Invasive species management in a spatially heterogeneous world: Effects of uniform policies

The spread of invasive species (IS) is an inherently spatial process, and management of invasive species occurs over spatially heterogeneous regions, but policy constraints can restrict management responses to be homogeneous across regions. Using a spatial bioeconomic model that includes a representation of invasive species ecology based on heterogeneous environments that are linked across space and time by human and ecological pathways, we compare optimal spatially heterogeneous policy to spatially uniform policy. We explore the magnitude and pattern of the policy differences with emphasis on the influence of different types of underlying heterogeneity across locations.     

International trade and unionization: Evidence from India

We exploit exogenous variation in tariffs to examine the impact of import competition on unionization and union wages in a developing country. Using a combination of nationally representative household data (National Sample Survey Organization) and nationally representative industry‐level data (Annual Survey of Industries) from India, we find that net‐import industries that experienced larger cuts in tariffs also experienced larger declines in unionization. In addition, we find that these industries also experienced larger increases in union wages. These results are consistent with the predictions of an efficient bargaining framework that we extend to endogenize the union formation decision by allowing for a fixed cost of union formation. We also conduct a back‐of‐the‐envelope calculation to show that the total wage gains to unionized workers marginally exceed the total wage losses to deunionized workers.     

Measuring new product success: an empirical investigation of Australian SMEs

New product development (NPD) has long been recognised as one of the corporate core functions. However, measuring new product success has remained elusive. This paper attempts to examine several conceptual issues underlining the measurement of new product success and the measurement practice adopted in Australian small and medium enterprises (SMEs). The sample included 276 SMEs from two most innovative industries: chemical and machinery industries. Results have indicated that four factors underline the commonly used success measurement: financial performance, objective market acceptance, subjective market acceptance, and product-level measures. These four factors are related to each other and can be used to well predict the overall measurement. The most frequently used specific measures in Australian SMEs are customer acceptance, customer satisfaction, product performance, and quality.     

Public sector health insurance trusts

Public sector associations have successfully developed and run employee health insurance pools for almost 30 years, providing members with savings and flexibility not available from commercial health insurance carriers. This article looks at the models, technical tools and governance philosophy that have contributed to their success in a very challenging business environment.     

Relationship marketing in consumer markets: Antecedents and consequences

Understanding the motivations of consumers to engage in relationships with marketers is important for both practitioners and marketing scholars. To develop an effective theory of relationship marketing, it is necessary to understand what motivates consumers to reduce their available market choices and engage in a relational market behavior by patronizing the same marketer in subsequent choice situations. This article draws on established consumer behavior literature to suggest that consumers engage in relational market behavior due to personal influences, social influences, and institutional influences. Consumers reduce their available choice and engage in relational market behavior because they want to simplify their buying and consuming tasks, simplify information processing, reduce perceived risks, and maintain cognitive consistency and a state of psychological comfort. They also engage in relational market behavior because of family and social norms, peer group pressures, government mandates, religious tenets, employer influences, and marketer policies. The willingness and ability of both consumers and marketers to engage in relational marketing will lead to greater marketing productivity, unless either consumers or marketers abuse the mutual interdependence and cooperation. He has published more than 200 books and research papers in different areas of marketing. His bookThe Theory of Buyer Behavior (1969) with John A. Howard is a classic in the field. He has recently published two scholarly books:Marketing Theory: Evolution and Evaluation (1988) andConsumption Values and Market Choices (1991). He is on the editorial boards of at least a dozen scholarly journals in marketing, international business, and quantitative methods; he is also series editor ofResearch in Marketing (JAI Press). Prior to joining Emory, he was an associate professor of marketing at XLRI Jamshedpur in India. He received his M.B.A. and Ph.D. from Banaras Hindu University, India. He has authored a number of articles in the area of international marketing, business alliances, and environmental marketing. He is coeditor ofResearch in Marketing (Annual Series, JAI Press) and serves on the editorial review board ofInternational Marketing Review.

Analysis of Visitor Decision Making System When Visiting Natural Recreation Sites by Multinomial Logit Model

Multinomial Logit Model has analyzed the relationship between the frequency of visits to recreation areas and the motivational factors affecting the visits. Kastro Environment Preserving Site that is located in the Black Sea coast of Marmara region in Turkey, has been chosen as the site for this study. Kastro bay is a natural park that is visited only for recreational visits. The study has been conducted on a photogenic study group due to the proximity factor of Kastro bay close to Istanbul. Kastro bay is a popular recreational park due to its characteristic advantages such as a 200 m wide and approximately 2.5 km long beach and with its high quality vegetation. The vegetation type includes ash tree, oak tree, black pine, sand lily etc. Kastro bay is also the site for the Mediterranean seals (Monachus-monachus) which are at the level of extinction. Approximately 50,000 visitors visit the region during the months of July and August. It has been concluded that there is high direct correlation between the frequency of visits and the motivational factors. It has been determined that the visits are mostly based on the sea and the ecological tourism.Jel: O13, Q20, Q26, Q51, Q56, Q57     

OCCUPATIONAL EARNINGS BEHAVIOR AND THE INEQUALITY OF EARNINGS BY SEX AND RACE IN THE UNITED STATES*

This paper examines differences in earnings by occupations, and within occupations by sex and by race, on the basis of the 1/100 Public Use Samples of the 1960 and 1970 U.S. Population Censuses. It employs interval analysis to establish 32 categories of occupations with similar characteristics. Little relation was found between mean earnings of occupational groups and the degree of earnings inequality within them. When the figures are examined by sex, it was found that men, on average, earned over twice as much as women in both years, but women's earnings were more unequally distributed (as measured by the Gini coefficient). Women are concentrated in the traditional “female” occupations, which tend to be those at the bottom of the earnings scale, and men have a monopoly of the higher paid occupations. But mean earnings for men exceeded those for women in all occupational groups except one, even in the primarily female occupations. Standardizing first for occupational distribution and then for earnings by occupation, it was found that earnings differences between males and females within occupation had a greater impact on the overall male-female earnings ratio than did differences in occupational distribution by sex. In contrast, when the figures are examined by race, the change in occupational distribution (primarily the movement of blacks out of farming and of blacks and Spanish speakers out of personal services) was the major factor. There was also a considerable degree of earnings inequality within demographic groups. The degree of inequality was in the main reduced when the demographic groups were subdivided into occupations, but it was still substantial. Additional factors like time worked, schooling, and experience must be taken into consideration in understanding this phenomenon.
