Efficiency effects of cross-border medical demand

There is a growing interest in cross-border medical care and its comparative advantages. In addition, medical care can be defined as a local assurance good. Little research is being carried out in this field. This paper discusses the individual considerations for medical treatment offered at home and abroad within a micro-economical framework. Specific assumptions as mistrust, monetary and non-monetary transaction-costs, a price and cost gradient, illness severity as well as a lump-sum insurance are discussed. We show that a demand abroad can be utility maximizing, however, only second best. There are inefficiencies in the dimensions of ex-post demand and income risk either on the side of gross-income or of costs. Furthermore, the foreign demand is restricted for low health stages driven by mistrust and restrictions in quality. Higher stages are more capable if fixed costs are low. To demand abroad the marginal treatment costs abroad must fall short of a threshold level. Finally, an out-of-pocket payment can reduce the moral hazard when treatment takes place abroad. --cross-border medical care,health tourism,efficiency,patient migration,trust

International Business Cycle Accounting

In this paper, I extend the business cycle accounting method a la Chari, Kehoe and McGrattan (2007) to a two-country international business cycle model and quantify the effect of the disturbances in relevant markets on the business cycle correlation between Japan and the US over the 1980-2008 period. I find that disturbances in the labor market and production efficiency are important in accounting for the recent increase in the cross-country output correlation. Financial globalization can be the cause of the recent increase in cross-country output correlation if it operated through an increase in the cross-country correlation of disturbances in the labor market and production efficiency, not in the domestic or international capital markets

Measurement of environmental efficiency and productivity: A cross country analysis.

This paper measures environmental efficiency (EE) and environmental productivity (EP) and analyses differences in these across countries. It explores the macroeconomic factors that could explain these differences and whether these differences can be explained by income levels and by the degree of openness in these countries. The EE index is found to be almost steady over the period 1971-92 for the annex-I countries, while its value is declining for non-annex-I countries over this period. The EP index increased over this period in both groups of countries. In the annex-I countries, EE exhibits an inverted `U' shape with respect to per capita income while it is `U' shaped for the non-annex-I countries. This study also finds that while the EP index increases with income in annex-I countries it is decreasing in the non-annex-I countries. The degree of openness has a significant negative impact on EE and EP in both groups of countries.Environmental efficiency ; Environmental productivity ; Distance function ; Per capita income ; Openness

The Relative Efficiency of Educational Systems: A Cross Country Prescriptive Analysis

How does a country achieve the most efficient education system possible? We examine the efficiency of educational systems across the world using internationally comparable performance of secondary school pupils. We use OECD aggregate panel data on 39 countries across 17 years to model the most efficient combination of teacher salaries, class size and capital resources to secure the maximum level of students’ achievement. In the face of constrained education budgets prescriptive policy evaluations are provided to suggest how countries could make a significant improvement to their educational outcomes by adjusting their educational resource inputs. We also ask if there is a trade-off between the efficiency and equity of educational provision.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

High Efficiency Cross-Coupled Charge Pump Circuit with Four-Clock Signals

© Allerton Press, Inc. 2018A fully integrated cross-coupled charge pump circuit for boosting dc-to-dc converter applications with four-clock signals has been proposed. With the new clock scheme, this charge pump eliminates all of the reversion power loss and reduces the ripple voltage. In addition, the largest voltage differences between the terminals of all transistors do not exceed the power supply voltage for solving the gate-oxide overstress problem in the conventional charge pump circuits and enhancing the reliability. This proposed charge pump circuit does not require any extra level shifter; therefore, the power efficiency is increased. The proposed charge pump circuit has been simulated using Spectre in the TSMC 0.18 μm CMOS process. The simulation results show that the maximum voltage conversion efficiency of the new 3-stage cross-coupled circuit with an input voltage of 1.5Vis 99.8%. According to the comparison results of the conventional pump and the enhanced charge pump proposed, the output ripple voltage has been significantly reduced.Peer reviewe
