    A Dynamic MDS-Based Localization Algorithm for Mobile Sensor Networks

    In this paper, the authors proposed a dynamic mobility-assisted MDS-based localization algorithms for sparse mobile sensor network. For sparse networks, the assumption of the existing MDS-based localization algorithms is not necessary valid and the network may even be nonrigid, which significantly affects the application and accuracy of the existing MDS-based...

    Trade Models With Heterogeneous Firms: What About Importing?

    Intermediate goods make up a large share of world trade. Yet trade models with heterogeneous firms focus almost exclusively on firms' export decisions rather than their import decisions. The authors develop an analytically solvable model of a small open economy in which heterogeneous firms make endogenous import decisions. Firms weigh...

    Searchable Compression

    The authors are interested in structuring data compression to support efficient searching of information in the compressed data domain. Specifically, by "Searchable" they mean a layered coding such that certain information can be extracted from the compressed bit-stream without requiring complete decoding of all compressed information. The chain rule for...

    Opportunity Knocks: An Economic Analysis Of Television Advertisements

    Certain aspects of advertising - especially on television - are not easily explained with conventional economic models. In particular, much of the imagery and repetitive thematic content seen in advertisements seem "Psychological" in nature, as opposed to "Informative." To understand the economic rationale for this phenomenon, the authors develop a...

    Effects Of Food Safety Information On Consumer Behavior: Evidence From U.S. Household-Level Data

    Many factors can influence consumer purchasing habits, including food safety information. While concerns about food safety are likely to be influenced by idiosyncratic experiences, general media information on the safety of meat and poultry may also affect purchase decisions. The reaction of consumers to changes in the amount of food...

    The Agglomeration Of Exporters By Destination

    Precise characterization of informational trade barriers is neither well documented nor understood. Using Russian customs data, the authors find exporting firms agglomerate geographically with respect to their shipment's destination in addition to agglomeration around ports, suggesting behavior responding to a trade barrier. To account for this fact, they build on...

    Comparing The Economic Impact Of An Export Shock In Two Modeling Frameworks

    Because of more restrictive assumptions on regional Input-Output (IO) models compared to Computable General Equilibrium (CGE) models, the literature agrees IO results are intuitively consistent with long run equilibrium but otherwise overestimated. The authors compare the results of IO and CGE models from an exogenous export shock under various labor...
