Despite the quantity distortion that housing supply constraints cause, I show that the socially optimal tax for using a road is still its marginal external cost. However, the artificial housing scarcity generates potential profits, which are either accrued by the construction sector or absorbed by raising land prices. If land rents and developer profits are not fully recycled within the urban area, the Pigouvian road tax ceases to maximize the welfare of that area. To maximize local welfare, road tolls should then lie below (above) their Pigouvian level insofar as they increase (decrease) housing demand in areas where supply cannot be adjusted upwards. I derive analytical formulas for the impact of other spatially relevant aspects on the optimal road tax. Property taxes and spatially invariant lump-sum transfers can both render the Pigouvian rule for taxing road externalities suboptimal.</p></div>","PeriodicalId":45761,"journal":{"name":"Economics of Transportation","volume":"35 ","pages":"Article 100324"},"PeriodicalIF":2.8,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44203986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overall, we find no evidence of reduced serious or fatal accidents following the policy, indicating most drivers are not significantly changing their risky behaviours when confronted with higher penalties. There is, however, some evidence of fewer accidents in more economically advantaged areas. This suggests that drivers are responding to the amount of the fine increase rather than the income share and wealthier drivers are therefore more affected.</p></div>","PeriodicalId":45761,"journal":{"name":"Economics of Transportation","volume":"34 ","pages":"Article 100311"},"PeriodicalIF":2.8,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44542719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper studies the relationship between the development of the Portuguese motorway network between 1981 and 2011 and the growth of population and employment at the local level. We address the endogeneity of the geography of motorways using instrumental variables based on a map of dirt roads from the late 18th century and the main roads of a 1945 road plan. Our findings suggest that, on average, motorways caused large increases in population – and even larger increases in employment – in the municipalities that received them. We also find that motorways contributed to suburbanisation, as the impact of motorways on population growth (but not on employment growth) is stronger in suburban municipalities. Another important nonlinearity is that motorways appear to have influenced urban agglomeration dynamics, as their effect on the growth of the local population between 1981 and 2011 depends on the size of the local population in 1970.</p></div>","PeriodicalId":45761,"journal":{"name":"Economics of Transportation","volume":"34 ","pages":"Article 100302"},"PeriodicalIF":2.8,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43247277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
