Driving Trucks and Driving Sales? The Impact of Delivery Personnel on Customer Purchase Behavior

This study investigates how and under what conditions delivery persons, specifically truck drivers of a supplier firm, affect customers’ purchase behavior in industrial customer–supplier relationships. Drawing on service quality and customer contact literature, we test a proposed theoretical model that suggests a positive direct effect of personal contact quality (provided by a delivery person) on sales as well as three situational constraints that determine the occurrence and strength of the direct effect.     

Decentralized Taxation and the Size of Government: Evidence from Swiss State and Local Governments

According to the Leviathan Model, fiscal federalism is a binding constraint on revenue‐maximizing government. The competitive pressure of fiscal federalism reduces public sector size, as compared to unitary states. This study uses panel data of Swiss cantons from 1980 to 1998 to empirically analyze the effect of different instruments on government revenue and its structure. Because of the considerable tax autonomy of sub‐national Swiss governments, it is possible to investigate different mechanisms by which fiscal federalism may influence government size. The results indicate that tax exporting has a revenue‐expanding effect; whereas, tax competition favors a smaller size of government. Fragmentation has no robust effect on the size of government revenue for Swiss cantons. The overall effect of revenue decentralization leads to fewer tax revenues but higher user charges. Thus, revenue decentralization favors a smaller size of government revenue and shifts government revenue from taxes to user charges.     

Institutional drivers of conformity – Evidence for management accounting from Brazil and Germany

This paper contributes to the discussion of international convergence in management accounting, which has included only limited empirical data. Building on institutional theory, we have analysed cross-sectional field study data from a unique set of manufacturing companies in Brazil and Germany. Our data suggest that management accounting structures and practices in both countries are converging towards international standards under the pressure of coercive, mimetic and normative isomorphism. Although firms generally tend to adopt Anglo-American practices, we also find that German management accounting concepts have a strong influence in Brazil. In addition to elaborating on the imitation of international best practices and standardised information systems, we show the pressures created by the adoption of the International Financial Reporting Standards and the pursuit of legitimacy via adherence to social expectations.

Model averaging in risk management with an application to futures markets

This paper considers the problem of model uncertainty in the case of multi-asset volatility models and discusses the use of model averaging techniques as a way of dealing with the risk of inadvertently using false models in portfolio management. Evaluation of volatility models is then considered and a simple Value-at-Risk (VaR) diagnostic test is proposed for individual as well as ‘average’ models. The asymptotic as well as the exact finite-sample distribution of the test statistic, dealing with the possibility of parameter uncertainty, are established. The model averaging idea and the VaR diagnostic tests are illustrated by an application to portfolios of daily returns on six currencies, four equity indices, four ten year government bonds and four commodities over the period 1991–2007. The empirical evidence supports the use of ‘thick’ model averaging strategies over single models or Bayesian type model averaging procedures.     

Evaluating the effects of farm programmes: results from propensity score matching

The paper applies a semi-parametric propensity score matchingapproach to evaluate the effects of agri-environment (AE) programmeson input use and farm output of individual farms in Germany.The analysis reveals a positive and significant treatment effectof AE programmes on the area under cultivation, in particulargrassland, resulting in a decrease of cattle livestock densities.Furthermore, participation significantly reduced the purchaseof farm chemicals (fertiliser, pesticide). We also find differencesin the treatment effect among individual farms (heterogeneoustreatment effects). Farms that can generate the largest benefitfrom the programme are most likely to participate.     

Impacts of increased bioenergy demand on global food markets: an AgMIP economic model intercomparison

Integrated Assessment studies have shown that meeting ambitious greenhouse gas mitigation targets will require substantial amounts of bioenergy as part of the future energy mix. In the course of the Agricultural Model Intercomparison and Improvement Project (AgMIP), five global agro‐economic models were used to analyze a future scenario with global demand for ligno‐cellulosic bioenergy rising to about 100 ExaJoule in 2050. From this exercise a tentative conclusion can be drawn that ambitious climate change mitigation need not drive up global food prices much, if the extra land required for bioenergy production is accessible or if the feedstock, for example, from forests, does not directly compete for agricultural land. Agricultural price effects across models by the year 2050 from high bioenergy demand in an ambitious mitigation scenario appear to be much smaller (+5% average across models) than from direct climate impacts on crop yields in a high‐emission scenario (+25% average across models). However, potential future scarcities of water and nutrients, policy‐induced restrictions on agricultural land expansion, as well as potential welfare losses have not been specifically looked at in this exercise.     

Improving earnings quality: The effect of reporting incentives and accounting standards

We investigate the different effects on earnings quality of accounting standards and reporting incentives for Germany over the period 1994 to 2005. To this end, we control for reporting incentives at the firm level, instead of the country level, by using the timing of voluntary IFRS adoption as a proxy for reporting incentives. We then include reporting incentives in an analysis of earnings management and information asymmetry. Contrary to common expectation, we find that IFRS reporting potentially decreases earnings quality on average; but also that reporting incentives appear to have lower effects on earnings quality in IFRS statements than in GGAAP statements. Thus, IFRS may lead to more homogenous earnings quality across firms.
