The current policy debate on opportunities for African smallholders in agricultural markets focuses on the need for proper institutions at the market level or governance in the global value chain (GVC). Both discussions neglect insights from strategic management. We argue that successful inclusion of smallholders in GVCs requires the deployment of strategic resources and capabilities in the farming systems. The consequence of this argument is that the ‘inclusion’ of smallholders in GVCs only makes sense if they have the opportunity to create strategic resources. 相似文献

Helpman and Krugman (Market structure and foreign trade. Increasing returns, imperfect competition, and the international economy. MIT Press, Cambridge, 1985) provide a synthesis of the traditional factor proportions theory of international trade and the theory of international trade due to the exploitation of scale economies in imperfectly competitive markets. They derive illuminating results about trade patterns and gains from trade, among other things, leaving unanswered the question of existence of equilibrium, however. The central significance of their characterization of properties of free trade equilibria with inter-industry and intra-industry trade calls for an analysis of existence of equilibrium. This is the object of the present paper. We prove the existence of equilibrium for the integrated multi-sector multi-factor Helpman–Krugman economy without national borders. Well-known conditions ensure that the world economy under free trade reproduces this equilibrium and thus establishes existence of a free trade equilibrium. Since an equilibrium of the integrated economy is not necessarily unique, the same holds true for a free trade equilibrium. 相似文献

Besides the more commonly used REITs, German investors can also invest in a lesser-known real estate vehicle, Open-ended Property Funds. OPFs are considered a compromise between listed and direct real estate investments. OPF fund managers generally provide daily (perfect) liquidity. However, if liquidity falls below 5%, share redemptions in these funds can be temporarily suspended for a period of up to two years. During this time, investors will only be able to sell shares on the secondary market (exchange), and are thus subject to significant liquidity risk. The objective of this paper is to analyze whether OPFs add value to investor portfolios above that provided by REITs. We show that OPFs have a diversification advantage over REITs in low-risk portfolios, despite their larger potential liquidity risk. REIT liquidity is comparable to that of ordinary common stock, but OPFs exhibit an average initial discount to funds’ NAV of about 6% when share redemptions are temporarily suspended. However, in the long-run, this potential redemption suspension does not negatively influence OPF performance (in case OPFs reopen again). This makes OPFs an attractive investment alternative to REITs for investors who have a high level of risk aversion and a long-term investment horizon, such as endowments, insurance companies, and pension funds. 相似文献

Importance of spatial proximity between venture capital investors and investees in Germany 总被引:1,自引:0,他引:1
Based on 1182 dyads of venture capitalists and German portfolio companies involved in a financing round between 2002 and 2007, the study here examines the importance of spatial proximity between investors and investees in a dense economy. Analysis of this data shows that the probability of a financing relationship decreases by 8% if the journey time increases by one standard deviation. For deals involving very small or very large investment sums, and for less experienced venture capitalists and lead investors, spatial proximity is particularly important. The results suggest that even in economies with a dense infrastructure such as Germany spatial proximity between investor and investee impacts the likelihood of an investment. 相似文献

Narrative is increasingly being recognised as an important tool both to manage and understand organisations. In particular,
narrative is recognised to have an important influence on the perception of environmental issues in business, a particularly
contested area of modern management. Management literature is, however, only beginning to develop a framework for evaluating
the quality and legitimacy of narratives. Due to the highly fluid nature of narratives, the traditional notion of truth as
reflecting ‹objective reality’ is not useful here. In this article, an alternative approach that evaluates a narrative in
two stages is developed. First, a horizontal reading investigates the surface of the narrative, its textual features, instrumental
devices and its integrity as a text, to assess the quality of a narrative. Second, a more philosophical or vertical reading
makes explicit the underlying value assumptions that author and reader bring to the writing and reading of the narrative to
assess the narrative’s claim to legitimacy. The framework is then tested against a narrative on the relationship between business
and environment as espoused by a supply chain manager of a UK-based manufacturing company. 相似文献

Corporate social responsibility (CSR) has become an increasingly significant managerial concept, yet the manager as an agent
of corporate bureaucracy has been substantially missing from both the analytical and conceptual literature dealing with CSR.
This article, which is both interpretative in nature and specific in reference to the U.K. cultural context, represents an
attempt at addressing this lacuna by utilising qualitative data to explore the perceptions of managers working in corporations
with developed CSR programmes. Exploring managerial perceptions of motives for CSR initiatives, methods of stakeholder engagement,
organisational integration of CSR and its impact on managerial work, this study concludes that an instrumental approach dominates,
which indicates an external–internal organisational paradox in the design and execution of CSR initiatives. 相似文献

Sensitive Survey Questions: Measuring Attitudes Regarding Female Genital Cutting Through a List Experiment 下载免费PDF全文
Potential bias in survey responses is higher if sensitive outcomes are measured. This study analyses attitudes towards female genital cutting (FGC) in Ethiopia. A list experiment is designed to elicit truthful answers about FGC support and compares these outcomes with the answers given to a direct question. Our results confirm that the average bias is substantial as answers to direct questions underestimate the FGC support by about 10 percentage points. Moreover, our results provide suggestive but not statistically significant evidence that this bias is more pronounced among uneducated women and women targeted by an NGO intervention (not randomly assigned). 相似文献

In this study, we explore the historical roots of the relatively new topic in scientometrics of academic efficiency assessments. We are interested in the contributions of researchers from the past which have been revealed as important for the topic in the long run. The technique of Reference Publication Year Spectroscopy (RPYS) has been recently introduced which is based on the analysis of the frequency with which references are cited in the publications of a specific research field (here: academic efficiency assessments). The study is based on papers conducted for a systematic review of empirical articles on technical efficiency in academic research production: 60 papers (published between 1992 and 2012) and 1314 cited references. Results indicated that 5 peaks are clearly identifiable until 2000. They correspond, respectively, to the years 1957 (The founding article of Farrell), 1978 (Proposition of a new promising approach: the Data Envelopment Analysis (DEA) by Charnes et al.), 1988 (Research-teaching multi-output model and integration of quality indicators), 1990 (DEA in the service of Research Assessment Exercise) and 1997 (Introduction of weight restrictions in DEA). The peaks are described with the underlying publications and recent developments (since 2000) in the area of academic efficiency studies are outlined. 相似文献

We construct a meta-ranking of 277 economics journals based on 22 different rankings. The ranking incorporates bibliometric indicators from four different databases (Web of Science, Scopus, Google Scholar, and RePEc). We account for the different scaling of the bibliometric indicators by standardizing each ranking score. We run a principal component analysis to assign weights to each ranking. In our meta-ranking, the top five journals are given by: Quarterly Journal of Economics, Journal of Financial Economics, Journal of Economic Literature (JEL), Journal of Finance, and Econometrica. Additionally, leaving out the JEL as a survey journal and the finance journals in our top 10 list we confirm the perceived top five journals in the economics profession. 相似文献
