RESUMEN

This study investigates the relationship between consumer sentiment (CONS), inflation expectations (INEX) and international energy prices, drawing on principles from behavioral. We focus on Brent crude oil price and Henry Hub natural gas prices as key indicators of energy market dynamics. Based on the monthly data from January 2003 to March 2023, three wavelet methods are applied to examine the time-frequency linkage, while the nonlinear distributed lag model (NARDL) is used to verify the asymmetric impact of two factors on energy prices. The results highlight a substantial connection between consumer sentiment, inflation expectations and international energy prices, with the former in the short term and the latter in the medium to long term. Especially, these correlations are particularly pronounced during the financial crisis and global health emergencies, such as the COVID-19 epidemic. Furthermore, we detect short-term asymmetric effects of consumer sentiment and inflation expectations on Brent crude oil price, with the negative shocks dominating. The positive effects of these factors on oil prices contribute to observed long-term asymmetry. In contrast, inflation expectations have short-term and long-run asymmetric effects on natural gas price, and both are dominated by reverse shocks, while the impact of consumer sentiment on natural gas prices appears to be less asymmetric. This study could enrich current theories on the interaction between the international energy market and serve as a supplement to current literature.

RESUMEN

Exchange rate pass-through (ERPT) represents a degree to which changes in nominal exchange rates are transmitted into domestic prices. European Union (EU) countries have experienced the unprecedented inflationary pressure due to high geopolitical risk events. As such, understanding the ERPT plays a crucial role. This study provides a comprehensive and up-to-date analysis of ERPT to import prices for 16 EU countries from January 2006 to December 2022. Using the panel autoregressive distributed lag (ARDL) model, our findings confirm the linear, rather than nonlinear, ERPT pattern characterized by a diminishing trend over time in the EU countries. However, the degree of pass-through varies depending on country characteristics. Specifically, countries that are highly dependent on imports experience a larger ERPT. Furthermore, the degree of pass-through to import prices is more significant and persistent during periods of high uncertainty. These findings are robust across various robust analyses including sub periods. Our findings provide that help policymakers evaluate the trade-offs between exchange rate risks and macroeconomic stability during times of high uncertainty.

RESUMEN

The study draws attention to the associations between monetary and economic elements and their potential environmental impacts. The study uses time series data from 1960 to 2022 to examine the connection between CO2 emissions, industrial growth, GNE, and inflation in China. The researchers utilized the well-known econometric technique of nonlinear autoregressive distributed lag (NARDL) to examine nonlinear correlations between these variables. The results reveal that GDP, inflation, and economic development influence long-term CO2 emissions. The strong positive correlation between gross national expenditures and economic activity increases CO2 emissions. In the short run, CO2 emissions are positively and statistically significantly affected by inflation. While inflation temporarily affects CO2 emissions, this effect dissipates with time. Industrial activity increases CO2 emissions, and China's fast industrialization has damaged the environment. The energy-intensive fertiliser manufacturing process and fossil fuels increase CO2 emissions. The research shows how government officials and academics may collaborate to create tailored measures to alleviate the environmental impacts of economic activity.

RESUMEN

STUDY OBJECTIVE: Identify changes and trends in the real value of Medicare payments for anesthesia services between 2000 and 2020 and how it may affect practices. DESIGN: Retrospective analysis. SETTING: We utilized the Physician/Supplier Procedure Summary (PSPS) datasets of Medicare Part B claims to identify high volume anesthesia services in 2020 with 20 years of data. The Consumer Price Index was used as a measure of inflation to adjust prices. PATIENTS: The PSPS datasets contain summaries of all annual Medicare Part B claims and payment amounts by carrier and locality. INTERVENTIONS: Patients receiving anesthesia services. MEASUREMENTS: For each service, identified by Current Procedural Terminology (CPT) codes, we trended the average Medicare payment per procedure from 2000 to 2020 and calculated year to year changes and compound annual growth rate (CAGR). We also evaluated base and time units for each CPT code and the national Medicare anesthesia conversion factor (CF) for the same years. MAIN RESULTS: The average Medicare payment in the study sample increased 20.1% from 2000 to 2020. After adjusting for inflation, the average Medicare payment per anesthesia service decreased by 20.8% over that period. The Medicare anesthesia CF increased 24.9% in the same period, and after adjusting for inflation, the real value of the CF decreased 16.9%. Average CAGR across the 20 anesthesia services was 0.88%, compared to the average annual inflation at 2.06%. CONCLUSIONS: Average Medicare payment for common anesthesia services after adjusting for inflation have decreased from 2000 to 2020, consistent with findings in other physician specialties. Understanding these trends is important for practice viability and suggests significant financial implications for anesthesia practices and hospitals if the trend were to continue.

RESUMEN

The product market competition affects the non-neutrality of monetary policy. This paper quantitatively assesses its impact on the slope of the Phillips curve through the channels of nominal and real rigidity. We build a New Keynesian model using the Kimball aggregator and the Calvo staggered pricing scheme. We show that a more competitive market environment has opposite effects on the slope of the Phillips curve by increasing the real rigidity and lowering the nominal rigidity. We then estimated the model using regional data of China. The Bayesian estimation shows that the response of inflation-output trade-off is larger in the region with a high degree of competition. Counterfactual experiments demonstrate that nominal rigidity has a dominant role and accounts for the majority of the difference in the Phillips curve, while the contribution of real rigidity is relatively minor. Our results highlight the key role of nominal rigidity in determining the inflation-output dynamics.

RESUMEN

OBJECTIVE: This study aimed to analyze the trends of Medicare physician reimbursement from 2011 to 2021 and compare the rates across different surgical specialties. BACKGROUND: Knowledge of Medicare is essential because of its significant contribution in physician reimbursements. Previous studies across surgical specialties have demonstrated that Medicare, despite keeping up with inflation in some areas, has remained flat when accounting for physician reimbursement. STUDY DESIGN: The Physician/Supplier Procedure Summary data for the calendar year 2021 were queried to extract the top 50% of Current Procedural Terminology codes based on case volume. The Physician Fee Schedule look-up tool was accessed, and the physician reimbursement fee was abstracted. Weighted mean reimbursement was adjusted for inflation. Growth rate and compound annual growth rate were calculated. Projection of future inflation and reimbursement rates were also calculated using the US Bureau of Labor Statistics. RESULTS: After adjusting for inflation, the weighted mean reimbursement across surgical specialties decreased by -22.5%. The largest reimbursement decrease was within the field of general surgery (-33.3%), followed by otolaryngology (-31.5%), vascular surgery (-23.3%), and plastic surgery (-22.8%). There was a significant decrease in median case volume across all specialties between 2011 and 2021 (P < 0.001). CONCLUSIONS: This study demonstrated that, when adjusted for inflation, over the study period, there has been a consistent decrease in reimbursement for all specialties analyzed. Awareness of the current downward trends in Medicare physician reimbursement should be a priority for all surgeons, as means of advocating for compensation and to maintain surgical care feasible and accessible to all patients.

RESUMEN

BACKGROUND: Transcatheter aortic valve replacement has become an accepted alternative to surgical aortic valve replacement. We examined the trends and predictors in inflation-adjusted costs of transcatheter aortic valve replacement and surgical aortic valve replacement. METHODS: National Inpatient Sample identified patients who underwent aortic valve replacement for severe aortic stenosis by International Classification of Diseases, Ninth and Tenth Revisions, codes. Hospitalization costs were inflation-adjusted using the Federal Reserve's consumer price index to reflect current valuation. Outcomes of interest were unadjusted trend in annual cost for each procedure and predictors of in-patient cost. Generalized linear models with a log link function identified predictors of adjusted costs. Interaction terms determined where cost predictors were different by operation type. RESULTS: Between 2011 and 2019, the mean annual inflation-adjusted cost of surgical aortic valve replacement increased from $62,853 to $63,743, in contrast to decreasing cost of transcatheter aortic valve replacement from $64,913 to $56,042 ($1,854 per year; P = .004). Significant independent predictors of patient-level cost included operation type (transcatheter aortic valve replacement associated with $9,625 increase; P < .001), incidence of in-hospital mortality ($28,836 increase; P < .001), elective status ($2,410 decrease; P < .001), Elixhauser Index ($995 increase; P < .001), and postoperative length of stay ($2,014 per day increase; P < .001). Compared to discharges with Medicare, discharges with private insurance and Medicaid paid $736 less (P = .004) and $1,863 less (P = .01), respectively. Increasing hospital volume was a significant predictor of decreasing patient level cost (P < .001). CONCLUSION: Annual cost of transcatheter aortic valve replacement has decreased significantly and has been a more cost-effective modality compared to surgical aortic valve replacement since 2017. Predictors of patient-level costs allow for mindful preparation of healthcare systems for aortic valve replacement.

RESUMEN

BACKGROUND: Malnutrition poses a substantial challenge in Somalia, impacting approximately 1.8 million children. This critical issue is exacerbated by a multifaceted interplay of factors. Consequently, this study seeks to examine the long-term and short-term effects of armed conflicts, food price inflation, and climate variability on global acute malnutrition in Somalia. METHODS: The study utilized secondary data spanning from January 2015 to December 2022, sourced from relevant databases. Two distinct analytical approaches were employed to comprehensively investigate the dynamics of global acute malnutrition in Somalia. Firstly, dynamic autoregressive distributed lag (ARDL) simulations were applied, allowing for a nuanced understanding of the short and long-term effects of armed conflicts, food price inflation, and climate variability on malnutrition. Additionally, the study employed kernel-based regularized least squares, a sophisticated statistical technique, to further enhance the robustness of the findings. The analysis was conducted using STATA version 17. RESULTS: In the short run, armed conflicts and food price inflation exhibit positive associations with global acute malnutrition, particularly in conflict-prone areas and during inflationary periods. Moreover, climatic variables, specifically temperature and rainfall, demonstrate positive associations. It is important to note that temperature lacks a statistically significant relationship with global acute malnutrition in the short run. In the long run, armed conflicts and food price inflation maintain persistent impacts on global acute malnutrition, as confirmed by the dynamic ARDL simulations model. Furthermore, both temperature and rainfall continue to show positive associations with global acute malnutrition, but it is worth noting that temperature still exhibits a non-significant relationship. The results from kernel-based regularized least squares were consistent, further enhancing the robustness of the findings. CONCLUSIONS: Increased armed conflicts, food price inflation, temperature, and rainfall were associated with increased global acute malnutrition. Strategies such as stabilizing conflict-prone regions, diplomatic interventions, and peace-building initiatives are crucial, along with measures to control food price inflation. Implementing climate adaptation strategies is vital to counter temperature changes and fluctuating rainfall patterns, emphasizing the need for resilience-building. Policymakers and humanitarian organizations can leverage these insights to design targeted interventions, focusing on conflict resolution, food security, and climate resilience to enhance Somalia's overall nutritional well-being.

RESUMEN

OBJECTIVES: The Inflation Reduction Act (IRA), enacted in 2022, brings substantial reforms to the US healthcare system, particularly regarding Medicare. A key aspect includes the introduction of Medicare price negotiation. The objective of this commentary is to explore the implications of the IRA for US pharmaceutical companies, with a specific focus on the role of real-world evidence (RWE) in the context of Medicare reforms. METHODS: This commentary uses a qualitative analysis of the IRA's provisions related to healthcare and pharmaceutical regulation, focusing on how these reforms change the evidence requirements for pharmaceutical companies. It discusses the methodological aspects of generating and using RWE, including techniques such as target trial emulation and quantitative bias analysis methods to address biases inherent in RWE. RESULTS: This commentary highlights that the IRA introduces a unique approach to value assessment in the United States by evaluating drug value several years after launch, as opposed to at launch, similar to health technology assessments in other regions. It underscores the central role of RWE in comparing drug effectiveness across diverse clinical scenarios to improve the accuracy of real-world data comparisons. Furthermore, this article identifies key methodologies for managing the inherent biases in RWE, which are crucial for generating credible evidence for IRA price negotiations. CONCLUSIONS: This article underscores the importance of these methodologies in ensuring credible evidence for IRA price negotiations. It advocates for an integrated approach in evidence generation, positioning RWE as pivotal for informed pricing discussions in the US healthcare landscape.

RESUMEN

INTRODUCTION: Although hip arthroscopy continues to be one of the most used arthroscopic procedures, no focused, comprehensive evaluation of reimbursement trends has been conducted. The purpose of this study was to analyze the temporal Medicare reimbursement trends for hip arthroscopy procedures. METHODS: From 2011 to 2021, the Medicare Physician Fee Schedule Look-Up Tool was queried for Current Procedural Terminology (CPT) codes related to hip arthroscopy (29860 to 29863, 29914 to 29916). All monetary data were adjusted to 2021 US dollars. The compound annual growth rate and total percentage change were calculated. Mann-Kendall trend tests were used to evaluate the reimbursement trends. RESULTS: Based on the unadjusted values, a significant increase in physician fee was observed from 2011 to 2021 for CPT codes 29861 (removal of loose or foreign bodies; % change: 3.49, P = 0.03) and 29862 (chondroplasty, abrasion arthroplasty, labral resection; % change: 3.19, P = 0.03). The remaining CPT codes experienced no notable changes in reimbursement based on the unadjusted values. After adjusting for inflation, all seven of the hip arthroscopy CPT codes were observed to experience a notable decline in Medicare reimbursement. Hip arthroscopy with acetabuloplasty (CPT: 29915) and labral repair (CPT: 29916) exhibited the greatest reduction in reimbursement with a decrease in physician fee of 24.69% ( P < 0.001) and 24.64% ( P < 0.001), respectively, over the study period. DISCUSSION: Medicare reimbursement for all seven of the commonly used hip arthroscopy services did not keep up with inflation, demonstrating marked reductions from 2011 to 2021. Specifically, the inflation-adjusted reimbursements decreased between 19.23% and 24.69% between 2011 and 2021.

RESUMEN

This paper investigates the long-run and short-run relationship between money supply and inflation in Pakistan, utilizing annual data spanning from 1981 to 2021. The key objective is to assess the impact of monetary policy, specifically money supply, on inflation dynamics in the country. To achieve this, the Autoregressive Distributed Lag (ARDL) bounds testing approach is employed, which is suitable for analyzing cointegration among variables with mixed integration orders. The results reveal both short and long-run cointegration between inflation, money supply, unemployment, and interest rates. Notably, unemployment demonstrates a negative correlation with inflation, while money supply and interest rates exhibit a positive relationship. These findings underscore the importance of dedicated policy measures to manage inflation effectively. The paper concludes by recommending the establishment of a policy implementation body and collaboration between the government and the central bank to ensure financial stability and control inflation through well-calibrated monetary and fiscal policies.

RESUMEN

I apply Dawid's Meta-Empirical Assessment (MEA) methodology to the theory of cosmological inflation. I argue that applying this methodology does not currently offer a compelling case for ascribing non-empirical confirmation to cosmological inflation. In particular, I argue that despite displaying strong instances of Unexpected Explanatory Coherence (UEA), it is premature to evaluate the theory on the basis of the No Alternatives Argument (NAA). More significantly though, I argue that the theory of cosmological inflation fails to sustain a convincing Meta-Inductive Argument (MIA) because the empirical evidence and theoretical successes that it seeks to draw meta-empirical support from do not warrant a meta-inductive inference to inflation. I conclude by assessing how future developments could pave the way towards crafting a more compelling case for the non-empirical confirmation of cosmological inflation.

RESUMEN

The enduring discourse regarding the effectiveness of interest rate policy in mitigating inflation within developing economies is characterized by the interplay of structural and supply-side determinants. Moreover, extant academic literature fails to resolve the direction of causality between inflation and interest rates. Nevertheless, the prevalent adoption of interest rate-based monetary policies in numerous developing economies raises a fundamental inquiry: What motivates central banks in these nations to consistently espouse this strategy? To address this inquiry, our study leverages wavelet transformation to dissect interest rate and inflation data across a spectrum of frequency scales. This innovative methodology paves the way for a meticulous exploration of the intricate causal interplay between these pivotal macroeconomic variables for twenty-two developing economies using monthly data from 1992 to 2022. Traditional literature on causality tends to focus on short- and long-run timescales, yet our study posits that numerous uncharted time and frequency scales exist between these extremes. These intermediate scales may wield substantial influence over the causal relationship and its direction. Our research thus extends the boundaries of existing causality literature and presents fresh insights into the complexities of monetary policy in developing economies. Traditional wisdom suggests that central banks should raise interest rates to combat inflation. However, our study uncovers a contrasting reality in developing economies. It demonstrates a positive causal link between the policy rate and inflation, where an increase in the central bank's interest rates leads to an upsurge in price levels. Paradoxically, in response to escalating prices, the central bank continues to heighten the policy rate, thereby perpetuating this cyclical pattern. Given this observed positive causal relationship in developing economies, central banks must explore structural and supply-side factors to break this cycle and regain control over inflation.

RESUMEN

La Canasta Alimentaria Normativa (CAN) es un instrumento estratégico de planificación y seguimiento, que impacta el ámbito económico (fijación del salario mínimo SM y del umbral de la pobreza relativa), la seguridad alimentaria y la salud pública. El objetivo fue describir la evolución histórica de la CAN en Venezuela, contrastando su valoración económica respecto al SM durante el período 1990 ­ 2023. Tipo de estudio: Descriptivo. Se empleó la CAN del Instituto Nacional de Estadísticas/Instituto Nacional de Nutrición (INE/INN) y su comparación con la canasta del Centro de Documentación y Análisis Social de la Federación Venezolana de Maestros(CENDAS ­ FVM). Los valores mensuales de la CAN y del SM se recalcularon a dólares USA, de acuerdo a la tasa de cambio oficial. No se incluyó evaluación de la estructura interna, ni sus expresiones en términos de aporte de energía y nutrientes. Resultados: Desde 1990 hasta el año 2015, se requirieron entre1,0 y 1,8 SM y entre 0,6 y 1,7 Ingresos Mínimos Legales (IML)para acceder a la CAN. Para el año 2023 se requirieron hasta 78,3SM y 51,6 IML. El valor promedio de la canasta del CENDAS-FVM fue superior al valor de la CAN INE/INN, en una proporción de 1,7: 1. Conclusiones: la CAN resultó sensible en identificar los cambios y tendencias de su estimación económica, en el ambiente inflacionario venezolano. El uso de sus resultados está sujeta a cierto grado de discrecionalidad política. El costo de la CAN, expresa una contracción del poder de compra de los hogares venezolanos con potenciales impactos sobre la nutrición y la salud física y mental a corto y largo plazo.

RESUMEN

los modelos público-sanitarios de caráctermonopólico como el venezolano, suelen asociarse a tendencias al racionamiento de los bienes y servicios que proveen a sus usuarios, así como a la merma de la calidad de estos. Por otro lado, la provisión de dichos bienes y servicios por la vía de mecanismos de mercado, tiene ante sí, el inconveniente que supone el ambiente inflacionario de su economía, cuyo impacto en los precios limita el acceso del paciente a su consumo. El caso de la enfermedad cardiovascular ofrece algunas claves para la comprensión de este fenómeno en el medio venezolano.

Public-health models of a monopolistic nature, suchas the Venezuelan, bring with them trends in the rationing ofthe goods and services they provide to their users, as well as inthe reduction of their quality. On the other hand, the provisionof these goods and services by means of market mechanisms hasbefore it, in our environment, the enormous impediment posedby the inflationary environment of its economy, whose impacton prices limits the patient's access to consumption. The case of cardiovascular disease offers some keys to understanding thisphenomenon in the Venezuelan environment.
