HEDONIC ANALYSIS OF CELL PHONES SOLD WITH POST-PAID SERVICE PLANS IN BRAZIL

The aim of this paper is to analyze the determining factors for the pricing of handsets sold with service plans, using the hedonic price method. This was undertaken by building a database comprising 48 handset models, under nine different service plans, over a period of 53 weeks in 2008, and resulted in 27 different attributes and a total number of nearly 300,000 data registers. The results suggest that the value of monthly subscriptions and calling minutes are important to explain the prices of handsets. Furthermore, both the physical volume and number of megapixels of a camera had an effect on the prices. The bigger the handset, the cheaper it becomes, and the more megapixels a camera phone has, the more expensive it becomes. Additionally, it was found that in 2008 Brazilian phone companies were subsidizing enabled data connection handsets.

O regime de metas de inflação no Brasil: uma análise empírica do IPCA

O regime monetário de metas de inflação é um padrão de conduta da política monetária que passou a ser utilizado por vários países a partir da década de 1990, dentre eles o Brasil, que adotou este modelo em 1999, após uma crise cambial. Com seu arcabouço teórico pautado nas premissas da teoria novo-clássica e tendo como principal característica o anúncio prévio de uma meta numérica para a inflação, este regime passou a ser adotado por países que buscavam alcançar a estabilidade de seus preços. O presente trabalho irá brevemente expor a base teórica e as características do referido regime. Porém, o foco principal será a discussão da utilização do IPCA (Índice de Preços ao Consumidor Amplo) pelo regime de metas como balizador da inflação no Brasil.

INFLUENCE OF DISCOUNT PRICE ANNOUNCEMENTS ON CONSUMER'S BEHAVIOR

The theoretical framework that underpins this research study is based on the Prospect Theory formulated by Kahneman and Tversky, and Thaler's Mental Accounting Theory. The research aims to evaluate the consumers' behavior when different patterns of discount are offered (in percentage and absolute value and for larger and smaller discounts). Two experiments were conducted to explore these patterns of behavior and the results that were obtained supported the view that the framing effect was a common occurrence. The patterns of choice of individuals in a sample were found to be different due to changes in the ways discounts were offered. This can be explained by the various ways of presenting discount rates that had an impact on the influence of purchase intentions, recommendations and quality perception.
