Abstract(s)
O mercado de retalho está cheio de concorrência feroz e clientes cada vez mais exigentes. Esses são alguns dos fatores que levaram a uma crescente preocupação com a eficiência no setor do retalho. Esta dissertação aplica a metodologia Data Envelopment Analysis (DEA), seguindo uma orientação de output, para 34 lojas de uma empresa mundial do setor de retalho não-alimentar que opera em Portugal, a fim de avaliar a eficiência relativa das mesmas. Os resultados mostram que a maioria das lojas são tecnicamente ineficientes e devem aprender com as poucas consideradas eficientes. Também apresentam que muitas lojas não são eficientes do ponto de vista da escala, sendo que a maioria delas são demasiado grandes. O estudo ilustra a utilidade do DEA para avaliar a eficiência relativa das lojas de retalho dado o contexto do estudo.
The retail marketplace is packed with fearful competition and more and more demanding customers. These are some of the factors that lead to an ever-increasing preoccupation with efficiency in the retail sector. This dissertation applies the Data Envelopment Analysis (DEA) methodology, following an output orientation, to 34 stores of a non-food worldwide retail company operating in Portugal in order to assess their relative efficiency. The results show that most of the stores are technically inefficient and should learn from the few efficient ones. It also identifies that many stores are not scale efficient, being most of them too big. The study illustrates the usefulness of DEA to evaluate the relative efficiency of the retail stores given the context of the study.
