그들은 또한 수익 효과를 포함하기 위해 확장 될 수 있습니다. 나는 이러한 결과를 증명하고 단지 시장 수준의 데이터를 사용하여이 클래스의 모델을 구조적으로 추정하는 방법을 보여줍니다. 소비자 선호도의 분포는 단지 집계 용어로 모서리 솔루션을 규율하여 회복됩니다.이 접근 방식은 Berry, Levinsohn, and Pakes (1995) [BLP]의 동일한 부를 허용하고 선형 수요의 분석 및 계산 장점을 유지하면서 : 그것은 외관적으로 시장 규모를 고정 할 필요가 없습니다, 선택 세트에서 이질성을 허용하고, 다른 응용 프로그램의 다양한 범위 사이에서 유연한 대체 매트릭스에 결과.

Aggregate linear demand systems can be micro-founded by a population of heterogeneous consumers making discrete choices. They can also be extended to incorporate income effects. I prove these results and show how to structurally estimate this class of models using only market-level data. The distribution of consumer preferences is recovered by disciplining the corner solutions with aggregate terms only. This approach allows for the same richness of Berry, Levinsohn, and Pakes (1995) [BLP] while retaining the analytical and computational advantages of linear demand: it does not require exogenously fixing market size, allows for heterogeneity in choice sets, and results in a flexible substitution matrix which varies endogenously as different consumers enter/exit the market. The discrete-choice microfoundation facilitates welfare analysis and the flexible measurement of markups an cost pass-throughs, among a wide range of other applications.
