Welfare Effect of Mergers and Multilateral Trade Liberalization

In a two‐country model where firms behave à la Cournot, we show that trade liberalization increases (decreases) the social desirability of those mergers that generate sufficiently large (small) reductions in marginal cost. There exists a range of intermediate levels of marginal cost savings such that marginal tariff reductions increase (decrease) the desirability of merger at sufficiently low (high) tariff levels. Moreover, in the neighborhood of free trade, we show that if trade liberalization increases the profitability of a merger, it necessarily also increases its desirability.     

Incentives and targets in hospital care: Evidence from a natural experiment

Performance targets are commonly used in the public sector, despite their well known problems when organisations have multiple objectives and performance is difficult to measure. It is possible that such targets may work where there is considerable consensus that performance needs to be improved. We investigate this possibility by examining the response of the English National Health Service to high profile waiting time targets. We exploit a natural policy experiment between two countries of the UK (England and Scotland) to establish the global effectiveness of the targets. We then use a within-England hospital analysis to confirm that responses vary by treatment intensity and to control for differences in resources which may accompany targets. We find that targets met their goals of reducing waiting times without diverting activity from other less well monitored aspects of health care and without decreasing patient health on exit from hospital.     

A Cross Country Comparison of Child Nutrition and Investigation of its Demographic Determinants

This study pools data on child anthropometrics and on their determinants from Pakistan, Peru, Jamaica, Russia and South Africa. It, then, estimates regression equations of child height and weight, measured by the Z-scores, on both combined country data and, separately, for each country. Moreover, the study estimates the child height and weight equations, separately, for young (0–36 months) and older children (37–72 months) and provides evidence on the impact of household assets and of a household’s access to basic amenities on the health of its children. The child health in the five countries chosen, which are culturally, economically, politically and geographically, quite diverse, are compared. The paper finds that the hard core cases of child malnutrition are not necessarily related to poverty or inequality. Female education plays an effective role in improving child health, with its beneficial effects considerably enhanced in households with access to public information through the radio or the TV.

     

INTANGIBLE CAPITAL AND U.S. ECONOMIC GROWTH

Published macroeconomic data traditionally exclude most intangible investment from measured GDP. This situation is beginning to change, but our estimates suggest that as much as $800 billion is still excluded from U.S. published data (as of 2003), and that this leads to the exclusion of more than $3 trillion of business intangible capital stock. To assess the importance of this omission, we add intangible capital to the standard sources-of-growth framework used by the BLS, and find that the inclusion of our list of intangible assets makes a significant difference in the observed patterns of U.S. economic growth. The rate of change of output per worker increases more rapidly when intangibles are counted as capital, and capital deepening becomes the unambiguously dominant source of growth in labor productivity. The role of multifactor productivity is correspondingly diminished, and labor's income share is found to have decreased significantly over the last 50 years.     

Fiscal policies, environmental pollution and economic growth

This paper develops a model of endogenous economic growth with special consideration to the role of productive public expenditure and environmental pollution; and analyses the properties of optimal fiscal policy in the steady state growth equilibrium. We consider the level of consumption as the source of pollution. Government allocates its tax revenue between pollution abatement expenditure and productive public expenditure. Optimum ratio of productive public expenditure to national income is equal to the competitive output share of the public input, when productive public expenditure is depicted as tax revenue minus abatement expenditure. However, the proportional income tax rate exceeds the competitive output share of the public input. There is no conflict between the social welfare maximizing solution and the growth rate maximizing solution in the steady state growth equilibrium. The unique steady state growth equilibrium appears to be a saddle-point when the growth rate is above a critical level and the steady state equilibrium growth rate in the market economy is not necessarily lower than the socially efficient growth rate.     

Integration of the Kano and QFD model in health food development: using black beans as examples

This study applied the Kano two-dimensional quality model and quality function deployment (QFD) to develop the black bean’s reputation as a health food and identify quality attributes of consumers’ needs in order to effectively control the attributes. This study first conducted a literature review and summarized the product’s quality attributes and then carried out expert interviews to determine health food quality attributes and consumer need quality attributes. A questionnaire survey was conducted to discuss which quality attributes of black beans consumers perceived to be important when they were presented as a health food and classify their answers using the quality attributes in the Kano model in order to effectively control consumers’ needs. Consumers’ demand for quality attributes was transformed into a technique of product quality development. In a matrix of the two constructs, quality classification of health food in the Kano model and order of consumers’ satisfaction with eating types of health food products, quality factors were transformed into technical specifications of product development for QFD and the construction of the first-stage of the House of Quality matrix. The results serve as references for companies to effectively distribute resources and establish strategies of product development, enhance product quality and consumer satisfaction, reduce product development time, and increase the success rate of products in the market. The results contribute to the health food enterprises are not only can make profit of product but also meet customers’ need.     

Memoryless Reigns of the “Sons of Heaven”

Human lifetimes have increasing failure rates; as people age (beyond early childhood) they are more likely to die. Viewing the succession of Chinese Emperors as a statistical ensemble we show that, unlike lifetimes, their reigns ceased at a constant rate for over two millennia, unaffected by elapsed time. In fact reign lengths of the “Sons of Heaven”, as the Chinese Emperors were known, followed a memoryless exponential distribution with a 10-year half-life. Becoming emperor not only influenced the duration of remaining life, but length of rule was independent of age at ascent. We propose an explanation for the observed exponentiality using asymptotic results from the theory of stationary stochastic processes.     

The State of Public Sector Unionism: Challenges and Opportunities

The face of unionism in the United States is becoming increasingly public sector. On the surface, public sector unionism appears as a bright spot for labor. A more careful examination of the data, however, reveals that such unionism is at a standstill. Absolute growth has been insufficient to offset losses in private industry, and it is largely tied to increases in public employment. Public employee unions face numerous serious challenges, and questions have been raised in the federal service about the very legitimacy of union representation. Future scenarios suggest that public sector unionism as a whole will likely remain in a more or less stagnant position.     

Critical Political Economy and Material Transformation

The starting point for this paper is that critical political economy needs to take up the challenge that originates in Marx's seminal contributions of conceptualising the economy as both processes of value creation and processes of material transformations. This is because, inter alia, the successful production of commodities requires knowledge of their constituent materials and their potential transformations and the ways in which these can be managed through the production process to allow the creation of surplus value and profits. Using the steel and automobile industries as an example, I show how a wide range of materials can be produced with a variety of desirable properties through careful control of the production process. Sophisticated management of the production process depends upon the knowledge of the properties of the materials and of the ways in which these can be combined and transformed to give types of steels with particular desired combination of properties. Capitalist interests have increasingly shaped the processes of R&D through which knowledge about the materials, their properties and their transformations has been developed and deployed to produce profits via producing steel and – inter alia – automobiles.
