While sharing many theoretical and psychologically based tools with behavioural macroeconomics, our contribution does not have the aim of proposing more empirically robust foundations for macroeconomics or for the business cycle. Farmer, R, J Doyne and D Foley (2009), “The economy needs agent-based modelling”, Nature 460: 685-686. We achieve this without the need to invoke common exogenous shocks (De Grauwe and Ji 2016).

We also found, however, that there is a limit to the comfort flexibility can provide to central bankers. Research-based policy analysis and commentary from leading economists, Behavioural economics is also useful in macroeconomics, Paul De Grauwe, Yuemei Ji 01 November 2017. 2005, Tesfatsion and Judd 2006, Colander et al. Therefore, economics is the foundation of behavioral economics. Presently, many macroeconomic models, representing different theories, [4] are derived by aggregating microeconomic models allowing economists to test them with both macroeconomic and … 1.2 Behaviour. Behavioural research explains human behaviour through the lens of social preferences, heuristics and norms, … 0000003666 00000 n This point is obtained when flexibility is zero (i.e. Westerhoff, F and R Franke (2012), “Agent-based models for economic policy design: Two illustrative examples”, Iowa State University, Working Paper No 88. We need to do better – and that is what we have been trying to do in a series of publications (De Grauwe 2012, De Grauwe and Corrado 2015, De Grauwe and Ji 2016, 2017a). Figure 1 Trade-off between output and inflation. Journal of Monetary Economics 61: 2-22. wages and prices do not react to changes in the output gap). This column uses concepts from behavioural economics to develop macroeconomic models with endogenous business cycle fluctuations. Behavioral Foundations for Keynesian Macroeconomics: The Consumption Function 0000002948 00000 n The foundation’s Behavioral Economics program supports research that uses insights and methods from psychology, economics, sociology, political science and other social sciences to examine and improve social and living conditions in the United States. In particular, in a more flexible economy (more wage and price flexibility), the power of animal spirits is reduced and so is the potential for booms and busts in the economy. For values of b2 exceeding 0.5, these trade-offs become positively sloped – that is, when c1 (the inflation parameter in the Taylor rule) increases, both inflation and output volatility decline. AKERLOF: BEHAVIORAL MACROECONOMICS In what follows I shall describe how behav-ioral macroeconomists, incorporating realistic assumptions grounded in psychological and so-ciological observation, have produced models that comfortably account for each of these mac-roeconomic phenomena. This feature of the higher moments of the output gap is generated endogenously in the model.

There is a growing number of researchers developing ‘agent-based’ models and ‘behavioural’ macroeconomic models (Alfarano et al.

Executive Summary This thesis strives to enrich macroeconomic theories with behavioural components. This briefing distils many concepts from behavioural economics and psychology down to seven key principles, which highlight the main shortfalls in the neoclassical model of human behaviour. 0000007571 00000 n 0000012341 00000 n The horizontal axis shows the standard deviations of output; the vertical axis the standard deviations of inflation. This is much less the case in mainstream macroeconomics, however. Behavioral Foundations for Keynesian Macroeconomics: The Consumption Function Fabio D’Orlando and Eleonora Sanfilippo∗ Preliminary Draft Abstract This paper aims to discuss: (i) the presence of behavioral assumptions in Keynes’s General Theory; and (ii) the possibility of grounding a Keynesian-type consumption function From the liberal arts perspective, this includes the fields of psychology, sociology, anthropology, economics and behavioral economics. One good example is the recent effort to integrate the financial sector in DSGE models to explain the business cycle. It can be argued that in a world of great complexity that nobody fully understands, such a process of adaptive learning might be the rational way of deal handling this complexity (Simon 1957, Gigerenzer and Selten 2002, Ackerlof and Shiller2009). As the degree of flexibility increases, we observe that the trade-off curves shift to the left and become less negatively sloped. 0000002883 00000 n Behavioural economics is a rather recent field of mainstream economics; it predominantly deals with human behaviour’s deviations from the model of the homo economicus or rational man. This adaptive learning assumption introduced in an otherwise standard New Keynesian macroeconomic model produces endogenous waves of optimism and pessimism (animal spirits) that drive the business cycle in a self-fulfilling way. These models find it difficult to explain the fat tails in the distribution of the output gap. 0000012210 00000 n "—Domenico Delli Gatti, Journal of Economic Literature "De Grauwe voices the concerns of many macroeconomists regarding the empirical plausibility of the rational expectations assumption.

It is not the result of imposing such a feature on the stochastic shocks hitting the economy. 0000008314 00000 n These come close to the observed correlations. 0000003968 00000 n An important feature of this dynamics of animal spirits is that the movements of the output gap are characterised by periods of tranquility alternating in an unpredictable way with periods of intense movements reflecting booms and busts.

Behavioral Macroeconomics Via Sparse Dynamic Programming Xavier Gabaix March 16, 2017 Abstract This paper proposes a tractable way to model boundedly rational dynamic programming. The force of this criticism has been reduced by the second reason for incorporating behavioral economics results into macroeconomics: cognitive psychologists and experimental economists have documented a number of systematic deviations between the decisions of human beings and those of the “economic man.” In classical economics, most models assume that consumers behave rationally. 2014, Cacciatore et al. 2013, ECB 2015). 0000002410 00000 n Akerlof, G and R Shiller (2009) Animal spirits: How human psychology drives the economy and why it matters for global capitalism, Princeton University Press. That is, optimism (pessimism) leads to an increase (decline) in output, and the increase (decline) in output in term intensifies optimism (pessimism) (De Grauwe 2012, De Grauwe and Ji 2017a).

We find that structural reforms that increase the flexibility of wages and prices can have profound effects on the dynamics of the business cycle. 2012, Everaert and Schule 2006, Gomes et al. In order to understand this, start from point A.

We also found, however, that there is a limit to the comfort flexibility can provide to central bankers. Research-based policy analysis and commentary from leading economists, Behavioural economics is also useful in macroeconomics, Paul De Grauwe, Yuemei Ji 01 November 2017. 2005, Tesfatsion and Judd 2006, Colander et al. Therefore, economics is the foundation of behavioral economics. Presently, many macroeconomic models, representing different theories, [4] are derived by aggregating microeconomic models allowing economists to test them with both macroeconomic and … 1.2 Behaviour. Behavioural research explains human behaviour through the lens of social preferences, heuristics and norms, … 0000003666 00000 n This point is obtained when flexibility is zero (i.e. Westerhoff, F and R Franke (2012), “Agent-based models for economic policy design: Two illustrative examples”, Iowa State University, Working Paper No 88. We need to do better – and that is what we have been trying to do in a series of publications (De Grauwe 2012, De Grauwe and Corrado 2015, De Grauwe and Ji 2016, 2017a). Figure 1 Trade-off between output and inflation. Journal of Monetary Economics 61: 2-22. wages and prices do not react to changes in the output gap). This column uses concepts from behavioural economics to develop macroeconomic models with endogenous business cycle fluctuations. Behavioral Foundations for Keynesian Macroeconomics: The Consumption Function 0000002948 00000 n The foundation’s Behavioral Economics program supports research that uses insights and methods from psychology, economics, sociology, political science and other social sciences to examine and improve social and living conditions in the United States. In particular, in a more flexible economy (more wage and price flexibility), the power of animal spirits is reduced and so is the potential for booms and busts in the economy. For values of b2 exceeding 0.5, these trade-offs become positively sloped – that is, when c1 (the inflation parameter in the Taylor rule) increases, both inflation and output volatility decline. AKERLOF: BEHAVIORAL MACROECONOMICS In what follows I shall describe how behav-ioral macroeconomists, incorporating realistic assumptions grounded in psychological and so-ciological observation, have produced models that comfortably account for each of these mac-roeconomic phenomena. This feature of the higher moments of the output gap is generated endogenously in the model.

Executive Summary This thesis strives to enrich macroeconomic theories with behavioural components. This briefing distils many concepts from behavioural economics and psychology down to seven key principles, which highlight the main shortfalls in the neoclassical model of human behaviour. 0000007571 00000 n 0000012341 00000 n The horizontal axis shows the standard deviations of output; the vertical axis the standard deviations of inflation. This is much less the case in mainstream macroeconomics, however. Behavioral Foundations for Keynesian Macroeconomics: The Consumption Function Fabio D’Orlando and Eleonora Sanfilippo∗ Preliminary Draft Abstract This paper aims to discuss: (i) the presence of behavioral assumptions in Keynes’s General Theory; and (ii) the possibility of grounding a Keynesian-type consumption function From the liberal arts perspective, this includes the fields of psychology, sociology, anthropology, economics and behavioral economics. One good example is the recent effort to integrate the financial sector in DSGE models to explain the business cycle. It can be argued that in a world of great complexity that nobody fully understands, such a process of adaptive learning might be the rational way of deal handling this complexity (Simon 1957, Gigerenzer and Selten 2002, Ackerlof and Shiller2009). As the degree of flexibility increases, we observe that the trade-off curves shift to the left and become less negatively sloped. 0000002883 00000 n Behavioural economics is a rather recent field of mainstream economics; it predominantly deals with human behaviour’s deviations from the model of the homo economicus or rational man. This adaptive learning assumption introduced in an otherwise standard New Keynesian macroeconomic model produces endogenous waves of optimism and pessimism (animal spirits) that drive the business cycle in a self-fulfilling way. These models find it difficult to explain the fat tails in the distribution of the output gap. 0000012210 00000 n "—Domenico Delli Gatti, Journal of Economic Literature "De Grauwe voices the concerns of many macroeconomists regarding the empirical plausibility of the rational expectations assumption.

Behavioral Macroeconomics Via Sparse Dynamic Programming Xavier Gabaix March 16, 2017 Abstract This paper proposes a tractable way to model boundedly rational dynamic programming. The force of this criticism has been reduced by the second reason for incorporating behavioral economics results into macroeconomics: cognitive psychologists and experimental economists have documented a number of systematic deviations between the decisions of human beings and those of the “economic man.” In classical economics, most models assume that consumers behave rationally. 2014, Cacciatore et al. 2013, ECB 2015). 0000002410 00000 n Akerlof, G and R Shiller (2009) Animal spirits: How human psychology drives the economy and why it matters for global capitalism, Princeton University Press. That is, optimism (pessimism) leads to an increase (decline) in output, and the increase (decline) in output in term intensifies optimism (pessimism) (De Grauwe 2012, De Grauwe and Ji 2017a).

We find that structural reforms that increase the flexibility of wages and prices can have profound effects on the dynamics of the business cycle. 2012, Everaert and Schule 2006, Gomes et al. In order to understand this, start from point A.

While sharing many theoretical and psychologically based tools with behavioural macroeconomics, our contribution does not have the aim of proposing more empirically robust foundations for macroeconomics or for the business cycle. Farmer, R, J Doyne and D Foley (2009), “The economy needs agent-based modelling”, Nature 460: 685-686. We achieve this without the need to invoke common exogenous shocks (De Grauwe and Ji 2016).

We also found, however, that there is a limit to the comfort flexibility can provide to central bankers. Research-based policy analysis and commentary from leading economists, Behavioural economics is also useful in macroeconomics, Paul De Grauwe, Yuemei Ji 01 November 2017. 2005, Tesfatsion and Judd 2006, Colander et al. Therefore, economics is the foundation of behavioral economics. Presently, many macroeconomic models, representing different theories, [4] are derived by aggregating microeconomic models allowing economists to test them with both macroeconomic and … 1.2 Behaviour.

We need to do better – and that is what we have been trying to do in a series of publications (De Grauwe 2012, De Grauwe and Corrado 2015, De Grauwe and Ji 2016, 2017a). Figure 1 Trade-off between output and inflation. Journal of Monetary Economics 61: 2-22. wages and prices do not react to changes in the output gap). This column uses concepts from behavioural economics to develop macroeconomic models with endogenous business cycle fluctuations. Behavioral Foundations for Keynesian Macroeconomics: The Consumption Function 0000002948 00000 n The foundation’s Behavioral Economics program supports research that uses insights and methods from psychology, economics, sociology, political science and other social sciences to examine and improve social and living conditions in the United States. In particular, in a more flexible economy (more wage and price flexibility), the power of animal spirits is reduced and so is the potential for booms and busts in the economy. For values of b2 exceeding 0.5, these trade-offs become positively sloped – that is, when c1 (the inflation parameter in the Taylor rule) increases, both inflation and output volatility decline. AKERLOF: BEHAVIORAL MACROECONOMICS In what follows I shall describe how behav-ioral macroeconomists, incorporating realistic assumptions grounded in psychological and so-ciological observation, have produced models that comfortably account for each of these mac-roeconomic phenomena. This feature of the higher moments of the output gap is generated endogenously in the model.

Executive Summary This thesis strives to enrich macroeconomic theories with behavioural components. This briefing distils many concepts from behavioural economics and psychology down to seven key principles, which highlight the main shortfalls in the neoclassical model of human behaviour. 0000007571 00000 n 0000012341 00000 n The horizontal axis shows the standard deviations of output; the vertical axis the standard deviations of inflation. This is much less the case in mainstream macroeconomics, however. Behavioral Foundations for Keynesian Macroeconomics: The Consumption Function Fabio D’Orlando and Eleonora Sanfilippo∗ Preliminary Draft Abstract This paper aims to discuss: (i) the presence of behavioral assumptions in Keynes’s General Theory; and (ii) the possibility of grounding a Keynesian-type consumption function From the liberal arts perspective, this includes the fields of psychology, sociology, anthropology, economics and behavioral economics. One good example is the recent effort to integrate the financial sector in DSGE models to explain the business cycle. It can be argued that in a world of great complexity that nobody fully understands, such a process of adaptive learning might be the rational way of deal handling this complexity (Simon 1957, Gigerenzer and Selten 2002, Ackerlof and Shiller2009). As the degree of flexibility increases, we observe that the trade-off curves shift to the left and become less negatively sloped. 0000002883 00000 n Behavioural economics is a rather recent field of mainstream economics; it predominantly deals with human behaviour’s deviations from the model of the homo economicus or rational man. This adaptive learning assumption introduced in an otherwise standard New Keynesian macroeconomic model produces endogenous waves of optimism and pessimism (animal spirits) that drive the business cycle in a self-fulfilling way. These models find it difficult to explain the fat tails in the distribution of the output gap. 0000012210 00000 n "—Domenico Delli Gatti, Journal of Economic Literature "De Grauwe voices the concerns of many macroeconomists regarding the empirical plausibility of the rational expectations assumption.

Behavioral Macroeconomics Via Sparse Dynamic Programming Xavier Gabaix March 16, 2017 Abstract This paper proposes a tractable way to model boundedly rational dynamic programming. The force of this criticism has been reduced by the second reason for incorporating behavioral economics results into macroeconomics: cognitive psychologists and experimental economists have documented a number of systematic deviations between the decisions of human beings and those of the “economic man.” In classical economics, most models assume that consumers behave rationally. 2014, Cacciatore et al. 2013, ECB 2015). 0000002410 00000 n Akerlof, G and R Shiller (2009) Animal spirits: How human psychology drives the economy and why it matters for global capitalism, Princeton University Press. That is, optimism (pessimism) leads to an increase (decline) in output, and the increase (decline) in output in term intensifies optimism (pessimism) (De Grauwe 2012, De Grauwe and Ji 2017a).

We find that structural reforms that increase the flexibility of wages and prices can have profound effects on the dynamics of the business cycle. 2012, Everaert and Schule 2006, Gomes et al.

While sharing many theoretical and psychologically based tools with behavioural macroeconomics, our contribution does not have the aim of proposing more empirically robust foundations for macroeconomics or for the business cycle. Farmer, R, J Doyne and D Foley (2009), “The economy needs agent-based modelling”, Nature 460: 685-686. We achieve this without the need to invoke common exogenous shocks (De Grauwe and Ji 2016).

We also found, however, that there is a limit to the comfort flexibility can provide to central bankers. Research-based policy analysis and commentary from leading economists, Behavioural economics is also useful in macroeconomics, Paul De Grauwe, Yuemei Ji 01 November 2017. 2005, Tesfatsion and Judd 2006, Colander et al. Therefore, economics is the foundation of behavioral economics. Presently, many macroeconomic models, representing different theories, [4] are derived by aggregating microeconomic models allowing economists to test them with both macroeconomic and … 1.2 Behaviour.

We need to do better – and that is what we have been trying to do in a series of publications (De Grauwe 2012, De Grauwe and Corrado 2015, De Grauwe and Ji 2016, 2017a). Figure 1 Trade-off between output and inflation. Journal of Monetary Economics 61: 2-22. wages and prices do not react to changes in the output gap). This column uses concepts from behavioural economics to develop macroeconomic models with endogenous business cycle fluctuations. Behavioral Foundations for Keynesian Macroeconomics: The Consumption Function 0000002948 00000 n The foundation’s Behavioral Economics program supports research that uses insights and methods from psychology, economics, sociology, political science and other social sciences to examine and improve social and living conditions in the United States. In particular, in a more flexible economy (more wage and price flexibility), the power of animal spirits is reduced and so is the potential for booms and busts in the economy. For values of b2 exceeding 0.5, these trade-offs become positively sloped – that is, when c1 (the inflation parameter in the Taylor rule) increases, both inflation and output volatility decline. AKERLOF: BEHAVIORAL MACROECONOMICS In what follows I shall describe how behav-ioral macroeconomists, incorporating realistic assumptions grounded in psychological and so-ciological observation, have produced models that comfortably account for each of these mac-roeconomic phenomena. This feature of the higher moments of the output gap is generated endogenously in the model.

Executive Summary This thesis strives to enrich macroeconomic theories with behavioural components. This briefing distils many concepts from behavioural economics and psychology down to seven key principles, which highlight the main shortfalls in the neoclassical model of human behaviour. 0000007571 00000 n 0000012341 00000 n The horizontal axis shows the standard deviations of output; the vertical axis the standard deviations of inflation. This is much less the case in mainstream macroeconomics, however. Behavioral Foundations for Keynesian Macroeconomics: The Consumption Function Fabio D’Orlando and Eleonora Sanfilippo∗ Preliminary Draft Abstract This paper aims to discuss: (i) the presence of behavioral assumptions in Keynes’s General Theory; and (ii) the possibility of grounding a Keynesian-type consumption function From the liberal arts perspective, this includes the fields of psychology, sociology, anthropology, economics and behavioral economics. One good example is the recent effort to integrate the financial sector in DSGE models to explain the business cycle. It can be argued that in a world of great complexity that nobody fully understands, such a process of adaptive learning might be the rational way of deal handling this complexity (Simon 1957, Gigerenzer and Selten 2002, Ackerlof and Shiller2009). As the degree of flexibility increases, we observe that the trade-off curves shift to the left and become less negatively sloped. 0000002883 00000 n Behavioural economics is a rather recent field of mainstream economics; it predominantly deals with human behaviour’s deviations from the model of the homo economicus or rational man. This adaptive learning assumption introduced in an otherwise standard New Keynesian macroeconomic model produces endogenous waves of optimism and pessimism (animal spirits) that drive the business cycle in a self-fulfilling way. These models find it difficult to explain the fat tails in the distribution of the output gap. 0000012210 00000 n "—Domenico Delli Gatti, Journal of Economic Literature "De Grauwe voices the concerns of many macroeconomists regarding the empirical plausibility of the rational expectations assumption.

Behavioral Macroeconomics Via Sparse Dynamic Programming Xavier Gabaix March 16, 2017 Abstract This paper proposes a tractable way to model boundedly rational dynamic programming. The force of this criticism has been reduced by the second reason for incorporating behavioral economics results into macroeconomics: cognitive psychologists and experimental economists have documented a number of systematic deviations between the decisions of human beings and those of the “economic man.” In classical economics, most models assume that consumers behave rationally. 2014, Cacciatore et al. 2013, ECB 2015). 0000002410 00000 n Akerlof, G and R Shiller (2009) Animal spirits: How human psychology drives the economy and why it matters for global capitalism, Princeton University Press. That is, optimism (pessimism) leads to an increase (decline) in output, and the increase (decline) in output in term intensifies optimism (pessimism) (De Grauwe 2012, De Grauwe and Ji 2017a).

We find that structural reforms that increase the flexibility of wages and prices can have profound effects on the dynamics of the business cycle. 2012, Everaert and Schule 2006, Gomes et al.

As we increase the degree of flexibility, we move down along the downward sloping segment of the line. These reforms lead to a lowering of mark ups in the goods and labour markets and move the economy closer to perfect competition. 0000004230 00000 n The agent uses an endogenously simpli ed, or \sparse," model of the world and the conse-quences of his actions and acts according to a behavioral Bellman equation. 0000006898 00000 n 0000004350 00000 n These measure the inflation and output volatility choices the central bank faces when it increases its inflation control (measured by the sensitivity of the interest rate to changes in inflation in the Taylor rule). 0000003600 00000 n In order to do so, we constructed policy trade-offs of the central bank for different levels of flexibility. 2008, Farmer 2006, Farmer and Foley 2009, Gatti et al.

We conclude that the degree of flexibility has profound effects on the trade-offs central banks encounter in their attempts to stabilise the economy. This evaluation leads them to switch to the rules that perform best. Thus, our behavioural model predicts that in the real world the output gap does not follow a normal distribution, but is characterised by excess kurtosis and fat tails. The trade-offs are represented in Figure 1. Behavioral economics uses the the behavioral insights of psychology to improve economists’ models and the predictions they make.

We also found, however, that there is a limit to the comfort flexibility can provide to central bankers. Research-based policy analysis and commentary from leading economists, Behavioural economics is also useful in macroeconomics, Paul De Grauwe, Yuemei Ji 01 November 2017. 2005, Tesfatsion and Judd 2006, Colander et al. Therefore, economics is the foundation of behavioral economics. Presently, many macroeconomic models, representing different theories, [4] are derived by aggregating microeconomic models allowing economists to test them with both macroeconomic and … 1.2 Behaviour.

We need to do better – and that is what we have been trying to do in a series of publications (De Grauwe 2012, De Grauwe and Corrado 2015, De Grauwe and Ji 2016, 2017a). Figure 1 Trade-off between output and inflation. Journal of Monetary Economics 61: 2-22. wages and prices do not react to changes in the output gap). This column uses concepts from behavioural economics to develop macroeconomic models with endogenous business cycle fluctuations. Behavioral Foundations for Keynesian Macroeconomics: The Consumption Function 0000002948 00000 n The foundation’s Behavioral Economics program supports research that uses insights and methods from psychology, economics, sociology, political science and other social sciences to examine and improve social and living conditions in the United States. In particular, in a more flexible economy (more wage and price flexibility), the power of animal spirits is reduced and so is the potential for booms and busts in the economy. For values of b2 exceeding 0.5, these trade-offs become positively sloped – that is, when c1 (the inflation parameter in the Taylor rule) increases, both inflation and output volatility decline. AKERLOF: BEHAVIORAL MACROECONOMICS In what follows I shall describe how behav-ioral macroeconomists, incorporating realistic assumptions grounded in psychological and so-ciological observation, have produced models that comfortably account for each of these mac-roeconomic phenomena.

Executive Summary This thesis strives to enrich macroeconomic theories with behavioural components.

This is much less the case in mainstream macroeconomics, however. Behavioral Foundations for Keynesian Macroeconomics: The Consumption Function Fabio D’Orlando and Eleonora Sanfilippo∗ Preliminary Draft Abstract This paper aims to discuss: (i) the presence of behavioral assumptions in Keynes’s General Theory; and (ii) the possibility of grounding a Keynesian-type consumption function From the liberal arts perspective, this includes the fields of psychology, sociology, anthropology, economics and behavioral economics. One good example is the recent effort to integrate the financial sector in DSGE models to explain the business cycle. It can be argued that in a world of great complexity that nobody fully understands, such a process of adaptive learning might be the rational way of deal handling this complexity (Simon 1957, Gigerenzer and Selten 2002, Ackerlof and Shiller2009). As the degree of flexibility increases, we observe that the trade-off curves shift to the left and become less negatively sloped. 0000002883 00000 n Behavioural economics is a rather recent field of mainstream economics; it predominantly deals with human behaviour’s deviations from the model of the homo economicus or rational man. This adaptive learning assumption introduced in an otherwise standard New Keynesian macroeconomic model produces endogenous waves of optimism and pessimism (animal spirits) that drive the business cycle in a self-fulfilling way. These models find it difficult to explain the fat tails in the distribution of the output gap. 0000012210 00000 n "—Domenico Delli Gatti, Journal of Economic Literature "De Grauwe voices the concerns of many macroeconomists regarding the empirical plausibility of the rational expectations assumption.

I shall begin my review by describing one of my ear- liest attempts in this fi eld, which led to the discovery of the role of asymmetric information in markets. It is not the result of imposing such a feature on the stochastic shocks hitting the economy. 0000008314 00000 n These come close to the observed correlations. 0000003968 00000 n An important feature of this dynamics of animal spirits is that the movements of the output gap are characterised by periods of tranquility alternating in an unpredictable way with periods of intense movements reflecting booms and busts.

Behavioral Macroeconomics Via Sparse Dynamic Programming Xavier Gabaix March 16, 2017 Abstract This paper proposes a tractable way to model boundedly rational dynamic programming. The force of this criticism has been reduced by the second reason for incorporating behavioral economics results into macroeconomics: cognitive psychologists and experimental economists have documented a number of systematic deviations between the decisions of human beings and those of the “economic man.” In classical economics, most models assume that consumers behave rationally. 2014, Cacciatore et al. 2013, ECB 2015). 0000002410 00000 n Akerlof, G and R Shiller (2009) Animal spirits: How human psychology drives the economy and why it matters for global capitalism, Princeton University Press. That is, optimism (pessimism) leads to an increase (decline) in output, and the increase (decline) in output in term intensifies optimism (pessimism) (De Grauwe 2012, De Grauwe and Ji 2017a). Figure 2 The optimal level of flexibility. 0000003307 00000 n These deviations from rational calculation are introduced as “non-standard” (the standard being neoclassical economics) or reflections of “bias”. 0000004481 00000 n �G��k>U'D���N��_�F�F,=��*ܙ���P��:�i_��^��}i��,�=�C����=�n�/��6��� ��Ņ11��Cљ7��\Ji��#�֧��n�xfsܷ���+㤈:�q$�� �6�:����I����)g��O>x��,y�z9J���䝙OW8�‡� In that case, the central bank can pursue a tighter inflation target without paying a price in terms of a higher output volatility. 2011, … 0000003050 00000 n If you want to take behavioral economics here, you can be admitted even if you do not have major in economics in your undergraduate because it is not required; however, micro and macroeconomic courses are significant. We find that structural reforms that increase the flexibility of wages and prices can have profound effects on the dynamics of the business cycle. 2012, Everaert and Schule 2006, Gomes et al. In order to understand this, start from point A. In the spirit of Keynes’ General Theory, behavioral macroeconomists are rebuilding the microfoundations that were sacked by the New Classical economics. 9.30 – 10.40 David 1: Welcome, Intro, & Methods in Behavioral Economics 11.00 – 12.10 Matthew 1: Normal-Science Behavioral Economics (& Camp Outline) 2.00 – 3.10 Matthew 2: Belief-Based Preferences & Intro to Prospect Theory 3.30 – 4.40 Matthew 3: Reference Dependence and News Utility New eBook: DSGE Models in the Conduct of Policy: Use as intended. There is a growing number of researchers developing ‘agent-based’ models and ‘behavioural’ macroeconomic models (Alfarano et al. Beyond the minimum point further increases in flexibility lead to lower output volatility at the expense of higher inflation volatility. However, the results of these models depend on the assumption that the shocks are serially-correlated. In this case, the trade-off is negatively sloped.
