| Resumen: |
This paper studies the effects of drought shocks in a vulnerable environment - the Brazilian Semi-Arid. We analyze the impact of drought shocks, measured as deviations from long-run historical averages, on agricultural outcomes in a region that suffers recurrently from drought. After controlling for municipality and year fixed effects, we use weather shocks to exactly identify outcomes. Our benchmark results show substantial effects on the loss of crop area and on the value of agricultural output, as well as on crop yields. As we investigate distributional effects, our results show that crops related to familiar agriculture suffer more from drought shocks. We follow our investigation by testing heterogeneity effects and show that adequate water provision and maintenance of forest cover help in reducing the impact of drought shocks. |

| Resumen: |
El conjunto de actores de los mercados financieros a nivel mundial están demandando de forma creciente que la información financiera de las empresas se vea integrada con información de carácter ambiental, social y de gobierno corporativo. Las agencias de calificación de la sostenibilidad surgen en los mercados como oferentes de dicha información, desarrollando sus propias herramientas de medición y evaluación de los criterios financieros, ambientales y de gobernanza (FASG). El objetivo de este artículo es poner de manifiesto la función impulsora y modeladora que están realizando estas agencias en el análisis de la sostenibilidad corporativa, sus metodologías de evaluación y los criterios que utilizan, constatando que están potenciando el desarrollo de la inversión socialmente responsable (o inversión sostenible, o inversión con criterios ASG), y de las finanzas sostenibles, tanto por ofertar bases de datos de criterios FASG, como por la elaboración de índices bursátiles de sostenibilidad que sirven de benchmarking para los fondos de inversión con criterios de sostenibilidad. Sin embargo, por ahora, este impulso no está impactando en la innovación hacia modelos de negocios sostenibles. |

| Resumen: |
Logistics and transport increasingly play a pivotal role in international trade relations. The Logistics Performance Index (LPI) measures the on-the-ground efficiency of trade supply chains or logistics performance. The aim of this paper is to propose a data envelopment analysis (DEA) approach to compute a synthetic index of overall logistics performance (DEA-LPI) and benchmark the logistics performance of the countries with LPI. Dealing with the six dimensions of LPI, the proposed approach uses DEA as a tool for multiple criteria decision making (MCDM). Furthermore, the paper also analyses the potential differences observed when using different variables, namely income and geographical area. Our findings suggest that the logistics performance depends largely on income and geographical area. High income countries are in the group of best performers, which is highly dominated by the EU. |

Qual VAR revisited: Good forecast, bad story |

| Resumen: |
Due to the recent financial crisis, the interest in econometric models that allow to incorporate binary variables (such as the occurrence of a crisis) experienced a huge surge. This paper evaluates the performance of the Qual VAR, originally proposed by Dueker (2005). The Qual VAR is a VAR model including a latent variable that governs the behavior of an observable binary variable. While we find that the Qual VAR performs reasonable well in forecasting (outperforming a probit benchmark), there are substantial identification problems even in a simple VAR specification. Typically, identification in economic applications is far more difficult than in our simple benchmark. Therefore, when the economic interpretation of the dynamic behavior of the latent variable and the chain of causality matter, use of the Qual VAR is inadvisable. |

| Resumen: |
In recent years, the surge in China’s CO2 emissions has caused increasing international concern. In this paper, we investigate whether and when the turning point in China’s CO2 emissions would occur. A simple yet powerful neoclassical Green Solow model (GSM) is utilized herein as the main forecasting tool. To verify the capability of this framework to address China’s economy, a key prediction of the GSM "the convergence in per capita CO2 emissions across Chinese provinces" is empirically verified. By assigning reasonable values to the GSM’s key parameters, the trajectories of total CO2 emissions are projected for the three regions of China and the whole country. The forecast results show that, under the benchmark scenario, China’s total CO2 emissions would peak around the year 2047. According to the sensitivity analysis, carbon efficiency is the most important determining factor for whether a turning point in total CO2 emissions may occur. |
