WANT EXPORT DIVERSIFICATION? EDUCATE THE KIDS FIRST

This paper uses Bayesian model averaging to uncover the true determinants of export diversification among 36 potential factors, and thus 2³⁶ potential models. Using data from 2001 to 2010, our results reveal two strong predictors: Primary school enrollment (99.7% posterior inclusion probability in the true model) raises export diversification, whereas the share of natural resources in gross domestic product (98.6%) lowers diversification levels. The importance of basic education coverage offers policymakers an opening toward diversifying exports, at least in the long run. This result is robust to accounting for the endogeneity of income levels by applying an instrumental variable BMA method. (JEL C11, F1, F34, O1, O2, O11)     

The Moderating Effects of National Age Stereotyping on the Relationships between Job Satisfaction and its Determinants: A Study of Older Workers across 26 Countries

This research explores how national age stereotypes impact older workers' job‐related perceptions by examining probability based samples across 26 countries taken from the European Social Survey. Multilevel data analysis was undertaken. Results show that, at the individual level, both extrinsic rewards and intrinsic rewards directly impact older workers' job satisfaction. At the country level, significant variations are found in the relationships between job satisfaction and related rewards for older workers across the 26 countries. Society's stereotypical views towards older people explained some of these cross‐country variations. This study contributes to extant literature by explicating the process by which society's age stereotypes and the meta‐stereotypes held by older workers affect how these workers make sense and take meaning out of their job‐related circumstances leading to enhanced or diminished job satisfaction. Implications highlight the need for management to be vigilant in identifying and dealing with age stereotypes in the workplace. Furthermore, managers need to be more aware of the potential harmful consequences arising from negative meta‐stereotypes and should implement strategies to tackle workplace stereotypes that would lead to negative meta‐stereotypes held by older workers.     

A new discrete distribution

A new one-parameter discrete distribution is introduced. Its mathematical properties and estimation procedures are derived. Four real data sets are used to show that the new model performs at least as well as the traditional one-parameter discrete models and other newly proposed two-parameter discrete models.     

Evaluating the power of the mann-whitney test using the bootstrap method

In this paper we evaluate the power of the Mann-Whitney test in the shift model G(x) = F (x+θ) for all x , where the distribution of G is obtained by shifting F by an amount of θ.

The bootstrap method was used to evaluate the power of the Mann-Whitney test . A comparison among the bootstrap power , the asymptotic power of the Mann-Whitney test and the t-test power proved that the bootstrap is a better technique , because , it does not require the assumption of normality.     

A new geometric first-order integer-valued autoregressive (NGINAR(1)) process

A new stationary first-order integer-valued autoregressive process with geometric marginal distributions is introduced based on negative binomial thinning. Some properties of the process are established. Estimators of the parameters of the process are obtained using the methods of conditional least squares, Yule–Walker and maximum likelihood. Also, the asymptotic properties of the estimators are derived involving their distributions. Some numerical results of the estimators are presented with a discussion to the obtained results. Real data are used and a possible application is discussed.     

Perinatal and social factors predicting caesarean birth in a 2004 Australian birth cohort

Background

The proportion of babies born by caesarean section in Australia has almost doubled over the last 25 years. Factors known to contribute to caesarean such as higher maternal age, mothers being overweight or obese, or having had a previous caesarean do not completely account for the increased rate and it is clear that other influences exist.
