Value chain research and development: The quest for impact

Jason Donovan (2023, [Artículo])

Motivation: For decades, governments, donors, and practitioners have promoted market-based development approaches (MBDA), most recently in the form of value chain development (VCD), to spur economic growth and reduce poverty. Changes in approaches have been shaped by funders, practitioners and researchers in ways that are incompletely appreciated. Purpose: We address the following questions: (1) how have researchers and practitioners shaped discussions on MBDA?; and (2) how has research stimulated practice, and how has practice informed research? We hypothesize that stronger exchange between researchers and practitioners increases the relevance and impact of value chain research and development. Methods and approach: We adopt Downs' (1972) concept of issue-attention cycles, which posits that attention to a particular issue follows a pattern where, first, excitement builds over potential solutions; followed by disenchantment as the inherent complexity, trade-offs, and resources required to solve it become apparent; and consequently attention moves on to a new issue. We review the literature on MBDA to see how far this framing applies. Findings: We identify five cycles of approaches to market-based development over the last 40 or more years: (1) non-traditional agricultural exports; (2) small and medium enterprise development; (3) value chains with a globalization perspective; (4) value chains with an agri-business perspective; and (5) value chain development. The shaping and sequencing of these cycles reflect researchers' tendency to analyse and criticize MBDA, while providing limited guidance on workable improvements; practitioners' reluctance to engage in critical reflection on their programmes; and an institutional and funding environment that encourages new approaches. Policy implications: Future MBDA will benefit from stronger engagement between researchers, practitioners, and funders. Before shifting attention to new concepts and approaches, achievements and failures in previous cycles need to be scrutinized. Evidence-based practice should extend for the length of the issue-attention cycle; preferably it should arrest the cycling of attention. Funders can help by requiring grantees to critically reflect on past action, by providing “safe spaces” for sharing such reflections, and by engaging in joint learning with practitioners and researchers.

Los valores egocéntricos desfavorecen el comportamiento pro-ambiental de los guías de buceo en el Parque Nacional Arrecifes de Cozumel

The egocentric values disfavor the pro-environmental behavior of the diving guides in the Arrecifes de Cozumel National Park

SANDRA BEATRIZ CHAN CHAN AURORA IRMA MAYNEZ GUADERRAMA ALEJANDRO LUIS COLLANTES CHAVEZ COSTA LUIS CARLOS SANTANDER BOTELLO (2019, [Artículo])

El buceo como actividad turística ha potencializado la economía, pero también ha impactado a las zonas arrecifales. Durante el buceo, el guía es el principal actor en la protección del ambiente marino, pues en él recae el control de las actividades realizadas por los buzos. En esta investigación se analiza la relación entre los valores, creencias y normas sobre la intensión que tienen los guías de buceo por conservar el ambiente marino. El estudio se abordó a través de la teoría de Valores, Creencias y Normas (VCN) y fue analizado a través de modelos de ecuaciones estructurales con el método de Partial Least Squares. Se confirma la causalidad del modelo VCN y se identifica que la valoración de los recursos marinos podría estar influenciada por los valores egocéntricos lo cual no permitió la concepción de una intención de un comportamiento que sea favorable.

Diving as a touristic activity has boosted the economy, but it has also impacted the reef areas. During this activity, the guide is the main actor in the protection of the marine environment, since he has the control of the activities carried out by the divers. This research analyzes the relationship between values, beliefs and norms about the intension of diving guides to preserve the marine environment. The study was approached through the theory of Values, Beliefs and Norms (VCN) and was analyzed through structural equation models with the method of Partial Least Squares. The causality of the VCN model is confirmed, and it is identified that the valuation of the marine resources could be influenced by the egocentric values, which did not allow the conception of an intention of a favorable behavior.

La relación entre el crimen y ciclo económico en México: un enfoque espacial

Ricardo Masahiro Solis Ichien (2021, [Tesis de maestría])

En este trabajo se analiza la influencia del ciclo económico sobre los niveles de crimen en México desde el marco conceptual de la teoría de Cantor y Land (1985), los cuales distinguen el efecto de oportunidad y motivación criminal. Se presenta el análisis para el caso mexicano y se evalúa empíricamente el modelo de Cantor y Land para las 32 entidades federativas con datos trimestrales del 2010 a 2019. Utilizando un modelo econométrico que incorpora la interacción espacial en la tasa de crímenes y en el término de error, así como su rezago temporal, al que se le denomina como modelo espacial autorregresivo con errores autorregresivos de orden 1 (SARAR (1,1)) dinámico, se evalúa el modelo para siete tipos de crímenes: homicidios dolosos, secuestros, extorsiones, robo a negocios, robo a casa-habitación, robo de vehículo y robo a transeúnte. Los resultados muestran que se verifica la teoría de Cantor y Land (1985) para cuatro de los siete tipos de delitos. Los robos analizados se caracterizan como robos de necesidad y robos de especialización. Se encuentra evidencia del comportamiento espacial de la actividad criminal donde algunos delitos tienen un efecto regional y otros se concentran.
