trends in Centralization of cancer surgery
Annals of Surgical Oncology, 2010Co-Authors: Karyn B Stitzenberg, Neal J MeropolAbstract:Background The association between procedure volume and clinical outcomes has led many to advocate Centralization of cancer procedures at high-volume centers (HVCs). Regional studies show practice patterns changing with increasing Centralization of esophageal and pancreatic procedures at HVCs but little change for colorectal procedures. We hypothesize that similar trends are occurring nationwide.

managing supply uncertainty under supply chain cournot competition
European Journal of Operational Research, 2015Co-Authors: Yaner Fang, Biying ShouAbstract:We study the Cournot competition between two supply chains that are subject to supply uncertainty. Each supply chain consists of a retailer and an exclusive supplier which has random yield. We examine how the levels of supply uncertainty and competition intensity affect the equilibrium decisions of ordering quantity, contract offering, and Centralization choice. We show that a retailer should order more if its competing retailer’s supply becomes less reliable or if its own supply becomes more reliable. A supply chain with reliable supply can take great advantage of the high supply risk of its competing chain. Furthermore, for decentralized chains we characterize the optimal wholesale price contracts with linear penalty, under different supply risks and competition scenarios. Finally, we show that supply chain Centralization is a dominant strategy, and it always makes the customers better off. Nevertheless, if the supply risk is low and the chain competition is intensive, Centralization could actually decrease the supply chain profit, compared with the case where both chains do not choose Centralization. This results in a prisoner’s dilemma. On the other hand, if the supply risk is high and/or the competition level is low, Centralization always increases the supply chain profit. The desirability of supply chain Centralization is enhanced by high supply uncertainty or low chain competition.

Centralization, Fiscal Federalism, and Private School Attendance
International Economic Review, 2003Co-Authors: Thomas J. NechybaAbstract:A CGE model is used to analyze the impact of public school financing on private school attendance. The common perception that public school finance Centralization will necessarily lead to greater private school attendance is not correct in such a model—even when that Centralization involves an extreme equalization as in California. Furthermore, if Centralization is less dramatic (as in most states), declines in private school attendance are even more pronounced. This weakens the speculation that low exit rates to private schools in centralizing states imply that general public school quality does not drop as a result of such Centralization.

Centralization, Fiscal Federalism and Private School Attendance
National Bureau of Economic Research, 2001Co-Authors: Thomas J. NechybaAbstract:This paper uses a computational general equilibrium model to analyze the impact of public school finance regimes on rates of private school attendance. It is shown that, when viewed in such a general equilibrium context, state intervention in locally financed systems can have somewhat unexpected and counterintuitive effects on the level of private school attendance. In particular, the common perception that Centralization of public school finance will necessarily lead to greater private school attendance is no longer correct when general equilibrium forces are taken into account even when that Centralization involves an extreme equalization of the kind observed in California. Furthermore, if Centralization occurs through less dramatic means that allow for some remaining discretion on the part of local districts, declines in private school attendance become much more unambiguous and pronounced. These results then weaken the speculation that low exit rates to private schools in centralizing states imply that general public school quality does not drop as a result of such Centralization.

on the determinants of fiscal Centralization theory and evidence
Journal of Public Economics, 1999Co-Authors: Ugo PanizzaAbstract:Abstract This paper presents a simple model that unifies most of the results of the literature on fiscal federalism. The model describes an economy characterized by two levels of government, one public good, and a private good. The predictions of the model are tested by using a new set of measures of fiscal Centralization. The main findings are that country size, income per capita, ethnic fractionalization, and level of democracy are negatively correlated with the degree of fiscal Centralization. The model is tested using OLS, Tobit, and semi-parametric estimators. The paper also shows that the variables included in the regression are helpful in the prediction of changes in the level of Centralization.

on the determinants of fiscal Centralization theory and evidence
Social Science Research Network, 1997Co-Authors: Ugo PanizzaAbstract:This paper presents a simple positive model that unifies most of the results of the normative literature on fiscal federalism. The model describes an economy characterized by two levels of government, one public good, and a private good. The predictions of the model are tested by using a new set of measures of fiscal Centralization. The main findings are that country size, income per capita, ethnic fractionalization, and level of democracy are negatively correlated with the degree of fiscal Centralization.
