Where Does the Fairtrade Money Go? How Much Consumers Pay Extra for Fairtrade Coffee and How This Value Is Split along the Value Chain

Fairtrade certification aims at transferring wealth from the consumer to the farmer; however, coffee passes through many hands before reaching final consumers. Bringing together retail, wholesale, and stock market data, this study estimates how much more consumers are paying for Fairtrade-certified coffee in US supermarkets and finds estimates around $1 per lb. I then assess how this price premium ...

Social Image Concerns and Welfare Take-Up

Using a laboratory experiment, we present first evidence that social image concerns causally reduce the take-up of an individually beneficial transfer. Our design manipulates the informativeness of the take-up decision by varying whether transfer eligibility is based on ability or luck, and how the transfer is financed. We find that subjects avoid the inference both of being low-skilled (ability stigma) ...

Is Socially Responsible Production a Normal Good?

This paper uses a controlled laboratory experiment to investigate the effect of wealth on individual social responsibility (ISR), defined as choosing a more socially responsible product if a cheaper alternative is available. We find that rich consumers are significantly less likely to engage in ISR than poor consumers. This suggests that socially responsible production conditions may not be normal ...

Who Cares about Social Image?

This paper experimentally investigates how concerns for social approval relate to intrinsic motivations to purchase ethically. Participants state their willingness-to-pay for both a fair trade and a conventional chocolate bar in private or publicly. A standard model of social image predicts that all increase their fair trade premium when facing an audience. We find that the premium is higher in public ...

Global Food Security

According to the current report on the Millennium Development Goals, the share of undernourished people living in the developing world has fallen from 23.3% in 1990-1992 to 12.9% in 2014-2016 (projection). Despite this progress towards global food security, about 795 million people worldwide (or 780 million people in developing regions) will remain undernourished in 2014-2016. Put differently, more ...

Do Prices and Purchases Respond Similarly to Soft Drink Tax Increases and Cuts?

While in January 2012, Denmark increased the long-standing tax on sugary soft drinks, the tax was cut byhalf in July 2013 and then completely repealed in January 2014. In this study, we examine whetherincreases and cuts of the soft drink tax lead to similar over- or under-shifting to prices and to similardemand responses. We use longitudinal scanner data of 1,282 Danish households to estimate within-product ...

Fairness in Markets and Market Experiments

Whether pro-social preferences identified in economic laboratories survive in natural market contexts is an important and contested issue. We investigate how fairness in a laboratory experiment framed explicitly as a market exchange relates to preferences for fair trade products before and after the market experiment. We find that the willingness to buy at a higher price when higher wages are paid ...
