Do Investment Newsletters Move Markets?

We analyze the market impact of stock recommendations made by a single investment newsletter that focuses on instances of heavy insider trading. The market reacts positively to the actual insider trades and the associated Form 4 Securities and Exchange Commission (SEC) filings that attracted the newsletter's interest. The subsequent recommendations, which occur within a delay of several days, are associated with an even larger announcement period return and higher trade volume. Thus, despite the fact that recommendations are largely based on publicly available information on insider trades and the reach of the newsletter is limited, the newsletter has a significant impact on the market.     

Fourier-analytic measures for heavy-tailed insurance losses

We propose a family of three ‘Fourier-analytic’ measures to extend the conventional concepts of standard deviation, variance, and coefficient of variation to insurance losses with arbitrarily heavy tails. After motivating and computing their mathematical forms, we apply the proposed measures to the case of Lévy-stable loss portfolios. Finally, the new measures are used to study the diversification properties of heavy-tailed losses.     

Adaptation of Marketing Mix Elements in International Markets

ABSTRACT

This research identifies the extent to which individual marketing mix elements are adapted for international markets and how company, industry, and market factors influence the level of adaptation. The study is based on a survey of executive-level managers in U.S.-based companies that market products internationally. The survey obtained information on the extent of adaptation across the marketing mix elements and on company, industry, and market factors that influence this process. The results indicate that adaptation is greatest for distribution, followed by price, promotion, and product. Product adaptation is influenced by market factors, price adaptation is influenced by market and industry factors, promotion adaptation is influenced by market factors, and distribution adaptation is influenced by company factors. The results of the research can be used to both understand and manage the extent of adaptation necessary for products in international markets.     

Improving health outcomes through patient empowerment

The concept of empowerment can be successfully used in the healthcare industry to positively influence patient participation and compliance with their program of treatment. This paper examines the literature that has developed in the area and presents a model that incorporates patient empowerment into the healthcare delivery process. Managerial implications and directions for future research are also presented.     

Motives for foreign direct investment in the United States

As foreign direct investment becomes an important element of the global marketplace it is important to understand why firms use FDI as an investment option. This article reports research that identifies motivations that influence factor‐ and market‐seeking inward FDI in the United States. Based on a study of 127 foreign companies investing in the United States, the research identifies motivators that differentiate and explain these two types of investment behaviors. © 2003 Wiley Periodicals, Inc.     

The Size and Frequency of Price Changes: Evidence from Grocery Stores

We analyze a data set (on grocerystore prices for lettuce) with many advantages overthose used previously to explain firm heterogeneity inthe size and frequency of price changes. Despitecommon shocks to their input price, grocers' pricechanges vary widely in size and frequency. We testhypotheses emerging from a theoretical framework. Wefind that product, firm, and market characteristicsassociated with the benefits from and costs ofchanging price explain grocer-to-grocer variation inthe size and frequency of price changes. Moreconcentrated markets, larger firm size, and thinnerproduct markets lead to infrequent and large pricechanges.     

Food Deserts and Real‐Estate‐Led Social Policy

Since the early 2000s in the United States, food deserts—neighborhoods in which households have limited geographic access to full‐service supermarkets or grocery stores— have become conceptually central in public policy research on food security. Analyzing this phenomenon from a ‘policy mobility’ perspective, this article traces the food desert's emergence in policy discourse, locating it within an entrepreneurial social policy paradigm that privileges real estate development over direct economic relief. In the context of property‐led anti‐poverty efforts, the identification and mapping of food deserts catalyzes a logic that leads to subsidy to grocery store development in low‐income areas (or ‘fresh food financing’), while at the same time officials are cutting programs such as the Supplemental Nutrition Assistance Program (food stamps), which directly supplements household food budgets. The article contributes to widening critical discussion of the food desert paradigm and the policy interventions with which it is associated. It calls on urban researchers and practitioners to reframe discussions of food access and nutrition around the shortage of basic income and a need for higher wage floors.
