This paper develops a simple nonparametric test for perfect competition in markets for homogenous goods. The method only requires data on prices and some aggregate of output. We then generalize the method to account for variable capacity and intertemporal production decisions. We apply the...

Digital skills represent a key dimension of digital transformation, shaping the innovation potential, competitiveness, and long-term sustainability of the European economy. The aim of this paper is to compare the development of digital skills in EU-27 countries from 2018 to 2024 and identify the...

This paper gauges public spending efficiency on human and physical capital formation using non-parametric methods. Input-inefficiency and output-inefficiency are scored across 195 countries using 2010-2020 data. The consistent methodology allows within-country comparison of efficiency across...

Structural quantitative work in international economics typically models trade costs as a log-linear function of exogenous trade-policy variables. We propose a structural approach that allows for a nonparametric relationship and for treating tariff and nontariff trade-policy variables as...

Enterprises face significant growth and survival challenges in highly competitive markets. Many companies fail to meet their tax obligations, which deprives society of essential resources and often results in tax penalties. This article examines whether companies that receive tax fines for...
