Résumé: Au Togo, la production alimentaire est en baisse continue et l’état de l’environnement est marqué entre autres par la dégradation des ressources naturelles. La présente étude vise àévaluer la contribution des facteurs environnementaux à la croissance alimentaire. L’hypothèse fondamentale est que la croissance alimentaire au Togo est moins liée aux aléas climatiques qu’aux investissements en capital physique et humain. L’étude aboutit à la conclusion que la variable environnementale n’est pas déterminante dans l’explication de la variation de la production alimentaire ce qui confirme notre hypothèse initiale. En conséquence, les politiques de production alimentaire futures au Togo ne doivent pas privilégier les variables du capital physique au détriement de la variable environnementale. Il convient donc de rechercher à l’avenir la combinaison optimale des facteurs du capital physique et du capital humain et de l’environnement qui garantisse de manière durable la production alimentaire dans le cadre de la formulation de la politique de sécurité alimentaire au Togo. 相似文献

This paper shows that, in the 2 × 3 sector‐specific capital Harris–Todaro model, capital growth owing to either domestic or foreign investment always enhances the welfare of the country (i.e. non‐immiserizing), and this result of non‐immiserizing foreign investment holds regardless of initial holdings of foreign capital; the policy of industrial targeting via capital investment is more effective vis‐à‐vis the (neoclassical) 2 × 2 mobile‐capital Harris–Todaro model or the Heckscher–Ohlin model; in contrast to the recent generalization by Marjit and Beladi (2003 ), capital growth cannot be immiserizing in the present model, even if it destroys the “envelope theorem.” 相似文献

Modeling Cyclical Asymmetries in GDP: International Evidence 总被引:1,自引:0,他引:1
This paper models asymmetric behavior in GDP growth in the USA, Germany, France, and Japan. It develops smooth transition autoregressive models and interprets nonlinear dynamics in terms of cyclical asymmetries. A procedure for defining data-based, qualitative cyclical regimes from the estimated models is proposed, and generalized impulse response functions are computed to assess to what extent the response to a shock changes over different phases of the cycle. 相似文献

Creditor Rights, Enforcement, and Bank Loans 总被引:1,自引:0,他引:1
We examine whether differences in legal protection affect the size, maturity, and interest rate spread on loans to borrowers in 48 countries. Results show that banks respond to poor enforceability of contracts by reducing loan amounts, shortening loan maturities, and increasing loan spreads. These effects are both statistically significant and economically large. While stronger creditor rights reduce spreads, they do not seem to matter for loan size and maturity. Overall, we show that variation in enforceability of contracts matters a great deal more to how loans are structured and how they are priced. 相似文献

This study examines the effect of multiknowledge individuals (especially those possessing both marketing and technological knowledge) on performance in cross‐functional new product development teams. A survey of 62 cross‐functional teams shows that the proportion of multiknowledge individuals has an indirect positive effect through information sharing on product innovativeness and a direct positive effect on time efficiency of new product development teams. 相似文献

This paper deals with the collective qualification of members of society as belonging to a certain category or group based
on a fixed attribute. Our model contains three main features: the existence of individual gradual opinions, the notion of
elitism (only the opinions of certain individuals are taken into account to delineate the reference group), and the idea of sequentiality (elites are successively created by using the previous elites’ opinions on a social decision scheme). The main results of
the paper characterize when this sequential procedure converges for some intuitive ways of aggregating individual opinions.
Finally, we analyze the role of convergence for two extra basic properties (symmetry and contractiveness) that elitist rules
should possess. 相似文献

This study draws on the Resource‐Based View to analyze the effects of distinctive competences in tourism firms and location in a tourism district on competitive position, and explores the moderating effects of the tourism destination. Multiple linear regression was used to test the research hypotheses on a sample of 1019 Spanish tourism firms. Results reveal that financial resources and dynamic and production capabilities favor a better competitive position for tourism firms in general; however, coordination and marketing capabilities are key factors for firms embedded in a tourism district, while dynamic capabilities have a negative effect in this case.

The extent to which tourism destination marketing narratives with different themes influence readers by imaginatively ‘transporting’ them is quite varied. This study investigates the different degrees of influence such narratives have on destination image and the intention to visit, exploring how the intensity of readers' experiences of being transported by narratives with different themes can influence their intention to visit the places described. Our results reveal the extent to which different narrative themes affect destination image and significantly influence readers' intention to visit. The extent to which narratives with different themes make readers feel transported also has a significant moderating effect on their intention to visit. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

We explore determinants of flood insurance demand in the coastal zone using micro‐data for nine Southeastern counties. Overall estimates indicate price inelastic demand, though subsidized policyholders have greater coverage and are more price sensitive. Mortgage borrowers exhibit no greater coverage; only 12 percent in 100‐year flood zone indicate flood insurance was required by their lender. Flood insurance demand is increasing in the levels of flood and erosion risk. We find a positive correlation between household income and coverage, but the effect is not monotonic. Community‐level erosion hazard mitigation projects influence flood insurance coverage, with beach replenishment acting as a complement. 相似文献

We present a portfolio decision model for banks that permits us to estimate the costs associated with the need to collateralise loans from the central bank. This allows us to calibrate the difference between a restrictive collateral eligibility framework for open market operations, such as that applied by the FED, with a more flexible approach such as that of Eurosystem. We also document that there could potentially appear relevant cost differences between the various collateral mobilisation procedures (pooling and earmarking) that currently coexist in the eurozone. 相似文献
