This paper reviews what has been learned from experiences of African agriculture and hence what policy lessons may be. Views of African agriculture over the last 130 years have changed from optimism to pessimism and at least halfway back again as the performance of the sector has fluctuated. Fortunately it seems the deep pessimism about agricultural prospects expressed in the 1980s and 1990s has receded. The performance of African agriculture since 1990 suggests that neither those who doubt that any significant advances are taking place, nor those who see advances in some remarkable but perhaps isolated cases of rapid transformation of farming and agricultural supply chains, have sufficient evidence – either from national data or small‐scale studies – to support their positions. Hence policy has to rely largely on general principles and historic lessons, rather than more clearly proven propositions. Policy debates over African agricultural development may sharply divide on some topics, but there is little debate over the importance of basic conditions for agricultural development of an enabling investment climate and the provision of rural public goods. Beyond these basics, the challenge is to remedy the failings of markets that deny most smallholders access to inputs, financial services and insurance. Here opinion divides between whether to return to public provision, as with fertiliser subsidies, or whether private and collective institutional innovations will be sufficient. Recent initiatives to test and scale up the latter look promising, but most have yet to be evaluated. If agricultural development is first and foremost about establishing the basic conditions for growth, then most countries in Africa may be better placed than they have been in the past. Given the many examples that show African smallholders investing and innovating when they have the chance, then there are reasons to hope that the modest growth of production and productivity seen in the last two decades may accelerate in the future – thereby allowing African countries to make the transition from agrarian to urban economies.  相似文献

This article provides new evidence on the effect of changes in employment protection on worker absence. We use novel multi‐organization data to examine changes in worker absence as workers move from temporary to permanent employment contracts. We demonstrate a robust positive effect of employment protection on sickness absence. It has also been suggested that the impact of employment protection on absence and effort is due to a fear of dismissal. We also provide evidence that suggests that temporary workers' absence is influenced by incentives to attain jobs with protection that is unrelated to threat of dismissal. This has not been considered in earlier research. This channel of employment protection effects has important policy implications.  相似文献

This study tests five potential drivers underlying the acceptance of SMS advertising. After developing a scale to measure behavioral responses to SMS advertising, the relationships between the acceptance of SMS advertising, intention to receive SMS advertising and behavioral responses to SMS advertising are tested. A convenience sampling method was employed. Survey questionnaires were distributed across Western Australia. The return yielded 203 usable questionnaires from the respondents. Several factors emerge as significant drivers of acceptance of SMS advertising including utility of SMS advertisements, context of SMS advertisements and attitudes to advertising in general. Contrary to expectation, control over SMS advertisements did not emerge as a significant driver for acceptance of SMS advertising. Trust in advertisers and laws did not emerge as a significant driver of the acceptance of SMS advertising among Australian respondents. Advertisers who pursue consumer acceptance should strive to build utility and context considerations into their SMS campaigns. Future research opportunities include testing the drivers of SMS advertising to further investigate the impact of control and trust on acceptance of SMS advertising in other countries where the SMS advertising has not been explored yet.  相似文献

Through a case study contrasting the impacts of formalised and informal teleworking practices on office‐based workers, multidimensional dilemmas between flexibility, control and equity are uncovered. Formal schemes, although problematic and rare, possess some advantages in resolving the three dimensions. A model is proposed to test findings further.  相似文献

One of the primary objectives of both adoption of IFRS and convergence between IFRS and U.S. GAAP is to increase financial statement comparability. Using a unique setting in Germany, we compare the effectiveness of these two approaches in achieving this desired outcome. Our empirical tests show that both adoption and convergence lead to an increase in comparability after the new enforcement regulation in 2005. However, difference‐in‐differences tests show that adoption does not lead to a significant incremental increase in comparability beyond convergence. The findings of this study should be of interest to regulators and standard setters as they assess alternative methods of aligning domestic standards with IFRS.  相似文献

Theory and policy relating to labor markets is dominated by the mainstream labor market model, although a less well-known, socioeconomic version can also be identified. The mainstream model is methodologically flawed and forced, thereby, to relegate any (serious) investigation of labor market institutions and/or social structures to the margins of its analysis. The socioeconomic account is not so much methodologically flawed, as methodologically ambivalent. While this ambivalence does not actually prevent the investigation of institutions and/or social structures, it does promote ambiguity whenever we inquire into the precise nature of the interaction between them and labor markets. Insights from Austrian economics, when used in collaboration with critical realist methodology, can play a part in augmenting the socioeconomic account, generating a totally new approach to the analysis of labor markets.

This paper explores the issue of a simultaneous reduction in tariffs at different stages of a vertically related market where each stage is oligopolistic. When vertically related markets are characterized as a successive oligopoly, reducing tariffs by an equivalent amount on upstream and downstream imports will have a differential effect on market access and hence profits at each stage as a result of a combination of horizontal and vertical effects. These differential effects have implications for the tariff structure post‐trade reform.  相似文献

Promotional competitions remain underresearched with only limited conceptualization of campaign design (framing) options evident. Our research addresses the following questions: What are the specific framing options available to campaign planners? What framing strategies should decision-makers apply to optimize campaign performance against promotional aims and objectives? We analyze a sample of promotional competition campaigns in the Australian market to identify the range of specific framing options. We present a taxonomy of Action, Entry, and Prize choices, integrating the key promotional aims of economic, informational, and affective influence. Academic and practitioner implications are discussed and a future research agenda is proposed.  相似文献
