While there is mounting evidence that the Covid-19 pandemic has increased socioeconomic inequality, there is still a need to understand the exact channels of impact and what role the policy response has played in different contexts. It is also necessary for governments to be clear about the efficiency of the type of policies they have implemented throughout this period, in terms of the redistributive and/or regressive effect both from an inequality and poverty perspective. Indeed, we know that the amount of additional social spending (excluding health) implemented during the pandemic reached almost 3% of GDP in Colombia and only 0,2% in Mexico. However, research has not yet demonstrated whether the redistributive policies introduced by the Mexican and Colombian governments in response to the Covid-19 crisis have had any positive effect on the distribution of economic and social resources in these two countries.

The project will seek to understand what has been the redistributive impact of social and fiscal policy in Mexico and Colombia, in the context of the policies implemented during the Covid-19 pandemic.

This research project will be conducted as follows: 

1. Using the framework of the Commitment to Equity (CEQ) methodology, an analysis aiming to differentiate what has been the progressivity or regressivity of the policies implemented during the Covid-19 pandemic will be conducted. This analysis will take into account the main beneficiary groups of these policies and will include a comparison between the budget amount and the efficiency of the policies identified in terms of inequality and poverty reduction.  
2. A desktop analysis of the decision-making will also be carried out to understand how the redistributive effects of the policies implemented were envisaged by the governments. 

The results of this project are presented in the following research paper: Promoting a More Progressive Approach - Evaluating the Impact of Social and Fiscal Policies in Mexico and Colombia amidst the Covid-19 Pandemic (2025)

This research paper analyzes the redistributive impact of some fiscal policies and social programmes (direct taxes and transfers) before and after the pandemic Crisis in Mexico and Colombia, following the CEQ methodology.

This project is a follow-up of the research project developed by CEEY and El Colegio de México in the first phase of the EU-AFD Research Facility on Inequalities. The results showed the need for structural changes to break the bottlenecks of social mobility and reduce inequality in Mexico. 

Based on the above, the new phase of the project focuses on the knowledge base that will inform the setting up of care systems in the states of Guanajuato and Nuevo Leon and in the municipality of San Pedro Garza Garcia. 

Guaranteeing the right to care in the Constitution is essential to advance on the basis of social consensus. In order to define the articulation mechanisms in a law, it is necessary to understand the care systems at different levels as transversal and multipurpose policies that are worth discussing collectively, as they imply much more than the already great challenge of expanding the existing infrastructure of services and social spending. The Care Economy also implies creating fiscal strategies to redistribute paid and unpaid work, adapted policies for those who require care and for caregivers, social co-responsibility and co-responsibility of the private sector.

Therefore, it requires more and better statistical information, strengthening surveys and data systems, as well as developing studies to make visible the interdependence of care with multiple agendas, identifying care needs and their characteristics, available supply and unmet demand, allowing for strategic planning and follow-up from the short to the long term, starting with priority groups that include children, people with disabilities, the sick and elderly, and their caregivers.

Given the above context, the objective of this project is the construction of two products that address two identified needs:

1. a design proposal for a state and municipal-level care system: it is necessary to develop a care system designs that address the structural inequalities for which their creation is sought. In this sense, it is necessary to establish a complete, functional and sustainable design.
2. a proposal for the collection and systematization of primary information for the design and/or monitoring of the care system: a second need arises from the above in terms of systematization of primary and administrative information that feeds, as far as possible, the original design of the care systems, as well as their monitoring over time.

This research project proposes to estimate the distributive effect of gasoline taxes using a fiscal incidence considering these effects in the context of Mexico´s fiscal system, including the principal tax and spending instruments. 

In 2014, Mexico’s Finance Ministry (SHCP) introduced a special tax (IEPS) on carbon as a green tax aimed at reducing the green gas emission associated with fossil fuels, mainly gasoline and diesel. However, the tax revenue (4699 million pesos in 2014) and the environmental impact of this tax are marginal: in the past decade, until 2014, this tax had a negative value, thus working as a subsidy. Since that year, it became a tax, which has grown significantly in recent years, representing close to 300 billion pesos in 2019 and 2020. This is therefore in effect by far the most important green tax implemented in Mexico today. 

This analysis is of particular interest for Mexico at present because the transition from fuel subsidies to fuel taxes represents in effect the principal tax reform implemented in Mexico over the last decade in terms of both tax revenue (from -300 to +300 billion pesos in tax revenue) and distribution. Gasoline taxes have significant impacts on all the population, both directly on middle- and higher-income households through private transport, but especially indirectly for lower income households through public transport and transport costs for all goods and services, notably food. Preliminary analysis at the Fiscal Policy Equity Lab (FPEL) reveals that the increase in the indirect tax burden for the poor associated to gasoline taxes may reverse the effect poverty-reduction effect of direct transfers, even after their recent expansion. 

Quantifying these impacts precisely will allow the design of compensatory instruments to protect the poorest and most vulnerable groups from the regressive effects of these taxes.

This project is a joint undertaking between RIBOS, CEQ Institute and LNPP. It seeks to estimate the effect of green taxes in the context of the overall Mexican tax system through the international methodology developed by the Commitment to Equity Institute (CEQI), using INEGI data from the Encuesta de Ingresos y Gastos de los Hogares (ENIGH) for 2014-2020, among other data sources. 

This methodology will allow an estimation the effect of green taxes in the context of the overall fiscal system. This methodology facilitates comparability in time and space, and generates a wide variety of incidence indicators, including effects on the income Gini coefficient as well as income poverty using national and international poverty lines. 

This project ultimately aims to provide Mexican policy makers and stakeholders with timely analyses of the effects of tax policies on inequality and poverty. The research conducted will therefore result in: 

• a research paper,
• a policy brief whose analysis is based on the collaborative intelligence technique. Two sessions in which the model calibration and hypotheses will be discussed following the collaborative modeling framework. Participants in the sessions will be members of the expert network and key tax policy makers.

Despite a renewed interest for the notion of “commons” within the academic world, little work has been done about land and housing issues in cities of the Global South.

Yet access to urban land is a major issue for dwellers of these rapidly growing cities and a determining factor for the improvement of their living conditions and for their access to “adequate housing”, according to UN terminology. The mainstream approach to urban land tenure, based on full individual private ownership and the free market, generates speculation and land grabbing, and exclusion of the most precarious households.

The critical dimension of the commons notion opens up innovative ways to produce housing in the Global South, according to plural perspectives that take into consideration the inhabitant’s needs and their agency abilities.

This research project aimed to highlight the diversity of hybrid, permeable, evolving commons within space and time.  These commons aim at getting and securing access rights to land and housing and associated services, which often arise from unexpected opportunities.

The research team looked at innovative ways of holding land: commonly held, with a housing function and in a nonspeculative perspective (when the transfer of land is carried out according to a framework decided beforehand by a community, without any capital benefit).

The methodology was based on case studies in developing cities:

• The first phase of the study (2017-2018) led to three field surveys in Burkina Faso, Kenya and India.
• The second phase (2018-2020) consisted of two additional field surveys (Brazil, Mexico), as well as the follow-up of the work carried out in New Caledonia by students in the framework of the School of Urban Affairs (Master’s Degree « Urban Planning Cycle») of Sciences Po Paris.

The team consisted of:

• An academic with authorization to supervise research (HDR), who directed the study;
• A research engineer, who provided the scientific coordination of the study;
• Local researchers specialising in land and urban issues in survey countries.

The study consisted of five phases: documentary research, field research, data processing, drafting of deliverables, valorisation of  research findings. 

This research project resulted in the publication of several research papers:

• “Land-based commons for inclusive cities” (available in French): this research paper presents the conclusions of 8 case studies, focused on securing popular habitat through shared ownership of the land.
• “Does Mexico’s social land still bear commons?” (available in French): Mexican common land has undergone major transformations since the 1990s. This research paper presents the study on the outskirts of the metropolitan area of Mexico City led by the students of the Urban Planning Programme of Sciences Po Paris, under the supervision of Jean-François Valette.
• “Regularizing Rio favelas through land pooling?”: the paper sheds light on an original system of collective land regularization in precarious neighborhoods, which puts into practice the notion of “plural property” running through Brazilian law, and which defends the right of the inhabitants to remain in place.
• “User cooperatives in Uruguay: the challenge of housing as common” (available in Spanish)

"The commons can be understood as a social policy of housing, offering access to housing to the most vulnerable social categories. Moreover, they can provide an alternative path to classical public housing policies which favor individual private property. Indeed, even though these initiatives emerge from dwellers organizations, they might be supported and framed by national governments. Often acknowledged, supported and even presented as standard to be followed, the commons have drawn increased attention recently from dwellers federations, associations, NGOs and international institutions that document their functioning and contribute to the international circulation of these alternative ideas."

In Mexico, more than 40 percent of the population is under the official poverty line. At the same time, Mexico is characterized by a society in which the socioeconomic origin condition is highly related to life achievement, especially on the extremes of the socioeconomic distribution (Vélez-Grajales et al, 2014). On this matter, empirical evidence shows that once the population is divided by quintiles, 48 out of 100 that were born in the lowest quintile stay there for the rest of their lives. Above the rest of them, i.e. those who are able to move to another quintile, 22 reach the second quintile. In summary, previous result leaves in poverty 70 percent of those with origin in the first quintile. It has to be noted that only 4 out of 100 that were born in the lowest quintile will move up to the top quintile.

On the other hand, above those that were born in the top quintile, 52 out of each 100 stay there for the rest of their lives. Moreover, above those that experience downward mobility, 28 out of each 100 move to the fourth quintile, i.e., 80 out of each 100 that were born in the top quintile will stay at least in the fourth quintile. Finally, it has to be noted that only 2 out of 100 that were born in the top quintile will move down to the lowest quintile. This means social mobility is very low.

This project is part of the first phase of the Research Facility on Inequalities, coordinated by AFD and funded by the European Commission's Directorate-General for International Partnerships over the 2017-2020 period. The first phase of the Facility has led to the conduct of 22 research projects and the publication of around 100 research papers and policy briefs.

How are economic inequality and social mobility related? Is it possible that the highest levels of socioeconomic persistence (lower social mobility) in terms of origin determined, in part, both perception and tolerance against economic inequality? The Mexican case, which is one where socioeconomic regional disparities are significant, represents a good option to analyze if such relationship holds. Moreover, there is still a gap in the literature for explaining the mechanisms behind the observed negative relationship.

Additionally, an important and relevant unanswered question for the Mexican case is the perception of Mexicans about inequality and social mobility levels. What if Mexicans think that the country is one of equal opportunities and results for all? Policy implications should be different among different perception scenarios. In any case, it is necessary to get information in order to understand the mechanisms at household and local level that explain the potential distance between perception and reality.

First, using a multivariate analysis method, relative intergenerational mobility can be estimated for each macro-region of the country. Several inequality measures will be estimated, but for several points in time. The researchers have chosen to do so because it is possible that not current but origin economic inequality is the relevant one for intergenerational social mobility. Once the relationship is estimated, a discussion on the mechanisms behind it should be developed. The empirical analysis will be mainly based on the “Encuesta ESRU de Movilidad Social en México 2017”.

Additionally, work with groups in 4 different cities with different levels of socioeconomic performance will be held. The researchers expect to do fieldwork in at least two different spots within each city: one for a group of medium-high socioeconomic level and one of medium-low socioeconomic level. The interview will include a measure for both inequality and social mobility. In such a way, the researchers will be able to understand in a better way the relationship between perceptions and objective measures on the variables of research interest.
