Economic impacts of El Niño southern oscillation: evidence from the Colombian coffee market

El Niño Southern Oscillation (ENSO) is a naturally occurring phenomenon that affects weather around the world. Past ENSO episodes have had severe impacts on the economy of Colombia. We study the influence of ENSO on Colombian coffee production, exports, and price. Our structural econometric specification is consistent with an economic model of the market for Colombian coffee which, in the short run, is characterized by a downward‐sloping demand curve and by a vertical supply curve. We show that El Niño (i.e., positive shocks to ENSO) is beneficial for Colombian production and exports and decreases the real price of Colombian coffee. On the contrary, La Niña (i.e., negative shocks to ENSO) depresses Colombian coffee production and exports and increases price. However, the overall impact of ENSO shocks is small. Both in the short run and in the long run, shocks to international demand for Colombian coffee are more relevant than supply‐side shocks in Colombia in explaining the dynamics of the price of Colombian coffee. Our results suggest that a given coffee price shock can have beneficial, detrimental, or negligible effects on the Colombian economy, depending on its underlying cause. As a consequence, policy responses to coffee price shocks should be designed by looking at the causes of the shocks.     

Indigenous Cosmogony and Andean Architecture in El Alto,Bolivia

This essay applies Bourdieu's analysis of the formation of the ‘scholastic habitus’ in medieval times—elaborated in his 1967 afterword to his French translation of Erwin Panofsky's Gothic Architecture and Scholasticism—to the correspondence between indigenous mental categories and architectural innovation in the Bolivian ‘rebel city’ of El Alto. The principle of homology between mental categories and building layout (rooted in a shared habitus) can be used to interpret one of the most spectacular features of Bolivia's ‘emerging architectures’, known as chalets. The term chalet designates a hybrid structure consisting of a colorful and ornate penthouse and multi‐story dwelling erected on building rooftops. The chalets are architectural forms embedded within an economy of symbolic goods characterized by a ‘dual truth’: they are at once material and symbolic; they perform economic functions while seeking public visibility. The conspicuous lifestyle advertised by the construction of chalets can be understood by reference to the rising social power of the indigenous elites (cholos) dominating the thriving ‘ethnic economy’ of the city. The fraternities of El Alto emerge as the structural equivalent of the scholastic institution that Bourdieu associated with Gothic architecture: they are the site of production of a specific habitus, shared by native urban categories defined by similar residential locations, economic activities and forms of collective organization.     

Public transportation demand in a border metropolitan economy

Empirical research for public transport demand has uncovered numerous interesting commonalities across metropolitan economies. This study examines the demand for municipal bus services over time in El Paso, Texas, USA. El Paso is one of the largest metropolitan economies in the USA located directly adjacent to an international boundary with another country. This study not only models the demand for municipal bus services as a function of traditional variables such as price, income and weather, but also includes regressors designed to measure the potential impacts of cross-border economic conditions on El Paso ridership. Results from a Linear Transfer Function (LTF) modelling approach indicate that rider volumes are affected by domestic as well as international economic conditions in this border metropolitan area.     

Bolivia’s Institutional Transformation: Contact Zones,Social Movements,and the Emergence of an Ethnic Class Consciousness

Over the past two decades, development economics has experienced a shift in focus from standard neoclassical analysis to institutions. While studying economic institutions is indeed important, evaluating their transformation and embeddedness is equally crucial for understanding and improving human wellbeing, especially in countries where market institutions are not fully developed. With that perspective in mind, we consider the importance of culture in the evolution of institutions in Bolivia by combining the concept of contact zones with old institutional economics (OIE). Contact zones refer to daily interactions in social spaces where culture and class meet and negotiate with each other. The contact zone between Bolivians and post-WWII development policies surfaced as an Andean collective memory, allowing for a possibility of social and political autonomy through the creation of an alternative to development, El Buen Vivir.
