Volatility As Link Between Risk and Memory in Economics, Econometrics and Neuroeconomics: an Application for the Bolivian Inflation Rate 1938 - 2012
Volatility as link between risk and memory in Economics, Econometrics and Neuroeconomics: an application for the Bolivian Inflation Rate 1938 - 2012 María Edith Chacón B. [email protected] Teacher and researcher CIDES – UMSA. La Paz, Bolivia. Ernesto Sheriff B. [email protected] Teacher and researcher CIDES – UMSA and UPB. La Paz, Bolivia. Experimental and Behavioral Economics: Other Neuroeconomics Econometrics: Time Series ABSTRACT This paper provides an indicator that measures memory as a stock. Memory affects economic decisions thus the memory indicator is useful to help in applied work, it was built according to the state of the art in Psychology and Neuroeconomics and it is presented as a time series; it is a recursive one and it is represented by an accumulated measure of the volatility. Many theories of risk have used volatility indicators to represent risk in the applied work. Risk valuation is associated to volatility and it is very sensitive to periods in which it is measured; it is very sensitive too to the type of data associated to volatility. In this paper we found that the memory affects risk valuations and the link between them is a special kind of volatility i.e. accumulated volatility with an endogenous initialization period and compatible with many Psychological hypotheses. The developed indicator is compatible with the econometrics of stationary series, integrated series and fractional integrated series. These contributions help to improve the study of hysteresis in applied economics, to develop more consistent links between memory and risk in Neuroeconomics and, to obtain more confident time series models in econometrics using the new indicator. -
Punishment in the Cingulate Cortex Segregated and Integrated Coding
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2009 Segregated and integrated coding of reward and punishment in the cingulate cortex Fujiwara, J ; Tobler, Philippe N ; Taira, M ; Iijima, T ; Tsutsui, K I Abstract: Reward and punishment have opposite affective value but are both processed by the cingulate cortex. However, it is unclear whether the positive and negative affective values of monetary reward and punishment are processed by separate or common subregions of the cingulate cortex. We performed a functional magnetic resonance imaging study using a free-choice task and compared cingulate activations for different levels of monetary gain and loss. Gain-specific activation (increasing activation for increasing gain, but no activation change in relation to loss) occurred mainly in the anterior part of the anterior cingulate and in the posterior cingulate cortex. Conversely, loss-specific activation (increasing activation for increasing loss, but no activation change in relation to gain) occurred between these areas, in the middle and posterior part of the anterior cingulate. Integrated coding of gain and loss (increasing activation throughout the full range, from biggest loss to biggest gain) occurred in the dorsal part of the anterior cingulate, at the border with the medial prefrontal cortex. Finally, unspecific activation increases to both gains and losses (increasing activation to increasing gains and increasing losses, possibly reflecting attention) occurred in dorsal and middle regions of the cingulate cortex. Together, these results suggest separate and common coding of monetary reward and punishment in distinct subregions of the cingulate cortex. -

Such cognitive biases can serve as a barrier to trade. This study’s survey-based experiments, which include hypothetical emissions trading scenarios, show that the endowment effect does occur in emissions trading. The status quo bias occurs in only one of the three experiments. This study also investigates whether accumulation of experience can reduce cognitive bias as discovered preference hypothesis expects. The results indicate that practitioners who are supposed to have more experience show no evidence of having less cognitive bias. Contrary to the conventional expectation, the practitioners show significantly higher level of endowment effect than students and only the practitioners show a significant status quo bias. A consignment auction situation, which is used in California’s cap-and-trade program, is also tested; no significant difference between general permission trading and consignment auctions is found. Keywords: emissions trading; cognitive bias; consignment auction; climate policy 1. Introduction Emissions trading allows entities to achieve emission reduction targets in a cost-effective way through buying and selling emission allowances in emissions trading markets [1,2]. -

The Future of Economics in a Lakatos–Bourdieu Framework

Will the World Financial Crisis turn out to be that ‘experimentum crucis’ which triggered a scientific revolution? In this paper, we seek to assess the likelihood of a paradigm shift towards heterodox approaches and a more pluralist setting in economics emerging from the academic establishment in the U.S. – that is, from the dominant center of knowledge production in the economic disci- pline. This will be done by building the analysis on a combined Lakatosian framework of ‘battle of research programmes’ and a Bourdieuian framework of ‘power struggle’ within the academic field and highlighting the likelihood of two main proponents of the mainstream elite to become the promulgator of change?

Intertemporal Consumption and Savings Behavior: Neoclassical, Behavioral, and Neuroeconomic Approaches
Intertemporal Consumption and Savings Behavior: Neoclassical, Behavioral, and Neuroeconomic Approaches Joshua J. Kim June 2014 Abstract This paper summarizes neoclassical, behavioral, and neuroeconomic models of intertemporal consumption and savings behavior. I summarize the construction and implications of Modigliani & Brumberg's Life-Cycle Hypothesis [4] and Laibson's quasi-hyperbolic consumption function [8] as background and motivation for Bisin & Benhabib's neuroeconomic model of dynamic consumption behavior [3]. In particular, I focus on the mathe- matical construction of each model, their different behavioral assumptions of agent rationality, and the resulting implications for economic theory. 1 The Neoclassical Life-Cycle Hypothesis The development of modern economic theories analyzing intertemporal consumption began in the early 1950s with the publication of Modigliani & Brumberg's Life-cycle Hypothesis (LCH) [4]. By making several arguably innocuous assumptions, Modigliani & Brumberg produce several important and non-trival predictions about macroeconomic processes such as the relationship in aggregate economics between savings and growth. Furthermore, since its construction, the LCH has served as the standard economic approach to the study of consumption and savings behavior and has served as a foundational basis for subsequent models of intertemporal consumption. The structure of the rest of this chapter is as follows: subsection 1.1 presents the theoretical foundations and assumptions of the LCH. Subsection 1.2 discusses some of the implications and results. Subsection 1.3 concludes the discussion on neoclassical models of intertemporal consumption and discusses several objections and limitations of the LCH. 1 1.1 Theoretical Foundations Before we begin the construction of the life-cycle hypothesis, let us first define a few terms that readers unfamiliar with economic theory may not know. -
Reduced Loss Aversion in Pathological Gambling and Alcohol Dependence Is Associated with Differential Alterations in Amygdala An
www.nature.com/scientificreports OPEN Reduced loss aversion in pathological gambling and alcohol dependence is associated with Received: 9 March 2017 Accepted: 13 November 2017 diferential alterations in amygdala Published: xx xx xxxx and prefrontal functioning Alexander Genauck 1,2, Saskia Quester1,3, Torsten Wüstenberg1, Chantal Mörsen1, Andreas Heinz1 & Nina Romanczuk-Seiferth 1 Diagnostic criteria for pathological gambling and alcohol dependence (AD) include repeated addictive behavior despite severe negative consequences. However, the concept of loss aversion (LA) as a facet of value-based decision making has not yet been used to directly compare these disorders. We hypothesized reduced LA in pathological gamblers (PG) and AD patients, correlation of LA with disorder severity, and reduced loss-related modulation of brain activity. 19 PG subjects, 15 AD patients and 17 healthy controls (HC) engaged in a LA task in a functional magnetic resonance imaging setting. Imaging analyses focused on neural gain and loss sensitivity in the meso-cortico-limbic network of the brain. Both PG and AD subjects showed reduced LA. AD subjects showed altered loss-related modulation of activity in lateral prefrontal regions. PG subjects showed indication of altered amygdala-prefrontal functional connectivity. Although we observed reduced LA in both a behavioral addiction and a substance-related disorder our neural fndings might challenge the notion of complete neuro-behavioral congruence of substance-use disorders and behavioral addictions. Value-based decisions are ubiquitous in every-day life. Tey can be anything from short-term and mundane (tea or cofee) to long-term and life changing (law or medical school). In all of these decisions we need to incorpo- rate magnitude, delay and probability of possible rewards and losses to compute subjective values of the availa- ble options1. -

We Stochastic choice provide analytical results showing that this model can generate systematically different choice Preference variability patterns from an exponential discounting model with a fixed discount factor. The variable ex- Computational modeling ponential model accounts for the common behavioral pattern of decreasing impatience, which is typically attributed to hyperbolic discounting. The variable exponential model also generates violations of strong stochastic transitivity in choices involving intertemporal dominance. We present the results of two experiments designed to evaluate the variable exponential model in terms of quantitative fit to individual-level choice data. Data from these experiments reveal that allowing for a variable discount factor significantly improves the fit of the exponential model, and that a variable exponential model provides a better account of individual-level choice probabilities than hyperbolic discounting models. In a third experiment we find evidence of strong stochastic transitivity violations when intertemporal dominance is involved, in accordance with the variable exponential model. Overall, our analytical and experimental results indicate that exponential discounting can explain intertemporal choice behavior that was supposed to be beyond its descriptive scope if the discount factor is permitted to vary at random.
