The Uruguay Round and air pollution: estimating the composition,scale and technique effects of trade liberalization

This paper develops a methodology to estimate the environmental impact of the Uruguay Round trade agreement. The impact is estimated in terms of five air pollutants for both developed and developing countries/regions. The methodology estimates environmental Kuznets curves and uses these in conjunction with FranÇois et al.'s (1995) estimates of Uruguay Round income gains and sectoral production changes, together with sectoral pollution intensities from Hettige et al. (1994). In this manner, composition, scale and technique effects of the Uruguay Round on air pollution are estimated. The monetary cost/benefit associated with the pollution changes is also estimated. Results indicate that emissions of all five pollutants are predicted to increase in developing and transition regions as a result of the Uruguay Round, whilst in developed regions emissions of three pollutants decrease and two increase. The results also suggest that the environmental impact will be considerably greater if the Uruguay Round affects the rate of economic growth.     

Overseas Chinese Entrepreneurs: Second Force of Chinese Economy

Most of the foreign-funded enterprises in China are in fact funded by overseas Chinese. They have made indelible contributions to China‘s remarkable economic achievement. Their pioneering spirit has already been written into the glorious annals of China‘s economic development!……     

The environmental performance of firms: The role of foreign ownership, training, and experience

In this paper we extend the debate on the environmental implications of foreign direct investment in developing countries by examining a new mechanism through which foreign influence can affect the environmental performance of firms. We focus on the extent to which key workers who have had previous training or experience in a foreign owned firm transfer and utilise their knowledge gained to the benefit of the local environment. To this end we use detailed firm-level data on manufacturing firms in Ghana. Our econometric results suggest that the foreign training of a firm's decision maker does reduce fuel use, particularly so in foreign owned firms. Foreign ownership per se does not influence fuel use or total energy use but is found to increase electricity use, perhaps the cleanest form of energy used by Ghanaian firms.     

On the size and structure of group cooperation

When time preferences are heterogeneous and bounded away from one, how “much” cooperation can be achieved by an ongoing group? How does group cooperation vary with the group's size and structure? This paper examines characteristics of cooperative behavior in the class of symmetric, repeated games of collective action. These are games characterized by “free rider problems” in the level of cooperation achieved. The Repeated Prisoner's Dilemma games is a special case.We characterize the level of maximal average cooperation (MAC), the highest average level of cooperation, over all stationary subgame perfect equilibrium paths, that the group can achieve. The MAC is shown to be increasing in monotone shifts, and decreasing in mean preserving spreads of the distribution of discount factors. The latter suggests that more heterogeneous groups are less cooperative on average. Finally, in a class of Prisoner's Dilemma games, we show under weak conditions that the MAC exhibits increasing returns to scale in a range of heterogeneous discount factors. That is, larger groups are more cooperative, on average, than smaller ones. By contrast, when the group has a common discount factor, the MAC is invariant to group size.     

Harvest and extinction in multi-species ecosystems

A potential cost of harvesting in multi-species ecosystems is the extinction of nonharvested species that are at the same trophic level as the harvested species. Existing analytical models are not well-suited for studying this harvest externality because they focus on species interactions across trophic levels instead of within them. We identify the conditions under which the harvesting of a single species causes at least one extinction of nonharvested species at the same trophic level. We compare two harvest regimes: uniform management, in which a privately optimal harvest rate is applied to the entire ecosystem; and specialized management, in which a portion of the ecosystem is intensively managed for the harvested species and the rest is left unharvested. Which regime is more likely to result in extinction depends on the discount rate and on the harvested species' competitive ability and colonization rate compared to those of the other species.     

CordNet: Toward a distributed behavior model for emergency response coordination

Existing studies of coordination theory in human networks have looked at coordination problems requiring stable working relationships with no environmental uncertainties. With emergency response management demanding distributed coordination in volatile situations, the designs of existing models are useful as a building block, yet flawed for application. We hypothesize that changes to interconnectedness of nodes in the network may have implications on the potential to coordinate. To test our hypotheses, we investigate survey data from state law enforcement, state emergency services, and local law enforcement by performing agency‐based (macro) and cross‐agency (micro) analysis to identify attributes of each network and coordination.     

Deepwater energy industry impacts on economic growth and public service provision in Lafourche Parish,Louisiana

Oil and gas produced from active deepwater leases (over 1000 feet water depth) in the Gulf of Mexico as a percentage of total output increased from 27% in 1992 to 54% in 2005. This increase is requiring more land-based services. Port Fourchon's strategic location provides it with a competitive advantage as a supply base for a diverse set of deepwater oil and gas related activities, ranging from petroleum rig supply boats to the maintenance and repair of mobile drilling rigs. Further development of Port Fourchon as a supply base is expected to markedly impact Lafourche Parish. Community impact models (CIM) quantify the linkages among local economic activity and the demand for, and ability to support, local government services. A CIM developed for Louisiana, including an input–output module of the local economy, is used to evaluate the impact of the deepwater energy industry on the economy and government finances of Lafourche Parish. According to model results, the deepwater energy industry will continue to have a significant impact on that economy. By 2010, the industry was predicted to be directly and indirectly responsible for 2593 new jobs and $571 million in total output. Such activity should not strain the ability of local governments to deliver services.     

In Search of Environmental Spillovers

There is an extensive literature that examines the relationship between foreign direct investment (FDI) and the productivity and competitiveness of domestic firms. Using estimation techniques from the productivity spillover literature, this paper tests for the presence of environmental spillovers from foreign firms. On the basis that foreign‐owned firms may encourage firms in their extended supply chain to improve their environment‐related management practices, evidence for the existence of environmental spillovers should be easier to find than productivity spillovers where firms naturally attempt to minimise intra‐industry knowledge leakage. In this paper we show that, first, foreign‐owned firms are more likely to implement environmental management systems (EMS) and, second, that the presence of foreign‐owned firms in those sectors that a firm supplies can encourage good environmental practice. This is especially true if a firm is foreign, has high absorptive capacity, and operates in the presence of formal and informal networks.     

Examining the Relationships Between Monitoring and Incentives in Corporate Governance*

abstract Agency theory focuses on monitoring and incentives as two solutions to agency problems. Prior research suggests that monitoring and incentives may act either as substitutes or as complements, and that the context of the agency relationship plays a major role in determining the direction of the relationship between them. In a corporate governance setting, we contend that board information and boards' usage of CEO control mechanisms are best viewed as complements. Thus, we hypothesize that boards' information gathering behaviour will be positively related to boards' usage of CEO control mechanisms. Using primary and secondary data from 149 US firms, we find that increases in boards' information gathering are associated with increases in boards' usage of managerial controls. These findings suggest that information and managerial control mechanisms act as complements in the governance context, and that boards take a variety of actions to protect the interests of shareholders.
