Summary. I show that aggregate-taking behavior is often evolutionarily stable for finite population in symmetric games in which payoff
depends only on own strategy and an aggregate. I provide economic examples exhibiting this phenomenon.

This paper presents theoretical work linking money demand to the perceptions of households about the risk that domestic currency
may become inconvertible or that it may be devalued. An empirical investigation of the size of this effect is carried out
using monthly data for Korea to estimate an augmented demand-for-money equation. It is found that the fear of inconvertibility
arising from the 1997 Korean currency crisis may have caused broad money demand to fall by 4–5% points,equivalent to the loss
of reserves of $6–7.5 billion (or about 30% of reserves as measured at end-November 1997).
This is a revised version of IMF Working paper WP/2001/210; it was written while Professor Black was Senior Policy Advisor
at the IMF Institute and Christofides and Mourmouras were staff members in the IMF’s Policy Development and Review Department.
The views expressed are those of the authors and should not be attributed to the IMF, its Executive Board, or its management.

approach by Dr. Rino Effendi for Indonesia and Angana Banerji for Russia 相似文献

This paper provides new evidence on the impact of electronic trading on brokerage commissions by investigating a sample period that covers the period of transition from floor to electronic trading on the Sydney Futures Exchange. After controlling for liquidity, volatility and broker identity, the introduction of electronic trading remains to be associated with lower brokerage commissions relative to floor markets. The study also provides new evidence on brokerage commissions in futures markets finding that commission fees charged on futures trades average 0.002% of transaction value. This is up to 120 times smaller than the magnitude of brokerage fees charged in stock markets, and considerably lower than the magnitude of brokerage fees assumed for futures markets in previous research. Consistent with existing studies based on stock markets, commissions charged per contract decrease with order size reflecting economies of scale in the provision of brokerage services in futures markets. Commission rates are positively related to bid-ask spreads and price volatility, which proxy for the probability of execution error costs and execution difficulty, respectively. Finally, the identity of the broker is found to be a significant determinant of commissions reflecting different pricing schedules across brokers. 相似文献

In this article, we define a new construct for urban economic and investment analysis, which revisits the conventional wisdom that investment in real estate development is riskier than investment in stabilized property assets. This new construct, referred as a “development asset value index” (DAVI), is a value index for newly developed properties (only) in a given geographical property market. It tracks longitudinal changes in the highest and best use (HBU) value of locations, and it reveals developer and landowner behavior taking advantage of the optionality inherent in land ownership. In particular, the DAVI reflects developers' use of flexibility in the exercise of the call option to (re)develop the property to any legal use and density. We empirically estimate a DAVI for commercial property (i.e., central locations) and compare it with a corresponding traditional transaction‐price‐based property asset price index (PAPI) corrected for depreciation. We believe that the difference primarily reflects the realized value of flexibility in land development. We find that the DAVIs display greater value growth and are smoother over time and less cyclical than their corresponding PAPIs for the same locations. This suggests that developers successfully use flexibility, and that development may be riskier than stabilized property investment due primarily only to leverage effects (construction costs). Practical implications are also discussed. 相似文献

This article examines the importance of family, gender and place to the intergenerational transmission of trade union membership. Using data from the British Household Panel Survey, we show that union membership among parents influences the union joining behaviour of young workers. These effects are particularly apparent among daughters and where both parents are members of unions. The effects of parental membership are also stronger among those born in areas characterized by relatively high levels of union density. Parental effects are therefore important to our understanding of the persistence of regional variations in levels of trade union membership. 相似文献

This study empirically examines the impact of changes in substantial shareholdings ahead of 450 Australian takeover offers between the years 2000 and 2009. Previous studies have attributed a significant proportion of the price run‐up effect in takeover targets to insider‐trading behaviour. This study examines the contribution of a broad range of public information sources that are known to typically generate market anticipation, including the acquisition of toeholds ahead of takeover announcements. Our findings show no significant pre‐bid run‐up for takeover targets after considering these sources. We conclude from these results that previous findings attributing pre‐bid share price run‐up to illegal insider trading may overstate the existence of such conduct. 相似文献

We describe an ambiguity hedging problem in Ellsberg experiments, where combinations of individually ambiguous bets eliminate aggregate ambiguity, and which may yield incorrect classifications of ambiguity averse subjects. We propose a new classification consistent with this hedging possibility. 相似文献

Compassionate care within mental health services is often taken for granted as something that can be made visible and authentic. However, recent government reports and policy suggest that we are far from providing compassionate care and may be more focused upon risk and surveillance. This paper will discuss the visibility of compassionate care and explore outcomes that consumers and practitioners could measure in practice. Separating the fact from fiction within compassionate care will make authentic involvement practices more visible and open to discussion around consumer collaboration. In a qualitative analysis of a small study with mental health consumers, compassion was found to be a major factor in whether consumers became more involved in their own health care. Demonstrating compassionate care may therefore also demonstrate consumer participation and engagement. This paper will argue that compassionate care can be observed in the relationships between practitioners and consumers that are collaborative and use presence and persistence as methods of practice. Emancipatory practices can be made more visible in mental health care in order to make compassion measurable and to encourage consumer participation and engagement. 相似文献
