The willingness to pay for a coyote conservation program is estimated using a novel payment-vehicle, based on how many coyotes respondents would be willing to sponsor. This hypothetical scenario mimics an increasingly popular type of actual market. Data from a phone survey conducted in Prince...

A potential concern in “multiple bounded discrete choice” contingent valuation surveys – where the respondent is asked to express voting certainty, rather than a simple yes or no, on a large number of payment amounts (bids) – is whether responses are influenced by the particular position...

This paper estimates the relative technical efficiency of Brazilian municipalities in the public education using the DEA model along with tobit regressions with the aid of re sampling methods. The jackstrap method enabled the estimation of robust efficiency scores, while the bootstrap allowed...

This paper proposes a nonparametric method for evaluating treatment effects in the presence of both treatment endogeneity and attrition/non-response bias, using two instrumental variables. Making use of a discrete instrument for the treatment and a continuous instrument for...

This paper develops a nonparametric methodology for treatment evaluation with multiple outcome periods under treatment endogeneity and missing outcomes. We use instrumental variables, pre-treatment characteristics, and short-term (or intermediate) outcomes to identify the average treatment...

The ability to allow for flexible forms of unobserved heterogeneity is an essential ingredient in modern microeconometrics. In this paper we extend the application of instrumental variable (IV) methods to a wide class of problems in which multiple values of unobservable variables can be...

This paper develops characterizations of identified sets of structures and structural features for complete and incomplete models involving continuous or discrete variables. Multiple values of unobserved variables can be associated with particular combinations of observed variables. This can...

Die Lissabon-Agenda sieht eine Steigerung der Ausgaben für Forschung und Entwicklung bis zum Jahr 2010 auf drei Prozent des Bruttoinlandsprodukts vor. Europa will damit zu einem der wettbewerbsfähigsten und dynamischsten Wirtschaftsräume werden. Wesentlich für die Zukunftsfähigkeit eines...
