Perceptual Density of Guava Juice: The Effect of Image Location and Surface Texture

Guava is known for its rough (astringent) appearance and texture; feature attached to its nutritional benefits but rejected from consumers’ point of view. This study deals with the rough property of guava juice through packaging expecting to influence its perceived density. Two studies were designed by manipulating (a) the location of the image on the bottle and (b) the surface texture of the bottle, controlling for transparency. Results confirm that it is possible to shift the perception of density in guava juice (a) locating the image of the fruit on the top (not the bottom) of the bottle and (b) using a smooth surface texture (not a rough) on an opaque bottle. Concerning practical implications, agribusinesses should enforce the use of sensory marketing strategies to sell the best of fruits and vegetables.     

The heteroskedasticity-consistent covariance estimator in accounting

The main purpose of this paper is to compare the White (1980) heteroskedasticity-consistent (HC) covariance matrix estimator with alternative estimators. Many regression packages compute the White (1980) heteroskedasticity-consistent (HC) covariance matrix estimator. The common procedure in Accounting and Finance research to deal with the heteroskedasticity problem is based on this estimator, despite its worse finite-samples properties when compared with other consistent estimators. In this paper we compare several HC covariance matrix estimators based on a sample of 3706 European listed companies from Austria, Finland, France, Germany, Greece, Ireland, Italy, Netherlands, Norway, Portugal, Spain, Sweden and the United Kingdom. We conclude that HC standard errors increase when finite-samples more appropriate estimators are considered and in the most part of countries the Ohlson (1995) model coefficients estimates became statistically insignificant. This can be explained by the high leverage points in the design matrix. To the best of our knowledge it is the first time that these alternative estimators are compared with the one of White (1980) in accounting research.     

Dynamic technological specialization,aggregated convergence and growth

This paper focuses on the contribution of dynamic technological specialization to aggregated growth and convergence. Certain theoretical approaches (Structuralism) maintain the view that being specialized in ‘correct’ technologies helps to achieve: i) sustainable rhythms of long-run growth; ii) accelerated catching up and higher rhythms of convergence in delayed countries. Using an endogenous growth model for a 23 countries sample between 1980 and 2010, the work contrasts those hypotheses by using static and dynamic approaches for technological specialization in comparison to other technological variables. Empirical results do not confirm that any ‘good’ specialization matters to growth and convergence at an aggregated level, neither under static nor dynamic approaches. The key elements to aggregated convergence and growth are more linked to spillovers of technological diffusion and to country-specificities (technological capabilities and capacities, domestic technical efforts, national innovation systems, industrial innovation processes, etc.) as it is pointed out by catching-up theories.     

Which manufacturing firms learn by exporting?

Using a longitudinal database (1996–2003) at the plant level, this article analyses the causal nexus between international trade engagement and productivity in Portugal. By applying the propensity score matching and a differences-in-differences estimator, the learning-by-exporting hypothesis is analysed in particular. A higher growth of labour productivity and total factor productivity is found for new exporting firms. To uncover the channels through which the learning effects are driven, the same methodology is applied to some sub-samples. Learning effects are higher for new exporters that are also importers or start importing at the same time. Other factors affecting learning ability are found in firms exporting to more developed markets, in those that achieve a certain threshold of export intensity and mainly for those firms that belong to sectors where Portugal has a comparative disadvantage.     

Customer satisfaction's key factors in Spanish grocery stores: Evidence from hypermarkets and supermarkets

The marketing literature has shown how certain attributes of the store are key for grocery retailers to differentiate themselves in the final markets. From this preliminary consideration the present work proposes a step forward by ascertaining the main factors that underlie the attributes of the store which have already been identified in the literature. All of this is taken into account with the object to examine which of these factors presents a greater influence on customer satisfaction. To test the proposed analysis, a sample of 358 Spanish customers that had carried out their purchase in different types of grocery stores (in particular, hypermarkets and supermarkets) has been analyzed considering a key variable of retail patronage behavior: the store format in which the purchase had been carried out. This study has enabled us to obtain interesting conclusions about the variables that have the most influence on customer satisfaction, providing useful managerial recommendations for decision-making in grocery retailing.     

The demand for alcoholic beverages in Spain

The objective of this study is to analyze the main determinants of alcoholic beverages consumption at home. Data comes from the latest Spanish Household National Survey, which provides information on expenditure and quantities of different food products by household. Because households are interviewed only 1 week, a large number of zeros have been recorded. Among the existing censured demand models (the double hurdle (DH) model; the purchase‐infrequency model; and the Tobit purchase‐infrequency model, among others) and after carrying out model selection tests, the DH model has been finally estimated. All expenditure elasticities are positive, corresponding the highest value to spirits. Own price elasticities are negative and also in this case the spirits exhibit the highest value. Socio‐economic variables also play an important role in explaining consumer purchase and consumption decisions.     

An analysis of health expenditure on a microdata population basis

The objective of this paper is to analyse the hospitalisation and the pharmaceutical expenditures of a population. To do so, we will use cross-sectional information for the year 2004, referring to the whole population of one of the seventeen autonomous communities that make up the Spanish public health system, namely, Aragón. Given the important proportion of null expenditures, a model that takes into account the censored nature of the data must be specified. In our case, the model we choose is Heckman's (1979) selection model. The results are conclusive. i) Age, being a pensioner and being of Spanish nationality positively influence the generation of both types of expenditure; ii) on the contrary, the distance from the health centre to the hospital affects them negatively; iii) sex notably influences the generation of both types of expenditure, women generating higher level of expenditures; iv), in both cases, significant differences appear associated with the zone to which the user belongs; and v) we have also found that pharmaceutical expenditure depends significantly on the doctor who is prescribing.     

Trust and community building in the Doñana (Spain) toxic spill disaster

Appeals to public participation and, more generally, to a wider involvement of civic networks in the management of environmental conflicts are becoming more common after the difficulties that both the Market and the State appear to have in regulating these conflicts. The concern of this paper is with how central elements in civic society, such as interpersonal trust and community-building mechanisms, are influenced by environmental catastrophes. The case of the toxic spill disaster in Doñana, Spain, is presented in order to examine whether this accident had any effect on interpersonal trust and the mobilization of civic networks in the area. From the analysis, it can be concluded that involvement of civic networks in the management of these situations depends on the magnitude (real or perceived) of the disaster but also on the performance of public institutions regarding the event.
