Technology,productivity and economic analysis

A commonly held view is that innovation, deriving directly from expenditure on research and development, brings increased productivity, lower costs, increased profitability and growth, and that these relationships form a economically virtuous circle.However, this view is not supported either by the research results reported here or by other empirical findings. A richer and deeper framework of analysis than this “mythology” provides is required for management decision making in innovation and in this and the subsequent paper the author outlines the necessary features of such a framework.A model of a “network of productivity relationships” with six components is described which traces the effects of innovation, at any point in the network, on input productivities. The model points up the futility of single input measures of innovatory effects. This network is then combined with cost factors to show the effect on categories of unit costs and on total unit cost. Finally, profitability is related to the physical and cost factors to provide managerial control ratios which offer the relevent criteria by which innovation many be appraised.The history of innovation in the U.S. Basic Steel Industry is examined in the light of the model described above and hypotheses are proposed to identify possible productivity and cost effects of innovation with a view ot improving general predictive capability of the results of any given type of innovation.     

The impact of technological innovation—Concepts and measurement

Past studies of the economic effects of innovation have been based on inadequate conceptual foundations and their findings may therefore be invalid. In particular, too superficial and too narrow a view has been taken of the impact of innovation on inputs, outputs and production flows.The author argues the need for a deeper and more comprehensive framework for the analysis of innovation, showing resultant interaction among all the inputs and outputs of the system under study. For this, more effective measurements than have hitherto been available are required of output levels, inputs, productivity and unit costs. The paper then examines the deficiencies of currently used indices and indicates the conceptual requirements for more meaningful measurements of innovatory effects.     

A productivity study in a chemical plant

This paper describes a case study in the application of a productivity analysis model in a plant producing industrial gases. Although the process is a relatively simple one, several inputs (labour, electricity, capital and some materials) and several outputs (liquid and gaseous oxygen, gaseous nitrogen, argon and a hydrogen-nitrogen mixture) are involved. The case study demonstrates how measures of total input and total output can be applied and analyses the performance of the plant over a 15-month period in terms of a variety of managerial control ratios.     

Policy responses to external shocks in sub-Saharan African countries

The author analyzes the experience of sub-Saharan African countries with external shocks in the form of the deterioration of the terms of trade and the world recession between 1973 and 1978, with distinction made between low-income and middle-income countries. Adjustment to external shocks in low-income sub-Saharan African countries took largely the form of reductions in imports through lower rates of economic growth and lower income elasticity of import demand while these countries lost export market shares. Losses in export market shares were smaller in the middle-income countries and in the entire group, export performance was positively correlated with the rate of economic growth.     

Parents Beyond Borders: A Social Group Work Curriculum for Supporting Immigrant Parents and Building Solidarity

Parents Beyond Borders, a curriculum first implemented in 2008 as part of The Center for Family Life's ParentShip Program, encourages group members to create a shared narrative about their traumatic immigration experiences. The result is twofold. First, immigrant parents gain a more assertive and poignant voice to communicate with family and others in their lives when sharing their family's acculturation experience. Second, because social group work promotes recognition of collective trauma due to the community's experience of marginalization, it improves members' group self-concept and empowers them to take action and advocate for themselves.     

Prospects for trade in manufactured goods between industrial and developing countries, 1978–1990

This paper examines prospective changes in trade in manufactured goods between the industrial and the developing countries. Assuming the continuation of the policies followed by the industrial countries, it is projected that the manufactured imports of these countries from the developing countries would rise at an average annual rate of 12.5% between 1978 and 1980 while their manufactured exports would increase 9 7% a year. Nonetheless, the export surplus of the industrial countries in trade in manufactured goods would rise, contributing to the growth of industrial output. The expansion of their exports of manufactured goods would also contribute to economic growth in the developing countries, and both groups of countries would benefit from specialization according to comparative advantage.     

Identifying and controlling for program-level differences in comparative cost analysis: lessons from the economic evaluation of the National Breast and Cervical Cancer Early Detection Program

Performing economic evaluations of established health care programs is essential to identify and control for underlying program-level variations and to make valid comparisons. At a time when the need for such evaluations is growing, health care professionals have limited information on the methodological challenges of performing these evaluations. In this study, we used the National Breast and Cervical Cancer Early Detection Program to illustrate these potential underlying variations. We performed site visits to four grantees and collected activity-based cost data from nine additional representative programs. We identified five specific types of cost factors that should be considered when evaluating and comparing health care programs: clinical services, service mix, in-kind contributions, indirect costs, and year-to-year expenditures of specific activities. A key lesson is that case studies and pilot testing should be performed before initiating cost analysis to identify underlying variation and to test appropriate methods to adequately control for these differences.     

Community as text: using the community as a resource for learning in community schools

The community can serve as a resource to help students become more engaged in learning and strengthen connections between schools and community.     

A macro-micro approach to analyzing the determinants of price changes

This paper suggests an approach to analyzing the determinants of changes in industrial prices which provides a bridge between the broad macro perspectives of the Walrasian approach and the narrowly focussed micro approach of traditional demand and supply analysis. The analytical usefulness of the proposed approach is then explored through applications to several industrial price series. Finally, efforts are made to account for some of the interactions between product-specific short-term price adjustments and wider as well as longer-term price movements.
