We present an open economy growth model incorporating various elements of fiscal policy, including government expenditure on education and public capital (infrastructure), budget deficit, internal and external public debt, public consumption, and four tax rates. This detailed description of fiscal policy allows for a systematic study of the relationship between fiscal policy and economic growth. We derive the balanced growth path and analyze its properties, including existence, uniqueness, and stability. The theoretical results are supported by numerical simulations for Poland, with the model calibrated based on data from the years 2010 to 2019. In the baseline scenario, the GDP growth rate converges to 3.98%. However, through appropriate adjustments to fiscal policy, economic growth can be significantly accelerated. Notably, increasing spending on both education and public infrastructure proves to be the most effective way to permanently boost economic growth, even if it requires raising taxes on consumption or increasing public debt.

This paper investigates the linkages between economic growth and fiscal policy under perfect capital mobility. The model incorporates wide range of fiscal policy instruments: the budget deficit, the structure of public debt, public expenditures on education, public consumption, and four tax rates. We prove that two tax rates - on consumption and interest on government bonds held by domestic lenders - are neutral for economic growth: both for the balanced growth path (BGP), and for transitory dynamics. All other parameters of fiscal policy are not neutral. Theoretical results are illustrated with an empirical analysis for Poland based on post-global financial crisis data for the Polish economy (2009-2018). Numerical simulations show that if fiscal policy remains unchanged, Polish economy will converge to the BGP with GDP growing at 2.3%. The best way to accelerate growth is to increase public investment in education. The other budgetary policy instruments are less effective in shaping economic growth. [ABSTRACT FROM AUTHOR]

This paper investigates the relationship between economic growth in Poland and a few metrics of fiscal policy: budget deficit relative to GDP, the structure of public debt, education expenditures, and public consumption. We prove that with constant values of parameters of fiscal policy, over time the economy converges to the balanced growth path which is unique and globally asymptotically stable. Having calibrated the model with statistical data, we demonstrate that in the period of 2000–2016 economic growth in Poland was driven primarily by rapid improvement in the level of human capital (at a rate of 5.4% per annum), and secondarily due to the accumulation of capital (2.7% annually). If recent trends in fiscal policy are continued, the Polish economy will converge to the balanced growth path with GDP growing at 3.7%. This rate may be boosted, if fiscal policy is appropriately adjusted, for example by permanent reduction in budget deficit. We also analyse the effects of changes in the financing structure of public debt. Finally, we present several scenarios of increasing public and private spending on education. [ABSTRACT FROM AUTHOR]
