Optimizing Healthcare Ecosystem Performance-A Computational Study of Integrated Patient Assistance in Primary Care
Full text linkHome health care professionals provide medical services to patients in their homes. With rising demand, it’s crucial to manage operational costs effectively while ensuring satisfaction for patients. This study presents a bi-objective optimization model aimed at resolving routing and scheduling challenges in home health care, with a focus on both system efficiency and patient accessibility. A Mixed-Integer Linear Programming Model (MILP) is developed. To tackle computational time challenges, we propose a Non-dominated Sorting Genetic Algorithm II to solve the multi-objective optimization problems. The evaluation of Pareto fronts demonstrates the method’s efficiency. We apply the method in a real-world case study to provide managerial implications

Imports and credit rationing: A firm-level investigation
No full textFirm performance is known to benefit from participation in import markets. For this reason, understanding whether credit constraints hamper firms’ ability to purchase foreign inputs is a relevant issue. In this paper, we investigate the relationship between financial constraints and imports of intermediate inputs using a large sample of small- and medium-sized enterprises from 66 developing countries. To measure credit constraints, we use information from a firm's in-depth self-assessment of its difficulties in having access to external finance. Furthermore, to tackle the endogeneity problems in the estimation, we rely on an instrumental variable approach that allows us to establish more directly the impact of financial constraints on importing activities. We provide statistically and economically significant evidence that credit-constrained firms have a lower probability of importing intermediates (the extensive margin) and a smaller share of imported intermediates in their total input expenditure (the intensive margin). Moreover, we show that the impact on these margins of import is stronger for firms operating in countries where the financial system is less developed, the quality of institutions poorer and the overall level of economic freedom lower
