What Happened to Kapp’s Theory of Social Costs? A Case of Metatheoretical Dispute and Dissent in Economics

In the early 1970s Wilfred Beckerman and K. William Kapp engaged in a serious dispute. Although it focused on social costs, the dispute raised issues about the very foundations of economics. The differences in approach to social costs that this dispute exposed were so deep-rooted as to preclude (or at least hinder) any possibility of constructive dialogue. This article argues that the subsequent ‘conspiracy of silence’ against Kapp should be understood in terms of Kapp’s very different conception of economics as a social science. This issue is relevant to a broader discussion about the boundaries of pluralism in economics—how these boundaries are drawn and the conditions for a constructive dialogue among economists and with other social scientists.     

Government spending, capital accumulation and the optimal policy rule: The role of public service capital

In this paper, we modify the Djajić [Djajić, S., 1987. “Government Spending and the Optimal Rates of Consumption and Capital Accumulation,” Canadian Journal of Economics 20, 544–554.] model in such a way that government consumption expenditure provides utility to households via the total stock of government services rather than the government consumption flow alone. By using such a framework, we show that the optimality condition for the public service capital stock is the marginal rate of substitution between public service capital and consumption that equals the intertemporal marginal rate of transformation between the two goods. In addition, we show that the relationship between private consumption and public service capital in a household's utility plays an important role in determining the transitional behavior of relevant variables. We also examine the second-best government consumption expenditure policy. By contrast, in the standard flow specification, e.g., Turnovsky and Brock [Turnovsky, S.J. and Brock, W.A., 1980. “Time Consistency and Optimal Government Policies in Perfect Foresight Equilibrium,” Journal of Public Economics 13, 183–212.], Ihori [Ihori, T., 1990. “Government Spending and Private Consumption,” Canadian Journal of Economics 23, 60–69.], and Turnovsky and Fisher [Turnovsky, S.J. and Fisher, W.H., 1995. “The Composition of Government Expenditure and its Consequences for Macroeconomic Performance,” Journal of Economic Dynamics and Control 19, 747–786.], the second-best government consumption expenditure is decided on the basis that the marginal utility of consumption is equal to the discounted sum of the marginal utility of the government's flow spending.     

Poetic Economics and Experiential Knowledge,or How the Economist K. William Kapp Was Inspired by the Poet Ernst Wiechert

In the first part of this article, I analyze the phenomenon of the “double truth” in economics, which suppresses experiential knowledge and leads to the destruction of the natural environment, community, and human civility. Subsequently, I explore the positive effects of opening economics to the creative, esthetic, and ethical potential of experiential knowledge, including works of art. In the second part of the article, I showcase the way the economist K. William Kapp was inspired by the renowned German novelist, poet, educator, intellectual, and concentration-camp survivor Ernst Wiechert. Wiechert was Kapp’s teacher in high school, the Hufgymnasium in Königsberg, during the Weimar Republic. I investigate the unpublished and unexplored Kapp-Wiechert correspondence, as well as analyze some (published and unpublished) foreign language essays written by Kapp and his wife Lore Kapp. This analysis reveals how Kapp’s economics drew lasting inspiration from Wiechert’s art philosophy, pedagogy, novels, and poetry. This is a case study of a poetic economics that is open to experiential knowledge, which makes it more humane, edifying, serene, and sensitive to the natural and social environment.     

The inherent dangers of using computable general equilibrium models as a single integrated modelling framework for sustainability impact assessment. A critical note on Böhringer and Löschel (2006)

The search for methods of assessment that best evaluate and integrate the trade-offs and interactions between the economic, environmental and social components of development has been receiving a new impetus due to the requirement that sustainability concerns be incorporated into the policy formulation process. A paper forthcoming in Ecological Economics [Böhringer, C., Löschel, A., in press. Computable general equilibrium models for sustainability impact assessment: status quo and prospects, Ecological Economics.] claims that Computable General Equilibrium (CGE) models may potentially represent the much needed “back-bone” tool to carry out reliable integrated quantitative Sustainability Impact Assessments (SIAs). While acknowledging the usefulness of CGE models for some dimensions of SIA, this commentary questions the legitimacy of employing this particular economic modelling tool as a single integrating modelling framework for a comprehensive evaluation of the multi-dimensional, dynamic and complex interactions between policy and sustainability. It discusses several inherent dangers associated with the advocated prospects for the CGE modelling approach to contribute to comprehensive and reliable sustainability impact assessments. The paper warns that this reductionist viewpoint may seriously infringe upon the basic values underpinning the SIA process, namely a transparent, heterogeneous, balanced, inter-disciplinary, consultative and participatory take to policy evaluation and building of the evidence-base.     

Social norms,cooperation and inequality

This paper analyzes the outcomes that can be supported by social norms in a society of infinitely lived and patient agents that are randomly matched in pairs every period to play a given game. I find that any mutually beneficial outcome can be supported by a self-enforcing social norm under both perfect information and a simple local information system. These Folk Theorem results explain not only how social norms can provide incentives that support cooperation in a community, providing support to the concepts of social capital and corporate culture, but also how they can support inequality and discrimination.I am grateful to David Levine for invaluable guidance and ideas. I also thank Anna Aizer, Hongbin Cai, Walter Cont, Ernesto Dal Bó, Jean-Laurent Rosenthal, Federico Weinschelbaun, William Zame, anonymous referees and seminar participants at Universidad de Buenos Aires, UCLA, Universidad T.

Green consumers and public policy: On socially contingent moral motivation

“Green” consumers appear to accept individual responsibility for the provision of public goods. The propensity to take such responsibility may depend on beliefs about others’ behavior, even for consumers motivated by internalized moral norms, not by social sanctions. This effect can produce multiple equilibria with either high or low demand for “green” products. Permanent increases in green consumption may be achieved by imposing temporary taxes or subsidies, or through advertising that influences beliefs about others’ behavior or about external effects. If a tax is interpreted as taking responsibility away from the individual, however, taxes can reduce the influence of moral motivation.     

新制度经济学能统一社会科学吗?

本文对科斯和诺思提出的新制度经济学能统一社会科学的命题进行了诠释.与其说新制度经济学统一社会科学,倒不如说它们之间是一种互动关系,他们相互需要.没有其他社会科学的支撑,新制度经济学的研究很难向纵深方面发展;社会科学借助新制度经济学的理论和方法可以大大地拓展研究领域,提高其解释力.这种互动将有利于社会科学(包括经济学)的繁荣与发展.     

Inequality persistence through vertical vs. horizontal coalitions

This paper aims to contribute to a better understanding of the observed high persistence of cross-country differences in inequality. It focuses on the interactions between inequality and the predominance of either horizontal coalitions (among individuals of similar economic status) or vertical ones (among individuals with different economic status). A model is proposed showing that the interactions between inequality and the type of coalition formed in a society can give rise to self-sustained social contracts where inequality persists. Key mechanisms of the model are illustrated using the transformation in inequality, redistribution and social relations in Modern England, as well as the “paternalist” system of the US South at the beginning of the XXth century.     

Growth and social security: the role of human capital

This paper studies the growth and efficiency effects of pay-as-you-go financed social security when human capital is the engine of growth. Employing a variant of the Lucas model [Lucas, R.E., 1988. On the mechanics of economic development. Journal of Monetary Economics 22, 3–42.] with overlapping generations, it is shown that a properly designed, unfunded social security system leads to higher output growth than a fully funded one. Furthermore, the economy with an unfunded social security is efficient, while the other one is not. These results stand in sharp contrast to those obtained in models where the reason for economic growth is physical capital accumulation.     

Which Regional Inequality? The Evolution of Rural–Urban and Inland–Coastal Inequality in China from 1983 to 1995

This paper develops a unified empirical framework for describing the relative contribution of rural–urban and inland–coastal inequality to overall regional inequality in China during the 1980's and 1990's. The framework assesses rural–urban and inland–coastal inequalities from the same data set, presents results for a sufficiently long time period to transcend short-term fluctuations, allows for differential price changes, and applies a consistent notion of the contribution to inequality using a decomposition analysis. While the contribution of rural–urban inequality is much higher than that of inland–coastal inequality in terms of levels, the trend is very different. The rural–urban contribution has not changed very much over time, but the inland–coastal contribution has increased by several fold. The paper ends by investigating the role of labor migration in this outcome. J. Comp. Econom., December 1999, 27(4), pp. 686–701.

Equilibria in systems of social interactions

In this paper, we establish existence and uniqueness results for equilibria in systems with an infinite number of agents and with local and global social interactions. We also examine the structure of the equilibrium distribution and derive a “Markov”property for the equilibrium distribution of a class of spatially homogeneous systems.     

Examining the global environmental impact of regional consumption activities — Part 2: Review of input-output models for the assessment of environmental impacts embodied in trade

This paper offers a detailed review of recently described single- and multi-region input-output models used to assess environmental impacts of internationally traded goods and services. It is the second part of a two-part contribution. In Part 1 [Turner, K., Lenzen, M., Wiedmann, T. and Barrett, J. in press. Examining the Global Environmental Impact of Regional Consumption Activities — Part 1: A Technical Note on Combining Input-Output and Ecological Footprint Analysis; Ecological Economics.] we describe how to enumerate the resource and pollution content of inter-regional and inter-national trade flows with the aim to illustrate an ideal accounting and modelling framework for the estimation of Ecological Footprints.A large number of such environment-economic models have been described but only in the last few years models have emerged that use a more sophisticated multi-region, multi-sector input-output framework. This has been made possible through improvements in data availability and quality as well as computability. We identify six major models that employ multi-sector, multi-region input-output analysis in order to calculate environmental impacts embodied in international trade. Results from the reviewed studies demonstrate that it is important to explicitly consider the production recipe, land and energy use as well as emissions in a multi-region, multi-sector and multi-directional trade model with global coverage and detailed sector disaggregation. Only then reliable figures for indicators of impacts embodied in trade, such as the Ecological Footprint, can be derived.     

The CO2 ‘trade balance’ between Scotland and the rest of the UK: Performing a multi-region environmental input–output analysis with limited data

In this paper we attempt an empirical application of the multi-region input–output (MRIO) method proposed by Turner, Lenzen, Wiedmann and Barrett [Turner, K., Lenzen, M., Wiedmann, T., Barrett, J., 2007. Examining the global environmental impact of regional consumption activities — part 1: a technical note on combining input–output and ecological footprint analysis. Ecological Economics 62 (1), 37–44] in a recent issue of this journal in order to enumerate the CO2 pollution content of interregional trade flows between Scotland and the rest of the UK (RUK). We extend the analysis to account for direct emissions generation by households, as final consumers, and to a social accounting matrix (SAM), where a more comprehensive account of incomes and expenditures is possible. While the existence of significant data problems mean that the quantitative results of this study should be regarded as provisional, the interregional economy-environment IO and SAM framework for Scotland and RUK allows an illustrative analysis of some very important issues in terms of the nature and significance of interregional environmental spillovers within the UK and the existence of a CO₂ ‘trade balance’ between Scotland and RUK.     

Conceptual Displacement: From the Natural to the Social

This paper distinguishes between epistemological naturalism, which it supports, and ontological naturalism, which it opposes. It sketches the emergence of anti-naturalist social theory among nineteenth-century African-American intellectuals and its refinement by twentieth-century feminists. These movements challenged ontological naturalism in the social sciences by substituting social constructionist concepts of race and gender for naturalist ones. Economics awaits a similar liberation. The paper identifies four naturalist concepts—atomism, determinism and biologically determined race and gender differences—as structuring mainstream economic theory. It concludes that ontological naturalism is inconsistent with the application of the epistemology of the natural sciences to the social sciences.     

Considering the effects of imprecision and uncertainty in ecological footprint estimation: An approach in a fuzzy environment

This paper demonstrates the development of the Ecological Footprint within a fuzzy environment. The approach taken provides a means to understand the impacts of imprecision and uncertainty in the input-output framework, which forms a cornerstone of many recently constructed Footprint estimates. The paper uses, as a basis, an example of Footprint construction presented in the paper of Bicknell et al. [Bicknell, K.B., Ball, R.J., Cullen, R., Bigsby, H.R., 1998. New methodology for the Ecological Footprint with an application to the New Zealand economy. Ecological Economics 27, 149-160]. The analysis considers levels of fuzziness surrounding the technical coefficients in the underlying input-output framework. The results presented fully exposit the effect of the defined analysis, including the presentation of; fuzzy sector Ecological Footprints and overall fuzzy Ecological Footprint. Accompanying these findings, the fuzzy versions of certain moments associated with these Footprints are also presented, namely possibilistic mean and variance. The findings contribute to the elucidation of the potential policy impacts afforded when acknowledging imprecision and uncertainty in the data used in estimating Ecological Footprints.     

The cost of labor adjustment: Inferences from the gap

This paper studies the aggregate implications of micro-level labor adjustment costs. Caballero and Engel [Caballero, R., Engel, E., 1993. Microeconomic adjustment hazards and aggregate dynamics. Quarterly Journal of Economics 108, 313–358] find a dependence of aggregate employment growth on the cross sectional distribution of “employment gaps.” This paper uses those results as moments in an indirect inference procedure to infer the underlying labor adjustment costs. We specify a dynamic optimization problem at the plant level, allowing for both convex and non-convex adjustment costs. Consistent with evidence at the micro level, our findings indicate that non-convex adjustment costs are necessary to match these aggregate moments.     

A re-examination of the technological catching-up hypothesis across OECD industries

This study re-examines the catching-up hypothesis at the industry level across the main OECD countries, using panel data econometric models involving technological gap indicators calculated with a nonparametric distance function suggested by Färe et al. [Färe, R.S., Grosskopf, M.N., Norris, M., Xhang, Z., 1994. Productivity growth, technical progress, and efficiency change in industrialized countries. American Economic Review 84, 66–83]. The results show that there is statistical evidence of a catching-up process at the industry level. Moreover, both tradables and nontradables sectors exhibit catching-up effects and technology adoption from abroad. This result complements the findings by Bernard and Jones [Bernard, A.B., Jones, C.I., 1996a. Comparing apples to oranges: productivity convergence and measurement across industries and countries. American Economic Review 86(5), 1216–1238., Bernard, A.B., Jones, C.I., 1996b. Productivity across industries and countries: Time series theory and evidence. Review Of Economics and Statistics 78, 135–146], Gouyette and Perelman [Gouyette, C., Perelman, S., 1997. Productivity convergence in OECD services industries. Structural Change and Economic Dynamics 8, 279–295] and Hansson and Henrekson [Hansson, P., Henrekson, M., 1997. Catching up, social capability, government size and economic growth, in V. Bergström, eds, Government and Growth, Oxford: Clarendon Press, 61–126] that there is no (or even a slow) catching-up effect in the manufacturing sector. Moreover, social capability indicators evaluated for each country show that “Non-European” and “Central European” tradables sectors have a rather similar degree of inefficiency while “North European” countries are less efficient for both tradables and non-tradables. Lastly, both the cross country and the cross sectors dispersions of inefficiency levels are smaller for tradables sectors than for non-tradables.     

Dynamics of agricultural groundwater extraction: Comment and correction

In a paper published in this journal, Hellegers et al. [Hellegers, P., D. Zilberman, E. van Ierland, 2001. Dynamics of agricultural groundwater extraction. Ecological Economics, 303-311] analysed a dynamic model of groundwater extraction in which they added the quality dimension of nitrate concentration to an intertemporal model of resource depletion. This contribution shows that the set-up of the model contains a serious mistake which affects the results of the paper and it corrects the results.
