Among many other problems, the migration, humanitarian and policy crises in the European Union in 2015 and early 2016 have highlighted a pressing need for reliable, timely and comparable statistical data on migration, asylum and arrivals at national borders. In this fast-moving policy field, data production and the timeliness of dissemination have seen some improvements but the sources of data remain largely unchanged at national level. In this paper the author examines the reasons for some of the problems with the data for policy and for public discussion, and makes a set of recommendations that call for a complete and updated inventory of data sources and for an evaluation of the quality of data used for policy-making.

The Party of Regions took power in early 2010, after Ukraine had been plunged deep in economic crisis. Over the next year, with the external markets recovering, the country’s economic situation started to improve gradually. Ukraine’s economic stabilisation was also strengthened by its resumed cooperation with the International Monetary Fund, which provided for a loan worth $15.1 billion. The issuing of successive tranches of the loan was made dependent on the implementation of a comprehensive reform programme. The cooperation went quite smoothly at first; however, as the economic situation in Ukraine improved, the reformist zeal of the Ukrainian government started to fade, and obstacles began piling up. As a result, Ukraine was refused the third tranche, scheduled for this March, and for the moment the credit line remains frozen. Even though the IMF has numerous reservations about the Ukrainian government’s economic policy, the fundamental condition for resuming cooperation is reform of the pension system, which the parliament should adopt. The difficulties with fulfilling the obligations made to the IMF reflect the wider problem with implementing reforms in Ukraine, as the Party of Regions promised after taking power. Changes which do not affect the interests of influential lobbies are quite easy to carry out. Often, however, these changes are not conducive to the economy’s liberalisation; moreover, the influential lobbies are successful in blocking reforms that could harm their businesses. Another impediment to the changes is that some reforms are likely to bring about painful social consequences, and that can affect public support for the ruling group. Even though theoretically possible, it does not seem likely that Ukraine’s cooperation with the IMF will be terminated. But even if this cooperation is continued, deeper reforms in Ukraine are likely to be postponed until after the parliamentary elections in autumn 2012.

The inventors in PATSTAT are often duplicates: the same person or company may be split into multiple entries in PATSTAT, each associated to different patents. In this paper, we address this problem with an algorithm that efficiently de-duplicates the data. It needs minimal manual input and works well even on consumer-grade computers. Comparisons between entries are not limited to their names, and thus this algorithm is an improvement over earlier ones that required extensive manual work or overly cautious clean-up of the names.

Over the past few months, four Central European states have made decisions which will determine the shape of their air forces over the next decade. On 11 October, Romania signed a contract under which it will buy twelve used US F-16A/B multi-role fighter aircraft from Portugal. In August, Slovakia signed contracts with Russia’s MiG for repairs and the limited modernisation of its twelve MiG-29 fighter aircraft currently in service. The Czech Republic entered into a preliminary agreement in July with Sweden on extending the lease of fourteen JAS-39 Gripen multi-role fighter aircraft (the new Czech government will hammer out the details following the parliamentary election). Bulgaria, which has been facing financial problems and political instability, in June postponed the purchase of new (non-Soviet) combat aircraft at least until the end of this year. If Sofia decides to buy any within the next few years, these will be not more than twelve relatively old and worn-out machines (most likely F-16A/B from Portuguese or Dutch army surplus). Given the fact that Hungary in 2012 made the same decision regarding its fourteen Gripen aircraft as the Czech Republic, there are good grounds to claim that the capabilities Central European NATO member states have to take action in airspace are durably limited. The region’s saturation with combat aircraft is the lowest when compared to the entire continent (with the exception of the Baltic states). Furthermore, the machines to be used in the coming decade will be the oldest and the least advanced technologically (all of them belong to the so-called “fourth generation”, the roots of which date back to the 1970s). The problem with gaining full interoperability within NATO has not been resolved in its Central European member states. By modernising its MiG-29 aircraft, Slovakia is to say the least postponing the achievement of interoperability once again. Bulgaria will gain interoperability by buying any Western combat aircraft. However, it is very unlikely to introduce new machines into service earlier than at the end of the present decade. Since the introduction of new fifth generation multi-role combat aircraft or transitional 4+ generation machines in the region’s air forces is unrealistic, the defence of the airspace of NATO member states in Central Europe can be termed an ever more porous sky.
