Irving Fisher's theory on time preference in the 1930s arguably influenced the analysis of agents' current behavior with respect to future outcomes. By suggesting linear discount rates implying rational and self-interested motives of agents, Fisher substantiated neoclassical economic thinking. However, Fisher's notion of time preference, the choice between present and future enjoyment that actually integrates a psychological discounting component has not received similar attention in the scholarly literature. This paper aims at closing this gap. It empirically examines agent behavior under uncertain conditions culminating from natural shocks, and differentiates the psychic from the physical component. To empirically test Fisher's notion of time preference,... |

Los productos pesqueros se han catalogado en general como alimentos sensibles desde el punto de vista del riesgo alimentario y dada la aparición de entidades mórbidas de origen pesquero que pueden definirse como “emergentes”, se ha considerado necesaria una actualización de la información científica disponible. Ello abarca los riesgos que para los consumidores nacionales pueden tener potencialmente un grupo de alimentos derivados de animales acuáticos, los cuales luego de acondicionados, elaborados o transformados tecnológicamente, empacados e identificados se vuelcan al mercado como productos pesqueros. Para ello, teniendo en cuenta las directrices en materia de análisis de riesgo y a la información disponible se efectuó este análisis descriptivo de la... |

The paper presents the results of the sociological survey and expertise describing the factors of risk reduction and increase of the level of trust in contract relations in food networks. The level of contract discipline is analyzed. It is shown that the insufficient rate of development of the institution of trust restricts the liberty of action for companies operating in a food network, deprives them of the opportunity to achieve the local optima and provides no grounds for setting their economic behavior sure-footed standards. Following the sociological survey the dynamics and structure of the transaction costs in food networks are displayed along with the specific features of their accounting in the companys operations. An expertise of the most... |

The aim of this paper is to evaluate the effect of rainfall and agricultural shocks on consumption growth in Madagascar. We are also interested in the impact of local endowments in infrastructures and social services on consumption growth. To achieve this goal, a micro model of household consumption growth is estimated thanks to household panel data collected by the Reseau des Observatoires Ruraux (ROR) between 1999 and 2004. Additional data sources include the 2001 communes census organized by the Ilo program of Cornell University. Altogether these different data sources make an unusually rich data set, at least when considered with developing country standards. We use panel data fixed effect estimation technique to remove unobserved household and... |

Poverty has always been studied in a world of certainty. However, if the aim of studying poverty is not only improving the well-being of households who are currently poor, but also preventing people from becoming poor in the future, a new forward looking perspective must be adopted. For thinking about appropriate forward-looking anti-poverty interventions (i.e. interventions that aim to prevent or reduce future poverty rather than alleviate current poverty), the critical need then is to go beyond a cataloging of who is currently poor and who is not, to an assessment of households’ vulnerability to poverty. This study analyses a panel dataset on a representative sample of 150 rural households interviewed in 2007 and 2008 in the Amathole District... |

Global molluscan aquaculture production is continuously increasing, dominated by five species, among which the Pacific cupped oyster, Crassostrea gigas, predominates. Hatchery production is accompanying this increase to assist consistent availability of juveniles for restocking, fishery enhancement, genetic improvements as well as for species diversification. Hatchery development contributes significantly to the demand for international transfers of live molluscs; a consequence of which pathogen transfer via transfer of live molluscs is currently recognised as a major cause of epizootic disease outbreaks. Diseases are a primary constraint to mollusc aquaculture growth and sustainability, severely impacting socioeconomic development in many countries.... |

Modeling crop yield distributions has been an important topic in agricultural production and risk analysis, and nonparametric methods have gained attention for their flexibility in describing the shapes of yield density functions. In this article, we apply a nonparametric method to model joint yield distributions based on farm-level data for multiple crops, and also provide a way of simulation for univariate and bivariate distributions. The results show that the nonparametric models, both univariate and bivariate, are estimated quite well compared to the original samples, and the simulated empirical distributions also preserve the attributes of the original samples at a reasonable level. This article provides a feasible way of using multivariate... |

Whitemouth croaker (Micropogonias furnieri)has a broad distribution along the Atlantic coast of the Americas, from Mexico to the south of the Province of Buenos Aires, Argentina. At the southern end of distribution, Argentina and Uruguay catch the species with different commercial fleet types bay or creek, coastal and off-shore and modalities of bottom trawling with doors and paired trawling. Maximum catches of both countries, that reached 60,000 t, were registered between 1995 and 1997. After that period a remarkable decrease was observed, specially in Argentina where catches remained at around 6,000 t over a total of 30,000 t for both countries. The commercial fleet was divided in three categories and the total area of study in three subareas: El Salado,... |

Period 1985-2001. A stock assessment of Patagonian hoki of the Southwest Atlantic was carried out by using data from the years 1985-2001. A cohort analysis, fitted with some survey abundance indices was used in an adaptive conceptual framework. Simulation trials were performed to project the evolution of the fishery, to evaluate the risk of over-fish the stock under different exploitation levels, and to estimate Biologically Acceptable Catches (BAC). Both total biomass and spawning stock biomass showed increasing trends resulting from four strong year classes (1993, 1995, 1996 and 1998). Total biomass at the beginning of 2001 was estimated to be 2.5 million tons, and spawning stock biomass at the spawning time (August) was estimated to be around 1.28... |

We present a standard model of financial innovation, in which intermediaries engineer securities with cash flows that investors seek, but modify two assumptions. First, investors (and possibly intermediaries) neglect certain unlikely risks. Second, investors demand securities with safe cash flows. Financial intermediaries cater to these preferences and beliefs by engineering securities perceived to be safe but exposed to neglected risks. Because the risks are neglected, security issuance is excessive. As investors eventually recognize these risks, they fly back to safety of traditional securities and markets become fragile, even without leverage, precisely because the volume of new claims is excessive. Financial innovation can make both investors and... |

A Dunaszigeten 300 anyával működő gazdaság eredményességében kulcskérdés a termelési költségek csökkentése, mindenekelőtt a takarmányozás, az egyéb (áram, tejvizsgálat, bérleti díjak stb.), valamint a munkabérköltségek mérséklése. A bevételi oldalon növekvő jelentőségű – a kecsketej- és gidaértékesítés mellett – egyre nagyobb arányban a sajtértékesítés. A jövőt illetően a kockázati tényezők és a fejlesztési lehetőségek számbavétele, a helyi lehetőségek hasznosítása, s az egészségre kedvező hatású tej és sajt megismertetése a meghatározó. ------------------------------------ The success of the farm using 300 mother goats depended on the reduction of production costs including especially that of fodder and others (electricity, milk... |
