Abstract:
Seemingly endless tinkering and adjustment of the structure of education in the United States over the past century has led to the adoption of different school forms at different times. Currently the middle school is the dominant form of schooling for the middle years of education; however, the middle school is a relatively new form that replaced the junior high school, which itself replaced previous schooling forms. Despite the rhetoric of policymakers and practitioners, little research has considered what school forms work for what kinds of adolescents across what dimensions. In this article, we show that for both academic and non-academic outcomes, how school systems structure the transition from 8th to 9th grade makes almost no difference. Where differences appear, they are small and point to the benefits of school transitions for providing fresh starts to adolescents in socially difficult situations. The policy implications are correspondingly clear: the optimal school structure for any school district is the one that maximizes building space, reduces crowding, and achieves administrative rationality.

12. Policymaking and Caseload Dynamics: Homeless Shelters

Abstract:
Many social problems can be understood as “conceptual caseloads”, e.g., people in poverty, and actual programmatic caseloads are a major, specific concern for policymakers and public administrators. Thus, a crucial and fairly general concern is how caseloads—whether conceptual or programmatic—can be reduced. To address this concern, officials often fall back on politically or intuitively attractive ideas—preventing people from entering caseloads, for example. Failure to incorporate caseload dynamics, however, may mean prevention and other caseload reduction policies will deliver much less than promised, and may cause caseloads to grow. In this paper, we first show how caseload size depends only on the number of entrants to a caseload and the rate at which people leave a caseload. With this framework in mind, we then address two common, seemingly appropriate policy responses: preventing entrants and hastening leaving. However, we show how too little is now known about homeless prevention to pin high hopes on its utility and that some social welfare problems, like homelessness, may be too inhospitable for prevention's logic. We then explain how allocating resources to hasten leaving is not as straightforward as policymakers have assumed but rather must recognize caseload dynamics to avoid unintended growth. We conclude by explaining some limits and opportunities in using caseload dynamics for policymaking.

13. Measuring Economic Disadvantage During Childhood: A Group-Based Modeling Approach

Abstract:
Recent research suggest that child well-being and subsequent status attainment are influenced not only by the overall magnitude of exposure to family economic disadvantage during childhood, but also by the age of exposure and significant changes in family economic circumstances. Unfortunately, traditional measures of children's economic deprivation – such as, permanent and transitory income, persistent or cumulative poverty, and the number and length of poverty spells – fail to differentiate between exposure to disadvantage at different stages in childhood and largely ignore how family economic circumstances are changing over time. In this paper we propose a new method for assessing economic disadvantage during childhood that captures both children's overall levels of exposure to economic disadvantage and their patterns of exposure. This new method, which takes advantage of recent advances in finite mixture modeling, uses a longitudinal latent class model to classify children into a limited number of groups with similar histories of exposure to family economic disadvantage. Using this new methodology, group membership can be related to both family background characteristics and achievement in childhood and early adulthood, making it possible both to assess how family characteristics affect patterns of exposure to disadvantage during childhood and directly test alternative theories about the effect of different patterns of exposure on achievement. In this paper the relationship between background factors – such as race, parental education, and family structure – and group membership is investigated, as is the association between group membership and achievement in early adulthood. The use of this technique is demonstrated using data from the Panel Study of Income Dynamics (PSID).

14. Production Markets Broker Upstream to Downstream, balancing their volume and quality sensitivities to firms through an oriented market profile of signals

Author:
Harrison C. White
Publication Date:

Working Paper

Abstract:
Varieties of quality competition across producers are extrapolated out of the two dual forms of perfect competition, oriented upstream and downstream. Only then are general, path-dependent solutions for market derived (which came first in the previous book of 2002). Attention is focused on advanced markets for high ratios of sensitivities between upstream and downstream relations of producers. Parameter identification and estimations identify impacts from substitutability with cross-stream markets as being major only for certain bands of sensitivity ratios, identified within the state space for production market contexts. Illustrative applications are sketched for strategic manipulations and investment decisions and trends in sectors.

15. Reducing Bias in Treatment Effect Estimation in Observational Studies Suffering from Missing Data

Abstract:
Matching based on estimated propensity scores (that is, the estimated conditional probability of being treated) has become an increasingly popular technique for causal inference over the past decade. By balancing observed covariates, propensity score methods reduce the risk of confounding causal processes. Estimation of propensity scores in the complete data case is generally straightforward since it uses standard methods (e.g. logistic regression or discriminant analysis) and relies on diagnostics that are relatively easy to calculate and interpret. Most studies, however, have missing data. This paper illustrates a principled approach to handling missing data when estimating propensity scores makes use of multiple imputation (MI). Placing the problem within the framework of the Rubin Causal Model makes the assumptions explicit by illustrating the interaction between the treatment assignment mechanism and the missing data mechanism. Several approaches for estimating propensity scores with incomplete data using MI are presented. Results demonstrating improved efficacy compared with existing methodology are discussed. These advantages include greater bias reduction and increased facility in model choice.

Abstract:
By analyzing data from the Current Population Survey March Supplements, Living at the Edge explores the following questions about children in low-income families in the United States: What are the overall changes in the low-income and poverty rates for children over the past quarter century? How has the population of children in low-income families changed over the past decade? Which children are more likel to live in low-income famlies? How have changes in parental employment status affected the likelihood children living in low-income families? What are the state by state variations in child low-income and poverty rates, and how have these changed in the last decade? How does a more inclusive definition of family income and expenses affect our understanding of the poverty and near-poverty rates of children in low-income families?

By analyzing data from the Current Population Survey March Supplements, Living at the Edge explores the following questions about children in low-income families in the United States: What are the overall changes in the low-income and poverty rates for children over the past quarter century? How has the population of children in low-income families changed over the past decade? Which children are more likely to live in low-income families? How have changes in parental employment status affected the likelihood of children living in low-income families? What are the state by state variations in child low-income and poverty rates, and how have these changed in the last decade? How does a more inclusive definition of family income and expenses affect our understanding of the poverty and near-poverty rates of children in low-income families? This report helps document significant improvements in the child lowincome rate as well as the significant decrease in the proportion of children who relied on public assistance during the 1990s. However, Living at the Edge also finds a notable increase in the share of children who lived in near-poor families (those with incomes between 100 and 200 percent of the poverty line) among children in low-income families during the 1990s. Many disadvantaged groups of children, including those with young parents, minority parents, parents with limited education, or unmarried parents, were less likely to live in poor or lowincome families in the late 1990s than such children a decade earlier. The improvement in the child low-income rates of these disadvantaged groups was closely related to an increase in parental employment during the late 1990s. However, the low-income rate worsened for children whose more educated parent had a high-school diploma but no college education. For children of many disadvantaged social groups, parental employment appears to do less to protect them from economic hardship then it did a decade earlier. The groups that suffered the most in reduced economic security given parental employment status were those in the medium risk ranks (children in families with at least one parent between ages 25 to 39, children whose more educated parent had only has a high school diploma, and in father-only families). The report also notes that the official measure of poverty ignores the burden of medical and work related expenses as well as taxes and therefore tends to underestimate the share of children in near-poor and low-income families facing economic insecurity. Finally, we discuss the policy implications for our findings.

18. Active Patients' in Rural African Health Care: Implications for Welfare, Policy and Privatization

Author:
Kenneth L. Leonard
Publication Date:

Working Paper

Abstract:
The 'active patient' is introduced in this paper. She is the same person as the rational peasant that we have known for at least three decades. She is a rational agent seeking health care in an environment characterized by market failures (particularly agency in the supply of medical quality) and imperfect institutional responses to these failures. We show evidence that patients significantly increase their welfare by choosing between various different providers and matching their illnesses to the resources that are available at these different providers. This paper suggests that continuing to view patients as passive participants in the health care market gives way to misleading policy suggestions and may in fact reduce the welfare of patients.

19. The Plasticity of Participation: Evidence from a Participatory Governance Experiment

Abstract:
Under the “People's Campaign for Decentralised Planning,” initiated by the government of the Indian state of Kerala in 1996, significant planning and budgetary functions that had previously been controlled by state-level ministries, were devolved to the lowest tier of government—municipalities in urban areas, and gram panchayats (village councils) in ural areas. A key element of the campaign was the requirement that every gram panchayat organize open village assemblies—called Gram Sabhas—twice a year through which citizens could participate in formulating planning priorities, goals and projects. Using data from the first two years of the campaign, on the levels and composition of participation in the Gram Sabhas in all of Kerala's 990 gram panchayats we empirically assess the explanatory power of the dominant existing paradigms of participation—social capital, rational choice, and social-historical. The basic patterns we document, as well as our more detailed analyses of the impact that a range of spatial, socioeconomic and political factors had on the levels and social depth of participation, provide broad support for a dynamic and contingent view of participation, a perspective that recognizes the “plasticity of participation.”

20. The Role of Effort Advantage in Consumer Response to Loyalty Programs: The Idiosyncratic Fit Heuristic

Abstract:
Over the past few years, customer relationship management and loyalty programs (LPs) have been widely adopted by companies and have received a great deal of attention from marketers, consultants, and, to a lesser degree, academics. In this research, we examine the effect of the level of effort required to obtain a LP's reward on consumers' perception of the LP's attractiveness. We propose that, under certain conditions, increasing the program requirements can enhance consumers' likelihood of joining the program, thus leading consumers to prefer a dominated option. Specifically, we hypothesize that consumer s often evaluate LPs based on their individual effort to obtain the reward relative to the relevant reference effort (e.g., the effort of typical other consumers). When consumers believe they have an effort advantage relative to typical others (i.e., an idiosyncratic fit with the LP), higher program requirements manify this perception of advantage and can therefore increase the overall perceived value of the program. This proposition was supported in a series of studies in which the perceived idiosyncratic fit was manipulated either by reducing the individual effort or by raising the reference effort. The findings also indicate that (a) idiosyncratic fit considerations are elicited spontaneously, (b) idiosyncratic fit mediates the effect of effort on consumer response to LPs, and (c) an alternative account for the results based on signaling is not supported. We conclude that these findings are part of a broader phenomenon, which we term the idiosyncratic fit heuristic, whereby a key factor that affects consumers' response to marketing programs and promotional offers is the perceived relative advantage or fit with the individual's idiosyncratic conditions and preferences.
