This paper uses micro-level data from a nationally representative survey of 22,000 individuals in 14 Eastern European countries to investigate the effects of institutional, social, and individual factors on taxpayers' perceptions of power, motivations to comply, and non-compliant behaviors. The results indicate that institutional, social, and individual aspects shape taxpayer behavior: attitudes of peers, individual compliance norms, and the tax burden impact on non-compliance. Moreover, I find several effects of the subjective appraisal of the interaction with tax administrations. Positive experiences strengthen perceptions of power and intrinsic motivations to comply. They also increase the propensity to report non-compliant behavior in the past, suggesting educational effects of taxpayer services and tax audits.

The importance of studying challenges in implementing information technology solutions in health care organizations is highlighted by the huge investments in health care information technology (HIT) which has been spurred by recent government mandates. Information technology can help improve health care delivery cost by facilitating the standardization of work processes or routines and reducing variations among them. Set in a premier 950+ bed hospital in the south eastern part of US, this dissertation consists of two studies examining the challenges involved in implementing HIT solutions. In the first study, we seek to gain deep insights into how the process of creating a patient’s chart evolves over time in a health care institution. The second study focuses on the users of Electronic Health Records (EHR) system, investigating the compliance behavior of various providers with respect to patient records in the system. In the first study, through the lens of Activity theory our results show that the charting routine is implicated by the following environmental factors: (1) Tools, (2) Rules, (3) Community, and (4) Roles, and by individual factors: (5) Computer Self-Efficacy and (6) Risk Propensity. In the second study, our results indicate that there is a substantial effect of subculture of the different occupational groups on IT security compliance intent and behavior in a health care institution.
