Summary
Introduction
Theory, experiment and practice suggest that, when bidder valuations for multiple objects are super-additive, combinatorial auctions are needed to increase efficiency, seller revenue, and bidder willingness to participate (Bykowsky et al. 2000, Rassenti et al. 1982, Ledyard et al. 2002). A combinatorial auction is an auction in which bidders are allowed to express bids in terms of packages of objects. The now famous FCC spectrum auctions are a good example of the relevance of these issues. In 41 auction events from 1994 to 2003, the FCC used what is known as a Simultaneous Multiple Round (SMR) auction to allocate spectrum and raise over $40 billion in revenue. This auction format does not allow package bidding. The FCC auctions also divide the spectrum by geographic location. It is reasonable to expect that some bidders might receive extra benefits by obtaining larger, more contiguous portions of the spectrum. A firm might enjoy cost savings if they could purchase two adjacent locations. However, without package bidding, a bidder cannot express that preference, potentially lowering the efficiency and revenue of the auction. If the bidder attempts to acquire both licenses through bidding on the licenses individually, they might be forced to expose themselves to potential losses. The high number of bidder defaults on payments might, in part, be evidence of losses caused by the lack of package bidding. In response to these difficulties, the FCC plans to allow package bidding in future auctions (Federal Communications Commission 2002, Dunford et al. 2001). In particular, the FCC in its auction #31 for the upper 700 MHz band, affords bidders the ability to submit bids for packages of licenses. The particular design presented in this paper was developed prior to the FCC package auction design. Indeed one of the major features of the FCC design was clearly influenced by the pricing rules we developed herein.

Summary
Introduction
During the discussion and evaluation of proposals for the design of the Federal Communications Commission (FCC) mechanism to sell the spectrum, over 130 auctions were run under controlled conditions at Caltech for the National Telecommunications and Information Administration (NTIA), the FCC, and others. While these data were used in those debates, we do not intend to relive that process here. Instead, in this paper, we reexamine these data and try to extract some useful information for those who may, in the future, be involved in the difficult task of creating mechanisms to auction multiple items.
The two major design questions we can say something about are (1) should the items be auctioned off sequentially or simultaneously? and (2) should package bidding be allowed? Ourmain conclusion is that, over a very wide range of environments, package bidding mechanisms (weakly) dominate simultaneous mechanisms, which in turn (weakly) dominate sequential mechanisms. This conclusion is based on three observations derived from a close look at the data.
First, in environments with multiple items to be allocated, if those items are homogeneous and substitutes, then little coordination between buyers is needed and the only role of the mechanism is to sort bidders with high values from bidders with low values. Both the sequential and simultaneous mechanisms seem to work very well at finding efficient allocations in these “easy” environments.
Second, in environments with multiple items to be allocated, if those items are heterogeneous, then some coordination among bidders is necessary to achieve high-value allocations even if there are only low synergy values. Simultaneous auctions provide a first step at this coordination that sequential auctions might have difficulty in providing.
Third, in environments with heterogeneous goods exhibiting complementarities, significant coordination is required for an auction or allocation mechanism to perform well with respect to efficiency or revenue. Sequential auctions perform poorly. Simultaneity is clearly necessary but not sufficient to attain high efficiencies.

Summary
Introduction
Combinatorial auctions enhance our ability to efficiently allocate multiple resources in complex economic environments. They explicitly allow buyers and sellers of goods and services to bid on packages of items with related values or costs. For example, “I bid $10 to buy 1 unit of item A and 2 units of item B, but I won't pay anything unless I get everything.” They also allow buyers, sellers and the auctioneer to impose logical constraints that limit the feasible set of auction allocations. For example, “I bid $12 to buy 2 units of item C OR $15 to buy 3 units of item D, but I don't want both.” Finally, they can handle functional relationships amongst bids or allocations, such as budget constraints or aggregation limits that allow many bids to be connected together. For example, “I won't spend more than a total of $35 on all my bids” or “This auction will allocate no more than a total of 7 units of items F, G and H.”
There are several reasons to prefer to have the bidding message space expanded beyond the simple space used for traditional single commodity auctions. As Bykowsky et al. (2000) point out, when values have strong complementarities, there is a danger of ‘financial exposure’ that results in losses to bidders if combinatorial bidding is not allowed. For example, in the case of complementary items such as airport take-off and landing times, the ability to reduce uncertainty to the bidder by allowing him to precisely declare his object of value, a cycle of slots for an entire daily flight pattern, is obvious: one component slot not acquired ruins the value of the flight cycle. In the same situation substitution possibilities would also be important to consider: if flight cycle A is not won, cycle B may be an appropriate though less valuable substitute for the crew and equipment available. Allocation inefficiencies due to financial exposure in noncombinatorial auctions have been frequently demonstrated in experiments beginning with Rassenti et al. (1982) (see also Porter (1999), Banks et al. (1989), Ledyard et al. (2002) and Kwasnika et al. (1998)).

OBJECTIVE
To measure transmission frequencies and risk factors for household acquisition of community-associated and healthcare-associated (HA-) methicillin-resistant Staphylococcus aureus (MRSA).
DESIGNProspective cohort study from October 4, 2008, through December 3, 2012.
SETTINGSeven acute care hospitals in or near Toronto, Canada.
PARTICIPANTSTotal of 99 MRSA-colonized or MRSA-infected case patients and 183 household contacts.
METHODSBaseline interviews were conducted, and surveillance cultures were collected monthly for 3 months from household members, pets, and 8 prespecified high-use environmental locations. Isolates underwent pulsed-field gel electrophoresis and staphylococcal cassette chromosome mec typing.
RESULTSOverall, of 183 household contacts 89 (49%) were MRSA colonized, with 56 (31%) detected at baseline. MRSA transmission from index case to contacts negative at baseline occurred in 27 (40%) of 68 followed-up households. Strains were identical within households. The transmission risk for HA-MRSA was 39% compared with 40% (P=.95) for community-associated MRSA. HA-MRSA index cases were more likely to be older and not practice infection control measures (P=.002–.03). Household acquisition risk factors included requiring assistance and sharing bath towels (P=.001–.03). Environmental contamination was identified in 78 (79%) of 99 households and was more common in HA-MRSA households.
CONCLUSIONHousehold transmission of community-associated and HA-MRSA strains was common and the difference in transmission risk was not statistically significant.

Summary
Joyce (1984) reports the results of experiments with a Walrasian tâtonnement auction that show that the mechanism is stable, exhibits strong convergence properties, and generates efficiencies that average better than 97%. He also found that when subjects could see part of the order flow (excess demand), prices tended to be lower. His experiments consisted of a stationary environment where subjects were provided single unit supply and demand functions.We assess the robustness of his results in a more general multiunit per subject setting; and we systematically investigate the effect of various rules about order flow information and message restriction rules on the performance of the Walrasian mechanism.
Our experiments are motivated by several considerations.
1. When there are both buyers and sellers in the market, each of which has one unit to buy or sell, the only Nash equilibria of the Walrasian tâtonnement mechanism are those that support the competitive equilibrium outcome. Furthermore, a Walrasian tâtonnement process can be designed that has a dominant strategy equilibrium where each participant reveals value or cost (see McAfee, 1992). The design imposes constraints on participant messages; specifically, at the announced price at t, if excess demand is positive (negative), any seller (buyer) not registering a sell (buy) order at t cannot register an order at time t + 1. Without this improvement rule, the dominant strategy equilibrium outcome no longer exists.But even with this improvement rule, the dominant strategy revelation property does not hold when demands and supplies are multiunit, since a participant may influence price without being entirely out of the market.

Summary
Rational expectations models predict that if individuals have common expectations (or priors) as to the value of an asset, and this common value is equal to the dividend value of the asset, then trades, if they occur, will be at prices near intrinsic dividend value (Tirole, 1982). Contrary to this, consider the data in Figure 18.1 which lists the average weekly share price and corresponding net asset value (NAV) for the Spain Fund. The price of the Spain Fund shares from July 1989 to August 1990 begins at a discount from NAV, rises to a premium of 250% over NAV by week 15, and ultimately “crashes” back to a discount by week 61.There is much controversy over the behavior of closed end funds, which still remains a puzzle for a rational expectations theory of asset pricing (see Lee et al., 1991).
Explanations of deviations from NAV rely on models that focus on distinct investor types and their expectations. Instead of entering the debate concerning the interpretation of the price behavior of closed end funds, we shall rely on laboratory methods in economics that allow us to investigate propositions on price formation in a controlled fundamental value environment. In the economy, control over fundamental value and investor information is rarely possible; therefore, minimal conditions for studying the role of expectations in stock market valuations cannot be identified. Smith et al. (1988; hereafter SSW) report the results of laboratory asset markets in which each trader receives an initial portfolio of cash and shares of a security with a dividend horizon of 15 trading periods. Before the tth trading period, the expected dividend value of a share [e.g., $0.24(15 − t + 1)]…

Recent trends in capital budgeting have been toward more complex decision rules with increasingly sophisticated treatments of risk. Although they have the virtue of simplicity, undiscounted methods such as the payback do not account for the time value of money. Net present value and internal rate of return consider the time value of money but many questions remain about the proper discount rate, the reinvestment assumption, and the statistical interrelations among projects. The latest approaches, referred to as portfolio models, are substantially more complicated but are the only methods that consider the statistical interrelations among the various assets. The most popular portfolio approach has been the mean-variance (E-V) model developed by Sharpe [10] and Lintner [5].
