Good vs. bad characteristics in vertical differentiation
No full textWe consider a vertically differentiated duopoly where product quality is defined as the combination of N characteristics. Good (respectively, bad) characteristics are those which increase (decrease) utility with respect to the status quo. We prove that maximum (minimum) differentiation obtains along all characteristics respect to which marginal profits are positive (negative)
Bidimensional vertical differentiation
No full textIn markets where product quality is important, more than one characteristic is usually necessary for producers to define product quality. Standard theory maintains that: (i) in a duopoly there will be a quality leader no matter wether the product can incorporate one or two vertical attributes; (ii) differentiation pertains only to one attribute. By contrast, in our set-up, there are also equilibria where the quality leader is better in two attributes, and others where there is cross leadership, namely a situation where each firm designs a product to dominate the other in one characteristic. Applications to Minimum Quality Standards and tax (subsidy) on quality products are sketched, showing spill-over effects from one to the other quality dimension
Give to Ceasar what is Ceasar's. Or, give to Launhardt what we are used to think is Bertrand's

Confronto tra indicatori diversi (ossido di cromo e ceneri acido insolubili) per la determinazione della digeribilità apparente nei suinetti
No full textLa ricerca è stata condotta utilizzando 25 coppie di suinetti dell'età di due mesi, sottoposti a prelievo rectal grab-sampling due volte al giorno: le ceneri acido-insolubili (AIA) si sono rivelate comparabili, quale indicatore di digeribilità in vivo, all'ossido di cromo / The comparison between different markers (chromic oxide and acid-insoluble ash) for the determination of apparent digestibility in vivo was studied on 25 couples of piglets about two months old using rectal grab-sampling method for the collection of faeces: the values obtained by using HCl 2N are, on average, very similar to those obtained with chromic oxide
Aggiunta di aminoacidi ed oligopeptidi a diete per suinetti. Nota 2. Effetti sulla digeribilità apparente di alcuni principi alimentari
No full textLe prove di digeribilità sono state condotte su 15 suinetti svezzati precocemente (21 giorni circa) sottoposti a raccolta grab-sampling delle feci, utilizzando come indicatore il sesquiossido di cromo / The apparent digestibility coefficients of some nutrients related to the addition of small quantities of amino acid and oligopeptide pools to balanced diets were determined on 15 piglets weaned 21 days old, by means of grab-sampling of the faeces and chromic oxide as indicator
