Estimación de elasticidades de demanda de bienes y servicios en Perú mediante los métodos AIDS y QUAIDS[Estimating demand elasticities of goods and services in Peru using the AIDS and QUAIDS methods]

The demand behavior of the different goods and services is a key component that shapes the structure of an economy, and its analysis is economic policies, such as taxation and promotion of productive development. Within the many demand systems posed in the theoretical and empirical literature, the almost ideal demand systems (AIDS and QUAIDS) have properties consistent with the maximization of utility according to the consumer's neoclassical theory. In this paper, we estimate price elasticities of demand, cross price and income are estimated for large groups of goods and services in Peru from 2004 to 2014, using AIDS and QUAIDS models, based on data from household surveys, using the AIDS and QUAIDS. It is found that the values of price elasticities of demand are consistent with the literature. Likewise, it is determined that the services of care, health conservation, transportation and communications, leisure, entertainment, cultural services, and education and other services constitute luxury goods, although there is heterogeneity in the results when the analysis is done at a higher level of disaggregation.
