Project Goal: The main objective of the project was to analyze the specialty coffee market in Mexico with an emphasis on factors that affect supply and demand. The methodology consisted of a mixed research approach, which includes the review of secondary information sources (scientific articles, reports, databases, evaluations, among others), in addition to collecting data through direct surveys of coffee producers. managers of marketing companies, representatives of cooperatives and coffee shop owners, among other key players in the coffee value chain in Mexico.
Current Stage: Finalized
Project Goal: We investigate how external social ties, that is, social ties with individuals outside the borrowing group, determine loan repayments of individual borrowers in joint liability group lending. We measure the resources in external ties in terms of the informal risk insurance arrangement they embed. The ties borrowers have with individuals outside the group and the informal risk insurance arrangement they represent, help to survive in general, and repay their loans in particular.

This study models the purchasing behavior of specialty coffee by 114 coffee shops across 15 cities in nine states in Mexico. Simple and multilevel mixed-effects logistic models are tested. Our models extend the framework used in prior research. We model the purchase of specialty coffee as a function of: (a) material attributes, (b) symbolic attributes, (c) coffee shop characteristics, (d) profile of the coffee shop’s owner, and (e) socio-economic variables of the cities where the coffee shops were located. Overall, our results are consistent with expectations developed from the coffee literature. That is, the likelihood of purchasing specialty coffee increases when: coffee’s aroma drives the purchase, coffee purchased is from the state of Oaxaca, the coffee shop has a value-added business model, the coffee shop is diversified selling both ground coffee and coffee drinks, the coffee shop owner’s knowledge on coffee supply chain activities is high, and the coffee shop is located in a city with a higher education index. In contrast, the likelihood of purchasing specialty coffee decreases when a coffee professional tastes the coffee before the purchase, when coffee shops are not given the opportunity to roast their own coffee, and in coffee shops located in larger cities. Overall, our research suggests that the specialty coffee niche in Mexico has some elements required for this segment to transition from a supply chain approach to a value-based supply chain approach. This might be particularly beneficial for smallholder coffee growers, who despite several constraints contribute to the sustainability of coffee supply chains.

BACKGROUND The relationships between soil and coffee beans variables were evaluated and then the influence of bean composition on cup quality attributes was computed by means of relation studies. A total of 139 coffee and soil samples were collected directly from the same number of coffee plantations in Chiapas, Mexico. RESULTS In the elemental composition, only phosphorus, potassium, calcium, and copper in coffee beans had a significant (P < 0.05) relationship with the content of the same elements in soil. The level of macro‑ and microelements in the coffee bean affected some of the cup quality attributes, but variables such as texture, titratable acidity, and pH of water in soil had a major influence on those attributes. Caffeine, trigonelline, and 5‐caffeoylquinic acid in green coffee beans also had a significant influence (P < 0.05) on the sensory attributes of the beverage. CONCLUSION The elemental composition of soil and coffee beans was important in explaining the cup quality attributes, but the most important variables influencing the sensory quality of coffee were altitude of plantations and moisture of coffee beans. © 2020 Society of Chemical Industry

The objective was to determine the effects of replacing binding agents with commercial low‐calorie sweetener solutions on the physicochemical and temporal dominance of sensations in amaranth bars. Five baked amaranth bar formulations (Swetener‐Solution‐Formulated Amaranth Bars: SSFABs) were prepared using solutions of: erythritol, sucralose, steviol and two sucrose concentrations (50% and 25%). A commercial bar (COMM) was used as a control. Proximal, pH, water activity, texture and colour were measured. Temporal Dominance of Sensations (TDS) was used to determine dominant attributes in time. In general, SSFABs bars showed a higher moisture, ash and protein content compared to COMM. Carbohydrates and total crude fat were lower in SSFABs than in COMM. Dominant attributes were crispy, dry, sweet, and amaranth. Erythritol formulation was similar to the commercial bar in terms of maximum dominance rate. Replacement of binding agents impacted on the evolution of dominant attributes in amaranth bars.

We investigate how external social ties, that is, social ties with individuals outside the borrowing group, determine loan repayments of individual borrowers in joint liability group lending. We measure the resources in external ties in terms of the informal risk insurance arrangement they embed. The ties borrowers have with individuals outside the group and the informal risk insurance arrangement they represent, help to survive in general, and repay their loans in particular. The risk of losing these ties increases the willingness to repay loans, that is, these ties can be regarded as a form of collateral to stimulate loan repayment. The extent to which these external ties are effectively pledged as collateral depends on the extent to which social networks of group members are overlapping: the more borrowers’ networks of external ties overlap (referred to as information channels), the higher the risk of losing the informal risk insurance arrangement in case of non-repayment. We use data from 802 mapped social networks of borrowers’ internal and external ties from a microfinance institution in Mexico. We find that group borrowers with external ties, representing a strong informal risk insurance arrangement while at the same time being information channels, have lower repayment problems

Actualmente el emprendimiento tiene gran importancia, tanto para emprendedores como para instituciones públicas y privadas. La creación de empresas se vuelve un tema de investigación importante. El objetivo de este trabajo es determinar las diferencias que existen entre la manera de crear las microempresas. El trabajo se desarrolló en la comunidad de Santa Bárbara Almoloya con 73 microempresarios. Mediante un cuestionario se levantó la información necesaria y se han podido formar cuatro grupos que se diferencian entre sí, tanto en capitales financiero, social y humano como en motivaciones. Se concluye que los objetivos y el capital financiero son los elementos indispensables para la creación de las microempresas, pero este último pierde su importancia si las personas tienen un nivel de capital social alto. Las implicaciones de este trabajo sirven para los interesados en la promoción del emprendimiento en el medio rural, como instituciones de microfinanzas (IMF), gobierno e investigadores, así como futuros emprendedores.

La comercialización de cafés diferenciados ha tomado una gran relevancia debido a que es una opción para los pequeños productores para acceder a mercados internacionales y mejorar su bienestar económico. Lo anterior requiere de nuevas estrategias para responder a los cambios en la demanda a lo largo de la cadena de abastecimiento. Mediante el desarrollo de un estudio de caso en el que se incluye un total de diecisiete entrevistas, diez a productores, cinco entrevistas aplicadas a los representantes de cada cooperativa, una al representante de la empresa Integradora INCAFESAM, y una al representante de la empresa Malongo, el presente estudio muestra como las prácticas colaborativas adoptadas permiten ser una solución para lograr una reducción en los costos de transacción y mayor coordinación en la cadena de abastecimiento del café de la región de Córdoba, Veracruz. La investigación se llevó a cabo entre los meses de septiembre de 2015 y mayo de 2016. Los resultados obtenidos muestran que, la prácticas de estandarización, certificación y aprovisionamiento asociado han contribuido en la reducción de los costos de transacción tales como de información sobre la cantidad de abastecimiento, calidad del producto, y costos por monitoreo y de negociación. Por otra parte, la práctica intercambio de información ha permitido mejorar la coordinación entre los miembros de la cadena de abastecimiento lo que resulta en una mejor planeación y disponibilidad de producto con base en la calidad requerida en el mercado.
