    Industry - and firm-level research into both innovations and productivity has long been limited to manufacturing. With this paper, we aim to contribute to the stream of literature that aims at extending the scope of such investigations to the services industry. To this end we analyze the innovation strategies in several service sectors in Poland in 2008 and examine their relationship to productivity. Our results show that service firms differ considerably in their innovation strategies, but that most of those strategies lead to productivity gains

    What are service sector innovations and how do we measure them?

    Services dominate all advanced economies but service innovations are still an underresearched topic. One of the reasons are definitional and measurement difficulties. The goal of the paper is to highlight those by reviewing recent literature and to assess the current state of knowledge and challenges. Theoretical approaches, empirical techniques and selected empirical results are discussed. Apparently the biggest challenge, at this point, is to create a unified conceptual framework, that would encompass both manufacturing ad services. Meeting this challenge will, however, be difficult, given the strong focus on manufacturing, both in the literature and in the way enterprise surveys are designed.innovation, services, manufacturing

    Growth and Performance Factors in Polish Manufacturing Firms in 1998-2003 in the Light of Survey Data

    We investigate possible factors of change in employment between 1998 and 2003 in 220 companies from four industries of Polish manufacturing (food, electronics, automotive and pharmaceuticals), that were subject to an enterprise survey. We also seek to explain the differences in performance among companies. We find that firms that were more competitive and more innovative laid off relatively less workers. Ownership status and history seem to be relevant factors too, as companies that were started as private businesses slightly increased employment, while the state-owned enterprises experienced proportionally the largest employment cuts; as for privatized companies, those taken over earlier performed better in terms of employment than those privatized later. However, econometric analysis of premia of early privatization and foreign ownership showed that only the latter factor played a significantly positive role for companies' revenues, productivity, profitability and the level of wages.employment, privatization, FDI, competitiveness, manufacturing

    Identifying Vertical Product Differentiation in Three Polish Manufacturing Industries: an Enterprise Survey

    Get PDF
    The paper attempts to identify indirectly vertical product differentiation in three industries of Polish manufacturing (manufacture of glass and glass products, manufacture of other general purpose machinery and manufacture of other special purpose machinery) by examining how focus on a given group of customers (segment) is related to company characteristics. Changes in companies' segment orientation between 2002 and 2005 are examined and the factors of these changes are discussed. The analysis is based on a survey of 77 companies. The data support the hypothesis that there exist segments in the consumer goods market, defined by the income level of customers. In the capital goods market, it is shown that domestic-owned customers are the low-end segment of the market, whereas foreign-owned customers constitute a higher segment. It seems that industries producing capital goods have shifted towards higher market segments between 2002 and 2005 and their principal motive was the pressure exerted by competitors, both domestic and foreign.product differentiation, quality, competitiveness, manufacturing.

    D-divisible quantum evolution families

    Get PDF
    We propose and explore a notion of decomposably divisible (D-divisible) differentiable quantum evolution families on matrix algebras. This is achieved by replacing the complete positivity requirement, imposed on the propagator, by more general condition of decomposability. It is shown that such D-divisible dynamical maps satisfy a generalized version of Master equation and are totally characterized by their time-local generators. Necessary and sufficient conditions for D-divisibility are found. Additionally, decomposable trace preserving semigroups are examined
