Good things come in pairs: Block trade in housing market. 8th International Conference on Econometrics and Statistics (EcoSta 2025), Waseda University, Tokyo, Japan.http://hdl.handle.net/20.500.11861/27846While owners of single-family homes can extend and redevelop their properties to satisfy their increased demand for space, condominium owners do not have the same flexibility. When the characteristics of the housing stock stay unchanged amidst a changing income distribution, some households may choose to get around the mismatch between the demand for and supply of space in a given location by buying multiple units in one trade, which is referred to as block trading. An overlapping generation model is developed to study this kind of block trading in the housing market, and the model's implications are tested with microdata from Hong Kong.enConference Paper
