4.4.2 Heterogeneity oa liphello kalafo

Liteko ka tloaelo lekanya phello kakaretso, empa phello e ka ba tse fapaneng bakeng sa batho ba fapaneng.

The senotlolo sa bobeli khopolo ea ho fallela ka nģ'ane ho liteko tsa le bonolo hakana ke heterogeneity oa liphello kalafo. The teko ea Schultz et al. (2007) matla bontša kamoo kalafo tšoanang ka ba le liphello tse fapaneng leetong la mefuta e fapaneng ya batho (Figure 4.4), empa Analysis ena ea heterogeneity ha e le hantle e sa tloaelehang haholo bakeng sa teko analoge lilemo tsa ka. Most analoge liteko dilemo akarelletsa palo e fokolang ea barupeluoa hore ba tšoaroa joaloka fapanyetsana "diwidget" hobane hakaalo ka tsona e tsejoa pele ho kalafo. Ka liteko dijethale Leha ho le joalo, bara bana liqholotso ya data tse ka tlaase ho moo li neng li atile hobane bafuputsi atisa ho ba le barupeluoa ho feta 'me u tsebe ho eketsehileng ka tsona. Tikolohong ena fapaneng tsa data, re ka hakanya heterogeneity oa liphello kalafo e le hore ho fana ka leseli lefe mabapi mabapi le kamoo kalafo ea sebetsang ho, kamoo ho ka ba ntlafala, hona e ka targeted ho ba boholo ho ka etsahala hore ba rue molemo.

mehlala e 'meli ea heterogeneity oa liphello phekolong ea moelelo oa Litloaelo tsa phedisano le ho sebedisa matla tsoa etsa lipatlisiso eketsehileng ka Home Energy Reports. Taba ea pele, Allcott (2011) ba ne ba sebelisa khōlō sampole boholo (600.000 malapa) ho arola ka ho eketsehileng le sampole ena le hakanya le phello ea Energy Report Home ke decile oa tšebeliso matla pele ho kalafo. Ha a ntse a Schultz et al. (2007) fumanoa phapang pakeng basebedisi boima 'me leseli, Allcott (2011) fumane hore ho na le boetse ne ho se tšoane ka hara sehlopha se le boima' me leseli la mosebedisi. Ka mohlala, basebedisi petepete (bao ka decile holimo) fokotswa tshebediso bona matla ka makhetlo a mabeli ha ho bapisoa le motho a bohareng ba sehlopha sa basebedisi boima (Figure 4,7). Ho ekelletsa moo, ka go fopholetsa phello e ke boitšoaro pele ho kalafo boela a senola hore ho na le e ne e se ba le phello e Boomerang esita le bakeng sa basebedisi bobebe (Figure 4,7).

Figure 4,7: Heterogeneity oa liphello phekolong ea Allcott (2011) . The fokotseha ka tshebediso matla e ne e fapane bakeng sa batho ba deciles e fapaneng ya tshebediso ya motheo.

Ka thuto ea amanang, Costa and Kahn (2013) a hakanya hore ho atleha tsa Energy Report Home ne Vary thehiloeng likhopolong tsa e participant lipolotiki le hore phekolo ea ka 'na ha e le hantle etsa hore batho ba nang le likhopolo tse itseng ho eketsa sebelisa matla a bona motlakase. Ka mantsoe a mang, ba ile ba a hakanya hore Home Energy Reports ka 'na ua theha le phello e Boomerang tse ka bang mefuta e sa batho. Ho hlahloba monyetla o ena, Costa le Kahn di ne tsa kopanngwa ea Opower ya data le data ya rekileng ho e aggregator tsa mokga wa boraro e neng e akarelletsa tlhahisoleseding e jwalo ka mokga ngodiso lipolotiki, menehelo mekhatlong tikoloho, le ho kopanela ntlo ea mananeong a matla ntjhafatswang. Le sete ea datha ena kopantse, Costa le Kahn fumane hore Home Energy Reports hlahisoang liphello ho emela tšoanang bakeng sa barupeluoa ba nang le likhopolo tse fapaneng; ho ne ho se bopaki ba hore sehlopha leha e le efe bontšitse liphello Boomerang (Figure 4,8).

Figure 4,8: Heterogeneity oa liphello phekolong ea Costa and Kahn (2013) . The hakanngoa karolelano kalafo le phello bakeng sa sampole eohle e -2,1% [-1,5%, -2,7%]. Ke kopantseng tlhahisoleseding ho tswa teko le boitsebiso bo mabapi le malapa, ho Costa and Kahn (2013) a sebelisa letoto la dikai dipalopalo ho hakanya phello kalafo bakeng sa dihlopha tsa tse tobileng tseo tsa batho. Likhakanyo tse peli tse hlahisoang bakeng sehlopha ka seng ka lebaka likhakanyo tsa itšetleha ka covariates ba akarelletsoang dikai bona dipalopalo (sheba Model 4 le ea mohlala 6 Lethathamo 3 le Lethathamo 4 Costa and Kahn (2013) ). Ka mohlala sena se bontša, kalafo liphello e ka ba tse fapaneng bakeng sa batho ba fapaneng le likhakanyo tsa ea liphello kalafo e tlisoang ke ho dikai dipalopalo ka itšetleha ka lintlha tse qaqileng tsa dikai bao (Grimmer, Messing, and Westwood 2014) .

Joalokaha mehlala ena e 'meli e bontša, a le lilemo li dijethale, re ka susumelletsa ho ka go fopholetsa karolelano liphello kalafo ho ka go fopholetsa ea heterogeneity oa liphello kalafo hobane re ka ba le barupeluoa ba bangata ho feta' me re tseba ho eketsehileng ka hore na barupeluoa tseo. Ho ithuta ka heterogeneity oa liphello kalafo ka etsa hore ho shebiloe haholo ya kalafo moo e ke atlehang ka ho fetisisa, ho fana lintlha tse fanang ka susumelletsa ntshetsopele e ncha ka khopolo eo, le ho fana ka maele mabapi mochine e ka khonehang, e leng sehlooho tseo ke hona joale retelehela.
