Summary: This paper addresses the issue of a monopolist firm's decision on designing environmentally friendly products while facing high research and development costs. A mathematical model is used to examine the impact of government subsidies on the firm's choice between mass marketing and market segmentation. The firm's response to the subsidies is analyzed through a two-stage Stackelberg game. The findings show that the subsidy level does not affect the relationship between the environmental qualities of the products under different marketing strategies when the green market is weak. Our analysis also highlights the importance of selecting an optimal subsidy level to maximize social welfare and how this optimal subsidy is influenced by factors such as development costs.

Summary: This paper compares the social welfare effects of carbon taxes and subsidies, indicating that as the environmental damage of high carbon products increases, the policy instrument should shift from subsidies to carbon taxes. Additionally, it is shown that when the government intervenes with pollution control policies, Bertrand competition does not always result in higher social welfare than Cournot competition.

Summary: Biopesticides are effective in combating environmental consequences from chemical pesticides, but their high prices and unreasonable government subsidies pose challenges for pesticide supply chains. This study analyzed the production and sales strategies of pesticides in monopoly and duopoly markets, and found that government subsidies within a reasonable range incentivize manufacturers to produce biopesticides. The subsidy improves the profit of the pesticide supply chain in monopoly market, while consumer surplus and social welfare are greater in the duopoly market. Launching biopesticides reduces environmental pollution in both market structures, with less impact in the monopoly market.

Summary: The guaranteed support price (GSP) scheme aims to support farmers and the underprivileged population in developing countries through supply-side incentives, demand-side provisioning, and food security measures. Analyzing the scheme against direct benefit transfer (DBT), it is found that the surplus under GSP is higher when the value of food security is significant, while the production by farmers is influenced by the poverty level of consumers and yield uncertainty. When poverty is extreme, GSP and DBT result in similar production levels, but if yield uncertainty is high, GSP can strategically induce higher production compared to DBT.

Summary: This study explores the optimal strategy for governments to provide subsidies in the vaccine market through a game-theoretic model, suggesting that governments should publicize the benefits of vaccines to raise consumer awareness levels and increase vaccination rates. It is optimal for the government to subsidize consumers rather than vaccine manufacturers, and to provide subsidies for both informed and uninformed consumers, regardless of vaccine price settings.

Summary: This paper examines the impact of corruption on stock market development, highlighting the difference between developing and developed economies and the role of corruption in hindering firms from listing. Using a theoretical model, the study tests for this difference using data from 87 economies over the period 1995-2017. The results show that corruption does not have a significant effect on stock market development for the entire sample, but there is a significant relationship between lower levels of corruption and stock market capitalization as a share of GDP for high-income countries.

Summary: Content-sharing social network platforms rely on user-generated content and face limited control over content provision. This study explores the use of social nudges to stimulate content production through social interactions between users. The results show that social nudges immediately increase content supply without affecting quality and also lead to more nudges sent by providers. These effects persist over time and are amplified when there are stronger ties between senders and recipients. The research highlights the value of leveraging co-user influence and provides guidance for incorporating intervention diffusion in social network estimation.

Summary: Shared micromobility vehicles provide an eco-friendly form of short-distance travel within an urban area. To overcome the imbalance between vehicle supply and demand in different service regions, a micromobility operator can use reward incentives and engage a third-party logistics provider (3PL) for vehicle relocation. The study proposes a two-stage stochastic mixed-integer program to optimize vehicle allocation and relocation, and the results show that incorporating rider crowdsourcing and 3PL can increase profit and improve system efficiency.

Summary: When supply disruptions occur, firms need to employ the right pricing strategy. Fixed pricing strategy offers stability but lower profit, while naive pricing strategy brings higher profit. One-period correction strategy results in volatile customer order process and smaller profit. Regression pricing strategy, though advanced, leads to lower profit and greater customer order variability. It is advisable to adjust price to match supply and demand and not eliminate customer order variability completely.
