Despite their widespread use, there is little academic evidence on whether applicant selection instruments can improve teacher hiring. We examine the relationship between two screening instruments used by Spokane Public Schools to select classroom teachers and three teacher outcomes: value added, absences, and attrition. We observe all applicants to the district (not only those who are hired), allowing us to estimate sample selection-corrected models using random tally errors and variation in the level of competition across job postings as instruments. Ratings on the screening instruments significantly predict value added in math and teacher attrition, but not absences—an increase of one standard deviation in screening scores is associated with an increase of about 0.06 standard deviations of student math achievement, and a decrease in teacher attrition of 3 percentage points. Hence the use of selection instruments appears to be a key means of improving the quality of the teacher workforce.

Public pension systems in many U.S. states face large funding shortfalls, and policymakers have considered moving toward defined contribution (DC) pension structures in the interest of reducing the likelihood of future shortfalls. Concerns exist, however, that such changes might increase levels of employee turnover. The empirical evidence on the relationship between pension structure and turnover is mixed, and is quite limited in the case of public-sector plans. The authors study a single class of public-sector employees (teachers) who are enrolled in either a traditional defined benefit (DB) plan or a hybrid DB-DC plan during overlapping periods of time. Contrary to conventional wisdom, the authors find little evidence that the introduction of the hybrid plan increased employee turnover; in fact, they find that turnover is lower among teachers who transferred out of the DB plan into the hybrid plan. Employers may benefit by shifting the debate away from plan structure per se and toward a discussion of how to provide employees with pension plans they will highly value.

This paper examines the savings behavior of public school teachers who are enrolled in a hybrid pension plan that includes a defined contribution (DC) component. Few states have incorporated DC features into teacher pension systems and little is known about how providing teachers with greater control over deferred compensation might affect their savings behavior—an important determinant of retirement security. We find the retirement savings choices of teachers—how much they opt to contribute to a DC retirement account—to be generally consistent with that of their peers in the private sector. In particular, age and salary are positively correlated with contribution rates, and contribution rates increase with teaching experience. Importantly, our analysis of retirement wealth suggests that Washington's hybrid plan is likely to provide a level of retirement security for a typical teacher that is comparable to or greater than that provided by the state's pure defined benefit plan.

Most public school teachers in the United States are enrolled in defined benefit (DB) pension plans. Using administrative microdata from four states, combined with national pension funding data, we show these plans have accumulated substantial unfunded liabilities—effectively debt—owing to previous plan operations. On average across 49 state plans, an amount that exceeds 10% of current teachers’ earnings is being set aside to pay for previously accrued pension liabilities. To the extent that the costs of the unfunded liabilities drag on teacher compensation, they may exacerbate problems of teacher recruitment and retention. We briefly discuss three policy changes that could end or reduce the accumulation of unfunded liabilities in educator pension plans: (1) transition teachers to defined-contribution retirement plans, (2) transition teachers to cash-balance retirement plans, and (3) tighten the link between funding and benefit formulas within the current defined-benefit structure.

This paper examines a natural experiment in which Washington State teachers were offered the opportunity to choose between enrolling in a traditional defined benefit (DB) plan and a hybrid plan with DB and defined contribution (DC) components. We find plan preference is weakly related to estimates of the relative financial benefits of being in either the DB or hybrid system and strongly related to teacher age. Importantly, we also find that the majority of teachers prefer the hybrid plan, and that teachers opting into the hybrid plan tend to be more effective based on student output measures of teacher productivity. These results suggest that policy shifts toward pension systems that include DC options do not necessarily make teaching a less desirable profession, particularly for the most productive employees.

This paper addresses the question of a causal link between global warming and urban sprawl by focusing on the role local climate plays in determining household behavior regarding housing decisions. We introduce a theoretical model with a climatic amenity along urban economics lines, and consider the hypothesis that under a warmer climate, households will locate in larger plots, farther away from city centers. This hypothesis is tested empirically on household data,and by controlling for selection in simultaneous equations for housing size and distance to community center. We find evidence that housing decisions on plot size and distance to the city are related to climate differences. Global warming and urban sprawl strengthen each other in a vicious circle.

Over the past two decades, the tension between public and private interests in the use of land has given rise to state-level legislation seeking to limit government controls on private property. In 2004, voters in Oregon approved Measure 37, which required payments to private landowners for reductions in the value of their property resulting from land-use regulations. The central economic question behind Measure 37 and compensation statutes adopted in other states is, what is the effect of land-use regulations on property values? Economists investigating this question have typically estimated hedonic property value models with regulations included as exogenous regressors. This approach is likely to be invalid if the parcel characteristics that determine property values also influence the government's decision about how to implement regulations. We use Regression Discontinuity Design (RDD) to study the effect of the Portland, Oregon, Urban Growth Boundary (UGB) on property values. RDD provides an unbiased estimate of the treatment effect under relatively mild conditions and is well-suited to our application because the UGB defines a sharp treatment threshold. We find a price differential on the western and southern sides of the Portland metropolitan area ranging from $30,000 to at least $140,000, but no price differential on the eastern side. Support for Measure 37 was fueled by price differences such as these among parcels subject to different regulations, but one must be careful not to view current price differentials as evidence that regulations have reduced property values.
