Working Papers

Seria wydawnicza WNE WORKING PAPERS prowadzona jest przez WNE UW od 2008 r. i jak dotąd opublikowano w niej ponad 400 prac.

Seria WNE Working Papers służy szybkiemu upowszechnianiu wyników badań prowadzonych na Wydziale Nauk Ekonomicznych UW. Publikowane tu teksty mają charakter wersji roboczych (pre-printów): mogą być uzupełniane lub poprawiane w miarę postępu prac nad tekstem i procesu wydawniczego. Prezentujemy aktualną wersję udostępnioną przez autorów, opatrzoną datą oraz identyfikatorami DOI/ISSN – co ułatwia jej cytowanie i śledzenie kolejnych iteracji. Każdy dokument zachowuje pełne prawa autorskie swoich twórców, a w przypadku późniejszych zmian, autorzy mogą w dowolnym momencie zamieścić zaktualizowany plik lub wskazać miejsce ostatecznego wydania.

Do serii WORKING PAPERS przyjmowane są artykuły pracowników naukowych WNE UW oraz publikacje z konferencji organizowanych na WNE UW. Artykuły powinny dotyczyć ekonomii, mieć charakter oryginalnych prac badawczych, nie być wcześniej publikowane. Przyjmowane są wyłącznie teksty w języku angielskim.

Prace prosimy przesyłać e-mailem na adres: =+QK'N3{DTz6Jw`uHSP5hi_tMU}]#[2vD3l9ul|E`&=4Xd*\F-qODjVFj

Prosimy przesyłać dwa pliki:

(1) główny tekst bez podania tytułu artykułu oraz autorów (plik DOC/DOCX) oraz

(2) stronę tytułową zawierającą: tytuł opracowania, autorów oraz ich afiliację (plik DOC/DOCX). 

Przed przesłaniem tekstu prosimy zapoznać się z szczegółowymi wymogami edycyjnymi.

Redaktorem wydawniczym serii Working Papers jest dr Maciej Bukowski.

WP226. Can fiscal decentralisation curb fiscal imbalances?

The aim of this paper is to study the impact of fiscal decentralisation on fiscal discipline. We use annual data for more than 2400 Polish municipalities, over the years 2002-2014. We introduce the distinction between "de facto" and "de jure" fiscal decentralisation, what is the first novelty of this study. The second novelty is that we control for the characteristics of the political scene and include interactions of decentralisation and political variables. We show that higher decentralisation is associated with higher fiscal discipline and that this result is robust for all our decentralisation measures. We also show that the impact of decentralisation is different, depending on the characteristics of the local political scene. Therefore, its overall effect on fiscal balance is not necessarily straightforward.

WP(15/2013)100. Ethnic Competition or Complementarity: Which Drives (Returns to) Self-employment?

Autorzy: Nestorowicz Joanna, Tyrowicz Joanna
This paper explores the relationship between ethnic competition and complementarity in returns to self-employment. We use detailed individual data from the U.S. censuses. We find that while in general business competition is detrimental to profitabil…

WP100. Ethnic Competition or Complementarity: Which Drives (Returns to) Self-employment?

This paper explores the relationship between ethnic competition and complementarity in returns to self-employment. We use detailed individual data from the U.S. censuses. We find that while in general business competition is detrimental to profitability, higher self-employment concentrations of co-ethnics are associated with increase in returns.

WP84. Political Competition and Policy Choices: The Evidence From Agricultural Protection

This paper investigates whether political competition plays an important role in determining the level of agricultural protection. In order to do so, we exploit variation in political and economic data from 74 developing and developed countries for the post-war period. We use two measures of political competition: one that captures the extent to which political power can be freely contested regardless of election results and one based on vote share at last parliamentary elections. Our results, based on static and dynamic panel estimators, show unambiguously that the level of support for agriculture is the higher, the higher is the level of political competition.

WP51. An experimental study on multi-dimensional spatial product differentiation

This study presents the results of an experiment on spatial differentiation of products in Hotelling-type models with different grades of complexity for companies' choices of space. Three models were compared, including models with a single decision variable (single-dimensional space with automatically calculated prices), two decision variables (single-dimensional space with prices assigned by the participants) and three decision variables (bi-dimensional space with prices assigned by the participants). The research revealed that in more complex conditions, the product differentiation was smaller and that the prices were lower than in a simple environment when the Nash equilibrium was confirmed. Companies that function in complex conditions do not take advantage of the opportunity to make high profits based on product differentiation. This has a greater impact on price rigidity with respect to product variety than could be theoretically predicted. Strategies based on product differentiation are, therefore, less profitable than expected based on theoretical predictions.
