Advertising a second-price auction

This study examines a symmetric private-value second-price auction model in which the seller solicits bidders at a cost, sets a reserve price, and receives a payoff which is a convex combination of revenue and welfare. The bidder’s valuations are drawn from a distribution with a decreasing hazard rate and non-decreasing virtual valuations. We find that at equilibrium the seller adopts an advertising policy which minimizes the uncertainty over the number of participants, and sets a reserve price which only depends on the distribution of valuations and the weight on revenue in the objective function. A welfare-maximizing seller is shown to advertise more than a revenue-maximizing seller, and a ceteris paribus increase in the advertising level is proved to increase the expected winner’s rent.     

Phoenix rising: Legal reforms and changes in valuations in Finland during the economic crisis

Finland experienced an extremely severe economic depression in the early 1990s. As a part of the government's crisis management policies, significant new legislation was passed that increased supervisory powers of financial market regulators and reformed bankruptcy procedures significantly decreasing the protection of creditors. We show that the introduction of these new laws resulted in positive abnormal stock returns. The new laws also lead to increases in firms’ Tobin's q, especially for more levered firms. In contrast to previous studies, our results also suggest that public supervision of financial markets fosters rather than hampers financial market development.     

准市场下我国排水权交易定价方法的研究

为解决强降水集中时期我国突出的排水权矛盾,开展排水权配置与交易的研究势在必行,而排水权交易价格问题又是排水权交易问题的关键要素。为此,在借鉴国内外有关水权交易市场和水权交易价格理论和实践的基础上,结合我国排水权交易的现状及特征,提出排水权交易价格形成的两个步骤:一是利用全成本定价法测算排水权交易的基础价格;二是在基础价格之上,研究排水权市场化定价方式。最后,构建出"成本+竞价"的排水权交易定价的综合模式,该模式综合协商定价、招投标定价和拍卖竞价于一体,充分发挥了3种交易方式的各自优势。研究结果有利于推动排水权交易市场的构建,为完善我国排水权交易管理制度提供参考。     

Gains,Losses, and the US-EPA <Emphasis Type="Italic">Economic Analyses Guidelines</Emphasis>: A Hazardous Product?

While offering many useful suggestions to improve economic analyses, the Guidelines take no account of widely reported behavioural economics research findings. Foregoing the opportunities to improve valuations and other analyses offered by this evidence is likely to lead to inappropriate assessments and consequent distortions of damage estimates, policy and regulatory design.

Sticky Valuations,Aggregation Effects,and Property Indices

Previous studies on real estate smoothing have generally focused on the second moment of returns for individual properties. Although this body of research has developed plausible reasons for explaining the observed lower risk associated with real estate, no explanation has, however, been offered to account for the large difference in serial correlation at the individual property level compared with the index level. This article addresses this issue and also offers an explanation for the difference in serial correlation observed with different frequency real estate indices. Employing the framework developed by Holbrook Working (1960), we argue that the high levels of serial correlation typically observed in real estate indices results from a combination of random and sticky appraisals that induce cross-correlations between the component returns. Using the concept of sticky values we question the results of Lai and Wang (1998) in which they argue that the variance of appraisal-based returns should always be greater than true returns. We argue that a pragmatic conclusion regarding volatility should be conditioned on the underlying stochastic processes. We draw a distinction between serial cross-sectional and temporal sticky appraisal processes that influence smoothing at the index and individual property levels. Our results indicate that smoothing does not appear to be a serious issue at the individual property level. However, when different appraisal processes are aggregated into an index the underlying cross-correlation between those processes can induce high levels of smoothing.     

Measuring Passive Use Value: Pledges, Donations and CV Responses in Connection with an Important Natural Resource

This paper examines monetary valuations of lost passive-use benefits associated with damage to a unique environmental resource – a national park, elicited through contingent valuation, and compares them with actual donations to the same end, where the latter are interpreted as a quasi-market expression of willingness to pay for non-market resource services. The relationships between the two valuation approaches were investigated in the specific context of an environmental episode which damaged a unique natural endowment, Israel's Carmel National Park. The empirical analysis is based on data from two sample surveys; one sample was drawn from the population of people who either pledged or pledged and donated during a fund-raising campaign following the episode, with the proceeds dedicated to rehabilitation or prevention of future episodes; the second sample was drawn from the general population of the country. The results cannot be interpreted as providing unqualified support for the reliability of contingent valuation as a means for obtaining passive use values.     

Monetary valuations of university course delivery: the case for face-to-face learning activities in accounting education

Student preferences for delivery options were obtained within a monetary framework by asking students to purchase their ideal course structure. Results show that accounting students prefer to spend more on tutorials but purchase less lecture time; the difference due to the higher cost of tutorials compared to lectures. Face-to-face classes were preferred to web-based materials. Within lectures and tutorials students prefer more time devoted to teacher-centred activities than student-centred activities. Monetary valuations, where students must take into account the cost of delivery as well as effectiveness, provide insights for teaching staff and administrators, who need to simultaneously enhance teaching and learning, satisfy student preferences and operate with limited resources. Online and/or student-centred learning may not be compatible with preferences of accounting students. Teachers need to balance calls to change educational delivery and learning activities with preferences of accounting students, or ensure they educate students on why non-preferred approaches are undertaken.     

The value of rents and the likelihood of conflicts

This paper extends the prey–predator model of Grossman and Kim (J Political Econ 103:1275–1288, 1995) to analyze the relation between the value of a contested rent and the emergence of conflict. We show that an increase in the value of the rent makes a conflict equilibrium more likely. We also analyze the case where the valuation of the rent is different for the two players. We find, for example, that a conflict equilibrium may occur even though the predator has an important disadvantage in warfare. That is when his valuation of the rent is sufficiently high compared to that of the prey.

Auctions with endogenous valuations: the snowball effect revisited

Summary. This paper looks at the determination of ownership of capacity when there are two ex-ante symmetric agents bidding for many units of capacity which are sold sequentially. It is shown that convexity of payoffs in the final stage of the game is sufficient to ensure monopolization of capacity, but that increasing returns to scale are not sufficient to ensure monopolization.
