    We investigate the mechanisms by which public policy affects the price of new housing in Medellin, Colombia. Using a vector autoregressive structural model we show that shocks to the real cost of credit (UVR) have a highly elastic, short-run negative effect on therealpriceofhousingpersquaremeter. Further,usingasystemofequationsestimated using seemingly unrelated regression (SUR) and three-stage OLS regression, we show that a reduction in the mortgage rate [via subsidies through the Reserve Fund for Stabilization of the Mortgage Portfolio (FRECH)] has a positive impact on the demand for housing, which generates upward pressure on the price of new housing. Through these mechanisms public policy plays a fundamental role in the dynamics of the construction sector.

    Impacto del COVID-19 sobre la demanda y oferta de vivienda nueva No VIS en Colombia
    (Universidad EAFIT, 2022-03-09) Álvarez Zuluaga, Daniela; Betancur Carvajal, Catalina; García Rendón, John; Universidad EAFIT; Universidad EAFIT; Universidad EAFIT
    In this paper we examine the impact of COVID-19 on the demand and supply of new No VIS housing in Colombia. Using a model of Seemingly Unrelated Regression, we find that COVID-19, measured through the number of infections, and the interest rate in UVR present an inverse relationship with the No Vis new housing supply, decreasing the quantities offered during the most critical months of the pandemic. In addition, the price index for new housing complies with the law of supply, which can be validated with what has been observed in 2021 regarding the growth in the launch of new real estate projects, at the same time that prices have also been higher, justified, in part, by the increase in costs as a result of the pandemic.
