Abstract:
The Rebuilding Macroeconomic Theory Project, led by David Vines and Samuel Wills (2020), is an important, albeit long overdue, initiative to rethink a failing mainstream macroeconomics. Professors Vines and Wills, who must be congratulated for stepping up to the challenge of trying to make mainstream macroeconomics relevant again, call for a new multiple-equilibrium and diverse (MEADE) paradigm for macroeconomics. Their idea is to start with simple models, ideally two-dimensional sketches, that explain mechanisms that can cause multiple equilibria. These mechanisms should then be incorporated into larger DSGE models in a new, multiple-equilibrium synthesis – to see how the fundamental pieces of the economy fit together, subject to it being ‘properly micro-founded’. This paper argues that the MEADE paradigm is bound to fail, because it maintains the DSGE model as the unifying framework at the center of macroeconomic analysis. The paper reviews 10 fundamental weaknesses inherent in DSGE models which make these models irreparably useless for macroeconomic policy analysis. Mainstream macroeconomics must put DSGE models, once and for all, in the Museum of Implausible Economic Models – and learn important lessons from non-DSGE macroeconomic approaches.

2. The Economics and Politics of Social Democracy: A Reconsideration

Abstract:
Questions about the decline of Social democracy continue to excite wide interest, even in the era of Covid-19. This paper takes a fresh look at topic. It argues that social democratic politics faces a fundamental dilemma: short-term practical relevance requires it to accept, at least partly, the very socio-economic conditions which it purports to change in the longer run. Bhaduri’s (1993) essay which analyzes social democracy’s attempts to navigate this dilemma by means of ‘a nationalization of consumption’ and Keynesian demand management, was written before the rise of New (‘Third Way’) Labor and before the Great Financial Crisis of 2007-8. This paper provides an update, arguing that New Labor’s attempt to rescue ‘welfare capitalism’ entailed a new solution to the dilemma facing social democracy based on an expansion of employment, i.e. an all-out emphasis on “jobs, jobs, jobs”. The flip-side (or social cost) of the emphasis on job growth has been a stagnation of productivity growth—which, in turn, has put the ‘welfare state’ under increasing pressure of fiscal austerity. The popular discontent and rise of ‘populist’ political parties is closely related to the failure of New Labor to navigate social democracy’s dilemma.

3. The Secular Stagnation of Productivity Growth

Abstract:
The concern that an economy could experience persistent stagnation, caused by a structural weakness of aggregate demand, goes back to Alvin Hansen’s (1939) thesis of ‘secular stagnation’. Hansen’s thesis has been revived in recent times, when it became clear that productivity and potential growth in the OECD countries have been declining for decades. However, in line with deep-rooted theoretical beliefs, that inadequate demand can only affect growth in the short run, secular stagnation (of potential growth) is treated as an exclusively supply-side problem, the root of which is a worrying steady decline in productivity growth. This paper argues that it is a mistake to dismiss secular demand stagnation as main cause of declining potential growth in the OECD. We argue that the theoretical case for demand-caused secular stagnation is strong and empirical evidence that it has affected the U.S. economy after the mid-1970s is entirely convincing. Demand is leading supply, also in the long run. Hansen had it right, after all.

4. Economic Growth and Carbon Emissions: The Road to ‘Hothouse Earth’ is Paved with Good Intentions

Abstract:
All IPCC (2018) pathways to restrict future global warming to 1.5°C (and well below an already dangerous 2°C) involve radical cuts in global carbon emissions. Such decarbonization, while being technically feasible, may impose a ‘limit’ or ‘planetary boundary’ to growth, depending on whether or not human society can decouple economic growth from carbon emissions. Decoupling is regarded viable in global and national policy discourses on the Paris Agreement—and claimed to be already happening in real time: witness the recent declines in territorial CO2 emissions in a group of more than 20 economies. However, some scholars argue that radical de-carbonization will not be possible while increasing the size of the economy. This paper contributes to this debate as well as to the larger literature on climate change and sustainability. First, we develop a prognosis of climate-constrained global growth for 2014-2050 using the Kaya sum rule. Second, we use the Carbon-Kuznets-Curve (CKC) framework to empirically assess the effect of economic growth on CO2 emissions using measures of both territorial (production-based) emissions and consumption-based (tradeadjusted) emissions. We run panel data regressions using OECD ICIO CO2 emissions data for 61 countries during 1995-2011; to check the robustness of our findings we construct and use panel samples sourced from alternative databases (Eora; Exio; and WIOD). Even if we find evidence suggesting a decoupling of production-based CO2 emissions and growth, consumption-based CO2 emissions are monotonically increasing with per capita GDP (within our sample). We draw out the implications of these findings for climate policy and binding emission reduction obligations.

5. The New Normal: Demand, Secular Stagnation and the Vanishing Middle-Class

Abstract:
The U.S. economy is widely diagnosed with two ‘diseases’: a secular stagnation of potential U.S. growth, and rising income and job polarization. The two diseases have a common root in the demand shortfall, originating from the ‘unbalanced’ growth between technologically ‘dynamic’ and ‘stagnant’ sectors. To understand how the short-run demand shortfall carries over into the long run, this paper first deconstructs the notion of total-factor-productivity (TFP) growth, the main constituent of potential output growth and “the best available measure of the underlying pace of exogenous innovation and technological change”. The paper argues that there is no such thing as a Solow residual and demonstrates that TFP growth can only be meaningfully interpreted in terms of labor productivity growth. Because labor productivity growth, in turn, is influenced by demand factors, the causes of secular stagnation must lie in inadequate demand. Inadequate demand, in turn, is the result of a growing segmentation of the U.S. economy into a ‘dynamic’ sector which is shedding jobs, and a ‘stagnant’ and ‘survivalist’ sector which acts as an ‘employer of last resort’. The argument is illustrated with long-run growth-accounting data for the U.S. economy (1948-2015). The mechanics of dualistic growth are highlighted using a Baumol-inspired model of unbalanced growth. Using this model, it is shown that the ‘output gap’, the anchor of monetary policy, is itself a moving target. As long as this endogeneity of the policy target is not understood, monetary policymakers will continue to contribute to unbalanced growth and premature stagnation.

Working Paper Carbon Emissions and Economic Growth: Production-based versus Consumption-based Evidence on Decoupling MAR 2016 | ENERGY | ENVIRONMENT SHARE WORKING PAPER SERIES BY Goher-Ur-Rehman Mir Ecofys Consulting Servaas Storm Senior Lecturer of Economics, Delft University of Technology DOWNLOAD PAPER We assess the Carbon-Kuznets-Curve hypothesis using internationally consistent and comparable production-based versus consumption-based CO2 emissions data for 40 countries (and 35 industries) during 1995-2007 from the World Input Output Database (WIOD). The estimates for per capita CO2 emissions are truly comprehensive as these include all carbon emissions embodied in international trade and global commodity chains. Even if we find evidence suggesting a decoupling of production-based CO2 emissions and growth, consumption- based CO2 emissions are monotonically increasing with per capita GDP. We draw out the implications of these findings for climate policy and binding emission reduction obligations.
