Maz'ya-Shaposhnikova formula in Magnetic Fractional Orlicz-Sobolev spaces

In this note we prove the validity of the Maz'ya-Shaposhnikova formula in magnetic fractional Orlicz-Sobolev spaces. This complements a previous study of the limit as $s \uparrow 1$ performed by the second author in [21]

Tourism expenditure of EU-27 regions under the global economic crisis

This study focuses on the underpinnings of the households’ tourism expenditure decisions during the global economic crisis in 2009. In particular, this study tests if during an economic crisis, decisions on tourism expenditure depend on climate conditions of the place of origin, GDP and GDP growth, among other well-known determinants. It should be noted that cutback decisions on tourism expenditure are not independent of destination choice, and for that reason the model requires the estimation of both decisions simultaneously. The methodology proposed in this paper represents a new way of analyzing the impacts of an economic crisis on tourism expenditure. Two levels of analysis can be considered. On the one hand, macroeconomic data of tourism expenditure is usually explored. On the other hand, the microeconomic analysis of the household and regional variables of their environment that may enrich the analysis. If the econometric model takes into account all these variables simultaneously, then the linkage between GDP changes and tourists´ behavior is enriched and it may be estimated more accurately. As far as we know, this paper is the first study that models the cutback decision on tourism expenditure. Modeling such decision is a challenge because it is not independent of the destination choice. For instance, households that travel domestically may not be as sensitive to the crisis as those who travel abroad. For this purpose, the econometric model employed is a simultaneous system of cutback decision and destination choice. More precisely, Simultaneous Semi-Ordered Bivariate Probit has proved to be the most useful econometric model for the estimation because it deals with the simultaneity of the cutback and destination choice decisions as well as the endogeneity. This research has proved that during an economic crisis, households react cutting back their tourism expenditure depending on GDP, GDP growth, and climate in their place of origin. In that sense, there are marked differences between North-European and Mediterranean regions. It is interesting to note that regions with bad climate are less likely to cut back than those households located in regions with good climate.Universidad de Málaga.

Impacts of Trade Liberalization on Poverty and Inequality in Argentina

Using the most recent estimates of agricultural price distortions, this chapter studies the economic, poverty, and income inequality impacts of both global and domestic trade reform in Argentina, with a special focus on export taxes. Argentina offers an interesting case study as the only large agricultural exporter that has, at many points in its history, applied export taxes to several of its agricultural products. The chapter combines results from a global economy-wide model (World Bank’s Linkage model), a national CGE model, and microsimulations. The results suggest that liberalization of world trade (including subsidies and import taxes, but not export taxes), both for agricultural and non-agricultural goods, reduces poverty and inequality in Argentina. However, if only agricultural goods are included, indicators for poverty and inequality do not improve and even deteriorate somewhat. This is particularly the case if export taxes are eliminated. The chapter discusses the possible reasons for those results, offers some caveats, and suggests some lines for further research.Distorted incentives, agricultural and trade policy reforms, national agricultural development, Agricultural and Food Policy, International Relations/Trade, F13, F14, Q17, Q18,

Warm-Intermediate inflationary universe model in braneworld cosmologies

Warm-intermediate inflationary universe models in the context of braneworld cosmologies, are studied. This study is done in the weak and strong dissipative regimes. We find that, the scalar potentials and dissipation coefficients in terms of the scalar field, evolves as type-power-law and powers of logarithms, respectively. General conditions required for these models to be realizable are derived and discussed. We also study the scalar and tensor perturbations for each regime. We use recent astronomical observations to constraint the parameters appearing in the braneworld models.Comment: 19 pages, 2 figures. Published in Eur. Phys. J.

Quantifying the impact of airlines exit in tourism destinations. The cases of Monarch and Thomas Cook

We analyze the impact on tourists’ arrivals after the bankruptcies of Monarch Airlines and Thomas Cook. It draws on arrivals from the UK to Canary Islands and it employs a univariate and multivariate structural time series with level interventions. More interestingly, after Monarch exit, the policymakers applied a laissez faire strategy, which resulted in a 93.04% net loss of their level of traffic in Tenerife. However, after Thomas Cook exit, the policymakers intervened in the market proposing incentives to the incumbent airlines to cover the loss. It resulted in a 34.72% net loss of Thomas Cook level of traffic. Moreover, we provide details about the redistribution of the traffic among the incumbent airlines that diminished the net loss of passengers

Maz'ya-Shaposhnikova formula in magnetic fractional Orlicz–Sobolev spaces

In this note we prove the validity of the Maz'ya-Shaposhnikova formula in magnetic fractional Orlicz-Sobolev spaces. This complements a previous asymptotic study of the limit as s ↑ 1 performed by the second author in (Studia Mathematica (2020)).Fil: Maione, Alberto.

Tourism expenditure under the global economic crisis: the role of climate in the place of residence

Tourists from different European regions have reacted heterogeneously during the Global Economic Crisis. Such variability is due to different preferences and willingness to pay for tourism. This paper explores the underpinnings behind such heterogeneity. Regional variables and household socioeconomic variables are gathered to understand tourists' expenditure cutback decision. Since the cutback decision is not independent of the destination choice, a Simultaneous Semi-Ordered Bivariate Probit model is specified, which deals with the simultaneous estimation of both decisions and endogeneity. Post-estimation results are based on GIS, contours and non-parametric analysis. They prove that during an economic crisis, tourists' cutback decisions on tourism expenditure depend on climate conditions of the place of origin, GDP and GDP growth.Universidad de Málaga.

Estimating the spatial and time decay impacts of a local event

This paper studies the spatial and temporal decay impacts of a local event on tourism accommodation in a region. The results show that the day of the event, the number of occupied rooms, ADR and revenue reach a marked peak. Moreover, it shows the presence of a time decay impact on revenue, which is asymmetric in favour of the days before the event. A spatial panel data regression method has been employed. The case study concerns Ironman Triathlon event and its impact on the Airbnb listings in the Spanish region of Vitoria-Gasteiz in 2019
