We document that market reactions to insider purchases and sales are different in terms of price and volume. With an extensive data set that covers the period from 1991 to 2006, we systematically segregate the asymmetric effects of these two types of insider transactions. We follow the design of previous studies (e.g., Basu, 1997; Ball and Shivakumar, 2005, Leone et al. 2006) to understand the ...

We introduce Large Scale Asset Purchases (LSAPs) in a New-Keynesian DSGE model that features distinct mortgage and corporate loan markets. We show that following a significant disruption of financial intermediation, central-bank purchases of mortgage-backed securities (MBS) are uniformly less effective at easing credit market conditions and stabilizing economic activity than outright purchases ...

In this study, that tries to understand adolescent buying behavior, and adolescent decision-making styles as input variable and online shopping behavior as output variable.

I propose a statistical model for purchase timing that exploits information on the shopping days of households. It delivers forecasts for the number of purchases in the next period and for the timing of the first and consecutive purchases. Purchase occasions a...

Farmer compared permanent tax-financed expenditure paths and showed tha...

In this work we study the OSPF protocol focussing our attention on the multi-area architecture. The target of the work is to model the multi-area OSPF and to analyze the complexity it introduces in the intra-domain routing. To make this we propose a model of the OSPF protocol. The aims of the model is to discover the routing choices performed by the routers without reproducing the exchange of i...
