Abstract:
This paper introduces the Knightian Uncertainty Hypothesis (KUH), a new approach to macroeconomics and finance theory. KUH rests on a novel mathematical framework that characterizes both measurable and Knightian uncertainty about economic outcomes. Relying on this framework and John Muth’s pathbreaking hypothesis, KUH represents participants’ forecasts to be consistent with both uncertainties. KUH thus enables models of aggregate outcomes that 1) are premised on market participants’ rationality, and 2) yet accord a role to both fundamental and psychological (and other non-fundamental) factors in driving outcomes. The paper also suggests how a KUH model’s quantitative predictions can be confronted with time-series data.

Content Type:
Policy Brief
Institution:
Economics for Inclusive Prosperity (EfIP)
Abstract:
During the past 40 years, the United States has experienced a sharp and sustained rise in wage and income inequality. The high level of inequality in the United States reflects both a disconnect between (1) average wages and productivity, and (2) top and bottom wages.

13. Towards a More Inclusive Globalization: An Anti-Social Dumping Scheme

Policy Brief
Institution:
Economics for Inclusive Prosperity (EfIP)
Abstract:
Theory and empirics both suggest that international trade has sharp distributional implications. Furthermore, redistribution caused by trade is often viewed by the general public as more harmful or disruptive than other domestic market shocks. I discuss conditions under which there may be a legitimate case for restricting trade to promote domestic social inclusion, and propose a specific policy – a social safeguards clause – targeting those circumstances.

14. Taxing multinational corporations in the 21st century

Policy Brief
Institution:
Economics for Inclusive Prosperity (EfIP)
Abstract:
Globalization and the rise of intangible capital have increased tax avoidance opportunities for large firms dramatically. 40% of multinational profits are shifted to tax havens each year globally and the United States loses about 15% of its corporate income tax revenue because of this shifting. I discuss the evidence on the redistributive effects of international tax competition. I then present a proposal to reform the corporate tax that would remove any incentive for firms to shift profits or move real activity to lowtax places. Contrary to a widespread view, it is possible to tax multinational companies (potentially at high rates) in a globalized world, even in the absence of international policy coordination.

15. Missing from the Mainstream: The Biophysical Basis of Production and the Public Economy

Author:
June Sekera
Publication Date:

Content Type:
Working Paper
Institution:
Global Development and Environment Institute at Tufts University
Abstract:
Just as mainstream economics neglects the biophysical basis of production and disregards energy as the most fundamental input, it likewise ignores the existence of the public economy. Both types of denialism threaten the ability of societies to develop energy solutions that can meet the needs of the polity. This article calls for a new theory of the public economy and it outlines elements of such a theory. Both a biophysical economics and a new public economics are needed to address the energy challenges confronting modern societies.

16. Explaining the Prevalence, Scaling and Variance of Urban Phenomena

Abstract:
The prevalence of many urban phenomena changes systematically with population size1. We propose a theory that unifies models of economic complexity2, 3 and cultural evolution4 to derive urban scaling. The theory accounts for the difference in scaling exponents and average prevalence across phenomena, as well as the difference in the variance within phenomena across cities of similar size. The central ideas are that a number of necessary complementary factors must be simultaneously present for a phenomenon to occur, and that the diversity of factors is logarithmically related to population size. The model reveals that phenomena that require more factors will be less prevalent, scale more superlinearly and show larger variance across cities of similar size. The theory applies to data on education, employment, innovation, disease and crime, and it entails the ability to predict the prevalence of a phenomenon across cities, given information about the prevalence in a single city.

17. A Note on Credit Allocation, Income Distribution, and the Circuit of Capital (pdf)

Author:
Paulo dos Santos
Publication Date:

Content Type:
Working Paper

Abstract:
This note considers the relationship between credit allocation and the aggregate, class distribution of income in the Circuit of Capital. Production and consumption credit inject means of purchase in different locations in the monetary circuits of capitalist reproduction. On the basis of comparative-dynamic analysis of the properties of steady-state evolutions, the note shows that production credit increases the wage share in total income, while consumption credit increases profit shares. These findings hold in general for any evolution in which sectoral revenue- elasticities of outlays measure less than unity. The note also motivates a new endogenous approach to the aggregate distribution of income, and offers new analytical tools facilitating work based on demand-constrained models of the Circuit of Capital.

18. A History of Polyvalent Structural Parameters: the Case of Instrument Variable Estimato

Author:

Publication Date:

Content Type:
Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
This paper investigates the rise and fall of the IV method in macro-econometric models and its subsequent revival in micro-econometric models. The key findings are: (i) the IV method implicitly breaks the contemporaneously circular causality postulated in a simultaneous- equation model (SEM) by redefining the conditional variable concerned as a suboptimal conditional expectation of it; (ii) the IV method falls out of favour in macro-econometrics mainly because of lack of empirical validations for such redefinitions; (iii) the IV method wins its popularity in micro-econometrics by its capacity to produce multiple suboptimal conditional expectations of the latent conditional variables of interest under the disguise of an SEM consistent estimator; nevertheless, (iv) such suboptimal conditional expectations give rise to the insurmountable difficulty of credibly interpreting the IV-based parameter estimates, especially in the case of prognosticated omitted variable bias. The findings highlight the methodological drawback of the estimator-centric strategy of textbook econometrics.

19. Modelling Scale Effect in Crosssection Data:The Case of Hedonic Price Regression

Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
An innovative and simple experiment with cross-section data ordering is carried out to exploit a basic and common feature between many economic variables – nonlinear scale dependence. The experiment is tried on hedonic price regression models using two data sets, one for automobiles and the other computers. The key findings are: (a) Hedonic price indices can be significantly biased if they are constructed using models which disregard possible nonlinear scale effects latent in random data samples; (b) Scale-based data ordering offers considerable potential to filter such scale-dependent information from cross-section samples; (c) The filtering can be easily carried out by systematic adoption of dynamic modelling methods.

20. Capital Flows to Emerging Markets: An alternative Theoretical Framework

Author:
Bruno Bonizzi

School of Oriental and African Studies - University of London
Abstract:
This paper represents a theoretical contribution to the analysis of international capital flows. It outlines an alternative theoretical framework based on Post-Keynesian monetary theory, and in particular on Hyman Minsky’s Wall Street paradigm and concept of Money-manager capitalism and Jan Toporowski’s theory of capital market inflation. The key aspects of such an approach are, firstly, that in a monetary analysis capital flows need to be understood as “flows of funds”, as opposed to the traditional understanding of capital flows based on “real” decision, such as saving and investment. A consequence of this is the need of focusing on gross rather than net capital flows. Secondly, when considering emerging markets, the asymmetric nature of the international monetary system must be stressed. Thirdly, it is important to understand the specific forms that capital flows take: in today’s world, pension funds and other institutional investors — alongside banks — are key players in the financial markets, and their role in shaping capital flows to emerging markets must be explicitly recognised. This paper synthesises these elements by understanding capital flows as the result of institutional investors portfolio choice. Along the lines of Minsky and Toporowski, portfolio choice by institutional investors need to be assessed in relation to their balance sheet structure, beside risk/return trade-offs and general state of risk aversion
