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.

WP467. Disruptive innovation: Incumbent’s response to innovation threat

The theory of disruptive innovation has gained significant interest from the academic and business communities, investigating the reasons for inadequate or delayed responses of incumbents to innovation which challenges their established markets. Inadequate responses were explained by the concept of innovator’s dilemma, which postulates how incumbents tend to satisfy their consumers on the established markets, while overlooking opportunities with other consumers. However, the optimal incumbents’ response to disruptive innovation in the normative sense has not been researched. We investigate the choice of the payoff-maximizing strategy in response to the observed market disruption as a choice between different management approaches. Our study shows the importance of the speed of innovation adoption for the choice of the optimal response to innovation. We also show that the response can be delayed in some cases, reflecting the exploitation-exploration dilemma. This new insight complements the reasons of delayed response to disruptive innovation threats.

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.

WP248. Business cycles, innovation and growth: welfare analysis

Endogenous growth literature treats deliberate R&D effort as the main engine of long-run growth. It has been already recognized that R&D expenditures are procyclical. This paper builds a microfounded model that generates procyclical aggregate R&D investment as a result of optimizing behavior by heterogeneous monopolistically competitive firms. I find that business cycle fluctuations affect the aggregate endogenous growth rate of the economy so that transitory shocks leave lasting level effects on the economy's Balanced Growth Path. This result stems from both procyclical R&D expenditures of the incumbents and procyclical firm entry rates. This mechanism generates economically significant hysteresis effects, increasing the welfare cost of business cycles by two orders of magnitude relative to the exogenous growth model. Coupled with potential to affect endogenous growth rates, ample space for welfare improving policy interventions arises. The paper evaluates the effects of selected subsidy schemes and finds some of them welfare improving.

WP206. Who is forked on GitHub? Collaboration among Open Source developers

In this article we investigate which characteristics of the developers involved in the creation of Open Source software favor innovation in the Open Source community. We utilize a unique database, obtained by web-scrapping GitHub from January to March, 2016. The results of the analysis show that higher reputation in the community improves up to a certain degree the probability of gaining collaborators, but developers are also driven by reciprocity, which is consistent with the concept of gift economy. There exists also a statistically significant network effect emerging from the standarization -- developers using the most popular programming languages in the service are likely to have more collaborators. Providing additional contact information improves the chance of having coworkers. The obtained results can be generalized for the population of mature users of GitHub.

WP101. How to perfectly discriminate in a crowd? A theoretical model of crowdfunding.

This paper proposes a theoretical framework to capture the underlying mechanisms of the innovative online crowdfunding. The goal of this work is to emphasize the advantages of crowdfunding platforms over traditional methods of sale, by describing the capabilities unique to such model and processes stemming from them. Namely, the producer's chance for perfect discrimination is discussed, as well as the contributor's role and his decision dilemma. Numerous extensions to the model provide additional insight into crowdfunding platforms.
