This article has two goals. The first is to extend previous results regarding calibration of land‐constrained programming models of agricultural supply against supply elasticities to the general case of multiple constraints. The second goal is to demonstrate how the resulting calibration conditions can be used as a source of identification to disaggregate crop supply elasticities down to the level at which static information on acreage allocations is available. We propose an information‐based disaggregation algorithm to systematically generate regionalised elasticities from a single prior, and provide an empirical illustration.  相似文献

The main objective of this work is to understand the extent to which a relationship exists between static patterns and the dynamic configurations of a firm's export behaviour. The premise of our investigation is that the set of exporting decisions adopted over a period of time can be explained, in part, by the export pattern of the firm at the start of that period. Our empirical work is based on a sample of 754 exporting firms covering a 4-year period (2002–2006). Data were obtained from the Survey of Business Strategies (SBS). Our results support the path dependent focus of internationalisation, find some interdependences among three dimensions of export behaviour (extent, entry mode and scope), in static and dynamic fields, and support the idea that export experience influences some of the changes in foreign behaviour at one point in time, but not all. Our work contributes to the literature as it is one of the first works that (1) simultaneously analyses static and dynamic variables; (2) establishing relationships between both variables; (3) different dimensions of international export behaviour are introduced jointly; and (4) these relationships are contextualised according to the firm's export experience.  相似文献

RÉSUMÉ 1 : Le faible niveau moyen d’efficience des institutions bancaires habituellement trouvé dans les études empiriques a été qualifié de « boîte noire » par Berger et Mester (1997) . Cette étude cherche à identifier si les caractéristiques de l’environnement de même que celles qui sont propres à une coopérative d’épargne et de crédit pourraient expliquer une partie des écarts de performance apparaissant dans les scores d’efficience. Le modèle de coût que nous avons estimé est basé sur la valeur ajoutée par l’intermédiation financière. Par ailleurs, pour éviter la perte d’informations découlant de la borne à l’unité des scores d’efficience découlant du DEA, nous avons comparé les résultats d’une analyse avec le score d’efficience et de superefficience. Nos résultats montrent qu’au moins 34% des écarts de scores peuvent être expliqués par un ensemble limité de variables: taille de la coopérative, taux de capitalisation, épargne par membre, nombre de membres et type de marché.  相似文献

The paper proposes in a regime-shift framework, an arbitrage-free term structure model based on the target and Fed Funds Rates. Empirical observations suggest that a three-state regime-shift environment associated with FOMC monetary actions is justified. Then, a closed-form solution for zero-coupon bonds is derived where regime-shift risk is priced. The solution is flexible enough to incorporate additional state variables.  相似文献

Regression-based testing techniques have long been used to quantify whether the efficient frontier of a set of assets spans the frontier of a larger collection of investments. This paper derives regression-based spanning tests for the case in which the investment possibilities set contains, or is constituted by, futures contracts for which marked-to-market margins are explicitly taken into account. Two empirical applications illustrate our results.  相似文献

This study provides insight into the impact of industrial districts on the international activities of firms, in the particular context of one traditional manufacturing industry: the Spanish home-textile industry. Using a sample of 128 manufacturing firms, the paper shows how location influences the timing and levels of exports and imports. Moreover, our results demonstrate how these influences have been diluted in recent years as the home-textile industry becomes more involved in the global arena. Our findings challenge some key arguments exploring the advantages of the district in the international activities of firms; in particular, first, in questioning the capacity of the district to prevent international sourcing, and second, its vulnerability to the threats created by the growing integration of the world economy.  相似文献

The main purpose of this survey is to present the results of a questionnaire recently sent to historians of economic thought. This questionnaire — presented in the appendix - was devised so as to provide data on the approaches and experiences of teaching the history of economic thought in a wide range of universities throughout the world.

A summary of the most significant results is presented in section 2 of this survey. Section 1 provides a general introduction to the methodological context of the discussion of problems concerning the teaching of the discipline.  相似文献

As in most other industrialized countries the oil price shocks in the seventies led to major rearrangements in the production processes in Dutch manufacturing. The substitution of (expensive) energy consuming processes by less energy intensive ones is analyzed by means of a dynamic equation, relating the energy demand to the level of output, the price of energy and the prices of other inputs. Using a rather unique data set, consisting of panel data pertaining to several thousands of manufacturing firms, it is found that large firms can reduce energy costs more than small firms.This article reports on research carried out in the MOPS-project. Participants of MOPS are the Netherlands Central Bureau of Statistics, the Research Institute for Small and Medium-sized Business in the Netherlands, and the Erasmus University Rotterdam. The views expressed in this article do not necessarily reflect the policies of the Netherlands Central Bureau of Statistics.The authors thank Bert Balk, Jos van Deventer, Peter Kooiman, Huib van de Stadt, Roy Thurik, Wim Vosselman, Ton Werkhoven and two anonymous referees for helpful comments.  相似文献

This paper investigates how various conjoint designs (full versus fractional) and estimation procedures (LINMAP, MONANOVA, OLS) may interact with basic characteristics of the “true” utility functions (i.e., their range, shape, and curvature) when estimating attribute importance weights. Substantial weight distortions are found, especially under a fractional design.  相似文献
