Der Einfluss einer staatlichen Grundsicherung auf die Versicherungsnachfrage bei asymmetrischer Informationsverteilung

In this article, we develop a model framework in which the influence of a state assistance on insurance demand in an insurance market with imperfect information can be examined. It turned out that a state subsidy of very low level has no influence on the insurance demand at all. If the state assistance is adequately high, the individuals will prefer government assistance to market insurance. In case of adverse selection, a state assistance can have the consequence that the good risks decide not to buy any insurance while the bad risks purchase full insurance cover. The state assistance can therefore contribute to solve the problem of adverse selection. In case of moral hazard, a surprising result has been found out. The state assistance can bring the measures of loss minimizing to a standstill before the insurance can do it. The state subsidy amplifies the moral hazard behaviour and is therefore not a suitable instrument to solve problems with moral hazard.

An analysis of the opening mechanisms of Exchange Traded Fund markets

We examine the opening of Exchange Traded Fund (ETF) markets in a multimarket trading environment. We find that the opening trades on the American Stock Exchange (AMEX) are the most costly. This result is consistent with the market power hypothesis which suggests that the specialists use their informational advantage about the order imbalance at the open or take advantage of the inelastic demand at the open by imposing wider spreads. We also find that the transparent opening mechanisms of the New York Stock Exchange (NYSE) and Electronic Communication Networks (ECNs) enable them to facilitate greater price discovery at the opening and to have more efficient opening prices. This result implies that the transparency effect dominates the market power effect. Further, we find that peripheral markets do not passively free ride on information revealed through the AMEX because their opening trades contribute significantly to the price discovery process.     

Updating Poverty Maps without Panel Data: Evidence from Vietnam*

A household survey and a census can be combined to estimate a poverty map for small areas. Ideally, the survey and the census should be conducted in the same year. In several empirical applications, however, survey and census years can be different, which might make poverty estimates biased. Using data from the Vietnam Household Living Standard Survey 2002 and the 1999 Population and Housing Census, the present paper produces a 2002 poverty map for Vietnam and describes the biases when the survey and census years are not coincident. It is found that poverty estimates from the poverty mapping method taking into account the time difference between the survey and the census are quite close to survey‐based estimates, at least at the regional level.     

Service value and switching barriers: a personal values perspective

This research aims to investigate how customers, the key actors in a service relationship, perceive service value and switching barriers. The study is framed along the means-end-chain theory of personal values and theory of customer resources in the service-dominant logic. Hypotheses about the impact of personal values on customer value, switching barriers and customer loyalty were tested using structural equation modeling of survey data obtained from the health care and retail banking sectors in Vietnam. The results show that in both sectors, personal values have a significant impact on perceived process and outcome value as well as on perceived economic and relational switching barriers. Economic barriers were found to affect loyalty in the banking sector, in the same way that relational barriers affect loyalty in the health-care sector only. Loyalty in both sectors is influenced by process but not by outcome value. The implications of these findings are discussed.
