Experts are gaining a direct view of the economy’s core dynamics, uncovering not only the scale of growth but also who truly benefits from it. This American initiative provides policymakers with powerful tools to track and respond to disparities in real time, introducing a groundbreaking innovation that redefines how the economic landscape is understood.
The economy is a vast and intricate tapestry of endless threads, each representing a distinct facet of our collective existence: individuals striving to earn a living, companies innovating to stay ahead, governments formulating policies to guide their nations, and interconnected global markets.
The true understanding of the economy, then, lies in deciphering the patterns within this fabric, comprehending the forces that drive growth, the inequalities that arise among population groups, and the societal ramifications that unfold.
Since the 1930s, the concept of Gross Domestic Product (GDP) has been the cornerstone of economic measurement and the primary, most reliable means of assessing national income and guiding policies. It has shaped markets, policies, and international relations. However, it suffers from a significant structural flaw: it fails to measure individuals' shares of their countries' income. It has proven to be an inadequate, and perhaps misleading, tool for understanding wealth distribution across different socioeconomic groups. This means we can read figures explaining the extent of economic growth, but the beneficiaries of this growth, as well as the nature and fairness of that benefit, remain unknown.
This gap in understanding has profound implications, intensifying during periods of economic contraction or recovery. Often, one group suffers more than others in the former scenario or receives only meager benefits in the latter.
Seeking a new approach, a group of economic researchers at the University of California, Berkeley, and the James M. and Cathleen D. Stone Center on Wealth and Income Inequality stepped in.
The experts developed an innovative tool called "Real-Time Inequality" to provide a more rapid, accurate, and detailed understanding of economic performance across different income groups, such as the working class and the middle class.
This tool utilizes high-frequency public data to track the distribution of income and wealth periodically. It gathers figures and statistics every three months and compares them to previous data to build real-time insights into these economic indicators.
Income is classified into four types: factor income (labor and capital income before taxes), pre-tax income (adjusted for benefits and contributions), disposable income (net of taxes and transfers), and post-tax income (including non-cash transfers and public spending). Wealth includes all financial and non-financial assets, excluding unfunded pensions and vehicles.
The analysis considers three population groups: adult individuals (20 years and older), working-age adults (20-64 years), and households. Data is collected from public sources such as employment surveys, national accounts, and wage censuses. This process generates monthly microfiles, where income and wealth variables are assigned to individuals in accordance with national accounts and observed data distributions.
For instance, the tool revealed stark disparities in recovery rates among different income groups during previous recessions. Following the Great Depression, GDP recovered within four years, but the bottom 50% of Americans needed an additional six years to regain their pre-crisis income levels.
In contrast, after the economic recession caused by the COVID-19 pandemic, the bottom 50% of the income distribution recovered within just one year and eight months, benefiting from a tight labor market and unprecedented government benefits.
In the first quarter of 2023, the tool showed that the bottom 50% experienced a 1.5% increase in real income, while the top 1% recorded a 4.3% increase, indicating that the income gap continues to widen.
One of the main challenges in developing this tool was the integration and aggregation of data from various official sources, especially given the large and extensive databases held by the US government on inequality. However, updating this data often takes one to two years, hindering proper analysis and timely policy responses. Consequently, the team had to overcome these technical and logistical obstacles to harmonize diverse data sources and generate accurate and up-to-date insights.
On another front, the project faced the challenge of building the methodology. It had to be robust and aligned with macroeconomic growth statistics; otherwise, it would lack relevance and yield inapplicable results. This also necessitated obtaining specific estimates for diverse socioeconomic groups.
Notably, the tool has had a profound impact on economic work, enabling policymakers to analyze reality and allocate resources effectively and based on data.
The researchers hope that their prototype will be applied at the federal and then global levels, where other countries can adopt it to enhance transparency in their operations. The economy, after all, is a set of codes, and by deciphering them, we gain the ability to predict and adapt, ultimately building a more balanced and equitable economic landscape.
