2/27 Introduction High levels of (structural) vacancy Concentration in specific areas and buildings Social security & criminality Negative externalities related to structural vacant buildings? Positive externalities are often assumed Landmark buildings Public space: proximity to parks & water bodies Difficult to measure and quantify: spatially lagged variables Function of distance Negative Externalities and Structural Vacancy

3/27 Introduction Negative Externalities and Structural Vacancy Source: Thibodeau (1990)
4
4/27 Introduction Isolating the effect: Market conditions: rental adjustment equation Omitted variables: proxy for neighborhood quality Negative Externalities and Structural Vacancy
5
5/27 Structural Vacancy “Structural” nature: three consecutive years Visibility of vacancy: at least 50% of the building is vacant Operationalization
6
6/27 2003 Number of Structural vacant buildings = 1

8/27 2005 Number of Structural vacant buildings = 17
9
9/27 2006 Number of Structural vacant buildings = 34
10
10/27 2007 Number of Structural vacant buildings = 32
11
11/27 2008 Number of Structural vacant buildings = 29
12
12/27 2009 Number of Structural vacant buildings = 38
13
13/27 2010 Number of Structural vacant buildings = 54

21/27 Weight factor Spatially Lagged Variable Model Specification Distance 0 R=250m. R=500m. R=750m. 1 R=150m. How to measure distance: As the crow-flies Along the road network
22
22/27 Distance Weight factor 0 R=250m. R=500m. R=750m. 1 R=150m. Spatially Lagged Variable Model Specification
23
50 m r=500m 450 m 300 m Impact depends on: Distance Building size
24
24/29 Negative Externalities of Structural Vacant Offices Best performing model assumes: Constant distance relationship with threshold distance at 250m. Distance measured: as the crow-flies 0 R=250m. 1 Distance Impact: independent of the size of the structural vacant building
