Better Regulation in Latin American Countries: A tool for accountability?

In the last few years, a steadily increasing number of Latin American countries have been adopting policy assessment instruments and new governance structures for them, as part of their policymaking process. Even though the literature argues that these instruments serve, among other things, as tools for accountability, for this to be so, it is necessary to take into account the legal system, decision-making process, and regulatory relationships that exist in the adopting countries. This Thesis researches the policy assessment arrangements adopted and implemented in the Latin American region to understand why are these countries adopting and implementing tools for policy evaluation? Can this contribute towards regulatory accountability, and if so, in which conditions? The Thesis first analyzes the rationales that these countries might have to adopt these regulatory policy arrangements. It then studies the various tools used for policy assessment, paying attention to the scope of the assessments, the times and the stages on which regulations are assessed, referred to as the Policy Evaluation Cycle (PEC), as well as to the governance of these processes. The Thesis develops a framework where each of these components are organized and classified based on which goals or rationales they serve. This can assist countries on deciding how to implement their policy evaluation arrangements, to serve their own goals. Since all of the studied countries have presidential systems, this Thesis studies how regulations are made in this system, and the multiple needed delegations for policymaking, which results in various regulatory relationships. Thus, the desired accountability of policymakers towards their different forums makes relevant the adoption this agenda for regulatory accountability reasons. Bringing to together the literatures on public law, accountability and policy evaluation, this Thesis builds a framework for assessing the contribution towards accountability that each stage of the PEC might have in a specific regulatory relationship. The framework shows to which degree the stages, and the cycle as a whole, contribute towards accountability in specific relationships of a presidential constitutional system. The results evidence that even when a policy assessment structure might contribute towards accountability, this contribution is not absolute as it only operates in specific regulatory relationships, and even more, only in some stages of the PEC contributing at different degrees. This framework can be used by governments or regulatory agencies as an instrument to assess the contribution to accountability of their existing or potential regulatory policy structures in order to improve it.

An interdisciplinary analysis of obesity: theory and empirical evidence

The dissertation is structured in three parts. The first part compares US and EU agricultural policies since the end of WWII. There is not enough evidence for claiming that agricultural support has a negative impact on obesity trends. I discuss the possibility of an exchange in best practices to fight obesity. There are relevant economic, societal and legal differences between the US and the EU. However, partnerships against obesity are welcomed. The second part presents a socio-ecological model of the determinants of obesity. I employ an interdisciplinary model because it captures the simultaneous influence of several variables. Obesity is an interaction of pre-birth, primary and secondary socialization factors. To test the significance of each factor, I use data from the National Longitudinal Survey of Adolescent Health. I compare the average body mass index across different populations. Differences in means are statistically significant. In the last part I use the National Survey of Children Health. I analyze the effect that family characteristics, built environment, cultural norms and individual factors have on the body mass index (BMI). I use Ordered Probit models and I calculate the marginal effects. I use State and ethnicity fixed effects to control for unobserved heterogeneity. I find that southern US States tend have on average a higher probability of being obese. On the ethnicity side, White Americans have a lower BMI respect to Black Americans, Hispanics and American Indians Native Islanders; being Asian is associated with a lower probability of being obese. In neighborhoods where trust level and safety perception are higher, children are less overweight and obese. Similar results are shown for higher level of parental income and education. Breastfeeding has a negative impact. Higher values of measures of behavioral disorders have a positive and significant impact on obesity, as predicted by the theory.
