Convergence among nations that share the same preferences and technologies is a key result of the closed‐economy neoclassical growth framework that has received substantial support in the data. However, Heckscher–Ohlin versions of the two‐sector neoclassical growth model predict that nations that differ in their capital–labor ratios may not converge to the same steady state, even if they are identical in all other aspects. This is a puzzling result that warns us about potential dangers of international trade. In this paper we show that when land, an input in fixed supply, is introduced into the model, international trade in goods no longer limits the capacity of poor nations to catch up with the advanced world.  相似文献

Many firms attempt to develop market‐oriented attitudes and behaviors because of their presumably positive consequences for performance. A market orientation can provide the cultural basis for successful differentiation strategies focused on customer satisfaction. However, inconclusive evidence regarding the relationship between market orientation and performance demands an analysis of possible moderators. This paper therefore analyzes the moderating role of environmental characteristics in the market orientation–performance relationship. Heterogeneous methodologies and measures could explain some diversity in empirical results. Moreover, both the market orientation–performance relationship and the moderating effects of environment dynamism, turbulence, hostility, and complexity may depend on more general characteristics of the environment. A complete diagnostic of the moderating effect of the environment must analyze phenomena in different socioeconomic and political–regulatory contexts. Therefore, the authors (1) analyze the moderating role of environmental dynamism and competitive intensity; (2) consider a broad range of performance measures, distinguished as effectiveness, efficiency, and adaptability measures and as financial and operational measures; and (3) focus on a priority 1 region of the European Union, characterized by small and medium‐sized enterprises that face a global competitive scenario from a disadvantaged local environment. The empirical results support the positive relationship between market orientation and performance and indicate the relationship is inhibited by competitive intensity, which contrasts with existing arguments and empirical results.  相似文献

This article sets out to highlight the importance of adopting customer orientation and information and communications technology (ICT) in tourism service delivery if the rural tourism sector is to succeed. A model is proposed and validated which encompasses the effects of customer orientation adoption and the use of ICT on the rural tourism sector, taking into account the enterprises’ financial results, improvements to the rural destination, and the more personal, intangible impact on the owner-manager. The major contributions of this work are in finding that customer orientation adoption that contributes to ICT use, and that both ICT use and customer orientation adoption contribute to better outcomes from rural tourism activity.  相似文献

The aims of the present work centre on determining whether co-created value constitutes a competitive advantage for firms, and whether it is capable of influencing consumer behaviour. Applying the service-dominant logic perspective, the work examines the firm's capabilities in the context of its business-to-customer (B2C) interactions, focusing on information and communications technology (ICT) as a particular driver of value co-creation. Taking this B2C perspective, ICT is measured, from the firm's point of view, and customer perceptions are analysed, using the variables ‘value co-creation’, ‘perceived value’ and ‘loyalty’. The sample consists of 100 service firms and 572 of their customers. The findings indicate that ICT capabilities have a direct effect on value co-creation, as does value co-creation on perceived value and loyalty.  相似文献

This paper analyses the relationship between the Spanish peseta, the currency of a peripheral country, and the pound sterling, the central currency of the gold standard. From 1883, when Spain suspended metallic convertibility, until 1931, when Great Britain definitively abandoned gold, the peseta was a fiat currency with a flexible exchange rate regime. Our results confirm, first, long-run PPP hypothesis compliance for the peseta/pound sterling rate during the period. Secondly, we illustrate how the inclusion of peripheral variables (erratic trade and financial risk), significantly improves the short-run adjustment to the PPP hypothesis. It appears that the floating regime thus helped Spain to smooth out the required external adjustment process resulting from balance of payments shocks.  相似文献

Using Remote Sensing for Agricultural Statistics   总被引:7,自引:0,他引:7  
Remote sensing can be a valuable tool for agricultural statistics when area frames or multiple frames are used. At the design level, remote sensing typically helps in the definition of sampling units and the stratification, but can also be exploited to optimise the sample allocation and size of sampling units. At the estimator level, classified satellite images are generally used as auxiliary variables in a regression estimator or for estimators based on confusion matrixes. The most often used satellite images are LANDSAT-TM and SPOT-XS. In general, classified or photo-interpreted images should not be directly used to estimate crop areas because the proportion of pixels classified into the specific crop is often strongly biased. Vegetation indexes computed from satellite images can give in some cases a good indication of the potential crop yield.  相似文献

Fighting poverty is an important concern in most societies. This usually involves transferring resources to the poor. There exists a widespread view that European countries are much more generous to the poor than the United States. We study whether this is really the case. First, we argue that using data on aggregate spending does not allow us to conclude who the final recipients of social expenditure are. We then analyze microeconomic evidence from the Current Population Survey and the European Community Household Panel and find mixed results. In particular, when the concept of relative poverty is used, we find that every individual below the poverty line receives an average transfer in the United States that is 45% higher than in the European Union. When the old are excluded from the sample, this difference is reduced to 14%.  相似文献

A unified theory of structural change   总被引:2,自引:0,他引:2  
This paper uses dynamic general equilibrium and computational methods, inspired by the multi-sector growth model structure in Stephen Turnovsky's work, to develop a theory that unifies two of the traditional explanations of structural change: sector-biased technical change and non-homothetic preferences. The theory is based on an overlapping-generations growth model with endogenous technical change and non-homothetic preferences. An expanding-variety setup with two different R&D technologies, agricultural, and non-agricultural, is employed. The analysis, based on numerical simulations, shows that the biased technical change hypothesis finds most support in the data. It also points to production-side specific factors, such as asymmetries in cross-sector knowledge spillovers, as explanatory factors of the bias in technical change.  相似文献

A novel approach to analyzing real exchange rate (RER) persistence and its sources is presented. Using highly disaggregated data for a group of EU-15 countries, it is shown that the distribution of sectoral persistence is highly heterogeneous and skewed to the right, so that a limited number of sectors are responsible for the high levels of persistence observed at the aggregate level. Quantile regression has been employed to investigate whether traditional theories, such as the lack of arbitrage due to nontradability or imperfect competition combined with price stickiness, are able to account for the slow reversion to parity of RERs.  相似文献
