Supply-Side Economics of a Good Type: Supporting and Expanding South Africa’s Informal Economy

This paper argues that South Africa’s persistently high unemployment is in part explained by abnormally low levels of informal sector activity compared to other developing countries. Using cross-country data, it shows that South Africa is an outlier, with low informality and high unemployment relative to its income level. If South Africa had informality rates consistent with its income level, unemployment would be much lower at around 7% instead of over 25%. The paper explores regulatory barriers, spatial constraints, lack of infrastructure, and crime as key factors inhibiting the growth of the informal sector. To boost informal activity and employment, it recommends a firm-size based policy matrix addressing these constraints, with a focus on regulatory changes to expand market access, zero-rating of licensing fees, provision of critical infrastructure like storage facilities, and transport vouchers and subsidies to connect informal businesses to markets. Implementing such supply-side policy changes could demonstrate the employment potential of the informal sector and build momentum for broader deregulation.

Economic Growth and Complexity in the UAE: Summary Report 

This document summarizes high-level findings on the United Arab Emirates’ (UAE) growth trajectory, economic diversification record, and future prospects. It is based on the work carried out as part of an ongoing collaboration between Harvard’s Growth Lab and the UAE Ministry of Economy (MoE). This collaboration aims to produce novel research-based inputs to inform an ambitious, forward-looking economic policy agenda. Over the last year, it has entailed research on various topics. These have included documenting the country’s past growth path and potential for the future, understanding UAE’s short-run macroeconomic and inflation dynamics, studying trade patterns and free-trade agreements, and looking into labor markets and productivity dynamics. 

This document provides a summary of some of the research stemming from the first phase of work, drawing especially on two reports: Elements of a Growth Diagnostic: The United Arab Emirates (Brenot et al, unpublished) and Economic Complexity: The United Arab Emirates (Tapia et al, 2023). These two reports together lay out research on the UAE’s growth model over the last two decades and use an “economic complexity” lens to analyze where future sources of diversification and growth might come from. The Elements of a Growth Diagnostic report mainly focuses on the past. It examines the UAE’s growth performance between 2000 and 2019 (prior to the COVID-19 pandemic) to understand the drivers of the UAE’s growth model and document the changes in the UAE economy during this time. Economic Complexity: The United Arab Emirates looks at the performance of the UAE’s exports and industrial diversification using a “knowhow” and complexity lens, pioneered by Hidalgo & Hausmann (2009), and also suggests high-potential activities for further diversification. 

As part of a broader research agenda, this summary document is meant as a companion piece to more than a year of past research, but also as a starting point for the next phase of collaboration between the Growth Lab and the MoE. In addition to this summary document and the reports it draws on, there is also a companion Inputs for Policy Design – Tools for Economic Diversification report. The report makes a more policy-oriented contribution, discussing more in-depth three concrete tools to achieve further economic diversification: foreign direct investment (FDI), Free Zones, and Sovereign Wealth Funds (SWFs). 

This summary document highlights the key themes and insights gathered during this past year, while also laying out a set of questions for future research. The rest of this document is structured as follows. Section 2 summarizes key themes of the UAE’s past growth performance and its key drivers at an aggregate, national level. Section 3 goes deeper to describe the current state of the UAE economy by geography and sector, and documents the way the economy has already begun to diversify into non-oil activities. Section 4 further examines the UAE’s diversification path using a complexity approach to better shed light on the UAE’s future diversification prospects. Finally, Section 5 concludes with a set of key takeaways and themes for further research. 

Development in a Complex World: The Case of Ethiopia

This research compendium provides an explanation of Ethiopia’s fundamental economic challenge of slowing economic growth after an exceptional growth acceleration — a challenge that has been compounded by COVID-19, conflict, and climate change impacts. Ethiopia has experienced exceptional growth since the early 2000s but began to see a slowdown in the capacity of the economy to grow, export, and produce jobs since roughly 2015. This intensified a set of macroeconomic challenges, including high, volatile, and escalating inflation. This compendium identifies a path forward for more sustainable and inclusive growth that builds on the government’s Homegrown Economic Reform strategy. It includes growth diagnostics and economic complexity research as well as applications to unpack interacting macroeconomic distortions and inform diversification strategies. Drawing on lessons from past success in Ethiopia and new constraints, this compendium offers insights into what the Government of Ethiopia and the international community must do to unlock resilient, post-conflict economic recovery across Ethiopia.

The research across the chapters of this compendium was developed during the Growth Lab’s research project in Ethiopia from 2019 to 2022, supported through a grant by the United States Agency of International Development (USAID). This research effort, which was at times conducted in close collaboration with government and non-government researchers in Ethiopia, pushed the boundaries of Growth Lab research. The project team worked to understand to intensive shocks faced by the country and enable local capability building in the context of limited government resources in a very low-income country. Given the value of this learning, this compendium not only discusses challenges and opportunities in Ethiopia in significant detail but also describes how various tools of diagnostic work and economic strategy-building were used in practice. As such, it aims to serve as a teaching resource for how economic tools can be applied to unique development contexts. The compendium reveals lessons for Ethiopian policymakers regarding the country’s development path as well as numerous lessons that the development community and development practitioners can learn from Ethiopia.
