A portrait of America's children: The impact of poverty and a call to action

The responsibility for children's services is disseminated between a multitude of advocacy organizations, social service agencies, and numerous departments within our government. A lack of conceptual integration and fiscal commitment is evident at the federal, state, and local levels. The examination of poverty and children's lack of economic security, inadequate medical care, homelessness, and nutrition inadequacies reveals a portrait of America's children that is both unsettling and alarming. The paper concludes with a call for action and the commitment that will be required to rectify this problem.     

CURRENT STATUS AND RIGHT-CENSORED DATA STRUCTURES WHEN OBSERVING A MARKER AT THE CENSORING TIME

We study nonparametric estimation with two types of data structures. In the first data structure n i.i.d. copies of (C, N(C)) are observed, where N is a finite state counting process jumping at time-variables of interest and C a random monitoring time. In the second data structure n i.i.d. copies of (C ∧ T, I (T ≤ C), N(C ∧ T)) are observed, where N is a counting process with a final jump at time T (e.g., death). This data structure includes observing right-censored data on T and a marker variable at the censoring time.In these data structures, easy to compute estimators, namely (weighted)-pool-adjacent-violator estimators for the marginal distributions of the unobservable time variables, and the Kaplan-Meier estimator for the time T till the final observable event, are available. These estimators ignore seemingly important information in the data. In this paper we prove that, at many continuous data generating distributions the ad hoc estimators yield asymptotically efficient estimators of [Formula: see text]-estimable parameters.     

Cooperation in the formative years: Evidence from small enterprises in Europe

We empirically analyze factors that might affect the willingness of young small enterprises in several European countries to participate in collaborative agreements. These factors include the characteristics of the firm, of the entrepreneurs, and of the market environment the firm operates in. Within this age group – the “formative” years between 2 and 8 – firms are more likely to engage in collaboration as they grow larger, they are more innovative, they are led by educated and network-experienced entrepreneurs, and they perceive significant market risk, rapidly changing technology, and adequate IPR enforcement. They are more likely to search for collaborative opportunities when their counterparts in the same country and sector tend to do the same.     

Investigating the Effects of Mediated and Passive Prompts on Pedestrian and Bicycle Lane Adherence on a College Campus Footbridge

The current study investigated the effects of passive prompts (e.g., posted signs) and mediated prompts (e.g., spoken reminders) encouraging the lane adherence behavior of pedestrians, bicyclists, and other transportation users (i.e., skateboarders, people riding scooters, etc.) on a college campus. Results showed an increased percentage of bridge user lane adherence compared to baseline in both the mediated and passive prompting conditions, with mediated prompting yielding higher (but not significantly higher) adherence measures across sessions. The feasibility and comparative effectiveness of each prompting method are discussed.     

Auditory Stream Segregation Improves Infants' Selective Attention to Target Tones Amid Distractors

The present study examined the role of auditory stream segregation in the selective attention to target tones in infancy. Using a task adapted from Bregman and Rudnicky's (1975) study and implemented in a conditioned head-turn procedure, infant and adult listeners had to discriminate the temporal order of 2200 and 2400 Hz target tones presented alone, preceded and followed by 1460 Hz flanker tones, and presented within a series of 1460 Hz captor tones meant to release the target tones from the effects of the flankers by capturing the flankers into a separate stream. Infants showed the same pattern of discrimination across conditions as adults: discrimination of target tones in the target-alone condition, a decrease in performance when flanker tones were introduced, and a return to target-alone level in the captor condition. These results suggest that infants' perceptual organization of tones is similar to that of adults, and that their ability to selectively attend to target sounds and ignore distractors depends on the structural properties and perceptual organization of the non-target sounds.     

Changes in the Quantum of Russian Fertility During the 1980s and Early 1990s

To investigate whether Russia's dramatic fertility changes pre‐ and post‐Soviet times were due primarily to tempo effects, as has been argued recently, or to quantum effects, this study standardizes for factors that distort conventional fertility indexes. A time series spanning 1978–93 of period parity‐progression ratios for the Russian Federation is constructed applying the PADTFR technique, which takes into account age, parity, and time elapsed since the birth of the previous child, to data from the Russian micro census of February 1994 (2.8 million maternity histories). Both the fertility rise of the 1980s and the fertility fall of the early 1990s are found to be primarily due to changes in the probability of a second birth. The impact of tempo on the conventional TFR is significant, but of relatively minor magnitude in comparison to changes in the quantum of fertility. The social and economic context in which the fertility change took place is described.     

JEEA‐FBBVA LECTURE 2013: THE NEW EMPIRICAL ECONOMICS OF MANAGEMENT

Over the last decade the World Management Survey (WMS) has collected firm‐level management practices data across multiple sectors and countries. We developed the survey to try to explain the large and persistent total factor productivity (TFP) differences across firms and countries. This review paper discusses what has been learned empirically and theoretically from the WMS and other recent work on management practices. Our preliminary results suggest that about a quarter of cross‐country and within‐country TFP gaps can be accounted for by management practices. Management seems to matter both qualitatively and quantitatively for performance at the level of the firm and the nation. Competition, governance, human capital, and informational frictions help account for the variation in management. We make some suggestions for both policy and future research.     

Homeless Youth: Patterns of Belief

Public policies, as Edelman (1977) has pointed out ‘rest on the beliefs and perceptions of those who help to make them’. Policy on youth homelessness is no exception. A full understanding of youth homelessness. it is argued, requires an understanding of the belief systems of those who define the problem and who shape policy. This paper reports the results of a study of the perceptions of policy makers and the providers of services to youth.
