- Efeito das Ações de Marketing na Escola sobre o Comportamento de ConsumoPublication . Afonso, Ana; Afonso, Oscar; Bandeira, Ana M.Our study aims to analyze the effect of marketing actions in schools, driven by health-food companies, on the consumption behavior of students to understand whether they (a) show higher preference for healthy food and drinks; (b) choose to take such goods home; are aware that consuming these goods is a healthy habit; and (c) realize that sales of the companies that produce such health foods and drinks improve. We wish to contribute to the literature by using an experimental exercise in three schools in Porto district, Portugal. Our sample included 307 students aged from 6 to 16 years old, with 153(154) students belonging to the experimental (control) group. The regression results confirm our hypotheses. In particular, we found that the level of education of parents did not seem to have an impact, the results across male and female students are very close and that students’ age did not affect the results between groups, but did affect score values.
- Effect of the Tax System ON R&D Intensity, Growth, Wages and Consumption SharePublication . Afonso, Oscar; Bandeira, Ana M.; Magalhães, ManuelaWe propose a general equilibrium knowledge-driven (semi-)endogenous-growth model with horizontal R&D, which is extended to consider two types of labour, skilled and unskilled, and exogenous government expenditure, financed through taxes on financial assets and on labour income, to analyse the implications of the tax system on R&D intensity, economic growth, wage inequality and consumption share in the output. In particular, we show that: (i) taxes have negative influence in the consumption share, being higher the marginal effect of the labour-income tax; (ii) for any given government expenditure share, an increase (a decrease) in financial-assets tax decreases (increases) the labour-income tax; (iii) only the financial-assets tax affects negatively the R&D intensity and the skill-premium; thus, to reduce the skill-premium the financial-assets tax must increase; (iv) ignoring the effect on wage inequality and on R&D intensity, taxes are substitutes.
- Growth and welfare effects of corruption penaltiesPublication . Afonso, Oscar; Bandeira, Ana M.; Lima, Pedro G.This paper analyses the steady-state effect of business corruption penalties on economic growth, corruption and welfare. To that end, the baseline horizontal R&D growth model is extended to include corruption, which is generated in intermediate goods production. Taxation on corruption depresses profits in production but also wages, leading to labor being reallocated from production to R&D, and, therefore, to a higher economic growth rate. Moreover, it also reduces corruption and increases welfare if preferences towards a corruption-free environment are strong enough. The results are in line with the data observed for 15 EU countries.
- Labour-market institutions, (un)employment, wages, and growth: theory and dataPublication . Afonso, Oscar; Bandeira, Ana M.; Magalhães, ManuelaWe analyse the implications of labour-market institutions on wage inequality in favour of skilled labour, on relative unemployment of unskilled labour, and on the economic growth rate in two clusters resulting from 27 OECD countries: Cluster 1, closely related with the Anglo-Saxon model, and Cluster 2, dominated by the Continental-European model. By linking the unskilled wage to the skilled one in Cluster 2, due to the indexation of social benefits to per-capita income, we accommodate the observed paths of the three variables in both clusters between 1991 and 2008: Cluster 1 presents a higher wage inequality in favour of skilled labour, a lower unemployment of the unskilled labour, and a better economic growth rate
