    Fact or artefact: the impact of measurement errors on the farm-productivity relationship

    No full text
    This paper revisits the role of land measurement error in the inverse farm size and productivity relationship (IR). By making use of data from a nationally representative household survey from Uganda, in which self-reported land size information is complemented by plot measurements collected using Global Position System (GPS) devices we reject the hypothesis that IR may just be a statistical artifact linked to problems with land measurement error. In particular, we explore: (i) what are the determinants of the bias in land measurement, (ii) how this bias varies systematically with plot size and landholding, and (iii) the extent to which land measurement error affects the relative advantage of smallholders implied by the IR. Our findings indicate that using an improved measure of land size strengthens the evidence in support of the existence of the IR

    Si tratta dell'introduzione ad una serie di profili di protagonisti della storia dell'arte e del patrimonio nel decennio Settanta. In coincidenza con la fase istituzionale destinata a realizzare il progetto regionale, la questione dei beni culturali e del territorio assume una diversa rilevanza, uscendo dagli ambiti esclusivamente specialistici e creando un'opinione pubblica più vasta
