The full degree of variety potentially demanded will not, in general, be supplied because scale economies (even to a small degree) mean that the potential welfare or revenue gain from greater variety must be balanced against the lower unit production costs with fewer variants. The economics of product variety consists essentially in analysing the effect of this balance in different situations, and comparing the degree of product variety for different market structures with each other and with the optimum. The survey commences with the work on market structures with single product firms (generalized monopolistic competition), tracing modern developments in both the Chamberlinian and Hotelling traditions. The latter has been particularly fruitful, due to the expansion of the original locational ideas into virtual spaces in product characteristics. The emphasis in recent work on product variety has been on multiproduct firms in both monopolistic and oligopolistic structures, including strategic market preemption. Although most work has been in a full information context, there have been advances in product variety under imperfect information (either by consumers to properties of the firms' products or firms as to consumers' demands). </jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382825893565247360","@type":"Researcher","foaf:name":[{"@value":"Kelvin Lancaster"}],"jpcoar:affiliationName":[{"@value":"Columbia University"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"07322399"},{"@type":"EISSN","@value":"1526548X"}],"prism:publicationName":[{"@value":"Marketing Science"}],"dc:publisher":[{"@value":"Institute for Operations Research and the Management Sciences (INFORMS)"}],"prism:publicationDate":"1990-08","prism:volume":"9","prism:number":"3","prism:startingPage":"189","prism:endingPage":"206"},"reviewed":"false","url":[{"@id":"https://pubsonline.informs.org/doi/pdf/10.1287/mksc.9.3.189"}],"createdAt":"2008-10-31","modifiedAt":"2023-04-02","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360002219549928192","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Estimating Optimal Product Variety of Firms"}]},{"@id":"https://cir.nii.ac.jp/crid/1360004232115591552","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Customization competition between branded firms: Continuous extension of product line from core product"}]},{"@id":"https://cir.nii.ac.jp/crid/1360004232204497280","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Planning and scheduling in the automotive industry: A comparison of industrial practice at German and Japanese makers"}]},{"@id":"https://cir.nii.ac.jp/crid/1360004232479118592","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Frugal innovation and design changes expanding the cost-performance frontier: A Schumpeterian approach"}]},{"@id":"https://cir.nii.ac.jp/crid/1360021390554584576","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Sequential product positioning and entry timing under differential costs in a continuous-time model"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567187784702592","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Organizational Inertia and Excessive Product Proliferation"}]},{"@id":"https://cir.nii.ac.jp/crid/1360848657045855616","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Product differentiation and entry timing in a continuous time spatial competition model"}]},{"@id":"https://cir.nii.ac.jp/crid/1360848657134595072","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Monozukuri capability to address product variety: A comparison between Japanese and German automotive makers"}]},{"@id":"https://cir.nii.ac.jp/crid/1360848660721278976","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"The Long Tail of the Auto Industry Life Cycle"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679088207744","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"PRICE COMPETITION AND SOCIAL WELFARE COMPARISONS BETWEEN LARGE-SCALE AND SMALL-SCALE RETAILERS"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1287/mksc.9.3.189"},{"@type":"CROSSREF","@value":"10.14441/eier.a2012002_references_DOI_4HUTTLSldA75kIa6Cw8D3QBKVN"},{"@type":"CROSSREF","@value":"10.1007/s10479-023-05665-z_references_DOI_4HUTTLSldA75kIa6Cw8D3QBKVN"},{"@type":"CROSSREF","@value":"10.1515/asia-2015-0055_references_DOI_4HUTTLSldA75kIa6Cw8D3QBKVN"},{"@type":"CROSSREF","@value":"10.1016/j.ijpe.2014.07.005_references_DOI_4HUTTLSldA75kIa6Cw8D3QBKVN"},{"@type":"CROSSREF","@value":"10.1016/j.ijpe.2013.02.026_references_DOI_4HUTTLSldA75kIa6Cw8D3QBKVN"},{"@type":"CROSSREF","@value":"10.1111/jpim.12076_references_DOI_4HUTTLSldA75kIa6Cw8D3QBKVN"},{"@type":"CROSSREF","@value":"10.1016/j.ejor.2012.10.001_references_DOI_4HUTTLSldA75kIa6Cw8D3QBKVN"},{"@type":"CROSSREF","@value":"10.1016/j.ejor.2015.06.049_references_DOI_4HUTTLSldA75kIa6Cw8D3QBKVN"},{"@type":"CROSSREF","@value":"10.15807/jorsj.61.40_references_DOI_4HUTTLSldA75kIa6Cw8D3QBKVN"},{"@type":"CROSSREF","@value":"10.1016/j.respol.2018.10.014_references_DOI_4HUTTLSldA75kIa6Cw8D3QBKVN"}]}
