Summary Postwar economic development in Europe can be subdivided in two periods. In the first subperiod 1950–1973 growth is determined by catching up vis-d-vis the US. The second subperiod 1973–1993 is characterised by a reorientation with respect to the international division of labour. This sets the stage for future developments, which are presented in the form of three different scenarios. In the European Decline scenario Europe cannot match developments in the US and Japan. As appears from a scenario called Fortress Europe import protection provides no sensible solution. To compete on a world scale Europe needs more technological dynamics as sketched in the European Recovery scenario. Calculations of future paths are based on the WorldScan model of the Central Planning Bureau.Theo van de Klundert is Professor of Economics at Tilburg University. Ben Geurts and Hans Timmer are staff members of the Central Planning Bureau, The Hague. We are indebted to Martin Fase and Simon Kuipers for useful comments on an earlier version of the paper.  相似文献

Summary In this paper the intertemporal optimization approach is adopted in order to estimate an empirical version of Blanchard's (1985) overlapping generations model. The observed sluggishness in consumption is incorporated into the model by recognizing both durability and habit formation as relevant determinants of total consumption. The model is estimated using quarterly data for The Netherlands from 1969:I to 1990:IV. The empirical estimates suggest that the status of the Dutch consumer as a true Ricardian is unambiguously rejected. The results furthermore suggest that this rejection is due to the existence of both liquidity constraints and finite planning horizons.Comments by Peter Broer, Jeroen Kremers, Debora Molenaar, Rick van der Ploeg, Frans Spinnewyn, Casper de Vries, Ed Westerhout and two anonymous referees are very much appreciated. Elbert Dijkgraaf has provided invaluable research assistance. We also thank participants of the OCFEB workshop and the CES seminar at the K.U. Leuven for their comments.  相似文献

This paper considers the implementation of a nonstationary, heterogeneous Markov model for the analysis of a binary dependent variable in a time series of independent cross sections. The model, previously considered by M offitt (1993), offers the opportunity to estimate entry and exit transition probabilities and to examine the effects of time-constant and time-varying covariates on the hazards. We show how ML estimates of the parameters can be obtained by Fisher's method-of-scoring and how to estimate both fixed and time-varying covariate effects. The model is exemplified with an analysis of the labor force participation decision of Dutch women using data from the Socio-economic Panel (SEP) study conducted in the Netherlands between 1986 and 1995. We treat the panel data as independent cross sections and compare the employment status sequences predicted by the model with the observed sequences in the panel. Some open problems concerning the application of the model are also discussed.  相似文献

We provide an axiomatization of expected equally-distributed equivalent-utility social welfare functions in the context of Harsanyi?s impartial observer theorem. For this family of social welfare functions, we show what additional axiom is necessary and sufficient for the observer to exhibit aversion to ex post inequality. We also relate this axiomatization to our axiomatization in a companion paper of generalized utilitarian social welfare functions. Given certain richness assumptions, the only social welfare functions that belong to both families are the utilitarian.  相似文献

Recent studies of purchasing power parity (PPP) use panel tests that fail to take into account heterogeneity in the speed of mean reversion across real exchange rates. In contrast to several other severe restrictions of panel models and tests of PPP, the assumption of homogeneous mean reversion is still widely used and its consequences are virtually unexplored. This paper analyzes the properties of homogeneous and heterogeneous panel unit root testing methodologies. Using Monte Carlo simulation, we uncover important adverse properties of the panel approach that relies on homogeneous estimation and testing. More specifically, power functions are low and assume irregular shapes. Furthermore, homogeneous estimates of the mean reversion parameters exhibit potentially large biases. These properties can lead to misleading inferences on the validity of PPP. Our findings highlight the importance of allowing for heterogeneous estimation when testing for a unit root in panels of real exchange rates.  相似文献

Offshore outsourcing of business functions is widely practiced by firms in advanced economies. Although scholars have argued for various theoretical perspectives in explaining its nature and implications, a coherent explanation of how crucial factors that aid this growing phenomenon coevolve has not been offered. Further, a potential gap in the extant literature concerns inadequate simultaneous attention to clients and providers – the key actors in offshore outsourcing. With an aim to fulfill these research gaps, we provide in this paper an integrated framework wherein we delineate various institutional and organizational factors that coevolve to enable engagement of clients and providers in offshore outsourcing. Our conceptualization draws from information obtained by interviewing 46 executives of 31 firms of the Indian business process outsourcing industry.  相似文献
