A simple estimation method and finite-sample inference for a stochastic volatility model

The aim of the paper is to fulfill the gap for testing hypotheses on parameters of the log-normal stochastic volatility model, more precisely, to propose finite sample exact tests in the sense that the tests have correct levels in small samples. To do this, we examine method-of-moments-based tests and we provide explicit expressions for all the moments and the estimators which simplifies highly the test procedures. We then state the asymptotic distribution of the estimator as well as that of the proposed test statistics for testing the null hypothesis of no persistence in the volatility. We then compare the finite sample properties of the standard asymptotic techniques to that of Monte Carlo tests which are valid in finite samples and allow for test statistics whose null distribution may depend on nuisance parameters. In particular Maximized Monte Carlo tests introduced by Dufour (1995) have the exact level in finite samples when the p-value function is maximized over the entire set of nuisance parametersexact tests, Monte Carlo tests, C-alpha tests, stochastic volatility model, method-of-moments

A Healthcare Ethics Curriculum for MaineHealth Clinical Ethics Committees

Healthcare professionals who sit on ethics committees have widely varying experience and understanding of hospital ethics consultation resources. A curriculum for ethics committee members should provide a range of depth, breadth and flexibility to meet the needs of all ethics committee members.https://knowledgeconnection.mainehealth.org/mite/1003/thumbnail.jp

Dynamics of gender justice, conflict and social cohesion: analysing educational reforms in Pakistan

This paper analyses the role of national level reforms in school curriculum and initial teacher education in gender justice in conflict-affected Pakistan, using a multidisciplinary framework applied to multiple data sets from selected teacher education institutions in Sindh. The school curriculum texts analysed potentially perpetuate gender injustice and foster conflict. While teacher education reforms offer the potential for transformative gender justice, gender remains peripheral in initial teacher education curriculum. Furthermore, institutional practices entrench gendered norms. Lecturers’ and teachers’ limited understanding of their role and capacity for transformative gender justice pose challenges to education for gender justice, social cohesion and conflict mitigation. Informed by our understanding of gender as socially constructed, multiple strategies within and beyond education are offered towards transformative gender justice

The Interpersonal Hot Hand Fallacy: How Similarity With Previous Winners Increases Subjective Probability of Winning

Organizers of promotional or state lotteries often feature a recent winner in their advertisements, depicted by a photograph and some personal information. We show that potential participants estimate they have higher odds of winning the next drawing when featured previous winners are similar to them (on age, gender or educational background). This effect, referred to herein as the "Interpersonal Hot Hand" fallacy, then increases their participation likelihood. It disappears when respondents are given objective information on their probability of winning-rare information in the context of real-world lotteries. We identify moderating variables

Unavailable Cake on the Menu: How Phantom Compromise Alternatives Alter Indulgence Tendencies

This study shows that compromise-but-unavailable "phantom" alternatives systematically alter indulgence tendencies. Study 1 and 2 show that such alternatives can increase indulgence by reducing anticipatory guilt and regret. Studies 3 and 4 then reverse the effect by moderating hedonistic tendencies. The results implicate latent desires (those not reflected in control/baseline shares) that phantomcompromise alternatives can leverage to alter choice

For a Deeper Understanding of the Sociality That Emanates From Virtual Communities of Consumption

This paper aims to improve our understanding of the sociality that emanates from virtual communities of consumption. We have collected life narratives, with a focus on agency in consumers' experiences of forums in a virtual community of video game players. Findings reveal the existence of different means of appropriation built on identified dimensions and leading to various knowledge projects. These projects are experienced throughout subject positions around which consumers build more or less salient identities. The roles that forums play in knowledge projects lead to four main interrelated consumption logics that are collectively embodied in different ways by social practices. [to cite]
