The EU fiscal framework and national fiscal rules: effects on budget balance dynamics
International Economics and Economic Policy · 2026-05-16
articleOpen accessSenior authorAbstract The EU fiscal framework represented by the Stability and Growth Pact (SGP) has been an effective tool for improving average government budget balances. This paper studies how EU and national-level fiscal rules have determined the dynamics of general government budget balances during the last 30 years. The results suggest that the SGP has had, on average, a statistically significant positive effect on the development of general government budget balances, which remains robust when controlling for national fiscal rules and across multiple estimation approaches, indicating effects beyond domestic frameworks. The effects for national fiscal rules appear very heterogeneous and dependent on the specifics of the rules as well as the public sector level they apply to. The effectiveness of different forms of rules for various levels of government can differ significantly due to country-level institutional differences, but the results of the study can help policymakers in designing and implementing more efficient and better targeted fiscal rules.

preprintOpen accessSenior authorLanguage Assessment of Bilingual Children: A Survey Study
Journal of Monolingual and Bilingual Speech · 2026-01-01
article1st authorCorrespondingThere is an increasing number of bilingual children in the United States. The purpose of this study was to identify the current practices of school-based speech-language pathologists (SLPs) who work with bilingual children. This study included electronic surveys from 230 school-based SLPs who work with bilingual children in the United States. Surveys were analyzed using descriptive statistics. Based on the survey responses, current assessment practices of school-based SLPs who work with bilinguals included standardized testing and nonstandardized measures. This survey also collected information on SLPs’ use of interpreters and SLPs’ reported confidence levels when assessing bilingual children. Future studies should further explore accessibility and efficiency of interpreter use in bilingual populations and when the SLP does not speak the child's language.

Abstract Public debt and its development are key questions of public sector economics and fiscal policy. This paper uses the Synthetic Control Method to study how different large-scale steps of European integration and the establishment of the EU fiscal framework have affected government debt in EU Member States. The results point to a notable debt-restricting effect of EU membership and the introduction of the Stability and Growth Pact for a large majority of the studied country groupings as well as for individual countries. Outside of a few individual countries, the actual government debt levels are substantially lower than in the synthetic alternatives.

articleThe amount of language input bilingual children receive influences their language acquisition. This three-year quasi-longitudinal study determined the extent home language input influences measures of expressive and receptive English vocabulary among Spanish-English school-age bilingual children. The study also determined whether a relationship exists between school of attendance and measures of expressive and receptive English vocabulary among the same group of children. One Spanish-English dual-immersion school and one English-only school in Utah participated in the study. Participants were administered two formal measures of receptive and expressive English once a year for three consecutive years. Results indicate that regardless of their home language, all children demonstrated improvements in receptive and expressive English language skills after three years. Between year one and three, the increase in English receptive language measures were statistically significant among the children who primarily heard Spanish at home. Results revealed that all children made advancements in expressive and receptive vocabulary skills, regardless of their home language and the type of school they attended. Findings suggest that exposure to a language other than English at home is not a detriment to English language development. Additionally, bilingual education is as effective as English-only education in fostering children‘s vocabulary skills in English.
Government debt: the impact of fiscal rules at the European and national level

Abstract As Europe and the world surface from the pandemic of 2020–2021, public debt levels have risen substantially, the review of the European Union (EU) economic governance framework is underway and the general escape clause of the stability and growth pact (SGP) is planned to be deactivated at the end of 2023. Against this background, it is important to better understand the dynamics of public debt in the EU. This paper studies how European institutions and sectoral national fiscal rules have affected the formation of public debt. The results suggest that over the last 25 years, the SGP has been an effective tool for lowering government debt levels, at least on average. The establishment of the SGP has been the most effective at lowering government debt, while reforms of the SGP have only had limited effects. The effects of national fiscal rules are heterogenous across different rules and public sector classifications, but it seems that national fiscal rules have at least some effects beyond the SGP in all studied cases. This implies that the EU fiscal framework and EU-level fiscal policies should take into account potential interactions with national fiscal rules and both can be used to increase the effectiveness of fiscal policymaking.
