Cost-effective care a phone call away: a nurse-managed telephonic program for patients with chronic heart failure

Health care providers and health care systems are challenged to find cost-effective ways to address the costs associated with heart failure. A multidisciplinary team of nurses, physicians, pharmacists, and dieticians was assembled at New Hanover Regional Medical Center (Wilmington, NC) to develop strategies to decrease the readmission rate without compromising patient care. The team developed a disease management program that included comprehensive inpatient education, as well as an outpatient telephonic program to reinforce education after discharge. Goals were to reduce readmissions of patients with heart failure, to decrease the cost per case of each patient with chronic heart failure, and to reduce the length of stay for patients who were readmitted. The CHF Telephonic Program was extremely successful in meeting patient-focused and organizational goals related to readmissions, length of stay, and cost of care.     

Improving the participation of smallholder mango farmers in modern retail channels in Indonesia

Demand for fresh fruits and vegetables in Indonesia has been continuously growing as the result of increasing incomes, high growth of the urban population, and modern retail development. The growth of modern retail chains in Indonesia in the last few decades has intrigued some development experts and practitioners because it had been expected to provide greater opportunities for linking small farmers to high value globalized market chains. The modern private sector would, it was hoped, incorporate small producers with the goal of both securing supply and contributing to poverty reduction. However, in terms of mangoes, previous studies have indicated that only a very small proportion of local production is marketed to modern retail chains and/or exported. The main objective of this study is to identify the factors affecting farmers' participation in modernizing retail channels. The study randomly selected 636 mango farmers from the two main mango production zones in Indonesia, West Java and East Java provinces. The study shows that an expansion of the modernized retail segment has not always benefitted local producers, especially smallholder farmers. It is demonstrated that smallholder farmer participation could be higher when the level of commercialization in the market is high and/or retail procurement was already more modernized. Factors that increase farmer capacity to participate in the modern retail chain are irrigation, farm tools, and infrastructure. To increase smallholder farmer participation, the study suggests a policy of encouraging enforcement of quality standards at wholesale markets, technical assistance to farmers relating to value-adding postharvest activities, and improvements in rural infrastructure.     

The Subprime Mortgage Calamity and the African American Woman

Many media and scholarly reports have focused on the subprime mortgage crisis and the resultant global financial meltdown. Most of the literature notes unequivocally that discrimination in the mortgage market has been, and remains, race-based and that it has damaged the African-American population disproportionately. This paper discusses the consequences of the subprime mortgage calamity and its negative impact on the Black community, women in general, and African-American women in particular. After controlling for individual, credit and housing characteristics, research shows that disparities in lending have persisted. Studies indicate that 63% of those given subprime mortgages qualified for prime mortgages. African-American females received the most high-cost loans and were over twice as likely to be given a subprime mortgage compared to White females. Moreover, African-American women were five times more likely to have received a subprime loan than similarly situated White males. Upper-income Black women were more often targeted for high-cost loans than lower-income women of color. As a result, the subprime mortgage crisis has precipitated an enormous loss of home equity and wealth among African-Americans that will affect generations to come.     

Diagnosing housing fever with an econometric thermometer

Housing fever is a popular term to describe an overheated housing market or housing price bubble. Like other financial asset bubbles, housing fever can inflict harm on the real economy, as indeed the U.S. housing bubble did in the period following 2006 leading up to the general financial crisis and great recession. One contribution that econometricians can make to minimize the harm created by a housing bubble is to provide a quantitative “thermometer” for diagnosing ongoing housing fever. Early diagnosis can enable prompt and effective policy action that reduces long-term damage to the real economy. This paper provides a selective review of the relevant literature on econometric methods for identifying housing bubbles together with some new methods of research and an empirical application. We first present a technical definition of a housing bubble that facilitates empirical work and discuss significant difficulties encountered in practical work and the solutions that have been proposed in the past literature. A major challenge in all econometric identification procedures is to assess prices in relation to fundamentals, which requires measurement of fundamentals. One solution to address this challenge is to estimate the fundamental component from an underlying structural relationship involving measurable variables. A second aim of the paper is to improve the estimation accuracy of fundamentals by means of an easy-to-implement reduced-form approach. Since many of the relevant variables that determine fundamentals are nonstationary and interdependent we use the endogenous instrumental variable based method (IVX) to estimate the reduced-form model to reduce the finite sample bias which arises from highly persistent regressors and endogeneity. The recursive evolving test proposed by Phillips, Shi, and Yu (PSY) is applied to the estimated nonfundamental component for the identification of speculative bubbles. The new bubble test developed here is referred to as PSY-IVX. An empirical application to the eight Australian capital city housing markets over the period 1999–2017 shows that bubble testing results are sensitive to different ways of controlling for fundamentals and highlights the importance of accurate estimation of these housing market fundamentals.     

Housing Fever in Australia 2020–23: Insights from an Econometric Thermometer

Australian housing markets experienced widespread and, in some cases, extraordinary growth in prices between 2020 and 2023. Using recently developed methodology that accounts for fundamental economic drivers, we assess the existence and degree of speculative behaviour, as well as the timing of exuberance and downturns in these markets. Our findings indicate that speculative behaviour was indeed present in six of the eight capital cities at some time over the period studied. The sequence of events in this nation-wide housing bubble began in the Brisbane market and concluded in Melbourne, Canberra, and Hobart following the interest rate rise implemented by the Reserve Bank of Australia in May 2022. As of March 2023, the housing markets in Sydney, Canberra and Hobart had broadly regained stability, while Melbourne's return to its normal state is more gradual. In addition, over-corrections against fundamentals are evident in the housing markets of Brisbane, Adelaide, Darwin and Perth.
