On the possible volume of $mu$-$(v,k,t)$ trades
A $mu$-way $(v,k,t)$ $trade$ of volume $m$ consists of $mu$ disjoint collections $T_1$, $T_2, dots T_{mu}$, each of $m$ blocks, such that for every $t$-subset of $v$-set $V$ the number of blocks containing this t-subset is the same in each $T_i (1leq i leq mu)$. In other words any pair of collections ${T_i,T_j}$, $1leq i< j leq mu$ is a $(v,k,t)$ trade of volume $m$. In th...
متن کاملAre Payment Card Contracts Unfair? (Short Paper)
Fraud victims are often refused a refund by their bank on the grounds that they failed to comply with their bank’s terms and conditions about PIN safety. We, therefore, conducted a survey of how many PINs people have, and how they manage them. We found that while only a third of PINs are ever changed, almost half of bank customers write at least one PIN down. We also found bank conditions that ...
متن کاملAsset Prices Under Short-Sale Constraints
In this paper, we study how short-sale constraints affect asset price and market efficiency. We consider a fully rational expectations equilibrium model, in which investors trade for two reasons, to share risk and to speculate on private information, but they face short-sale constraints. Short-sale constraints limit both types of trades, and thus reduce the allocational and informational effici...
متن کاملOverconfidence , Short - Sale Constraints , and Bubbles ∗
Motivated by the behavior of internet stock prices in 1998-2000, we present a continuous time equilibrium model of bubbles where overconfidence generates agreements to disagree among agents about asset fundamentals. With a short-sale constraint, an asset owner has an option to sell the asset to other agents when they have more optimistic beliefs. This re-sale option has a recursive structure, t...
متن کاملPossible volumes of t-(v, t+1) Latin trades
The concept of t-(v, k) trades of block designs previously has been studied in detail. See for example A. S. Hedayat (1990) and Billington (2003). Also Latin trades have been studied in detail under various names, see A. D. Keedwell (2004) for a survey. Recently Khanban, Mahdian and Mahmoodian have extended the concept of Latin trades and introduced t-(v, k) Latin trades. Here we study the spec...
