Convergence of consumption patterns during macroeconomic transition: A model of demand in Ireland and the OECD

This study uses country-level panel data on consumption in Ireland and seven other OECD countries to examine the evolution of Irish consumption patterns as Ireland underwent rapid macroeconomic growth. Consumption levels obviously increased due to substantially higher incomes, but it is less clear how the shares of different types of goods purchased have changed or whether Ireland's consumption mix has converged with that of other high-income countries. Rankings based on a simple distance measure of consumption similarity suggest that Ireland moved from a “low-income” pattern similar to Portugal or Greece to a “high-income” pattern like that of Canada between 1995 and 2003. Using static and dynamic Almost Ideal Demand System models, we first estimate long- and short-run Irish price and income elasticities for nine categories of commodities between 1976 and 2003. These results provide evidence of substantial habit formation in aggregate consumption. We then estimate a long-run cross-country model covering six aggregate commodity groups between 1975 and 2003. The analysis shows that Ireland's demand parameters remain more similar to those of Greece than to higher-income OECD countries in the sample. Although Ireland has overtaken most other OECD countries in per capita income, it is still converging to a higher-income consumption pattern. We foresee further convergence of Irish expenditure patterns towards a pattern typical of high-income countries.     

Awareness and perceptions of the Johnson & Johnson Campaign for Nursing's Future: views from nursing students, RNs, and CNOs

Johnson & Johnson launched the Campaign in February 2002. Data from surveys of nursing students, RNs, and CNOs reflect a high level of awareness of several key elements of the Campaign--advertisements, recruitment materials, the discovernursing.com Web site, and regional "Promise of Nursing" fundraising events. The J & J Campaign for Nursing's Future represents the largest involvement of the private corporate sector, and through this initiative we are learning new and innovative ways to examine the challenges confronting the nursing workforce and develop actions to help resolve them.     

Healthcare resource utilization and costs in patients with newly diagnosed acute myeloid leukemia

Abstract

Aim: Acute myeloid leukemia (AML) is associated with high disease burden. This analysis estimated HRU and costs among newly diagnosed AML patients in a US commercially insured population.

Materials and methods: This was a retrospective observational study using the IMS Health PharMetrics Plus and Hospital Charge Detail Master databases. Patients included adults who were newly diagnosed with AML between January 2007 and June 2016 (“study period”). Patients with <12 months of continuous enrollment prior to the index date were excluded, as were those whose first diagnosis was AML in remission/relapse, those diagnosed with acute promyelocytic leukemia, those on Medicare supplemental insurance, or those with a diagnosis of AML in remission/relapse without evidence of treatment during the study period. Patients were stratified by receipt of AML treatment (chemotherapy/hematopoietic cell transplantation [HCT]), and their follow-up was partitioned into initial, remission, and relapsed health states. Mean HRU and costs were tallied by treatment and, for treated patients, by health state and time since entry into health state (≤6 vs >6 months).

Results: A total of 9,455 patients met study criteria, including 6,415 (68%) treated and 3,040 (32%) untreated patients, with mean follow-up of 18.3 and 16.4 months, respectively. Mean age was 55 years in treated patients and 60 years in untreated patients. Mean total costs per patient were $386,077 in treated patients and $79,382 in untreated patients. For treated patients, 60% of total costs ($231,867 per patient) were incurred during the initial health state, representing time without remission/relapse. Mean monthly total healthcare costs were $21,055 and $4,854 among treated and untreated patients, respectively.

Limitations and conclusions: HRU and costs of managing AML patients are substantial. In treated patients, the majority of costs were incurred during the initial treatment period, without claims indicating remission/relapse.     

Comparing the costs and benefits of diversification by regulated firms

Previous work on the diversification of regulated firms has focused exclusively on either the costs of cross-subsidy or on the welfare gains resulting from economies of scope. Using theory and numerical simulations, we identify conditions under which gains from economies of scope and increased competition tend to outweigh the costs of cross-subsidization. We use a perfect competition model of the unregulated market to examine tradeoffs under economies of scope. Effects of increased competition are assessed using Cournot models with linear and constant elasticity demands. Diversification tradeoffs depend upon magnitudes of variables that regulators should be able to estimate or otherwise judge.     

Implementing Electricity Restructuring

Electricity is one of the last U.S.industries in which competition is replacingregulation. We briefly review the technologyfor producing and delivering power, the historyof electricity policy, and recent state andinternational experience. We then outline themajor questions facing policymakers as theydecide whether, when, and how to implementrestructuring. We conclude with some thoughtson the California electricity crisis and otherpolitical controversies. Although theCalifornia experience has come to define whatit means for electricity markets to fail, mostof the problems it raised are among those weknow how to solve or prevent. The stillunresolved make-or-break issue remains whetherthe cooperation necessary to maintainreliability is compatible with the degree ofcompetition necessary to bring about greaterefficiency and lower prices.     

What’s powering wind? The effect of the U.S. state renewable energy policies on wind capacity (1994–2012)

As of 2012, 29 states had enacted a Renewable Portfolio Standard (RPS), while 37 states had at least one utility offering Green Power Purchasing (GPP) to their customers. The goal of both policies is to promote the adoption of clean, renewable energy. This article examines the influence of these polices on wind capacity across the United States from 1994–2012, a period of significant expansion of the wind generation market. The analysis focuses on wind because as compared with other modern renewable energy sources, wind is the only renewable energy source to make significant inroads into the U.S. electricity generation market. My findings indicate that while there have been significant increases in commercial scale wind generation capacity, neither RPS nor GPP programmes had a significant influence on within state wind capacity additions.     

Linkages between property asset returns and interest rates: evidence for the UK

This paper considers the effect of short- and long-term interest rates, and interest rate spreads upon real estate index returns in the UK. Using Johansen's vector autoregressive framework, it is found that the real estate index cointegrates with the term spread, but not with the short or long rates themselves. Granger causality tests indicate that movements in short term interest rates and the spread cause movements in the returns series. However, decomposition of the forecast error variances from VAR models indicate that changes in these variables can only explain a small proportion of the overall variability of the returns, and that the effect has fully worked through after two months. The results suggest that these financial variables could potentially be used as leading indicators for real estate markets, with corresponding implications for return predictability.     

Relative wages and trade-induced changes in technology

We develop a model where trade liberalization leads to skill-biased technological change, which in turn raises the relative return to skilled labor. When firms get access to a larger market, the relative profitability of different technologies changes in favor of the more skill-intensive technology. As the composition of firms changes to one with predominantly skill-intensive firms, the relative demand for skilled labor increases. This way, we establish a link between trade, technology and relative returns to skilled and unskilled labor.
