This research involved developing an optimal stock investment decision strategy which offers minimum risk to the potential investor for counters listed on the Zimbabwe Stock Exchange. Three counters were compared namely Econet Wireless, Delta and Old Mutual. The first phase of the project...

Ein grundlegendes Ergebnis der Auktionstheorie besagt, dass der Preisverlauf einer sequentiellen Auktion unter üblichen IPV-Annahmen konstant ist und unter Zugrundelegung affiliierter Bewertungen sogar ansteigt. Empirische Arbeiten beobachteten jedoch in der Praxis auf unterschiedlichsten...

We study the interplay of inequality and trust in a dynamic game, in which trust increases efficiency and thus allows higher growth of the experimental economy in the future. We find that trust is initially high in a treatment starting with equal endowments, but decreases over time. In a...

In second price internet auctions with a fixed end time, such as those on eBay, many bidders snipe , i.e., they submit their bids in the closing minutes or seconds of an auction. Late bids of this sort are much less frequent in auctions that are automatically extended if a bid is submitted very...

This paper reviews and addresses a variety of issues relating to inclusive fitness. The main question is: are there limits to the generality of inclusive fitness, and if so, what are the perimeters of the domain within which inclusive fitness works? This question is addressed using two well...

This paper considers the e effcts of a two-period interaction on the decision of a principal to delegate authority to a potentially biased but better informed agent. Compared to the (repeated) one-period case, the agent's first period actions may also signal his type which in turn impacts wages...

We study price dynamics for computer components sold on a price-comparison website. Our fine-grained data — a year of hourly price data for scores of rival retailers — allow us to estimate a dynamic model of competition, backing out structural estimates of managerial frictions. The estimated...

We analyze the quantitative asset-pricing implications of peers' strategic rivalry by embedding oligopolistic competition within an endowment economy. Rivalry intensity increases endogenously as the discount rate rises or expected growth declines, because peers care less about future...

The first-price auction model has been intensively studied in the econometric literature. Probably one of the best well-known papers in this field is the one by Guerre et al. (2000) where the authors show the nonparametric identification of the distribution of the private values within the...
