A Bayesian method of distinguishing unit root from stationary processes based on panel data models with cross-sectional dependence

In this paper we develop a Bayesian approach to detecting unit roots in autoregressive panel data models. Our method is based on the comparison of stationary autoregressive models with and without individual deterministic trends, to their counterpart models with a unit autoregressive root. This is done under cross-sectional dependence among the error terms of the panel units. Simulation experiments are conducted with the aim to assess the performance of the suggested inferential procedure, as well as to investigate if the Bayesian model comparison approach can distinguish unit root models from stationary autoregressive models under cross-sectional dependence. The approach is applied to real exchange rate series for a panel of the G7 countries and to a panel of US nominal interest rates data.     

On regression-based tests for persistence in logarithmic volatility models

Building on the work of Pantula (1986), this paper discusses how the hypothesis of conditional variance nonstationarity in the logarithmic family of generalized autoregressive conditional heteroskedasticity (GARCH) and stochastic volatility processes may be tested using regression-based tests. The latter are easy to implement, have well-defined large-sample distributions, and are less sensitive to structural changes than tests based on the quasimaximum likelihood estimator.     

A theory of instrumental and existential rational decisions: Smith,Weber, Mauss,Tönnies after Martin Buber

This paper proffers a dialogical theory of decision-making: decision-makers (DMs) are engaged in two modes of rational decisions, instrumental and existential. Instrumental rational decisions take place when the DM views the self externally to the objects, whether goods or animate beings. Existential rational decisions take place when the DM views the self in union with such objects. While the dialogical theory differs from Max Weber’s distinction between two kinds of rationality, it follows Martin Buber’s philosophical anthropology. The paper expounds the ramifications of the dialogical theory in understanding structures of exchange considering assessments of diverse thinkers.

     

The socioculturalist agenda in economics: Critical remarks of Thorstein Veblen's legacy

The article identifies a cluster of heterodox economists, especially followers of Thorstein Veblen, who are critical of the neoclassical axiom of well-defined preferences. They generally have a problem with the reductionist reasoning that preferences of agents are constituted prior to social interaction. Some of them are proposing somewhat well-defined preferences deduced instead from the tastes of the reference groups with whom the agent identifies. The article does not question the relevance, with respect to economics, of the preferences of groups. Rather, it challenges a muscular view of such preferences which is being uncritically borrowed, inter alia, from functionalist sociology and substantivist economic anthropology. Sociologists and anthropologists in general have recently become, from diverse perspectives, critical of the conception of sociocultural tastes as hegemonic. The basic thrust of the article is that the socioculturalist agenda broadly subscribes to a biological/social dichotomy which neglects that tastes also arise from psychobiological developmental processes.     

New Public Management,Service Provision and Non-Governmental Organizations in Bangladesh

New public management (NPM) is now a universal phenomenon dominating the reform agenda of all countries. Bangladesh is no exception. Following the dismal performance of the state-led development the old paradigm of public sector has come under scrutiny. There is now a call for a minimal government. The scale of operations and the role of the government have to be drastically reduced to focus on core functions. In doing so, this will pave the way for the private sector and the civil society organizations to undertake developmental responsibilities in their areas of expertise. This article is an attempt to analyze the significant role played by Non-Government Organizations (NGOs) in rural development service provisions. It argues that the government has to share the developmental responsibilities with NGOs, which have proved their potential in reaching the target population and that an effective partnership is a sine qua non for the meaningful rural development in Bangladesh.     

Sleep Quality and Body Mass Index in College Students: The Role of Sleep Disturbances

Abstract

Objective: Obesity and its comorbidities have emerged as a leading public health concern. The aim of this study was to explore the relationship between body mass index (BMI) and sleep patterns, including duration and disturbances. Methods: A convenience sample of 515 college students completed an online survey consisting of the Pittsburgh Sleep Quality Index (PSQI), and self-reported height and weight to calculate BMI. Univariate and multivariate logistic regression analyses were performed using components of the PSQI as predictors of overweight (BMI ≥ 25). Results: One-third of the participants had BMI ≥ 25, and 51% were poor-quality sleepers (PSQI > 5). Controlling for age and sex, only sleep disturbances were associated with overweight (odds ratio = 1.66, 95% confidence interval [1.08, 2.57]). Conclusions: Sleep disturbances, rather than sleep duration, predicted overweight among young adults; this is consistent with the most recent evidence in the literature. These findings support expanding the scope of wellness programs to promote healthy sleep among students.     

A Pilot Study to Evaluate Ethnic/Racial Differences in Depressive Symptoms,Self-Esteem,and Sexual Behaviors Among Men Who Have Sex with Men

Men who have sex with men (MSM) are at risk for certain physical and psychological health conditions. Ethnic minority MSM are at an increased risk related to the combination of sexual minority and ethnic minority status. The purpose of this pilot study was to compare the levels of depressive symptoms, self-esteem, and sexual behaviors by ethnicity in a sample of MSM (N = 70) residing in South Florida. More than one-third of the sample (N = 26; 37%) had high levels of depressive symptoms. Using non-parametric statistics, statistically significant differences were noted in the levels of depressive symptoms as African-American MSM had higher levels of depressive symptoms when compared to the other ethnic groups. Statistically significant differences were not found when self-esteem and sexual behaviors were compared by ethnicity. Regardless of ethnicity, MSM in this study were at risk for the sequela of depressive symptoms and infections with HIV and/or sexually transmitted infections because of the high levels of unsafe sexual behaviors. More research is needed to explore the relationship of mental health and sexual behaviors among the various ethnic groups of MSM.

REFORM SUPPORT IN TIMES OF CRISIS: THE ROLE OF FAMILY TIES

We argue that an important determinant of voters' support for economic reform is the strength of family ties. While the “crisis hypothesis” predicts that crises facilitate reform, we show in a political economy model that this relation can break down, and even reverse, when agents take into account the effect of reform on their family members. Applied to southern European countries with strong family ties, the model rationalizes why the extremely high (youth) unemployment following the Great Recession has not led to more substantial labor market reforms. In such countries austerity might block rather than foster additional structural reforms. (JEL D64, D72, J48)     

Constructing the digital patient: Patient organizations and the development of health websites

In order to understand the constraints and challenges of realizing the democratic potentials of the Internet, this paper focuses on the attempts of three Dutch patient organizations to develop health websites. The authors describe how these patient organizations had to overcome specific barriers to develop their digital services. All three organizations faced certain constraints that had negative consequences for the plans they wanted to realize. Lack of financial resources and manpower were the main reasons why these patient organizations could not develop interactive parts of their website or provide personal advice services. Other barriers the patient organizations had to overcome were getting access to digital expertise to build the websites. The paper shows that the development of a website is a very demanding task, even for patient organizations that have in-house expertise with computers and Internet. Moreover, the paper shows that patient organizations do not consider the involvement of patients as crucial for the design of health websites. This research thus confirms previous research findings that users, in this case patients, are largely absent from the design process of information and communication technologies Finally, the paper shows how patient organizations' websites contribute to a redefinition of the patient from being a passive actor towards one who is an active participant in his or her care.
