Airbnb and the housing market in Italy. Evidence from six Cities
Full text linkWe study how the growth of Airbnb has affected the housing market in six important Italian
cities – Milan, Turin, Venice, Florence, Rome, and Naples. These cities differ in terms of tourist
attractiveness, seasonality of visitors, business and industry vocation, and morphological constraints
to their boundaries. Our empirical strategy accounts for omitted variable bias as well as for reverse
causality. We apply an instrumental variable approach by using two alternative measures of cityspecific “touristiness” that vary within cities, according to the relevance of touristic attractions as
reviewed by Tripadvisor and Lonely Planet, and over time, based on a measure of Airbnb popularity
as proxied by GoogleTrends.
We find that Airbnb density leads to increases in rents and sale prices, but the effect varies
greatly across cities and, even more, within cities (centre and suburbs). For some cities this impact is
virtually non-existent, even in the town centre; for some is weak or even negative, but for others is
sizeable. However, the overall quantitative effect remains modest, thus suggesting that attempts to
regulate home-sharing and short-term rentals (from this point of view) have to be calibrated with much
attention
The uneven effect of Airbnb on the housing market. Evidence across and within Italian cities
Full text linkWe investigate if Airbnb diffusion affects residential property values differently across and within cities leveraging the heterogeneity of five Italian cities in terms of tourist attractiveness, local housing markets and socio-economic conditions. We
find that Airbnb density growth leads to increases in house prices in all cities. Within-city, the impact is positive both in centers and in suburbs in more touristic towns, but only in center in the others. Moreover, Airbnb may increase or decrease the center-periphery price gap. Our results suggest that the different impact of Airbnb on housing sub-markets is driven by local disparity conditions
Energy systems integration : implications for public policy
Full text linkPublished online: August 2020Energy Systems Integration (ESI) is an emerging paradigm and at the centre of the EU energy debate. ESI takes a holistic view of the electricity, gas, and heat sectors to deliver a clean, reliable, and affordable energy system. By using the synergies within and between sectors, ESI aims to increase flexibility in the energy system, maximise the integration of renewable energy and distributed generation, and reduce environmental impact. While ESI-enabling technologies have been studied from a technical perspective, the economic, regulatory, and policy dimensions of ESI are yet to be analysed in depth. This paper discusses ESI in a multi-step approach. We first focus on the economics of ESI-enabling technologies. Then we briefly discuss how the EU national regulators incentivise their adoption. Major economic and policy barriers to ESI are identified and policy solutions to overcome these barriers are proposed. We conclude that current regulatory frameworks in the EU do not sufficiently stimulate ESI investments and only through proper design of incentives ESI can be adopted
The impact of regulation on the airport industry
No full textIn this chapter, we discuss the role of airport regulation and its potential impact on the airport manager’s performance. The aim is to provide a framework that can be useful to assess the effect of a change in the regulatory framework in a specific country. With this goal, we apply our analysis to the Italian airport industry. In 2013, a new institutional framework was introduced with the establishment of an independent regulator, the Italian transport regulation authority. In 2014, the Authority modified the regulatory mechanism by introducing a negotiation procedure between airport managers and airline users, in application of the EU Directive 2009/12/EC, as well as new pricing schemes and incentives to improve efficiency. Those regulatory changes are not a singleton in Europe but, on the contrary, are in line with most of the EU countries’ experiences in airport regulation. We assess the impact this regulatory change has had on the average costs of affected airport. Our analysis suggests that the average costs of airports that adopted the new regulatory framework significantly decline as a result of the change in regulation compared to the performance of airports which do not apply the new regulatory approach yet. All in all, results suggest that the new regulatory approach has increased the overall efficiency of the Italian airport system
User data and endogenous entry in online markets
Full text linkWe investigate how the presence of a Data Broker (DB), who sells consumer data to downstream firms, affects firm entry and competition in a horizontally differentiated oligopoly market, in which data allow firms to price discriminate. The DB chooses the price and amount of data sold to each firm. We show that the data sale by theDB reduces excessive market entry, as the competition induced by personalized prices exerts a downward pressure on prices and profits. The data-induced entry barrier and resulting weakened competition dominates the pro-competitive effect of personalized prices. Consequently, while the DB’s presence might alleviate excessive market entry, it also diminishes consumer surplus
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
