Competitive bidding — The probability of winning

A company bidding by sealed tender needs to know the relationship between their bid price and their chances of winning the contract. Previously published models for computing the probability of winning are examined and found to be inaccurate. The problem is reformulated, and a new general predictive model for computing the probability of winning is developed. The method of computation is illustrated by a simple worked example.     

Do single mothers in the United States use the Earned Income Tax Credit to reduce unsecured debt?

The Earned Income Tax Credit (EITC) is a refundable credit for low-income workers mainly targeted at families with children. This study uses the Survey of Income and Program Participation’s topical modules on Assets and Liabilities to examine associations between the EITC expansions during the early 1990s and the unsecured debt of the households of single mothers. We use two difference-in-differences comparisons over the study period 1988–1999, first comparing single mothers to single childless women, and then comparing single mothers with two or more children to single mothers with exactly one child. In both cases we find that the EITC expansions are associated with a relative decline in the unsecured debt of affected households of single mothers. While not direct evidence of a causal relationship, this is suggestive evidence that single mothers may have used part of their EITC to limit the growth of their unsecured debt during this period.     

Harmful care. To what extent is terminology from medicine and clinical psychology applicable to out‐of‐home care?

Research concerning outcomes for children who have been placed in out‐of‐home care has indicated that the care may have unwanted consequences. However, there has been no coherent terminology for differentiating between different types of such unwanted consequences. In this article therefore, we attempt to disentangle different aspects of potentially harmful care for looked after children, as well as to discuss potential pathways to more systematically approach and report adverse events for this group. In this endeavour, we turn to two adjacent disciplines, medicine and psychology, where these issues have received more interest. The applicability of the concepts used in these fields is discussed, and it is concluded that although they provide some help in categorizing different aspects of harmful care, the complexity of out‐of‐home care makes existing models difficult to adopt without adjustments. This has consequences for the possibility of evaluating care in research, as well as for monitoring adverse events in practice. Importantly, the causality will often be unknown. We therefore suggest that it is essential to shed more light on how decisions should be made about when to intervene or not in out‐of‐home care, despite limited information.     

Productivity of highly skilled immigrants: economists in the postwar period

Prior work finds declining immigrant quality in the postwar period that is linked to source-country and skill-composition changes associated with the 1965 Immigration Act. This paper uses a unique panel of foreign- and native-born American Economic Association members to show that the highly skilled experienced a similar shift away from European migrants toward those from Asia. However, the findings do not indicate that this change in source-country composition has been accompanied by a decline in quality; rather, the most recent cohorts of foreign-born economists appear to be more productive than their native counterparts.     

“Starting Points Matter”: Humanizing Economics Pedagogy through New Economic Paradigms

Abstract

This paper considers the implications of the neoclassical dominant narrative in economics education and conceptualizes specific responses that teachers and teacher educators can take to promote a humanizing economics pedagogy. I briefly describe alternative economic paradigms and contrast them with neoclassical fundamentals. Then, I include economic lesson ideas to showcase ways to teach traditional economic content in ways that attend to neoclassicism but expand the potential of the discipline into new paradigms. By interrogating the fundamentals of neoclassical economics, students and teachers of economics can use these new economic paradigms to foster a counternarrative that is more critical and humanizing and can help address the prevailing themes of an era marked by systemic oppression.     

Impression management in the market for residential care for children and youth in Sweden

In what has become quite a turbulent quasi‐market for residential care for children and youth, providers now compete for public contracts. To create visibility and attract customers, many providers use marketing activities to project the desired impression of themselves to maintain or strengthen their market position. In this article, we analyse how companies that provide residential care for children manage the impressions they project on their websites and in advertisements. The results reveal that residential care providers use a range of impression management strategies to enhance their organizational image and to respond to potentially damaging or threatening images. The information providers choose to disclose leaves customers—in this case, the social workers responsible for choosing and purchasing care on behalf of clients—with rather limited opportunities to evaluate the quality of care. This is a significant problem considering other, more reliable, sources of information are difficult to access.     

Rolling with the shakes: an insight into teenagers’ perceptions of recovery after the Canterbury earthquakes

Natural disasters are harmful worldwide events that inflict multiple psychosocial impacts on disaster-exposed individuals. A significant proportion of affected individuals are teenagers (13–18 years old) who, compared with adults, have been historically overlooked in disaster research. The literature is particularly sparse concerning teenagers’ recovery from natural disasters, specifically what recovery means to them and the contributing factors towards their positive recovery. Therefore, the aim of the current study was to gain deeper insight into this largely unexplored area by conducting five focus groups with teenagers (16–18 years) who experienced at least one of the Canterbury, New Zealand, earthquakes since and including the initial September 2010 earthquake. This study directly asked teenagers about their recovery over the three years after the initial earthquakes, with data being analysed using thematic analysis. Two main themes were identified: (1) perceptions of recovery, with three sub-themes (i) knowledge and being less frightened, (ii) talking about the earthquakes and (iii) shift in perspectives; and (2) contributing factors to recovery, with three sub-themes (i) participation in the community response, (ii) returning to school and (iii) the rebuild of Christchurch. These factors provide insight into how we can better support the recovery process for disaster-exposed teenagers to reduce long-term distress.     

A common-features analysis of Amsterdam and London financial markets during the eighteenth century

We examine the financial linkage between the London and Amsterdam financial markets using stock prices recorded in each market over the period 1723-94 in conjunction with tests for common trends, cycles, and regime shifts. These tests reveal a surprising degree of integration between the markets as their prices move together in both the short and long run. Moreover, shocks to the assets translate quickly and accurately between markets. It also appears that Dutch investment did not destabilize London markets and stock prices in London were the primary determinant of prices in Amsterdam.     

Parental Expectations and Educational Outcomes for Young African American Adults: Do Household Assets Matter?

African American children are more likely to be poor and live in households that are “asset poor,” with no or very little net worth. Using the Panel Study of Income Dynamics and its Child Development Supplement, this article explores whether living in a household with net worth above the sample median seems to promote educational success and the development of human capital over time, irrespective of income. Controlling for parental income and education, as well as gender, household wealth in the form of net worth was the best predictor of parental expectations, high school completion, and college enrollment for young African American adults. A brief discussion of possible asset-building policy options follows.
