421. Debt Servicing, Aggregate Consumption, and Growth

Institute for New Economic Thinking (INET)
Abstract:
We develop a neo-Kaleckian growth model that emphasizes the importance of consumption behavior. In our model, workers first make consumption decisions based on their gross income, and then treat debt servicing commitments as a substitute for saving. Workers’ borrowing is induced by their desire to keep up with the consumption standard set by rentiers’ consumption, reflecting an aspect of the relative income hypothesis. As a result of this consumption and debt servicing behavior, consumer debt accumulation and income distribution have effects on aggregate demand, profitability, and economic growth that differ from those found in existing models. We also investigate the financial sustainability of the Golden Age and Neoliberal growth regimes within our framework. It is shown that distributional changes between the Golden Age and the Neoliberal regimes, together with corresponding changes in consumption emulation behavior via expenditure cascades, suffice to make the Neoliberal growth regime unsustainable.

422. Working Paper Exploring the Concept of Homeostasis and Considering its Implications for Economics

Abstract:
The reality of human homeostasis expands the views on preferences and rational choice that are part of traditionally conceived Homo economicus and casts doubts on economic models that depend only on an “invisible hand” mechanism. In its standard format, the concept of homeostasis refers to the ability, present in all living organisms, of continuously maintaining certain functional variables within a range of values compatible with survival. The mechanisms of homeostasis were originally conceived as strictly automatic and as pertaining only to the state of an organism’s internal environment. In keeping with this concept, homeostasis was, and still is, often explained by analogy to a thermostat: upon reaching a previously set temperature, the device commands itself to either suspend the ongoing operation (cooling or heating), or to initiate it, as appropriate. This traditional explanation fails to capture the richness of the concept and the range of circumstances in which it can be applied to living systems. Our goal here is to consider a more comprehensive view of homeostasis. This includes its application to systems in which the presence of conscious and deliberative minds, individually and in social groups, permits the creation of supplementary regulatory mechanisms aimed at achieving balanced and thus survivable life states but more prone to failure than the fully automated mechanisms. We suggest that an economy is an example of one such regulatory mechanism, and that facts regarding human homeostasis may be of value in the study of economic problems. Importantly, the reality of human homeostasis expands the views on preferences and rational choice that are part of traditionally conceived Homo economicus and casts doubts on economic models that depend only on an “invisible hand” mechanism.

423. Are Low Interest Rates Deflationary? A Paradox of Perfect- Foresight Analysis

Author:
Mariana Garcia-Schmidt

Abstract:
A prolonged period of extremely low nominal interest rates has not resulted in high inflation. This has led to increased interest in the “Neo-Fisherian” proposition according to which low nominal interest rates may themselves cause inflation to be lower. The fact that standard models of the effects of monetary policy have the property that perfect foresight equilibria in which the nominal interest rate remains low forever necessarily involve low inflation (at least eventually) might seem to support such a view. Here, however, we argue that such a conclusion depends on a misunderstanding of the circumstances under which it makes sense to predict the effects of a monetary policy commitment by calculating the perfect foresight equilibrium consistent with the policy. We propose an explicit cognitive process by which agents may form their expectations of future endogenous variables. Under some circumstances, such as a commitment to follow a Taylor rule, a perfect foresight equilibrium (PFE) can arise as a limiting case of our more general concept of reflective equilibrium, when the process of reflection is pursued sufficiently far. But we show that an announced intention to fix the nominal interest rate for a long enough period of time creates a situation in which reflective equilibrium need not resemble any PFE. In our view, this makes PFE predictions not plausible outcomes in the case of policies of the latter sort. According to the alternative approach that we recommend, a commitment to maintain a low nominal interest rate for longer should always be expansionary and inflationary, rather than causing deflation; but the effects of such “forward guidance” are likely, in the case of a long- horizon commitment, to be much less expansionary or inflationary than the usual PFE analysis would imply.

424. Is There a Debt-threshold Effect on Output Growth?

Author:
M. Hashem Pesaran
Publication Date:

Content Type:
Working Paper
Institution:
Institute for New Economic Thinking (INET)
Abstract:
This paper studies the long-run impact of public debt expansion on economic growth and investigates whether the debt-growth relation varies with the level of indebtedness. Our contribution is both theoretical and empirical. On the theoretical side, we develop tests for threshold effects in the context of dynamic heterogeneous panel data models with cross- sectionally dependent errors and illustrate, by means of Monte Carlo experiments, that they perform well in small samples. On the empirical side, using data on a sample of 40 countries (grouped into advanced and developing) over the 1965-2010 period, we find no evidence for a universally applicable threshold effect in the relationship between public debt and economic growth, once we account for the impact of global factors and their spillover effects. Regardless of the threshold, however, we find significant negative long-run effects of public debt build-up on output growth. Provided that public debt is on a downward trajectory, a country with a high level of debt can grow just as fast as its peers.

425. Social Interaction Models and Keynes’ Macroeconomics

Author:
Duncan Foley
Publication Date:

Content Type:
Working Paper
Institution:
Institute for New Economic Thinking (INET)
Abstract:
The central concepts of Keynes’ macroeconomic theories concerning the behavior of labor markets, aggregate demand, and asset pricing can be formulated as special cases of a general social interaction model. In its simplest form this model analyzes a system of interacting identical agents, each of whom controls the level of an action, and all of whom have the same utility functions trading off the effort required by the action with the monetary incentives for it. When the incentives include an interaction term involving the action levels of the other agents, the equilibrium outcome is in general Pareto-inefficient for the interacting agents, and multiple equilibria are possible. The expectations that lie at the heart of Keynes’ conception of macroeconomic equilibrium concern the behavior of other individuals rather than concrete forecasts of the concrete path of prices.

Abstract:
The largely unexpected arrival of the global economic crisis and the largely unpredicted slowness of the recovery from the Great Recession should be precipitating an intellectual crisis across economics and policy making. We require additional theories and additional methods to detect how an economy is evolving and to provide the basis for policy intervention (Haldane, 2014).

428. Board Gender Diversity, Audit Fees and Auditor Choice

Content Type:
Working Paper

Institute for New Economic Thinking (INET)
Abstract:
Using a sample of U.S. firms spanning 2001-2011, we examine whether female directors (female audit committee members) affect audit quality in terms of audit effort and auditor choice. After correcting for endogeneity and other board, firm and industry characteristics, we find that firms with gender-diverse boards pay higher audit fees and are more likely to choose specialist auditors compared to their peers. Our findings suggest that boards with female directors are likely to demand higher audit quality, ceteris paribus.

429. A New Rational Expectations Hypothesis: What Can Economists Really Know About the Future?

Author:
Roman Frydman and Michael Goldberg

Working Paper
Institution:

Abstract:
John Muth proposed the Rational Expectations Hypothesis (REH) to represent how the market (an aggregate of its participants) understands and forecasts outcomes. REH imposes internal consistency between the market’s forecasts and “the relevant economic theory” (Muth 1961, p. 316). In implementing REH, economists have relied on a class of models that rest on a key premise: an economist can ignore the importance of quantitative changes in the economy’s structure that he himself could not specify ex ante with a probabilistic rule. In the early 1970s, Robert Lucas pointed out that once such models are upheld as “the relevant economic theory,” it follows on purely logical grounds that REH models represent rational forecasting and its implications for market outcomes. There is ample evidence that quantitative structural change is an important driver of outcomes in real-world markets, most notably those for assets. The evidence also shows that this change often is triggered by historical events that are not exact repetitions of similar events in the past, for example, the appointment of a new Federal Reserve chair or company CEO. The timing of these events may be unknown, and their quantitative impact on the economy’s structure depends on the extent of their novelty and the particular historical context in which they occur. As such, no one can fully anticipate — even in probabilistic terms — the structural change triggered by such events.

Abstract:
The adoption and diffusion of inputs in the production network is at the heart of technological progress. What determines which inputs are initially considered and eventually adopted by innovators? We examine the evolution of input linkages from a network perspective, starting from a stylized model of network formation. The adoption and diffusion of inputs in the production network is at the heart of technological progress. What determines which inputs are initially considered and eventually adopted by innovators? We examine the evolution of input linkages from a network perspective, starting from a stylized model of network formation. Producers direct their search for new inputs along vertical linkages, screening the network neighborhood of existing suppliers to identify potentially useful inputs. A subset of these is then adopted, following a tradeoff between the benefits from input variety and the costs of customizing new inputs. Guided by this framework, we document a novel stylized fact at both the sector and the firm level: producers are more likely to adopt inputs that are already used – directly or indirectly – by their current suppliers. In particular, using disaggregated input-output data, we show that initial network proximity of a sector in 1967 significantly increases the likelihood of adoption throughout the subsequent four decades. A one-standard deviation decrease in network distance is associated with an increase in the adoption probability by one third to one half. Similarly, U.S. firms are significantly more likely to develop new input linkages among their suppliers’ network neighborhood. Our results imply that the existing production network plays a crucial role in the diffusion of inputs and the evolution of technology.
