医院产权制度改革成为“重头戏”

国有医院产权制度改革已悄然启动,并且成为当前产权制度改革的重点。医院改革的总体思路是保一部分,放一大批,政府和市场同时发挥资源配置作用。针对改制中的“难点”,沪、江、浙部分先行改制的医院采取了相应的解决办法,但政府也应该完善相关政策,推进和规范医院的产权制度改革。     

Influencia de los sistemas de información en los resultados organizacionales

Over the last years, information systems (IS) have constituted the main focus of research in the business organization literature. This has created the need to identify their entrepreneurial value. The paper presents a theory-based model that was developed to assess the degree of IS success in SMEs. The aim of the proposed model is to determine the influence of IS on organizational performance. To achieve this aim, the Partial Least Square statistical technique is used to analyze data from 133 questionnaires administered to businesses across the state of Tamaulipas, Mexico. The results show that those enterprises that are more concerned with the improvement of the systems’ quality, information quality and the informatics service enhance the organizational outcomes. The present study contributes to the body of literature on the assessment of IS success in the context of an emerging country. In particular, the study provides a thorough assessment of the IS effectiveness and their impact on organizational performance.     

Efficient estimation of semiparametric conditional moment models with possibly nonsmooth residuals

This paper considers semiparametric efficient estimation of conditional moment models with possibly nonsmooth residuals in unknown parametric components (θ) and unknown functions (h) of endogenous variables. We show that: (1) the penalized sieve minimum distance (PSMD) estimator can simultaneously achieve root-n asymptotic normality of and nonparametric optimal convergence rate of , allowing for noncompact function parameter spaces; (2) a simple weighted bootstrap procedure consistently estimates the limiting distribution of the PSMD ; (3) the semiparametric efficiency bound formula of [Ai, C., Chen, X., 2003. Efficient estimation of models with conditional moment restrictions containing unknown functions. Econometrica, 71, 1795–1843] remains valid for conditional models with nonsmooth residuals, and the optimally weighted PSMD estimator achieves the bound; (4) the centered, profiled optimally weighted PSMD criterion is asymptotically chi-square distributed. We illustrate our theories using a partially linear quantile instrumental variables (IV) regression, a Monte Carlo study, and an empirical estimation of the shape-invariant quantile IV Engel curves.     

The Trans-Political Nature of Southwest China’s Energy Conduit,Yunnan Province

Transboundary flows of energy across Yunnan Province in China and to Southeast Asian states provide insight into the changing nature of borders and border areas. Rather than monolithic symbols of state sovereignty, China’s southwest borders in Yunnan can be more accurately characterised as zones of connectivity and exchange, serving a range of local, national and regional objectives. Energy production and distribution in and across Yunnan can be understood as functioning in a set of dynamic transnational processes that serve as economic and political bridges – increasing interaction and deepening regional integration – while also working to mitigate risk to China’s energy demands. In this article, energy projects in Yunnan and Southeast Asia demonstrate the ways border regions can respond to increasing globalisation, simultaneously strengthening national energy security while promoting regional interconnection and diplomacy. Thus, connections to and through a once peripheral region present an apparent contradiction: once rigid territorial borders are increasingly characterised by transboundary infrastructure development and exchanges of energy, capital and diplomacy, while promoting broader, diversified national energy security objectives – essentially strengthening national security through transnational energy projects. This article investigates how energy development works to shape Yunnan’s role as an “energy conduit,” while advancing both transnational and national geopolitical objectives, and thus, suggesting that these projects can be understood as trans-political in nature.     

Estimation and model selection of semiparametric multivariate survival functions under general censorship

We study estimation and model selection of semiparametric models of multivariate survival functions for censored data, which are characterized by possibly misspecified parametric copulas and nonparametric marginal survivals. We obtain the consistency and root-n$n$ asymptotic normality of a two-step copula estimator to the pseudo-true copula parameter value according to KLIC, and provide a simple consistent estimator of its asymptotic variance, allowing for a first-step nonparametric estimation of the marginal survivals. We establish the asymptotic distribution of the penalized pseudo-likelihood ratio statistic for comparing multiple semiparametric multivariate survival functions subject to copula misspecification and general censorship. An empirical application is provided.     

Corporate Credit Spreads and the Sovereign Ceiling in Latin America

We exploit a panel of 72 US dollar-denominated bonds issued by Latin American publicly listed firms between 1996 and 2004, a period of regional financial crises, to answer the following three questions: (1) Is sovereign risk a statistically and economically significant determinant of the corporate credit spread, controlling for firm- and bond-specific characteristics? (2) If yes, do market participants apply the sovereign ceiling rule adopted by rating agencies in the pricing of our bond market data? And (3) how do market views compare with the rating agencies ceiling policy for each corporate bond? We find strong evidence of an economically and statistically significant effect of sovereign risk on corporate spreads across different panel econometric specifications and bonds. Moreover, markets do not apply the ceiling rule in 77–90% of the bonds we sample and these findings are consistent with rating agencies’ policies toward the latter for about 50% of the firms. These results are robust to the inclusion of firm- and bond-specific variables derived from the structural approach to credit risk and to the business cycle in each country.     

RETROSPECTIVE VOTING AND PARTY POLARIZATION

We provide a new and favorable perspective on voter naiveté and party polarization. We contrast sophisticated (Nash) versus retrospective voting in a model where two parties commit to policies. Retrospective voters do not understand the mapping between states and outcomes induced by a policy; instead, they simply vote for the party that delivers the highest observed performance, as determined in equilibrium. We show that parties have an incentive to polarize under retrospective, compared to Nash, voting. Moreover, this polarization often results in higher welfare due to a better match between policies and fundamentals.
