Sustainability indicators,alternative strategies and trade-offs in peasant agroecosystems: analysing 15 case studies from Latin America

In view of the urgent need to improve agroecosystem sustainability, several efforts have been made to evaluate the effect of alternative strategies on key environmental and socioeconomic variables at the farm, community and regional levels. Most peasant farmers manage complex and diverse agroecosystems, and constantly adapt management strategies with multiple aims. A sustainability evaluation framework for peasant systems has been applied in over 40 case studies in Latin America, from which 15 were analysed, focusing on the choice of indicators, the effect of alternative strategies on agroecosystem sustainability and the trade-offs involved. Common indicators include yields, income, agrodiversity and external input dependence. Alternative strategies include crop/product diversification and soil conservation practices. Yields, income and agrodiversity improved in most cases, but in some cases the establishment costs increased external input use. Trade-offs observed include improved performance of a subsystem (i.e. crops) vs. decreased one in others (livestock, forestry) and increases in productivity vs. decreases in stability, resilience and reliability. The difficulty of assessing systems in transition towards alternative management was acknowledged by some evaluation teams. Applying the framework to such a variety of cases allowed making the sustainability concept operational, promoted alternative strategies and generated knowledge on agroecosystem processes among stakeholders.     

Witty invention or dubious fad? Using argument mapping to examine the contours of management fashion

This paper examines management fashion discourse based on the premise that management fashions are not neutral, but problematic. It grounds this premise on Abrahamson and Fairchild's (1999) observation that attributes the upswings of management fashion discourse to “emotionally charged, enthusiastic and unreasoned discourse”. Adopting this critical perspective, the paper conducts a careful analysis of faddish discourse in an attempt to understand the discursive ailments that would justify ascribing a diagnosis of “unreasoned” to this discourse. To achieve this goal, the paper employs the technique of argument mapping to examine and compare the structures of early discourse surrounding: (1) Business Process Reengineering (BPR) – typically now considered a fad; (2) Enterprise Resource Planning (ERP) – an enduring, non-faddish IS discourse; and (3) Service Oriented Architecture (SOA) – a more recent discourse that is evaluated based on insights derived from comparisons of BPR and ERP. Findings from the resultant argument maps show conspicuous differences between BPR and ERP argumentation, which suggests an association between early argument structure and the faddish trajectory of discourse. Similarly, insights derived from ERP and BPR argument comparisons suggest that SOA is more likely to follow the faddish course of its BPR predecessor rather than the enduring track of ERP.     

The determinants of tax morale in comparative perspective: Evidence from European countries

Applying a multilevel model, we argue that tax morale is a function of individual- and contextual-level variables. Evidence presented in this article, based on the 2004–2005 European Social Survey and information on institutional settings, shows that tax morale in European countries varies systematically with socio-demographic characteristics, personal financial experiences, political attitudes, on the one hand, and regional GDP and tax arrangements on the other hand. Moreover, cross-national differences in tax morale are also related to ethnic and linguistic fractionalizations.     

The impact of food inflation on urban poverty and its monetary cost: some back‐of‐the‐envelope calculations

This article uses a sample of 72 developing countries to estimate the change in the cost of alleviating urban poverty brought about by the recent increase in food prices. This cost is approximated by the change in the poverty deficit (PD), that is, the variation in financial resources required to eliminate poverty under perfect targeting. The results show that, for most countries, the cost represents less than 0.2% of gross domestic product. However, in the most severely affected, it may exceed 3%. In all countries, the change in the PD is mostly due to the negative real income effect of those households that were poor before the price shock, while the cost attributable to new households falling into poverty is negligible. Thus, in countries where transfer mechanisms with effective targeting already exist, the most cost‐effective strategy would be to scale up such programs rather than designing tools to identify the new poor.     

A mark-up pricing model for price simulations

This paper develops an input/output model of pricing using a mark-up pricing formula. The connection between mark-up pricing and competitive pricing is analyzed through the determination of sectoral equilibrium profit mark-up rates as a function of the profit rate and the capital intensity of each sector. The model is used to analyze the effects on relative prices and the aggregate price level of exogenous changes in the nominal wage rate, tax rates, the exchange rate and world prices. Exogenous changes in the prices of domestically produced commodities are modelled via the imposition of ad valorem tax rates, which yield a measure of the net effect of the exogenous changes. Simulations are carried out under passive price adjustment as well as adjustment with price ceilings. In this last instance the model calculates the endogenously determined reduction in profit mark-ups. Lastly, empirical results of various simulations are presented using data from the Mexican economy.     

Evidence of Differences in the Effectiveness of Safety-Net Management in European Union Countries

European Union (EU) financial safety nets are social contracts that assign uncertain benefits and burdens to taxpayers in different member countries. To help national officials to assess their taxpayers’ exposures to loss from partner countries, this paper develops a way to estimate how well markets and regulators in 14 of the EU-15 countries have controlled deposit-institution risk-shifting in recent years. Our method traverses two steps. The first step estimates leverage, return volatility, and safety-net benefits for individual EU financial institutions. For stockholder-owned banks, input data feature 1993–2004 data on stock-market capitalization. Parallel accounting values are used to calculate enterprise value (albeit less precisely) for mutual savings institutions. The second step uses the output from the first step as input into regression models of safety-net benefits and interprets the results. Parameters of the second-step models express differences in the magnitude of safety-net subsidies and in the ability of financial markets and regulators in member countries to restrain the flow of safety-net subsidies to commercial banks and savings institutions. We conclude by showing that banks from high-subsidy and low-restraint countries have initiated and received the lion’s share of cross-border M&A activity. The efficiency, stabilization, and distributional effects of allowing banks to and from differently subsidized environments to expand their operations in partner countries pose policy issues that the EU ought to address.     

Enjoy the silence: an experiment on truth-telling

We analyze experimentally two sender–receiver games with conflictive preferences. In the first game, the sender can choose to tell the truth, to lie, or to remain silent. The latter strategy is costly. In the second game, the receiver must decide additionally whether or not to costly punish the sender after having observed the history of the game. We investigate the existence of two kinds of social preferences: lying aversion and preference for truth-telling. In the first game, senders tell the truth more often than predicted by the sequential equilibrium analysis, they remain silent frequently, and there exists a positive correlation between the probability of being truthful and the probability of remaining silent. Our main experimental result for the extended game shows that those subjects who punish the sender with a high probability after being deceived are precisely those who send fewer but more truthful messages. Finally, we solve for the Perfect Bayesian Nash Equilibria of a reduced form of the baseline game with two types of senders. The equilibrium predictions obtained suggest that the observed excessive truth-telling in the baseline game can be explained by lying aversion but not by a preference for truth-telling.

海关估价与转移定价

当涉及货物的估价问题时,海关估价的考虑与所得税方面的考虑是矛盾的。进口商倾向于采用较低的海关价格以便少缴关税,但大多数时候由于所得税的原因,也希望同样货物采用较高的价格（比如高的转移价格）,以便降低利润从而缴纳较低的所得税。     

The Ethical Dimension of Leadership in the Programmes of Total Quality Management

Total Quality Management (TQM) is an overall management philosophy that includes a set of principles whose application is increasing. In fact, the business world and public institutions, such as hospitals, universities or city councils, are implementing quality programs. However, despite the wide diffusion of TQM, the success rate of this type of initiative is limited and the results, heterogeneous. Academics and professionals are therefore trying to identify the keys that explain the success or failure of this kind of initiative. Different explanations have been given, but most of the literature agrees that managerial commitment, implication and leadership are indispensable elements in a successful implementation of TQM. Nevertheless, a study on the specialised literature shows a terminological confusion between managerial commitment and managerial leadership. Is it the same to have a committed manager in the implementation process as to have a leader of the implementation process? The author of this paper defends the thesis that "commitment" and "leadership" are not synonymous, and states that only managerial leadership is able to promote and sustain profound organisational changes. The paper will show that, to understand the previous distinction, it is necessary to consider the ethical dimension of leadership. While committed managers may lead the process by using exclusively their power (with the necessary resource assignment), those who are leaders need authority. Authority goes further than power by generating a kind of confidence (trust) that is able to influence the members of the organisation and bring about profound changes, more than power alone can do.     

Airline website loyalty formation and the moderating effects of gender and education

The objective of this study is to analyse the moderating effects of gender and education on users’ loyalty to the website of an airline. We provide a tested model for greater understanding the effects of gender and education on the loyalty of experienced users in utilitarian purchasers of airline’s website. The results reveal that website quality, e-satisfaction, e-trust and affective e-loyalty are antecedents of conative e-loyalty in loyalty relationships between passengers and airline websites, as well as the importance of university education in the configuration of loyalty to the website. Consumers with university education are found to be more likely to purchase through the websites of airline companies than those without. Also, according to the most recent literature, the moderating effect of gender has been found non-significant in most of the causal relationships presented in the model studied.
