I think everyone needs to go back to Economics 101:Price is a function of Supply and Demand. Do you remember those curves in Freshman Micro where the Supply and Demand Curves shift in and out along the X axis based on underlying changes? And the intersect point would give you Price?
Well, imho, there is no reason to assume that Price Discovery is any different with the world's oldest profession?
Looking at Demand first, you could argue that in a period of sharp economic downturn, coupled with asset price declines (e.g. zero to negative inflation), there would be a reduction in the quantity of prospective users of RA services and the amount of disposable income they can commit to this passtime. What the correlation between these two factors and overall demand would be is hard to estimate (what a fascinating topic for a Ph.D thesis in economics!), but I readily accept the notion that demand would decline at a slower rate than overall economic activity. So you shift the Demand curve a little to the left...
Supply is the big difference here, imho, especially in this day and age of the internet, which allows not only much more efficient price discovery, but makes it so much easier (and less risky) for the provider to establish contact with the client. What I would foresee happening is a large new supply of non/semi pros using the internet to access a needed source of additional cash. From university students whose grants and loans are reduced, to struggling young adults, to mothers/housewives desperate to make the mortgage or medical payments, I believe that Supply would increase materially, and that many of these new entrants would be happy to on an infrequent basis (e.g. once or twice a week) and earn a couple of hundred dollars for 2-3 hours. They would constitute a significant source of new supply prepared to offer a product of variable quality (great to dreadful) at a significantly below market rate. And the internet makes it so much easier for them to access prospective clients. IMHO. many would not even bother with RB type sites, but would head for the SugarDaddy type sites, which would allow them a "go slow" start where they can meet prospects before committing to anything and then set up a relationship and schedule as it suits them. After all, they probably would be more than happy to net $1,500-$2,000 a month for two or three weekly appointments.
I therefore see a very considerable increase in supply, some of which would be providing at a high quality of service (SBs tend to have a lot less "rules" than RAs), which would materially fulfill demand from middle to upper echelon buyers. So there would be a significant shift in the Supply Curve to the left, thereby setting Price (the intersection of the Supply and Demand curves) at a lower point.
Ah! Supply Side Economics! If only Laffer and his gang had written a treatise on this particular market...
And fwiw, I have found that there are some wonderful SBs out there who provide both outstanding value for money and a great service. I fully accept that SBs aren't everyone's cup of tea, but remember, all you have to do is take some reaosnable amount (15%-30%?) of the demand out of the market to watch price move seriously downward (for those who haven't been watching the Real Estate Market for the past three years).
Anyway, my two cents worth...
