Innovation Dynamics in Space: Local Actors and Local Factors

1997

This paper addresses the issue of technogenesis and its geographical pattern. It aims to offer both a general analysis framework and a test on innovation data from several European cities. This framework is mainly built on the product life-cycle and the incubation approach. On the basis of this framework, it is argued that the phases of an industrial life-cycle have several firm-specific effects. First, these phases influence innovativeness and thus profit levels, output and employment of firms in a spatially distinct way. Second, the phases of the life-cycle mirror the importance of local factors for innovations, and third, they affect strategic decisions of firms, inter alia by influencin…

Sharing economy and incumbents' pricing strategy: The impact of Airbnb on the hospitality industry

2019

Abstract In this paper, we examine how the emergence of sharing economy platforms influences incumbents' price responses. Grounding on the literature on price reactions to new entrants and on the unique characteristics of the sharing economy, we argue that the effect of the penetration of the sharing economy on incumbents' prices is not straightforward, and actually depends on the type of incumbents as well as certain product/service offer characteristics. Indeed, relying on a large sample of hotel price offerings from the Italian market, we find that the effect of the growing relevance of the sharing economy (exemplified by Airbnb) on incumbents' prices depends on the type of incumbents (l…

La filiera siciliana della pasta: un'applicazione della netchain analysis

2016

The system of Sicilian durum wheat is facing, as indeed is happening to the entire food system, the evolution of consumption patterns toward higher quality requirements: health-wise, primarily, but also including some intangible requirements. Recent acquisitions in the field of healthy food, have called attention to some specific characteristics of Sicilian durum wheat. The durum wheat sector represents a major landmark for regional agriculture, being by far the most widespread arable crop in Sicily; a crop that, over the past 30 years, has evolved considerably, due to the impact of EU regulations. Currently, the whole Sicilian cereal-pasta chain shows shortcomings in organization and size,…

Do commodity assets hedge uncertainties? What we learn from the recent turbulence period?

2022

AbstractThis study analyses the impact of different uncertainties on commodity markets to assess commodity markets' hedging or safe-haven properties. Using time-varying dynamic conditional correlation and wavelet-based Quantile-on-Quantile regression models, our findings show that, both before and during the COVID-19 crisis, soybeans and clean energy stocks offer strong safe-haven opportunities against cryptocurrency price uncertainty and geopolitical risks (GPR). Soybean markets weakly hedge cryptocurrency policy uncertainty, US economic policy uncertainty, and crude oil volatility. In addition, GSCI commodity and crude oil also offer a weak safe-haven property against cryptocurrency uncer…

Autoencoders and Recurrent Neural Networks Based Algorithm for Prognosis of Bearing Life

2018

Bearings are one of the most critical components in electric motors, gearboxes and wind turbines. Therefore, bearing fault detection and prognosis of remaining useful life are important to prevent productivity losses. In this study, a novel method is proposed for prognosis of bearing life using an autoencoder and recurrent neural networks-based prediction algorithm. Promising results have been obtained from the experimental data. A monotonic upward trend of the produced health indicator is obtained for all test cases, being one of critical indicators of a proper prognosis. The remaining useful life estimation is moderately accurate under a limited data.

Viral marketing through e-mail: the link company-consumer

2013

Purpose – The purpose of this paper is to identify the antecedents that may determine the opening of e-mails from companies that endeavour to promote their products, and what may motivate individuals to forward such messages to others. Design/methodology/approach – The paper presents exploratory research to approach the nature of the viral process and descriptive research for testing the proposed hypotheses. Findings – The opening of an e-mail is determined by the value that an individual may perceive that the message might contain. Forwarding of the message is determined by its opening, and by the individual's perception about the value of the message it may provide to others, besides the…

Quality management in the public sector accounting department - (un)avoidable quality costs and unlikely financial impacts

2017

This paper investigates the nature of quality costs and the likelihood of their having financial impacts in the public sector. An illustrative quality development case project in an accounting department of a Finnish city administration is presented. The empirical data includes answers to a qualitative project question sheet, workshop material and participative observation. Quality problems are classified according to their quality cost category and the extent to which they are avoidable. Some of the quality costs proved unavoidable and some are likely to lack financial impact, exhibiting sticky cost behaviour. The study indicates that certain prevention and appraisal costs in the public se…

Business strategy in new high‐tech ventures: an empirical analysis

1999

The aim of this study is to determine the existence of specific and unique features characterising markets, activities and customers in at least two of the most representative high technology sectors nowadays, the microelectronics/software industry and the biotechnology/biomedical industry. Cross‐Tabs statistical method has been used to analyze the data collected from the sample made up by 18 high‐tech American firms. One of the major findings of this study is that the business strategy will hold better prospects in those high‐tech firms benefiting from a higher technological excellence, having spent longer time in developing and launching their products, being able to keep longer the novel…

Information technology and logistics quality: a basis for companies' segmentation

2010

The use of information technology (IT) is substantially modifying business areas in companies, and logistics is no exception. Moreover, the incorporation of concepts like 'Quality' has been truly revolutionary. This paper focuses on the study of these variables and aims to investigate their ability to group companies. To attain this goal we have carried out an empirical research in the Spanish market. The study carried out shows that companies can be grouped according to the level of introduction and use of IT and their perceptions on the level of service quality provided by the supplier.
