    Participation in household surveys has fallen over time, making it harder to produce a household survey-like the Survey of Consumer Finances (SCF)-in a timely manner. To address these challenges, the reference year of the sampling frame data for the 2016 SCF wealthy oversample was shifted back one year, allowing the oversample to be selected earlier than the past. In implementing this change, though, we risk identifying an outdated set of families and introducing variability in the sampling process. However, we show that the set of families selected in the new frame are observationally equivalent to those that would have been selected from a past frame, and that the increased variability of wealth estimates is compensated-for with the use of more comprehensive data than in the past. Other aspects of the SCF sampling process are revisited, too. We continue to find support for using permanent income in the sampling process, rather than annual income. We also estimate the geographic distribution of wealthy families and show that the current distribution is similar to the past. We propose adding one geographic area to the oversample, though, and supplementing by 100 the set of sampled families

    Die Produktivität von Waldökosystemen wird durch die Bereitstellung von Nährstoffen und Wasser gewährleistet. Somit ist das Wissen über die chemischen und physikalischen Eigenschaften der Böden essentiell sowohl zur Beurteilung des Bodenzustands als auch der Güte des Waldstandorts. Hierfür können Daten aus zwei bundesweiten Bodenzustandserhebung im Wald (BZE-Wald) von über 1.800 Probepunkten eines 8 x 8 km-Grundrasters herangezogen werden. Die Erhebungen fanden zwischen 1986 bis 1994 (BZE I-Wald) und 2006 bis 2008 (BZE II-Wald) nach einheitlichem Aufnahmeverfahren statt. Das LUCAS-Projekts zielt auf die Erstellung eines harmonisierten Datensatz zur Landbedeckung und Landnutzung innerhalb der Europäischen Union (EU). Das Europäische Datenzentrum (ESDAC) stellt 265.000 georeferenzierte Punkte auf einem 2 x 2 km-Raster bereit, die jeweils in den Jahren 2009 und 2015 an 10 % der Punkte am gleichen Standort beprobt wurden. Angesichts von zwei parallellaufender Bodeninventuren stellt sich die Frage einer potentiellen Verknüpfung miteinander. In dieser Studie werden die LUCAS-Bodendaten der Inventur des Jahres 2015 mit den entsprechenden bundesweiten BZE-Daten verglichen und auf ihre Repräsentativität überprüft. Um eine flächengewichtete Hochrechnung für Deutschland zu ermöglichen, erfolgte eine Zordnung der Inventurpunkte des LUCAS-Programms anhand ihrer Koordinaten zu den bei der bundesweiten BZE-Auswertung verwendeten 16 BZE-Substratklassen. Alle Klassen wurden hinsichtlich signifikanter und systematischer Unterschiede zwischen beiden Inventuren überprüft. Darüber hinaus wurden die BZE-Daten dahingehend evaluiert, inwieweit die ausschließlich im LUCAS Programm verwendete Tiefenstufe 0-20 cm im Vergleich zum Mineralboden bis in 90 cm Tiefe und der Humusauflage bei der Berechnung von Vorräten zukommt. Der Vergleich der bodenchemischen Kennwerte ergab deutliche Unterschiede zwischen den Inventuren. Sowohl die pH(H2O)-Werte als auch die C/N-Verhältnisse waren bei LUCAS 2015 niedriger, die Konzentrationen von C und N jedoch höher als bei der BZE II. Die Vorräte an Kohlenstoff und Sticksoff weisen noch größere Abweichungen gegenüber der BZE II aufgrund der Unsicherheiten bei der Ableitung von Trockenrohdichten aus Kartenmaterial auf. Im Gegensatz dazu erfolgte durch die BZE II eine volumenbezogene Beprobung an fast allen Standorten. Eine Ableitung von Trockenrohdichten aus Kartenmaterial führt bei der LUCAS-Inventur zu einer hohen Unsicherheit der Ergebnisse und zu einer Überschätzung von Vorratsänderungen. Die höheren Kohlenstoff- und Stickstoffkonzentrationen bei der LUCAS-Inventur könnte an einer unzureichend genauen Trennung der organischen Auflage vom Mineralboden liegen, da dieser durch Bestandteile der Auflage aufkonzentriert würde. Während der Erhebung der BZE-Wald wurde explizit auf die systematische Trennung beider Kompartimente geachtet. Weiterhin steht die Anzahl der beprobten LUCAS-Waldpunkte im Missverhältnis zur Waldfläche, da in Nord- und Süddeutschland zu wenig Probepunkte vorkamen. Allerdings sind die Waldanteile der LUCAS-Gesamtinventur mit denen der dritten Bundeswaldinventur vergleichbar. Die Stichprobengröße von LUCAS 2015 umfasst etwa 25 % der BZE II-Stichprobe. Hierdurch sind einige Substrattypen nur unzureichend belegt, weshalb zum einen wesentliche Bodeneigenschaften unberücksichtigt blieben und andererseits eine flächengewichtete Hochrechnung erschwert werden würde. Infolge der geringeren Stichprobe weichen die bodenchemischen Kennwerte der einzelnen Substratgruppen zwischen den Messnetzen ab. Außerdem erhöhen sich die Unsicherheiten durch die Reduzierung der Stichprobe. Somit ließen sich Bodenveränderungen bei einer Wiederholungsinventur schwerer detektieren. Die Daten aus den Bodeninventuren sind für die Treibhausgasberichterstattung relevant, da Kohlenstoffvorräten für die organische Auflage und für den Mineralboden bis zu einer Tiefe von mindestens 30 cm zu berichten sind. Im Mittel werden nach den Daten der BZE II 16 % des bis 90 cm Tiefe vorkommenden Kohlenstoffs in der Auflage gespeichert, wobei diese mit der LUCAS-Inventur nicht beprobt wurde. Der in der organischen Auflage gebundene Kohlenstoff ist vulnerabel gegenüber Klima- und Umwelteinflüssen, so dass eine Auswertung diesbezüglich nicht möglich ist. Weiterhin wurde bei LUCAS 2015 nur die oberen 20 cm des Mineralbodens beprobt und damit lediglich 42 % des bei der BZE II abgeschätzten Kohlenstoffs erfasst. Durch das Fehlen der Auflage und die geringere Tiefe sind die Daten aus LUCAS 2015 nur eingeschränkt für die Treibhausgasberichterstattung nutzbar. Aufgrund einer geringeren Repräsentativität sowie größeren Unsicherheiten und Diskrepanzen von LUCAS 2015 gegenüber der BZE im Wald würde eine Vereinigung beider Datensätze keine zusätzlichen Synergien erzeugen. The productivity of forest ecosystems depends on the supply of both nutrients and water by soils. Therefore, the knowledge of the chemical and physical soil properties is crucial for assessing the soil condition as well as the quality of forest sites. For this purpose, data are available from two nationwide Forest Soil Inventories (NFSI) on more than 1,800 sample plots of an 8 x 8 km grid. The inventories were conducted between 1986 and 1994 (NFSI I) and 2006 and 2009 (NFSI II) in accordance with harmonized surveying techniques. The LUCAS Project aims at the development of a harmonized dataset on land cover and land use within the European Union (EU). Approximately 265.000 georeferenced plots on a 2 x 2 km grid were available from the European Soil Data Centre (ESDAC). Soil samples were taken in 2009 and in 2015 at approximately 10 % of these plots at the same locations. Considering two almost parallel running soil inventories, questions have arisen to their potential links to one another. In this study, the LUCAS soil data from the 2015 inventory were compared with the corresponding NFSI II data and reviewed under the aspect of representativeness. In order to enable an area weighted estimation for Germany the plots of the LUCAS program were attributed to the same 16 soil parent material groups used in the German NFSI data using geographical coordinates. All classes were tested for significant and systematic differences between the inventories. To quantify C stocks, it is important to compare the depth level 0-20 cm of the LUCAS program to Germanies NFSI sampling scheme, where data available for the organic layer and the mineral soil down to 90 cm. The comparison of various chemical soil parameters showed clear differences between the inventories. The pH(H2O) and the C/N ratio derived from LUCAS 2015 was lower while carbon (C) and nitrogen (N) concentrations were higher compared to the NFSI II. The C and N stocks deviate even more from the NFSI II due to uncertainties in the estimation of bulk densities derived from maps. By contrast Germany’s NFSI, were volume-based sampling was obligatory for almost all plots. As a result, fine earth stock estimates from map derived bulk densities could result in highly uncertain and overestimated stocks change rates. Higher C and N concentrations of the LUCAS inventory could be attributed to an insufficient separation of the organic layer from the mineral soil because if the separation is not practiced carefully, residues of the organic layer can contaminate the mineral soil sample and cause significant higher concentrations. The soil sampling of the NFSI focused explicitly of the systematic separation of both compartments. The number of the sampled forest plots of LUCAS 2015 showed a lack of representativeness because in the northern and southern parts of Germany an insufficient number of plots were sampled. Nevertheless, the proportion of the forest area of the total LUCAS inventory is comparable with Germany’s Third National Forest Inventory. The selected LUCAS 2015 samples comprise 25 % of the NFSI II plots which results in an insufficient coverage of various soil groups. This means that soil properties remain unconsidered and that the area-weighted extrapolation could become more difficult. Chemical soil parameter within in individual substrate groups differed between the sampling grids due to the smaller sample of LUCAS 2015 compared to the NFSI II. Moreover, the reduction of sampling plots results in an increase of uncertainties. Thus, the detection of changes in soil conditions could be more difficult in respect to repeated sampling. Soil inventory data are of importance in greenhouse gas reporting because C stocks the organic layer and the mineral soil down to 90 cm must be reported. The analysis of the NFSI II revealed that the organic layer comprises 16 % of the C stored in the entire soil profile. The organic layer was not sampled in the LUCAS inventory. Nevertheless, changes in C stored in the organic layer is vulnerable to impacts of climate and other environmental and anthropogenic variables but the effects cannot be considered with LUCAS 2015. Due to the LUCAS 2015 mineral soil sampling depth down to 20 cm only 42 % of the stored C was detected in the entire soil profile. Therefore, data based on LUCAS 2015 are insufficiently qualified for the greenhouse gas reporting due to the lack of a sampled organic layer and the limitation to the sampling depth of 20 cm. Compared to Germany’s NFSI, the results based on the LUCAS inventory revealed a smaller representativity and were associated with larger uncertainties as well as discrepancies. Consequently, the union of both data sets will not result in additional synergies.

    Sampling poses an interesting problem in markets with experience goods. On the one hand, free samples reveal product quality and help consumers to make informed purchase decisions (promotional effect). On the other hand, sampling may induce consumers to substitute purchases with free consumption (displacement effect). We look at this trade-off in the market for digital music where consumers can sample the horizontal quality of songs by watching free music videos online. Identifi cation comes from a natural experiment in Germany, where virtually all videos that contain music are blocked on a popular video platform due to a legal dispute ith representatives of the rights-holders. We show that promotional and displacement eff ects cancel out in the sales performance of songs, whereas online music videos trigger sales of albums.

    The Survey of Consumer Finances (SCF) has a dual-frame sample design that supplements a standard area-probability frame with a sample of observations drawn from statistical records derived from tax returns. The tax-based frame is stratified on the basis of a "wealth index" constructed largely from observed income flows, with the intent of heavily oversampling wealthy households. Although the SCF is not specifically designed to estimate wealth concentration, the design arguably provides sufficient support to enable such analysis with a reasonable level of credibility. Similar estimates may also be made by using tax-based data directly, by using a construct very close to a key part of the SCF wealth index. Such an approach has appeal as a way of tapping a much larger set of information to improve SCF estimates. Not surprisingly, there are differences in the two approaches, largely as a result of conceptual differences or complications in the survey implementation. This paper focuses on the top 1 percent of the wealth distribution, the group most intensively covered by the SCF list sample and it explores the stability of the relationship between the patterns of concentration in the survey data and parallel patterns in tax-based estimates and considers how those patterns differ across survey participants, the full sample and the entire survey frame. In addition, the paper makes as series of recommendation for further research on the technical support of the survey
