Does Libertarian Paternalism Reconcile Merit Goods Theory with Mainstream Economics?

In the wake of Musgrave's move to question the absolute hegemony of individual preferences for normative economics in the 1950's by propounding the existence of merit goods, a recent book by Thaler and Sunstein is now making a similar claim under the label of ‘libertarian paternalism’. This paper tackles the question of why the framework of libertarian paternalism has received a so much more friendly reception among economists than the theory of merit goods. The main reason is a better foundation, not only for the conditions under which paternalism may be justified but also for the tools that should be applied, utilizing transaction cost theory.     

Is Pragmatism Good for Anything? Towards a Theory of Impractical Economics

This article discusses the relationship between classical pragmatism, political economy and economic policy. Classical pragmatism is contrasted with vulgar meanings and uses of the term pragmatism. Classical pragmatism aims at a deep, substantive theoretical understanding of real-world economic systems and supports application of well-warranted claims to knowledge to improve the human condition. The article reviews the contributions of the founder of pragmatism, Charles Sanders Peirce, to the areas of ontology and epistemology as well as their further development by contemporary classical pragmatist philosopher Susan Haack. Hilary Putnam’s argument that we can have ethics without ontology and objectivity without objects is then critiqued. We need ethics based on an ontology that is rooted in actual human experience; this provides better guidance for evaluating policy proposals. The paper concludes by discussing the affinity of classical pragmatism with different approaches to political economy and policy.

Is Gerard Debreu a Deductivist? Commentary on Tony Lawson's Economics and Reality

Tony Lawson has argued that the methodology of neoclassical economics is deductivist: in constructing their formal models, economists hope to be able to provide explanations based on laws, as described by the deductive-nomological model of explanation. This article argues in contrast that neoclassical economics cannot be understood as following just one methodology. It is argued that neoclassicism exhibits two methodologies, one “official” and one tacit. The former is empiricist, and corresponds to the practice that has been described by Lawson. The latter, which can be called “hypothetico-deductive rationalism”, amounts to the position that knowledge of the world can be obtained without any empirical verification of one's assumptions, simply by exploring the implications of the assumptions one makes.

What Is Supply-and-Demand? The Marshallian Cross Versus Classical Economics

This study argues that the supply-and-demand apparatus of the ‘Marshallian cross’ is an unsatisfactory representation of actual supply and demand forces, which are better characterized in the manner of the classical economists. Most particularly the rising supply function but also the conventional demand function, are shown to have no compelling general theoretical justification. There is no plausible basis for a presumption in favour of the former—other than the marginal productivity theory of factor pricing, which is itself unsatisfactory. Multiple reasons are suggested for the rise of the apparatus of supply-and-demand functions, notwithstanding its intrinsic implausibility. The classical conception of supply-and-demand is restated and reaffirmed.     

Is smoking a fiscal good?

Even though smokers incur higher health expenditures than nonsmokers of the same age, smokers have significantly higher mortality rates, so the expected lifetime health expenditure for a smoker is actually lower than for a nonsmoker. Because of this fact, some politicians and policy-makers have argued that society might actually be better off promoting smoking rather than discouraging it. We consider this argument in a general-equilibrium model where health expenditures are paid for by a single-payer health-care system financed by taxes. Because the percentage increase in the tax base is larger than the percentage increase in health-care expenditures, the elimination of smoking actually decreases the budget-balancing health-care tax rate.     

Is Economics Responding to Critique? What do the UK 2015 QAA Subject Benchmarks Indicate?

Abstract

The Quality Assurance Agency for Higher Education provides subject benchmarks which inform but do not determine the content of university and college academic programmes in the United Kingdom. These are revised every few years and have recently been completed in economics for the first time since the global financial crisis. Given the extensive criticism of mainstream economics since the crisis, one might anticipate the benchmark revisions to be extensive. However, this has not been the case. This article explores why this is so. The analysis may also be considered of broader significance because the conditions under which the review has occurred involve general processes that will be familiar, albeit with local variation, to heterodox economists elsewhere. In the conclusion, a more fundamental reconstruction of the benchmarks is provided. These will also be of interest as general orienting statements for a different kind of economics.     

Does Environmental Economics Produce Aeroplanes Without Engines? On the Need for an Environmental Social Science

In this paper we first critically review conventional environmental economics. We conclude that the standard theory offers too narrow a perspective for many real world problems and that many theories are not empirically tested. Consequently, environmental economics is at risk of producing aeroplanes without engines. Next, we welcome and discuss some recent trends, particularly the rapid developments of behavioural and new institutional economics as well as the increased interest in empirical analysis. Yet, we conclude that more ‘logical duels’ between competing theories, more interaction between theory and empirics, and more integration between the social sciences are needed to achieve a better understanding of real world environmental problems and the development of adequate policy handles. Finally, we present an outline of steps towards the development of an environmental social science and briefly present the papers that make up this special issue as important building stones of such a discipline.     

Is there a self-enforcing monetary constitution?

A self-enforcing monetary constitution has rules that agents acting within the system will uphold even in the presence of deviations from ideal knowledge and complete benevolence. It thus does not require external enforcement. What would such a constitution look like? I show that two regimes—a version of nominal gross domestic product targeting that relies on market implementation of monetary policy, and free banking—meet these requirements for self-enforcing monetary constitutions. The analysis draws insights from political economy, and from constitutional political economy in particular.     

Is political popularity a random walk?

This paper tets for nonstationarity in the political popularity of UK parties and governments within the context of an economic model which predicts that party support is an ARIMA (0, 1, 1) process. The hypothesis is rejected for the government's popularity but the results for individual party support are less clear out.     

Too Much of a Good Thing? The Economics of Investment in R&D

Research and development is a key determinant of long-run productivity and welfare. A central issue is whether a decentralized economy undertakes too little or too much R&D. We develop an endogenous growth model that incorporates parametrically four important distortions to R&D: the surplus appropriability problem, knowledge spillovers, creative destruction, and duplication externalities. Calibrating the model, we find that the decentralized economy typically underinvests in R&D relative to what is socially optimal. The only exceptions to this conclusion occur when the duplication externality is strong and the equilibrium real interest rate is simultaneously high.     

Design of Stated Preference Surveys: Is There More to Learn from Behavioral Economics?

We discuss the design of stated preference (SP) surveys in light of findings in behavioral economics such as context dependence of preferences, learning, and differences between revealed and normative preferences. More specifically, we discuss four different areas: (1) revealed and normative preferences, (2) learning and constructed preferences, (3) context dependence, and (4) hypothetical bias. We argue that SP methods would benefit from adapting to some of the findings in behavioral economics, but also that behavioral economics may gain insights from studying SP methods.
