Cultural metaphors and KMS appropriation: Drawing on Astérix to understand non-use in a large French company

Management research is increasingly using fiction as an insightful way to analyze complex organizational dynamics. Focusing on user appropriation of Knowledge Management Systems, we describe how we used the popular Astérix, a well-known French cartoon to better understand KMS appropriation. We came to use this approach in an action research project in a large French construction firm initially designed to help Chief Knowledge Officers address KMS non-use. After our first findings showed paradoxical cultural issues, and based on the idea that culture is central to sensemaking and appropriation, we used the notion of the cultural metaphor to help better understand the cultural aspects associated with KMS appropriation. These results contribute knowledge in three different areas. First, we underline the role of cultural metaphors in information systems appropriation. Second, we enrich the literature on the role of fiction in management by illustrating the role of cultural metaphors. Third, we report on how this can be used in an action research project to help better understand KMS appropriation issues, which has the potential of leading to practical managerial action.     

Is late really better than never? The farmer welfare effects of pineapple adoption in Ghana

Export agriculture offers potentially high returns to smallholder farmers in developing countries, but also carries substantial market risk. In this article we examine the intertemporal welfare impact of the timing of a farmer's entry into the export pineapple market in southern Ghana. We examine whether farmers who never cultivated pineapple are better or worse off than farmers who decided to adopt pineapple earlier or later relative to their peers and experienced a significant adverse market shock several years prior to our endline survey. We use a two‐stage least squares model to estimate the causal effect of duration of pineapple farming on farmer welfare. Consistent with economic theory, we find that earlier adoption of the new crop brings greater welfare gains than does later uptake. But we find that the gains to later uptake of pineapple—just before the market shock—are small in magnitude, just 0.1 standard deviations of a comprehensive asset index, indicating that the gains to adoption may be precarious and depend on the context, in particular on the severity of prospective market shocks.

Household Satellite Account for France

We estimate in a household satellite account (HHSA) the value of French domestic production in 2010 and 1998, using the input method and following Eurostat's recommendations. In line with previous studies, we find that extending the system of national accounts (SNA) frontier of production to domestic activities (house chores, cooking, care …) has a sizeable effect on key macroeconomic indicators (+33 percent GDP, ?5 p.p. GDP growth, +50 percent disposable income, +58 percent consumption, and ?10 p.p. of purchasing power growth). We conduct a sensitivity analysis to various methodological issues which have not yet been settled by an international benchmark. Quantitatively, the two most important issues are the boundary of household production—we favor a relatively narrow definition—and the use of a gross or a net wage—we prefer gross wage‐. However, estimates are much less sensitive to otherwise greatly debated issues such as which substitute wage to use.     

Convergence and performance of the peeling wavelet denoising algorithm

This note is devoted to an analysis of the so-called peeling algorithm in wavelet denoising. Assuming that the wavelet coefficients of the useful signal are modeled by generalized Gaussian random variables and its noisy part by independent Gaussian variables, we compute a critical thresholding constant for the algorithm, which depends on the shape parameter of the generalized Gaussian distribution. We also quantify the optimal number of steps which have to be performed, and analyze the convergence of the algorithm. Several implementations are tested against classical wavelet denoising procedures on benchmark and simulated biological signals.     

Comparing Customer and Supplier Perceptions of Value Offerings: An Exploratory Assessment

This paper proposes an exploratory assessment of similarities and differences between the perceptions of suppliers and their customers about what is important in a value offering—and to which extent—in a specific business sector.     

Sequential location under one-sided demand uncertainty

In entering a new market, firms face demand uncertainty. We depart from the usual Hotelling duopoly model with sequential entry. We allow firms to locate outside of the city and assume that market conditions are common knowledge. We then introduce one-sided demand uncertainty. We find that demand uncertainty can be seen as a differentiation force when faced by the first entrant and as an agglomeration force when faced by the second entrant. Finally, the second firm’s imperfect information implies higher welfare losses.     

Sharing Money Creation in a Monetary Union*

How to share money creation among the members of the European Monetary Union? To address this issue, we construct a two‐country New Open‐economy Macroeconomics model of an asymmetric monetary union with an incomplete financial market and home bias in consumption. We consider two sharing rules consistent with the current regulations of the European System of Central Banks. First, each participating National Central Bank supplies half of the European Central Bank determined money creation in the monetary union. Secondly, each National Central Bank adapts the national increase in money demand, under the constraint that the total money creation in the union does not exceed the level determined by the ECB for the whole union. We show that the current sharing rule, which ignores countries’ heterogeneity, is superior in terms of welfare. The key role of the current account is emphasized. It proves an efficient decentralized mechanism for allocation of money.
