This has prompted us to examine the contents of the ‘old’ and the ‘new’ neoclassical syntheses. Our main conclusion is that the latter bears little resemblance with the former. Additionally, we make three points: (a) from its origins with Paul Samuelson onward the neoclassical synthesis notion had no fixed content and we bring out four main distinct meanings; (b) its most cogent interpretation, defended e.g. by Solow and Mankiw, is a plea for a pluralistic macroeconomics, wherein short-period market non-clearing models would live side by side with long-period market-clearing models; (c) a distinction should be drawn between first and second generation new Keynesian economists as the former defend the old neoclassical synthesis while the latter, with their DSGE models, adhere to the Lucasian view that macroeconomics should be based on a single baseline model.

Malgrange Discussion Paper 2011-28 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. Its aim is to introduce the reader to the main episodes that have marked the course of modern macroeconomics: its emergence after the publication of Keynes’s General Theory, the heydays of Keynesian macroeconomics based on the IS-LM model, disequilibrium and non-Walrasian equilibrium modelling, the invention of the natural rate of unemployment notion, the new classical attack against Keynesian macroeconomics, the first wave of new Keynesian models, real business cycle modelling and, finally, the second wage of new Keynesian models, i.e. DSGE models. A main thrust of the paper is the contrast we draw between Keynesian macroeconomics and stochastic dynamic general equilibrium macroeconomics. We hope that our paper will be useful for teachers of macroeconomics wishing to complement their technical material with a historical addendum.

    On the Concept of Nudging: Its Coherence and Applicability?

    On the Concept of Nudging: Its Coherence and Applicability? Mads Wistrup Freund September 15, 2017 25-June-1993-xxxx MSc in Business Administration and Philosophy Vejleder: Marius Gudman Høyer 1 Abstract The practice of nudging has attracted attention from researchers, policymakers, and practitioners alike. The contemporary interest in nudging has sparked demands for a clearer examination of the conditions under which nudging and other behavioral methods can be used efficiently and acceptable. There are several unresolved questions which may have contributed to heated political and scientific discussions, especially heated is the ethical discussion of applying nudging in the public policy domain. This thesis concentrate on the philosophical premises nudges are built on. It is argued that the model is philosophically problematic. Different interventions might operate through various logics that threaten not only effectiveness but also representativeness and ethical ends. This thesis aruges that the next step in advancing the acceptability nudging requires a clarification. The thesis investi- gates the internal logic of this practice by exploring the expositions and implications within the literature on nudging in public policy, by specifically exploring its origins in behavioral economics; its impact on welfare policy; and ethical implications. This analysis is guided by Foucaults concept of veridiction and understanding of power. This thesis concludes that nudging would be more acceptable if it clarified that humans, in these models, are treated as defective econs. Choice architects are trying to represent the complex reality of hu- man judgment and decision-making with the inclusion of psychology in a highly simplified normative modeling framework, to increase individuals tendency to act according to neo- classical rational choice models.

Rüth and Camilla Simon February 2020 How Do Income and the Debt Position of Households Propagate Public into Private Spending? Sebastian K. R¨uth Camilla Simon∗ February 21, 2020 Abstract We study the household sector's post-tax income and debt position as prop- agation mechanisms of public into private spending, in postwar U.S. data. In structural VARs, we obtain the consumption \crowding-in puzzle" for surges in public spending and show this consumption response to be accompanied by a persistent increase in disposable income. Endogenously reacting income, however, is insufficient to rationalize conditional comovement of private and public spending: once we hypothetically force (dis)aggregate measures of in- come to their pre-shock paths, consumption still rises. Corroborating these findings within an external-instruments-identified VAR, which constitutes an adequate laboratory for the simultaneous interplay of financial and macroe- conomic time-series, we provide causal evidence of fiscal stimulus prompting households to take on more credit. This favorable debt cycle is paralleled by dropping interest rates, narrowing credit spreads, and inflating collat- eral prices, e.g., real estate prices, suggesting that softening borrowing con- straints support the accumulation of debt and help rationalizing the absence of crowding-out.

The recent game-theoretic literature on macroeconomic policy has set the stage for going beyond this stylized description of policymaking and building more realistic positive models of economic policy. In this literature, the policy- maker strategically interacts with other current and/or future policymakers and with the public; his behavior is derived endogenously from his preferences, incentives and constraints. Since the policymakers' incentives and constraints represent real world political institutions, this approach provides a useful tool for analyzing the relationship between politics and macroeconomic policy. This paper shows that this recent line of research has provided several novel, testable results; the paper both reviews previous successful tests of the theory and presents some new successful tests. Even though some pathbreaking contributions were published in the mid-1970s, (for instance, Hamada (1976), Kydland-Prescott (1977), Calvo (1978)) the game-theoretic literature on macroeconomic policy has only in the last five years begun to pick up momentum after a shift attributed to the influential work done by Barro and Gordon (1983a,b) on monetary policy.

    In Search of Lost Time: the Neoclassical Synthesis M. De Vroey and P. Garcia Duarte Discussion Paper 2012-26 IN SEARCH OF LOST TIME: THE NEOCLASSICAL SYNTHESIS Michel De Vroey and Pedro Garcia Duarte ◊ Abstract Present-day macroeconomics has sometimes been dubbed ‘the new neoclassical synthesis’, suggesting that it constitutes a reincarnation of the neoclassical synthesis of the 1950s. This paper assesses this understanding. To this end, we examine the contents of the ‘old’ and the ‘new’ neoclassical syntheses. We show that the neoclassical synthesis originally had no fixed content, but two meanings gradually became dominant. First, it designates the program of integrating Keynesian and Walrasian theory. Second, it designates the methodological principle that in macroeconomics it is better to have alternative models geared towards different purposes than a hegemonic general equilibrium model. The paper documents that: (a) the first program was never achieved; (b) Lucas’s criticisms of Keynesian macroeconomics eventually caused the neoclassical synthesis program to vanish from the scene; (c) the rise of DSGE macroeconomics marked the end of the neoclassical synthesis mark II; and (d) contrary to present-day understanding, the link between the old and the new synthesis is at best weak.

  • The Macroeconomics of Low Inflation

    The Macroeconomics of Low Inflation

    GEORGE A. AKERLOF Brookings Institutionand Universityof California, Berkeley WILLIAM T. DICKENS Brookings Institution GEORGE L. PERRY Brookings Institution The Macroeconomics of Low Inflation THE CONCEPT of a natural unemployment rate has been central to most modern models of inflation and stabilization. According to these models, inflation will accelerate or decelerate depending on whether unemployment is below or above the natural rate, while any existing rate of inflation will continue if unemployment is at the natural rate. The natural rate is thus the minimum, and only, sustainable rate of unemployment, but the inflation rate is left as a choice variable for policymakers. Since complete price stability has attractive features, many economists and policymakers who accept the natural rate hypoth- esis believe that central banks should target zero inflation. We question the standard version of the natural rate model and each of these implications. Central to our analysis is the effect of downward nominal wage rigidity in an economy in which individual firms expe- rience stochastic shocks in the demand for their output. We embed these features in a model that otherwise resembles a standard natural rate model and show there is no unique natural unemployment rate. Rather, the rate of unemployment that is consistent with steady inflation We would especially like to thankNeil Siegel, JustinSmith, andJennifer Eichberger for invaluableresearch assistance.

  • The Macroeconomic Implications of Consumption: State-Of-Art and Prospects for the Heterodox Future Research

    The Macroeconomic Implications of Consumption: State-Of-Art and Prospects for the Heterodox Future Research

    The macroeconomic implications of consumption: state-of-art and prospects for the heterodox future research Lídia Brochier1 and Antonio Carlos Macedo e Silva2 Abstract The recent US economic scenario has motivated a series of heterodox papers concerned with household indebtedness and consumption. Though discussing autonomous consumption, most of the theoretical papers rely on private investment-led growth models. An alternative approach is the so-called Sraffian supermultipler model, which treats long-run investment as induced, allowing for the possibility that other final demand components – including consumption – may lead long-run growth. We suggest that the dialogue between these approaches is not only possible but may prove to be quite fruitful. Keywords: Consumption, household debt, growth theories, autonomous expenditure. JEL classification: B59, E12, E21. 1 PhD Student, University of Campinas (UNICAMP), São Paulo, Brazil. [email protected] 2 Professor at University of Campinas (UNICAMP), São Paulo, Brazil. [email protected] 1 1 Introduction Following Keynes’ famous dictum on investment as the “causa causans” of output and employment levels, macroeconomic literature has tended to depict personal consumption as a well-behaved and rather uninteresting aggregate demand component.3 To be sure, consumption is much less volatile than investment. Does it really mean it is less important? For many Keynesian economists, the answer is – or at least was, until recently – probably positive. At any rate, the American experience has at least demonstrated that consumption is important, and not only because it usually represents more than 60% of GDP. After all, in the U.S., the very ratio between consumption and GDP has been increasing since the 1980s, in spite of the stagnant real labor income and the growing income inequality.
  • Macro Model Objectives : Understand the Difference Between Desired

    Macro Model Objectives : Understand the Difference Between Desired

    Macro Model Objectives : Understand the difference between desired expenditure and actual expenditure. Explain the determinants of desired consumption and desired investment expeditures. Understand the meaning of equilibrium national income. Recognize the difference between movements along and shifts of the aggregate expenditure functions. Desired expenditure Everyone makes expenditure decisions. Fortunately, it is unnecessary for our purposes to look at each of the millions of such individual decisions. Instead, it is sufficient to consider four main groups of decision makers. The sum of their desired expenditures on domestically produced output is called desired aggregate expenditure, or more simply aggregate expenditure (AE). AE = C + I +G +(X-M) Autonomus versus induced expenditure. Components of aggregate expenditure that do not depend on national income are called autonomous expenditures. Components of aggregate expenditure that do change in response to changes in national income are called induced expenditures. Global Economics : macro model 2 Important simplifications Our goal is to develop the simplest possible model of national-income determination. To do so we focus on only two of the four components of desired aggregate expenditure. Consumption and investment Desired consumption expenditure By definition, there are only two possible uses of disposable income–consumption and saving. W hen the household decides how much to put to one use, it has automatically decided how much to put to the other use. The consumption function relates to total desired consumption expenditures of all households. The consumption behaviour of households depends on the income that they actually have to spend, which is called disposable income. Under the assumptions, here, there are no governments, therefore no taxes.
