A Deep Dive Into Tax Buoyancy Comparing Estimation Techniques In A Large Heterogeneous Panel

This paper provides new empirical evidence on tax buoyancy (tax revenues responsiveness to changes in economic activity) over the period 1990-2020 using a large panel of 185 countries. This study compares short-term and long-term buoyancy coefficients for total tax revenues and different individual taxes by reviewing and contrasting a range of estimators. Our results broadly confirm the main body of the literature on long-term buoyancy hovering around one. We find evidence of lower estimates for short-term buoyancy relative to previous literature, suggesting a limited automatic stabilization power of taxes. As a robustness exercise, in addition to changes in tax rates, we introduce novel control variables for tax exemptions and bases to disentangle discretionary from automatic tax revenue changes. The marginal changes in the results when controlling for policy actions suggest that, on average, the economic cycle does not necessarily influence tax reforms.

In this paper we provide short- and long-run tax buoyancy estimates for 107 countries (distributed between advanced, emerging and low-income) for the period 1980–2014. By means of Fully-Modified OLS and (Pooled) Mean Group estimators, we find that: i) for advanced economies both long-run and short-run buoyancies are not different from one; ii) long run tax buoyancy exceeds one in the case of CIT for advanced economies, PIT and SSC in emerging markets, and TGS for low income countries, iii) in advanced countries (emerging market economies) CIT (CIT and TGS) buoyancy is larger during contractions than during times of economic expansions; iv) both trade openness and human capital increase buoyancy while inflation and output volatility decrease it.

This annual publication gives a conceptual framework to define which government receipts should be regarded as taxes. It presents a unique set of detailed and internationally comparable tax data in a common format for all OECD countries from 1965 onwards. This year’s edition includes a special feature on tax revenue buoyancy in OECD countries.

Lao People’s Democratic Republic (Lao PDR) has made significant headway on its development path over the past three decades. The country’s sustained economic growth has been led by booming commodity exports and substantial inflows of external financing. Many Laotians have seen significant improvements in their well-being. Poverty has declined as household income has increased, and many important development goals in education and health have been achieved. In the face of macroeconomic challenges, a shift from commodity-driven growth to a more inclusive prosperity paradigm that emphasises the creation of broad-based opportunities, human capital development and green sustainability can unlock Lao PDR’s future development. This report presents priorities for overcoming the country’s current fiscal constraints and finding ways to fund this shift. Recommendations address strengthening Lao PDR’s sustainable finance and debt management, revenue generation and tax reform, investment promotion, and data capacity in order to tap into green finance mechanisms.

Research work by the IMF’s staff on the effectiveness of the country programs the organization supports, which has long been carried out, has intensified in recent years. IMF analysts have sought to “open up the black box” by more closely examining program design and implementation, as well as how these influence programs’ effectiveness. Their efforts have also focused on identifying the lending, signaling, and monitoring features of the IMF that may affect member countries’ economic performance. This book reports on a large portion of both the new and the continuing research. It concludes that IMF programs work best where domestic politics and institutions permit the timely implementation of the necessary measures and when a country is vulnerable to, but not yet in, a crisis. It points to the need for a wider recognition of the substantial diversity among IMF member countries and for programs to be tailored accordingly while broadly maintaining the IMF’s general principle of uniformity of treatment.

This flagship publication examines different aspects of the nature and role of international trade in the era of hyperglobalization and considers related policy challenges that will need to be addressed if trade is to contribute to a more stable and inclusive global economic order. Research provides authoritative data and analysis on trade, investment, finance and technology. UNCTAD offers solutions to the major challenges facing developing countries, particularly the poorest and most vulnerable nations. Beyond tailored analysis and policy recommendations, UNCTAD research also generates global standards that govern responsible sovereign lending and borrowing, investment, entrepreneurship, competition and consumer protection and trade rules.
