Climate change adaptation and its effects on the economy of the rural Mexican household food producers

This article analyzes the possible impacts of the climate change (CC) and its adaptation measures on the maize trade surplus/deficit, on the production, and on the real income of households established in rural Mexico. The analysis is based on an Applied and Microeconomic General Equilibrium Model and on the estimates of the direct effects of CC on maize yields obtained from the related literature. The results show that climate change will reduce the real rural income by 6.23% and will affect corn production to the extent that the area will change from being a surplus to a deficit. In addition, it is found that while the adaptation measures analyzed in the paper will help to reduce the negative effects of the phenomenon, they will not completely eliminate them.   Adaptación al cambio climático y sus efectos en la economía de los hogares rurales mexicanos productores de alimentos ABSTRACT En este artículo, se analizan los posibles impactos del Cambio Climático (CC) y de sus medidas de adaptación en el superávit/déficit comercial del maíz, en la producción y los ingresos reales de los hogares establecidos en la zona rural de México, a partir de un Modelo de Equilibrio General Aplicado y Microeconómico, y de estimaciones directas de los efectos del CC en los rendimientos del maíz obtenidas de la literatura relacionada. Los resultados encontrados muestran que el cambio climático reducirá el ingreso real rural en 6.23% y que afectará, en mayor medida, a la producción de maíz, al grado que la zona pasará de ser superavitaria a deficitaria. Además, se obtuvo que, si bien las medidas de adaptación analizadas ayudarán a reducir los efectos negativos del fenómeno, estas no los eliminarán totalmente

Estimating shadow prices in economies with multiple market failures.

Approaches to the estimation of shadow prices generally assume that all but one market function correctly. However, multiple market failures are common in developing countries. We present a theoretical model and an empirical strategy to estimate the shadow price of a subsistence good in an economy where labor markets fail. Our results show that: 1) among subsistence producers, the shadow price of this good must be greater than or equal to the market price, and equal to it for surplus growers; and 2) current methods create biases when the otherwise-perfect-markets assumption is violated. The propositions are tested using a representative survey for rural Mexico. We find that the shadow wage is below that of the market (MXN $93.2/day vs. MXN$132.3/day), and that the shadow price for subsistence corn is over ten times greater than its market price (MXN $32.37/kg vs. MXN$3.19/kg). Unbiased shadow price estimates for subsistence goods help to overcome the limitations of current income poverty measures: their overestimation of the purchasing power of subsistence households and their underestimation of the value of subsistence goods. In rural Mexico, current practice underestimates the population in food poverty by 2%; an additional 9% has income above the poverty line yet fail to meet the utilization dimension of food security
