In this paper I hypothesize that the well documented positive mean excess stock return earned by parent firms when they announce they are carving out stock in a subsidiary is due to noise traders who optimistically misinterpret a carve-out’s true value-irrelevance, rather than to the impounding of new value-enhancing information by sophisticated investors. I offer three pieces of evidence that ...

I examine the informational contributions and effects on transitory volatility of trades initiated by different types of traders in three actively traded index futures markets. The results show that trades initiated by exchange member firms account for more than 60% of price discovery during the trading day. These institutional trades appear to be more informative than trades of individual exch...

We analyse the value of information in a stock market where information can be noisy and costly, using techniques from empirical game theory. Previous work has shown that the value of information follows a J-curve, where averagely informed traders perform below market average, and only insiders prevail. Here we show that both noise and cost can change this picture, in several cases leading to o...

The literature views aggressive trading behavior as the key for representativeness heuristic traders to survive in competition with rational traders. This paper provides another reason. That is, in this dynamic model of a competitive securities market, representativeness heuristic traders can derive more expected profit from the misvaluations (created by noise traders) than can rational traders...

This paper demonstrates that “grandfathering” of pollution rights may be inefficient when existing polluters enjoy market power or when there are increasing returns to abatement efforts. On the other hand an “auction and refund” approach, by effectively charging producers for the pollution they cause and refunding them in proportion to the value of their economic output levels, will result in g...

This paper examines the effect of introducing insider tratlin~; restrictions on the behaviour of the Amsterdam Stock Exchange. From 198'7 on, insiders are no longer allowed to trade two months before an annual earnings announcement. The results indicate that stocks became less liquid (when liquidity is measured by trading volume) when insiders were not allowed to trade. We also find some eviden...

This paper focuses on the post-war process of creation of a global trading system and integration of world trade. As the former came into being, multilateral trade liberalization became an on-going feature of the global economy facilitating international trade, consequently importance of international trade in the global economy increased dramatically. Since the mid-1980s, mindset of policy mak...

in this paper, we are examining the relationship between stock trading costs and commitment components and find both abnormal and normal commitments associated with these costs are associated. moreover, stock trading costs have a greater influence by both abnormal and normal negative commitments more than positive commitments. further analysis has shown that in general, investors are unable to ...

We introduce a new family of online learning algorithms based upon constraining the velocity flow over a distribution of weight vectors. In particular, we show how to effectively herd a Gaussian weight vector distribution by trading off velocity constraints with a loss function. By uniformly bounding this loss function, we demonstrate how to solve the resulting optimization analytically. We com...
