Measuring Sydney's Effective Job Density

Our nation's Gross Domestic Product (GDP) Increasing population Agglomeration Effective Job Density (EJD) EJD distribution across Sydney the metropolitan area Gross Domestic Product (GDP) in the past has been driven by more people entering the labour force. However, Australa's ageing population is likely to result Ina negative eftfect on the national GDP eits which fowns used of economic activity. Accordingly, increasing the level of agglomeration can boost labour productivity and GDP. EJD is used as a measurement of agglomeration, by looking at the relative size and spatial organisation of a city. ta frme feom ocing in veac with a hioher density %24 Vs Gbal Sdney Aing p on 150,000- Jobs at b 2-a Travel time ato b MAPPING SYDNEY'S EJD at a to b Hormsby 100.000 BaAtta Castle Hill C d and M re Prk oddion Brookvale Dee Why Renrith 48,700 Bcktogn 57,100 78,700 50,000 - Lhepet Macquacie Park eweed 77.200 Catswood Parfamatta 87,600 0% 20% 40% 80% 100% 157,400 Total land area by EJD (percentile) Sydaey Effective Job Density (EJD) Burwogd EJD has been calculated by SGS as a measure of underlying agglomeration. A simple measure, such as looking at the employment density of an area, does not effectively demonstrate the phenomenon of agglomeration. A firm in a BonfrJungtion 77,100 potentially cane oyment area but located on the edge of CBD could capture agglomeration benefits by being close to the CBD. Thus a measure of agglomeration must incorporate both proximity and the scale of the economic activity and, every small areas Graham, 2006 EJD is determined by assessing two key variables to achieve an index Bankstown EFEECTIVE ПОВ DENSITY Liverpool 53,200 or cumulative rank of an area where Var 1- Travel time from point a to point b Hurstville stvile ogarah (adjusted by mode of transport to destination b) Var 2- Number of jobs at b The EJD index at point a is the sum of EJD (a to b) + (a to ) + (a to d).

White collar dominant industries experience boosts to labour productivity from an Increase in ED whereas blue collar dominant employment eperiences the opposite. This is because blue collar employment (uch as manufacturing bansport and storagel prefers land in areas with good roed accessibility and kow underlying land values. So as EJD increases, underlying land values also increase and these industries often choose to relocate.
