Capitation fees are considered to be an option for a change in funding principles for statutory health care insurance. This paper discusses several models of capitation fees either to be introduced for a part of the population or for all citizens. It analyses the impact of a change in financing health care on the labour market. Therefore microeconomic theory and a QUERU-model is applied. It also considers the issue of presently co-insured dependents. 相似文献

Assessing the Reliability of Self‐reported Income Information in Informal Small Business Lending through a Bogus Pipeline Experiment 下载免费PDF全文
Ulf Römer Oliver Mußhoff Ron Weber Calum G. Turvey 《Journal of Agricultural Economics》2018,69(3):726-738
Coping with asymmetric information plays a major role in successful small business lending. Our purpose is to determine if small business applicants report their income information correctly when requesting a loan. We use a randomised controlled trial bogus pipeline experiment, established during a typical cash‐flow analysis of a bank for small businesses in the Philippines. The bogus pipeline approach is commonly applied in social science and aims to increase the rate of truth telling by informing participants that answers will be verified by a lie detector. The experimental data, which include 243 observations of credit clients that are mainly from the agricultural and food value chain, served to identify asymmetric information. Additionally, debtors’ repayment behaviour for approved loans was observed by the bank. Our results indicate that loan applicants of the treatment group report lower incomes, an effect which is most pronounced in lower income quantile. Our analyses also reveal higher loan delinquencies in the control group. 相似文献

There is increased interest in greater localization of food supply chains but little evidence about the effects of localization on supply-chain costs. Assessing these effects is complex in multiple-product, multi-process supply chains such as the dairy industry. In this study, we develop a spatially-disaggregated transshipment model for the US dairy sector that minimizes total supply-chain costs, including assembly, processing, interplant transportation and final product distribution. We employ the cost-minimizing solution as benchmark to compare alternative scenarios of increased supply chain localization. Our results indicate: (1) short-run limits to increased localization, (2) modest impacts on overall supply-chain costs, and (3) large cost re-allocations across supply chain segments, regions and products. We find that increased localization reduces assembly costs while increase processing and distribution costs. Cost increases are larger in regions with smaller raw milk supplies and during the season when less raw milk is produced. Minimizing distances traveled by all dairy products results in tradeoffs across products in terms of cost and distance traveled. The relationship between increased localization and costs appears to be nonlinear. 相似文献

Co-monotonicity of optimal investments and the design of structured financial products 总被引:1,自引:0,他引:1
Marc Oliver Rieger 《Finance and Stochastics》2011,15(1):27-55
We prove that, under very weak conditions, optimal financial products on complete markets are co-monotone with the reversed state price density. Optimality is meant in the sense of the maximization of an arbitrary preference model, e.g., expected utility theory or prospect theory. The proof is based on a result from transport theory. We apply the general result to specific situations, in particular the case of a market described by the Capital Asset Pricing Model or the Black–Scholes model, where we derive a generalization of the two-fund-separation theorem and give an extension to APT factor models and structured products with several underlyings. We use our results to derive a new approach to optimization in wealth management, based on a direct optimization of the return distribution of the portfolio. In particular, we show that optimal products can (essentially) be written as monotonic functions of the market return. We provide existence and nonexistence results for optimal products in this framework. Finally we apply our results to the study of bonus certificates, show that they are not optimal, and construct a cheaper product yielding the same return distribution. 相似文献

An Evolutionary Approach to Financial Innovation 总被引:6,自引:0,他引:6
The purpose of this paper is to explain why some markets for financial products take off while others vanish as soon as they have emerged. To this end, we model an infinite sequence of CAPM-economies in which financial products can be used for insurance purposes. Agents' participation in these financial products, however, is restricted. Consecutive stage economies are linked by a mapping ('transition function") which determines the next period's participation structure from the preceding period's participation. The transition function generates a dynamic process of market participation which is driven by the percentage of informed traders and the rate at which a new asset is adopted. We then analyse the evolutionary stability of stationary equilibria. In accordance with the empirical literature on financial innovation, it is obtained that the success of a financial innovation, a mutation, depends on a sufficiently high trading volume, marketing, and new and differentiated hedging opportunities. In particular, a set of complete markets forming a stationary equilibrium is robust with respect to any further financial innovation while this is not necessarily true for a set of incomplete markets.
"There is no generally accepted theory of financial innovation, but some broad generalizations of the innovation process are possible. What matters is not the invention of a financial product or process (which is often obscure) but its diffusion through the market environment".

In times of continuous change, companies need to adjust their business processes to gain sustainable competitive advantage.
Resulting changes in the company’s IT currently require the involvement of developers from departments that are mostly not
aligned with the business. These changes often result in high transaction and labor costs. The article presents a platform-based
method to adjust business processes with the aim of increasing both efficiency and flexibility compared to current approaches.
The core of our work is an evaluation against traditional component-based software development using a sound simulation model.
Three real-world scenarios of business process change show that – despite a slight increase in transaction costs – our suggested
method decreases labor costs while increasing operational flexibility. 相似文献

Die Eurozone ist vor allem durch die gef?hrdete Kreditwürdigkeit Griechenlands in eine schwere Krise geraten. Jetzt zeigt
sich, dass jede W?hrungsunion ein Konstruktionsproblem hat. Die Mitgliedstaaten müssen auf die Autonomie in der Geldpolitik
verzichten und ohne die Instrumente der Geld- und Wechselkurspolitik ihre internationale Wettbewerbsf?higkeit bewahren. 相似文献

The increasing popularity of socially responsible investment among individual investors throughout Europe reveals the need for a framework that allows the comparison of socially responsible retail markets in different European countries. This article proposes such a framework, containing 16 different characteristics of socially responsible retail markets describing the size, institutionalization and nature of this market and correcting for differences in the size of countries and financial markets. When this framework was applied to the Dutch and Belgian socially responsible retail markets, differences were found with respect to the nature of both markets (specifically the use of non‐financial criteria, the asset allocation, the number of solidarity funds and investors' preferences for socially responsible savings products). Similarities were found with respect to the (absolute and relative) size and the degree of institutionalization of the socially responsible retail markets. 相似文献

This paper explores the nature of competitive assets that are based on control of part of a market's infrastructure using a case study of the U.K. frozen food market. Following an argument due to Stigler, the thesis of the paper is that such assets are inherently transitory, and that positions of market leadership based on them tend to erode. This argument is consistent with the experiences of Birds Eye during the post-War period. 相似文献

In this paper, we examine the usefulness of expected rates of return (ERR) for public pension plans. Specifically, we test the correlation between the expected rate of return on plan assets and asset allocation. We also examine the predictive power of ERR on the actual returns of the pension assets. We find that the correlation between expected return and the percentage of assets that are equity securities is relatively weak. Further, we find that the percentage of assets that are equity securities is a much better predictor of actual returns than the disclosed expected return in public pension plans. These results provide evidence to support SFAS No. 87 , which requires the disclosure of plan assets and against recently promulgated SFAS No. 132 , which eliminates this disclosure requirement. The evidence also supports GASB 25'sStatement of Net Plan Assets . 相似文献
