This study assesses the role of ICT in complementing private credit bureaus (PCB) and public credit registries (PCR) in reducing information asymmetry for financial access. The empirical evidence is based on Generalised Method of Moments with 53 African countries for the period 2004–2011. The following findings are established. First on financial access: (i) the marginal effects from interactions between ICT and PCR (PCB) are consistently positive (negative); (ii) net effects from interactions are negative with the higher magnitude from PCR and (iii) only thresholds corresponding to interactions between PCR and internet penetration are within range. Second, findings on financial allocation efficiency reveal positive marginal and net effects exclusively for mobile phones and PCR. Third, allocation efficiency may be constrained by increasing financial deposits. Overall, the complementarity between information offices and ICT in boosting financial access is still very limited. Policy implications are discussed with emphasis on improving the engaged complementarity and fighting surplus liquidity.  相似文献

Optimal government bond supply is examined under asymmetric information and safe asset scarcity. Corporations issue junk debt when demand for safe debt is high since uninformed investors then migrate to risky overheated debt markets. Uninformed demand stimulates informed speculation, driving debt prices toward fundamentals, encouraging pooling at high leverage. As borrower of first resort, government can issue bonds, siphoning off uninformed demand for risky corporate debt, reducing wasteful informed speculation. Government bonds eliminate pooling at high leverage or improve risk sharing in such equilibria. Optimal government bond supply is increasing in demand for safe assets and non-monotonic in marginal Q.  相似文献

This paper provides a systematic framework to determine local delivery centre (LDC) locations and service areas to reduce delivery costs and balance the allocation of parcel delivery loads to promote sustainable LDC development. Based on a case study of a parcel distribution company in Korea, this study proposes two strategies for LDC service area delineation within each terminal service boundary that either minimises the total delivery time or balances the allocation of delivery loads. This research contributes to improving cost efficiency and balancing delivery load allocations in planning LDC locations and service areas that can potentially promote the long-term mutual sustainable development of parcel distribution companies and their local delivery counterparts.  相似文献

We report on an experiment comparing compulsory and voluntary voting institutions in a voting game with common preferences. Rational choice theory predicts sharp differences in voter behavior between these two institutions. If voting is compulsory, then voters may find it rational to vote insincerely, i.e., against their private information. If voting is voluntary so that abstention is allowed, then sincere voting in accordance with a voter's private information is always rational while participation may become strategic. We find strong support for these theoretical predictions in our experimental data. Moreover, voters adapt their decisions to the voting institution in place in such a way as to make the group decision accuracy differences between the two voting institutions negligible. The latter finding may serve to rationalize the co-existence of compulsory and voluntary voting institutions in nature.  相似文献

以46家辽宁上市公司为样本,对影响董事会报告透明度因素的研究发现:股权集中度、管理层持股比例、董事会规模、独立董事比例与董事会报告透明度呈正相关关系;股权制衡度,董事长与总经理是否两职合一,审计意见类型与董事会报告透明度呈负相关关系。上市公司应该通过股票期权等方式提升管理人员的持股比例,激励他们积极治理公司,提高董事会报告信息披露的透明度;上市公司第二大股东应适度提高持股比例,防止一股独大现象;同时减少董事长与总经理两职合一,也会有助于提高董事会报告的透明度。  相似文献

Designing an effective return policy is a difficult task for retailers. A very restrictive return policy can keep logistic costs down and prevent fraudulent returns but it can also have a negative effect on consumer behavior. Two experiments explore the role of assortment-related information in moderating consumers׳ negative reactions to more restrictive product return policies. The results demonstrate that consumers will view an assortment characterized by a more restrictive return policy as attractive to the extent that the assortment supports the information processing strategy triggered by the return policy.  相似文献

Employee innovative behaviors lay the foundation for organizational innovation and are of importance to business success, especially for service firms. Although these innovative behaviors are performed at the individual level, employees still need to have frequent exchanges with others, such as customers. As there is little research investigating customer-employee exchange (CEX) and its influence on employee innovative behavior in services, this study aims to fill this gap in a hotel context. The results of a survey with 180 respondents indicate that both the solidarity and harmonization components of CEX have positive effects on employee innovative behavior, yet the information exchange between customers and employees does not significantly influence employee innovation. Also, higher level of CEX leads to higher level of perceived social psychological climate for innovation. The mediating effect of social psychological climate in the relationship between CEX and employee innovative behavior is partially supported. The findings contribute to the understanding of the role of social exchanges in facilitating employee innovative behavior and provide implications for the management of employee innovative behavior in hospitality firms.  相似文献

This paper presents a simple framework for the valuation of compound options within shadow costs of incomplete information and short sales. The shadow cost includes two components. The first component is the product of pure information cost due to imperfect knowledge and heterogeneous expectations. The second component represents the additional cost caused by the short-selling constraint. Information costs are linked to Merton's (1987. Journal of Finance 42, 510) model of capital market equilibrium with incomplete information, CAPMI. This model is extended by Wu et al. (1996. Review of Quantitative Finance and Accounting, 7, 136) who propose an incomplete-information capital market equilibrium with heterogeneous expectations and short sale restrictions, GCAPM. This model is used in our paper to provide for the first time in the literature analytic solutions for derivatives in the presence of both shadow costs of incomplete information and short sales.When deriving the compound call option formula, we consider a call option on a stock, which is itself an option on the assets of the firm. Our methodology incorporates shadow costs of incomplete information and short sales on the firm's assets as well as the effects of leverage in the capital structure. The formula can be useful in the valuation of several corporate liabilities in the presence of information uncertainty and short sales constraints about the firm and its cash flows. Our analysis can be used for the valuation of several real options.  相似文献
