Development agencies spend approximately US$ 400 million per year on landmine clearance. Yet many cost–benefit evaluations suggest that landmine clearance is socially wasteful because costs appear to far outweigh social benefits. This paper presents new estimates of the benefits of clearing...

This paper presents estimates of the benefits of clearing landmines in two provinces in rural Cambodia using the contingent-valuation (CV) method. The data came from a survey where we asked respondents referendum-type questions that elicit their willingness to pay for landmine clearance. The...

We examine the long-term impacts of international migration by comparing immigrants who had successful ballot entries in a migration lottery program, and first moved almost a decade ago, with people who had unsuccessful entries into those same ballots. The long-term gain in income is found to be...

Many developing countries lack spatially disaggregated price data. Some analysts use "no-price” methods by using a food Engel curve to derive the deflator as that needed for nominally similar households to have equal food shares in all regions and time periods. This method cannot be tested in...

Measuring the gain in income from migration is complicated by non-random selection of migrants from the general population, making it hard to obtain an appropriate comparison group of non-migrants. This paper uses a migrant lottery to overcome this problem, providing an experimental measure of...

Although there has been much discussion in the literature about the impacts of farmland loss (due to urbanization) on household livelihoods, no econometric evidence of these effects has been provided thus far. This paper, hence, is the first to quantify the effects of farmland loss on household...

The results of three surveys of freshman economics students (2008-2010) at the Waikato Management School, New Zealand, suggest that incoming students have significant levels of prior economics knowledge. Given this head start in knowledge, we have expanded our freshman lecture material with more...
