When instability increases the effectiveness of aid projects by Patrick Guillaumont( )

9 editions published between 2006 and 2016 in English and Undetermined and held by 142 WorldCat member libraries worldwide

The authors assess the effect of economic instability on the success of projects funded by the World Bank using the outcome of the projects, which is a notation of their overall success determined by the Bank's Independent Evaluation Group. It has been argued in macroeconomic studies that aid effectiveness is higher in vulnerable countries because it dampens the negative effects of shocks. The authors show that this finding is not inconsistent with the observation that the success of the projects is lower in an unstable environment. Instability, in particular the instability of exports, harms aid projects as it harms the rest of the economy, while the success of projects decreases when the total amount of aid received increases, due to absorptive capacity limitations. But this decrease is slower when instability is higher, showing a positive effect of aid through its stabilizing impact. The authors find the same results keeping only the projects funded by nonconcessionary loans, which suggests that the cushioning effect of aid extends not only to aid funded projects but to whole sets of projects. Corroborating macroeconomic findings, their results lead to the same conclusion that more aid should be allocated to more vulnerable countries, in spite of the lower success of the projects in an unstable environment: project evaluations cannot include the macrostabilizing effect of the aid delivered through projects
Subsidies and the persistence of technology adoption : field experimental evidence from Mozambique by Michael R Carter( )

6 editions published in 2014 in English and held by 77 WorldCat member libraries worldwide

We report the results of a randomized experiment testing impacts of subsidies for modern agricultural inputs in rural Mozambique. One-time provision of a voucher for fertilizer and improved seeds leads to substantial increases in fertilizer use, which persist through two subsequent agricultural seasons. Voucher receipt also leads to large, persistent increases in household agricultural production and market sales, per capita consumption, assets, durable good ownership, and housing improvements
Measuring skills in developing countries by Rachid Laajaj( )

5 editions published between 2017 and 2018 in English and Undetermined and held by 64 WorldCat member libraries worldwide

Measures of cognitive, noncognitive, and technical skills are increasingly used in development economics to analyze the determinants of skill formation, the role of skills in economic decisions, or simply because they are potential confounders. Yet in most cases, these measures have only been validated in high-income countries. This paper tests the reliability and validity of some of the most commonly used skills measures in a rural developing context. A survey with a series of skills measurements was administered to more than 900 farmers in western Kenya, and the same questions were asked again after three weeks to test the reliability of the measures. To test predictive power, the study also collected information on agricultural practices and production during the four following seasons. The results show the cognitive skills measures are reliable and internally consistent, while technical skills are difficult to capture and very noisy. The evidence further suggests that measurement error in noncognitive skills is non-classical, as correlations between questions are driven in part by the answering patterns of the respondents and the phrasing of the questions. Addressing both random and systematic measurement error using common psychometric practices and repeated measures leads to improvements and clearer predictions, but does not address all concerns. The paper provides a cautionary tale for naive interpretations of skill measures. It also points to the importance of addressing measurement challenges to establish the relationship of different skills with economic outcomes. Based on these findings, the paper derives guidelines for skill measurement and interpretation in similar contexts
Subsidies and the African green revolution : direct effects and social network spillovers of randomized input subsidies in Mozambique by Michael R Carter( )

5 editions published in 2019 in English and held by 58 WorldCat member libraries worldwide

The Green Revolution bolstered agricultural yields and rural well-being in Asia and Latin America, but bypassed sub-Saharan Africa. We study the first randomized controlled trial of a government-implemented input subsidy program (ISP) in Africa. A temporary subsidy for Mozambican maize farmers stimulates Green Revolution technology adoption and leads to increased maize yields. Effects of the subsidy persist in later unsubsidized years. In addition, social networks of subsidized farmers benefit from spillovers, experiencing increases in technology adoption, yields, and beliefs about the returns to the technologies. Spillovers account for the vast majority of subsidy-induced gains. ISPs alleviate informational market failures, stimulating learning about new technologies by subsidy recipients and their social networks

Disasters, Climate Change and Economic Development in Sub-Saharan Africa Lessons and Directions by Ajay Chhibber( )

2 editions published in 2008 in English and held by 7 WorldCat member libraries worldwide

This paper explores the links among natural disasters, climate change and economic development, and attempts to outline a framework for considering these links. The paper summarises the limited knowledge of the long-term economic impact of natural disasters. Drawing links among disasters, resource management, conflicts and other transmission channels is a necessary condition to develop an appropriate response. The paper argues that African governments along with their development partners need to develop a more robust adaptation and response capability to disasters as part of development planning. The paper makes the case for more market-based financing mechanisms than have been used hitherto and an emphasis on forecasting research. It also argues for more work on the links between climate change and disasters and a new way of looking at disaster resilience as a continuum to development strategy
Agricultural, financial and behavioral changes on the path to sustainable technology adoption in rural Mozambique by Rachid Laajaj( )

2 editions published in 2012 in English and held by 3 WorldCat member libraries worldwide

This dissertation builds on a project implemented in the Manica province in Mozambique. The project combines voucher subsidies for an improved seeds and fertilizer package, with an intervention that offers a financial education that encourages the opening of savings accounts and a 50% match on savings between harvest and the planting season. Both the agricultural and the financial intervention are randomized in order to evaluate their impact and their complementarity. The first essay of this dissertation analyzes the impact on maize production of receiving a voucher that offers a subsidy on an improved maize seeds and fertilizer .We found that only 28% of the farmers who were offered the subsidy used the content of the package for their maize production and that the average impact on production is not significant. We also find important heterogeneity with the farmers who have more prior experience with fertilizer and use irrigation benefiting more from the subsidy. The second essay uses a poverty trap model and simulation with dynamic optimization to decompose the channels through which Matched Savings can contribute to a long-term reduction in poverty. In the empirical section, we find that the Matched Savings has increased the proportion of participants who hold a savings account by 20 percentage points, and increased their formal savings 2.7 times more than the encouragement to save, follows it. This increase in formal savings mostly comes from a reduction in informal savings. The third essay offers a new theoretical model, based on the psychology literature on cognitive dissonance and time discounting, which explains how the poor can close their eyes on the future in order to reduce the distress that is caused by the anticipation of future poverty. The predictions of the model are tested empirically with each one of the two interventions of the Mozambican experiment. We find that both the agro-input subsidy treatment and the Matched Savings treatment resulted in a significant increase in the beneficiaries' planning horizon. It provides a new analysis of the reasons behind the apparent time inconsistencies of individuals, and the first empirical evidence of the endogenous determination of time preference
Subsidies and the Persistence of Technology Adoption Field Experimental Evidence from Mozambique by Michael Carter( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

We report the results of a randomized experiment testing impacts of subsidies for modern agricultural inputs in rural Mozambique. One-time provision of a voucher for fertilizer and improved seeds leads to substantial increases in fertilizer use, which persist through two subsequent agricultural seasons. Voucher receipt also leads to large, persistent increases in household agricultural production and market sales, per capita consumption, assets, durable good ownership, and housing improvements.Consistent with learning models of the adoption decision, we find positive treatment effects on farmers' estimated returns to the input package. We also document positive cross-household treatment spillovers: one's own fertilizer use rises in the number of social network members receiving vouchers. Our findings are consistent with theoretical models predicting persistence of impacts of temporary technology adoption subsidies, in particular due to learning effects
Corrupción, competencia política y desarrollo social by Johann Oswaldo Salgado Ríos( )

1 edition published in 2016 in Spanish and held by 1 WorldCat member library worldwide

El presente trabajo explora la relación que existe entre la competencia política y los niveles de corrupción. En particular se quiere analizar cuál es el impacto que tiene la competencia política nacional sobre el nivel de corrupción municipal. A su vez, se quiere estudiar el efecto que tiene la corrupción sobre las variables de salud y educación, las cuales pueden determinar el desarrollo social de un municipio. Esto se realizará a través de la estimación de un modelo de variables de conteo exponencial instrumentado, el cual resulta ser novedoso para este tipo de investigaciones, dado que la mayoría de trabajos empíricos referentes a la corrupción se basan en índices que capturan la percepción de esta, más no en el número de casos de corrupción presentados ante la autoridad competente. Con el fin de llevar a cabo esto, se cuenta con datos brindados por la Procuraduría General de la Nación y el Centro de Estudios de Desarrollo Económico (CEDE). La hipótesis de esta investigación, basada en una revisión de literatura nacional e internacional, es que a medida que aumenta el nivel de competencia política, caen los niveles de corrupción. Con base en los resultados obtenidos, se encontró que la hipótesis planteada se cumple y adicional a esto, se encuentra que la corrupción tiene un efecto negativo sobre la provisión de los servicios de salud y educación
Three essays on cooperation and water conservation : behavior, incentives, and institutions by José David López Rivas( )

1 edition published in 2019 in English and held by 1 WorldCat member library worldwide

This dissertation studies pecuniary and non-pecuniary incentives to promote pro-environmental behaviors in Colombia. In particular, water conservation in households. It includes three essays in which I use experimental, quasi-experimental, and observational methods to analyze the response of the households to different incentives and institutional environments. First, I analyze the effects of use over-price to punish excessive water use. Second, I design and carry out a randomized field experiment using a normative message with social comparisons to promote savings in those who receive it and in their neighbors. Finally, I analyze the motivations that underlie the behavior of the household when they are exposed to the normative message

The paradox of equality policies and meritocracy in female leadership by Lina Marcela Ramírez Leguizamón( )

in English and held by 1 WorldCat member library worldwide

This paper examines whether women leaders behave differently when they believe they are elected by a gender quota or by merit and if their behavior is affected by group gender composition. We conduct a laboratory experiment in which participants decide whether to invest or not in a project that presents coordination failures. Leaders can send a risky signal (their investment) to persuade the other members of their group to invest in the project. The group can attain the cooperative equilibrium if the leader is followed. We provide experimental evidence that when investing is costly, the behavior of women leaders is affected by both the way they are elected and the gender composition of their group. We find that gender quotas do not have a significant effect on cooperation but meritocracy triggers selfish attitudes of female leaders when they face all-male or mixed gender followers, undermining cooperation. We argue that group identity may be the underlying explanation of all our findings. When investing represents a social dilemma, leaders elected by merit don't identify themselves with their followers, they believe they are superior and reduce their investment. However, gender identity seems to offset this behavior and reconnect leaders with followers, as the negative effect of meritocracy does not hold when female leaders are facing female followers
Títulos de propiedad como determinantes de regímenes de comportamiento ante choques covariados by Freddy Felipe Parra Escobar( )

1 edition published in 2016 in Spanish and held by 1 WorldCat member library worldwide

Este artículo analiza si los derechos de propiedad y el tamaño de la tierra determinan los mecanismos de respuesta que toman los hogares tras un choque. En particular identifica si las medidas tomadas por un hogar expuesto a la ola invernal ocurrida entre 2010 y 2011 en Colombia fueron diferentes en función de la posesión de títulos de propiedad y el tamaño de la tierra. Para el análisis, se dispone de una encuesta longitudinal que permite observar la situación de los hogares antes y después de ocurrido el fenómeno climático. Empleando técnicas de estimación de umbrales se encuentra que hogares con títulos de propiedad, posesión de tierras superior a 2,13 hectáreas y que hayan estado expuestos a un desastre natural provocado por el incremento en lluvias son más propensos a tomar un crédito. Por otro lado hubo reducción en el acervo de activos de hogares expuestos al choque de manera severa, aunque la disminución fue mayor para hogares con estructura de propiedad informal y poca cantidad de tierra

Análisis del impacto del programa de transferencias monetarias condicionadas Familias en Acción sobre el embarazo adolescente by Luisa Fernanda Cardona Rojas( )

1 edition published in 2017 in Spanish and held by 1 WorldCat member library worldwide

This paper analyzes the effect of the Conditional Cash Transfer (CCT) Program Familias en Acción, in its second phase, on teenage childbearing in Colombia. For this purpose, we use the Fuzzy Regression discontinuity design and we instrument by the eligibility in the program which is defined by the SISBEN Poverty index (Information System of Potential Beneficiaries of Social Programs in Colombia). The results suggest that the effects of FA on teenage childbearing depend on the level of exposure to the program. At low levels, participation in the program increases the likelihood of a woman having teenage childbearing. However, as households stay longer in FA, the effect is neutralized until after a certain exposure threshold the effect is reversed. In order to carry out this work, the administrative data of the Monitoring and Evaluation System of Families in Action (SIFA) and the SISBEN census data for 2004-2007 and 2008-2010 are used
Three essays on dishonesty and corruption by Ruth Yamilett Guillén Salas( )

1 edition published in 2019 in English and held by 1 WorldCat member library worldwide

"This dissertation is made of three essays. In each of them, I present a study related to dishonest conducts that economic agents can develop in the contexts of public administration, business, or academic environments. Through behavioral and experimental tools, I evaluated the incidence of some factors, such as a variation in the economic environment, personal traits, and weak institutions, on the occurrence of dishonest acts. Also, I evaluated the effectiveness of some institutions to discourage opportunistic behaviors when managing public funds. In Chapter 1, with Juan Camilo Cárdenas, we study whether individuals who are interested in initiating a business in Colombia where dishonest practices are perceived as common in business are ethically different from those who prefer other career paths. We evaluated differences in the level of acceptance of rule-breaking in civil and academic contexts?among undergraduates with entrepreneurship preferences and non-entrepreneurship preferences. Also, we evaluated the seriousness that they linked to different kinds of transgressions. In Chapter 2, I study, through a laboratory experiment, how voluntary contributions to finance the production of a good distributed by a state agent evolve in a context of weak accountability. Also, I evaluate the effects of three institutions, based on binding and non-binding communication rather than pecuniary punishments to promote contributions and reduce misappropriation, within this scenario of weak accountability. In Chapter 3, I experimentally address whether a sudden increase of State resources, around those who can potentially assign them improperly or capture them privately, increases the likelihood of economic agents to behave corruptly. The findings of this dissertation contribute to improve our understanding of the occurrence and persistence of dishonest acts. Furthermore, they contribute to the design of policies to discourage dishonest and corrupt behaviors."--Tomado del Formato de Documento de Grado
Prison overcrowding and recidivism : evidence from an expansion in prison capacity by Santiago Tobón Zapata( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

I investigate the relationship between prison overcrowding and recidivism by focusing on the rearrest rates of inmates exposed to different levels of overcrowding. To do so, I exploit an exogenous variation in overcrowding levels suffered by inmates resulting from an expansion of about 25 thousand slots in the Colombian penitentiary systm. Since 2004 and up to 2013 some prisons were expanded and others built. Results for the intention to treat show that inmates at treated prisons are between 0.6 and 1 percentage point less likely to be rearrested the same calendar year of release (i.e. 30% to 50% relative to the average rearrest rate). The local effect for inmates who actually saw a change in overcrowding shows that a one standard deviation increase in the overcrowding level (i.e. 67.1 percentage points or 94% relative to the mean), causes an increase of 1.4 percentage points in the likelihood of rearrest in the same calendar year of the inmate's release (i.e. 70% relative to the average rearrest rate). This effect seems to be driven by a limitation to enroll into rehabilitation programs
Eficiencia y tamaño del predio agrícola en Colombia by Santiago Ospina Sierra( )

1 edition published in 2017 in Spanish and held by 1 WorldCat member library worldwide

Este trabajo analiza el efecto que tiene el tamaño del predio agrícola sobre la productividad de la tierra y la productividad laboral para las regiones que cubre la ELCA. Por medio del seguimiento a 2.099 hogares en las rondas de 2010 y 2013, se plantea un modelo de primeras diferencias que controla por características no observables de los hogares y reduce parcialmente el sesgo negativo encontrado en trabajos anteriores. Los resultados muestran una relación en forma de U entre el tamaño del predio y la productividad, donde aumentos de una hectárea en la diferencia del tamaño de la tierra entre las dos rondas, disminuyen el rendimiento de la tierra en 19,4 puntos porcentuales. La relación se vuelve positiva a partir de 44,54 hectáreas. Se incluye un canal de análisis que mide el efecto del nivel de mecanización de los hogares y muestra que el aprovechamiento de economías de escala derivadas del uso de maquinaria a medida que aumenta el tamaño del predio tiene efectos positivos sobre la productividad de 1,7 puntos porcentuales. El bajo nivel de mecanización que tienen los hogares es la principal razón por la que el efecto del canal no es más grande
