Why do global long‐term scenarios for agriculture differ? An overview of the AgMIP Global Economic Model Intercomparison

Recent studies assessing plausible futures for agricultural markets and global food security have had contradictory outcomes. To advance our understanding of the sources of the differences, 10 global economic models that produce long‐term scenarios were asked to compare a reference scenario with alternate socioeconomic, climate change, and bioenergy scenarios using a common set of key drivers. Several key conclusions emerge from this exercise: First, for a comparison of scenario results to be meaningful, a careful analysis of the interpretation of the relevant model variables is essential. For instance, the use of “real world commodity prices” differs widely across models, and comparing the prices without accounting for their different meanings can lead to misleading results. Second, results suggest that, once some key assumptions are harmonized, the variability in general trends across models declines but remains important. For example, given the common assumptions of the reference scenario, models show average annual rates of changes of real global producer prices for agricultural products on average ranging between ?0.4% and +0.7% between the 2005 base year and 2050. This compares to an average decline of real agricultural prices of 4% p.a. between the 1960s and the 2000s. Several other common trends are shown, for example, relating to key global growth areas for agricultural production and consumption. Third, differences in basic model parameters such as income and price elasticities, sometimes hidden in the way market behavior is modeled, result in significant differences in the details. Fourth, the analysis shows that agro‐economic modelers aiming to inform the agricultural and development policy debate require better data and analysis on both economic behavior and biophysical drivers. More interdisciplinary modeling efforts are required to cross‐fertilize analyses at different scales.     

Smallholders,institutional services,and commercial transformation in Ethiopia

This article examines the role of institutional services of credit, input supply, and extension in the overall commercial transformation process of smallholder agriculture in Ethiopia. Survey data collected in 2006 from 309 sample households in three districts of Ethiopia are used for the analyses. Tobit regression models are used to measure the effect of access to services on the intensity of inputs use for fertilizer and agrochemicals. A probit model is used to measure these effects on the adoption of improved seeds. Intensity of use of seeds is analyzed using an ordinary least squares model. Logarithmic Cobb–Douglass functions are estimated to analyze the effect of access to services on crop productivity. Heckman's two‐stage estimation is used to examine determinants of household market participation and the extents of participation. Results show that access to institutional support services plays a significant role in enhancing smallholder productivity and market orientation. Our results imply that expanding and strengthening the institutional services is critical for the intensification and market orientation of smallholder agriculture in Ethiopia. In particular, appropriate incentives and regulatory systems are urgently needed to encourage the involvement of the private sector in the provision of agricultural services.     

Moral Emotions and Ethics in Organisations: Introduction to the Special Issue

The aim of our special issue is to deepen our understanding of the role moral emotions play in organisations as part of a wider discourse on organisational ethics and morality. Unethical workplace behaviours can have far-reaching consequences—job losses, risks to life and health, psychological damage to individuals and groups, social injustice and exploitation and even environmental devastation. Consequently, determining how and why ethical transgressions occur with surprising regularity, despite the inhibiting influence of moral emotions, has considerable theoretical and practical significance to management scholars and managers alike. In this introduction, we present some of the core arguments in the field; notably, the effect of organisational life and bureaucracy on emotions, in general, and moral emotions, in particular; the moral standing of leaders, managers and followers; moral challenges raised by obedience and resistance to organisational power and ethical blindspots induced by what may appear as deeply moral emotions. These issues are explored by a collection of geographically diverse articles in various work contexts, which are thematically organised in terms of (i) moral emotions, ethical behaviour and social pressure, (ii) moral emotions and their consequences within/across levels of analysis, (iii) psychoanalytic perspectives on the management of moral emotions, (iv) virtue and moral emotions and (v) moral emotions and action tendencies. We end by suggesting certain avenues for future research in the hope that the endeavour initiated here will inspire improved practice at work.

The Market Timing Ability of UK Mutual Funds

Abstract:  We apply a recent nonparametric methodology to test the market timing skills of UK equity and balanced mutual funds. The methodology has a number of advantages over the widely used regression based tests of Treynor-Mazuy (1966) and Henriksson-Merton (1981) . We find a relatively small number of funds (around 1%) demonstrate positive market timing ability at a 5% significance level while around 19% of funds exhibit negative timing and on average funds miss-time the market. However, controlling for publicly available information we find very little evidence of market timing ability based on private timing signals. In terms of investment styles, there are a small number of successful positive market timers amongst Equity Income and 'All Company' funds but not among either Small Stock funds or Balanced funds, although a few small stock funds are found to time a small stock index rather than a broad market index.

Noise fit,estimation error and a Sharpe information criterion

When the in-sample Sharpe ratio is obtained by optimizing over a k-dimensional parameter space, it is a biased estimator for what can be expected on unseen data (out-of-sample). We derive (1) an unbiased estimator adjusting for both sources of bias: noise fit and estimation error. We then show (2) how to use the adjusted Sharpe ratio as model selection criterion analogously to the Akaike Information Criterion (AIC). Selecting a model with the highest adjusted Sharpe ratio selects the model with the highest estimated out-of-sample Sharpe ratio in the same way as selection by AIC does for the log-likelihood as a measure of fit.     

University patenting and technology commercialization – legal frameworks and the importance of local practice

The impact of national legislative frameworks on the higher education sector's contribution to technological innovation is heavily disputed. This paper argues that legislative frameworks may stimulate the development of local practices for the management and exploitation of intellectual property (IP), which in turn determine the level of academic patenting. We present case studies of two comparable universities in each of four selected European countries with different histories of national IP legislation. A within-country analysis shows that a wider range and earlier development of local IP management and exploitation practices are accompanied by higher levels of academic patenting, and that increasing similarity of IP practices is associated with decreasing differences in patenting outputs. A preliminary cross-country analysis reveals an expansion in and increasing similarity of practices for IP management and exploitation in countries with different national IP framework histories. We conclude that adopting Bayh-Dole-like legislation may trigger the development of local IP practices, which stimulate patenting. However, it is not always sufficient and definitely not always necessary. The study concludes with some policy recommendations.     

Ethical reasoning in business‐to‐business negotiations: evidence from relationships in the chemical industry in Germany

This article explores managers’ ethical reasoning for behaviors in price negotiations using evidence from 15 in‐depth interviews conducted with sales and purchasing representatives in the chemical industry in Germany. Applying transaction cost economics, we find that negotiators in commoditized market‐like exchanges either refer to deontological norms such as not to lie, or they neglect a role for ethics, arguing that distributive negotiation is per se opportunistic. In contrast, exchanges of products with higher asset specificity lead to stronger informational integration which is supported with teleological justifications. Some negotiators use teleological justification to build business on trust rather than on economic safeguards as their firm norms would require. For negotiators, our results suggest considering institutional context and adjusting ethical reasoning to the negotiation situation. Firms need to recognize and find ways to address the potential conflicts of their internal norms with their frontline managers’ attempts to act in the firms’ best economic and ethical interests.
