The Muted Vibrancy of Roman Catholicism in Contemporary Portugal: Corporal Works of Mercy in a Time of Austerity. CES Open Forum Series #25 2018-2019

This paper concerns the role and function of religious-based organizations in strengthening associational life. Taking Portugal as a case study, it asks whether the concept of muted vibrancy provides theoretical understanding to the role of Catholicism in contemporary Portuguese society. That is, how might a church in a newly consolidated democratic regime, in a time of economic crisis, with a past relationship to a fascist regime, and with declining numbers of adherents, contribute to the deepening of democracy

Reconsidering Economic Relations and Political Citizenship in the New Iberia of the New Europe: Some Lessons from the Fifteenth Anniversary of the Accession of Portugal and Spain to the European Union. CES Working Paper, no. 94, 2003

The purpose of this paper is to use the fifteenth anniversary of the accession of Portugal and Spain to the European Union as an opportunity to reflect on what has happened to both countries since 1986. It examines the integration process and how it has affected political, economic and social developments in Portugal and in Spain over the last fifteen years. In our view, and on balance, Spain and Portugal have benefited from accession. Since the last century, the obsession of Spanish and Portuguese reformists has been to make up the lost ground with modernized Europe. EU membership has been a critical step in this direction. The record of the past fifteen years is that this dream is becoming an economic reality. Despite impressive achievements, however, namely, since 1986, Portugal’s average per capita income has grown from 56 percent of the EU average to about 74 percent, whereas Spain’s has grown to 83 percent—both Iberian countries still have a long way to go to reach the EU average wealth. In addition, the question of Iberian and/or European citizenship, and its impact on the Portuguese and Spanish, remains open

Patient Welfare and Patient Compliance: An Empirical Framework for Measuring the Benefits from Pharmaceutical Innovation

The main goal of this paper is to develop an empirical framework for evaluating the patient welfare benefits arising from pharmaceutical innovation. Extending previous studies of the welfare benefits from innovation (Trajtenberg, 1990; Hausman, 1996), this paper unpacks the separate choices made by physicians and patients in pharmaceutical decisionmaking and develops an estimable econometric model which reflects these choices. Our proposed estimator for patient welfare depends on (a) whether patients comply with the prescriptions they receive from physicians and (b) the motives of physicians in their prescription behavior. By focusing on compliance behavior, the proposed welfare measure reflects a specific economic choice made by patients. We review evidence that the rate of noncompliance ranges up to 70%, suggesting an important gulf between physician prescription behavior and realized patient welfare. Since physicians act as imperfect but interested agents for their patients, the welfare analysis based on compliance must account for the nonrandom selection of patients into drugs by their physicians. The key contribution of this paper resides in integrating the choices made by both physicians and patients into a unified theoretical framework and suggesting how the parameters of such a model can be estimated from data.

STAND: A Spatio-Temporal Algorithm for Network Diffusion Simulation

Information, ideas, and diseases, or more generally, contagions, spread over space and time through individual transmissions via social networks, as well as through external sources. A detailed picture of any diffusion process can be achieved only when both a good network structure and individual diffusion pathways are obtained. The advent of rich social, media and locational data allows us to study and model this diffusion process in more detail than previously possible. Nevertheless, how information, ideas or diseases are propagated through the network as an overall process is difficult to trace. This propagation is continuous over space and time, where individual transmissions occur at different rates via complex, latent connections. To tackle this challenge, a probabilistic spatiotemporal algorithm for network diffusion (STAND) is developed based on the survival model in this research. Both time and spatial distance are used as explanatory variables to simulate the diffusion process over two different network structures. The aim is to provide a more detailed measure of how different contagions are transmitted through various networks where nodes are geographic places at a large scale

Why don't lenders renegotiate more home mortgages? redefaults, self-cures, and securitization

We document the fact that servicers have been reluctant to renegotiate mortgages since the foreclosure crisis started in 2007, having performed payment-reducing modifications on only about 3 percent of seriously delinquent loans. We show that this reluctance does not result from securitization: Servicers renegotiate similarly small fractions of loans that they hold in their portfolios. Our results are robust to different definitions of renegotiation, including the one most likely to be affected by securitization, and to different definitions of delinquency. Our results are strongest in subsamples in which unobserved heterogeneity between portfolio and securitized loans is likely to be small and in subprime loans. We use a theoretical model to show that redefault risk, the possibility that a borrower will still default despite costly renegotiation, and self-cure risk, the possibility that a seriously delinquent borrower will become current without renegotiation, make renegotiation unattractive to investors.

Revisiting path-type covering and partitioning problems

This is a survey article which is at the initial stage. The author will appreciate to receive your comments and contributions to improve the quality of the article. The author's contact address is [email protected] problems belong to the foundation of graph theory. There are several types of covering problems in graph theory such as covering the vertex set by stars (domination problem), covering the vertex set by cliques (clique covering problem), covering the vertex set by independent sets (coloring problem), and covering the vertex set by paths or cycles. A similar concept which is partitioning problem is also equally important. Lately research in graph theory has produced unprecedented growth because of its various application in engineering and science. The covering and partitioning problem by paths itself have produced a sizable volume of literatures. The research on these problems is expanding in multiple directions and the volume of research papers is exploding. It is the time to simplify and unify the literature on different types of the covering and partitioning problems. The problems considered in this article are path cover problem, induced path cover problem, isometric path cover problem, path partition problem, induced path partition problem and isometric path partition problem. The objective of this article is to summarize the recent developments on these problems, classify their literatures and correlate the inter-relationship among the related concepts
