Zusammenfassung:

This chapter discusses the concept of Granger causality for panel datasets that are both wide (many individuals) and long (many time periods). Such datasets are obtained for instance when sets of countries are observed over the long run. In such settings, classical issues of time series econometrics, such as (non-)stationarity and (non-)causality, also arise. After a brief theoretical presentation of Granger causality, we provide a complete empirical application using publicly available data from the World Bank and Climate Watch. We investigate Granger causality between economic growth and CO emissions for a set of 130 countries observed over 41 years. The empirical exercise is conducted with the statistical software Stata and is fully reproducible; thanks to the code that is provided. All steps of the analysis are carefully explained and the results are intuitively presented.

Does official development assistance promote tourism demand for donor countries ? Evidence from Switzerland

Zusammenfassung:

This study estimates the effect of official development assistance (ODA) on tourism demand of recipient countries for donor countries. We analyzed a panel dataset of 15 recipient countries of Switzerland’s aid from 2005 to 2017, for which data are available. We used both tourist arrivals at lodging establishments, particularly hotels, in Switzerland and hotel nights as proxies for recipient countries’ tourism demand in Switzerland. Using a modified gravity model of trade for empirical testing, we found that an increase of every US$1000 ODA to recipient countries would generate 3.6 tourist arrivals and almost four hotel nights in the following year, after controlling for the effects of GDP and population of recipient countries, the exchange rate and the distance between recipient countries and Switzerland, and trade facilitators. We conclude that ODA generates a positive externality on donor countries, namely, that recipient countries incline to increase their imports from donor countries, at least partially in the form of inbound tourism in donor countries.

The pricing of specialty coffee :

a cross-sectional analysis

Proceedings of the 6th Wine & Hospitality Management Workshop

Zusammenfassung:

Research in agricultural economics has traditionally focused on coffee as a commodity, overlooking the complex specialty coffee market. Similar to fine beverages like wine, tea, and whisky, specialty coffee is characterized by high-end, differentiated products with substantial price variation. Despite its growing importance, research on specialty coffee pricing remains limited. This study addresses this gap by employing hedonic regression analysis on a large dataset to quantify the impact of various coffee attributes on pricing. The results show that the Specialty Coffee Association (SCA) score significantly boosts prices, while certification status has minimal effects. Some regions in Panama (Chiriquí), Hawaii (Kona), Yemen (Sanaa), and Colombia (Huila, Cauca, Quindío) command premium prices. Varietal analysis reveals that Geisha and SL28 coffees fetch the highest prices. The study further leverages expert opinions to deepen the analysis and assesses the influence of consumers from economically developed countries on specialty coffee prices.

Guests’ perceptions of circular economy practices in hotels :

reduce, reuse and recycle is not enough

Florent Girardin, Luciano Lopez

Proceedings of the APacCHRIE 2023 Conference

Link zur Konferenz

Zusammenfassung:

Circular economy (CE) practices aim to limit the negative impact of industries by reducing both the use of non-renewable resources and the wastes resulting from companies’ activities. In a hospitality context, hotels, restaurants and other companies can implement a range of practices with the intention to achieve a more circular business model. In this research, we conduct an online experiment to empirically test the effect of hotels’ CE practices on guests’ attitude and willingness to pay a price premium (WTP). We show that the “3Rs” CE practices, (Reduce, Reuse, Recycle) do not lead to higher WTP. By contrast, the CE practices that involve a “Rethink” or “Redesign” component of the hotel processes or infrastructure do in fact increase WTP. By using a mediation analysis, we also show that attitude towards the hotel mediates the effect of CE practices on WTP. Our research has concrete implications both for hotel owners and managers who wish to implement CE practices in their hotels and for academic researchers in hospitality.

Do hotels’ circular economy efforts really attract guests ?

Proceedings of the EMAC Annual Conference 2022

Link zur Konferenz

Zusammenfassung:

As one of the engines for economic development, the tourism and hospitality industries have many positive effects on trade and employment but may harm the environment given that their business models tend to be based on the linear economy as opposed to the circular economy (CE). In this context, our research empirically examines the effects of hotels’ specific CE practices on guests’ general attitude towards those hotels as well as their willingness to pay a price premium (WTP). We select the most relevant hotels’ CE practices from the literature and conduct a 2 (3 stars vs. 5 stars) X 7 (6 CE practices + control) between-subject experiment where respondents are exposed to a fictitious hotel website and asked to evaluate their attitude and WTP for that hotel. Our results first reveal that WTP is only affected by CE practices with a rethink or redesign dimension. Second, they show that CE practices do not have positive effects on guests’ attitude towards hotels and can even have negative effects for specific CE practices. Third, our results suggest that the hotel category (i.e. 3-star vs 5-star) does not impact the effect of CE practices on hotels’ guests attitude and WTP.

The impact of bilateral aid on the donor exports

empirical evidence for Switzerland

Proceedings of the 2019 Congress of the SSES

Link zur Konferenz

Zusammenfassung:

This paper estimates a structural econometric model to investigate the relationship between Swiss bilateral ODA and exports in the recipient countries based on a panel of 95 recipient countries over 51 years. More precisely, an augmented gravity model of trade is used to quantify the impact of Swiss bilateral official development assistance on its own bilateral exports to the recipient countries. Results point towards a return on aid through exports of 0.59 USD for each 1 USD donated in the short run (static model) and of up to 1.73 USD in the long run (dynamic model). These effects (magnitude and signiﬁcance) vary substantially when groups of recipient countries are formed on the basis of their geographical location or on the magnitude of bilateral aid or export flows they receive from Switzerland. In particular, return on ODA turns out to be statistically significant if ODA is directed toward countries to which Switzerland exports the least but donates the most or toward African or Asian countries (rather than to Latin American or European countries). Thus, despite the fact that Switzerland is considered as one of the most altruistic donors (it donates a high share of untied aid), bilateral aid has still a considerable economic impact on Switzerland through exports.
