SUBSIDIZING ALTRUISM IN LIVING ORGAN DONATION

The current supply of deceased donor organs is insufficient to meet the growing demand for transplantable organs. Consequently, candidates for kidney transplantation are encouraged to find a living donor. In 2008, the Department of Health and Human Services began to reimburse donors' travel‐related expenses via the National Living Donor Assistance Center (NLDAC). Using variation in transplant centers' applications for donor assistance, we use a difference‐in‐difference model to estimate the relationship between the NLDAC and living donor kidney transplants. We find that among participating transplant centers, the program increased the number of living donor kidney transplants by approximately 14%. (JEL I12, I18, D64)

Enrolment in Labour Market Training Programmes

ABSTRACT: The specification of a model for selection to labour market training is studied. Based on present value maximization, it is demonstrated that frequently adopted specifications of wage equations yield selection models containing a difference between alternative wage rates paid in the training period. In addition, the training effect on future wage rates can be sign determined. Using this, we test the hypothesis of present value maximization. A test that is robust against omitted variables and heteroskedasticity is used. Based on a sample of unemployed Swedish workers, we find positive training effects for most sub-groups.     

A Model for Planning Resource Requirements in Health Care Organizations

In this paper we present a general model and solution methodology for planning resource requirements (i.e., capacity) in health care organizations. To illustrate the general model, we consider two specific applications: a blood bank and a health maintenance organization (HMO). The blood bank capacity planning problem involves determining the number of donor beds required and determining the size of the nursing and support staff necessary. Capacity must be sufficient to handle the expected number of blood donors without causing excessive donor waiting times. Similar staff, equipment, and service level decisions arise in the HMO capacity planning problem. To determine resource requirements, we develop an optimization/queueing network model that minimizes capacity costs while controlling customer service by enforcing a set of performance constraints, such as setting an upper limit on the expected time a patient spends in the system. The queueing network model allows us to capture the stochastic behavior of health care systems and to measure customer service levels within the optimization framework.     

Physical activity assessment and health outcomes in old age: how valid are dose–response relationships in epidemiologic studies?

In this systematic review the validity of the dose–response relationships between physical activity (PA) and energy expenditure (EE) on defined health outcomes (cardio- and cerebrovascular morbidity and mortality, cancer) for the elderly is questioned. Medline, Cochrane, and EMBASE databases were reviewed for epidemiological longitudinal studies in populations aged 60+ for the years 1985–2007. Although most of the 18 identified studies generally demonstrated an inverse dose–response relationship between PA and EE level with morbidity and mortality, the range of dose–responses was remarkably broad. The nature of the dose–response relationship remained unclear. PA questionnaires - even those constructed for the elderly - do not cover the extremely diverse aspects of age-specific PA behavior and modes of muscular activity. Only non-age-specific tables had been used to estimate the EE in the elderly. Direct measurements of EE were limited. The results have implications for the interpretation of the dose–response relationships between PA and EE on defined health outcomes in old age.     

Assessing the Measurement and Structure of Material Hardship in the United States

Previous attempts to measure material well-being or hardship have not made clear the relationship of individual items to the broader concept of hardship. The current study used the Survey of Income and Program Participation (SIPP), a large-scale U.S. survey with a large number of questions on the material circumstances of households to create a measurement model of hardship that takes this relationship into account. A higher-order model with five-first-order factors: consumer durables, resources available to meet needs, housing conditions, neighborhood problems and crime, and community services, and a single second-order factor hardship fit the data well, with the “Housing” and “Neighborhood” first-order factors most strongly related to the higher-order hardship construct. Despite our attempts to tie the hardship measures to objective conditions, subjective evaluations were strongly related to most of the factors.
