This study investigates how consumers value carbon dioxide (CO2) emissions of food by conducting a choice experiment before an ecolabel is attached on some foods in Japan. Participants are asked to buy some Satsuma mandarin oranges based on price and CO2 emissions and take them home. The following results are obtained: (i) the willingness-to-pay (WTP) estimate for the reduction of 1 g CO2 emiss...

To assess the impact of taxation on the consumption of sugar-sweetened beverages (SSB), most studies consider the average consumer. Individual consumption is, however, very heterogeneous. In this paper, we propose a three-step methodology to assess the impact of SSB taxation on individual consumption. First, we use a disaggregation method to recover individual consumption from observed househol...

Sustainable agricultural practices (SAPs) that lead to an increase in productivity are central to the acceleration of economic growth; this will alleviate poverty and help to overcome the recurrent food shortages that affect millions of households in Africa. However, the adoption rates of SAPs remain below expected levels. This paper analyzes the factors that facilitate or impede the probabilit...

The EU advocates a household waste recycling rate of more than 70%. Although the Netherlands already years ago invested in recycling policies heavily, this is still a large challenge as nowadays on average this rate is approximately 50% and nearly no municipalities have a rate above 70%. Given the experience, it is possible to learn from the Dutch experience which policies are effective in incr...

By 2022, the European Commission seeks to introduce harmonized, mandatory front-of-pack (FOP) nutrition labeling. The color-graded Nutri-Score is at heart of debate. Yet, little known about how information provided in back-of-pack (BOP) tables interacts with evaluative FOP labels, such as Nutri-Score, and if different consumer groups use both cues differently when making food choices. Our objec...

Endogeneity of ...

The TATA-binding protein (TBP) plays a crucial role in cellular transcription catalyzed by all three DNA-dependent RNA polymerases. Previous studies have shown that TBP is targeted by the poliovirus (PV)-encoded protease 3C(pro) to bring about shutoff of cellular RNA polymerase II-mediated transcription in PV-infected cells. The processing of the majority of viral precursor proteins by 3C(pro) ...
