A Longitudinal Study of the Relationships Among Job Search Self-Efficacy, Job Interviews, and Employment Outcomes

Abstract: This study investigates the relationships among job search self-efficacy beliefs, number of job interviews participated in, and job search outcomes using data collected from graduating college job seekers at multiple points in their respective job searches. Results indicate that job search self-efficacy is positively related to number of total offers and number of offers from a preferred employer. Consistent with our hypothesis, job search self-efficacy beliefs moderate the relationship between number of interviews and number of offers, indicating that highly confident job seekers were more efficient in converting interviews into job offers.

Expectations Management and Beatable Targets: How do Analysts React to Explicit Earnings Guidance?

Abstract: This study investigates security analysts' reactions to public management guidance and assesses whether managers successfully guide analysts toward beatable earnings targets. We use a panel dataset between 1995 and 2001 to examine the fiscal-quarter-specific determinants of management guidance and the timing, extent, and outcomes of analysts' reactions to this guidance. We find that management guidance is more likely when analysts' initial forecasts are optimistic, and, after controlling for the level of this optimism, when analysts' forecast dispersion is low. Analysts quickly react to management guidance and they are more likely to issue final meetable or beatable earnings targets when management provides public guidance. Our evidence suggests that public management guidance plays an important role in leading analysts toward achievable earnings targets.

Nursevendor problem: personnel staffing in the presence of endogenous absenteeism

Abstract: The problem of determining nurse staffing levels in a hospital environment is a complex task because of variable patient census levels and uncertain service capacity caused by nurse absenteeism. In this paper, we combine an empirical investigation of the factors affecting nurse absenteeism rates with an analytical treatment of nurse staffing decisions using a novel variant of the newsvendor model. Using data from the emergency department of a large urban hospital, we find that absenteeism rates are consistent with nurses exhibiting an aversion to higher levels of anticipated workload. Using our empirical findings, we analyze a single-period nurse staffing problem considering both the case of constant absenteeism rate (exogenous absenteeism) as well as an absenteeism rate that is a function of the number of nurses scheduled (endogenous absenteeism). We provide characterizations of the optimal staffing levels in both situations and show that the failure to incorporate absenteeism as an endogenous effect res...
