The impact of information and communication technologies: an insight at micro-level on one Italian region
No full textIt has been debated as to whether European countries and Italy itself have yet shared in the US productivity growth driven by the information and communication technology
(ICT) revolution. This paper investigates the extent of ICT diffusion in manufacturing firms from an Italian region and its effect on performance at a micro-level from 2002 to
2008. It contributes to previous findings from three perspectives. First, it investigates the causal link between ICT adoption and productivity; second, it considers the distributional effect of ICT by measuring its impact on firms with different levels of efficiency and productivity; and third, it takes into account the important distinction between productive ICT embedded in machinery and capital equipment and integrating ICT acquired as licenses or know-how as external disembodied technology, with the basic purpose being to identify the channels through which ICT may work for different types of firms. The main findings are that (i) a wide dissemination of ICT is not exploited to its full potential;
(ii) the ICT adoption has produced higher growth in technical efficiency for adopter firms than for the non-adopter firms, but slower growth in productivity, so supporting
the productive paradox at the firm level; and (iii) different types of ICTs have had opposite impact among adopter firms – the adoption of ICTs as productive embodied
technologies has accelerated the performance growth of firms with lower growth rates, while the adoption of ICTs of organisational type has increased their delay in efficiency
and productivity with respect to the firms with higher growth rates

The effect of liking on the memorial response to advertising: the case of small cars
No full textIn marketing literature there is actually very poor evidence of how ad liking works to build its impact on memorial response to ad pressure. This study investigates the problem of the existence of carryover effects of ad liking on recall, by modelling the dynamic patterns of recall, ad pressure and liking by means of the specification of an augmented Koyck-type model and provides a methodology for assessing ad likeability ex post effectiveness on recall variables. The analysis is carried out for the Italian market of small automobiles. Main empirical findings highlight that carryover effects of ad liking can be detected, ene if not systematically. For practitioners the most important implication is that likeability always play a key role in building consumer attention
On the finite representation of linear group equivariant operators via permutant measures
No full textRecent advances in machine learning have highlighted the importance of using group equivariant non-expansive operators for building neural networks in a more transparent and interpretable way. An operator is called equivariant with respect to a group if the action of the group commutes with the operator. Group equivariant non-expansive operators can be seen as multi-level components that can be joined and connected in order to form neural networks by applying the operations of chaining, convex combination and direct product. In this paper we prove that each linear G-equivariant non-expansive operator (GENEO) can be produced by a weighted summation associated with a suitable permutant measure, provided that the group G transitively acts on a finite signal domain. This result is based on the Birkhoff–von Neumann decomposition of doubly stochastic matrices and some well known facts in group theory. Our theorem makes available a new method to build all linear GENEOs with respect to a transitively acting group in the finite setting. This work is part of the research devoted to develop a good mathematical theory of GENEOs, seen as relevant components in machine learning
The effects of marketing activities on fast moving consumer good purchases: the case of yoghurt Italian market
No full textThis paper examines whether sales promotions effectiveness depends upon the consumer’s brand loyalty and her buying behaviour and whether consumer’s behavioural characteristics in term of purchase frequency and level affect the response to promotional activities and moderate the effect of brand loyalty during the consumer choice process. Different specifications for the utility function, exploiting information on selling price, promotional activities such as displays usage, ad features in the store, 3x2 and discount, and differently brand loyalty measures have been estimated into a discrete choice framework, that is into the rational brand choice paradigm, paying attention to their effects on individuals’ probabilities to choose the specific brand during each purchase occasion. The application is run on a ACNielsen dataset of Italian households consumer panel, observed to buy at least two yoghurt packages during a year, matched to store panel data with respect to quantities, prices and promotions
Il classicismo onirico di Armando Brasini nell’E42: l’Istituto Forestale “A. Mussolini”
No full textIl contributo analizza un'opera romana dell'architetto Armando Brasini, tra i più noti e attivi del periodo fascista, ovvero il progetto per l'Istituto Forestale dedicato al fratello del Duce da realizzare per l'Esposizione Romana del 1942, mai completato, inquadrandolo nella produzione architettonica romana e italiana tra le due guerre
