Based on the AMSZ (1989) criterion, we exploit comprehensive datasets to estimate the dynamic efficiency of world economy. The results reveal that the representative econo-mies conform to a "U-shaped pattern" in their evolution of capital accumulation. That is, a period of decreasing efficiency (over-accumulation) followed by increasing efficiency (de-accumulation). Contrary to previous evidence, the bias-corrected estimates show that major economies have been inconsistently dynamically efficient. As a prime example, China today is unquestionably in a state of severe dynamic inefficiency, and the inefficient status is likely to continue in near future. We also document the limitations of the AMSZ criterion and point out promising research directions in the efficiency literature.

We propose a new quantitative recession magnitude scale for measuring recessions' magnitudes ('strength') derived from GDP growth rates during a recession and its duration. Furthermore, we introduce a qualitative scale with four recession categories: minor, major, severe and ultra, where the categories are defined by the magnitude scale. We use both scales to evaluate several well known economic recessions of the 20th and the 21st centuries. We have found that the Great Depression in 1929-1933 and recessions in Russia and Ukraine in the 1990s belong to ultra recessions, while the recent 2007-2009 financial crisis falls mainly into major (EU and Japan) and severe (USA) category.

This paper suggests that real GDP is not an appropriate indicator for long-term comparisons of the performance of transformation and post-transformation economies either with developed economies, or one with another, or across different phases of development of a single economy. We analyse the possible reasons why real GDP diverges from the theoretical concept of the objective level of value added adjusted for inflation. These reasons concern real exchange rate appreciation and overestimation of inflation due to quality changes in output after the collapse of central planning. To overcome the shortcomings of real GDP in explaining the true "transformation story" we develop the concept of "comparable" real GDP. This concept is calculated from nominal GDP, the exchange rate against the euro, and inflation in the euro area. While the differences between "standard" real GDP and "comparable" real GDP are modest and temporary in advanced economies, they are quantitatively and qualitatively significant and persistent in transformation and post-transformation economies. On the basis of the relevant literature we introduce two modifications of "comparable" real GDP. They account for likely differences in productivity patterns between tradables and non-tradables and between the performance of the export and non-export segments of the economy respectively. We conclude that true convergence is proceeding at a significantly higher pace than real GDP implies and that the Czech economy is converging to the euro area somewhat faster than the Polish economy and much faster than the Hungarian economy.

The aim of the article is to propose a new measure of a relative economic distance between two countries (RED) or among a group of countries (GRED). Both measures enable to evaluate 'proximity' between national economies through time series of selected variables, and are related to the concept of the sigma (beta) convergence introduced by Barro and Sala-i Martin (1995). In the empirical part of the paper, the RED of Poland, Slovakia, Austria, Germany, the USA and Japan with regard to the Czech Republic are estimated, as well as the time evolution of the GRED of the Czech Republic and its neighbours. The main finding is the strong convergence among these countries after the outbreak of the financial crisis which persists to this day.

The new EU-entrants face double challenge on the Lisbon road to knowledge-based competitiveness. On the one hand, higher expenditure is required to improve the quality of research and education input and infrastructure, on the other hand, the innovation system changes are necessary to increase efficiency of expenditures. The example of the Czech Republic within EU-25, as to the export performance, productivity and R&D intensity of the so-called hi-tech activities, presents a more detailed analysis of competitive advantage sources and challenges in the less developed EU members. The analysis emphasizes the criterion of (in)completeness of the multinational value chain, which continues to consist mainly of segments with lower quality intensity (assembly operations) in these countries. This aspect plays a crucial role in international comparison of competitiveness within EU-25, and in assessment of success and political support of transition to knowledge-based economy.

The article analyses the economic development of transition economies (the CR, Hungary, Poland, Slovakia and Slovenia) in the nineties by means of the original graphical method based on a multidimensional view, with the intention to assess convergence or divergence of their economic level vis-a-vis the average level of the EU countries. The polydimensional aspect is based in the first step on four basic objectives of economic policy depicted by the macroeconomic (magic) tetragon. In the second step, an each quadrant of the magic tetragon is extended by six detailed indicators to get a multidimensional convergence polygon. The polygon framework allowed carrying out more detailed analysis of the convergence process. The detailed results of the multidimensional convergence analysis varied across individual countries and over time; the time path of these differences partly reflected the uneven progress in macroeconomic stabilization and recovery of economic growth.
