Machine Learning and Econometric Approaches to Fiscal Policies - Understanding Industrial Investment Dynamics in Uruguay - 1974-2010

Aug 3, 2026

This paper examines the impact of fiscal incentives on industrial investment in Uruguay from 1974 to 2010, combining econometric modeling with machine learning to assess short- and long-run effects. Findings indicate fiscal benefits meaningfully support long-term industrial growth, especially when accompanied by stable macroeconomic conditions, public investment, and improved access to credit. Machine learning further reveals nonlinear interactions between fiscal incentives and macroeconomic variables such as exchange rates. Results inform policy design for emerging economies where tailored incentives paired with broader reforms can strengthen industrial development.

Fiscal Incentives and Their Impact in Emerging Economies

Machine Learning and Econometric Approaches to Fiscal Policies: Understanding Industrial Investment Dynamics in Uruguay (1974-2010) Diego Vallarino, PhD Independent Researcher Atlanta, USA September 2024 Abstract This paper examines the impact of fiscal incentives on industrial investment in Uruguay from 1974 to 2010. Using a mixed-method approach that combines econometric models with machine learning techniques, the study investigates both the short-term and long-term effects of fiscal benefits on industrial investment. The results confirm the significant role of fiscal incentives in driving long-term industrial growth, while also highlighting the importance of a stable macroeconomic environment, public investment, and access to credit. Machine learning models provide additional insights into nonlinear interactions between fiscal benefits and other macroeconomic factors, such as exchange rates, emphasizing the need for tailored fiscal policies. The findings have important policy implications, suggesting that fiscal incentives, when combined with broader economic reforms, can effectively promote industrial development in emerging economies.

Introduction The analysis of private industrial investment determinants, particularly the role of government incentives, has been a central focus in economic theory with direct implications for public policy design. In Uruguay, the Industrial Promotion Law of 1974 and the Investment Promotion Law of 1998 represented a pivotal shift in efforts to stimulate industrial sector growth through fiscal incentives. This study examines how these incentives shaped investment decisions between 1974 and 2010, and how the results hold when employing advanced analytical techniques like machine learning. Recent literature has highlighted that fiscal incentives not only reduce the cost of capital but also enhance market efficiency by fostering competitiveness and innovation in the private sector (Akbulaev & Muradzada, 2024; Appiah et al., 2023) . However, the effectiveness of these mechanisms depends heavily on the macroeconomic context and institutional structure of the recipient country. This paper addresses these challenges by adopting a mixed-method approach that combines traditional econometric models with advanced machine learning techniques, such as Random Forests and XGBoost, to assess the sustainability of previous findings. The primary objective of this research is to establish the robustness of fiscal incentives as determinants of private industrial investment in Uruguay. By applying newer data exploration techniques, the study seeks to validate, refine, or refute earlier conclusions about the impact of fiscal benefits on the Uruguayan economy, while offering fresh insights into the relationship between investment, employment, and economic growth. 2. Theoretical Framework 2.1 Private Investment and Economic Growth: New Perspectives The relationship between private investment and economic growth has been extensively studied in economic literature, establishing investment as a key variable for sustained economic development (Appiah et al., 2023) . Recent studies, such as Miar et al. (2024), demonstrate that capital investment has a multiplier effect, generating positive externalities in the economy by increasing not only the level of economic activity but also aggregate productivity. The direction of causality between investment and growth, however, remains debated. While authors like Kuznets (1973) and Maddison (1983) defend a positive correlation, recent research suggests that private investment can play a dual role: both as a result of economic growth and as a driver of it. Akbulaev et al. (2024) emphasize the importance of investment shocks i

FAQs

How does the study evaluate the effect of fiscal incentives on industrial investment in Uruguay?

It combines traditional econometric models with machine learning techniques to measure both short-term and long-term effects on industrial investment decisions from 1974 to 2010.

What factors besides fiscal incentives influence industrial growth according to the results?

The study highlights the importance of a stable macroeconomic environment, public investment, and access to credit, which together support long-term industrial development.

Why do the authors use machine learning models in addition to econometrics?

Machine learning helps capture nonlinear interactions between fiscal benefits and other macroeconomic factors, such as exchange rates, that traditional models may miss.
