A peculiar archaeology: Searching for Mr Giffen's behaviour

Abstract

It has been claimed that references to ‘Giffen behaviour’ constituted a single research project, driven by attempts to establish whether an initial ‘conjecture’ by Alfred Marshall had empirical validity. There is no stable basis for that claim because Marshall's discussion was contradictory and Robert Giffen rejected a key assumption made by Marshall. By the mid-1920s, discussion of an upward-sloping demand curve attached no particular significance to a Marshallian story. The formulation of the Irish famine Giffen exemplar by P.A. Samuelson illustrates how Giffen behaviour was stabilised as the single possible exception to the law of demand in the 1960s.     

Community college economics instruction: Results from a National Science Foundation Project

The principal investigator of a National Science Foundation project, “Economics at Community Colleges,” surveyed community college economics faculty and organized workshops, webinars, and regional meetings to address community college faculty isolation from new ideas in economics and economics instruction. Survey results, combined with National Study of Postsecondary Faculty data, help fill a lacuna in information about community college faculty. A key finding is the reliance in community college economic instruction on part-time faculty, including many who do not hold a graduate degree in economics. The project's webinars reached the most community college faculty, while the workshops were most effective in improving economics instruction. Areas for future research are identified.     

Personalist Economics: Moral Convictions,Economic Realities,And Social Action

We examine the relationship between the administrative enforcement of environmental regulation, ethnic heterogeneity, and other community characteristics in New Jersey and New York. We find that the percentage of non-white population in a community is positively related with administrative penalties imposed on violators. However, penalties are lower in more ethnically diverse communities. This result may be due to the fact that these communities are less likely to coordinate to create solidarity across ethnic groups and demand stronger enforcement.     

Overcoming environmental scarcity,inequality and structural imbalance in the world economy

The world economy faces two major threats: increasing environmental degradation and a growing gap between rich and poor. The root cause is that natural resources—or natural capital—is underpriced, and hence overly exploited, whereas human capital—the skills embodied in the workforce—is insufficient to meet demand. This outcome has three important consequences. First, all sectors of an economy will use too much natural resources relative to skilled labor. Second, the skilled workers throughout the economy will have higher real incomes and thus will be better off. Third, wealth inequality will increase, as the income gap between skilled and unskilled workers widens. Addressing this structural imbalance requires correcting the two underlying distortions, which are the chronic under-pricing of natural capital and the under-investment in human capital. This must be accompanied by a new suite of policies to provide improved incentives for more balanced wealth creation.     

Problems of Emergency Arbitration

This paper explores ethical burdens facing the economics profession which are associated with epistemic features of economic practice. Economists exert power over those they purport to serve by virtue of epistemic asymmetry between themselves and others, i.e., the intellectual monopoly they enjoy over a vitally important body of knowledge. But they also face the problem of epistemic insufficiency, which implies that they may do substantial harm as they try to do good. The paper explores the ethical entailments of the epistemic features of economics, and argues that managing the ethical challenges requires a new field of inquiry, the field of professional economic ethics, and not just a code of conduct.     

Life beyond the Washington Consensus: An Introduction to Pro-poor Macroeconomic Policies

Abstract

This paper develops a rationale for the recession-induced inflation hypothesis. Within a conflicting claims framework we present a model in which both price leaders and organized workers set their nominal prices on the basis of a desired profit rate and a real wage target respectively. We argue that an absolute cost advantage in concentrated industries (for instance in fixed costs) may provide oligopolistic leaders sufficient margin to raise prices and restore a desired level of profitability during a recession. The resultizng unstable income distribution will set off an inflationary spiral if the firm's advantage in selling its output imparts an upward bias to the flexibility of input prices (specifically wages). Taking into consideration different scenarios for workers' bargaining power we present a simple simulation experiment to analyze the inflation and real wage paths of the economy after a negative output shock. When we endogenize output, we show that for a high degree of the bargaining power, output is likely to converge to a higher steady-state value.     

Capacity utilization and depreciation-in-use

In this paper, the effect capacity utilization has on the depreciation of capital goods is studied, starting from a quadratic approximation to a normalized short-run cost function. Expressions for the optimal rate of capacity utilization, the demands for labour and energy, and for investment are obtained. Investment is a function of past capital stock, expected future capital stock, expected future relative prices and expected future depreciation rates. Expectations are modelled via instruments. The model is tested using US total manufacturing quarterly data. Depreciation dependent upon usage is found to be both statistically and economically significant.     

Price and quality components of imports of food products into the UK

This paper analyses the principal factors responsible for the growth in the value of imports of the UK food sector, during the period 1985-90. On the basis of estimates of translog multilateral price indices it assesses the relative contribution of changes in the quality of imported products and factors other than quality to growth in import values of food products. The main conclusion is that growth in quality appears to be the principal reason for the growth in unit values of imports and the trade deficit incurred by the food manufacturing sector.
