Feminist Ecological Economics and Sustainability

Synopsis New developments in feminist ecological economics and ecofeminist economics are contributing to the search for theories and policy approaches to move economies toward sustainability. This paper summarizes work by ecofeminists and feminist ecological economists which is relevant to the sustainability challenge and its implications for the discipline of economics. Both democracy and lower material throughputs are generally seen as basic principles of economic sustainability. Feminist theorists and feminist ecological economists offer many important insights into the conundrum of how to make a democratic and equity-enhancing transition to an economy based on less material throughput. These flow from feminist research on unpaid work and caring labor, provisioning, development, valuation, social reproduction, non-monetized exchange relationships, local economies, redistribution, citizenship, equity-enhancing political institutions, and labor time, as well as creative modeling approaches and activism-based theorizing.      

Clinic visit and waiting: patient education and satisfaction

Teaching should be part of every patient's health care. Even though this study did not show that teaching improves patient satisfaction with the clinic visit, it did indicate that subjects who were taught by the nurse were more satisfied with the education received during that visit.$     

THE DISTRIBUTION OF PUBLIC EXPENDITURE AMONG HOUSEHOLDS IN THE UNITED STATES*

This paper presents an analysis of the distributive impact of government expenditures in the United States. The analysis uses a household-level microdata file drawn from the 1970 U.S. Census of Population, with additional income and tax variables drawn from the Internal Revenue Service 1969—70 Tax File. The results are presented at both federal and local levels and include analyses of the distribution of individual benefits, as well as of overall taxes and net benefits. Since a microdata file was used, distributional effects are examined with respect not only to the “traditional” variables of income class and household size, but also with regard to the number of earners in the household and the sex and race of the household head. In a further paper in a subsequent issue of this review we will present the results of a similar analysis for the United Kingdom, and compare the results for the two countries.     

Do overweight and obesity prevalence rates converge in Europe?

We exploit recently published data to evaluate the long-run evolution of overweight and obesity rates among European economies between 1975 and 2016. We find that overweight rates for both females and males converge in Europe. In particular, the convergence is driven by the nations in the EU. This fact is consistent with food patterns as well as trade, agricultural, and health policies that are common among EU members. Across our model specifications, the steady-state average overweight rate ranges between 60% and 77% for European female individuals and lies above 82% for their male counterparts. Confidence intervals suggest that such gender differences are statistically significant. In the EU, the point estimates of these rates are 62% and 91%, respectively. Obesity prevalence in Europe would reach long-term rates of 39% and 45% for females and males respectively, whereas these rates would be similar in the EU (approximately 28%).     

FACTORS IN CANADA-UNITED STATES REAL INCOME DIFFERENCES

This paper is a part of a larger study of economic growth in Canada, following the methods developed by Edward Denison in his book The Sources of Economic Growth in the United States and the publication Why Growth Rates Differ. The new material in this paper relates to Canada and the Canadian/U.S. comparison, while the material on Northwest Europe is drawn from the Brookings study. The present paper sets out the results to date on the differences in real output per employed person between Canada and the United States for one year, 1960. At this stage in our research the results indicate that the level of real output per employed person in Canada was about 20 per cent lower than in the United States in that year. On the basis of historical output data, it would appear that this margin of difference in Canadian/U.S. product levels has persisted throughout the present century. The central part of this paper examines the significance of differences in factor inputs in Canada and the United States and their contribution to the difference in income. The level of inputs per employed person in Canada accounts for only about 2 percentage points of the income difference between Canada and the United States. These results indicate that the overwhelming part of the difference in output per employed person between the two countries reflects the differences in output in relation to total factor inputs, rather than the magnitude of other factor inputs used in combination with labour. This result is consistent with earlier studies by Denison and others which have indicated the crucial importance of output in relation to total factor inputs, both in output growth over time and intercountry comparisons of output level. The body of the paper can give only brief attention to the numerous conceptual and statistical questions that arise in such a wide-ranging study, and the authors do not pretend to have tackled, let alone resolved, all of the wide range of problems related to this study. Nor do they claim any high degree of precision for the results, especially in the light of the statistical limitations of the basic data.     

Breakthrough thinking from inside the box

Companies often begin their search for great ideas either by encouraging wild, outside-the-box thinking or by conducting quantitative analysis of existing market and financial data and customer opinions. Those approaches can produce middling ideas at best, say Coyne, founder of an executive-counseling firm in Atlanta, and Clifford and Dye, strategy experts at McKinsey. The problem with the first method is that few people are very good at unstructured, abstract brainstorming. The problems with the second are that databases are usually compiled to describe current--not future--offerings, and customers rarely can tell you whether they need or want a product if they've never seen it. The secret to getting your organization to regularly generate lots of good ideas, and occasionally some great ones, is deceptively simple: First, create new boxes for people to think within so that they don't get lost in the cosmos and they have a basis for offering ideas and knowing whether they're making progress in the brainstorming session. Second, redesign ideation processes to remove obstacles that interfere with the flow of ideas--such as most people's aversion to speaking in groups larger than ten. This article offers a tested approach that poses concrete questions. For example, what do Rollerblades, H?agen-Dazs ice cream, and Spider-Man movies have in common? The answer: Each is something that adults loved as children and that was reproduced in an expensive form for grown-ups. Asking brainstorming participants to ponder how their childhood passions could be recast as adult offerings might generate some fabulous ideas for new products or services.     

Sanac Inc.: From ABC to time-driven ABC (TDABC) – An instructional case

This case deals with the decision of Sanac Inc., a Belgian wholesale company, on whether to proceed with the implementation of an activity-based costing (ABC) system or switch to time-driven activity-based costing (TDABC). As a business consultant, you are hired to decide about the appropriate costing method. Your task is to decide which system the company should implement, given the desire of the president of the company to calculate profitability at the order and the customer level.     

The Model of a Gender-Segregated Low-Income Economy Reconsidered: Evidence from Uganda

This paper examines Darity's model of gender-segregated low-income agrarian society in light of evidence from Uganda. It identifies three important features of the interactions between men and women which are likely to have economic effects but which are subsumed within Darity's schematic presentation. It suggests a reformulation of the Darity model in terms of a bargaining framework. This facilitates greater insights into gendered economic processes that otherwise are ignored, and investigation of a wider range of macro outcomes.     

The stylized facts about the behavior of manufacturers' inventories and backorders over the business cycle: 1959–1980

Recent theoretical work has highlighted the role of inventories in propagating business cycles. This paper attempts to provide an empirical foundation for current and future research on the role inventories play in business cycles. The evidence presented here indicates that inventories and backorders are major variables in predicting output fluctuations. Further, the evidence is that disaggregating inventories by stage-of-fabrication is important in predicting output. In concert with previous findings, our results suggest that disaggregated inventories ought to be a component of models of the business cycle.
