Innovation and integration in the agri-food industry

We deal with the link between innovation and market structure using the empirical example of the Danish agri-food industry. Vertical integration may resolve hold-up problems and here we test for the importance of vertical integration and networks on innovation. We further examine the effects of network relationships on innovation behaviour. We use data from an extensive survey of 444 Danish firms over two years, 2000 and 2005 to estimate a bootstrapped zero-inflated Poisson regression model. The first and most significant result is that organization matters. Further we find that vertical integration as well as contractual arrangements are significant determinants for firms’ innovation behaviour. The direction of integration is important as well. Also, economies of size seem to play an important role. Similarly, the export orientation of the firm is a significant determinant of innovation whereas the sector the firm is operating in is not significant for its innovation behaviour.     

Challenges and directions in knowledge asset trading

This paper addresses the area that is at the intersection of knowledge management and electronic commerce. This area refers to the exchange and trade of explicit and implicit knowledge at an inter‐organizational level. Electronic knowledge marketplaces are currently emerging to address the opportunities and risks found in the purchase and selling of knowledge in the business‐to‐business (B2B) environment, the need for supporting long‐lasting relationships of knowledge exchange and the requirement for facilitating virtual community contexts where knowledge seekers can find suitable knowledge providers and knowledge providers can advertise and sell their available knowledge. The paper describes the business challenges associated with the design of an Internet‐based knowledge marketplace. INKASS, a European IST project, has stimulated this work and has provided real‐life verification on the arguments raised and on the positions adopted herein.

Product line extensions: causes and effects

In this paper, and using data from a sample of five US manufacturing industries, we study the implications of market demand growth on product line extensions and the effects of the latter on industry profit margins. Companies extend their product lines in response to expansions in market demand and this tends to depress profit margins in the industry. Finally, these results are quantitatively significant.

Temporary layoffs and split population models

This paper develops and estimates a split population model for the duration of temporary layoffs in the German labour market; the population being split according to whether a layoff is temporary or permanent. A flexible piecewise constant hazard is employed and the recall propensity is used to condition the duration of a temporary layoff. The distinction between factors that influence the recall propensity and factors that influence the duration of a temporary layoff is shown to be of empirical significance. The results of the paper are used to evaluate implicit contract and search theories of temporary layoffs. The paper suggests that implicit contracts can explain the behaviour of unemployed workers with high worker–firm attachment whilst search can explain the behaviour of workers with low worker–firm attachment.

Volunteer tourism: at the crossroads of commercialisation and service?

Volunteer tourism as a phenomenon and as a market has come a long way since its ideologically driven early days. It is now an established and ever commercialised market that meets the demand for a different travel experience for the more morally conscious traveller, while at the same time it provides opportunities for economic gain for the organisations that act as brokers of such experiences. This interaction raises several ethical issues in terms of serving a mission while making economic gains. In general, there is an acceptable relationship between monetary gain and altruistic service, within the context of enlightened self-interest provided that the beneficiary of economic gains diverts profits into serving their mission. This paper examines the supply for volunteer tourism for evidence of commercialisation and profit-driven behaviour and investigates a relationship between monetary gain and serving a mission by creating public goods.     

Adjusting to skill shortages in Australian SMEs

Skill shortages are often portrayed as a major problem for advanced economies, yet there is surprisingly little empirical evidence about how firms adjust to skill shortages and their associated effects on firm performance. This article provides new evidence from the Business Longitudinal Database, an Australian data set with unusually rich information on the causes and consequences of skill shortages in small- and medium-sized enterprises. We document the range of alternative strategies that firms adopt when responding to skill shortages and show that certain types of adaptation are used in some cases and not in others, depending on the type of shortage encountered and other attributes of the firm. Further, we show that certain types of skill shortage are more likely to be long-lasting and difficult to resolve, while others are alleviated relatively quickly with minimal adjustment. Our findings yield lessons for the skill utilization strategies of firms and for the labour market policies of governments.
