Inventory, investment, and pricing policies for lot-size decision makers

In this dissertation, inventory, investment, and pricing policies for lot-size decision makers are examined based on classical economic order quantity. Specifically, we focus on investment in setup operations, investment in quality improvement, and market dependent products such as substitutes and complements. We examine various impacts of investment and competition on inventory policies and derive managerial insights and economic implications. Throughout this dissertation, deterministic mathematical programming is used as the primary analysis technique and optimal policies are obtained through this technique;For the inventory and investment relationships, we construct and analyze inventory and investment in setup operations policies, inventory and investment in quality improvement policies, and inventory and capital investment allocation policies in setup and quality operations under ROI maximization. The resulting contributions are the establishment of an ROI model with/without the capital budget constraint and characterization of the unique global optimal solution when there exists an option to invest in setup operations. We also show how the inventory level is reduced when it is optimal to invest additional money in setup operations and/or quality improvement;For the inventory and competition relationships, on the other hand, we design and analyze two duopoly models for two profit maximizing sellers when products are substitutes or complements. The resulting contributions are formulation of inventory and pricing policies for substitutes and complements. Furthermore, we obtain the closed-form inventory and pricing policies at equilibrium when symmetric demand and cost are assumed

The Impact of Soil Conservation Policies on Carbon Sequestration in Agricultural Soils of the Central United States

To evaluate the impact of conservation policies on soil organic carbon in agricultural soils, the authors link information from the 1992 National Resources Inventory (NRI) database and the extensive physical data on soils and climate from the SOILS5 database. These data serve as input for a biophysical process model calibrated for the conditions prevalent in the study region. Results indicate that reducing soil erosion, rather than removing land from agricultural production, is the most effective way to increase carbon sequestration and enhance soil quality

Corn and Sorghum Herbicides and Water Quality: An Evaluation of Alternative Policy Options

The policies restricting the use of atrazine and other triazines to achieve desirable water quality standards are analyzed in a CEEPES framework. Five policies, including atrazine post restriction, restricting atrazine to meet MCL and HAL standards in runoff, a complete ban on atrazine, and also a ban on all triazines, were evaluated. The results suggest a $764 million total economic welfare loss with a triazine ban; with all other policies there was only one-third as much economic welfare loss. Although the triazine ban produced desirable water quality benefits, the economic costs are significantly higher. The overall goal of reducing water quality risk with the least economic welfare loss would not be achieved through an atrazine ban either, unless producers adopt practices that minimize risk from substitute herbicides. The runoff standards-based policy restrictions and atrazine post restriction offer best results for minimizing environmental risks with the least welfare reduction, but the current analysis assumes zero transaction costs, namely zero cost of monitoring and assessment

Inventory and investment in setup operations under return on investment maximization

[[abstract]]In this paper, we construct and analyze inventory and investment in setup operations policies under return on investment (ROI) maximization. The key contributing features of this paper are the establishment of an ROI model and characterization of the unique global optimal solution when there exists an option to invest in setup operations. We also show how the inventory level is reduced when it is optimal to invest additional money in setup operations and derive the unique optimal solutions in closed-form when the setup cost is a rational or linear function of the level of investment. Various interesting managerial insights are provided.[[notice]]補正完

Credit Participation and Credit Source Selection of Vietnam Small and Medium Enterprises

This study is an attempt to investigate the motivation behind the decision to participate in the credit market of SMEs from perspectives of behavioral finance and social capital theories. In addition, the study also examines the effect of behavioral finance and social capital factors on the credit source selection among SMEs. This study&rsquo;s design strategy involves conducting questionnaire surveys to SMEs owners and statistical techniques to analyze the determinants of credit participation and credit source selection of borrowers. The findings showed that personal traits of SMEs owners/managers in terms of behavioral finance factors such as debt and risk attitudes, present biased and overconfidence and firms networking also have impacts on the firms&rsquo; credit participation and credit source selection. The research is one of the few studies that consider the influence of behavioral finance factors on firms financing decision. Furthermore, our result also contributes to explain thecommon use of informal credit market in developing countries.&nbsp
