Aim of study: This study aims to analyse how psychological factors related to the Covid-19 lockdown affected the frequency of wine consumption among Iberian consumers.Area of study: To achieve this goal, we used data collected from an online survey in Europe comprising 4489 observations from Portuguese and Spanish samples.Material and methods: Using an ordered probit model, we analysed the wine consumption frequency as a function of a set of explanatory variables related to psychological factors, sociodemographic variables, consumption characterisation and channels of trade variables.Main results: The identification of the hedonic nature of wine consumption explains the increase in frequency, while the negative feelings associated with the lockdown and health concerns are not relevant, which implies a different effect on consumption than in the case of other disasters. Consumer loyalty before the lockdown and the role that technology has played in explaining the frequency of consumption in the form of apps, online purchasing and digital drinks opens up a new horizon in the study of consumer behaviour.Research highlights: Although econometrically different, the impact of the Covid-19 crisis tend to be felt similarly among the Iberian countries. The effects of psychological impacts related to feelings of Covid-19 of the lockdown does not show impact in wine consumption behaviour. The consumer background and behavioural attitude towards wine explain most changes in consumption patterns
Export activities have become crucial to firms’ competitiveness, with determinants of export performance being a challenging field of research, since there is no consensus regarding the explained and explanatory variables or on the econometric methods to be used. Using a panel data of Portuguese wine firms, this paper aims to contribute to this debate, combining both resource- and institutional-based views of the firm. This paper tries to overcome the methodological hurdle, addressing sample selection issues and considering the fractional response nature of export performance. Given the pros and cons of each econometric approach, the Heckman selection model, the fractional probit model and the two-part fractional response model are estimated, and the results compared. From a public policy perspective, the results show that policies that promote wine firm size, labor productivity and wine promotion in third countries have a positive impact on export performance at firm-level. Age does not appear as a key factor on the internationalization of Portuguese wine firms
This paper investigates the presence of spatial spillovers in firms’ productive (in)efficiency. For this purpose, a spatial stochastic frontier model is specified and estimated, accounting for spatial dependence and persistent and transient (in)efficiency. This approach is applied to a panel dataset from 2014 to 2019 of Portuguese wineries. Apart from the traditional input and output quantities used in the estimation of a production function, the novelty of this study is the inclusion of information on the firms’ exact location, which allows incorporating the neighboring dependence in the productive efficiency analysis. Empirical findings show that despite the Portuguese wineries’ technological positive dependence on spatial closeness for both inputs and outputs, the geographic closeness is not strong enough to provide overall productive efficiency gains.
