4.4.2 Heterogeneity o pānga maimoatanga

Ngā tikanga ine i te pānga toharite, engari ka taea e te pānga e rerekē mō te iwi rerekē.

Te whakaaro matua tuarua mō te neke tua atu ngā ohie he heterogeneity o pānga maimoatanga. Te whakamātautau o Schultz et al. (2007) puai whakaatu pehea te maimoatanga taua taea whai pānga rerekē i runga i ngā momo o te iwi (Figure 4.4), engari ko te mau tenei tātaritanga o heterogeneity tino rerekē mō te whakamātau tairitenga tau. Te nuinga o ngā pakeke tairitenga ngā he maha iti o ngā kaiuru e kua tukinotia rite whakawhiti "widget" no te mea iti e pā ana ki a ratou te mohiotia mua maimoatanga-. I roto i ngā mamati, Heoi, he iti noa no te ahu kairangahau ki te whai atu ngā kaiuru me te mohio atu e pā ana ki a ratou ēnei whakatiki raraunga. I roto i tenei taiao raraunga rerekē, ka taea e tatou e tata heterogeneity o pānga maimoatanga roto i te tikanga ki te whakarato i tīwhiri e pā ana ki te pehea te maimoatanga mahi, me pehea e taea te whakapai ake te reira, a pehea e taea te hāngai te reira ki te hunga nuinga pea ki te whai hua.

E rua ngā tauira o heterogeneity o pānga maimoatanga i te horopaki o te tikanga pāpori, me te whakamahi pūngao mai i te rangahau atu i runga i te Kāinga Energy Pūrongo. Tuatahi, Allcott (2011) e whakamahia ana i te rahi o te tauira nui (600,000 whare) ki te wahia atu te tauira me te whakatau tata i te pānga o te Energy Report Home i te kura o te whakamahi pūngao mua maimoatanga-. Ahakoa Schultz et al. (2007) i kitea ngā rerekētanga i waenganui i ngā kaiwhakamahi taimaha, me te marama, Allcott (2011) i kitea e reira i hoki ngā rerekētanga i roto i te rōpū kaiwhakamahi taimaha, me te marama. Hei tauira, te kaiwhakamahi taumaha (te hunga i roto i te kura runga) heke to ratou whakamahinga pūngao takiruatia ta rite te tangata i roto i te waenganui o te rōpū kaiwhakamahi taimaha (Figure 4.7). I tua atu, ine i te pānga i te whanonga mua maimoatanga-whakakitea ano hoki e kore ko te pānga boomerang ara mo te kaiwhakamahi māmā (Figure 4.7) ki reira.

Whakaahua 4.7: Heterogeneity o pānga maimoatanga i Allcott (2011) . ko rerekē hoki te iwi i roto i Report rerekē o te whakamahi tauanga te hekenga i roto i te whakamahi pūngao.

I roto i te ako e hāngai ana, Costa and Kahn (2013) ie e taea tēnā e hāngai ana ki te whai huatanga o te Energy Report Home runga Māoritanga tōrangapū o te whai wāhi, me te e te maimoatanga ai meinga mau iwi ki etahi mātāpono ki te faarahi i to ratou whakamahi hiko. I roto i te mau parau te tahi atu, ie ratou e ai te Home Energy Pūrongo kia hanga he pānga boomerang mo etahi momo o te iwi. Hei aromatawai i tenei pea, Costa ko Kahn hanumi te raraunga Opower ki raraunga hokona i te Aggregator tuatoru-rōpū i ngā mōhiohio pēnei i rēhita tōrangapū rōpū, ô ki ngā rōpū taiao, me te whai wāhitanga whare i roto i ngā hōtaka pūngao whakahou. Ki tenei huingararaunga hanumi, kitea Costa me Kahn e whakaputaina te Home Energy Pūrongo pānga whänui rite mō ngā kaiuru ki te mana'o rerekē; kahore he taunakitanga e faaite i tetahi rōpū pānga boomerang (Figure 4.8).

Whakaahua 4.8: Heterogeneity o pānga maimoatanga i Costa and Kahn (2013) . tata te pānga maimoatanga toharite mō te tauira katoa he -2,1% [-1,5%, -2,7%]. Na roto i te whakakotahi ngā mōhiohio i te whakamātautau ki te kōrero e pā ana ki te whare, Costa and Kahn (2013) e whakamahia ana i te raupapa o ngā tauira tauanga ki te whakatau tata i te pānga maimoatanga mō ngā rōpū nui motuhake o te iwi. E te aroaro rua tata mō ia rōpū no te whakawhirinaki nga whakatau tata i runga i te covariates ngā ratou i roto i o ratou tauira tauanga (kite whakatauira 4 me te tauira 6 i roto i te Ripanga 3 me te Ripanga 4 i roto i Costa and Kahn (2013) ). Ka rite ki tenei tauira fakatātaa'i, ka taea e ngā pānga maimoatanga e rerekē mō te iwi rerekē me whakatau tata o ngā pānga maimoatanga e haere mai i ngā tauira tauanga e taea whakawhirinaki i runga i nga taipitopito o aua tauira (Grimmer, Messing, and Westwood 2014) .

Ka rite ki enei tauira e rua whakaatu, i roto i te ao mamati, e nehenehe tatou e te neke atu i tata pānga maimoatanga toharite ki ine i te heterogeneity o pānga maimoatanga no te mea e nehenehe tatou e rave rahi atu mau piahi, me matou e matau atu e pā ana ki te hunga whai wāhi. Ako e pā ana ki heterogeneity o pānga maimoatanga e taea taea ngā o te maimoatanga i reira he mea whai hua tino, whakarato meka e whakaongaonga whanaketanga ariā hou, me te whakarato tīwhiri e pā ana ki te huarahi ka taea, te kaupapa ki te tahuri ai ahau inaianei.
