Stationary equilibria in asset-pricing models with incomplete markets and collateral
We consider an infinite-horizon exchange economy with incomplete markets and collateral constraints. As in the two-period model of Geanakoplos and Zame (2002), households can default on their liabilities at any time, and financial securities are only traded if the promises associated with these securities are backed by collateral. We examine an economy with a single perishable...

Computing moments of ratios of quadratic forms in normal variables
The accuracy and speed of numerical methods for computing the moments of a ratio of quadratic forms in normal variables is examined, with particular application to the sample autocorrelation function. Methods based on a saddlepoint approximation are demonstrated to be not only superior to existing approximations, but are numerically reliable and virtually as accurate as the method...

Real-Time Synchronised Petri Nets
This paper presents the combination of two well established principles: the CO-OPN synchronisation mechanism, and the Merlin and Farber time Petri nets. Real-time synchronised Petri nets systems are then defined such that a Petri net is an object that can ask to be synchronised with another net, and whose transition firing is constrained by relative time intervals. Our proposal...

Towards a Secure and Efficient Model for Grid Computing using Mobile Code
Mobile code has often been mentioned as an attractive technol- ogy for distributing computations inside a Grid consisting of heterogeneous nodes interconnected by a large-scale network. We describe here a Java-based mobile agent model for a Grid infrastructure which addresses issues such as customizable distribution of computation, security, billing and accounting.

MobiHealth - innovative 2.5 / 3G mobile services and applications for healthcare
MobiHealth aims at introducing new mobile valueadded services in the area of healthcare, based on 2.5 (GPRS) and 3G (UMTS) technologies, thus promoting the use and deployment of GPRS and UMTS. This will be achieved by the integration of sensors and actuators to a Wireless Body Area Network (BAN). These sensors and actuators will continuously measure and transmit vital constants along...

A Wave-guide Model for Packetized Media Streaming in Lossless Networks
Optimal operation of network based multimedia applications requires a precise specification of the network parameters. Different models have been used in the past in calculating the behavior of the network and defining parameters like throughput and delays of packets, using among others fluid analogy. In this paper we extend the bundled packet level perspective towards the...

Bidder Behavior in Multiunit Auctions: Evidencefrom Swedish Treasury Auctions
We analyze a unique data set on multiunit auctions, which contains the actual demand schedules of the bidders as well as the auctionawards in over 400 Swedish Treasury auctions. First, we document that bidders vary their prices, bid dispersion, and the quantity demanded in response to increased uncertainty at the time of bidding. Second,we find that bid shading can be explained by a...

Asset Pricing under the Quadratic Class
We identify and characterize a class of term structure models where bond yields are quadratic functions of the state vector. We label this class the quadratic class and aim to lay a solid theoretical foundation for its future empirical application. We consider asset pricing in general and derivative pricing in particular under the quadratic class. We provide two general transform...

A Descriptive Analysis of the Finnish Treasury Bond Market 1991-1999
This paper presents a descriptive analysis of the primary and secondary market for Finnish treasury bonds. The paper focuses on three issues. First, we report basic descriptive statistics such as auction volumes and secondary market yields and volumes. Second, we estimate the revenues earned by primary dealers from the treasury bond market. Third, we analyse the development of the...

Agency and the pace of adoption of new techniques
We study the relation of financial development and the pace of technological advance in a dynamic agency theoretic model. A firm which is financed by outside shareholders but run by managers has the prospect of a process innovation which arrives stochastically. Adopting the innovation requires firing old management and hiring new with skills appropriate for the new technique. We show...

Collateral and short squeezing of liquidity in fixed rate tenders
The paper models fixed rate tenders, where a central bank offers to lend central bank funds to financial institutions. Bidders are constrained by the amount of collateral they have. We focus on the strategic interaction between bidding in the tender and trading in the interbank market after the tender, where short squeezes could occur. We examine how the design of the tender affects...
