On Cluster Robust Models, José Bayoán Santiago Calderón
CGU Theses & Dissertations
Cluster robust models are a kind of statistical models that attempt to estimate parameters considering potential heterogeneity in treatment effects. Absent heterogeneity in treatment effects, the partial and average treatment effect are the same. When heterogeneity in treatment effects occurs, the average treatment effect is a function of the various partial treatment effects and the composition of the population of interest. The first chapter explores the performance of common estimators as a function of the presence of heterogeneity in treatment effects and other characteristics that may influence their performance for estimating average treatment effects. The second chapter examines various approaches …

Incentivizing Biodiversity Conservation: The Ecological Icms In Brazil, Erin Franks
CMC Senior Theses
This study evaluates the effectiveness of the ecological ICMS (ICMS-e) in the Brazilian Amazon, an intragovernmental transfer for incentivizing biodiversity conservation. Tax funds are passed from state governments to municipalities in proportion to the amount of protected area within their borders; biological reserves, sustainable use areas, and indigenous lands are all considered. Econometric analysis using a fixed effects model found that the policy had little positive effect on increasing protected areas compared to the significant negative influence of poor land tenure, agricultural influences, and lack of monitoring for illegal deforestation. However, the policy may increase municipal governments' acceptance of and …
