This paper combines two strands of the experimental sunspot literature. It extends the rare literature that focuses experimentally on the coordination problems caused by sunspot variables. It also extends the literature that focuses on coordination games that have a payoff-dominant and a...

In 2015, Costa Rica was the first country in Latin America to approve a National Policy for Sustainable Public Procurement (SPP). In 2018, a research team from DIE studied the efforts to make SPP a reality in Costa Rica and developed policy conclusions, partly drawing on international...

Preferences over wealth can explain why households do not spend more when real interest rates fall, because they save more than optimal under a standard model. However, little is known about preferences over wealth empirically. We run an intentionally simple lab experiment on intertemporal...

A sunspot variable is any random variable that is not related to fundamental factors of the economy but a potential coordination device. The coordination power of sunspots has been analysed in theory and in experiments. However, some have discussed whether sunspots, e.g., public announcements...
