| Resumen Este trabajo analiza la calidad en la producción de leche y su relación con la genética del rebaño. El marco analítico es un modelo de producción multi-output en el que la calidad de la leche se considera como un output del proceso productivo. El modelo propuesto abre la posibilidad del tratamiento empírico de la calidad y la genética mediante el uso de funciones distancia. En la parte empírica del trabajo se usa un panel de datos de 96 explotaciones lecheras asturianas que contiene índices genéticos del rebaño. Palabras clave: leche, calidad, genética, multi-output, función distancia. Abstract In this paper we analyze the influence of genetics on milk quality. For that purpose, we use a multi-output production model in which milk quality is... |

| Farm planning generally focuses on optimal diversification with respect to risk and uncertainties, where the risk-management strategies combine production, marketing, financial and environmental responses of the production of farm firm. In this study an empirical examination of farm diversification has been carried out from a sample of farms in Eastern Norway in which four measures of diversification (indices) were defined to incorporate the risk and uncertainties in relation to farm production (total) income. Using these four alternative measures of diversification and panel-data techniques, it has been shown that larger farms are more diversified, and when there is productive location and access to labour the farmers have a greater incentive to spread... |

| This paper investigates the empirical magnitude of climate conditions on tourist flows in Tuscany, exploring the use of a fine spatial scale analysis. In fact, we explore the use of an 8-year panel dataset of Tuscany’s 254 municipalities, examining how tourist inflows respond to variation in local weather conditions. In particular, as the area enjoys a fairly mild Mediterranean climate, our analysis focused on temperature extremes at key times of the tourist season, i.e., on maximum summer temperature and minimum winter temperature. Separate analyses are conducted for domestic and international tourists, so as to test the differences in the preferences among these distinct groups (or types of demand). Estimation results show the impact of climate change on... |

| Consumption and income have both grown rapidly in Taiwan over the past forty years, with younger birth cohorts experiencing faster growth. The long upward trend in consumption presents a strong challenge to the consumption smoothing predictions of the Permanent Income Hypothesis. We investigate the extent to which consumption theory can account for this trend in an environment where a large majority of households have high savings rates. Household survey data from 1976-96 are used to estimate dynamic pseudo-panel models with inter-cohort heterogeneity. We evaluate the impacts on consumption of migration, mortality, household composition, liquidity constraints, unanticipated aggregate shocks, hyperbolic discounting, habit formation and precautionary saving.... |

| This paper analyzes the various contributions made in the economic literature that influence climate change vulnerability. We try to create conceptual order and transparence in the contributions identifying the assumptions and constraints that each school has introduced into academic debate and practical application. We analyze the conceptual framework that articulates the debate, review the theoretical approaches developed in the literature identifying the object of analysis and the basics of each theory, so that the real model implications are established in each case study. From this scheme we derive a clarifying proposal for organizing theoretical discourse. We specifically focus on the theoretical assumptions underlying each model. We conclude with... |

| This paper aims at analysing the effect of democratic institutions on environmental quality (carbon dioxide per capita, sulfure dioxide per capita) and at identifying potential channel transmissions. We use panel data from 1960 to 2008 in 122 developing and developed countries and modern econometric methods. The results are as follows: Firstly, we show that democratic institutions have opposite effects on environment quality: a positive direct effect on environment quality and a negative indirect effect through investments and income inequality. Indeed, democratic institutions attract investments that hurt environment quality. Moreover, as democratic institutions reduce income inequality, they also damage environment. Secondly, we find that the direct... |
