Perceptions of Urban Parks as Havens and Contested Terrains by Mexican-Americans in Chicago Neighborhoods

The objectives of this study were to (1) identify the benefits of parks for Mexican-American urban residents and the roles they play in the dynamics of their communities and (2) explore issues related to their existence and utilization in Latino communities. Bedimo-Rung, Mowen, and Cohen's (2005) model of the Role of Parks in Public Health was employed as a conceptual framework in this study. Data were collected in the summer of 2007 with two focus groups with 26 Mexican-American residents from two predominantly minority Chicago communities. Benefits of urban parks for Mexican-American residents were classified into five categories—environmental, social, psychological health, physical health, and cultural. The study also identified many problems related to the existence and utilization of parks in Latino communities that detracted from the benefits Mexican-Americans could obtain from visiting parks. They included insufficient access to parks, poor maintenance of the existing parks, crime and safety issues, and interracial conflict and discrimination. A new framework was proposed to model the benefits of parks for minority urban residents and factors that affect utilization of parks in minority communities.     

Smokeless tobacco,smoking cessation and harm reduction: an economic analysis

Good estimates place ‘hard core’ smoking rates in the United States at approximately 25%, with little change over the decade of the 1990s. This paper examines the possibilities of ‘harm reduction’ with the use of smokeless tobacco. Specifically, using an econometric model we seek to determine whether an increase in the use of smokeless tobacco would lead to reduced smoking rates in the United States. Applying our model to the NHANES III (National Health and Nutrition Examination Survey) we find that the use of smokeless tobacco by an average U.S. male smoker would increase the average probability of smoke cessation by over 10%. Approximately 3 million additional ‘quits’ would result for 26 million smokers. Our study permits an examination of cessation by age groups and we find that males who use smokeless tobacco between 16 and 65 have a 10–14% probability of quitting but that the probability falls beyond age 66. Important implications for life extension and health costs would attend these results with, under conservative assumptions, life years saved approximating 2.16 million and health care cost-savings of about $3 billion per year.     

Stock exchange governance initiatives: Evidence from the Italian STARs

Can a stock exchange improve corporate governance and transparency by designating companies that exhibit superior corporate governance? In 2000, the Borsa Italiana created a mid-cap segment with strong listing standards, which is composed of firms (called STARS) that follow stricter standards of transparency, disclosure, monitoring and liquidity. We find that STAR firms exhibit governance characteristics not observed in non-STAR firms, such as a higher incidence of audit and executive committees and higher debt ratios. They experienced a modestly favorable share price response upon the implementation of the STAR initiative. Moreover, they experienced significantly higher buy and hold returns and transparency after the initiative. Several governance characteristics are cross-sectionally associated with performance following the STAR initiative. Overall, the results suggest that firms may be willing to improve governance when they are endorsed by a credible agency for doing so, and such improvements may lead to better performance. The STAR initiative may serve as a model that can be adapted by other stock exchanges to promote transparency and governance.     

Applying an extended theory of planned behavior to examine state-branded food product purchase behavior: The moderating effect of gender

ABSTRACT

The purpose of this study was to use an extended model of the theory of planned behavior to investigate the antecedents which lead to consumers’ purchase of state-branded food products. Relationships among attitude, subjective norm, perceived behavioral control, health-consciousness, intention to purchase, and actual purchase were examined. In addition, the moderating role of gender on consumer purchasing was assessed. The hypothetical model was empirically tested using data collected via Amazon Mechanical Turk (Mturk). Results implicated that consumers’ attitude, subjective norm, and perceived behavioral control of purchasing state-branded products significantly predicted their intention to purchase, and consumers’ intention to purchase significantly predicted their actual purchase of state-branded products. The relationship between health-consciousness and intention to purchase, however, was not found. Gender differences were found only between consumers’ perceived behavioral control of state-branded purchasing and their intention to purchase. Implications for marketers, farmers, and restaurant owners are provided.     

Do Institutional and Individual Investors Differ in Their Preference for Financial Skewness?

Employing a unique sample of individual and institutional investors, we conduct experiments to determine investors’ preference for (or indifference to) financial skewness. We present investors with a series of stocks with varying levels of skewness. Using Instant Response Devices, we then collect investors’ choices to hold or sell each stock. Among stocks with equal expected returns, we find strong evidence that the sample investors use a prospect theory utility function rather than a mean-variance expected utility function to decide to sell or hold stocks. In the loss domain, we find that investors are ambivalent about the choice between positively and negatively skewed stocks. However, in the gain domain, we find that both individual and institutional investors prefer negatively skewed stocks—a contrast from previous research suggesting that individuals (and not institutional investors) prefer positive skewness. We also find evidence suggesting that reference points are important in financial decision making.     

The Role of Economics in Interdisciplinary and Problem-Oriented Programs

Although research on the teaching of economics beyond the introductory course appears to be increasing, it is still rare. This study is one of the few that deals with the intermediate level. Ault and Rutman used a three-part test (one part of which was made up of an essay question) in measuring student knowledge before and after instruction in intermediate theory. They compared an experimental group being taught through a problem-centered format (in combination with the usual lecture-discussion approach) with a control group getting only the lecture-discussion treatment. The experimental students did no better than the control students, but the authors discuss several variables that might help to explain these results.     

Optimal pest control in greenhouse production of ornamental crops

In this study, we develop a conceptual bioeconomic model of floriculture production with aesthetic benefits, wherein optimal decision rules depend on an intertemporal economic objective to maximize profits subject to economic and biological processes. Necessary conditions of the model identify optimal trajectories (e.g., simultaneous, single, or cycling controls) that define decision rules and economic thresholds for profit maximizing growers producing crops with aesthetic attributes. The necessary conditions also highlight intertemporal trade‐offs between aesthetic benefits and expected future net benefits of arthropod stocks, which have important policy implications. The model is applied to the greenhouse production system of ivy geranium.     

Delivering Public Health Care Services: Substitutes,Complements, or Both?

In this article we investigate how the availability of public health care providers increases (complement) or decreases (substitute) the likelihood of having public or private health insurance. The probability of each of three insurance alternatives (uninsured, Medicaid, private insurance) is modeled as a function of the availability of public programs in the respondents'community along with individual characteristics including family income, health status, and family structure. Using population-based estimates, public hospitals are associated with a crowd-out rate of 3.5 percent to 8.6 percent. Federally qualified health centers were associated with a net complementary effect (additional public insurance take-up) of 7.1 percent. (JEL I11 , I18 , I38 )     

Unraveling the Academic Productivity of Economists: The Opportunity Costs of Teaching and Service

This study investigates the relationships among research productivity, teaching, and service on the basis of individual-specific information involving approximately 715 academic economists. Responding to an online survey, these economists provided information regarding their teaching and service commitments as well as personal and institutional information. The publication record of each respondent was then obtained from EconLit. Together, these data constitute a rich field for the systematic study of research productivity. Results of a Tobit analysis reveal much about the nature of research productivity, underscoring, for instance, the importance of gender, coauthorship, presentations at conferences, and peers who publish. Among the more important findings from this analysis is that both teaching and service commitments have a significantly negative impact on the research productivity of academic economists. These relations hold across types of academic employer, though to varying degrees. Taken together, the results provide interesting insights into the roles of academic scholars, teachers, and colleagues.     

Wilderness Canoeing in Ontario: Using Cumulative Results to Update Dichotomous Choice Contingent Valuation Offer Amounts

This study used cumulative results to update the distributions from which offer amounts were drawn in a dichotomous choice contingent valuation of user benefits from wilderness canoeing in Ontario's wilderness parks. An empirical model demonstrates the efficiency gains from using this procedure. Results allow comparison of variation in average daily willingness to pay (WTP) by trip length, indicating decreasing average benefits per trip-day. Two payment vehicles were used. Canoeists indicated ranges of WTPs which conformed to expected hypotheses when the payment vehicle was an increase in general trip costs. However, the same respondents indicated an upper bound on WTP when the payment vehicle was an increase in the provincial park backcountry permit price.
