| This paper utilizes the feature of the CHDS data from New Zealand that children are sampled for extremely long individual histories of their class size experiences as well as their scholastic and early labor market outcomes. Our interest is to explore the full set of empirical implications of the recent experimental evidence on class size effects on student achievement from the United States in Project STAR for observational data. We argue that one implication of Project STAR is that only persistent class size reduction policies may have detectable effects, and so the longitudinal aspect of CHDS is necessary to detect class size effects. We account for the observational nature of the CHDS (in that children were not randomly assigned to different class... |

| The roots and uses of economic experiments in problem solving and hypothesis testing are explored in the present article. The literature suggests that the primary advantage of economics experiments is the ability to use controlled stimuli to test economic hypotheses. Other literature also suggests that experiments are useful in problem solving settings. The advantages and disadvantages of experiments are discussed. |

| The authors, inside a TAPAS action, have developed a methodology - based on the integration between FADN data with statistical, administrative and cartographic information - to improve the production of statistical data related to agricultural policies impact on land and environment. This methodology allows - using Geographic Information System (GIS) technology - to produce and organise data at geographical level. Data spatially referenced respond to the specific needs of agri-environmental analysis and problems, mostly related to specific areas (environmental vulnerability areas), inside defined boundaries (e.g. river basin). The GIS is implemented with several cartographic layers (Topographic and cadastral maps, land use, soils, water sources, climate,... |
