Summary of "Economic Growth and Government Spending in Saudi Arabia: an Empirical Investigation"

Core Content

This working paper investigates the relationship between government spending and economic growth in Saudi Arabia using empirical methods and annual data from 1969 to 2010. The study employs Vector Auto Regression (VAR), Cointegration, and Vector Error Correction Model (VECM) techniques to analyze both short- and long-run effects of different types of government expenditures on economic growth. The focus is on understanding how various categories of spending, such as education, healthcare, public investment, and housing, contribute to growth.

Main Objective

The primary objective of the paper is to re-examine the impact of different components of government expenditure on economic growth in Saudi Arabia. Unlike previous studies that often treat government spending as a single variable, this paper explores the nuanced effects of specific spending categories, aiming to provide more targeted policy recommendations.

Key Findings

• Long-run effects: Private domestic investment, public investment, and healthcare expenditure have positive long-run effects on economic growth.
• Short-run effects: Openness to trade and housing sector spending can boost short-run production.
• Policy implications: The composition of government spending is crucial for economic growth. Policies should be designed to optimize the allocation of government funds to stimulate growth and reduce unemployment.
• Oil dependency: While the oil sector contributes significantly to GDP, it is highly volatile and not a reliable indicator of growth due to its dependence on global oil prices. Therefore, the study uses non-oil GDP as a better measure of economic activity.

Methodology

• The study uses a modified version of Ram's (1986) two-sector production function model, distinguishing between private and government sectors.
• It incorporates a growth equation that includes variables such as private domestic investment, government investment, openness to trade, and various components of government expenditure.
• The VECM method is used to estimate both long-run equilibrium and short-run dynamics. OLS and VAR are also employed as robustness checks.
• Unit root tests (ADF and PP) are conducted to assess the stationarity of variables, confirming that all variables are integrated of order one (I(1)) and stationary in first differences.
• Cointegration tests (residual-based and Johansen) are used to determine the long-run relationships between the variables, with evidence of at least one cointegrating relationship in each model.

Data

• The study uses annual data from 1969 to 2010.
• Variables are measured in real terms using the GDP deflator (1999 = 100).
• The growth rate of non-oil GDP is used for short-run analysis, while the natural logarithm of real non-oil per capita GDP is used for long-run analysis.
• Openness to trade is calculated as the ratio of real exports and imports to real non-oil GDP.
• Private and government investments are expressed as a share of GDP, and all government expenditure categories are measured as growth rates.

Policy Priorities

• The paper emphasizes the importance of directing government spending towards productive sectors such as education, healthcare, and public investment to achieve long-term growth.
• It suggests that current expenditures, particularly in the housing sector, can have a significant short-term impact on economic output.
• Given the high level of unemployment, the study highlights the need to shift the focus of government spending from non-productive to more growth-enhancing areas.
• The findings recommend that Saudi policymakers should consider the structural composition of government spending to maximize returns on economic growth and development.

Conclusion

The empirical results show that while government spending in general can influence economic growth, its impact varies significantly by category. The study provides valuable insights for policymakers in Saudi Arabia to optimize spending allocation and enhance economic performance through targeted fiscal strategies.
