| The present study examines family and farm characteristics affecting the choice and the timing of intergenerational farm transfers. Using survey data which are linked to accounting data for 272 farms in Northern Germany, we use a probit approach to examine whether specific farm and family characteristics are related to the likelihood of succession within a given period. We go beyond the existing literature by applying a competing risk approach to study the process and thus the timing, respectively of the two competing events succession or exit from farming. We find that farm characteristics significantly influence succession considerations to the extent that they affect the value of the farm for the potential successor. |

| This report documents data and other information gathered from a survey of urban households in Beijing, Shanghai, and Guangzhou, China. The survey was conducted as part of a research project aimed at understanding the evolution of dairy markets in Asia and the implications for dairy product trade. The survey data provide insights into the purchasing behavior and attitudes of urban consumers in China with respect to dairy products. The report describes the survey and collection process, summarizes selected data from the survey, and provides anecdotal information about the development of dairy production, processing, and product marketing in China. |

| P>1. Metrics have become a standard way for summarizing environmental monitoring results. Different metrics react differently to natural variations and human-induced stressors. We suggest that combined analysis of time trends in selected biological metrics allows identification of biological processes (e.g. individual growth, mortality or recruitment) that have changed (increased or decreased) persistently. Alternatively, time trends in the abundance of sensitive species could indicate changes in environmental stressors. 2. We calculate the joint likelihood of time trends in three metrics and use it to evaluate the evidence in the data for different combinations of metric time trends. A simulation study provides guidelines for interpreting... |

| The knowledge of the overall willingness-to-pay and the specific price premiums consumers accept when buying foods with less fat, saturated fat, sodium, sugar and more fiber shapes food manufacturer and distributor marketing strategies and supports the development of public health strategies. This study applies survey data collected in Korea to identify consumer profiles associated with the expressed willingness to pay a premium for foods with nutritionally desired attributes and, next, estimates the influence of consumer and household characteristics on the WTP a particular premium level for such foods. Results indicate the importance of socio-economic variables such as location, income and education, variables representing the risk of health problems... |

| The aim of this paper is to present an analysis of farm-level data collected in a survey of 464 Polish farms in 2000. Performance indicators of farms in three Polish voivodships are compared with farm accountancy data from two German Länder. The results show that Polish farms are much less profitable than their German counterparts. The gap in income levels is much higher between persons employed in the agricultural sector than between average working persons in the two countries. Living standards of the Polish farm population in the north-west exceed those in the south-east of the country. The analysis suggests that the lower profitability of farms has two major reasons. First, farms in the German regions receive much higher levels of subsidies. Second,... |

| The paper examines profitability and market performance of small-scale fish traders selected randomly from a cross-section of nine fish markets in four districts in Central Uganda. Data were collected through a structured questionnaire which was designed to solicit information on traders’ socio-economic characteristics, marketing characteristics, operating costs and returns, and problems associated with fish marketing in the study area. Percentages were used to describe the socio-economic characteristics, market characteristic and problems associated with fish marketing while gross profit and marketing performance models were used to determine profitability, marketing margin and operational efficiency, respectively. The results suggest that fish trade is... |

| The objective of this study is to analyse at fine scale the annual, seasonal and spatial distributions of several species in the Eastern English Channel (EEC). On the one hand, data obtained from scientific surveys are not available all year through, but are considered to provide consistent yearly and spatially resolved abundance indices. On the other hand, on-board commercial data do cover the whole year, but generally provide a biased perception of stock abundance. The combination of scientific and commercial catches per unit of effort (CPUEs), standardized using a delta-generalized linear model, allowed to infer spatial and monthly dynamics of fish distributions in the EEC, which could be compared with previous knowledge on their life cycles.... |

| This study examines family farms and characteristics affecting farm succession. Based on a farm survey, three aspects of succession are analysed in the paper: the probability of family succession; the likelihood of having a successor designated; and the timing of succession. Large and specialised farms are more likely to be transferred within the family and to have appointed a successor. The number of family members, as well as the experience of farm operator, is also significantly related to the succession behaviour. The probabilities of succession, and of having a successor, first increase with age and then decline again. Furthermore, timing of succession is delayed as the farm holder ages, suggesting most farm operators' succession plans to be... |

| Deep-water sharks exhibit species-specific reproductive strategies, which include segregation by sex, size and reproductive stage. However, due to the wide spatial distribution of most species, available information, usually collected at a regional scale, is usually not adequate to infer species reproductive spatial dynamics. This study draws together information on the distribution of reproductive stages of three species of squaliform sharks: Portuguese dogfish Centroscymnus coelolepis (Somniosidae), leafscale gulper shark Centrophorus squamosus (Centrophoridae) and birdbeak dogfish Deania calcea (Centrophoridae), gathering data from several geographical areas from the Atlantic, Indian and Pacific Oceans. For each species we analysed the sex ratio and the... |

| Multi-year nationwide survey data is used to estimate maize yield response functions and determine profitability of fertilizer use by small-scale farmers in Zambia. There has been a dearth of empirical studies on economics of fertilization in the context of Sub-Saharan Africa. In this paper we identify major methodological issues arising from using survey data and estimate maize yield response functions for small-scale rural households that have various management practices and soil conditions in two major agro-climatic zones. Profitability of fertilizer use is determined for each group of households. Our findings provide the following key messages. First, households that obtained fertilizer on time and used animal draught power or mechanical power for... |

The analysis suggests that the lower profitability of farms is a consequence of pronounced structural deficiencies due to a quite unfavourable workforce-land ratio on Polish farms and... |

| The replacement of wage-labour farms by family farms in Central and Eastern Europe during the transformation has been more limited than was initially expected. In this paper a formal framework is developed in order to analyse the behaviour of family farms and socialist-style farms in the presence of risk, given the typical post-socialist environment. Management incentives, ownership structure, lump-sum transfers and consumption choices are shown to have the potential to limit the size of family farms relative to socialist-style farms. The hypotheses are tested with survey data collected by the author in the Czech Republic. |

| In this paper we use 2001-2002 urban survey data we collected to analyze demographics, cultural factors, and purchasing behaviors influencing the consumption of fresh milk, yogurt, ice cream, and powered milk in urban areas of China. The data include frequency of consumption by product, location of consumption and purchase, exposure to advertising and foreign culture, and school milk programs. The variables serve as regressors in a double-hurdle model that examines the decision to consume or not to consume and the level of consumption. We also estimate consumption levels and participation equations with tobit and probit models. |
