Empirical Methodology

The study aims to empirically explore the dependence of savings behavior on demographic changes in the context of the life cycle hypothesis (LCH) in a sample of 18 European transition and post transition countries. The empirical methodology is based on a multifactor modeling approach. The research estimates heterogeneous panel data models by employing three different heterogeneous coefficient estimators: mean group (MG) estimator, common correlated effects mean group (CCEMG) estimator, and augmented mean group (AMG) estimator. The findings demonstrate that the LCH is confirmed in the case of European post-transition countries and rejected as inappropriate in European transition countries due to inconsistency of regression coefficients (age dependency, unemployment rate, urbanization, and health expenditure). The models and their findings presented in this study can be used in policymaking to predict dynamic interactions and variations among selected demographic variables in the determination of savings behavior.

The Relationship

IntroductionSuicide is a major public health problem in most of the countries because it has a high prevalence in young people. It has been studied that high levels of cortisol are associated with depression and increase of the suicidal risk.ObjectiveTo analyze the relationship between cortisol levels in a population of university students and the questionnaire results for the Beck Depression Inventory (BDI).MethodThe sample was composed by 106 students of the Nursing School of Santiago de Compostela University. The 88.7% of the sample are women with a mean age of 21.50 + /−2.52, the 99% are unmarried. The protocol consisted in 3 sections: demographic variables, BDI questionnaire with spanish scale and determination of salivary cortisol levels. Statistical analysis was done with SPSS 15.ResultsThe are higher levels of salivary cortisol in students with a greater or equal score to 13 on the BDI with statistically significances differences (p = .000). Students with suicidal ideation (item 9 of the BDI) have highest rates of cortisol, with statistically significant differences (p = 0.001).ConclusionsThis study supports other researchs about the association between biological neuroendocrine markers and affective disorders. Explaining suicidal behavior could help us to prevent it by using early intervention strategies for vulnerable populations. They could also identify markers to establish the risk of suicide.

The Impact

An ergonomic framework for conceptualizing and measuring office productivity is described. This framework is based on the the analysis of task time, posture and sequence, and the subsequent the determination of the most appropriate pace, posture, and activities for any office job. The framework assesses various measures of pace, proficiency, and posture that currently can be readily assessed by ergonomists, and it uses these measures to quantify the short-term duty cycle productivity (DCP) and in the longer-term life-cycle productivity (LCP) of office workers. The approach that will be described allows companies to evaluate the impact of ergonomic interventions on the productivity of their workers. The benefits of this ergonomic approach to assessing productivity are discussed.

Life Cycle Hypothesis

The development of financial system recently has been contributing to the economic growth of the nation. Its vital role helps many financial institutions to advance their financial services, particularly in investment systems such as Sukuk. As seen in recent years, the involvement of Sukuk in many industries ranging from sovereigns to corporates for both Muslim and non-Muslim world companies. Although its popularity increases, it seems to be widely accepted that the insufficient structures of Sukuk become a big challenge to serve the public needs to be in compliance with Shari’ah principles. In an attempt to fulfil many financial companies in issuing Sukuk and the needs of the Muslim world, this study aims to provide the new structure of Sukuk. The study proposes a design of securitization by combining two contracts of Sukuk into one Sukuk structure. The constructed idea will use a model of life cycle hypothesis to support the Sukuk issuing companies in maintaining their incomes. It also explains the cycle cash flow and asset movement as well as the calculation of Net Present Value (NPV) of the project.

Recent Idea

This study examines the dividend life-cycle hypothesis and the propensity of non-financial firms listed on the Indonesia Stock Exchange (IDX) to pay dividends, in light of a recent idea by the IDX to regulate dividend payments. Using several proxies of the life cycle, the results consistently show that Indonesian listed firms follow the dividend life-cycle hypothesis. Our results recommend that if the authority insists on regulating dividend payments, the regulation should take into account the firms’ life cycles. Firms should only be required to pay dividends when they reach a certain stage and/or meet defined characteristics, according to their stage or characteristics.

Heterogeneous Panel

In this study, the effect of real exchange rate on bilateral trade balance between Turkey and its 25 main trade partners is investigated for the period of 1996 - 2015 with heterogeneous panel data techniques. Trade balance model is estimated by using Mean Group (MG) estimator, which allows parameter heterogeneity, Common Correlated Effects Mean Group (CCEMG), and Augmented Mean Group (AMG) estimators, which both allow cross-section dependency and heterogeneity. Results indicate that the real exchange rate elasticity of the trade balance ranges between -0.40 and -0.45 and Marshall-Lerner (ML) condition is valid for Turkey. According to the results, the foreign income elasticity of trade balance ranges between 1.54 and 2.84, while for domestic income elasticity, it is found between -0.75 and -1.38. Country-specific results show that ML condition is valid for the USA, Belgium, Spain, Switzerland, Romania, and Russia at the bilateral level according to both CCEMG and AMG estimators.
