The requirement for small firms to collaborate, as a means to supplementing and complementing limited internal resources, has dominated much of the academic and policy debate on regional development and small firm innovation throughout the late 1980s and 1990s. However, relatively little empirical work has sought to look further than simple frequency enumeration - noting that the most innovative and better performing firms are generally more likely to have links with external organizations. Based upon a sample of 228 small West Midlands' manufacturers, this study considers the source, function, geography and strength of innovation-related co-operation. While the general findings point to innovators making greater use of external linkages, of certain types and in particular directions (notably the preponderance of vertical value chain linkages), the results are less emphatic than might have been anticipated. This leads to consideration of the factors contributing to and impeding joint innovation and the firms' perceptions of the impact of innovation. From this, it appears that much of the observed difference between innovators and non-innovators lies in less objective measures. The data suggest the importance of inter-personal dynamics, attitude and expectations in facilitating successful collaboration.  相似文献

  • Museums must maintain a steady membership base to achieve their organizational objectives. Although many studies look at why relationships succeed, we examine members who fail to transition from an introductory relationship to a mature relationship with an art museum. In two studies examining non‐renewing members of a large metropolitan art museum, we find evidence for a phenomenon we call “stalled” relationships, whereby members discontinue their formal museum membership yet maintain a positive psychological affiliation with the museum. Our first study finds that members in stalled relationships often do not view themselves as defectors and do not blame the museum for their non‐renewal; they frequently cite personal reasons rather than service failures for discontinuing their membership. Our second study examines this phenomenon in greater detail, exploring the antecedents for stalling and finds that motivations for initiating their membership may help predict when a relationship is likely to stall.

Detecting nonlinearity in time series by model selection criteria   总被引:1,自引:0,他引:1  
This article analyzes the use of model selection criteria for detecting nonlinearity in the residuals of a linear model. Model selection criteria are applied for finding the order of the best autoregressive model fitted to the squared residuals of the linear model. If the order selected is not zero, this is considered as an indication of nonlinear behavior. The BIC and AIC criteria are compared to some popular nonlinearity tests in three Monte Carlo experiments. We conclude that the BIC model selection criterion seems to offer a promising tool for detecting nonlinearity in time series. An example is shown to illustrate the performance of the tests considered and the relationship between nonlinearity and structural changes in time series.  相似文献

In this paper, I develop a regression-based system of labour productivity equations that account for capital-embodied technological change and I incorporate this system into IDLIFT, a structural, macroeconomic input-output model of the US economy. Builders of regression-based forecasting models have long had difficulty finding labour productivity equations that exhibit the "Solowian' property that movements in investment should cause accompanying movements in labour productivity. The production theory developed by Solow and others dictates that this causation is driven by the effect of traditional capital deepening as well as technological change embodied in capital. Lack of measurement of the latter has hampered the ability of researchers to estimate properly the productivity-investment relationship. Recent research by Wilson (2001) has alleviated this difficulty by estimating industry-level embodied technological change. In this paper, I utilize those estimates to construct capital stocks adjusted for technological change and then use these adjusted stocks to estimate Solow-type labour productivity equations. It is shown that replacing IDLIFT's former productivity equations, based on changes in output and time trends, with the new equations, results in a convergence between the dynamic behaviour of the model and that predicted by traditional (Solowian) production theory.  相似文献

Regional integration: an empirical assessment of Russia   总被引:1,自引:0,他引:1  
Using a statistical model of commodity trade, we quantify the evolution of regional economic integration within Russia during 1995–1999, and explore potential determinants of this evolution. Our integration measure exhibits rich regional variation that, when aggregated to the national level, fluctuates substantially over time. In accounting for this behavior, we draw in part on theoretical models that emphasize the potential role of openness to international trade and regional disparities in income in threatening economic integration. Controlling for a host of additional regional- and national-level variables, we find a strong negative correspondence between openness to international trade and internal economic integration.  相似文献

  • Very little systematic research has focused on applying the concept of intellectual capital (IC) within the nonprofit context; particularly in the highly competitive nonprofit environment. Based on a review of the existing literature, this paper firstly contributes to filling this gap by building an argument that IC can be utilised as a competitive tool in nonprofit organisations (NPOs). Secondly, an IC conceptual framework is proposed that explicitly links the attainment of competitive advantage with positive outcomes for NPOs. Finally, the paper discusses how the IC conceptual framework can be effectively utilised to foster competitive advantage in the nonprofit sector.

We present the first attempt to locate zero‐hour contract (ZHC) jobs—jobs that lack a guaranteed minimum number of hours—within theoretical frameworks of the employment relationship and occupational class and empirically explore their characteristics using successive UK Labour Force Survey. In line with these theories, we find this contentious form of employment to be strongly differentiated by the nature of occupational tasks and to overlap with nonstandard employment features (e.g. part‐time and temporary). They are also highly concentrated in a small number of occupations and sectors, with over half of ZHC jobs found in just 10 occupations. We further show that ZHCs are associated with indicators of inferior job quality such as low pay and underemployment. Although we find no evidence that ZHCs are a particularly pervasive feature of the UK labour market, further growth cannot be ruled out in certain occupations.  相似文献

Standard macroeconomic theory predicts rapid responses of asset prices to monetary policy shocks. Small‐scale vector autoregressions (VARs), however, often find sluggish and insignificant impact effects. Using the same high‐frequency instrument to identify monetary policy shocks, we show that a large‐scale dynamic factor model finds overall stronger and quicker asset price reactions compared to a benchmark VAR, both on euro area and US data. Our results suggest that incorporating a sufficiently large information set is crucial to estimate monetary policy effects.  相似文献

Advances in the study of both markets and platforms contribute to economics. Platforms are typically digital markets, although platforms can designate markets generally. So, the economics of markets and the economics of platforms are one and the same. Platforms show the critical role of intermediaries in endogenous price adjustment and market clearing. The platform model remedies problems with general equilibrium analysis by combining and extending the basic Walrasian and Marshalian market models. The analysis of platforms provides explanations for the bid–ask spread, including market power, search costs, matching costs, adverse selection, and moral hazard. The study of platforms demonstrates the importance of participation and coordination in the formation of markets. The discussion emphasizes that platforms have significant implications for the theory of the firm. The analysis further considers how platforms affect innovation and entrepreneurship.  相似文献

La revolución de las TIC ha generado un alto riesgo de deslocalización de las tareas más comercializables en el sector de los servicios. Se revisan aquí estudios que proponen indicadores de comerciabilidad de los servicios, exploran las implicaciones de su deslocalización y desarrollan modelos teóricos al respecto. Tanto el nivel de calificación requerido como la comerciabilidad podrían ser determinantes clave de los efectos sobre los salarios y el empleo. Sin embargo, la falta de definiciones consensuadas de comerciabilidad y de datos fiables sobre el comercio de servicios, junto con la dificultad de evaluar la competencia de las importaciones a niveles desagregados, obstaculizan el avance de los estudios empíricos y descubren áreas para futuras investigaciones.  相似文献
