Financial acumen, women speculators, and the Royal African company during the South Sea bubble

Price bubbles provide a unique opportunity to study the financial acumen of shareholders. We focus on the 1720 South Sea episode as experienced by the Royal African Company whose stock was more speculative than other joint stocks. During 1720 the company had a new large stock issue. This paper examines the financial acumen of those women who traded senior and engrafted stock across 1720. We find that depending on the pricing regime, these women at worst broke even on their activities or had positive speculative gains. Our findings are consistent with a growing literature on the positive link between gender, capital gains and financial markets.     

Determinants of restaurant's owners/managers selection of wines to be offered on the wine list

The aim of the paper is to better understand wine list design in restaurants in four countries with very different wine cultures. An interview protocol was developed and administered to 286 restaurants across the four countries (France, Australia, USA and China). The interview questionnaire included a Best/Worst methodology to identify the most/least important factors influencing the restaurant's owner/manager's selection of wine for the wine list. One of the most important reasons for selecting wine across most countries is ‘to match wine with the food menu’. There were few major differences between countries, but a latent class analysis found four clusters that differed significantly with membership also differing between countries. The cluster analysis also indicated that while some restaurateurs are more brand-driven, others value local wine or its matching with the food menu.     

The cost of quality in existing housing: Estimates from an implicit markets model

Rosen's implicit markets approach is used to model and estimate the cost of improving the state of repair of rental housing in existing structures. Particular attention is devoted to potential errors in the measurement of state of repair and to the inconsistent estimates of supply and demand parameters implied by Rosen's original econometric technique. Cost estimates imply that improvements in low-income housing could be provided much less expensively in existing housing than by either public new construction or the Section 8 existing housing program.     

Regional Economic Impacts of Fusarium Head Blight in Wheat and Barley

Fusarium Head Blight is a fungus affecting wheat and barley in the upper Midwest region of the United States. The purpose of this study is to estimate the direct and secondary regional economic impacts of Fusarium Head Blight infestations from 1998 to 2000. Cumulative direct production and price impacts from Fusarium Head Blight in hard red spring, soft red winter, durum wheat, and barley are estimated at $871 million over the period, with secondary economic losses of $1.8 billion. The total impacts of $2.7 billion were concentrated in North Dakota and Minnesota, which accounted for 55% of total losses over the period.     

QUADRATIC SINGLE AND MULTI-COMMODITY MODELS OF SPATIAL EQUILIBRIUM: A SIMPLIFIED EXPOSITION

This paper presents a somewhat simplified exposition of quadratic single and multi-commodity models of spatial equilibrium. The intent is to facilitate their understanding by students and researchers. A graphical model is presented which illustrates the necessary conditions for spatial equilibrium. Then single commodity programming models with, first, quantities and, subsequently, prices in the decision domain are constructed. The equivalence of the graphical and programming models, as well as application of the necessary conditions as constraints in the programming models, are ilustrated. Finally, a multi-commodity model with asymetric demand and supply coefficients is constructed as a primal-dual formation in which the constraints are the necessary conditions for spatial equilibrium.
Cet exposé présnte une interprétation assez simplifiée de modéles quadratiques d'équilibre spatial à produits individuels et multiples. Son dessein est de faciliter aux étudiants et aux rechercheurs leur compréhension de ces modèles. Un modèle graphique qui montre les conditions nécessaires à I'équilibre spatial est présenté. Ensuite, des modèles de programmation à produits individuels sont construits avec, premièrement, des quantités dans le domaine de la prise des décisions et, par la suite, avec des prix dans ce mème domaine. L'équivalence des modèles graphiques et des modèles de programmation, aussi bien que l'application des conditions nécessaires comme contraintes dans les modèles de programmation, y sont illustrés. Enfin, un modél à produits multiples, avec coefficient asymétriques de demande et d'offre, est construit comme formulation unique/double dans laquelle les contraintes sont les conditions nécessaires à l'équilibre spatial.     

Entry,reputation and intellectual property rights enforcement

We examine how reputation concerns induce a multinational to partly withhold its entry into a developing country under weak intellectual property rights (IPR) enforcement. Equilibrium IPR violations are shown to arise only in the presence of such concerns. Holding constant a multinational's incentive to innovate, better IPR enforcement encourages entry but reduces social welfare. The multinational's incentive to innovate may be inversely U‐shaped in the strength of IPR enforcement. If timed properly, however, stronger IPR enforcement can foster innovation without compromising social welfare. Testable implications concerning observable IPR violations are derived.
