Increase in transmitted resistance to non-nucleoside reverse transcriptase inhibitors among newly diagnosed HIV-1 infections in Europe
2014
Background: One out of ten newly diagnosed patients in Europe was infected with a virus carrying a drug resistant mutation. We analysed the patterns over time for transmitted drug resistance mutations (TDRM) using data from the European Spread program.Methods: Clinical, epidemiological and virological data from 4317 patients newly diagnosed with HIV-1 infection between 2002 and 2007 were analysed. Patients were enrolled using a pre-defined sampling strategy.Results: The overall prevalence of TDRM in this period was 8.9% (95% CI: 8.1-9.8). Interestingly, significant changes over time in TDRM caused by the different drug classes were found. Whereas nucleoside resistance mutations remained con…
Demand for and Pricing of Mobile Internet: Evidence from a Real-World Pricing Experiment
2006
Commercialization of innovations frequently stumbles. A prominent recent example are the early (i.e. pre3G)mobile phone-enabled Internet services, whose European takeup was slower than expected. To determine why, we build a structural model of demand for such services and estimate it using consumerlevel panel data from a real world pricing experiment. The experiment allows for a decomposition of the number of wireless connections into the number of needs instances where a consumer would establish a connection if the price were zero and the conditional probability of establishing a connection. We find that needs were plenty and potential consumer surplus several magnitudes higher than that a…
Sustaining Canadian marine biodiversity: Policy and statutory progress
2020
A 2012 Expert Panel Report on marine biodiversity by the Royal Society of Canada (RSC) concluded that Canada faced significant challenges in achieving sustainable fisheries, regulating aquaculture, and accounting for climate change. Relative to many countries, progress by Canada in fulfilling international obligations to sustain biodiversity was deemed poor. To track progress by Canada since 2012, the RSC struck a committee to track policy and statutory developments on matters pertaining to marine biodiversity and to identify policy challenges, and leading options for implementation that lie ahead. The report by the Policy Briefing Committee is presented here. It concluded that Canada has …
Is the sustainability profile of FinTech companies a key driver of their value?
2022
[EN] The digitisation process is affecting all markets and raising consumer awareness about companies' sustainable behaviour. This work studies the effect of the sustainability profile of FinTech companies on the firm (market value and book value) as the factors that add value to investors and motivate their evolution in markets are still unknown. Using the KBW and Nasdaq FinTech Indices, and the NASDAQ Insurance Index (IXIS), we composed a panel of 95 companies over a 10-year period (2010-2019) with economic-financial variables and data about green certificates and sustainability indices. The applied methodology is based on dynamic (GMM-SYS) and static (PCSE) panel data models. Our results…
The Export-Productivity Link in Brazilian Manufacturing Firms
2015
This paper explores the link between exports and total factor productivity in Brazilian manufacturing firms over the period 2000–08. The Brazilian experience is instructive, as it is a case of an economy that expanded aggregate exports significantly, but with stagnant aggregate growth in total factor productivity. The paper first estimates firm-level total factor productivity under alternative assumptions (exogenous and endogenous law of motion for productivity) following a GMM procedure. In turn, the analysis uses stochastic dominance techniques to assess whether the ex ante most productive firms are those that start exporting (self-selection hypothesis). Finally, the paper tests whether e…
Corporate governance and financial performance: The role of ownership and board structure
2018
Abstract This study examines how corporate governance and ownership structure relate to the financial performance of firms. We estimated this relationship using fsQCA. We enhanced our analysis using complementary linear and non-linear multiple regression analysis. The panel data used in this study covered 1207 companies from 59 countries across 19 sectors for the period 2013 to 2015. The study makes two main contributions. First, the multiple empirical techniques employed in this study offer a broader approach to the empirical analysis of financial performance. Second, the study aids our understanding of the role of corporate governance and ownership in the financial performance of firms.
Trade credit and determinants of profitability in Europe. The case of the agri-food industry
2018
Abstract The objective of this paper is to analyse the effect that trade credit has on the determinants of profitability during the crisis period in Europe. We use panel data for a total of 24,177 European agri-food companies from 2010 to 2014. Among our main contributions, we highlight that we isolate the sector effect and study the country effect by separating the different policies and customs with respect to the granting of trade credit. The results confirm, in general, that trade credit affects profitability depending on the country and the characteristics of size, specificity, market power or reputation.
Developing a blog trust scale via an international Delphi panel
2020
Abstract Although trust is one of the most widespread and studied constructs in marketing and management, its definition, versatility and different application areas may have fostered a certain dispersion when measuring this concept. Despite the increasing importance of blogs, specific scales for, and measures of, trust have not been considered in the literature. This paper proposes a scale to measure online trust in the blog domain (Blog Trust Scale, BTS) through the development of an international Delphi panel consisting of 14 experts from 5 different countries. As a result, we have developed a solid measurement instrument of online trust in blogs, composed of 12 items and tested in four …
Quantile regression for the FDI gravity equation
2015
Abstract Firm-level heterogeneity shapes foreign direct investment (FDI) flows, whereby a few firms are responsible for most of the world's FDI. Aggregate outcomes of FDI are highly skewed, and the estimates of FDI's antecedents vary largely depending on FDI level. The incidence of individual firms, however, varies across FDI's quantiles. To study the individual firms' effect on FDI flows, this study develops a quantile regression method for bilateral FDI panel data. This study estimates the differential incidence of individual firm-level projects on aggregate flows among 161 countries from 2003 to 2012. Results suggest that FDI's determinants vary across quantiles. In particular, the effec…
The impact of corruption on sport demand
2020
PurposeThe article presents an empirical analysis that evaluates the effects of a systemic corruption scandal on the demand in the short and the long run. In 2006, the Calciopoli scandal uncovered the match rigging in the Italian soccer first division. The exemplary sportive sanction of relegating the primary culprit to the second division imposed further negative externalities on the other clubs. Should we prefer the sportive sanction on the team or the monetary fines for the club?Design/methodology/approachWe estimated two log-linear models of the demand side (stadium attendance) using a fixed effect estimator, on two panel data set made of all the Italian soccer clubs in the first and se…
