Bayesian analysis of FIAPARCH model: an application to São Paulo stock market

In this paper, we develop a Bayesian analysis of a FIAPARCH(p,d,q) model for parameter estimation and conditional variance prediction. In order to study the inference problem we use the Metropolis-Hastings algorithm.This methodology is illustrated in a simulation study and it is applied to a set of observations concerning the returns of IBOVESPA value

Business-Science Research Collaboration under Moral Hazard

I analyze, in the context of business and science research collaboration, how the characteristics of partnership agreements are the result of an optimal contract between partners. The final outcome depends on the structure governing the partnership, and on the informational problems towards the efforts involved. The positive effect that the effort of each party has on the success of the other party, makes collaboration a preferred solution. Divergence in research goals may, however, create conflicts between partners. This paper shows how two different structures of partnership governance (a centralized, and a decentralized ones) may optimally use the type of project to motivate the supply of non-contractible efforts. Decentralized structure, however, always choose a project closer to its own preferences. Incentives may also come from monetary transfers, either from partners sharing each other benefits, or from public funds. I derive conditions under which public interventiocollaboration, basic research, applied research, project, firms, universities, partnership governance

Assessment of National Migration Policies: An emerging picture on admissions, treatment and enforcement in developing and developed countries

This paper presents an internationally comparable assessment of several dimensions of migration policies as of early 2009. For a selected set of 28 countries, both developed and developing, we analyse the admission criteria, policies on integration and treatment of migrants, and efforts to enforce those policies. Irregular migration is a particular area of focus. The analysis distinguishes between different entry regimes, namely: labour migrants (high or low skilled, with a permanent or a temporary permit), those who move with a family-related visa, humanitarian migrants (asylum seekers and refugees), international visitors and international students. The data is drawn from an assessment by country experts as well as by desk-research of HDRO staff.Migration policies, admission, treatment, enforcement

The disconnect between indicators of sustainability and human development

This paper presents an initial review of the theoretical and measurement discussions of sustainability and its relation to human development. As we show in this paper, there is an overall consensus about the importance of sustaining development and well-being over time, but in reality different development paradigms lead to different definitions and measures of sustainability. We review some of those measures, among which the Adjusted Net Savings (a green national accounting measure calculated by the World Bank and rooted in a weak concept of sustainability), the Ecological Footprint (calculated by the Global Footprint Network and rooted in a strong concept of sustainability, where environment is considered a critical resource), and the carbon dioxide emissions (a simple environmental indicator, used in international debate of climate change). Our analysis shows conflicting conclusions when studying the correlations between these indicators of sustainability and existing human development indicators, namely HDI, which emphasizes the need for further analysis to understand what “sustainable human development” means. Nevertheless, as we show here, over time there has been a close link between higher economic performance and energy consumption, which has been mostly based in the use of fossil fuels.sustainability, human development, measurement, energy.

Health Care and Health Outcomes of Migrants: Evidence from Portugal

This paper studies the performance of immigrants relative to natives, in terms of their health status, use of health care services, lifestyles, and coverage of health expenditures. We base the analysis on international evidence that identified a healthy immigrant effect, complemented by empirical research on the Portuguese National Health Survey. Furthermore, we assess whether differences in health performance depend on the personal characteristics of the individuals or can be directly associated with their migration experience.Migration, health status, health care, healthy immigrant effect, Portugal
