The route of SARS-CoV-2 from faeces to wastewater treatment plants is analysed.• Viral load in the faeces of positive people for SARS-CoV-2 is 5•10 3 -10 7.6 copies/mL. • Viral load decreases from 2 copies/ 100 mL to 3•10 3 copies/mL when entering a WWTP. • For WBE high uncertainty of viral loads remains, and further research is needed. • CoVs inactivation in WWTPs is enhanced by tertiary treatments and disinfection.

This paper discusses the role of relational goods and television viewing for individual happiness. Using individual data from the World Values Survey, we find evidence of a positive effect of relationality on life satisfaction, and a negative effect of television viewing on relational activities. Both relationships are strongly significant and robust to the use of alternative indicators of relationality. The results are also robust to estimation by instrumental variables to deal with possible simultaneity. We interpret these findings as an indication that the pervasive and increasing role of television viewing in contemporary society, through its crowding out effect on relational activities, contributes to the explanation of the income-happiness paradox.JEL Classification: A12, D12, I31

This article explores parallels between the debate prompted by Pareto's reformulation of choice theory at the beginning of the twentieth century and current controversies about the status of behavioural economics. Before Pareto's reformulation, neoclassical economics was based on theoretical and experimental psychology, as behavioural economics now is. Current 'discovered preference' defences of rational-choice theory echo arguments made by Pareto. Both treat economics as a separate science of rational choice, independent of psychology. Both confront two fundamental problems: to find a defensible definition of the domain of economics, and to justify the assumption that preferences are consistent and stable.
