<title>Race Effects on eBay</title>

	<p>We investigate the impact of seller race in a field experiment involving baseball card auctions on eBay. Photographs showed the cards held by either a dark-skinned/African-American hand or a light-skinned/Caucasian hand. Cards held by African-American sellers sold for approximately 20% ($0.90) less than cards held by Caucasian sellers, and the race effect was more pronounced in sales of minority player cards. Our evidence of race differentials is important because the on-line environment is well controlled (with the absence of confounding tester effects) and because the results show that race effects can persist in a thick real-world market such as eBay.</p>

<title>Regulating Opt Out: An Economic Theory of Altering Rules</title>

	<p>Whenever a rule is contractible, the law must establish separate rules governing how private parties can contract around the default legal treatment. To date, contract theorists have not developed satisfying theories for how optimally to set “altering rules,” the rules that set out the necessary and sufficient conditions for displacing a default. This Article argues that efficiency-minded lawmakers in setting altering rules should consider both the costs of altering and the costs of various kinds of error. There are two broad reasons for altering rules to deviate from attempts to minimize the transaction cost of altering, First, the Article develops theoretical conditions when minimizing the costs of party error (especially non-drafter error) and third-party error (especial judicial error) will be paramount. The Article proposes a variety of specific altering interventions – including “train and test” altering rules, “arbitrary” altering rules, and “thought-requiring” altering rules that might be deployed to reduce altering error. Second, when externalities or paternalism concerns are insufficient to justify a full-blown mandatory rule, lawmakers might usefully impose “impeding” altering rules which deter subsets of contractors from contracting for legally dispreferred provisions. Impeding altering rules produce an intermediate category of “quasi-mandatory” or “sticky default” rule which manage but do not eliminate externalities and paternalism concerns. These two deviations from transaction-cost minimization can often be usefully complemented by what this Article calls “altering penalties” which penalize one or both contractors who utilize dispreferred altering methods. Specifically, altering penalties can channel contractors’ altering efforts toward means that better reduce error or better control externalities or paternalism. More explicitly theorizing altering rules as a distinct category of law can make visible legal issues that have largely gone unnoticed and lead toward the development of more defensible choices about how best to regulate opt out.</p>

<title>Diversification Across Time</title>

	<![CDATA[
	<p>By employing leverage to gain more exposure to stocks when young, individuals can achieve better diversification across time. Using stock data going back to 1871, we show that early leverage combined with reduced equity exposure when older can reduce lifetime portfolio risk. For example, an initially-leveraged portfolio can produce the same mean accumulation as a constant 75% stock allocation with a 21% smaller standard deviation. Since the mean accumulation is the same, the reduction in volatility does not depend on the equity premium. A leveraged lifecycle strategy can also allow investors to come closer to their utility-maximizing allocation. If risk preferences would lead an investor to allocate 50% of his discounted retirement savings to stocks, that would require a young investor to put well more than 50% of his liquid savings into stocks. We employ leverage (limited to 2:1) to help the investor overcome a limited ability to borrow against human capital. Based on historical returns, we find a 37% improvement in the certainty equivalent (for CRRA=4). Monte Carlo simulations show that these gains continue even with equity premia well below the historical average.</p>

	<p>By employing leverage to gain more exposure to stocks when young, individuals can achieve better diversification across time. Using stock data going back to 1871, we show that buying stock on margin when young combined with more conservative investments when older stochastically dominates standard investment strategies—both traditional life-cycle investments and 100%-stock investments. The expected retirement wealth is 90% higher compared to life-cycle funds and 19% higher compared to 100% stock investments. The expected gain would allow workers to retire almost six years earlier or extend their standard of living during retirement by 27 years.</p>

<title>Going Soft on Microsoft? The EU&apos;s Antitrust Case and Remedy</title>

	<![CDATA[
	<p>In March 2004, following a five-year investigation, the European Commission found Microsoft liable for illegally tying the Windows Media Player to the Windows operating system. This Column evaluates the antitrust issues and the proposed remedy. What is remarkable is that the remedy eliminates false positives.  Just as King Solomon's proposal to divide the baby only caused pain to the true mother, the Commission's remedy will only cause pain to a monopolist who abused its position.</p>

	<p>An NBA referee has now pleaded guilty, and forensic economists have found signs of bias and cheating in the NBA, college basketball and sumo wresting.  Ian Ayres argues that the NBA should release referee data to allow forensic economists to look for statistical evidence of malfeasance, before credibility in results is lost.</p>

<title>Optimal Delegation and Decoupling in the Design of Liability Rules</title>
<link>http://works.bepress.com/ian_ayres/15</link>

	<![CDATA[
	<p>The central allocative decision confronting a judge in a nuisance dispute should not concern the identity of the initial entitlement recipient but rather the identity of the more efficient chooser—the litigant who can more efficiently allocate the entitlement. We show that liability rules can produce four basic allocations which differ centrally in the ways in which courts delegate to litigants the authority to ultimately allocate the entitlement. Two classes concern "single chooser" rules that vest (in the absence of an agreement to the contrary) the allocative decision solely in one of the litigants. The other two classes concern a new type of rule, "dual chooser" rules, that allow either party to veto the transfer of an entitlement. Dualchooser rules are more than a theoretical curiosity both because they exist in our current law and because at times they produce systematically greater allocative efficiency than either type of single-chooser rule. Two heads are sometimes better than one.</p>
<p>A central result of the paper is that in choosing among different liability rules allocative concerns can be decoupled from distributive concerns. There exist an infinite number of liability rules which produce each of the four basic allocations, but every rule within a particular class divides differently between the litigants the expected value of the allocation. To successfully decouple, courts should at times impose "call option," "put option," "Pay or be Paid," and "Pay or Pay" rules.</p>

<title>Should Heterosexuals Boycott Marriage?</title>
<link>http://works.bepress.com/ian_ayres/14</link>

	<![CDATA[
	<p>This essay asks a seemingly simple question: Can it ever be ethical to take a benefit that is invidiously denied others?  Posed in such stark terms, the question seems to admit only one answer: “no.”  But many, many heterosexuals voluntarily accept the benefits of marriage that are invidiously denied to their gay friends and family.  This essay is an attempt to reconcile this conflict.  The reconciliation we propose avoids total renunciation.  Instead, we suggest a theory of limited disgorgement, a pragmatic formula to determine how much privileged people should give up if they decide to accept benefits invidiously denied to others.</p>

<title>Should Campaign Donors Be Identified?</title>
<link>http://works.bepress.com/ian_ayres/13</link>

	<![CDATA[
	<p>About the only campaign finance issue on which there is a strong consensus is the belief that the law should force candidates to disclose the identity of contributors. A growing group of scholars and advocates believe that mandated disclosure should be the only campaign finance regulation; they argue that other restrictions are counterproductive because they tend to shift money to less accountable forms of political speech such as "independent expenditures" and "issue advocacy."</p>
<p>Representative John T. Doolittle (R-Calif.) has proposed the "Citizen Legislature and Political Freedom Act" that essentially would repeal all limits on political campaign contributions and merely require immediate disclosure by candidates when they do receive contributions. This type of "pure disclosure" reform has garnered support from a wide spectrum of political activists, from Sen. Mitch McConnell (R-Ky.) to Stanford Law School dean Kathleen Sullivan.</p>
<p>But there exists in our polity a counter-image--the voting booth--that stands against the cult of disclosure. Ballot secrecy was adopted toward the end of the nineteenth century to deter political corruption. Voting booth privacy disrupted the economics of vote buying, making it much more difficult for candidates to buy votes because, at the end of the day, they could never know for sure who voted for them.</p>
<p>A similar pro-anonymity argument can be applied to campaign finance. We could harness similar anonymity benefits by creating a "donation booth": a screen that forces donors to funnel campaign contributions through blind trusts that would keep candidates from learning the identity of their supporters. Just as the secret ballot makes it more difficult for candidates to buy votes, mandating anonymous donations through a system of blind trusts might make it harder for candidates to sell access or influence because they would never know which donors had paid the price. Knowledge about whether the other side actually fulfills his or her promise is an important prerequisite for trade. People--including political candidates--are less likely to deal if they are uncertain whether the other side performs.</p>

<title>Don’t Tell, Don’t Ask:  Narrow Tailoring After Grutter and Gratz</title>
<link>http://works.bepress.com/ian_ayres/10</link>
<guid isPermaLink="true">http://works.bepress.com/ian_ayres/10</guid>
<pubDate>Fri, 09 Nov 2007 12:12:41 PST</pubDate>
<description>
	<![CDATA[
	<p>The Supreme Court’s affirmative action decisions in Grutter v. Bollinger and Gratz v. Bollinger changed the meaning of “narrow tailoring.”  While the narrow tailoring requirement has always had multiple dimensions, a central meaning has been that the government must use the smallest racial preference needed to achieve its compelling interest.  We might have expected, therefore, that if the Court were to uphold one of the two programs at issue in Grutter and Gratz, it would, all other things being equal, uphold the program with smaller racial preferences.  We show, however, that the preferences in the admissions program upheld in Grutter were larger than the preferences in the admissions program struck down in Gratz.</p>
<p>This result was not necessarily wrong, but the Court’s analysis was wrong.   The Grutter and Gratz Courts replaced the “minimum necessary preference” requirement with a requirement that admissions programs provide “individualized consideration,” which we show amounts to a “Don’t Tell, Don’t Ask” regime.  The Court will not “ask” probing questions about the size and differentiation of preferences as long as the government decisionmaker does not “tell” the Court how much of a racial preference it is giving.  Indeed, as an example of the differential standards the Court applied, we demonstrate that while the Court impugned the admissions program at issue Gratz for making race decisive for “virtually every minimally qualified minority applicant,” in fact the fraction of qualified minority applicants for whom race was decisive was smaller in the admissions program struck down in Gratz than it was in the admissions program upheld in Grutter.</p>
<p>We call for a return to the minimum necessary preference requirement.  Instead of examining whether preferences are “individualized,” courts should determine whether the constitutionally relevant benefits of granting preferences of a given size outweigh the constitutionally relevant costs, both overall and at the margin.</p>

<title>Tradable Patent Rights: A New Approach to Innovation</title>

	<![CDATA[
	<p>Patent thickets may inefficient retard cumulative innovation. This paper explores two alternative mechanisms that may be used to weed out patent thickets. Both mechanisms are intended to reduce the number of patents in our society. The first mechanism we discuss is price based regulation of patents through a system of increasing renewal fees. The second and more innovative mechanism is quantity based regulation through the establishment of a system of Tradable Patent Rights. The formalization of tradable patent rights would essentially create a secondary market for patent permits in which patent protection will be bought and sold.</p>

	<p>Firms that are committed to employment equality for gay and lesbian workers don't need to wait for state or federal legislation.  A little-known type of intellectual property can allow individual corporations to privately opt into non-discrimination duties. We see this as a potential model for other civil rights or policy implementation.</p>

<title>Substitutes for Insider Trading</title>
<link>http://works.bepress.com/ian_ayres/4</link>

	<![CDATA[
	<p>When insider trading prohibitions limit the ability of insiders (or of a corporation itself) to use material non-public information to trade a particular firm’s stock, there may be incentive to use the information to trade instead on the stock of that firm’s rivals, suppliers, customers, or the manufacturers of complementary products. We refer to this form of trading as trading in stock substitutes. Stock substitute trading by a firm is legal. In many circumstance, substitute trading by employees is also legal. Trading in stock substitutes may be quite profitable, and there is anecdotal evidence that employees often engage in such trading. Our analysis suggests that substitute trading is less socially desirable than traditional insider trading. We recommend a set of disclosure rules designed to clarify existing law and provide information on the extent of stock substitute trading. We also discuss possible changes in the law that might limit inefficient trading in stock substitutes.</p>
