We derive a closed form expression for the asymptotic distribution of the LIML estimator for the coefficients of both endogenous and exogenous variables in a partially identified linear structural equation. We extend previous results of Phillips (1989) and Choi and Phillips (1992) where the focus was on IV estimators. We show that partial failure of identification affects the LIML in that its m...

social apathy refers to avoidance from participation in social problems, discouragement and disinterest, civic disinvolvement and being inattentive to social, political, cultural subjects and social alienation happens when the individuals in relation to self, others and society at diverse forms feel powerless, abnormal, meaningless, socially isolated or hate the culture or themselves. the main ...

What is the weak instruments (WI) problem and what causes it? Universal agreement does not exist on these questions. We define weak instruments by two features: (1) 2SLS is badly biased toward the OLS estimate and alternative “unbiased” estimators such as LIML may not solve the problem and (2) the standard (first order) asymptotic distribution does not give an accurate framework for inference. ...

Background: The high workload of nurses in hospitals has been identified as a patient safety and worker stress problem. Psychological empowerment is a motivational concept demonstrated in four dimensions: meaning, competence, self-determination, and impact. Objective: This study investigated the relationship between nurses’ workloads and psychological emp...

introduction: ethical climate is a part of organizational culture. organizational values deal with ethical issues and determine what is considered ethically correct. the ethical climate of an organization can predict unethical and ethical behaviors. this study aimed to investigate and model the structural equations between the intention to quit and ethical climate, job satisfaction, and organiz...

results the results show that the individual and demographic factor (idf), organizational factor (of), h & s training factor (tf), workplace-human factor (whf), factor related to type of accident occurrence (taf), h & s risk management system factor (rmsf), and accident time factor (atf) were considered to be effective and significant independent latent factors in occupational injuries. conclus...
