Undisclosed orders and optimal submission strategies in a limit order market

Reserve orders enable traders to hide a portion of their orders and now appear in most electronic limit order markets. This paper outlines a theory to determine an optimal submission strategy in a limit order book, in which traders choose among limit, market, and reserve orders and simultaneously set price, quantity, and exposure. We show that reserve orders help traders compete for the provision of liquidity and reduce the friction generated by exposure costs. Therefore, total gains from trade increase. Large traders always benefit from reserve orders, whereas small traders benefit only when the tick size is large.     

Breast cancer risk perceptions and breast cancer worry: what predicts what?

This longitudinal study explored the relationship between perceived breast cancer risk and worry. We measured both absolute and comparative risk perceptions, and also used the Gail algorithm to assess the accuracy of participants' risk perceptions. Three hundred and one women ages 40–75 participated in a two‐part study assessing how format of breast cancer risk presentation affected perceptions of risk. Relative to their Gail scores, women were biased pessimistically about their own absolute breast cancer risk and yet largely accurate about their comparative breast cancer risk. Perceived comparative risk, but not perceived absolute risk or biases in absolute or comparative risk, predicted subsequent worry. Worry predicted subsequent perceived absolute risk and biases in absolute and comparative risk. These results suggest that women's emotional reactions to breast cancer risk are based on accurate (unbiased) perceptions of their comparative risks. In turn, greater worry prompts a re‐evaluation of absolute risk as well as changes in risk biases. Implications for screening are discussed.

Market makers as information providers: The natural experiment of STAR

Market makers are financial intermediaries who are supposed to provide additional liquidity, but do not have any information-related obligation. This paper studies the unique case of the Italian Stock Exchange, where market makers are also obliged to facilitate information disclosure about the firms they cover. We focus on a group of small/medium capitalization stocks (STAR) that are assigned a designated market maker (DMM) starting from 2001. We show that their liquidity requirements are not binding during the sample periods and that the main impact of DMMs' introduction is due to their obligations on information provision. We find that DMMs' activity as information providers reduces spread and price volatility, the probability of informed trading (PIN), and the adverse selection component of the spread. An event study provides evidence that the information released through DMMs is perceived as useful by market participants.     

Are property rights enough?Re‐evaluating a big‐bang claim1

We investigate the claim made by proponents of the big‐bang strategy that the establishment of property rights in an economy in transition creates its own demand for the enforcement of laws to protect those rights. Our model contains a government engaging in activities to accomplish objectives that depend on public support for the enforcement of the rule of law and agents who interpret the level of activities of the government as indications of the government's intent to enforce the rule of law. Agents, using the level of government activities as an input to their decisions, choose whether to support the government's objectives. We establish conditions under which the level of activities chosen by the government maximizes its benefits, and simultaneously induces the constituency to support enforcement of the rule of law. These conditions provide a basis for the argument for the implementation of the big‐bang policy. When these conditions do not hold, however, we show that the level of activities that maximizes the government's benefits may have only a minor impact on support for the enforcement of the rule of law. Two characteristics play an important role in these conditions: the initial level of crime and the types of activities the government chooses to undertake. We present examples showing that the initial level of crime has the more dramatic effect on subsequent support for the rule of law.
