Abstract:
This paper examines the state and evolution of the rule of law in Mozambique, focusing on key dimensions such as voice and political participation, judicial independence and accessibility, corruption, access to basic services, personal security, and property rights. Drawing on Afrobarometer surveys, voting data, and conflict records, the paper offer insights into the perceptions and experiences of Mozambican citizens. The findings indicate a deterioration in institutional trust over the past two decades, alongside declining voter turnout in general elections and increasing election-related and political violence. Despite reforms aimed at improving judicial autonomy and accessibility, the legal system remains affected by inefficiencies and regional disparities. Citizens are often subject to bribery when accessing essential public services, and perception of corruption in key institutions remains high. Concerns about fairness and integrity in the land registration process can also weaken confidence in land security and property rights protection. The paper highlights the continued challenges Mozambique faces in consolidating the rule of law, exacerbated by legacies of conflict, political instability, and uneven socioeconomic development.

2. Inequality and agricultural structural change: Evidence from macro and microdata, 1950–present

Abstract:
Since 1950, agricultural productivity has been increasing even as labourers leave agriculture. However, while average productivity of the sector has been converging, within-sector inequality has been increasing. Agricultural income inequality is still less than overall income inequality, but it measures significantly higher when we use higher-quality and more comprehensive survey data. This means not only to observe the entirety of household farm income, but also to measure the magnitude of capital income and corporate profits in the sector. Given the likely increase in agricultural inequality during the process of structural change, I show also the extent to which social protection programmes are both insufficient and poorly targeted for rural populations.

3. How reliable are national accounts estimates of agricultural output?

United Nations University
Abstract:
Measurement errors in macroeconomic aggregates such as GDP have been widely lamented, particularly in low-income contexts. This study investigates the reliability of one component of national accounts, agricultural sector output. Focusing first on the case of Mozambique, we use a series of 12 harmonized national agricultural micro-surveys to construct estimates of gross annual output in the sector. Compared to corresponding national accounts values for the period 2002–20, the micro-survey estimates are about 50% lower. A decomposition exercise indicates this gap is primarily driven by differences in base year levels, offset by higher rates of inflation observed in survey-based producer prices. Triangulating these estimates using household budget surveys, market price, and FAO production data, we find consistent support for the agricultural micro-survey estimates, suggesting real rates of total GDP growth may have been overestimated by 1 percentage point over the period. A cross-country comparison of national accounts and FAO production data indicates positive differences between estimates of agricultural output from the two sources are not unique to Mozambique, but with larger discrepancies among lower-income countries. Systematic investment in reliable and timely agricultural statistics is essential to track progress in the sector.

4. Social protection for Mozambique’s elderly: History, structure, and potential effectiveness

Abstract:
This study assesses the effectiveness of Mozambique's flagship social pension programme, the elderly component of the Programa de Subsídio Social Básico (PSSB). Focusing on three key criteria— programme targeting, reliability, and materiality—we combine administrative data on the universe of beneficiaries with the complete records of the 2017 Population and Housing Census. Merging these datasets at the localidade level, we provide a highly granular view of programme coverage rates and payment delivery regularity. We estimate that in the best case with zero targeting errors, the PSSB-Elderly programme reaches two-thirds of its target group. However, significant regional disparities persist, including undercoverage in poorer regions. Additionally, we document substantial delays in payments since 2023, as well as various inaccuracies in the beneficiary registry. These findings underscore the importance of simple and robust designs for social protection in resource-constrained contexts. They also suggest that expanding programme coverage towards a quasi-universal subsidy in high-poverty locations merits serious consideration.

5. Environmental Kuznets curve and green regulation

Content Type:

Abstract:
In this paper, we first test the validity of the Environmental Kuznets Curve (EKC) hypothesis, using a large sample of approximately 190 advanced and developing countries, over a period of 34 years (1989– 2022). We find that (CO2) emissions respond positively to increasing income per capita, up to a turning point of approximately US$25,000. In a departure from the previous literature, we allow the relationship between economic development and emissions to depend on the stringency of environmental regulation. Our results indicate that environmental policies—and particularly market-based instruments, such as carbon taxes and emissions trading systems—make the EKC lower and flatter. These results are robust to several sensitivity checks, and to the use of regional (rather than global) data. Overall, our results have important policy implications, as they identify economic development as a pathway to environmental improvements. Moreover, we show that environmental policies are an essential means to achieving decoupling of emissions and economic output over the longer term.

6. Fiscal policy and commodity price shocks in South Africa

United Nations University
Abstract:
This paper investigates the effect of commodity price shocks in a commodity-exporting small open economy, and the role of fiscal policy in transmitting these shocks to the rest of the economy. Using South African data, we first estimate an empirical model using a Bayesian vector autoregression model. We then develop a New Keynesian small open economy with labour market hysteresis and commodity price shocks. We find that a commodity price shock typically has an expansionary effect as real GDP and employment increase, which translates into higher tax revenue. The results from our dynamic stochastic general equilibrium model match the data. In addition, despite not modelling the tradable and non-tradable sectors explicitly, we find that there is an opportunity cost associated with taxing the commodity sector more than home production. This results in a higher trade deficit and government spending. Consequently, we also explore the role of countercyclical fiscal policy during a commodity boom.

7. Economic development and inequality of opportunity: Kuznets meets the Great Gatsby?

Working Paper

Abstract:
According to the Kuznets hypothesis, inequality first tends to increase and then decrease as a country develops. Whether borne out empirically, this inverted-U Kuznets curve, as a stylized ‘fact’, has shaped the discourse on economic development and income inequality for decades. In this paper we investigate whether a similar relationship holds between national income per capita and inequality of opportunity: the inequality associated with inherited individual circumstances such as gender, ethnicity, and family background. As, empirically, inequality of opportunity is positively correlated with income inequality (a relationship known as the ‘Great Gatsby’ curve), the relationship between inequality of opportunity and ‘development’ is expected to display the same inverted-U shape. We suggest that the existence of a Kuznets inequality of opportunity curve can be the result of a ‘triangular’ relationship between development, income inequality, and inequality of opportunity. We propose a simple theoretical model that links the three concepts and describes two possible mechanisms. A numerical simulation based on the model illustrates the process. We then draw on the newly published Global Estimates of Opportunity and Mobility database to shed new light on this ‘triangular’ relationship, primarily in a cross-sectional context.

8. Surviving the storm: How climate-related disasters reshape tax morale in sub-Saharan Africa

Working Paper

Abstract:
Climate-related disasters have increased over recent decades, with severe human and economic consequences. While research has examined their macroeconomic effects and impact on households’ income and consumption patterns, little attention has been given to their impact on tax morale—taxpayers’ intrinsic motivation to comply with tax obligations. This study fills this gap by estimating the impact of climaterelated disasters on tax morale in 26 sub-Saharan African countries using Afrobarometer survey data from 2011 to 2021. The analysis considers six climate-related shocks: droughts, earthquakes, extreme temperatures, floods, storms, and wildfires. We hypothesize that the impact of climate-related disasters on tax morale depends on the specific disasters considered, and that these heterogeneous effects work through two key mechanisms: economic inequality and trust in public institutions. First, they can exacerbate inequality by reducing government revenue, increasing economic hardship for vulnerable groups (through loss of livelihoods), and eliciting unequal policy responses from government. Climate-related disasters can also reduce inequality when associated with increased economic hardship for richer households (by destroying their productive assets. Second, tax morale declines when citizens perceive government responses as inadequate or unfair; conversely, it increases if citizens perceive the government to be responding adequately. Logistic regression results confirm this heterogeneity. Droughts, extreme temperatures, floods, and storms reduce tax morale, while earthquakes and wildfires increase it. Incorporating regional heterogeneity shows that the negative effects of disasters on tax morale are more profound in rural areas. Mediation analysis confirms inequality and institutional trust as key transmission channels. These findings underscore the need for inclusive tax policies and effective post-disaster governance to sustain revenue mobilization in sub-Saharan Africa.

9. Carbon taxation and firm behaviour in emerging economies: Evidence from South Africa

Abstract:
This paper provides the first comprehensive analysis of how firms in emerging economies respond to carbon taxation, leveraging detailed administrative data from South Africa—a potential trailblazer for other developing countries with limited state capacity amid the growing global push for carbon pricing. We examine the dynamic impacts of the carbon tax on firm-level outcomes—such as profits, sales, capital, and labour inputs—across manufacturing and mining firms, which are key sectors in the context of the carbon tax. Contrary to concerns that carbon taxes may hinder economic growth or reduce employment, our findings show no evidence of negative average impacts on firm performance or jobs. However, this overall result masks significant heterogeneity in the tax’s effects across sectors, driven by the sector-specific design elements of the South African carbon tax. Firms expecting higher effective tax rates may have intensified their use of emission-intensive machinery and depreciated capital in anticipation of the tax. This behaviour appears to stem from firms resolving regulatory uncertainty or seeking to recover costs from stranded assets.

10. Rethinking development finance in Tajikistan: Towards more sustainable and inclusive fiscal pathways

Working Paper
Institution:
United Nations University
Abstract:
This paper rethinks development finance in Tajikistan through the lens of fiscal sociology, arguing that sustained reliance on foreign aid and external borrowing may weaken state-society trust and erode institutional legitimacy. Anchored in the political economy of development finance, the paper explores how alternative financing strategies, such as tax reform, diaspora bonds, thematic bonds, and blended finance, interact with domestic institutions, investor confidence, and citizen perceptions of fiscal fairness. While external flows have financed essential infrastructure and social programmes, they have also limited incentives for domestic resource mobilization and weakened public accountability. Issues of debt sustainability increasingly constrain long-term planning, while climate finance is emerging as both a challenge and an opportunity for diversifying development funding. Drawing on policy analysis and secondary data, the paper shows that financial instruments succeed not only through technical design but through their ability to reinforce the fiscal social contract. Tajikistan’s case illustrates that without improvements in governance, transparency, and citizen engagement, even well-structured innovations in development finance may fail to gain traction. The findings offer practical insights for low-income countries seeking to reduce aid dependency while building more credible and inclusive systems of public finance.
