Model 3. The Spill-Over Effect

«1 = «10 - anDγ |
(15) |
2= = β10 («10 + αιιDγXc⅛o + «11DY2) (16)
The point of departure for calculating β is now
GY = «0 + (αw - a11DY)GI + βw (aω + auDY)(aw + ⅛DY2)GI2 (17)
GY = «0 + (aw - anDY)(γ0 + 71 DY)
+ βω (aw + auDY)(aw + anDY2)(γ0 + γυDY2) (18)
gy = C⅛ + O1070 + CW1dy - O11Y0 DY - a11Y1DY2
+ β10 (a10 - anDY1)(a10 - a11DY2)(γ0 + γ1DY2) (19)
If the neighbour income is assumed to be the average income DY2 = 0 we have
gy = C⅛ + O1070 + CW1dy - O11Y0 DY - CW1dy2
+ β10 (»10 - ⅜1Dγ1)CW0 (20)
gy- (c⅛ + aw70 ) - β10CC10a10γ0 = <⅞7∣ Dγ - »1170DY- ‰7∣dy'

DGY = («1071 - «1170 - β10ana1070)DY - an71DY2 (22)
Model 4. Attraction with Declining Force and Other Factors
