Why do positive areas, reminiscent of Ile de France, proceed to pay attention wealth and inhabitants, whilst others fight to expand? The important thing lies within the virtuous – or vicious – circle of density. The cost of actual property performs an important position on this strategic factor at a time of conceivable reindustrialization.
The problem of territorial financial building is basically a hen and egg tale. As a hen comes from an egg laid through a hen… a territory wishes employees to thrive… however those self same employees most effective settle there if the territory is horny sufficient. Due to this fact, a dense territory gives higher skilled possibilities, but additionally sought-after facilities, reminiscent of colleges, hospitals, theaters, delivery and even public services and products… Such a lot of causes for staff to choose extra evolved areas.
We studied this dynamic thru a selected query: how do firms positioned in carefully populated spaces arrange to draw skill in opposition to all odds? The solution will also be discovered within the financial idea of “compensation of differences”, and is the reason the salary hole according to professions and heterogeneity of territories.
When truth contradicts idea…
In step with this repayment idea, the salary hole will also be defined through each folks’ abilities and dealing prerequisites – which come with high quality of lifestyles. The harder the prerequisites, the upper the salary will have to be to draw employees. In different phrases, consider two folks with equivalent abilities, if one in every of them lives in a much less dense house than the opposite, providing fewer facilities, then logically he must be paid extra (to catch up on this distinction).
On the other hand, the information tells a special tale. To the contrary, as noticed in Desk 1 beneath, moderate gross hourly wages decline with density. For executives, as an example, they cross from €43 within the densest spaces to €35 in the slightest degree dense spaces – a distinction of greater than 23%.

However this statement is incomplete. As a result of the benefits associated with density have a worth: costlier housing, city congestion, upper residing prices… Housing costs, specifically, as proven in Desk 2, cross from 1,357 euros according to m2 in the slightest degree dense spaces to three,042 euros according to m2 in probably the most dense spaces, the ratio between the primary and closing quartiles is bigger than 1 and a couple of.

Two intuitions emerge from those figures:
Actual property buying energy is a key compensating issue for families residing in low-density spaces, as housing represents an important a part of the finances (about 20% in 2017) (Insee, Family Source of revenue and Property, 2021) and its worth varies very much relying on native density.
Moreover, falling assets costs have a tendency to play a compensatory position when different density-related advantages (client costs, high quality of lifestyles, get entry to to services and products, and so forth.) decline. This repayment is due to this fact extra pronounced in much less dense spaces and for individuals who in particular respect the advantages of city density.
Briefly, low density is compensated now not such a lot through wages in absolute price, however through relative residing requirements, which we will be able to measure through the ratio of source of revenue to assets costs.
Much less dense, however a greater way of life
How are we able to ascertain that residing in a much less dense house actually ends up in an build up in residing requirements, particularly for probably the most certified? To respond to this query, we now not have to match simply salaries, but additionally the ratio of source of revenue to price of residing – which we estimated through integrating the cost of actual property.
This can be a tough workout, as a result of many elements come into play: particular person abilities (age, level, gender), hard work marketplace traits (task provide and insist, trade group, exports, automation), and in the end territorial components (density, infrastructure, agglomeration results). If we don’t take those variables under consideration systematically, we chance confounding the true impact of density with different determinants.
To triumph over this impediment, we mobilized a large amount of knowledge: all hard work contracts signed within the production trade in 2019, enriched with corporate knowledge and native signs. This statistical richness allowed us to higher isolate the particular impact of density, through evaluating equivalent profiles in territories of various density.
A wage that rises like the cost of actual property
The consequences are transparent. The extra density will increase, the extra nominal gross wages upward thrust… however the buying energy of actual property declines. A 1% build up in density will increase the hard work time required to buy a sq. meter of housing through 0.15%. In different phrases, wages are emerging with density, however now not sufficient to catch up on the explosion in actual property costs.
This impact in particular impacts managers. They’re those who see their wages build up probably the most in dense spaces… however they’re additionally those who lose probably the most in actual property buying energy. By means of opting for to settle in a much less dense house, they settle for a wage sacrifice however have the benefit of a considerable achieve in housing.
Why is that this “bonus” upper for executives? From a repayment point of view, our outcome displays that managers are maximum delicate to density advantages, as they’re prepared to have the benefit of the lack of quite upper actual property buying energy.
BFM Industry – 2022. An issue of public coverage
Our effects, then again, will have to be interpreted with warning. A number of components deserve additional investigation:
Ability degree of employees: within the absence of knowledge on talent degree, it’s conceivable that the noticed variations partially replicate the disparity in profiles between dense and not more dense spaces. If shall we higher isolate the impact of this variable, the top rate known would most likely be much more pronounced.
Circle of relatives measurement: mobility choices are hardly taken by myself. The beauty of the territory additionally is determined by jobs for the partner, college for youngsters, or even well being infrastructure.
Evolution over the lifestyles span: priorities trade with age. Proximity to a highschool does not topic with out adolescent youngsters, whilst get entry to to care turns into an important as we age.
The impact of Covid and far flung paintings: the information used is from 2019. On the other hand, the well being disaster has changed the arbitrage between massive facilities and not more dense territories, giving a brand new impetus to far flung paintings.
We remind you that much less dense spaces are herbal applicants for reindustrialization, if just for evident land causes. Attracting certified employees is a huge problem for firms. Public coverage will have to combine those issues of employment beauty in opposition to density, whilst companies can discover a steadiness through finding there and making the most of a less expensive price of residing, equipped facilities and infrastructure don’t seem to be deterrents.
The rising hole on this house between (very) dense spaces and not more dense spaces dangers completely depriving spaces that experience important doable for commercial (re)building. To unravel the hen and egg downside and begin virtuous circles, most effective coordination between public government and companies on the native degree will have the ability to permit sustainable reindustrialization, which can get advantages staff, companies and territories.
