The city as a labour market: 2


In my last blog, I looked at the types of jobs being created in Auckland, over the period 2001 to 2016. Of note has been the big increase in the number of jobs in the professional, science and technical services sector (sector M in the ANZSIC). In this blog I want to look more closely at this sector.

Maybe one of the roles of planning is to positively support the growth of areas of employment where the city has a comparative advantage.

The relative importance of the sector for Auckland, compared to the national economy, can be assessed in simple terms by calculating a location quotient. Infometrics, in their Auckland Economic Profile web page (1) note that:
A high concentration of certain industries in an area can be indicative of the area having a comparative advantage in these industries. This comparative advantage may be a result of the area’s natural endowments, location, skill profile, or other reasons.
Location quotients (are used) to identify what industries an area may have a comparative advantage in. An area has a location quotient larger than one when the share of that industry in the area’s economy is greater than the share of the same industry in the national economy.
Industry sectors in Auckland that have a location quotient greater than 1.1 are as follows, based on 2016 data.
Figure 1: Location Quotients over 1.1, Auckland Region, 2016


As a comparison, the location quotient for sector “C” - manufacturing - is 0.97.
The location quotients suggest that Auckland’s economy, beyond those parts of the economy that serves the resident population and/or is basically the same as the rest of the country, really falls into three groups:
  • Warehousing and distribution
  • Financial, insurance and banking
  • Professional services.
A more fine grained analysis of industry sectors will reveal further clusters. For example, there will be some types of manufacturing activities that are concentrated in the city.
The M sector is relatively important. It has a location quotient of 1.34, which is quite high.  
This is, however, a static picture. Comparing location quotients in 2001 and 2016 shows some changes in relative concentration. The table below lists the location quotients for 2001 and 2016, as well as the change in the number of people employed in the sector between these dates, for the Auckland Region.  
Table 1: Location Quotients  2001 and 2016, and employment change.

 M Professional, Scientific and Technical

So over the period 2001 to 2016, Auckland’s relative strength in the wholesale trade sector dropped a bit, but employment increased. On the other hand, the region’s strong advantage in information, media and telecommunications increased, but employment actually dropped in this category.
The professional, scientific and technical sector increased in relative importance and increased substantially in employment, as did the financial and insurance sectors.
Sounds impressive, but in terms of incomes and wealth generated by the “M” sector, the sector tends to be at the lower end of the higher paying jobs. Looking at contribution to GDP, the following data is provided by Infometrics. It is the average GDP generated per worker in the Auckland Region, for 2016, by industry sector.
Figure 2: GDP per employee, by sector, Auckland Region 2016
The productivity of those in the rental, hiring and real estate sector (at over $300,000 per worker) is a bit hard to understand. As noted the FIRE sector (finance, insurance, information, real estate) tend to be sectors with the higher salaries and the biggest contribution to GDP per worker, but haven’t grown so much over the past few years.
The general picture is of Auckland’s labour market growing and changing over time. The growth of the professional, scientific and technical services sector has probably helped to diversify the economy somewhat, which is positive. But it has mostly been a picture of the expansion of the ‘base’ of the economy, with the relative decline in the banking, finance and insurance sectors. The M sector has risen in importance but this sector is not a big contributor to regional GDP on a per head basis.
Next up, where are the jobs in the ‘M’ sector located?
Starting at the Local Board level, the concentration of jobs in the sector in the inner Isthmus area (Waitemata Local Board)  is very strong. See the following graph.  
Figure 3: Employment location, sector M, 2016, by Local Board.
Taking a closer look at the Census Area Unit level, the following maps the number of people employed in the sector, again for 2016, by workplace location. There is a very strong clustering in the inner city area, with smaller outliers in Takapuna and Ellerslie. The Upper Harbour Local Board area has more people employed in the M sector, than Devonport-Takapuna, but in the Upper Harbour area, they are spread over a wider area.  
Figure 4: Location of sector M employment, by census area unit, 2016




In terms of the other-side-of-the-coin, where do the people who work in the M sector live?
The following is a map of the percentage of people in full time or part time jobs employed in the M sector, for 2013 (the last census), by total number of people in work, by census area unit, by home location.
Figure 5: Location of home residence, people employed in sector M, 2013. Percentage of total workforce in Area Unit.
As about 11% of regional employment is in the M sector, then more than 10% of people who live in a census area unit and who are employed in the sector shows a relative concentration in terms of home location.
The map shows a very strong concentration of people living in the inner Isthmus and on the North Shore, as well as the rural North-West. The rural area units will not contain many people, so in actual numbers not percentages, most of the professional, technical and scientific sector workers will live in the city.
The fit between where people live and work in the M sector is pretty good from a planning perspective. Proximity helps a lot with accessibility. The sector will likely grow. More employment located in the city centre is positive, but will the future workers find a home location that fits their desires? If most of the future housing capacity is not in the Inner Isthmus or the North Shore coastal strip, then where do they go?  Are they all foot lose workers who might decamp to other cities and countries if they cant find their perfect home in the city?
So where does this all lead us? Well one purpose of planning is to ensure that the city has an efficient labour market. Alain Bertaud in his paper ‘Cities as a Labour Market’ makes the case for planning to support market processes:
“Increasing mobility and affordability are the two main objectives of urban planning. These two objectives are directly related to the overall goal of maximizing the size of a city’s labor market, and therefore, its economic prosperity.
“Mobility” is the ability to reach any area of a metropolitan area in as short a travel time as possible, and “affordability” is the ability of households and firms to locate in whichever area they deem will maximize their welfare”.
Sounds good. But is it that simple? Whose mobility and affordability do you plan for? Do we support the growth of the M sector, or try to slow the relative decline of the higher paying FIRE sector and its bigger contribution to GDP? Will improving affordability of the inner Isthmus and coastal areas (basically, a lot more houses in these areas) mean that the appeal of these suburbs to workers in the M sector will actually decline as lifestyle is important to them (being mostly city hipsters?). Or do you put your money into improving accessibility from other locations, such as from out in the rural north-west?
Next blog - what about all the other workers, especially the lower paid and less skilled? Where do they live and work?

The city as a labour market


What type of jobs are offered by a city and the location of those jobs are important factors in shaping a city’s urban form. The type of jobs influences household incomes, while the location of jobs influences the demand to live in different parts of the city, for example.


As noted in my blogs of 6 June 2017 and 26 September 2016, in theory as a city gets bigger, then productivity per worker should increase and along with this, incomes. Yet the data for Auckland suggests only sluggish growth in productivity (as is true for the country as a whole). Many people have noted that household incomes had flat lined over the past 10 years or so, after allowing for inflation. Around the corner is the rise of robots and artificial intelligence. Is the future going to be a mix of “low-skill/low-pay” and “high-skill/high-pay” jobs?  How can we make the city more affordable for the low pay component, and not loose the high paying sector?  

On the location front, many jobs are locating in the central area, which is positive from the point of view of accessibility to labour markets, but also many jobs are locating in the south. Do we need to plan for more housing in the south, rather than to the north or west?
So what can the location and type of jobs in Auckland tell us about Auckland’s future urban form and what role might planning have in shaping that picture?
In this blog I want to look at the question of the type of jobs being created in the city. In another blog, I will look at location issues.

First up, the big picture. As of mid 2016, Stats NZ data recorded 724,310 people employed in the Auckland Region.  With a resident population estimated at 1,614,400, this equals 448 jobs per 1,000 resident. This is up from 429 jobs per 1,000 residents in 2001. So jobs have been growing faster than the population in general.  However over 2001 to 2016, the median age of Auckland’s population has dropped (not increased). The number of people of working age (as defined by the number of 15 to 65 year olds - not the most perfect classification these days of extended training for younger adults and more older adults working, but never mind) has increased from 67% of the total population in 2001 to 68% in 2016.
What type of jobs have increased the most? Below is the number of people employed in 2001 and 2016, organised by Stats NZ standard industrial codes. Note, the number of employees is the head count of all salary and wage earners. It therefore covers full and part time workers.

Figure One: Number of employees by industry sector, 2001 and 2016, Auckland Region
The expected pattern is the increase in the number of people employed in the service orientated sectors like education, health care and the retail trade; this is the story of the rise of the post industrial consumer city. But what stands out the most is the growth of the ‘M’ sector - professional, scientific and technical services.
The next graph organises employment change between 2001 and 2016 by the absolute change per sector, from the smallest to the largest change.  
Figure Two: Change in number of employees by industry sector, 2001 to 2016, Auckland Region


The on-going decline in manufacturing jobs is apparent. While the number of people employed has dropped, manufacturing output may have increased (fewer people, more automation for example).
Previous analysis of employment changes often stressed the growth of the FIRE sector - finance, insurance, information technology, real estate and the like - as the countervailing trend to the decline of manufacturing. But these sectors do not seem to have grown by much. Again output may be up, but employment is stable. It is possible that over the next few years automation and AI will have a big impact on the traditional ‘white collar’ jobs in the finance, banking and insurance sectors.
Some of the changes in employment are due to population growth. When we look at jobs per 1,000 residents, then the changes that are the result of structural shifts between 2001 and 2016 are more obvious.
Figure Three. Employees per 1,000 residents by industry sector, 2001 and 2016, Auckland Region

And to make it really clear, here is the difference between 2001 and 2016.

Figure Four: Change in employees per 1,000 residents, 2001 to 2016, by industry sector, Auckland region



Construction related jobs are up; not surprising due to the growth of demand for infrastructure, housing and commercial space. Employment growth in the accommodation and food services sector will likely be the result of the tourism boom, while growth in education and training employment may reflect, in part, education as an ‘export’. The increase in health care may be the result of the growing number of older adults.  The FIRE sector hasn't really changed much. Even MBIE in their forecasts of future employment at the national level are not very bullish on the sector (2).
The ‘odd one out' is the ‘M’ sector. Looking at the growth of the professional, scientific and technical services sector, Stats NZ break down the category into two main sub categories, as set out in Table One. Employment in computer design and related services has grown fast, but in absolute terms, traditional professional jobs have still grown the most.
Table One: Number of employees 2001 and 2016, industry sector “M’, Auckland region

6,100
2016
62,800
16,100

10,000



It is fun to poke around in the next layer down. Taking the first column of the above table, we can break down the growth in the ‘core’ professional sector to the following:
Figure Five: Change in number of employees for industry sectors M 691 - M 699, Auckland region.  


So most of the growth in the sector has been management (M696) and RMA-related consultants (M692)?  
  • M692 covers Architectural, Engineering and Technical Services
  • M696 covers Management Consulting Services.
Add to this some computer coders busy making new apps and games. Is this what Auckland’s prosperity is to be based on, if the economy is to grow not just by simple population expansion or reliance on low paid jobs serving tourists?   
At least the number of lawyers has not grown too much!
Can the professional services sector get much bigger? It has gone from 9% of regional jobs to almost 11% between 2001 and 2016. The NZ figure is 8% as of 2016, so Auckland has a relative advantage in this sector.  US data (which may not be directly comparable) suggests that the sector could get to 13% of total employment at the national level. So perhaps 15% at the regional level given the large urban population of Auckland. But the sector is very dependent upon highly skilled workers, and so there may be 'supply' constraints, unless we import many more knowledge workers.
It is also useful to compare the change in the number of jobs per sector with average earnings for people employed in each sector. The following is national level data, rather than regional, and so may understate average earnings in the Auckland Region. It is also not based on equal measures of hours worked, so some of the low pay in some sectors may reflect more limited hours per employee. But the general pattern is the issue, rather than the detail. The graph shows average earnings per week (ordinary and overtime) per employee, by industry sector, for 2016.

Figure Six: Average weekly earnings, by industry sector, 2016, NZ
 
The point of this exercise is that some of the job categories that have grown the most tend to be the lower paying jobs, such as jobs in the accommodation, retail, construction and healthcare sectors. The number of jobs in the higher paying FIRE sectors have not increased that much. Perhaps this is why productivity has stalled and household incomes are not rising by much. In the middle is the professional and education training sectors.
The on going decline of manufacturing jobs, the levelling off of employment in banking and finance and the substantial growth of the professional, scientific and technical services sector is not dissimilar to other developed countries.
Is this the emergence of the fourth industrial wave that various people talk about? The fourth industrial wave has been described as follows by the World Economic Forum (Note 2):
“The First Industrial Revolution used water and steam power to mechanize production. The Second used electric power to create mass production. The Third used electronics and information technology to automate production. Now a Fourth Industrial Revolution is building on the Third, the digital revolution that has been occurring since the middle of the last century. It is characterized by a fusion of technologies that is blurring the lines between the physical, digital, and biological spheres”.
This is basically the same thesis as the sixth kondratieff cycle I discussed in my blog of 6 July 2017, although somewhat confusingly the number of ‘waves’ and 'revolutions' vary (4 or 6). In terms of implications of this fourth revolution, the Forum noted the following, which kind of mirrors what seems to be happening in Auckland:
“In the future, technological innovation will also lead to a supply-side miracle, with long-term gains in efficiency and productivity. Transportation and communication costs will drop, logistics and global supply chains will become more effective, and the cost of trade will diminish, all of which will open new markets and drive economic growth.
The revolution could yield greater inequality, particularly in its potential to disrupt labor markets. As automation substitutes for labor across the entire economy, the net displacement of workers by machines might exacerbate the gap between returns to capital and returns to labor. On the other hand, it is also possible that the displacement of workers by technology will, in aggregate, result in a net increase in safe and rewarding jobs”.
The last sentence seems a bit hopeful. It is hard to see a bunch of displaced manufacturing and retail workers turning themselves into management consultants overnight. Whether most new jobs will be ‘safe’ is also a bit uncertain.
What the description seems to miss is that while transport, trade and communication costs have dropped as globalisation opens up export and tourism markets, labour markets have also been opened up to large pools of lower paid workers via immigration, while financial markets are subject to massive flows of capital looking for quick returns. Much growth in employment has been in sectors that lack secure employment, like retail, hospitality and training. Even the vaunted professional services sector is likely to comprise many sole and small operators calling themselves consultants, hanging on from job-to-job.  

All these trends have affected Auckland - average household earnings have not increased by much over the past 10 years, productivity growth has stalled, while asset prices have inflated. Meanwhile, a small but important sector have seen incomes rise and with this demands for a better quality environment within which to live, work and play.  

Is the issue for Auckland how to capitalise on the growth in the professional services sector, adjusting to the likely relative decline of the finance, insurance and banking sectors while making the city less expensive to live in for all the lower paid service workers tending to the tourists, shoppers and rest home residents?
