Panel Design

Surveys with a rotating panel design are a prominent tool for producing more efficient estimates for indicators regarding trends or net changes over time. Variance estimation for net changes becomes however more complicated due to a possibly high correlation between the panel waves. Therefore, these estimates are quite burdensome to produce with traditional means. With the R-package surveysd, we present a tool which supports a straightforward way for producing estimates and corresponding standard errors for complex surveys with a rotating panel design. The package uses bootstrap techniques which incorporate the panel design and thus makes it easy to estimate standard errors. In addition the package supports a method for producing more efficient estimates by cumulating multiple consecutive sample waves. This method can lead to a significant decrease in variance assuming that structural patterns for the indicator in question remain fairly robust over time. The usability of the package and variance improvement, using this bootstrap methodology, is demonstrated on data from the user database (UDB) for the EU Statistics on Income and Living Conditions of selected countries with various sampling designs.

The Weiss affair, culminating in the BVerfG ruling of 5 May 2020 ( Weiss II), marks a break-up point in the long-standing dialogue between the BVerfG and the CJEU. The judges in Karlsruhe refused to follow the decision rendered by the CJEU in a preliminary ruling ( Weiss I) and ordered EU institutions to provide further clarifications on the proportionality assessment of the Public Sector Purchase Programme. This paper claims that the principles applied by the BVerfG in Weiss I are quite similar to those employed in the Gauweiler and Landeskreditbank-Banking Union cases. Considering that background, it will be argued that the construction of the principles employed by the BVerfG for the judicial review of EU acts did not undergo dramatic changes over time. The different outcome of Weiss II is due to the fact that, according to the BVerfG, insufficient elements of explanation and justification were provided by the ECB and the CJEU. Therefore, the central problem of Weiss II ends up being a procedural question of allegedly insufficient statements of reasons. From Gauweiler to Weiss II, one also sees the development of the standards for the judicial review of the ECB’s decisions, in the fields of both monetary policy and banking supervision.

Over Time

The aim of this article is to shed some light on the behaviour of income inequality and inequality of opportunity over time for 26 European countries. The analysis is carried out using microdata collected by the European Union Statistics on Income and Living Conditions (EU-SILC), which incorporate a wide variety of personal harmonised variables, allowing comparability between countries. The availability of this database for the years 2004 and 2010 is particularly relevant to assess changes over time in the main inequality indices and the contribution of “circumstance” to inequality of opportunity. Bootstrap methodology is used with the aim of testing if the differences between the two years are statistically significant. Results show that observed changes in inequality of opportunity and income inequality are in most cases significant and also prove the robustness of the bootstrap methods to analyse the evolution of income inequality and inequality of opportunity.

The article attempts to identify the most important changes in the international trade of pork and pigs after the announcement of the embargo by the Russia. For the verification of the main goal of article were used the analysis of changes over time and an analysis of the structure of the total foreign trade (exports and imports) and with Russia in 2011-2015. The used data come from the Ministry of Finance. The situation on the domestic pork market in 2014 was difficult due to the significant increase in pork production both in Poland and in the EU, the occurrence of the ASF (and related restrictions on exports to many third countries), and introduction the embargo by Russia, which was one of major buyers of pork products exported from Poland. As a result, the geographic structure of exports had changed. In the analyzed period Poland was a net importer of pork products and the foreign trade balance of these products with Russia was positive.

Abstract. Summary: Background: We aimed at estimating the agreement between the Medicap® (photo-optical) and Radiometer® (electro-chemical) sensors during exercise transcutaneous oxygen pressure (tcpO2) tests. Our hypothesis was that although absolute starting values (tcpO2rest: mean over 2 minutes) might be different, tcpO2-changes over time and the minimal value of the decrease from rest of oxygen pressure (DROPmin) results at exercise shall be concordant between the two systems. Patients and methods: Forty seven patients with arterial claudication (65 + / - 7 years) performed a treadmill test with 5 probes each of the electro-chemical and photo-optical devices simultaneously, one of each system on the chest, on each buttock and on each calf. Results: Seventeen Medicap® probes disconnected during the tests. tcpO2rest and DROPmin values were higher with Medicap® than with Radiometer®, by 13.7 + / - 17.1 mm Hg and 3.4 + / - 11.7 mm Hg, respectively. Despite the differences in absolute starting values, changes over time were similar between the two systems. The concordance between the two systems was approximately 70 % for classification of test results from DROPmin. Conclusions: Photo-optical sensors are promising alternatives to electro-chemical sensors for exercise oximetry, provided that miniaturisation and weight reduction of the new sensors are possible.
