On recalls, layoffs, variable hours, and labor adjustment costs

The paper analyzes the employment policy of a firm that can vary both hours and the level of employment. The analysis differs from previous work in the adjustment cost literature in that the firm is able to change its employment not only through hires, layoffs, and quits, but also by recalls of employees who were previously laid off. Thus, we introduce the possibility of the firm inventorying the labor input. It is shown that this labor inventory potential is necessary if the firm is to ever lay off workers. Further, it is demonstrated that linear rather than strictly convex adjustment costs are then required if the firm is to always recall employees who were previously laid off prior to hiring new workers.     

On the peer effects of star students

We estimate the effect that star students have on their siblings’ learning outcomes, measured by their high school grade point average (GPA) and their math grades. To this end, we couple administrative school data on grades with an unusual natural experiment in Peru that generates exogenous variation in the presence of star students at home. We find that star students increase their siblings’ GPA by 0.33 SDs and their math grades by 0.22 SDs. The effect size is inversely related to number of siblings, suggesting that the remaining siblings act as substitutes for the star student.     

The Financial Costs of Caring in the British Labour Market: Is There a Wage Penalty for Workers in Caring Occupations?

Recent evidence from the USA suggests that people engaged in occupations involving providing care for others, such as childcare and teaching, suffer a wage penalty. After taking into account job and individual characteristics such as level of education and work experience, people in these occupations in the American study earned about 6 per cent less than their peers in other types of occupation. However, we do not yet know if people working in similar occupations in other countries also suffer the same degree of disadvantage. The issue is important because, despite the perception that people in caring jobs place a relatively low weight on the level of remuneration when making career decisions, a number of studies have shown clear evidence of an association between pay and the propensity to give up working in a caring occupation. There are implications too for social inequality as many caring jobs are done by women and associated wage penalties could contribute to the persistent gender gap in pay. This study compares and contrasts the predictions of neoclassical economics, cultural feminist theory and social closure theory. Data are taken from 17 waves of the British Household Panel Survey and include a total of 23,773 individuals, giving 110,677 person‐year observations. These data are analysed using multi‐level linear regression. The results show clear evidence of a statistically significant wage penalty associated with working in some caring occupations. Those occupations requiring lower levels of educational qualification, such as nursing assistants and auxiliaries, are particularly hard‐hit by the wage penalty. On the other hand, some occupations, such as medicine and teaching, have fared better than comparable non‐caring occupations over the same period. We discuss the implications of these results for the gender gap in pay, poverty, social inequality and the future supply of caring workers.     

Applying search theory to determine the feasibility of eradicating an invasive population in natural environments

The detectability of invasive organisms influences the feasibility of eradicating an infestation. Search theory offers a framework for defining and measuring detectability, taking account of searcher ability, biological factors and the search environment. In this paper, search theory concepts are incorporated into a population model, and the costs of search and control are calculated as functions of the amount of search effort (the decision variable). Simulations are performed on a set of weed scenarios in a natural environment, involving different combinations of plant longevity, seed longevity and plant fecundity. Results provide preliminary estimates of the cost and duration of eradication programs to assist in prioritising weeds for control. The analysis shows that the success of an eradication program depends critically on the detectability of the target plant, the effectiveness of the control method, the labour requirements for search and control, and the germination rate of the plant.     

Textbook Treatments of the Financial Market in the IS-LM Model

Intermediate macroeconomics textbooks introduce financial markets into the IS-LM analysis but typically as a beginning-of-period consideration. Here the financial market is introduced in an end-of-period model.     

The implications of job matching for retirement health insurance and leave benefits

This paper focuses on potential reasons for variations in benefit packages, in particular variations in the availability of retirement health insurance and leave. An important feature of our analysis is that we do not start with heterogeneity in workforces to explain fringe benefit differences across employers. It would be straightforward to say that differences across employers in fringe benefit packages simply represent differences in the preferences of their workforces. Rather, we focus on heterogeneity across employers as an important source of differences in fringe benefit packages. Preliminary evidence is found supportive of the predicted differences in the likelihood of such fringe benefits as retirement health insurance and leave based upon two variables–the extent of on-the-job training offered by the employer and the size of the employers. We also examine the implied links between these fringe benefits and such variables as average tenture and the proportion of the workforce that is female.     

Cross-country differences in attitudes to business associations during the 2007–2010 recession

This paper uses empirical data gathered through an on-line survey of 206 small and medium-sized enterprises (SMEs), conducted in France, Sweden and the UK. The paper examines cross-country differences in SME managers’ perceptions of business associations as sources of political intelligence and their ability to influence policy responses to financial crises. Findings demonstrate that the respondents’ countries of origin are significantly correlated with (1) their use of information sources to gather political intelligence, (2) their perceptions regarding the effectiveness of business associations in influencing policy outcomes, and (3) their perceptions regarding policymakers’ appreciation of information provided by SME associations.
