This study aims to expand the conventional tax effort model to incorporate relevant economic freedom variables to investigate whether economic freedom fosters tax revenue performance in `sub-Saharan Africa (SSA).

This study uses data from 42 countries across the four sub-regions of SSA from the period 2005 to 2012 with 252 year-country observations in an unbalanced panel method. The data were statistically treated using feasible generalised least square (FGLS) and panel-corrected standard errors (PCSE) estimate techniques.

The findings are twofold. First, the principal finding of the study suggests that economic freedom promotes tax revenue performance. Precisely, the FGLS analysis indicates that property rights freedom, freedom from corruption and investment freedom, as well as the composite economic freedom, exerted positive significant impact on tax revenue performance. This implies that country, which attained high degree of economic freedom, is likely to have higher tax-to-GDP ratio than a country with low level of economic freedom. Secondly, the results of most conventional variables conform to the prediction in the traditional theory except per capita income. Specifically, agriculture share in GDP and per capita income indicate negative significant relationship with tax revenue performance.

Because little is known empirically about the connection between economic freedom and tax revenue performance, this study extended the conventional tax effort model to incorporate the economic freedom to bridge the knowledge gap due to the absence of empirical evidence on the relationship between economic freedom and tax effort.

This paper aims to explore the effect of non-resource tax revenue instability on non-resource tax revenue in developed and developing countries.

The analysis has used an unbalanced panel data set of 146 countries over the period 1981–2016, as well as the two-step system generalized methods of moment approach.

The empirical analysis has suggested that non-resource tax revenue instability influences negatively non-resource tax revenue share of gross domestic product. The magnitude of this negative effect is higher in less developed countries than in relatively advanced countries. This negative effect materializes through public expenditure instability: non-resource tax revenue instability exerts a higher effect on non-resource tax revenue share as the degree of public expenditure instability increases. Finally, non-resource tax revenue instability exerts a higher negative effect on non-resource tax revenue share as economic growth volatility rises, inflation volatility increases and terms of trade instability increases.

The main policy implication of this analysis is that policies that help ensure the stability of non-resource tax revenue also contribute to improving countries’ non-resource tax revenue share. For example, governments’ measures that help cope with or prevent the severe adverse effects of shocks on economies (shocks that could translate into higher tax revenue instability) would ultimately help enhance countries’ tax revenue performance.

The severity of the current COVID-19 pandemic shock (which is a supply and demand shock) and the macroeconomic uncertainty that it has generated – inter alia, in terms of economic growth instability, terms of trade instability, inflation volatility and public expenditure instability – are likely to result in severe tax revenue losses. Governments in both developed and developing countries would surely learn from the management of this crisis so as to prepare for possible future economic, financial and health crises with a view to dampening their adverse macroeconomic effects, including here their negative tax revenue effects.

To the best of the author’s knowledge, this topic is being addressed in the empirical literature for the first time.

The purpose of this paper is to comprehensively examine Ghana’s tax reform programme and investigate whether it has facilitated the revenue mobilization capacity of the overall tax system and of individual taxes on the basis of estimates of tax buoyancies and elasticities.

This study uses the proportional adjustment approach to estimate tax buoyancies and elasticities of the overall tax system and of individual taxes for the pre and post tax reform period over the 1970-2013 period.

The results show that in general, tax reforms had a positive influence on the overall tax structure and on the individual tax handles as evidenced in the more than unity buoyancy and elasticity. All the individual taxes, except excise duties, recorded buoyancies and elasticities of more than unity during the reform period.

Tax authorities ought to move away from income-based taxation which discriminates against saving and investment, in favour of consumption-based taxes in conformity with international standards. Emphasis must also be placed on those taxes that have high revenue elasticities. These taxes include the personal, corporate, the Value Added Tax, and the import duties.

In this study, the paper extends and disaggregates the data on taxes, account for discretionary tax changes from the historical time series data, and use the adjusted historical time series data to estimate tax elasticity. The study therefore provides an in-depth understanding of the effects of the tax reforms on the overall tax system and of individual taxes in Ghana.

This paper assesses the impact of tax reforms on tax revenue mobilisation in Ghana.

The autoregressive distributed lag model together with dynamic ordinary least squares and fully modified least squares techniques were employed on a time-series data spanning from 1980–2018. Exploiting data from IMFs monitoring of fund arrangements database, an index of tax reforms is constructed as a function of the number of successfully implemented tax-related reforms and policy measures per year over the study period.

Having established the presence of co-integration between tax revenue and its determinants, this paper finds strong evidence that tax-related reforms exert positive and significant impact on tax revenue generation in Ghana. Among other covariates, the results show that the tax base (real GDP), public debt and education (human capital index) significantly boosts tax revenue in the long run.

The success of tax reforms in boosting revenue mobilisation has been examined in light of the buoyancy and elasticity of the tax system in Ghana, albeit with little emphasis on the extent to which tax reforms contribute to tax revenue mobilisation from econometric perspective. This paper fills this gap in the literature by analysing the impact of tax reforms on tax revenue mobilisation in Ghana. As a recommendation, well-designed and implemented tax reforms and policies aimed at increasing the tax base, education and effective utilisation of funds from public debt promise to be instrumental in boosting tax revenue in Ghana.

In the academic debate, the tax–growth relationship is always a controversial one. This paper aims to investigate the relationship between tax structure and economic growth in India for the period 1980-2016. After controlling for total tax revenue share to GDP in the estimation model, the authors examine the long-run and short-run relationship between tax structure and growth in India.

Auto-regressive distributed lag (ARDL) model has been used in this study. This bound cointegration model has certain advantages to the traditional cointegration model. This study also applies the threshold cointegration test of Hansen and Seo (2002) for examining non-linearity in tax–growth nexus.

The analysis shows that income tax share, corporation tax share and excise tax share are harmful to growth in the long-run. While the custom share is enlarging the growth performance. Corporation tax share is also reducing growth in the short-run. Following the Pesaran et al. (2001) approach of ARDL bound testing, the authors find the existence of a long-run relationship between studied variables. However, this study does not find any existence of threshold effect in the tax–growth relationship for India.

Based on the empirical findings, the author suggests that the prime tax change, which has the potential to impact both long-run growth and short-run economic recovery is the reduction of corporate tax rate with sustainable revenue generation. It will definitely enlarge the foreign direct investment, saving and investment in India.

This study will be a contribution to the empirical literature by investigating “tax–growth” relationship in the Indian case. To the knowledge, this will be the first study to examine this relationship for India with a recent data set.

This paper examines the short- and long-run effects of foreign direct investment (FDI) on tax revenue in Ghana.

The paper adopts the autoregressive distributed lag approach to estimate FDI’s long-run and short-run effects on tax revenue. The study uses time-series data from 1983 to 2019 for Ghana, mainly obtained from The Bank of Ghana, the World Bank and the IMF.

The results show that, in the short-run, FDI has no significant effect on direct tax revenue and total tax revenue but significantly hurts indirect tax revenue. In the long run, however, the results show that FDI has significant positive effects on indirect tax revenue and total tax revenue but no significant effect on direct tax revenue.

Empirical studies often fail to analyse the short-run and long-run effects of FDI on tax revenue. This study contributes to the mixed literature by analysing the short-run and long-run effects of FDI on tax revenue in an emerging market context. Additionally, this study employs three tax revenue measures in analysing the nexus.

This paper focused on financial constraints scenario and tax planning activities of banks in Ghana. The study explores how financial constraints could motivate the banks to pursue tax planning mechanism and the implication on tax revenue mobilisation.

The paper followed generalised method of moments and fixed effect estimators to investigate the financial constrained-tax planning activity nexus. Simulation approach is adopted to provide financially constrained bank scenario. Besides contemporaneous analysis, sensitivity analysis is conducted to determine time varying effect. Data from all the 20 commercial banks which have operated from 2008 to 2018 were used.

The paper found that when banks are faced with financial constraints, they exhibit lower cash-effective-tax-rate. The decomposition analysis also revealed that financially constrained banks are likely to take on both short- and long-term tax planning opportunities. The paper also found evidence of persistence in the tax planning activities under financial constrained scenario.

This paper is one of the few studies which have extended the tax planning literature to the Ghanaian banking sector. Further novelty is seen from the development of financial constraint scenario from liquidity and solvency. Liquidity and solvency are the anchors for continuity of banking operation and sensitive to regulatory watch and sanctions. Therefore, by applying simulation approach to trigger financial constraints scenarios from these fundamental indicators reveals the extent to which commercial banks rely on tax planning opportunities to mitigate the consequence of financial constraints.

This paper examined tax compliance and its impact on agrochemical traders in Ghana.

Based on the registered agrochemical lists obtained from the Plant Protection and Regulatory Service Department, 92 agrochemical traders were sampled for data collection. Probit regression was used to estimate determinants of tax compliance, whereas the Inverse Probability Weighted Regression Adjustment Model was employed to evaluate the impact of tax compliance on business performance.

The results revealed that age and gender relate positively to enforced tax compliance, while education positively impacts voluntary tax compliance. Nonetheless, tax rate, trust and monthly sales positively affect voluntary tax compliance but negatively impact enforced tax compliance. Inversely, while authorities’ power negatively impacted voluntary compliance, it positively influenced enforced tax compliance confirming the Slippery Slope Framework.

To the best knowledge of the authors, this paper is the first to investigate tax compliance determinants and impact among agrochemical traders, despite the tremendous growth of the agrochemical sub-sector in Africa and Ghana. Therefore, this study makes a modest contribution to empirical studies that validate the Slippery Slope Framework in promoting tax compliance in the agricultural and agribusiness sectors of a developing country. Similarly, it also unearths the impact of tax compliance on agribusiness growth which has yet to be highlighted in the extant literature.

The purpose of this paper is to explore the relationship between public governance quality and tax compliance behavior in developing countries in terms of what transpires between governments and citizens, leading the later to pay or to abstain from paying tax. The study argues that socioeconomic condition is a mediator in the relationship and explains how and why it is so.

This study adopts the conceptual approach and connects the concepts through synthesis of literature and previous research findings.

The study concludes that socioeconomic condition mediates the relationship between public governance quality and tax compliance behavior in developing countries. Socioeconomic conditions appear to be a broader, clearer and more practical concept for measurement purpose than public goods/spending as currently understood in the literature.

The study is a conceptual effort, and there may a be need to undertake further empirical investigations. Developing countries vary in their socioeconomic conditions, and there is a need to acknowledge country-specific circumstances.

The implication of the finding includes the need for further research on the concept of socioeconomic condition, and how and why it influences tax compliance behavior in developing countries. Stakeholders and governments should monitor the impact of policies and actions on the socioeconomic condition of citizens to ensure they are satisfied. Their dissatisfaction leads to the boycott of the tax system which adversely affects economic development.

This study makes an original contribution by exploring socioeconomic conditions as a mediator between public governance quality and tax compliance behavior in developing countries. It is a significant contribution that is capable of shifting the direction of tax compliance research in developing countries due to its practical realities.
