Mind and Economy: Methodological Problems of Neuroeconomics

The Philosophy and Neuroscience Movement

Abstract: A movement dedicated to applying neuroscience to traditional philosophical problems and using philosophical methods to illuminate issues in neuroscience began about twenty-five years ago. Results in neuroscience have affected how we see traditional areas of philosophical concern such as perception, belief-formation, and consciousness. There is an interesting interaction between some of the distinctive features of neuroscience and important general issues in the philosophy of science. And recent neuroscience has thrown up a few conceptual issues that philosophers are perhaps best trained to deal with. After sketching the history of the movement, we explore the relationships between neuroscience and philosophy and introduce some of the specific issues that have arisen.

Michael Pauen
Neuroökonomie – Grundlagen und Grenzen

Abstract: According to a widespread view, neuroscientific basic research tells us more about the essence of the mind than psychology and may, in the long run, even replace those higher level approaches. Contrary to this view, it is demonstrated that many features can only be observed and explained on a certain level of complexity. This is particularly obvious in the case of neuromarketing and neuroeconomics. In both cases, neuroscientific methods depend on behavioral paradigms. Still, neuroscientific research in these fields may enhance our understanding of the underlying neural mechanisms. In addition, neuroeconomics provide excellent conditions for the study of human decision making.

The Brain Is Not Enough. Potentials and Limits in Integrating Neuroscience and Pedagogy

Abstract: The desire for founding educational reform on a sound empirical basis has coincided with a period of impressive progress in the field of neuroscience and wide public interest in its findings, leading to an ongoing debate about the potential of neuroscience to inform education reform. But is neuroscience really suited to provide specific instructions for improving learning conditions at school? This paper explores the educational implications of neuroscience.

Neuroeconomics Studies

Abstract: Neuroeconomics has the potential to fundamentally change the way economics is done. This article identifies the ways in which this will occur, pitfalls of this approach, and areas where progress has already been made. The value of neuroeconomics studies for social policy lies in the quality, replicability, and relevance of the research produced. While most economists will not contribute to the neuroeconomics literature, we contend that most economists should be reading these studies.

Neuroeconomics and the Logic of Behavior

Abstract: Recent neuroeconomic studies challenge the conventional economic logic of behavior. After an introduction to some starting points of brain research in 'classical' economics we discuss the final and contingent causes of rational and irrational behavior in neuroeconomics and standard economics and present the concept of expanded rationality models (ERM) which imports neuroeconomic elements like emotions, beliefs and neuroscientific constraints and exports improved testable predictions. The typical structure of neuroeconomic proof of economic models and the imprecise neuroscientific measurement let us suggest a feed-back structure of economic research. We apply Hirshleifer's conception of macro-/micro-technology and contrast it to the neuroeconomic black box critique on economic theory. Furthermore, instead of direct adjustment of preference structures we propose the auxiliary creation of neuroeconomic constraints like action-dependent or outcome-dependent neuroeconomic belief constraints (NBC) and emotion compatibility constraints (ECC). This prepares the ground for our examination of neuroeconomics and ERM as two different paths towards an analytical unification of behavioral sciences.

Combining Brain and Behavioral Data to Improve Econometric Policy Analysis

Human behaviour may be governed by rules, but it is possible that these rules simply encode preferences. [...] Many psychologists argue that behaviour is far too sensitive to context and affect to be usefully related to stable preferences. However, if there are underlying preferences, then even if the link from preferences to rules is quite noisy it may be possible to recover these preferences and use them to correctly evaluate economic policies, at least as an approximation that is good enough for government policy work.
Daniel L. McFadden (Nobel Prize Lecture 2002)

Abstract: For an economist, ultimate goals of neuroeconomic research include improving economic policy analysis. One path toward this goal is to use neuroeconomic data to advance economic theory, and productive efforts have been made towards that end. Equally important, though less studied, is how neuroeconomics can provide quantitative evidence on policy, and in particular the way in which it might inform structural econometric inference. This paper is a first step in that direction. We suggest here that key forms of preference (or decision strategy) heterogeneity can be identified by brain imaging studies and, consequently, linked stochastically to observable individual characteristics. Then, recognizing that brain-imaging studies are substantially costly, we derive conditions under which the probabilistic link between observable characteristics and type, a quantity critical to policy analysis, can be estimated more precisely by combining data from traditional and brain-based decision studies.

Aging and Neuroeconomics: Insights from Research on Neuromodulation of Reward-based Decision Making

Abstract: 'Neuroeconomics' can be broadly defined as the research of how the brain interacts with the environment to make decisions that are functional given individual and contextual constraints. Deciphering such brain-environment transactions requires mechanistic understandings of the neurobiological processes that implement value-dependent decision making. To this end, a common empirical approach is to investigate neural mechanisms of reward-based decision making. Flexible updating of choices and associated expected outcomes in ways that are adaptive for a given task (or a given set of tasks) at hand relies on dynamic neurochemical tuning of the brain’s functional circuitries involved in the representation of tasks, goals and reward prediction. Empirical evidence as well as computational theories indicate that various neurotransmitter systems (e.g., dopamine, norepinephrine, and serotonin) play important roles in reward-based decision making. In light of the apparent aging-related decline in various aspects of the dopaminergic system as well as the effects of neuromodulation on reward-related processes, this article focuses selectively on the literature that highlights the triadic relations between dopaminergic modulation, reward-based decision making, and aging. Directions for future research on aging and neuroeconomoics are discussed.
