This research uses neighborhood characteristics (at the zip code level) in 1990 to explain toxic releases in 1993. It combines the Toxics Release Inventory data with demographic data from the 1990 U.S. Census. We first analyze the location of manufacturing facilities in a particular neighborhood using a sample selection model, and then estimate the relationship between releases in 1993 and the demographic characteristics of the neighborhood in 1990. We conduct the analysis for the entire U.S. as well as for different geographic regions to study regional differences in determinants of environmental outcomes. Releases in nonurban areas of the southeastern U.S. exhibit a pattern suggesting that race might be an important determinant of release patterns. Economic characteristics of neighborhoods (such as income levels and unemployment) also affect releases. Our variables that proxy the propensity for communities to engage in political action exert greater influence on environmental outcomes in nonurban areas. 相似文献

The competitive free-for-all that Congress envisioned in the 1996 Telecommunications Act has for the most part not appeared. The Act calls for two forms of regulatorily-assisted entry into local markets: lease of network elements and resale. The FCC has decreed that the charges for those elements and the resale discounts must emulate the costs of an ideally-efficient firm. This standard is in fact not efficient, and the FCC’s attempt to jump-start the entry of competitors in this way has short-circuited the competitive process itself and jeopardized achievement of the goals of the Act. 相似文献

Opinion leaders propel the diffusion of innovation and exert a significant influence on the marketplace. This influence is especially pronounced during adolescence, a period marked by increasing reliance on peers and the emergence of a tension between two countervailing needs: assimilation and individuation. A survey of 1142 adolescents reveals that these developmental needs affect adolescent opinion leadership in the critical clothing market. Adolescent opinion leadership relies on a balance between desires for assimilation (i.e., centrality within the peer network) and individuation (i.e., need for uniqueness); adolescents' susceptibility to peers' normative influence and gender moderate these relationships. Adolescents who occupy central positions within their peer network tend to be opinion leaders, though only if they are not susceptible to normative influence. Position within the peer network is a key for girls, whereas need for uniqueness is a key for boys. These differences implicate different approaches for managers targeting adolescent males and females. 相似文献

Retail futures traders face uncertainty regarding the price they will obtain when trading. This price "surprise," known as slippage, can be substantial. Using unique data from an introducing brokerage for Chicago Board of Trade (CBOT) wheat, corn, and soybean futures contracts, we quantify time-to-clear and the magnitude of slippage. We then identify factors that affect these trade quality measures. Finally, we analyze individual trader choice between market and limit orders and find that the likelihood of placing limit orders, where regulations protect traders from slippage, is greater when order and market characteristic indicate that adverse slippage is likely. 相似文献

Formative versus reflective measurement models: Two applications of formative measurement 总被引:1,自引:0,他引:1

This paper presents a framework that helps researchers to design and validate both formative and reflective measurement models. The framework draws from the existing literature and includes both theoretical and empirical considerations. Two important examples, one from international business and one from marketing, illustrate the use of the framework. Both examples concern constructs that are fundamental to theory-building in these disciplines, and constructs that most scholars measure reflectively. In contrast, applying the framework suggests that a formative measurement model may be more appropriate. These results reinforce the need for all researchers to justify, both theoretically and empirically, their choice of measurement model. Use of an incorrect measurement model undermines the content validity of constructs, misrepresents the structural relationships between them, and ultimately lowers the usefulness of management theories for business researchers and practitioners. The main contribution of this paper is to question the unthinking assumption of reflective measurement seen in much of the business literature. 相似文献

Controlling for spatial effects in micro‐level studies of consumer and producer behaviour necessitates a range of analytical modifications. These range from modest changes in data collection and the definition of variables to dramatic changes in the modelling of consumer and producer decision‐making. This paper discusses conceptual, empirical and data issues involved in modelling the spatial aspects of economic behaviour in data‐rich environments. Attention is given to established and emerging agricultural economic applications of spatial data and spatial econometric methods at the micro‐scale. Recent applications of individual and household data are featured, including models of land‐use change at the urban–rural interface, agricultural land values, and technological change and technology adoption. 相似文献

The U.S. has had significant trade deficits in insurance for several years. This paper examines the reasons for such big annual deficits. A large home market, a low reinsurance capacity, and the conservative attitude of U.S. insurers toward foreign markets are identified as the primary contributors to such deficits. The paper also addresses the issue of how U.S. insurers can improve their international competitive position. By expanding their operations abroad, particularly in Mexico and Latin America, and by actively participating in the fast-growing Asian markets, American insurers have their greatest chance to accomplish that objective. 相似文献

The United States has experienced a dramatic increase in foreign direct investment (FDI) in recent years. While foreign firms bring immediate benefits of high‐paying jobs, data limitations have prevented detailed study on FDI's long‐term effects on the states receiving it. By creating a new stock measure of FDI based on employment, we are able to capture these long‐term effects. Results demonstrate that FDI has a greater impact on per capita output growth than domestic investment for US states that meet a minimum human capital threshold. Ironically, the most active states in the recruitment of FDI tend to fall below this threshold. 相似文献
