Executive Compensation, Performance, Board and Ownership Structure: a Simultaneous Equations Approach.

Incentive contracts and monitoring by boards of directors and blockholders are alternative internal mechanisms to ensure that managers act in the interests of shareholders. Most prior research on compensation and performance ignores endogeneity among board, ownership and compensation structure (mix of pay) variables. Ignoring the endogeneity leads to inconsistent parameter estimates. I address the endogeneity problem by using a simultaneous equations model. The three equations in the system are mix of pay, compensation and performance. The results are consistent with efficient contracting. Mix of pay depends on characteristics of the firm and alternative governance mechanisms. The relation between stockholders and debtholders affects the relation between managers and stockholders. Financial leverage has a significant effect on mix of pay. Compensation and performance equations show that mix of pay is endogenous and belongs in both equations as an explanatory variable. Mix of pay is significantly positive in the compensation equation, consistent with the prediction that higher incentive based compensation leads to higher compensation risk and hence higher compensation. Neither mix of pay nor the board and ownership variables is significant in the performance equation, suggesting that firms choose optimal combinations of governance mechanisms. The direct effect of regulation on compensation reported in prior studies is spurious. The evidence provided shows that this effect is caused by omitting mix of pay from the compensation equation

Factors Affecting Diffusion and Adoption of Agricultural Innovations Among Farmers in Ethiopia Case Study of Ormia Regional State Western Shewa

The contribution of new technology to economic growth can only be realized when and if the new technology is widely diffused and used. Diffusion itself results from a series of individual decisions to begin using the new technology, decisions which are often the result of a comparison of the uncertain benefits of the new invention with the uncertain costs of adopting it. An understanding of the factors affecting this choice is essential both for economists studying the determinants of growth and for the generators and disseminators of such technologies. The study was to determine the factors affecting farmer’s adoption of improved agricultural innovation in Welmera district western part of Oromia regional state Ethiopia. Non replaceable lottery method and proportional to size sampling techniques were employed for the selection of 130 respondents; structural questionnaires and group discussion were used. Data were analyzed using Statistical tests like chi-square, t-test, one way ANOVA and econometric model Tobit was used to identify the effect of the hypothesized variables on the dependent variable . The result of the econometric model indicated that educational level of respondent, total land holding, accesses to research and access to extension were found significant to influence adoption of improved potato production packages. The mean average age of sample respondent was 45-54. The independent t-test result shows that there was no significant difference between adopter categories in terms of age to the adoption of improved potato technology (t=1.747, p 0.991). From the sample household heads 13.85% of respondent farmers are illiterate and the remaining 86.15% are educated. Majority of high adopters have been educated from grade 5 to 10 Chi-square test also shows the significant difference between adopter categories of improved potato technologies (χ2=17.25a, P=0.004). It is time to look participatory extension approach which invites different stakeholders. FRG approach contributed significant role in the diffusion and adoption of agricultural innovations.

Preoperative anxiety among adult patients undergoing elective surgery: a prospective survey at a general hospital in Ethiopia.

BackgroundMajor life changes are among factors that cause anxiety, and one of these changes is surgery. Hospitalization, regardless of disease, is known to provoke anxiety in the patient admitted for surgery. Anxiety is an unpleasant disturbing experience that involves way of thinking of tension, apprehension, uneasiness and high autonomic activity. Patients with high levels of anxiety require higher doses of anesthetic induction agents and recover poorly. The objective of this study was to investigate the prevalence of preoperative anxiety and its predictors among adult patients scheduled for elective surgery.MethodologyInstitutional based cross sectional study was conducted using interviewer administered structured questionnaire in Yirgalem zonal hospital in Ethiopia from November 1, to December 30, 2018 on 407 patients scheduled for elective surgery. The study included all patients with age greater than 18 years who were undergoing surgery. Patients with known anxiety disorder and unable to communicate were excluded from the study. State and trait anxiety inventory (STAI) measurement scale was used to assess preoperative anxiety. Statistical analysis was performed using SPSS version 22. Binary logistic regression analysis was performed to determine the predictors of preoperative anxiety. The strength of the association was presented using AOR with 95% confidence interval and p-value ResultsAmong a total of 402 patients enrolled in the study 228 (56.7%) were male. The prevalence of preoperative anxiety among scheduled patients for elective surgery was 47.0%. Having strong social support (AOR = .16 CI = 0.07, 0.34), harm from doctor or nurse mistake (AOR = 5.03, CI = 2.85, 8.89), unexpected result of operation (AOR = 3.03, CI = 1.73, 5.19), unable to recover (AOR = 2.96, CI = 1.18, 4.87), and need of blood transfusion (AOR = 2.76, CI = 1.65, 4.62) were significantly associated with preoperative anxiety.ConclusionIn the current study the prevalence of preoperative anxiety was high (47%). Having strong social support, unexpected result of operation, harm from doctor or nurse mistake, need of blood transfusion, and unable to recover were found to be statistically significant for preoperative anxiety. Patients need to be assessed regularly for anxiety during the preoperative visit

Implicit prices of indigenous cattle traits in central Ethiopia: Application of revealed and stated preference approaches

The diversity of animal genetic resources has a quasi-public good nature that makes market prices inadequate indicator of its economic worth. Applying the characteristics theory of value, this research estimated the relative economic worth of the attributes of cattle genetic resources in central Ethiopia. Transaction level data were collected over four seasons in a year and choice experiment survey was done in five markets to generate data on both revealed and stated preferences of cattle buyers. Heteroscedasticity efficient estimation and random parameters logit were employed to analyse the data. The results essentially show that attributes related to the subsistence functions of cattle are more valued than attributes that directly influence marketable products of the animals. The findings imply the strong need to invest on improvement of attributes of cattle in the study area that enhance the subsistence functions of cattle that their owners accord higher priority to support their livelihoods than they do to tradable products

Social Anxiety Disorder Among Undergraduate Students of Hawassa University, College of Medicine and Health Sciences, Ethiopia.

Introduction:Social anxiety disorder (SAD), also called social phobia, is an uncontrollable fear of social situations, which involve fear of observation or making contact with strangers. So, helping individuals with social anxiety, which is among the factors affecting mental health, can significantly influence a students' mental health and prevent other problems. Objective:The study aimed at assessing the magnitude of SAD and its determinants among undergraduate students of Hawassa University, College of Medicine and Health Sciences. Methods:An institution based cross-sectional study was conducted from April 1 to May 30, 2018, in Hawassa University, College of Medicine and Health Sciences. We selected participants by a stratified random sampling method, and we collected data independently from each stratum (department) using a 17 item self-rating Social Phobia Inventory (SPIN) scale to assess SAD. We performed multiple logistic regression analysis to find factors associated with SAD. Results:Out of 304 students, 293 completed the questionnaire, with a response rate of 96.3%. The mean age of the participants was 22.13 years with a standard deviation of ± 2.176, and 172 (58.7%) were males. The prevalence of SAD was 32.8%. Family history of mental illness (AOR=4.72, 95% CI (1.25, 17.74)), being a 3rd-year student (AOR=0.178, 95% CI (0.055, 0.57)) and being a 4th year student (AOR=0.15, 95% CI (0.049, 0.49)) were significantly associated with SAD. Conclusion:This study showed a high prevalence of SAD among medicine and health science students of Hawassa University. Therefore, the Ethiopian Ministry of Higher Education and university officials need to draw up a plan to reduce social phobia

Global Estimates of the Prevalence of Depression among Prisoners: A Systematic Review and Meta-analysis.

BackgroundPrison populations tend to be marginalized and disadvantaged of the rights and freedoms that other people in the community benefit from. Their separation from families, a narrow room and lack of privacy in the prison, violence between prisoners, and the uncertainty about the future result in psychological distress, for example, depression. The review has synthesized previous studies conducted on the topic and summarized to formulate recommendations for future prison health care services.MethodsWe systematically searched the databases: PubMed, Psych Info, and SCOPUS, as well as manual Google Scholar searches, were conducted to retrieve published literature globally. We have included observational studies, written in English language. Estimates were pooled using a random-effects model. The study protocol was registered in PROSPERO with protocol number CRD42020156108. Subgroup and sensitivity analysis was conducted, and heterogeneity across the studies was evaluated using Q and the I 2-test. Publication bias was assessed by inspection of the funnel plot and Egger's regression test.ResultA total of 1313 studies were initially identified through the electronic database; among these, a total of 73 full-text articles were retrieved for further appraisal. Further, 32 full-text articles were included in the final systematic review and meta-analysis. In this meta-analysis, the pooled prevalence of depression among prisoners was 36.9% (95% CI; 27.3-47.6). The pooled prevalence of depression among prisoners in the developing and developed countries was 39.2% and 33.1%, respectively. Moreover, the prevalence of depression was 19.1% and 54% for the studies that used diagnostic and screen tools to diagnose or screen depression, respectively. A leave-one-out analysis revealed that the pooled prevalence of depression among prisoners was not dependent on a single study removal or addition. Thus, the pooled prevalence of depression ranges between 35.3 and 38.0%.ConclusionThe prevalence of depression among prisoners was high. Therefore, regular and continuous screening of depressive symptoms for prisoners along with its appropriate management is highly recommended
