In 2004, 75 million people are scheduled to become EU citizens, making this the largest round of expansion of the Western European club to date. Of the 10 new entrants, 8 are former socialist economies, for which membership in the EU represents the coronation of an effort began with the fall of the Berlin wall in 1989. Based on their recent economic performance, the Central and Eastern European countries appear to be well on their way to successfully integrate in the Western European club, while the Baltic Republics still lag behind. The gap between the two groups emerges when we consider the adjustment of the production structure, the composition of trade and FDI flows, and income distribution. The evidence we review appears to support the role of institutional quality to facilitate integration in the world market and overall economic performance.  相似文献

Over the last two decades privatization programmes in a variety of different countries have radically reduced the role of the state as a major owner of productive assets. While there is empirical evidence to show that the switch in ownership generally improves productive efficiency and profitability at company level, its effects on research and development (R&D) activities, which can impact strongly on long–term performance, have been largely ignored in the literature.
In this paper we address this issue by analyzing seven cases of privatization that have recently occurred in Italy and France in order to gauge how R&D activities may be affected by privatization in terms of objectives and organization. The organizations studied show that R&D units within privatized companies are subject to profound restructuring actions, generally designed to boost efficiency and to strengthen integration with the goals of the business units and of the final customers. A new role for R&D thus emerges: the aim is no longer to generate new knowledge in the broad national interest, but rather more directly to create value for the company and its clients, by emphasizing the assessment and integration of external knowledge.  相似文献

Drawing on the theory of organisational routines as generative systems, we deploy a critical realist approach based on Searle's philosophy of language to analyse the generative mechanisms that specify the pre-conditions for recognisable, repetitive patterns of interdependent activities. Using the example of the organisational routines implemented in Germany to monitor the allocation and disbursement of the European Social Fund, we contend that constitutive rules of the type “X counts as Y in context C” are at the very centre of organisational routines. Such rules consist of generative mechanisms that account for the emergence of the ostensive aspects of organisational routines out of artefacts and/or procedures in a social structure of power relations. We further claim that, far from being proxies for the ostensive aspects of routines, artefacts whether tangible or intangible are instantiations of such ostensive aspects on a par with any other performative aspects of routines. On this basis, a re-conceptualisation and a re-labelling of the ostensive and performative aspects of routines are proposed. The former are the result of the activation of systems of constitutive rules, i.e. actual routines in critical realist terminology, the latter are patterns of interdependent activities instantiating the ostensive aspects of routines, i.e. empirical routines in critical realist terminology. Implications for theory and practice are discussed by developing a model of organisational routines that interweaves extant research streams.  相似文献

This paper reports experiments with one-stage and two-stage alternating-offers bargaining games. Payoff-interdependent preferences have been suggested as an explanation for experimental results that are commonly inconsistent with players' maximizing their monetary payoffs and performing backward induction calculations. We examine whether, given payoff-interdependent preferences, players respect backward induction. To do this, we break backward induction into its components, subgame consistency and truncation consistency. We examine each by comparing the outcomes of two-stage bargaining games with one-stage games with varying rejection payoffs. We find and characterize systematic violations of both subgame and truncation consistency. Journal of Economic Literature Classification Numbers: C70, C78.  相似文献

The classical stochastic frontier panel data models provide no mechanism to disentangle individual time invariant unobserved heterogeneity from inefficiency. Greene (2005a, b) proposed the so-called “true” fixed-effects specification that distinguishes these two latent components. However, due to the incidental parameters problem, his maximum likelihood estimator may lead to biased variance estimates. We propose two alternative estimators that achieve consistency for n with fixed T. Furthermore, we extend the Chen et al. (2014) results providing a feasible estimator when the inefficiency is heteroskedastic and follows a first-order autoregressive process. We investigate the behavior of the proposed estimators through Monte Carlo simulations showing good finite sample properties, especially in small samples. An application to hospitals’ technical efficiency illustrates the usefulness of the new approach.  相似文献

We analyze the role of leadership in a multi-sided market as search advertising, assuming quantity competition and different entry conditions (with barriers to entry or endogenous entry). The model can be microfounded taking into account network effects, multi-homing on the advertising side and scale in search. If there are barriers to entry and the network effects are strong, there is an incentive for the leader to exploit them and attract more consumers to monopolize advertising. Under barriers to entry, the leading platform has also a strategic incentive to exploit scale in search, to manipulate search results to divert search traffic from other platforms, and to introduce limits to multi-homing, with the aim of expanding its market share and deny scale to competitors.  相似文献

This paper studies the institutional design of the coordination of macroeconomic stabilization policies within a monetary union in the framework of linear quadratic differential games. A central role in the analysis plays the partitioned game approach of the endogenous coalition formation literature. The specific policy recommendations in the European Economic and Monetary Union (EMU) context depend on the particular characteristics of the shocks and the economic structure. In the case of a common shock, fiscal coordination or full policy coordination is desirable. When anti‐symmetric shocks are considered, fiscal coordination improves the performance but full policy coordination does not produce further gains in policymakers' welfare.  相似文献
