To explore the relationship between prices and communing costs, we use a difference in difference spatial model. Parametric and non-parametric estimations suggest a negative and significant impact of commuting costs on property values for dwellings far away from employment centers. The estimated price elasticity with respect to commuting costs for housing located in distant zones, indicates that a 1% increase in fuel price, reduces property values in 1.48%. Non-parametric Geographically Weighted Regression (GWR) showed to outperform traditional Spatial Autoregressive (SAR, SEM) models.","PeriodicalId":285424,"journal":{"name":"TransportRN: Transportation & Spatial Organization (Topic)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121824755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Elasticities of factor substitution for the Constant Elasticity Substitution (CES) production function is estimated in spatial econometric models with consideration of spatial dependence. CGE simulations adopting different elasticities of factor substitution show a difference between spatial econometric estimation and traditional OLS estimation. Although the differences are relatively small in this aggregate case study, implications for more sensitive disaggregated regional models are clear.","PeriodicalId":285424,"journal":{"name":"TransportRN: Transportation & Spatial Organization (Topic)","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116763638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
