The Unassuming Economist

From a paper by James Galbraith, Ravi Kanbur, Kunal Sen, and Andy Sumner:

“Seven decades ago, Simon Kuznets put forward the hypothesis that as economies developed, national inequality would first increase and then decrease—an inverted U-shape. He provided preliminary evidence for the hypothesis on the basis of the limited data available at the time, and theorized the genesis of the curve as arising from the twin forces of structural transformation of the economy and political economy pressures. Seven decades on, the Kuznets curve still has a hold on the development discourse as new data is used to test the hypothesis, new theories are elaborated to explain the evolution of inequality, and the metaphor of an inverse U-shape is extended beyond its original realm of national inequality. With this rich history and background, the time is right to examine the Kuznets curve literature broadly construed. This overview takes stock of what has been learned and highlights emerging research and policy questions.”

From a book edited by Ulrich Mückenberger, Heiner Fechner, and Irene Dingeldey:

“The volume Constructing Worlds of Labour aims to break new ground in presenting results on different types of labour standards around the world as regulatory social policy. The specifc topic is to make visible that, and to explain why, employment law worldwide not only has a protective role but also a segmenting role—creating social differentiation based on status, gender and/or race. We conceptualised this role of law as legal segmentation and identifed various historical and power-related reasons for it. We also want to identify how segmenting employment law interacts with segmentative implications of other (current and/or historical) legal institutions—such as social law, family law, tax law, but also legislation based on slavery, gender, race and ethnicity. As explanations, not only path dependent institutional developments are the subject of in-depth investigations but also colonial infuences, international organisations and
epistemic communities including postcolonial thought. The research outcomes are comprehensively discussed in order to derive propositions on how to overcome the described situation in the different worlds of labour. Hence, not only applying a global perspective but also treading new paths in interdisciplinary co-operation—both theoretically/normatively and empirically—makes this book outstanding.”

From a paper by Panagiotis E. Petrakis, Giorgos Vasilis, and Anna-Maria Kanzola:

“This chapter explores major economic megatrends shaping the global economy, focusing on three transformative forces: persistent economic inequality, the rising global debt, and the shift in global economic power from the West to the East and South. It examines how historical developments, technological progress, globalization, and crises such as the 2008 financial collapse and the Covid-19 pandemic have contributed to growing inequalities. The chapter also analyzes the continuous increase in global debt, highlighting its implications for financial stability and long-term growth. Lastly, it discusses the rebalancing of global economic power, emphasizing the roles of emerging economies, particularly in Asia, and the challenges posed by a multipolar world. These trends are framed as critical for understanding the future trajectory of global economic and political dynamics.”

From a post by by Jay Kulkarni and Susan Thomas:

The economic well-being of households is primarily about their ability to spend on consumption. Household consumption is dominated by what the income of the household is, but not limited by it. Households that spend less than they earn, build their savings. Households that spend more than they earn either borrow or draw down on earlier savings. There is a big difference in the life-cycle possibilities between households that manage to save versus those that do not. In this article, we analyse a panel dataset of Indian households to understand what differentiates households who live within, or beyond, their means.

An often discussed measure of the household’s income-consumption dynamic is the `marginal propensity to consume’ or MPC, which is the marginal change in consumption for a marginal change in income. The MPC is a valuable part of the toolkit of macroeconomics. An equally important measure is the ‘average propensity to consume’ (which is abbreviated as APC). This is the fraction of disposable income that the household consumes. The APC shows the income-consumption dynamics of a household in a stated time period. When the APC is below 1, the household is saving, and on average, building up its wealth. There is a clear line between low APC households (i.e. those with APC below 1), who are building up wealth, vs. the households that are not.

In an advanced economy, we think of the APC as a part of life cycle optimisations. When an affluent and financial unconstrained household is young, it builds up savings (i.e. low APC), and then it dis-saves in old age (i.e. high APC). In a poor country, we see many households who are dis-saving even when they are young. Building up wealth versus drawing down wealth takes on a different character in the context of a low middle income economy (Badarinza et al, 2019).

Aggregate facts about household APC, and its covariates, are an important element of understanding India. This article aims to establish such facts. What is the average household APC in India? What fraction of households have a low APC? Do higher income households have a low APC? Do low APC households have lower income volatility? Are low APC households systematically older households? What is the connection between financial inclusion and household APC?”

From a paper by Yu Yang, Qi Zhang, A-Min Zhao, and Hui Gao:

“This study investigates whether China’s Emissions Trading System (ETS) can simultaneously achieve carbon emission reductions and economic growth—a dual objective often described as “having the best of both worlds.” Utilizing panel data from 2508 counties spanning 2000 to 2020, we treat the implementation of the ETS as a quasi-natural experiment and employ a staggered difference-in-differences (DID) approach to evaluate its effects. The results show that the ETS significantly reduces carbon emissions while promoting industry output, confirming the compatibility of environmental and economic objectives. Robustness checks confirm the stability of the estimates. Mechanism analyses reveal that the policy’s success is primarily driven by technological innovation and enhanced environmental regulation. Heterogeneity analyses indicate that the ETS’s effectiveness is more pronounced in cities with stronger industrial foundations, higher enforcement capacity, and those located in the Yangtze River Basin. This research contributes to the environmental economics literature by offering evidence at the county level and provides actionable policy insights for the design and regional tailoring of market-based environmental regulation tools.”
