Testing for Intermediate Outputs in Dynamic DEA Models: Accounting for Soil Capital in Rotational Crop Production and Productivity Measures

Inagricultural production, a stylized fact known as the rotationeffect says crop rotations generate higher yields or productivitythan identical crops grown in isolated monocultures. This paperdevelops a dynamic data envelopment analysis (DEA) model of cropproduction that accounts for the rotation effect. The model isapplied to data from an experimental farm in Pennsylvania toinvestigate the role soil capital plays in observed productivitygrowth and the rotation effect.     

Productivity,Infrastructure and Human Capital in the Spanish Regions

We revisit the cointegration relation among output, physical capital, human capital, public capital and labour for 17 Spanish regions observed over the period 1964–2011. Our approach is based on the estimation of a panel data model where cross-section dependence is allowed among the members of the panel. The paper emphasizes the idea that common factors capturing, for instance, total factor productivity, should be accounted for when estimating the parameters. We use several proposals to estimate the long-run relation among these variables, which render consistent and efficient estimates of the parameters.     

Some Remarks on Productivity and its Decompositions

This paper provides a brief history of the Malmquist productivity index and its decomposition. Theoretical and empirical issues related to the index are discussed along with directions for future research.     

Productivity change in a multisectoral economic system

We estimate productivity growth without recourse to data on factor input shares or prices. In the proposed model, the economy is represented by the Leontief input–output model, which is extended by the constraints of primary inputs. A Luenberger productivity indicator is proposed to estimate productivity change; this is then decomposed in a way that enables us to examine the contributions of individual production factors and individual commodities to productivity change. The results allow for the identification of inputs or outputs that are the drivers of the overall productivity change. Their contributions are then decomposed into efficiency change and technical change components. Using input–output tables of the US economy for the period 1977–2006, we show that technical progress has been the main source of productivity change. Technical progress was mostly driven by capital, whereas low-skilled labour contributed negatively.     

The next generation of workers in Australia: their views on organizations,work and rewards

This study draws upon a small sample of university students in Australia to investigate how organizational preferences are related to different attitudes about work and reward. It extends past sectoral research to analyse both sectoral and organizational differences, and looks beyond individuals who are working in the sectors and organizations, to those who aspire to enter the various sectors and organizations, and therefore is valuable for recruitment. Apart from a few exceptions, the respondents in this survey who intend to enter the different sectors in the near future appeared to be largely motivated by job attributes which are similar to those reported in past studies on the employees in these sectors.     

Government Consumption and Industrial Productivity: Scale and Compositional Effects

Within a production function framework in which government spending produces public goods which enter firms production functions, empirical tests using time series data spanning eleven countries and thirty industries find both the scale and the composition of government consumption spending to affect the level and the rate of growth of total factor productivity at the industry level.Jel Classification: H50, D24     

High‐performance work systems and creativity implementation: the role of psychological capital and psychological safety

Unimplemented creative ideas are potentially wasted opportunities for organisations. Although it is largely understood how to encourage creativity among employees, how to ensure this creativity is implemented remains underexplored. The objective of the current study is to identify the underlying mechanisms that explain the relationship between high‐performance work systems and creativity implementation. Drawing from the job demands–resources model, we explore a model of psychological capital and psychological safety as mediators in the relationship between high‐performance work systems and creativity implementation. Based on 505 employee survey responses, the findings show support for the mediating relationships, highlighting the importance of psychological mechanisms. The study has important implications for HRM, uncovering how people management practices can encourage creativity implementation in the workplace.     

Productivity Measurement from a Reference Technology: A Distance Function Approach

An approach to productivity measurement based on distance function measurement is developed in this paper. A series of reference technologies are constructed by augmenting observed inputs and outputs such that the resulting effective netputs are consistent with the weak axiom of profit maximization. Geometric means of year-ahead and year-back distance function values serve as measures of multifactor productivity changes. Both primal measures from the inner bound and dual measures from the outer bound of the reference technologies are calculated. Resulting productivity measures are similar to those derived using index number approaches, but potentially provide greater information regarding the reference technologies.

Input,Output, and Environmental Management Productivity: Effects on Firm Performance

Firms invest considerable resources to control any of their operations that may have environmental impacts in an attempt to reduce such impacts but also generate economic value. Various studies of the basic creation or destruction of monetary value through environmental performance offer contradictory evidence. Therefore, the present study proposes a new definition of environmental management as the transformation of inputs (resources assigned) into outputs (valuable results). Both inputs and outputs should be taken into account to explain financial outcomes; further consideration should also include a third aspect, namely, ‘environmental management productivity’, which describes the relationship between the outputs and inputs of environmental management. Empirical analyses of Spanish firms with a certified environmental management system subject to the European Union's CO₂ emissions trading system provide evidence that all three aspects must be considered in combination to achieve a more comprehensive view of the impact of environmental management on financial performance.

Product Market Competition,Skill Shortages and Productivity: Evidence from Canadian Manufacturing Firms

In this paper, we estimate the impacts of product market competition and skill shortages on the productivity level performance of Canadian manufacturing firms. We use firms perceptions of their competitive environment from the Statistics Canada 1999 Survey of Innovation to measure product market competition and skill shortages. We argue in the paper that such perceptions are important for productivity level performance. After controlling for other factors, we find that product market competition has a positive impact on the performance of medium-sized and large-sized firms, and that skill shortages have a negative impact on the performance of small-sized and medium-sized firms.Jel Classification: L0, O0     

Impact of Green Innovation on Labor Productivity and its Determinants: an Analysis of the Korean Manufacturing Industry

Due to worsening environmental conditions around the globe, firms have been investing a great deal of money in green technologies as a way of coping with the environmental crisis. This paper uses a unique data set based on the Korea Innovation Survey to examine the impact of green innovation on labor productivity, and the determinants of environmental activities in 2010. The empirical results show that green innovation intended for both firm and customer benefits has a positive effect on labor productivity. This finding means that firms need to implement firm‐oriented green innovation as well as customer‐oriented green innovation in order to increase their performance. Our findings also show that there are significant differences in aggregate green innovations depending on different firm sizes and industries. Specifically, large firms implement environmental activities more than small ones, and pollution‐intensive industries tend to invest more in activities related to environmental technology.

Employee ambidexterity,high performance work systems and innovative work behaviour: How much balance do we need?

Abstract

This study examines whether and how innovative work behaviour is related to explorative and exploitative activities. Polynomial regression analyses are used to test the relationship between ambidexterity (being engaged in explorative and exploitative activities in equal amounts) and innovative work behaviour, as well as between specialisation (being engaged in either explorative or exploitative activities) and innovative work behaviour. Furthermore, we use moderated polynomial regression analyses to examine a possible moderating effect of high-performance work systems (HPWS) on these relationships. Results indicate that balance at a high level, as well as specialisation, are conducive to innovative work behaviour. A moderating effect of HPWS was not supported by our data.     

The impact of diversity and equality management on firm performance: Beyond high performance work systems

This article demonstrates that a diversity and equality management system (DEMS) contributes to firm performance beyond the effects of a traditional high‐performance work system (HPWS), which consists of bundles of work practices and policies used extensively in high‐performing firms. A DEMS typically includes diversity training and monitoring recruitment, pay, and promotion across minority or other disadvantaged groups. Our analysis of quantitative data from service and manufacturing organizations in Ireland confirms that HPWS practices are associated with positive business performance and finds specifically that DEMS practices are positively associated with higher labor productivity and workforce innovation and lower voluntary employee turnover. © 2010 Wiley Periodicals, Inc.     

How and when matter: Exploring the interaction effects of high‐performance work systems,employee participation,and human capital on organizational innovation

Existing research on the relationship between high‐performance work systems (HPWS) and organizational innovation has paid insufficient attention to the boundary effects of employee participation and human capital. Bridging the human resource management (HRM) and employment relations literature, this study contributes to the contingency view of HRM and China‐specific research by investigating how human capital and employee participation, direct voice mechanism, and corporate governance participation jointly moderate the relationship between HPWS and organizational innovation. We test our three‐way interaction model using a sample of 108 firms and 1,250 employees in China. The results suggest that HPWS are positively associated with organizational innovation when employees with relatively less human capital are coupled with more direct voice mechanism or less corporate governance participation. In contrast, HPWS are negatively related to organizational innovation when employees possessing greater human capital are coupled with more direct voice mechanism. The theoretical and managerial implications and future research directions are discussed.     

External Interaction,Innovation and Productivity: An Application of the Innovation Value Chain to Ireland

Abstract

This paper analyses the innovation value chain for the Irish Community Innovation Survey (CIS): 2004–2006. In estimating innovation and productivity simultaneously, it extends the CDM methodology to include a range of external knowledge sources. Feedback effects are found to be vital, with more productive firms being more innovative and vice versa. External knowledge sources affect the innovation decision but not innovation performance, thus pointing to the primacy of internal processes for the crucial task of knowledge exploitation. There is evidence of dichotomous knowledge sourcing in Ireland, with some firms sourcing from market and others, especially high-technology businesses, from non-market agents.

External interaction, innovation et productivité extérieure: une application de la chaîne de valeur de l'innovation à l'Irlande

La présente communication analyse la chaîne de valeur d'innovation pour le CIS : 2004–2006 irlandais. En estimant l'innovation et la productivité simultanément, elle procède au développement de la méthodologie CDM, en incorporant un éventail de sources de connaissances extérieures. Il s'avère que les effets de la rétroaction sont essentiels, les entreprises les plus productives étant plus innovantes et vice-versa. Des sources de connaissances externes affectent les décisions sur l'innovation, mais non pas les performances de l'innovation, en soulignant ainsi l'importance primordiale des procédés internes pour la tâche essentielle de l'exploitation des connaissances. On a relevé des traces des sourçage dichotomique des connaissances en Irlande, certaines entreprises s'approvisionnant directement sur le marché, d'autres, notamment dans le secteur des technologies de pointe, s'inspirant d'agents extérieurs au marché.

Interacción, innovación y productividad externas: una aplicación de la cadena de valor de la innovación en Irlanda

En este trabajo se analiza la cadena de valor de la innovación de Irish CIS: 2004–2006. Al estimar simultáneamente la innovación y la productividad, se amplía la metodología CDM para abarcar una serie de fuentes externas de conocimiento. En este análisis se concluyó que los efectos de la realimentación son vitales, dado que más firmas productivas son más innovadoras y viceversa. Las fuentes externas de conocimiento afectan las decisiones de innovación y no el rendimiento asociado con la innovación y, por consiguiente, se señala el predominio de los procesos internos para la tarea crucial de explotación del conocimiento. En Irlanda, hay evidencias de obtención dicotómica del conocimiento, con algunas firmas que lo obtienen en el mercado y otras, en especial las empresas de alta tecnología, a través de agentes fuera del mercado.

     

Productivity,Technology and Economic Growth: What is the Relationship?

The relationship between productivity, technology and economic growth has been debated extensively in the endogenous growth, growth accounting, New Economy and policy literature. This paper briefly surveys the literature on total factor productivity (TFP) calculations – the various techniques and problems associated with it. We argue that TFP is not a measure of technological change and only under ideal conditions does it measure the supernormal profits associated with technological change. The critical driving force of economic growth is not the super normal profits that technological change generates but rather the continuous creation of opportunities for further technological development. Six illustrations of when TFP fails to correctly measure these super normal profits are provided. A version Carlaw and Lipsey's (2003b) model of endogenous general purpose technology‐ driven growth is then utilized to make some progress toward answering Prescott's (1998) call for a theory of TFP. The model is used to simulate artificial data and connect theoretical assumptions of returns to scale and resource costs to the conditions under which TFP miss‐measures the actual growth of technological knowledge.
