Application of the models highlights how the trade-off between output and inflation is moderated by the flexibility of the economy. The recent awarding of the Nobel Prize to Richard Thaler testifies that there has been a change of view within the economics profession on the need to allow for departures from the paradigm of the ‘homo economicus’. There are many ways in which one can depart from mainstream macroeconomic models. In order to do so, we constructed policy trade-offs of the central bank for different levels of flexibility. �3ȥ�(������g��a��g�� 0000006898 00000 n Chapter 4: The Transmission of Shocks . 2005, Tesfatsion and Judd 2006, Colander et al. The University offers grants to students who will conduct research about behavioral economics. One good example is the recent effort to integrate the financial sector in DSGE models to explain the business cycle.

De Grauwe, P (2012) Lectures on Behavioural Macroeconomics, Princeton University Press. 0000011518 00000 n This downward movement implies that increasing flexibility creates a ‘win-win’ situation in that both the volatility of output and inflation decline with increasing flexibility. In order to understand this, start from point A. 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.

Therefore, economics is the foundation of behavioral economics. We have used our behavioural macroeconomic model to analyse different macroeconomic issues. This has to do with the fact that in more flexible economies prices and wages have a greater role to play in adjustments to emerging disequilibria. 0000010067 00000 n This insight allows us to derive this new trade-off by connecting the points that are associated with the same inflation parameter of the Taylor rule. 2011, … In general, in more flexible economies central banks do not face the same kind of uncomfortable trade-offs as in rigid economies. Clearly, this must be located to the left of the minimum point of the relationship. For this purpose, laboratory experiments are conducted to investigate effects The economics of insurance and its borders with general finance, Maturity mismatch stretching: Banking has taken a wrong turn. However, when we go too far with structural reforms, we go beyond the minimum point on the line.

This may lead to the conclusion that flexibility is always welfare improving – but that is not the case. 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.” Gürkaynak, R and C Tille (2017), “DSGE models in the conduct of policy: Use as Intended”, VoxEU. Behavioral economics is the study of why people make decisions about money, including how they spend, invest, and save. Figure 2 allows us to obtain some insights about the optimal level of flexibility. Date: 15.-16. The horizontal axis shows the standard deviations of output; the vertical axis the standard deviations of inflation. 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. 0000012232 00000 n Therefore, these reforms can be seen as shifting the supply curve to the right, increasing the production potential of countries. Where the optimum flexibility will be reached then depends on the preferences about inflation versus output volatility. 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. The first is through the sensitivity of inflation to the output gap in the New Keynesian Philips curve (supply equation). 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. Instead, these agents use simple forecasting rules (heuristics) and evaluate the forecasting performances of these rules ex post. relates to the decision-making process behind an economic outcome of individuals and institutions Nothing really can go wrong in models populated by supreme agents peacefully optimising and endowed with great cognitive abilities that allow them to understand the complexities of the world. 0000003600 00000 n 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 Muellbauer, J (2016), “Macroeconomics and consumption”, CEPR Discussion paper 11588; Oxford University, Department of Economics working paper 811.

Thus, one can conclude that when the economy is very rigid, a central bank that pursues its inflation target with increasing intensity faces a classical negatively sloped trade-off between inflation and output volatility. This evaluation leads them to switch to the rules that perform best. 0000004416 00000 n In this case, the trade-off is negatively sloped. Homo economicus continues to reign supreme in dynamic stochastic general equilibrium (DSGE) models. 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. In fact, we can see from Figure 1 that the positively sloped ‘trade-offs’ move upward and to the left (indicated by the arrow) for increasing levels of flexibility (b2). 2014, Cacciatore et al. 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). We would always make optimal decisions. This feature of the higher moments of the output gap is generated endogenously in the model. It is not the result of imposing such a feature on the stochastic shocks hitting the economy. Frontiers of economic research Macroeconomic policy, Tags:  0000003135 00000 n The second way we introduce structural reforms is through changes in the supply equation. 0000003242 00000 n We extended our behavioural model to two countries and found that the model is capable of generating a strong international transmission of animal spirits, which in turn leads to a strong correlation of business cycles. 0000004164 00000 n 0000005111 00000 n 0000003490 00000 n These come close to the observed correlations. In classical economics, most models assume that consumers behave rationally. Therefore, during recent decades macroeconomists have attempted to combine microeconomic models of household and business behavior to derive the relationships between macroeconomic variables. Blanchard, O (2017) “Do DSGE models have a future?” in R Gürkaynak and C Tille (eds), DSGE Models in the Conduct of Policy: Use as Intended, VoxEU ebook. 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). 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. We show the result for a given c1 = 1.5 (the inflation parameter) and c2 = 0.5 (the output parameter) in Figure 2. 0000004786 00000 n Beyond the minimum point further increases in flexibility lead to lower output volatility at the expense of higher inflation volatility. Darst. A DSGE model-based analysis of the short-term effects of structural reforms in labour and product markets”, OECD, Economics Department Working paper no 948. Such an explanation is not satisfactory, as it shifts the burden of explaining the business cycle to outside forces. This presents the relationship between output and inflation variability that we obtain for increasing levels of flexibility, assuming that the central bank keeps its inflation control constant. Macroeconomic studies emphasize decisions with a time dimension, such as various forms of investments.

"These Lectures on Behavioral Macroeconomics remind us that De Grauwe is also an excellent macroeconomic theorist and a wonderful narrator. 0000007571 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.

Starting from the top of that trade-off, we see that increasing the inflation control (measured by the inflation parameter c1 in the Taylor rule) leads to a decline of inflation volatility at the expense of more output volatility. We also found, however, that there is a limit to the comfort flexibility can provide to central bankers. 1.2 Behaviour.

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.
