Job Satisfaction Determinants of Tertiary Graduates in Europe
2015
Abstract Factors affecting the job satisfaction of tertiary graduates are studied using recent data on 13 European countries from 2010–11. Special attention is given to differences between bachelors and masters. It is found that in many countries, master's degree decreases job satisfaction. Moreover, it never increases the job satisfaction of female employees. Masters are more sensitive than bachelors to career opportunities, variety in work and whether learning is required in the job; while bachelors are more sensitive to the risk of moving to a less interesting job and monetary compensation. Overeducation generally does not affect the job satisfaction of bachelors, but strongly decreases …
Modelling a proportion response variable using generalised additive models for location scale and shape
2015
In this paper two alternative approaches are proposed to model a response variable Y measured on the interval from zero to one, including both zero and one. The first proposed model employs a flexible four parameter distribution for 0 < Y < 1, for example a logit skew exponential power distribution, inflated by including point probabilities at 0 and 1. The second proposed model is a generalised Tobit model, obtained from a flexible four parameter distribution on (-infinity;+infinity), for example the skew exponential power distribution, by censoring below 0 and above 1. The proposed models are applied to a real data set and compared with current popular models.
Income inequality, fiscal stimuli and political (in)stability
2016
Using data for a large panel of countries, this paper investigates the role played by income inequality and fiscal stimuli episodes in shaping the likelihood of political stability. By means of Tobit estimations, we show that a rise in inequality increases the probability of government crises. However, such adverse distributional effect is reduced when expansionary or increasingly expansionary fiscal stimuli episodes or successful fiscal stimuli programs are put in place.
Social Embeddedness in Farmers Decision Making
2014
Reciprocal interactions among farmers and consumers can be seen as the central point of market exchanges in Civic Agriculture (CAs). This work exploits the concept of social embeddedness as a conceptual tool for describing some phenomena related to CA. Social embeddedness concept might help to understand how consumers and producers behave in the market beyond the paradigm of neoclassical economics theory. The objective of this study is to empirically evaluate which attitudes may influence farmers decision to participate to several types of CAs. Our results confirm the strong role of social embeddedness phenomenon in those forms of CAs characterized by personal relations between farmers and …
Centile estimation for a proportion response variable
2015
This paper introduces two general models for computing centiles when the response variable Y can take values between 0 and 1, inclusive of 0 or 1. The models developed are more flexible alternatives to the beta inflated distribution. The first proposed model employs a flexible four parameter logit skew Student t (logitSST) distribution to model the response variable Y on the unit interval (0, 1), excluding 0 and 1. This model is then extended to the inflated logitSST distribution for Y on the unit interval, including 1. The second model developed in this paper is a generalised Tobit model for Y on the unit interval, including 1. Applying these two models to (1-Y) rather than Y enables model…

Can Dried Fruits Replace Unhealthy Snacking among Millennials? An Empirical Study on Dried Fruit Consumption in Italy
2023
The consumption of dried fruits in place of unhealthy snacks, which are rich in sugars, salt, and fats, could represent a valid option for reaching the daily intake recommended by the WHO for fruits and for encouraging the adoption of a sustainable diet. However, the consumption of dried fruits is lower than that of unhealthy snacks, especially among young people. Therefore, to foster young people’s intentions to consume dried fruits instead of unhealthy snacks, it is important to identify the factors underlying millennials’ consumption intentions. Using a convenience sample of 174 Italian millennials, this paper aimed to understand the factors influencing young people’s i…
