Summary: This study aimed to identify variations in liver transplant access across different transplant referral regions, taking into account differences in population characteristics and practice environments. The study found that the proportion of patients living in poverty and concentrated poverty were negatively associated with the listing-to-death ratio (LDR) of liver transplants, while the organ donation rate was positively associated with LDR. The findings of this study are important for improving access to care for patients with end-stage liver disease.

Summary: This study shows that there is a significant cross-country variation in the relationship between bank competition and efficiency. On average, higher market power leads to greater bank efficiency, but this impact is more pronounced in countries with stricter capital regulation, better market discipline, greater official disciplinary power, more developed financial markets, lower levels of bank branch penetration, and lower credit information availability.

Summary: In the digital age, platforms utilize consumer data for personalized recommendations, leading to increased transaction rates. Our research examines the strategic use of consumer information by dual-sided platforms and its impact on pricing, consumer surplus, and social welfare. The findings indicate that platforms tend to exploit consumer information to standardize pricing strategies, but disparities in platform strengths can result in discriminatory pricing. Optimal balance between information utilization and pricing strategies leads to increased consumer surplus, while total social welfare decreases with competition.

Summary: This study analyzed multiple aspects of biosimilar competition of TNF-alpha inhibitors in Europe, including the existence of a biosimilar first-mover advantage and pricing strategies of originator companies. The findings showed that biosimilar entry increased utilization and reduced prices, but at a heterogeneous rate among different TNF-alpha inhibitors. Pricing strategies were found to affect market uptake.

Summary: We provide government spending efficiency scores for OECD countries and examine how capital markets perceive efficiency changes in determining sovereign ratings. Our analysis shows that higher public spending efficiency is rewarded with higher sovereign debt ratings. Additionally, inflation and government indebtedness lead to rating downgrades, while higher foreign reserves contribute to rating upgrades.

Summary: This paper examines the impact of government spending on default risk in emerging economies. The study finds that government spending shocks lead to increased external debt and sovereign bond spreads. Using panel data from 18 countries, the research also reveals that a 10% increase in government spending results in a 1.0% appreciation of the real effective exchange rate, a deterioration of 0.0025 in the current account to GDP ratio, an average increase of 3.5% in external debt in the year following the shock, and a rise of 25 basis points in the EMBI Global spread within two years, peaking at 132 basis points after 14 quarters, indicating a higher sovereign default risk.

Summary: This study aimed to define geographic variations in emergency general surgery care. Widespread geographic differences were found in rates of EGS operations and subsequent mortality across 6 Northeastern and Southeastern US states. Further research is needed to determine the reasons behind these variations and how to minimize them.

Summary: There is significant variation in bariatric surgery utilization between states in the United States, with nearly a 5-fold difference between the states with the highest and lowest utilization rates. The Northeast region had the highest rates while the Midwest had the lowest. Different states also showed variations in the proportion of sleeve gastrectomies performed.

Summary: We explore the relationship between product market competition and innovation in technology markets. Our study finds that there is a U-shaped relationship between competition in licensee product markets and innovation in the technology market. At low levels of competition, market-wide licensing is optimal and competition reduces innovation. However, at high levels of competition, targeted licensing is optimal and competition increases innovation. Our empirical analysis using a large panel of U.S. data provides clear support for these predictions.

Summary: This study suggests that increased competition in subprime consumer credit markets, where lenders use fixed-cost technologies to screen borrowers, may lead to higher interest rates. In more competitive markets, lenders have lower market shares and lower incentives to invest in screening, resulting in a riskier pool of borrowers and higher interest rates.

Summary: In this study, we examine the variations of health-care spending in different regions of China based on a nationwide sample of inpatients insured under the urban basic medical insurance schemes in 2010. The findings indicate significant geographic variations in health-care spending in China, primarily driven by differences in quantity. The study also suggests potential allocation inefficiency in China's current urban health-care system.

Summary: This study assesses the regional variation in long-term care (LTC) spending across municipalities in Japan and identifies the drivers of such variation. The findings reveal a significant regional disparity in LTC spending, even after adjusting for population characteristics, with demand factors contributing the most to the overall variance.

Summary: The study evaluated the utilization and spending on buprenorphine formulations in Medicaid, finding that brand-name formulations were more widely used and costly than generic versions due to delays in their availability caused by market and regulatory factors.

Summary: In this study, we investigate the impact of platform integration on system efficiency in a ride-sourcing market with multiple competing platforms. We find that platform integration can increase overall demand and social welfare, but may not necessarily lead to higher profits when there is sufficient vehicle supply or the market is highly fragmented. The market with platform integration generally achieves greater social welfare due to reduced matching frictions and lower trip fares set by multiple platforms competing for passengers.

Summary: The study explores how network interconnectivity affects competition between incumbent and entrant platforms. Markets with more mobile buyers may reduce the incumbent's incentive to fight, increasing the entrant's incentive to expand. However, the level of interconnectivity between markets can have complex effects on the incumbent's competitive defensibility.
