Jassy OK, whats your view of applying standard economic theories, such as the SSNIP test, to the housing market (each sector)? A few posters above have made useful comments which hint at lack of competitive constraints, no effective competition, higher margins and small scale limiting entry to the market, limited countervailing buying power and so on - all standard indications of a relatively static market which lacks competition.
You seem to indicate that you would tackle this with greater state control, but that would seem likely to result in more market dominance and lack of plasticity, not less. I think some useful comments have been made by others with regards to releasing more brownfield sites, I also think that increasing self build by making a planning rule that for example 20% of all new builds have to be self build. I also think red tape could be cut down, reducing additional costs on FTBs - too much of what is required in terms of surveys, EPCs etc is poor implementation by the State of passing costs onto individuals of services which are already paid for in terms of general taxation. Personally, I think we are too London-centric and that developing better infrastructure so that the rest of the country could be more effectively energised would be a good idea.
But since you claim to be very knowledgable about economics and statistics, whats your suggestions? And why have they not been adopted, if they are so good? Because I can't help noticing that what you have suggested so far tends to have some basic mistakes, such as ignoring the application of the ECHR or Charter, competition law constraints and public procurement rules, as well as being far too simplistic.
I also can't help noticing, despite my evident lack of economic knowledge, that you have made no attempt to define a relevant market, nor what the abuse is - dominance by one or more parties, excessive pricing, etc.. Are there are any examples of countries with regimes you could point to who have either avoided or cured these problems?
