Competitive trade models and real world features

Competitive small-dimension international trade models perform well in comparing free (or restrictive) trade with autarky, especially in emphasizing that consumption patterns can differ from production patterns and that production becomes highly concentrated while consumption patterns are expanded. Variations on these small-dimensional models can usefully show how with trade production patterns may nonetheless be more diverse and a country’s labor force become more heterogeneous in its skills. The paper illustrates how the Middle Products framework can be reinterpreted to support variety in production and in labor skills.      

A structural portfolio balance model of the Sterling-Dollar exchange rate

Zusammenfassung Ein Strukturmodell des verm?genstheoretischen Ansatzes zur Erkl?rung des Pfund-Dollar-Wechselkurses. — In diesem Aufsatz wird eine Variante des verm?genstheoretischen Ansatzes zur Bestimmung des Wechselkurses in seiner Strukturform auf den Pfund-Dollar-Kurs des Zeitraums 1973–1982 angewandt. Dabei wird die Methodologie von Brainard und Tobin benutzt, wodurch sichergestellt wird, da\ die Koeffizienten bestimmten Restriktionen genügen. Gesch?tzt wird das Modell sowohl mit der Kleinst-Quadrate-Methode als auch mit dem Theil-Goldberger-Verfahren der gemischten Sch?tzungen. Mehrere Aktiva-Schocks werden simuliert und die Reaktionen der Zinss?tze und der Wechselkurse aufgezeigt.

Résumé Un modèle structurel de ?portfolio balance? du taux de change Sterling-Dollar.- Dans cet article les auteurs appliquent la structure d’une version de l’approche de ?portfolio balance? à la détermination du taux de change sterling-dollar sur la période 1973–1982. Dans le modèle, la méthodologie de Brainard et Tobin est utilisée qui garantit que les restrictions nécessaires d’addition sont satisfaites. Les méthodes des moindres carrés ordinaires aussi bien que les procédures d’estimation mixte de Theil-Goldberger sont appliquées pour estimer le modèle. Les auteurs simulent un nombre des chocs d’actif et illustrent la réponse des taux d’intérêt et du taux de change.

Resumen Un modelo ?portfolio balance? estructural del tipo de cambio entre la libra esterlina y el dólar. - En este trabajo se presenta una versión del modelo de ?portfolio balance? para determinar el tipo de cambio, que es implementado estructuralmente para el tipo libra esterlina - dólar en el período 1973–1982. En la implementación de este modelo se utiliza la metodología de Brainard y Tobin, que garantiza la consistencia de las restricciones. Con el fin de estimar el modelo se aplica tanto el método de cuadrados mínimos como también el método mixto de Theil y Goldberger. Se llevan a cabo varias simulaciones a base de shocks de activos para ilustrar la reacción de las tasas de interés y del tipo de cambio.

     

Ethnicity,acculturation, and the importance of product attributes

This investigation examined the relationship between subcultural group membership and the importance of various product attributes in purchase decisions. Subcultural group membership was defined on the basis of Hispanic ethnicity and level of assessed acculturation. The results indicate that cost considerations such as price and the availability of credit best distinguish these groups. This is particularly meaningful, given that these results persist even when income level is statistically controlled. The second major purpose of the investigation was to test the appropriateness of the traditional progressive learning model of acculturation within the specific buyer behavioral context of product attribute importance. The findings clearly indicate support for this model.     

Politico-economic inequality and the comovement of government purchases

This paper explores the implications of economic and political inequality for the comovement of government purchases with macroeconomic fluctuations. We set up and compute a heterogeneous-agent neoclassical growth model, where households value government purchases which are financed by income taxes. A key feature of the model is a wealth bias in the political aggregation process. When calibrated to U.S. wealth inequality and exposed to aggregate productivity shocks, such a model is able to generate weaker positive comovement of government purchases than models with no political wealth bias. The wealth bias that matches the cross-sectional campaign contribution distribution by income is consistent with the mild positive comovement of government purchases in the aggregate data. We thus provide an empirically relevant example where economic and political heterogeneity matter for aggregate dynamics.     

Asset Market and Balance of Payments Characteristics: An Eclectic Exchange Rate Model for the Dollar,Mark and Yen

In this paper we use an exchange rate model, which combines asset market characteristics with balance of payments interactions, to examine the nominal effective exchange rates of the German mark, Japanese yen and US dollar for the recent experience with floating exchange rates. Our approach may be interpreted as one which attempts to flesh out the missing links that arise in conditioning an exchange rate solely on relative prices, as occurs in a standard PPP analysis. Amongst the results reported in this paper are: significant, and sensible, long-run relationships for the currencies studied; complex short-run dynamics; a variance decomposition analysis which apportions nominal exchange rate error variances into real and nominal elements.     

Motivators of market mavenism in the retail environment

This study examines relationships between market mavenism and five other consumer characteristics. We conceptualize three of these characteristics as broad marketplace concepts at the same (or higher) level of abstraction as mavenism. The remaining two variables are involvement with specific product categories: mobile phones and clothing. The data come from a survey of 258 US student consumers. The results show that mavenism is positively associated with brand engagement in self-concept, status consumption, and materialism. Mavenism is also positively associated with involvement with mobile phones and with clothing. This pattern of relationships enriches the nomological network of market mavenism by describing possible motivators and consequences of this unique aspect of consumer behaviour.     

Optimal transaction filters under transitory trading opportunities: Theory and empirical illustration

If transitory profitable trading opportunities exist, transaction filters mitigate trading costs. We use a dynamic programming framework to design an optimal filter that maximizes after-cost expected returns. The filter size depends crucially on the degree of persistence of trading opportunities, transaction cost, and standard deviation of shocks. For daily dollar–yen exchange trading, the optimal filter can be economically significantly different from a naïve filter equal to the transaction cost. The candidate trading strategies generate positive returns that disappear after transaction costs. However, when the optimal filter is used, returns after costs remain positive and higher than for naïve filters.     

International Variation in Bank Accounting Information Content

This study explores the cross‐country impact of financial system and banking regulations on the information content of bank earnings and book value. Test results provide empirical evidence that financial system and banking regulations have a joint effect on the association of equity price with earnings and book value components in Germany, France, the United Kingdom and United States. This effect is explainable by the objective bank function, which shows that earnings of the period determine the terminal book value, thus consistent with the clean surplus accounting approach. Cross‐country variation in bank accounting information content calls for caution in interpreting international bank financial and operating ratios.     

Federal health care policy and the public-general hospital

Conclusion Although a stringent policy environment adversely affects both private and public hospitals, the market circumstances are worse for public hospitals. Because they are providers of last resort, they do not have as much flexibility as private hospitals in determining the quantity and scope of services they provide.
