supply of land can never be regarded as fixed from the viewpoint of any one use. The productivity of land can usually be increased in response to additional demand by using it more intensively by the addition of capital. Land as whole are entirely demand- determined – a tax on pure land has no disincentive effect on the supply of land The Pricing of Land

6 © Chia Fah Choy 2005 The Pricing of Land Unless all forms of land use are taxed equally, the pattern of land use will be distorted Whether such distortion is on balance good or bad can only be decided by: –A comparison with the inevitable distortions produced by alternative taxes –Its connection with spillover benefits and costs –One’s political views Cost of production include normal profit – what is necessary to keep the entrepreneur in the current line of production

7 © Chia Fah Choy 2005 Commercial rent is simply a periodic payment for the hire of land. Normally, there is competition for land between the different potential users. The rent of land, therefore, is determined in the absence of any government interference, by the interaction of demand and supply. The Commercial Rent of Land

8 © Chia Fah Choy 2005 The Demand of Land Assumptions: The land under discussion is homogenous Buyers are only interested in maximising private utility or money returns Conditions of demand and supply do not change A long-period situation prevails The output at which profits are maximised is known

9 © Chia Fah Choy 2005 The Demand of Land The demand for land as a factor of production is a derived demand It has to be combined with other factors, labor and capital, to produce the goods that are wanted The quantity of land which a firm demands depends upon: –its productivity –the price relative to other factors –the price of the final product

10 © Chia Fah Choy 2005 The Demand of Land Thee main problems have to be answered: How does a change in the price of land relative to other factors affect the demand for land? How will a change in the productivity of land in a particular use affect demand? How will a change in the price of the product affect the demand for land in that use?

16 © Chia Fah Choy 2005 The Demand of Land A fall in the price of a factor will lead to an extension of demand (the demand curves slopes downwards) An increase in productivity or an increase in the price of the product will lead to an increase in demand for the factor (the demand curve moves to the right)

Competition among developers ensures that any supernormal development profit tends to accrue to sellers of building sites in the form of higher land prices

The alternative use with greater productivity would shown by the higher MRP’ curve Competition will ensures that the site is developed upwards to the point where MR=MC where A’BC’ is maximum A higher building and a higher site price will result from a rise in the MRP of capital The higher the land price, the more intensive use of the land is required. High land prices have caused high buildings
