Economics need to change - now more than ever! With Exploring Economics, we strengthen alternative economic approaches and counter mainstream economics with a critical and pluralistic vision of economic education. We also provide background analyses on current economic debates to strengthen a critical economic discourse.
Unfortunately, we are running out of money to continue our work.
With a small contribution you can help Exploring Economics to stay online. Thank you!

First some properties about the Sum of squared residuals and the linear regression function are restated. In particular three properties that an ideal fitted regression line must fulfill are discussed. Then, the R squared is defined using the measures of the Sum of squared residuals, the total sum of squares and the sum of explained squares.

The definition of a chi-square distribution is given. Chi-square is defined as the sum of random normally distributed variables (mean=0, variance=s.d.=1). The number of added squared variables is equal to the degrees of freedom. With more degrees of freedom the probability of larger chi-square values is increased.
Chi-square distribution introduction
First some terminology is explained. Then the interpretations of the coefficients and constants of the function are discussed. Afterwards the zero conditional mean assumption regarding the residual is problematized. Lastly, a graphical representation of a regression line is given and the least sum of squared errors is introduced and the equation for the coefficient of the linear function as well as for the intercept is given.

Trickle Down Economics - an old topic, but still present in our lives. The idea consists of deregulation of the economy and of lower tax for the top in order to increase the "size of the pie" so everybody would have a bigger piece, even with a smaller share.
A critique to Trickle-down economics
Stratification economics is defined as a systemic and empirically grounded approach to addressing intergroup inequality. Stratification economics integrates economics, sociology and social psychology to distinctively analyze inequality across groups that are socially differentiated, be it by race, ethnicity, gender, caste, sexuality, religion or any other social differentiation.
Stratification Economics
The notion that the demand and supply side are independent is a key feature of textbook undergraduate economics and of modern macroeconomic models. Economic output is thought to be constrained by the productive capabilities of the economy - the ‘supply-side' - through technology, demographics and capital investment. In the short run a boost in demand may increase GDP and employment due to frictions such as sticky wages, but over the long-term successive rises in demand without corresponding improvements on the supply side can only create inflation as the economy reaches capacity. In this post I will explore the alternative idea of demand-led growth, where an increase in demand can translate into long-run supply side gains. This theory is most commonly associated with post-Keynesian economics, though it has been increasingly recognised in the mainstream literature.
It’s Demand All the Way Down
How did Britain's economy become a bastion of inequality? In this landmark book, the author of The New Enclosure provides a forensic examination and sweeping critique of early-twenty-first-century capitalism. Brett Christophers styles this as 'rentier capitalism', in which ownership of key types of scarce assets--such as land, intellectual property, natural resources, or digital platforms--is all-important and dominated by a few unfathomably wealthy companies and individuals: rentiers.

In parallel to rising inflation numbers, the concept of profit inflation has clearly risen to prominence in recent years. But what is it exactly? This dossier aims not only to collect the most important publications on profit inflation but also intends to map out the development of the discourse and the different positions within the debate.

In the history of the social sciences, few individuals have exerted as much influence as has Jeremy Bentham. His attempt to become “the Newton of morals” has left a marked impression upon the methodology and form of analysis that social sciences like economics and political science have chosen as modus operandi.

The Covid-19 pandemic has laid bare the deep structural rifts in modern capitalist economies. It has exposed and exacerbated the long-lasting systemic inequalities in income, wealth, healthcare, housing, and other aspects of economic success across a variety of dimensions including class, gender, race, regions, and nations. This workshop explores the causes of economic inequality in contemporary capitalist economies and its consequences for the economy and society in the post-pandemic reality, as well as what steps can be taken to alleviate economic inequality in the future. Drawing from a variety of theoretical and interdisciplinary insights, the workshop encourages you to reflect on your personal experiences of inequality and aims to challenge the way in which the issue is typically approached in economics.

Founded in 1968, The Union for Radical Political Economics (URPE) is an interdisciplinary membership organization of academics and of activists. Its mission is to promote the study, development and application of radical political economic analysis to social problems. Concretely, this involves a continuing critique of both the capitalist system, and of all forms of exploitation and oppression. URPE’s mission also includes, coming out of this critique, helping to construct a progressive social policy, and a human-centered radical alternative to capitalism.

In this short video 'Raghuram Rajan’s Dosa Economics Explained', the famous theory of Dr. Raghuram Rajan, ex-governor of Reserve Bank of India (RBI), Dosa Economics, has been explained using a very simple example of Dosa ( a delicacy of India). Here, Dr. Raghuram Rajan tries to explain that low interest rate and low inflation is much better than high interest rate and high inflation.

If there’s one method economists have neglected the most, it’s qualitative research. Whereas economists favour mathematical models and statistics, qualitative research seeks to understand the world through intensive investigation of particular circumstances, which usually entails interviewing people directly about their experiences. While this may sound simple to quantitative types the style, purpose, context, and interpretation of an interview can vary widely. Because of this variety, I have written a longer post than usual on this topic rather than doing it a disservice. Having said that, examples of qualitative research in economics are sadly scant enough that it doesn’t warrant multiple posts. In this post I will introduce qualitative research in general with nods to several applications including the study of firm behaviour, race, Austrian economics, and health economics. More than usual I will utilise block quotes, which I feel is in the spirit of the topic.
Qualitative Methods in Economics: "You Can Observe a Lot Just by Watching"
Modern authors have identified a variety of striking economic patterns, most importantly those involving the distribution of incomes and profit rates. In recent times, the econophysics literature has demonstrated that bottom incomes follow an exponential distribution, top incomes follow a Pareto, profit rates display a tent-shaped distribution. This paper is concerned with the theory underlying various explanations of these phenomena. Traditional econophysics relies on energy-conserving “particle collision” models in which simulation is often used to derive a stationary distribution. Those in the Jaynesian tradition rely on entropy maximization, subject to certain constraints, to infer the final distribution. This paper argues that economic phenomena should be derived as results of explicit economic processes. For instance, the entry and exit process motivated by supply decisions of firms underlies the drift-diffusion form of wage, interest and profit rates arbitrage. These processes give rise to stationary distributions that turn out to be also entropy maximizing. In arbitrage approach, entropy maximization is a result. In the Jaynesian approaches, entropy maximization is the means.

Experimental economists are leaving the reservation. They are recruiting subjects in the field rather than in the classroom, using field goods rather than induced valuations, and using field context rather than abstract terminology in instructions.

Wealth inequality between Black and white people in the US barely has changed in the last 150 years. In her book "The Color of Money. Black Banks and the Racial Wealth Gap" Mehrsa Baradaran, analyzes why also Black banks have not successfully changed this and not enabled Black wealth on a broader scale.
