US deficit sustainability revisited: A multiple structural change approach

2008

In this article we re-examine the long-run sustainability of US budget deficits, using Bai and Perron's multiple structural change approach. While the deficit would have been weakly sustainable over the full sample (1947:1–2005:3), strong sustainability would appear only between January 1982 and February 1996.

Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes

2022

Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021.

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…

Eiropas Savienības politika Austrumu partnerības attīstībai: Austrumu partnerības samitu loma.

2015

Maģistra darbs „Eiropas Savienības politika Austrumu partnerības attīstībai: Austrumu partnerības samitu loma” ir veltīts Austrumu partnerības attīstības izpētei, ko veicinājusi Eiropas Savienības Kaimiņvalstu politika. Austrumu partnerība ir viena no ES ārējās politikas prioritātēm, tāpēc tās ietvaros dažādās formās tiek stiprināta sadarbība ar Austrumu partnerības valstīm, lai caur savstarpēju ekonomisku un politisku attiecību veidošanu ES nodrošinātu ekonomisku, politisku stabilitāti un mieru kaimiņvalstīs, kā arī ES robežu stiprināšanu. Viens no augstākā politiskā līmeņa daudzpusējās sadarbības formātiem ir Austrumu partnerības samiti, kuru laikā tiek izvērtēti Austrumu partnerības sasn…

Analytical Model for wideband THz sources and detectors based on Optical Rectification and Electro-Optic Sampling

2013

An analytical model describing a laser based set-up for wideband THz generation and detection is presented. Particular attention is focused on the main broadband phenomena, which occur when THz radiations have to be handled.

Cryogenic 35GHz pulse ENDOR probehead accommodating large sample sizes: Performance and applications.

2009

The construction and performance of a cryogenic 35GHz pulse electron nuclear double resonance (ENDOR) probehead for large samples is presented. The resonator is based on a rectangular TE(102) cavity in which the radio frequency (rf) B(2)-field is generated by a two turn saddle ENDOR coil crossing the resonator along the sample axis with minimal distance to the sample tube. An rf power efficiency factor is used to define the B(2)-field strength per square-root of the transmitted rf power over the frequency range 2-180MHz. The distributions of the microwave B(1)- and E(1)-field, and the rf B(2)-field are investigated by electromagnetic field calculations. All dielectrics, the sample tube, and…

The Italian adaptation and validation of the Adult Sibling Relationship Questionnaire (ASRQ) in Italian emerging adults

2013

The aims of the present study were to provide a contribution to the validation of the Adult Sibling Relationship Questionnaire (ASRQ) (Stocker, Lanthier, & Furman, 1997) with a population of Italian emerging adults. The ASRQ measures individuals’ current perceptions of their own behaviour and feelings toward their sibling, as well as their perceptions of their sibling’s behaviour and feelings toward him or her by assessing fourteen fundamental dimensions (Intimacy; Affection; Emotional Support; Instrumental Support; Knowledge; Similarity; Admiration; Acceptance; Dominance; Competition; Antagonism; Quarrelling; Maternal Rivalry; and Paternal Rivalry), combined in order to form three macro-di…

Sharing economy and dynamic pricing: Is the impact of Airbnb on the hotel industry time-dependent?

2021

Abstract Prior literature has reported significant price and revenue reductions in the hotel industry due to the emergence of Airbnb. Other studies have documented that hotels' price reactions to the penetration of Airbnb depend on their service level, e.g., low/medium-end versus high end. Relying on a large sample from the Italian market, we contribute by showing that the effect of Airbnb on hotels' price decisions does not only depend on incumbents’ quality level, but also on the difference between booking and check-in time. That is, the effect of the penetration of Airbnb on hotels' dynamic price decisions varies over time depending on the core segment hotels target.
