2. Why Diagnostic Expectations Cannot Replace REH

Institution:
Institute for New Economic Thinking (INET)
Abstract:
Gennaioli and Shleifer (GS) have proposed diagnostic expectations (DE) as an empirically-based approach to specifying participants’ expectations, which, like REH, can be applied in every model. Beyond its supposedly general applicability, GS’s formalization of DE implies that participants systematically and predictably overreact to news. Here, we present a formal argument that Kahneman and Tversky’s compelling empirical findings, and those of other behavioral economists, do not provide a basis for a general approach to specifying participants’ “predictable errors.” We also show that the overreaction of participants’ expectations is not a regularity, but rather an artifact of GS’s particular specification of DE.

Abstract:
Thus far in reporting the findings of our project “Fifty Years After: Black Employment in the United States Under the Equal Employment Opportunity Commission,” our analysis of what has happened to African American employment over the past half century has documented the importance of manufacturing employment to the upward socioeconomic mobility of Blacks in the 1960s and 1970s and the devastating impact of rationalization—the permanent elimination of blue-collar employment—on their socioeconomic mobility in the 1980s and beyond. The upward mobility of Blacks in the earlier decades was based on the Old Economy business model (OEBM) with its characteristic “career-with-one-company” (CWOC) employment relations. At its launching in 1965, the policy approach of the Equal Employment Opportunity Commission assumed the existence of CWOC, providing corporate employees, Blacks included, with a potential path for upward socioeconomic mobility over the course of their working lives by gaining access to productive opportunities and higher pay through stable employment within companies. It was through these internal employment structures that Blacks could potentially overcome barriers to the long legacy of job and pay discrimination

5. Land Grabbing and International Political Economy: Towards a Critical Neo-Gramscian Theoretical Model of Land Governance in Latin America

Abstract:
The vigorous debate on global land grabbing within Critical Agrarian Studies contrasts with the incipient analyses from International Political Economy (IPE). This divergence has overshadowed the multi-scalar nature of the power relations that shape land governance, and consequently its effects on land grabbing. For this reason, this paper provides a critical theoretical model of land governance based on Robert Cox’s historical structures approach to understand the causes of land grabbing in Latin American countries. It is argued that this model renders visible the articulation of local and global processes driving land grabbing because it foregrounds the power relations at multiple scales that shape decisions on land access, use and control, as well as the conflicts inherent to them. This demonstrates that, on the one hand, land governance structures in Latin America play a hegemonic role since they express and develop the global agricultural model that promotes land grabbing. On the other hand, social resistance highlights that land governance simultaneously possesses a potential for change. As a result, knowledge about land grabbing is enhanced through a dialogue between the two fields of study.

6. Tracing the evolution of service robotics: Insights from a topic modeling approach

Kiel Institute for the World Economy (IfW)
Abstract:
Taking robotic patents between 1977 and 2017 and building upon the topic modeling technique, we extract their latent topics, analyze how important these topics are over time, and how they are related to each other looking at how often they are recombined in the same patents. This allows us to differentiate between more and less important technological trends in robotics based on their stage of diffusion and position in the space of knowledge, where some topics appear isolated while others are highly interconnected. Furthermore, we propose a novel approach to match the constructed topics to the IFR classification of service robots based on frequency and exclusivity of words overlapping between them. We identify around 20 topics belonging to service robotics. Our results corroborate earlier findings, but also provide novel insights on the content and stage of development of application areas in service robotics. With this study we contribute to a better understanding of the highly dynamic field of robotics and contribute to new practices of utilizing the topic modeling approach.

7. Cordon of Conformity: Why DSGE models Are Not the Future of Macroeconomics

Institution:
Institute for New Economic Thinking (INET)
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.

8. Ambivalence About International Trade in Open- and Closed-ended Survey Responses

Abstract:
Spontaneous, open-ended survey responses can sometimes better reveal what is actually on people’s minds than small sets of forced-choice, closed questions. Our analysis of closed questions and trade-related open-ended responses to 2016 ANES “likes” and “dislikes” prompts indicate that Americans held considerably more complex, more ambivalent, and – in many cases – more negative views of international trade than has been apparent in studies that focus only on closed-ended responses. This paper suggests that contrast between open- and closed-question data may help explain why the effectiveness of Donald Trump’s appeals to trade resentments surprised many observers.

9. Asset Prices Under Knightian Uncertainty

Institution:
Institute for New Economic Thinking (INET)
Abstract:
We extend Lucas’s classic asset-price model by opening the stochastic process driving dividends to Knightian uncertainty arising from unforeseeable change. Implementing Muth’s hypothesis, we represent participants’ expectations as being consistent with our model’s predictions and formalize their ambiguity- averse decisions with maximization of intertemporal multiple-priors utility. We characterize the asset-price function with a stochastic Euler equation and derive a novel prediction that the relationship between prices and dividends undergoes unforeseeable change. Our approach accords participants’ expectations, driven by both fundamental and psychological factors, an autonomous role in driving the asset price over time, without presuming that participants are irrational.
