This paper investigates the relative importance of scheduled U.S. macroeconomic news releases for stock valuation. The study
focuses on 11 macroeconomic announcements selected on the basis of the previous literature and the Bureau of Labor Statistics
classifications of major economic indicators. The paper shows that five out of the 11 announcements have significant influence
on stock valuation. These are the Employment Report, NAPM (manufacturing), Producer Price Index, Import and Export Price Indices,
and Employment Cost Index. Of these six announcements, the Employment Report and NAPM (manufacturing) exert the greatest influence.
The time of the announcement, measured by days from the beginning of the month to the release day, has a moderating impact
on the relationship between macroeconomic announcements and its importance. 相似文献

This paper explores the sensitivity of the size distribution of family income in Canada to alternative definitions of income. These alternative definitions examine both wealth generally in the form of an annuity equivalent, and home ownership in the form of imputed rent. An adjustment for family size differences is also made. The impact of these adjustments is assessed for average incomes, inequality, and the incidence of low income for different age groups. The adjustments do have significant effects that vary by age; in particular, the economic position of the elderly seems understated by the usual data. Also, methodological considerations, such as the direct use of micro data and the choice of inequality indicator are shown to be significant. 相似文献

Synopsis This paper is the product of a collaboration between a biologist (Ghiselin 1997) who works on the philosophy of classification
and an economist (Landa 1981, 1994) who works on the ‘Economics of Identity’: how and why people classify people based on
identity in the context of a theory of ethnic trading networks. In developing the ‘bioeconomics’ (the synthesis of economics
with biology) of classification, we crossed a number of disciplinary boundaries—anthropology, economics, sociology, biology,
and cognitive psychology including evolutionary psychology’s ‘fast and frugal’ heuristics. Using a bioeconomics approach,
we argue that folk classifications—the classifications used by ordinary persons—have much in common with scientific classifications:
underlying both is the need for economy of information processing in the brain, for the efficient organization of knowledge,
and for efficiency of information acquisition and transmission of information to others. Both evolve as a result of trial
and error, but in science there is relatively more foresight, understanding, and planning. 相似文献

Summary In this paper we consider a class of time discrete intertemporal optimization models in one dimension. We present a technique to construct intertemporal optimization models with nonconcave objective functions, such that the optimal policy function coincides with any pre-specifiedC
2 function. Our result is a variant of the approach presented in a seminal paper by Boldrin and Montrucchio (1986). Whereas they solved the inverse problem for the reduced form models, we address the different question of how to construct both reduced and primitive form models. Using our technique one can guarantee required qualitative properties not only in reduced, but also in primitive form. The fact that our constructed model has a single valued and continuous optimal policy is very important as, in general, nonconcave problems yield set valued optimal policy correspondences which are typically hard to analyze. To illustrate our constructive approach we apply it to a simple nonconcave model.We are grateful for the helpful comments of L. Montrucchio, K. Nishimura, T. Mitra and an anonymous referee.

We develop a model of marketing efficiency based on a directional distance function that allows for marketing spillovers. A parametric model is used to test for spillovers from rival marketing and from a firm's marketing activity of its other related products. We then show how this information can be incorporated into a non‐parametric model and used to estimate marketing inefficiency. We apply brand level data from the US brewing industry to the non‐parametric model to determine the effectiveness of television, radio, and print advertising. We find that advertising spillovers are important in brewing and show that efficiency estimates are inaccurate when spillover effects are ignored. Our results also suggest that marketing efficiency may be an important component to firm success in brewing, a result that may apply to other consumer goods industries.
