However, the contestation does not take account of the entire dimensions of sustainable cities. To present a holistic argument, the present study examines the roles of informalities in advancing the sustainable city agenda in sub-Saharan Africa (SSA) by using the sustainable development prism as the analytical framework. A Boolean search methodology was adopted to obtain relevant literature written in the English language from repositories such as Scopus, JSTOR, and ProQuest. The results of a synthesis of the literature suggest that informalities play double-pronged roles in the pursuit of the sustainable city development agenda in SSA. Overall, the emergence of informality is as a result of the failure of the formal systems. They provide employment, secure household income and savings, support national income, provide household basic needs (water access and waste management), and enhance civic engagement. However, informalities contribute to social and gender inequality, insecurity, congestion, and pollution. Based on their positive roles in the advancement of sustainable cities, we recommend a rejection of the prohibitive policies and attitudes towards informalities and call for regularisation as an approach to address the associated ills.

The empirical analysis, based on 205 districts observed over the period 2013–2018, suggests significantly lower levels of political corruption in aligned districts. Partisan alignment reduces corruption by 1.9 percentage points, equivalent to about half of the mean-level in non-aligned districts. In line with political ambition theory, I attribute this result to local politicians aligned with the national government having incentives to control fiscal irregularities within their localities in order to appease their national party leaders and preserve their party's reputation. Alternative explanations are considered through empirical means and can be excluded. The estimated effect is more pronounced in districts that (i) are party strongholds, (ii) have better financial endowments, and (iii) have female local parliamentarians. It appears that political centralization and a politicized bureaucracy, as observed in Ghana, are important explanations for this finding.

This preexisting discrimination suggests an imbalance in decision-making power in the household, which makes empowering the role of women a necessity for the health and development of our communities. Studies have noted how income growth across genders can shift decision-making power in the household. To investigate income growth and its effect on women empowerment, I analyze the Mahatmas Gandhi Employment Guarantee Act of 2005, which offers guaranteed employment to rural households throughout India. Its gradual implementation in three phases over a two year period allows for the use of a difference-in-differences analysis regarding the effects of guaranteed employment by men and women across districts. I analyze two outcomes variables related to women empowerment beginning in 2002 to 2017, including the demand for microfinance and violence against women. Results show that as women take up employment in a district, the demand for credit and savings increases and violence against women decreases. Each result aligns with a broad literature that identifies how income growth and employment empowers the health, social, and economic of status of women.

Intensifying maize production in a sustainable way using the same land will be increasingly important as virgin land becomes scarcer and fallowing becomes less common. This study investigates the sustainability of intensification underway in the African smallholder sector using a uniquely detailed panel survey that combines remote sensing data, soil analysis, yield cuts, GPS area measurements, and detailed field management surveys. Specifically, we quantify the on-farm yield response to nitrogen (N) fertilizer in relationship to 16 soil and field management regimes, adding to the scant literature that combines precise and objective measures of inputs, outputs, and ecological conditions on fields managed by farmers. Furthermore, we examine drivers of soil health using a measure of labile carbon that, unlike total carbon, can be responsive to farm management over the observable time period. Results are based on a representative sampling of Malawi's diverse agroecosystems through a multi-year study for over 1000 fields. We find surprisingly low yield response to N applications, highlighting that fertilizer access alone is not sufficient for sustainable intensification. We find complimentary “good agronomy”, including effective weed management, crop rotations, and organic fertilizer applications are positive influences on maize yield response to inorganic fertilizers. Encouragingly, results show management practices such as incorporating diverse crop residues and manure for a few years can raise labile carbon levels, improving the soil base on which factors jointly determine yields. These findings underscore the importance of education, livestock and crop diversification, and farmer utilization of good agronomy to improve fertilizer use efficiency as a means to promote sustainable agricultural productivity.
查看更多>>摘要：? 2022 The AuthorsAcross sub-Saharan Africa smallholder farmers depend heavily on manual labor supplied by their households, families, and communities. Gender differences in the ability of farm managers to acquire needed labor has been linked with women's disadvantage in agricultural productivity. This in-depth qualitative research in southwestern Nigeria builds on studies that document gender gaps by examining how men and women make sense of the allocation of labor within their households. Insights from observation over the course of one year and interviews with 93 participants are combined with evidence from existing literature to develop a framework that illustrates the conceptual links between constraints on women's time use and the quantity and quality of labor available for their agricultural activities. We find that women's time and labor constraints are rooted in common social expectations that men's farm plots take priority and that a woman should only farm what she can manage without interfering with the agricultural production managed by her husband. Practically, this means that women's household responsibilities and off-farm work limit their own farm labor and their ability to supervise hired labor. The prioritization of men's plots also means that labor is allocated to men's plots first in the day, which results in less labor and potentially less productive labor available for women's farms. Also, women's access to labor is especially constrained by seasonal fluctuations in labor demand because of the precedence given to men's agricultural production. The conceptual framework is meant as a tool to be used in future research on time use, agricultural labor, and gender differences in agricultural productivity. It highlights the ways in which intrahousehold negotiations over labor and time use are not just about maximizing efficiency or productivity, but also about maintaining social hierarchies, roles, and responsibilities.

In contrast, the impact of poverty reduction on subsequent growth has not been systematically investigated. The main objective of this paper is to explore empirically the reverse causality between poverty and growth. Using data from 129 developing countries (44 in SSA) during 1981–2018, this study finds that faster poverty reduction is linked to faster growth in the developing world and especially the SSA region; while faster growth contributes to faster poverty reduction more in the developing world outside of SSA than within SSA. These findings suggest that for faster poverty reduction in the entire developing world but especially in SSA, we need a pro-growth poverty reduction strategy, where interventions directly target poverty reduction, and through that also contribute to faster growth; as a complement to the more conventional pro-poor growth strategy, where interventions directly target growth and only reduce poverty through growth. The main conclusion is that the combined effects of growth on poverty and of the latter on subsequent growth can lead to a virtuous spiral.

The empirical evidence on the causal effects of these approaches on entrepreneurs’ business outcomes is encouraging, but still not substantial enough to be conclusive. This study contributes to this literature by designing and evaluating two training programs, which are adapted to the Jamaican context. The first program provides soft-skills training on personal initiative, including the development of a proactive mindset and perseverance after setbacks. The second program combines soft-skills training on personal initiative with traditional training on hard skills aimed at changing business practices. Both programs are evaluated using a randomized controlled trial involving 945 entrepreneurs in Jamaica. Entrepreneurs are randomly assigned in equal proportion to one of the two training programs or to a control group. The research develops three survey instruments to collect information from entrepreneurs: a baseline survey, a short-term follow-up survey conducted 3 months after the intervention, and a second follow-up survey conducted 12 months after the intervention. Findings indicate statistically significant effects of the intensive soft-skills training, but not of the training combining soft and hard skills, on business outcomes in the short-term survey. The analysis of the data suggests that the main channel through which the intensive soft-skills training improves short-term business outcomes is an increased adoption of business practices. The positive short-term effects of the soft-skills training are concentrated among men and are not significant for female entrepreneurs. Neither the effects on business practices nor those on business outcomes are statistically significant in the second follow-up survey. However, the soft-skills training has persistent effects on targeted soft skills, which are measured with both self-reported and incentivized measures. Theoretical and practical implications of these findings are discussed in the paper.
查看更多>>摘要：? 2022 The AuthorsNil-filing refers to taxpayers reporting zero in all fields of their tax declaration. It is a largely ignored phenomenon in the public finance literature, despite being well known to tax administrators and widespread: half of all registered corporations in Rwanda file nil. This paper sheds light on this issue, using descriptive analysis of administrative data, a randomised controlled trial (RCT), and qualitative interviews with taxpayers and tax officials. We argue that a major reason for nil-filing lies at the intersection between aggressive recruitment campaigns by the Rwanda Revenue Authority (RRA) and taxpayers’ response to a complex and often confusing tax system. Through the lens of nil-filing, we also shed some light on the practical challenges of public administration in low-income countries more generally. By doing this, we challenge the prevailing narrative that governments should always expand the tax base to small and yet unregistered firms, showing some previously undocumented – and unintended – consequences of such a strategy.
查看更多>>摘要：? 2021 Elsevier LtdDemocratic decentralization has been widely adopted across the developing world with the goal of improving local accountability and the delivery of public services. However, outcomes have varied widely depending on the degree of local-level elite capture, cohesion, and governing capacity. This article draws on data from one of the most radical recent cases of fiscal and administrative decentralization: post-Soviet Russia from the mid-1990s to the early 2000s. Drawing upon detailed demographic, survey, and time-series public goods data from each of 83 districts, this article documents growing inequality in service provision over time and shows via a series of spatial regressions that a strong predictor of success in maintaining public goods delivery was the degree of historically accumulated state capacity. This effect is independent of the degree of local ethnic fractionalization, economic development, or civic association. A detailed examination of two case studies at similar levels of ethnic diversity and baseline development - Tatarstan and Buryatia – suggests that legacies of historical state formation established indigenous elites and bureaucratic capacity, resulting in stronger elite-citizen ties and accountability to local actors and concerns. The wide variation of post-decentralization trajectories in Russia, and the eventual push to recentralize control. suggests an important concern for policymakers promoting devolved governance in polities with divergent subnational legacies of historical state development. Where decentralization occurs in contexts that are not uniformly favorable to its success, both the decentralization and democracy-building aspects of devolution reforms may come under threat from bureaucratic centralism.
查看更多>>摘要：? 2021 Elsevier LtdWe use childhood exposures to disasters as natural experiments inducing variations in adulthood outcomes. Following the fetal origin hypothesis, we hypothesize that children from households with greater exposure will have poorer health, schooling, and consumption outcomes. Employing a unique dataset from Bangladesh, we test this hypothesis for the 1970 cyclone that killed over 300,000 people in southern Bangladesh. We find that children surviving the cyclone experience significant health, schooling and consumption adversities, and during their adulthood, have lower probabilities of good health and primary schooling; and lower durations of good health, schooling and consumption. Such adversities are further heightened among the rural and less-educated households. Therefore, public programs benefiting the females and the poor, alongside the development of healthcare and schooling infrastructure, can be useful protective measures against the long-term harms of a disaster.
