Low-quality infrastructure services are persistent in developing countries, a situation mainly affecting the poorest households in contexts of high rates of informal access and heavily subsidized services. This paper exploits choice experiments, specifically designed for formal and informal...

Poorly maintained public infrastructure is common in low- and middle-income countries, with consequences for service delivery and public health. By experimentally identifying the impact of incentives for local maintenance for both providers and potential users, this paper provides one of the...

The security of natural gas supply is an important issue for all EU countries due to the region's heavy dependence on imported supply sources and in light of energy demand for gas that is continuously increasing. Discussions have emphasised strategies for securing the supply at the macro level,...

We estimate willingness to pay (WTP) for better quality of tap water on a unique cross-section sample from 10 OECD countries. On the pooled sample, households are willing to pay 7.5% of the median annual water bill to improve the tap water quality. The highest relative WTP for better tap water...

The paper focuses on the ongoing debate on non-market valuation, including the valuation environmental goods, and the opportunity to use contingent valuation for policy guidance. In fact, contingent valuation critics argue that reported willingness to pay answers do not reflect real economic...

As previously argued, the correlation between included and omitted regressors generally causes inconsistency of standard estimators for count data models. Using a specific residual function and suitable instruments, a consistent generalized method of moments estimator can be obtained under...

There is growing interest in discrete-choice experiment (DCE) as a method to elicit consumers' preferences in the health care sector. Increasingly this method is used to determine willingness to pay (WTP) for health-related goods. However, its external validity in the health care domain has not...

We focus on two utility programs intended to reduce energy usage and the associated CO2 emissions-a home energy audit and rebates on the purchase of high-efficiency air-source heat pumps. We use a unique panel dataset from participating and non-participating households to estimate the average...
