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.

WP350. The effects of child benefit on household saving

In 2016, a new child benefit was introduced in Poland: a universal benefit for the second and subsequent children in a family and means tested for the first child. Substantial transfers of the new child benefit were granted 60% of households with children. The generous child benefit, equal to 10% of monthly median households' income, caused an unexpected positive income shock for families with children. In this paper, we investigate how the new child benefit affects the household decisions to consume or save the child's income. Applying the difference-in-differences method and Polish Household Budget Survey data for the years 2012-2018, we find a positive effect of the child benefit on household saving. Our estimates indicate that families obtaining the child benefit (treatment group) increased the saving rate by 8 percentage points after the child benefit reform in 2016. Over time, the control group (not obtaining the child benefit) raised the saving rate by 2.9 percentage points.

WP311. Preferences for demand side management—a review of choice experiment studies

This review of choice experiment (CE) studies deals with the valuation of electricity supply attributes in the residential sector. We consider the willingness to pay and the willingness to accept changes in the electricity supply. The results could be used to determine consumers' preferences for demand-side management (DSM) programs and could serve as a reference for formulating policies. DSM is an option for constructing a low-carbon electricity system, improving energy efficiency, and achieving the sustainable development of an economy. The results from CEs justify investment in new solutions. The research shows that consumers are open to DSM, but they prefer simple programs to complex ones. Decision-makers could introduce DSM programs that enable power outages and provide compensation for households. The societal advantages of DSM are not obvious to consumers, so the implementation of DSM requires communication and more research on peoples' preferences.
