A Polynomial Logistic Distribution and its Applications in Finance

The importance of Logistic distribution has been widely recognized in many applied areas such as, demography, population studies, finance, agriculture, etc. Since its introduction as a model, much attention has been paid to the study of several generalizations of it, which would offer additional flexibility when data fitting is chased. In the present paper we introduce and develop a natural generalization of the Logistic distribution by considering a probability model whose logit cumulative distribution function transformation is of polynomial type. The performance of the model's fitting to financial data, using different parameter estimation methods, is also investigated.     

The effect of delaying motherhood on the second childbirth in Europe

We examine the effect of delaying motherhood on the transition to the second childbirth across European countries. There exist two opposite forces of delaying the first birth: biological and socio-cultural factors producing a postponement effect and career-related factors leading to a catch-up effect. Estimating a multistate duration model that addresses the endogeneity of age at first birth, we find a catch-up effect in countries where the career effect is large and a postponement effect in countries where the opportunity cost of childbearing is relatively high due to the lack of family friendly institutions and cultural influences, which may discourage late childbearing.     

Supply chain reconfiguration opportunities arising from additive manufacturing technologies in the digital era

Abstract

The aim of this study is to explore the impact of additive manufacturing (AM) technologies on the configuration opportunities of supply chains (SCs) within the digital manufacturing era. To this effect, we first conduct a critical taxonomy of existing research efforts and then propose an integrated decision-making process for the design and management of SCs defined by digital manufacturing technologies. Following, we provide an integrated framework for future SC reconfiguration opportunities arising from the adoption of AM on a supply network setting. Our analysis demonstrates the significant ramifications of AM techniques on SC configuration and sustainability performance as opposed to conventional value networks; however, existing research is evidently limited due to scope related challenges and the inherent complexity at the manufacturing echelon of the respective supply networks.     

Likelihood‐based inference for correlated diffusions

The authors address the problem of likelihood‐based inference for correlated diffusions. Such a task presents two issues; the positive definite constraints of the diffusion matrix and the likelihood intractability. The first issue is handled by using the Cholesky factorization on the diffusion matrix. To deal with the likelihood unavailability, a generalization of the data augmentation framework of Roberts and Stramer [Roberts and Stramer (2001) Biometrika 88(3), 603–621] to d‐dimensional correlated diffusions, including multivariate stochastic volatility models, is given. The methodology is illustrated through simulated and real data sets. The Canadian Journal of Statistics 39: 52–72; 2011 © 2011 Statistical Society of Canada     

(De)mobilising and (mis)representing ‘youth’ in the Chinese workplace: political dependency,generational subordination and corporatisation in the Communist Youth League

The Chinese Communist Party’s (CCP) youth organisation, the Communist Youth League (CYL, League), has an extensive grassroots network and approximately twelve million members in public and partially state-owned sectors of the economy, as well as a political mandate to promote ‘youth’ interests at work. This article examines the League’s operation in the Chinese workplace by analyzing qualitative data collected during fieldwork in twelve different sites in Beijing and Zhejiang province. It was hypothesised that as League organisations are under pressure to represent youth-specific demands, their response would be similar to the Trade Unions, which try to simultaneously remain loyal to pro-management Party committees and act as grassroots channels for advocacy. The article finds that League cadres occupy junior positions in political, generational and workplace hierarchies resulting to their multifaceted subordination to more senior power holders present, namely the management, Party Committee and Union leadership. The institutionalised ‘juniority’ of cadres creates strong disincentives for pro-youth employee initiatives and leads to the disarticulation of a distinctive ‘youth’ agenda. This institutional ‘gap’ in workplace representation has direct implications both for the welfare of young employees and for the future of industrial relations in China.     

Exploring the distribution for the estimator of Rosenthal's ‘fail-safe’ number of unpublished studies in meta-analysis

The present article discusses the statistical distribution for the estimator of Rosenthal's ‘file-drawer’ number N_R, which is an estimator of unpublished studies in meta-analysis. We calculate the probability distribution function of N_R. This is achieved based on the central limit theorem and the proposition that certain components of the estimator N_R follow a half-normal distribution, derived from the standard normal distribution. Our proposed distributions are supported by simulations and investigation of convergence.     

Youth‐oriented active labour market policies and economic crisis: Explaining policy effort in Greece and Portugal

The starting point of this study is the implementation of seemingly similar youth‐oriented labour market policies in Greece and Portugal. Both countries have suffered high youth unemployment rates and have been pressured to restructure their labour market as part of the rescue programmes adopted during the European sovereign debt crisis. Despite convergence in terms of policy trajectories, there is a significant divergence in employment outcomes. In Portugal, youth‐oriented policies were better‐targeted and structured. Their implementation has been more effective and has involved the social partners from the outset of the crisis. In Greece, policy design failures, administrative weaknesses and unfavourable macroeconomic conditions have limited the dynamics of youth‐oriented policies thus increasing youth insecurity. Τhe analysis suggests that convergence in policy content can be compatible with divergence in terms of outcomes.     

THE INTERNATIONAL TRANSMISSION OF VOLATILITY SHOCKS: AN EMPIRICAL ANALYSIS

This paper proposes an empirical model which can be used to estimate the international transmission of volatility shocks. Using this model we estimate that a one standard deviation increase in the volatility of the shock to US real GDP leads to a decline in UK GDP of 1% relative to trend and a 0.7% increase in UK CPI relative to trend at the two‐year horizon. Using a nonlinear open‐economy DSGE model, we find that these empirical estimates are consistent with the response to a perturbation to the volatility of foreign “supply” type shocks, while an increase in the volatility of demand shocks has a negligible impact.     

Behavioral Channels in the Cross‐Market Diffusion of Major Terrorism Shocks

The diffusion mechanism of terrorist shocks to third countries’ stock market responses is explored by employing a Heckit model. Stock market response is broken down to (i) the direction of reaction and (ii) conditional on negative reaction, its magnitude. The analysis puts forward two behavioral factors (memory‐based utility/availability heuristic, social amplification of risk), proxied by past terrorism record and terrorism risk concern as the shocks’ diffusion channels. The findings are that the likelihood and the size of negative stock market reaction increase with terrorism record and risk concern. Additionally, weak evidence is uncovered for a mitigation of risk concern's impact by favorable macroeconomic stance. Furthermore, the impact of behavioral factors, especially over the magnitude of reaction, is robust when controlling for economic linkages. The latter are also significant predictors of the direction of stock market reaction, but not of its magnitude.
