金融中介及关系银行——基于广东外资企业银行融资数据的研究

本文根据外资银行和国有商业银行向在中国境内的外资企业提供的外币贷款和人民币贷款的数据 ,对金融中介及关系银行进行了实证研究。我们的主要结论有两点 :第一 ,企业与银行建立起来的金融业务关系越长久 ,那么其所获得的外币贷款利率就越低。这是对金融中介理论的支持。另外 ,外资控股、第三方担保等因素 ,也具有降低外币贷款利率的效应。第二 ,人民币贷款的利率随着外资企业与更多的银行建立和保持合作关系而降低。人民币贷款主要是由我国商业银行提供。如果商业银行间的竞争仅仅是用来作为信贷定价的主要决定因素 ,而不是用来推进金融创新 ,提供高质量的金融产品和服务 ,那么这将会损害我国商业银行的获利能力并进而影响金融系统的健康发展。     

General training by firms, apprentice contracts, and public policy

Workers will not pay for general on-the-job training if contracts are not enforceable. Firms may if there are mobility frictions. Private information about worker productivities, however, prevents workers who quit receiving their marginal products elsewhere. Their new employers then receive external benefits from their training. In this paper, training firms increase profits by offering apprenticeships which commit firms to high wages for those trainees retained on completion. At these high wages, only good workers are retained. This signals their productivity and reduces the external benefits if they subsequently quit. Regulation of apprenticeship length (a historically important feature) enhances efficiency. Appropriate subsidies enhance it further.     

Taxation and household portfolio composition: US evidence from the 1980s and 1990s

This paper explores the relationship between household marginal income tax rates, the set of financial assets that households own, and the portfolio shares accounted for by each of these assets. It analyzes data from the 1983, 1989, 1992, 1995, and 1998 Surveys of Consumer Finances and develops a new algorithm for imputing federal marginal tax rates to households in these surveys. The empirical findings suggest that marginal tax rates have important effects on asset allocation decisions. The probability that a household owns tax-advantaged assets, such as tax-exempt bonds or assets held in tax-deferred accounts, is positively related to its tax rate on ordinary income. In addition, the portfolio share invested in corporate stock, which is taxed less heavily than interest bearing assets, is increasing in the household’s ordinary income tax rate. Holdings of heavily taxed assets, such as interest-bearing accounts, decline as a share of wealth as a household’s marginal tax rate increases.     

Strategic niche management: towards a policy tool for sustainable development

Strategic niche management (SNM) is a recently developed approach that could help induce a broad socio-technical transition towards more sustainable development. It is designed to facilitate the introduction and diffusion of new sustainable technologies through protected societal experiments in fields such wind energy, biogas, public transport systems, electric vehicle transport and eco-friendly food production. A major challenge in SNM concerns the processes by which such experiments can evolve into viable market niches and ultimately contribute to a broader shift towards sustainable development. This paper sheds more light on this issue by systematically consolidating the main SNM studies, and by bringing in new insights from the literature that is in some sense complementary to SNM. These are studies on the development and commercialisation of radical innovations in large companies, and literature about infant industry protection and broader industrialisation processes in developing countries. A number of suggestions for implementing SNM are given.     

Second chance offers versus sequential auctions: theory and behavior

Second chance offers in online marketplaces involve a seller conducting an auction for a single object and then using information from the auction to offer a losing bidder a take-it-or-leave-it price for another unit. We theoretically and experimentally investigate this practice and compare it to two sequential auctions. We show that the equilibrium bidding strategy in the second chance offer mechanism only exists in mixed strategies, and we observe that this mechanism generates more profit for the auctioneer than two sequential auctions. We also observe virtually no rejections of profitable offers in the ultimatum bargaining stage.      

Where health care dollars are spent when pediatric palliative care is provided

Although pediatric palliative care has become more accessible over the past decade, little research has been performed that focuses on the financial impact of providing palliative care in an inpatient hospital setting. Using a case-controlled methodology, health care costs and the distribution of these costs were compared between children who received palliative care to those who did not. In comparing children who received palliative services to case controls, the similarities are striking, and the differences may have clinical significance. Children receiving care coordinated by the palliative care program underwent fewer radiology procedures and received greater assistance from pharmacologic services. This reflects greater attention and interventions provided to treat pain and provide comfort.     

SCALE ECONOMIES OF THE FRANCHISED BUSES AND FERRIES OF HONG KONG, 1948–1998

The privatization of state transport operators has been driven by empirical discoveries in transport economic research of the constant or even diseconomies of scale of these operators. With reference to public records and official statistics, this paper is an initial attempt to examine the scale economies of and output relationship between major bus and ferry operators in Hong Kong during the period 1948–1998. The two franchised bus and two franchised ferry companies each experienced unique scale effects during different periods and correlated with each other in terms of production. The paper will also discuss the possible reasons for this phenomenon and policy concerns related to this finding.     

Locating farmers’ markets with an incorporation of spatio-temporal variation

The recent drive among consumers to purchase fresh, healthy and environmentally friendly food has brought about a renewed interest in farmers’ markets. However, ensuring the success of a farmers’ market is not an easy task. Unlike general grocery stores, farmers’ markets often have very limited hours of service and are distributed sparsely in space. Both spatial and temporal constraints that people experience in their daily lives limit their accessibility to a farmers’ market. This research incorporates such constraints in the service provision planning of farmers’ markets. In particular, two models are proposed to select locations and the associated service schedules for a fixed number of farmers’ markets. A case study is conducted in Tucson, Arizona to demonstrate the merits of the new approach.
