Productivity Growth and Input Demand: The Effect of Learning by Doing in a Gold Mining Firm in a Developing Economy

This paper analyzes the effect of learning by doing (LBD) on the firm’s productivity growth and its input demand decisions. The results indicate that LBD is an important determinant of the firm’s productivity growth. The contribution of LBD to the firm’s productivity growth is about 5.6%. Another observation is that LBD has a decreasing effect on the firm’s cost of production – a finding which is consistent with the results of many studies. Also, an increase in LBD measured by cumulative production increases the firm’s demand for capital, and decreases the firm’s demand for labor. Lastly, LBD has a significant effect on the firm’s elasticity of scale. A fundamental message derived from the study is the confirmation that the firms should invest in more large capital equipment, embark on new processing techniques, and create an environment that is conducive to on-the-job learning.     

Stackelberg equilibrium with many leaders and followers. The case of zero fixed costs

I study a version of the Stackelberg game with many identical firms in which leaders and followers use a continuous cost function with no fixed cost. Using lattice theoretical methods I provide a set of conditions that guarantee that the game has an equilibrium in pure strategies. With convex costs the model shows the same properties as a quasi-competitive Cournot model. The same happens with concave costs, but only when the number of followers is small. When this number is large the leaders preempt entry. I study the comparative statics and the limit behavior of the equilibrium and I show how the main determinants of market structure interact. More competition between the leaders always displaces the followers. Instead, how a stronger threat of entry affects the equilibrium depends on the technology. With strictly convex costs it is the followers that eventually displace the leaders.

The impact of patient choice and waiting time on the demand for health care: results from the London Patient Choice project

In a number of countries where health care is publicly funded, policies to introduce greater patient choice are being implemented. In most cases patient choice is seen as an instrument to reduce waiting times for elective (non-emergency) hospital services. An important issue is whether facilitating greater patient choice will increase the demand for health care and thereby undermine the achievement of reduced waiting times. A large scale pilot of choice in the London metropolitan area permits a test of the hypothesis that choice will affect demand. This paper estimates a model of the demand for elective surgery using a panel of 150 English acute hospitals over the period 1995 to 2004 for three surgical specialties. It examines whether demand shifted following the introduction of the London Patient Choice Project in 2002. The results suggest that the choice project only shifted NHS inpatient demand in orthopaedics and that this shift was inwards.     

Expanded role of nursing in ambulatory managed care. Part II: Impact on outcomes of costs, quality, provider and patient satisfaction

This evaluation project used a triangulation of methods and data sources to link the expanded role nurse clinician (NC) to outcomes of costs, quality, and satisfaction in managed care. Results of patient surveys, case studies, cost-benefit analyses, interviews, focus groups, and HMO documents suggest that the impact of the role has benefit far beyond its costs. This article builds on an earlier article (Nursing Economic$, Vol. 17, No. 1). Part I reviewed literature on expanded role nursing in population management, and described the development of the NC role. In Part II, the NC expanded role is linked to organizational outcomes of costs, quality, and satisfaction. Results here could be used by managers and planners to provide rationale for implementing expanded nursing roles in managed care in order to improve ambulatory care processes, recruit and retain nurses, reduce costs, and increase patient and provider satisfaction.     

The changing role of consumers and suppliers in a food safety event: the 2006 foodborne illness outbreak linked to spinach

This article provides a means for testing whether buyers or sellers are responsible for a drop in sales following a market shock. We show that suppliers’ responses dominated the market reaction to the 2006 US Food and Drug Administration warning to avoid fresh spinach contaminated with potentially deadly bacteria Escherichia coli O157:H7. A modified Durbin-Wu-Hausman test for temporary price endogeneity is developed and used in a leafy green vegetable demand model. Test results indicate the price of bagged spinach was exogenous before the announcement but endogenous for approximately 12 weeks afterward. We show these results are consistent with the notion that suppliers temporarily limited the availability of spinach to consumers. Instead of consumers choosing the quantity purchased given exogenous prices, it was suppliers who limited the quantity marketed and consumers’ choices established the market price.     

The impact of nurse staffing on hospital costs and patient length of stay: a systematic review

Research examining the relationships between nurse staffing, hospital costs, and length of stay is varied using a range of methods and definitions. This lack of coherence in definitions and measurement tools for cost and length of stay makes it difficult to conclude with certainty the results of nurse staffing on hospital cost and length of stay. However, the evidence reflected that significant reductions in cost and length of stay may be possible with higher ratios of nursing personnel in hospital settings. Sufficient numbers of RNs may prevent patient adverse events that cause patients to stay longer than necessary. Patient costs were also reduced with greater RN staffing as RNs have higher knowledge and skill levels to provide more effective nursing care as well as reduce patient resource consumption. Hospital administrators are encouraged to use higher ratios of RNs to non-licensed personnel to achieve their objectives of quality patient outcomes and cost containment.

The political economy of public health expenditure and wait times in a public‐private mixed health care system

Abstract This paper investigates the determinants of public health expenditure in a public‐private mixed health care system, where a longer wait time for public care is the major difference between public and private sectors. Voter preferences for health care vary according to their age and by income, and public policy choices are part of a multi‐dimensional, competitive political equilibrium. We show how equilibrium public health expenditure and wait times depend on demographics and explain why they are independent of the distributions of income and political influence. We also show that population aging may not always lead to more public health expenditure.     

The relationship of the hospital-acquired injurious fall rates with the quality profile of a hospital's care delivery and nursing staff patterns

Fall occurrence during hospital stays is a well-recognized nursing-sensitive outcome indicator. This study was intended to determine the unique contributions of three inpatient satisfaction measures on the hospital-acquired injurious fall rates. Study results demonstrated the higher the inpatient satisfaction levels with the quietness of hospital environment, the lower the injurious fall rates. The physical environment (quietness) of the acute inpatient care settings was a significant and meaningful determinant of the prevalence of injurious falls. Additionally, more total nursing personnel FTEs per 1,000 discharges and a higher percentage of RN FTEs by total nursing personnel FTEs would not result in better patient outcomes.     

The future of the working classes: a comparison between J.S. Mill and A. Marshall

Abstract

Both J. S. Mill and A. Marshall had a lifelong interest in the living conditions of the working classes and theorized the possibility of a new age, characterized by a widespread mental and moral cultivation. This paper compares the precise arguments put forward by them in the period ranging from Mill's to Marshall's Principles, against the background of the evidence of social and human progress at their times. It is argued that, at different stages and with different specific arguments, their predictions relied on self-reinforcing mechanisms, in which a better life was the cause, no less than the effect, of progress. In order to make similarities and differences more transparent from a logical point of view, two simple mathematical formulations are proposed.     

The relative efficiency of public and private firms in a regulated environment: The case of U.S. electric utilities

The relative efficiency of privately-owned and publicly-owned electric utilities is investigated using theoretical and econometric models that allow for the effects of both ownership type and regulation. The estimation results indicate that the two types of firms are equally cost inefficient in the United States. The average effect of inefficiency is to increase the cost of production by 2.4 percent. Holding output constant, inefficiency increases the average quantities demanded of capital and labor and decreases the average quantity demanded of fuel.
