Developers from all over the country have been asked to make a €2,000 contribution to pay for a study of Nama, the national asset management agency, as the sector grows increasingly nervous over government plans to move all property loans off bank balance sheets within weeks, writes Emmet Oliver.

The Construction Industry Federation (CIF) has written to the property development segment of its membership in recent days looking for the contribution. The money will be used to commission an economic analysis of Nama, by UK research company Lombard Street.
