Representation in UK Employment Tribunals: Analysis of the 2003 and 2008 Survey of Employment Tribunal Applications (SETA)

The perception is that formal representation is increasingly common in UK Employment Tribunals (ETs), as case volumes and complexity increase. We investigate the nature of representation in UK ETs using the 2003 and 2008 Survey of Employment Tribunal Applications (SETA). The results suggest that between 2003 and 2008, the extent of formal claimant representation declined. The majority of employers and claimants are either heavily represented or have little/no representation, and there is little evidence that claimant representation is a response to employer representation at least at the level of individual claims. Overall, however, it would seem that some of the ‘accessible, informal and inexpensive’ characteristics envisaged by Donovan continue to apply only to cases within certain jurisdictions.

Summary This paper gives an empirical reexamination of the Linear-Expenditure-hypothesis for Austria. It starts with a brief theoretical discussion of the principal properties and restrictions of the Linear-Expenditure-System (LES). To obtain empirical estimates of the parameters of the LES two different estimation procedures are applied, i.e. the original method used byStone and a simplified version of the Systems-Least-Squares-approach (following theMarquardt-algorithm). There are no essential differences between these estimates. They all seem plausible and satisfy the theoretical restrictions.Usually the stability (i.e. time-invariance) of the parameters is accepted without proof. Using the Moving-Window-Regression-technique, however, most of the estimates vary significantly in time. To obtain a direct proof of the time-dependence of the parameters the LES is reestimated now including trend-factors. Especially results considering time-dependent marginal-budget-shares are considerably better than the static-model results.The conclusion of this paper is that the static version of the LES does not explain the consumer behaviour in Austria and that much more effort should be spent on the estimation of dynamic demand systems.     

The effects of policy funds on the financing constraints of small- and medium-sized enterprises in South Korea

This study investigates whether small- and medium-sized enterprises (SMEs) policy funds in South Korea are effective in reducing financing constraints faced by the SMEs. We find that investment-cash flow sensitivity decreases after public loans are granted, and furthermore that this decrease in the sensitivity is greater for younger and smaller firms. These results are consistent with the certification effects hypothesis.     

The sky is the limit? The determinants and constraints of European airports commercial revenues

This study investigates the determinants of commercial and retail airport revenues from real estate operations. Aviation revenues per passenger are mainly determined by the national income per capita in the area where the airport is located, the percentage of leisure travelers and the size of the airport. Main drivers of commercial revenues per passenger include the number of passengers passing through the airport, the ratio of commercial to total revenues, national income, the share of domestic and leisure travelers and the number of flights. These results are in line with previous findings of a negative influence of business travelers on commercial revenues per passenger. We also find that a large amount of retail space per passenger is generally associated with lower commercial revenues per square meter confirming decreasing marginal revenue effects. Real estate revenues per passenger are positively associated with national income per capita at airport location, share of intra-EU passengers and percent delayed flights.     

Sustainability evaluation of rapid routes for buses with a network DEA model

This study establishes a network data envelopment analysis (DEA) model to evaluate the sustainability of public transportation services targeting rapid routes for buses in the Seoul metropolitan area. A network DEA-based optimization model is formulated to evaluate the sustainability of the public transportation service. By considering public transportation services from both the operators’ and users’ perspectives, this model produces results that reflect the interaction of three sustainable transport service properties, i.e., efficiency, equity, and environmental impacts. It is identified that the expansion of median bus lanes and the conversion of conventional buses into compressed natural gas vehicles could improve the sustainability of the public transportation services in the Seoul metropolitan area. Some limitations and future research agenda also are presented.     

EU-China Partenariat 2006:Tailor-made Opportunities for SMEs of EU and China

2006 EU-China Partenariat 2006, the large-scale business-to-business event which will link almost one thousand European and Chinese companies is indeed a highly appropriate way to further enhance the already excellent relations between the EU and China moreover as this is the very year that we are celebrating 30 years of EU-China diplomatic ties.……
