The model therefore contains all the required ingredients that make a model achieve the Lucas’ project. Although simple, this stylized model captures the essence of most DSGE models and appears to contain all ingredients of the Lucasian project. "Macroeconomics is a complex evolving system of thinking. While the modern DSGE models derive the Phillips curve from an explicit optimization problem, it is not clear that they are doing any better than models à la Gray (1976) or Taylor (1980) in terms of micro-foundations of nominal rigidities. 8Does it mean that not much progress has been made? Sneessens, Henri. Macroeconomics tackles a very large spectrum of questions ranging from the standard growth and business cycle theories, to fiscal and monetary economics, labor market regulations, health and pension systems, redistribution, regulation of financial systems, understanding trade and the determination of exchange rates… The tools and methodology improvements that macroeconomists have witnessed and developed over the last 40 years led to a tremendous change in the way questions are tackled. 6where equations (1)-(3) denote, respectively, the IS curve, the New-Keynesian Phillips (NKP) curve and the monetary policy rule. Let us focus on the NKP curve. / Jim Luke. A brief history of macro How we got here. The answer is negative. parameters is well understood. In the sequel, I will try to give my (hopefully) honest point of view on this statement as an applied macroeconomist. Interestingly, 35 years later, the so-called Dynamic Stochastic General Equilibrium (DSGE) models, that are now commonly used in Central Banks to understand and predict the effects of monetary policy decisions, are still built in reference to the Lucas’ project. Macroeconomics is born. The purpose here is not to go back to this debate, but rather to show how macroeconomics reacted to these attacks. (2015) and Nimark (2014) develop alternative models in which shocks capturing “animal spirits” play a non trivial role. regulations, health and pension systems, redistribution, regulation of financial systems, understanding trade and the determination of exchange rates… The tools and methodology improvements that macroeconomists have witnessed and developed over the last 40 years led to a tremendous change in the way questions are tackled. Miméo Banque de France. In particular, that models be micro-founded is now a clear and not to be discussed requirement. At the core, modern macroeconomic theory is relatively empty and vacuous when it comes to the major crises: last year’s melt-down, the Great Depression, the many bubbles, etc. Miméo University of Luxembourg. King, Robert G., Charles I. Plosser, and Sergio T. Rebelo. This approach was recently applied by Gornemann et al. Journal of Monetary Economics, 2(2): 221-235. 2010. The crisis is forcing macroeconomists to remake their field. 2016. 1998. Journal of Monetary Economics, 21(2-3), 195-232. Angeletos, Georges Marios, Fabrice Collard, and Harris Dellas. But even more importantly this makes us realize how much we still need to achieve. probability of resetting their price in a given period. But as a methodological approach to economic problems, it originated with the Mercantilists in the 16th and 17th centuries. For example, Boissay et al. This problem was addressed in the, literature developed by Sims (2010), which explicitly takes into account the limited cognitive abilities of agents through an entropy constraint (see, , 2015). In that sense, macroeconomics attempts to satisfy the falsifiability principle that characterizes hard sciences. While the preceding literature essentially focused on the observability of the state of the economy, it is as likely possible to take into account that fact that the agents are uncertain about the model. Journal of Economic Dynamics and Control, 35(2): 175-252. 1998. Indeed, most financial crises involve a credit crunch, which imply a discrete jump, and hence a non-differentiability in the evolution of credit that perturbation techniques cannot accommodate. in unique equilibrium, rational expectations models. We are then back to the seventies. The ‘invisible hand’ in the free markets automatically assigns resources to places where they are best utilized. So what about our three equations model? 2. Although complex macroeconomic structures have been characteristic of human... Keynesianism. He is confident that he has found the key not only to understanding the Great Depression but also to correcting it. Boissay, Frédéric, Fabrice Collard, and Frank Smets. One reason for this failure is again technological. The History of Macroeconomics from Keynes’s General Theory to the Present Michel De Vroey and Pierre Malgrange June 2011 Abstract This paper is a contribution to the forthcoming Edward Elgar Handbook of the History of Economic Analysis volume edited by Gilbert Faccarello and Heinz Kurz. But economist Milton Friedman of the University of Chicago continues to fight a lonely battle against what has become the Keynesian orthodoxy. Using a similar approach, Challe et al. Models featuring endogenous risk and liquidity spirals explain the observed financial instability, and can explain why downturns can be deep. This history of macroeconomics is not only backward looking, it is, like modern macroeconomics, forward looking. During booms, bank market funding and credit supply increase, which pushes down the rates of return on corporate and interbank loans. But, agents actually do not need to be fully informed to take decisions. AccueilNuméros6-1Symposium on Michel De Vroey's “A...A History of Macroeconomics: A Ma... Michel De Vroey, A History of Macroeconomics from Keynes to Lucas and Beyond, Cambridge: Cambridge University Press, 2015, 445 pages, ISBN: 9781107584945. Robustness. The first typical examples of models that fulfills these requirements are given by the Real Business Cycle (RBC) model proposed by Kydland and Prescott (1982) and King et al. Since, much progress has been made. macroeconomics, the major ideas in this subject developed around it. Collard, Fabrice, Harris Dellas, and Frank Smets. Keynesian thought was criticized by Friedman and the monetarists Article. Mark Donoghue . Both equations are dynamic, featuring both a backward and a forward looking component. Journal of Political Economy, Forthcoming. Challe, Edouard and Xavier Ragot. 1982. In the real sense, early economists focused on a single element such as the monetary/fiscal policy or the effect of weather on the agricultural economy and failed to concentrate on the interplay of goods and services, and the sellers and buy… Econometric policy evaluation: A critique. In that respect, the literature reacted quite fast and the number of contributions studying the impact of financial frictions on the business cycle sky-rocketted (see Brunnermeier et al. Boissay, Frédéric, Fabrice Collard, and Frank Smets. A group of economists (notably John Hicks, Franco Modigliani, and Paul Samuelson), attempted to interpret and formalize Keynes' writings, and to synthesize it with the neo-classical models of economics. Although their ideas clashed sharply, and although there remains considerable disagreement among economists about a variety of issues, a broad consensus among economists concerning macroeconomic policy seemed to emerge in the 1980s, 1990s, and early 2000s. (2015) estimate a full-fledged New Keynesian DSGE model by Bayesian maximum likelihood. A History of Macroeconomics Krishan Sharma M.Phil (Applied Economics) Centre for Development Studies Jawaharlal Nehru University. One commonly heard argument against the macroeconomic models were their inability to talk about the financial aspects of the business cycle. Precautionary Saving and Aggregate Demand. Judd, Kenneth J. 3, chapter 4, 155-181. Seen through the lenses of the previous statement, it satisfies the requirement. In that sense the book is as much a history of ideas in macroeconomics as a history of methodology. Second, like in most macro models, technological progress is given a key role in the long maturing process that led to current macroeconomics. Recently, Challe and Ragot (2011) proposed a modeling framework that preserves a limited heterogeneity and allows for tractability.

Computational Suite of Models with Heterogeneous Agents: Incomplete Markets and Aggregate Uncertainty. Fiscal Policy in a Tractable Liquidity-constrained Economy. The price setting behavior is derived from an explicit profit maximization problem at the firm level, and the so obtained price setting equation depends, in a non-linear way, on the psychological discount factor, β, the probability of resetting the price, α, and the degree of indexation of current inflation to past inflation, γ. Lucas, Robert E. Jr. 2007. Wage indexation: A macroeconomic approach. It is 1970. Distributional Consequences of Monetary Policy. They reach similar conclusions regarding the importance of these shocks. Many improvements have been (and still are) introduced over the recent years, addressing some of the concerns and critics that were raised against DSGE models. Second, because the mathematical language—while being extremely powerful—is somewhat limited, it has forced macroeconomists to narrow down, better focus and qualify the questions they address. All these parameters being specified at the micro level, they are deep parameters and the model is robust to the Lucas critique. Lucas, Robert E. Jr. 1976. Their approach proved useful to explain some observed cautious behavior in policy design or solve macro-finance problems (equity premium among others). Sims, Christopher A. Michel De Vroey's latest book dives into that evolving complexity and, by distinguishing between Marshallian and Walrasian macroeconomics, helps make the history of macroeconomics a bit more understandable.
