Abstract:
This study aims to investigate the effects of personality traits, in addition to basic financial literacy, private pension literacy and behavioural factors on Private Pension System (PPS) participation using machine learning algorithms. The PPS participation model was trained using both random forest and LightGBM algorithms, and the contributions of model inputs in the prediction of pension participation were interpreted using the Tree SHAP algorithms with swarmplots. The data employed in the empirical analysis is survey data collected from the Şırnak province of Türkiye with a sample size of 449. The findings of the study shows that: (i) PPS participation is more likely for females and middle-aged people; (ii) High basic financial literacy has a negative impact on PPS participation; (iii) Extraversion is the key personality trait affecting PPS participation; (iv) Advanced pension literacy has more impact on participation than simple pension literacy: (v) Present-fatalistic tendency is key behavioural factor and it negatively affects PPS; (vi) Present-hedonistic, conscientiousness, future-time orientation, and locus of control tendencies increase PPS participation. Furthermore, the distribution of colours in LightGBM has a greater degree of uniformity in both directions compared with the random forest algorithm. Finally, to increase PPS participation, the results of the study suggest the implementation of the following policy measures: Tailored pension literacy programmes can help to increase pension participation rates. Incentives should be created to prevent narrow-minded behaviour and establish a sense of protection and control around PPS, targeting middle-aged individuals and women.

All the students enrolled in public and private universities of the Punjab were population of the study. Sample was comprised of 500 students which were selected through convenient sampling technique. Due to Covid-19 convenient sampling technique was used. Two instruments were used to measure personality traits and procrastination. Big Five Inventory was used to measure personality traits and 20-item Procrastination Scale was used to measure procrastination. Structural Equation Modeling (SEM) was used to analyze the data. It was found that sample data fit the hypothetical model well. Randomly selected large sample is recommended to further probe the cause-effect relationship of variables understudy.

Abstract:
Do leadership attributes change/persist with experience in office, and after a dramatic event? Answers to this agent-structure question represent the main division line between dispositional and situational theorists. While the first posits that leader’s actions are a product of configuration imposed by experience, and traumatic events, the latter focuses on persistent set of beliefs in leaders. This paper aims at testing the role of these two variables, experience, and traumatic event, on the personality of political leaders with a special focus on Recep Tayyip Erdogan. To recover the personality attributes of Erdogan, and measure their resilience or weakness against experience and traumatic events, the paper uses Leadership Trait Analysis (LTA) developed by Margaret Hermann. LTA assumes that leaders’ choice of certain words in public speeches reflects their personality traits, through which they can be compared with other leaders, and even themselves in different roles and times.

Abstract:
What is the long run impact on development from di§erences in subsistence strategies during preindustrial times? Whereas this question has been explored from the point of view of agriculture, remarkably little attention has been paid to the complementary strategy of relying on marine resources. As a step towards closing this gap, we construct an index ñìthe Bounty of the Sea index ñwhich captures the potential abundance of exploitable marine Ösh that individual countries have had access to, and proceed to explore its correlation with economic development. Our analysis reveals that a greater Bounty of the Sea stimulated pre-industrial development, and that countries inhabited by people with ancestry in regions with abundant marine resources are richer today. Probing possible underlying reasons, we Önd that populations with ancestry in regions rich in marine resources di§er from societies with a purely agrarian legacy in terms of institutions, cultural values and average personality traits.
