Working Papers

The WNE Working Papers series has been published by the Faculty of Economic Sciences at the University of Warsaw since 2008.

The WNE Working Papers series provides a fast, open channel for disseminating research conducted at the Faculty of Economic Sciences, University of Warsaw. The papers hosted here are working versions (pre-prints) and may evolve as authors refine their analyses, incorporate feedback, or progress through formal peer-review. What you read is the current version released by the authors, timestamped and assigned DOI/ISSN identifiers to ensure precise citation and version tracking. Copyright remains with the authors, who may, at any time, upload a revised file or add a note directing readers to a later, peer-reviewed publication.

The Working Papers series accepts articles by research employees of the Faculty and publications from conferences organised at the Faculty of Economic Sciences at the University of Warsaw. Articles should be original research papers which have not been previously published, on the subject of economics.

WP524. From Information to Communication: Generative Interaction in the Production of Knowledge

Economic analysis of information explains how existing knowledge is distributed, revealed, and used, while the economics of innovation treats new ideas as outcomes of search and recombination. This paper examines a distinct role of communication in knowledge production: interaction can change the course of search itself. We define the mechanism as adaptive feedback, in which one participant responds to the current state of another participant's reasoning and thereby alters the directions subsequently explored. The resulting idea need not be contained in the feedback or previously possessed by either participant. In stronger cases, interaction can change the representation of the problem and make previously unavailable hypotheses accessible. The paper distinguishes this generative role of interaction from information transmission and access to others' knowledge. It argues that institutions shape knowledge production through both information structure and interaction structure, including the timing of interaction and the balance between independent search and mutual influence.

WP504. Clashing narratives about economic inequality in the economic and sociological textbooks

Students of introductory economics courses pointed out that economic inequality the most significant challenge in the 21st century (Bowles & Carlin, 2020). However, there is limited research on how this issue is portrayed in introductory textbooks. Our study aims to investigate the presentation of economic inequality in economics textbooks compared to sociological ones. We conduct a mixed-method study to examine differences in how introductory economics and sociology textbooks portray economic inequality. By focusing on the comparison between economic and sociological textbooks, we aim to highlight the importance of an interdisciplinary approach to studying economic inequalities, as advocated by economist Thomas Piketty (Korom, 2019). Comparing textbooks across disciplines is essential for informing curriculum development, encouraging interdisciplinary learning, and enhancing the relevance of education to real-world issues. This comparison provides insights that help integrate diverse perspectives on economic inequality into educational practices in both disciplines. Our analysis includes twelve introductory economics textbooks and three introductory sociological textbooks. We find significant differences: top-selling economics textbooks focus on statistical measurements of inequality and the trade-off between equality and efficiency, while sociological textbooks consider economic inequality from historical, cultural, and philosophical perspectives.

WP255. Innovation and endogenous growth over business cycle with frictional labor markets

This paper proposes a microfounded model featuring frictional labor markets that generates procyclical R&D expenditures as a result of optimizing behavior by heterogeneous monopolistically competitive firms. This allows to show that business cycle fluctuations affect the aggregate endogenous growth rate of the economy. Consequently, transitory shocks leave lasting level effects. This mechanism is responsible for economically significant hysteresis effects that increase the welfare cost of business cycles by two orders of magnitude relative to the exogenous growth model. I show that this has serious policy implications and creates ample space for policy intervention. I find that several static and countercyclical subsidy schemes are welfare improving.
