Game theory<br />
Game theory, first developed by von Neumann (1903-57), is the study <strong>of</strong><br />
strategic decision making by more than one person. A classic application<br />
<strong>of</strong> game theory is in the study <strong>of</strong> oligopolies or markets in which there are<br />
a few firms, each <strong>of</strong> which has to consider the response <strong>of</strong> others before<br />
acting. In such a market, before a firm raises or drops its prices, it has to<br />
consider whether the others will follow or take no action. Using game<br />
theory, it can be shown that in such a market, the oligopolists are likely to<br />
maintain price stability (von Neumann J, Morgenstern O (1944) The theory<br />
<strong>of</strong> games and economic behaviour. John Wiley, New York. Gibbons R (1992)<br />
A primer in game theory. Harvester Wheatsheaf, Hertfordshire).<br />

GDP deflator<br />
The gross domestic product (GDP) deflator is a number which shows the<br />
GDP in constant prices. It is derived by dividing the GDP in current prices<br />
by the GDP in constant prices. When presenting the GDP deflator for a<br />
number <strong>of</strong> years in the form <strong>of</strong> a series, scaling is used. A given year is<br />
used as the reference year and given a value <strong>of</strong> 100. For example, in the<br />
1994 US Economic Report to the President, the GDP deflator for 1987 was<br />
assigned a value <strong>of</strong> 100. The deflators for 1985,1986,1987,1988,1989 and<br />
1990 were given as 94.4, 96.6, 100, 103.9, 108.5 and 113.3 respectively.<br />
Therefore, given the deflator for a given year and the GDP for that year, the<br />
GDP can be expressed in 1987 dollars.<br />
General Household Survey<br />
The General Household Survey (GHS) is an annual survey undertaken by<br />
the UK Office for National Statistics (ONS) to provide data on health,<br />
population characteristics, education and economic activity. The need for<br />
the GHS is being reviewed by the ONS.
