Automating the Design of Graphical Presentations of Relational Information

by Jock Mackinlay - ACM Transactions on Graphics , 1986
"... The goal of the research described in this paper is to develop an application-independent presentation tool that automatically designs effective graphical presentations (such as bar charts, scatter plots, and connected graphs) of relational information. Two problems are raised by this goal: The codi ..."

Reputation and Imperfect Information

by David M. Kreps, Robert Wilson - Journal of Economic Theory , 1982
"... A common observation in the informal literature of economics (and elsewhere) is that in multistage “games, ” players may seek early in the game to acquire a reputation for being “tough ” or “benevolent ” or something else. But this phenomenon is not observed in some formal game-theoretic analyses of ..."

Using collaborative filtering to weave an information tapestry

by David Goldberg, David Nichols, Brian M. Oki, Douglas Terry - Communications of the ACM , 1992
"... predicated on the belief that information filtering can be more effective when humans are involved in the filtering process. Tapestry was designed to support both content-based filtering and collaborative filtering, which entails people collaborating to help each other perform filtering by recording ..."

Information flow and cooperative control of vehicle formations.

by J Alexander Fax , Richard M Murray - In Proceeings of 15th IFAC Conference, , 2002
"... Abstract We consider the problem of cooperation among a collection of vehicles performing a shared task using intervehicle communication to coordinate their actions. We apply tools from graph theory to relate the topology of the communication network to formation stability. We prove a Nyquist crite ..."
Abstract - Cited by 551 (11 self) - Add to MetaCart
criterion that uses the eigenvalues of the graph Laplacian matrix to determine the effect of the graph on formation stability. We also propose a method for decentralized information exchange between vehicles. This approach realizes a dynamical system that supplies each vehicle with a common reference

Querying Heterogeneous Information Sources Using Source Descriptions

by Alon Levy, Anand Rajaraman, Joann Ordille , 1996
"... We witness a rapid increase in the number of structured information sources that are available online, especially on the WWW. These sources include commercial databases on product information, stock market information, real estate, automobiles, and entertainment. We would like to use the data stored ..."
Abstract - Cited by 724 (34 self) - Add to MetaCart
-featured database systems and can answer only a small set of queries over their data (for example, forms on the WWW restrict the set of queries one can ask). (3) Since the number of sources is very large, effective techniques are needed to prune the set of information sources accessed to answer a query. (4

Measuring the information content of stock trades

by Joel Hasbrouck - Journal of Finance , 1991
"... This paper suggests that the interactions of security trades and quote revisions be modeled as a vector autoregressive system. Within this framework, a trade's information effect may be meaningfully measured as the ultimate price impact of the trade innovation. Estimates for a sample of NYSE is ..."

The effect of national culture on the choice of entry mode

by Bruce Kogut, Harbir Singh - Journal of International Business Studies , 1988
"... Abstract. Characteristics of national cultures have frequently been claimed to influence the selection of entry modes. This article investigates this claim by developing a theoretical argument for why culture should influence the choice of entry. Two hypotheses are derived which relate culture to en ..."
Abstract - Cited by 628 (0 self) - Add to MetaCart
to entry mode choice, one focussing on the cultural distance between countries, the other on attitudes towards uncertainty avoidance. Using a multinomial logit model and controlling for other effects, the hypotheses are tested by analyzing data on 228 entries into the United States market by acquisition

An Empirical Characterization of the Dynamic Effects of changes in Government Spending and Taxes on Output

by Olivier Blanchard, Roberto Perotti - QUARTERLY JOURNAL OF ECONOMICS , 2002
"... This paper characterizes the dynamic effects of shocks in government spending and taxes on U. S. activity in the postwar period. It does so by using a mixed structural VAR/event study approach. Identification is achieved by using institutional information about the tax and transfer systems to identi ..."

Selection on Observed and Unobserved Variables: Assessing the Effectiveness of Catholic Schools

by Joseph G. Altonji, Todd E. Elder, Christopher R. Taber , 2002
"... In this paper we measure the effect of Catholic high school attendance on educational attainment and test scores. Because we do not have a good instrumental variable for Catholic school attendance, we develop new estimation methods based on the idea that the amount of selection on the observed expla ..."
Abstract - Cited by 538 (14 self) - Add to MetaCart
explanatory variables in a model provides a guide to the amount of selection on the unobservables. We also propose an informal way to assess selectivity bias based on measuring the ratio of selection on unobservables to selection on observables that would be required if one is to attribute the entire effect

Sticky Information versus Sticky Prices: a Proposal to Replace the New Keynesian Phillips Curve

by N. Gregory Mankiw, Ricardo Reis , 2002
"... This paper examines a model of dynamic price adjustment based on the assumption that information disseminates slowly throughout the population. Compared with the commonly used sticky-price model, this sticky-information model displays three related properties that are more consistent with accepted v ..."
