Summary: Through a differential game model on multiregional transboundary pollution, we find that at equilibrium, the emission levels and locations of each region vary depending on the specific geographical relationships among agents. Geographical considerations can affect players' optimal strategies, emphasizing the importance of spatial aspects in the model.

Summary: In a heterogeneous two-country differential game setting, competitiveness considerations lead to different carbon taxes being set by countries, suggesting a universally homogeneous policy may not be optimal. In a noncooperative environment, introducing competitiveness concerns reduces abatement policies in both countries, with the self-effect being stronger than the cross-effect. Under cooperation, an increase in one country's competitiveness concerns results in more stringent policies in another country, with the self-effect potentially being positive or negative. This highlights the importance of cooperation in addressing pollution in the presence of competitiveness concerns.

Summary: A year-long intensive observation of the atmospheric boundary layer (ABL) at multiple sites in Hong Kong using a four-Doppler Light Detection and Ranging (LiDAR) network with different scanning modes revealed the heterogeneity of the ABL induced by orographic topography, as well as the interaction between local and advected aerosol layers during a transboundary air pollution (TAP) episode.

Summary: This paper proposes a strategy to alleviate transboundary air pollution by coordinating regional economic interests and environmental preferences. The optimal solution is derived using a stochastic differential game model, and numerical simulations show that the dynamic PES strategy outperforms other strategies. The confidence interval theory is used as a diagnostic tool for policy-makers.

Summary: This study applies inter-temporal transfer of emission permits to transboundary pollution for the first time, considering spatial dimensions and using differential game theory. The findings suggest that if the cost fluctuation is significant, regulators should prohibit inter-temporal banking and borrowing. Additionally, the region with geographical advantage loses its advantage under the cooperative model.

Summary: This study focuses on the issue of transboundary pollution and proposes a long-term abatement technology solution. By establishing a differential game model, the authors find that fixed-fee licensing is superior and beneficial for both regions. The analysis also shows that myopic behavior leads to short-term revenue maximization and increased total pollution stock. Additionally, a high level of abatement technology or emission tax prompts the licensee region to choose fixed-fee licensing.

Summary: We analyzed PM2.5 concentrations measured at the U.S. Embassy in Dhaka from 2016 to 2021 and found that they vary seasonally, with the highest levels in winter and the lowest in monsoon seasons. Winter mean PM2.5 concentrations reached approximately 165-175 μg/m³, while monsoon concentrations remained around 30-35 μg/m³. The annual mean PM2.5 concentration was about 5-6 times higher than the Bangladesh annual standard of 15 μg/m³. The number of days exceeding the daily PM2.5 standard of 65 μg/m³ approached nearly 50%.

Summary: In this study, the strategic impact of a region's investment in cleaner technology on the equilibrium outcomes and regions' welfare in a noncooperative transboundary pollution dynamic game is explored. The analysis shows that the ratio of emissions to output is endogenous and investing in cleaner technology can improve regions' welfare. This investment benefits both regions as cleaner technology is assumed to be public knowledge.

Summary: This paper uses a dynamic multi-game model to analyze the pollution control game behavior of upstream and downstream regions along the basin and obtain the dynamic equilibrium strategies and pollution trajectories under different cooperation modes. The results show that pollution abatement cooperation can improve the environment but may not necessarily improve social welfare. The eco-compensation mechanism is not always beneficial for the improvement of the basin's environment and welfare, and the effective conditions for implementing ecological compensation are proposed. Additionally, the impact of consumer preferences, pollution treatment efficiency, and other parameters on decision-making and social welfare are analyzed. These conclusions provide a theoretical basis for cooperative governance schemes for transboundary pollution in river basins.

Additionally, manufacturers should avoid outsourcing demand-enhancing services to third parties in order to maintain the service level provided to customers.

Summary: This paper investigates the optimal allocation of resources to retailer-initiated and manufacturer advertising in a bilateral monopoly market. The findings suggest that manufacturers should avoid exclusively offering cooperative advertising programs to retailers and should consider undertaking their own advertising in addition to supporting retailer advertising. Both manufacturers and retailers prefer scenarios where both parties advertise simultaneously.

Summary: The Connected Max-k-Cut Problem is an extension of the well-known Max-Cut Problem, where the objective is to partition a graph into k connected subgraphs by maximizing the cost of inter-partition edges. The researchers propose a new integer linear program and a branch-and-cut algorithm for this problem, and also use graph isomorphism to structure the instances and facilitate their resolution. Extensive computational experiments show that, if k > 2, their approach outperforms existing algorithms in terms of quality.

Summary: This paper studies a variant of the orienteering problem known as the clustered orienteering problem. In this problem, customers are grouped into clusters and a profit is associated with each cluster, collected only when all customers in the cluster are served. The proposed evolutionary algorithm, incorporating a backbone-based crossover operator and a destroy-and-repair mutation operator, outperforms existing algorithms on benchmark instances and sets new records on some instances. It also demonstrates scalability on large instances and has shown superiority over three state-of-the-art COP algorithms. The algorithm is also successfully applied to a dynamic version of the COP considering stochastic travel time.
