The VLA-COSMOS Large Project has imaged the 2 deg COSMOS field with a resolution of 1.5 arcsec and a sensitivity of about 11 μJy (1σ) yielding to a catalog of ∼ 3600 radio sources. In this paper we present a further analysis of the VLA-COSMOS Large Project catalog of radio sources aimed to: 1) quantify and correct for the effect of bandwidth smearing in the catalog, 2) determine the incompleten...

We examine the effect of direct mail (commonly referred to as junk mail) advertising on individual financial decisions by studying consumer choice of debt contracts. Consistent with the theoretical predictions, we find that financial variables underlying the relative pricing of debt contracts are the leading factors explaining consumers debt choice. Furthermore, we also find that the intended u...

Information asymmetries are important in theory but difficult to identify in practice. We estimate the presence and importance of hidden information and hidden action problems in a consumer credit market using a new field experiment methodology. We randomized 58,000 direct mail offers to former clients of a major South African lender along three dimensions: (i) an initial “offer interest rate” ...

Research has shown that extrinsic incentives can crowd out intrinsic motivation in many contexts. Despite this, many nonprofits offer conditional thank-you gifts, such as mugs or tote bags, in exchange for donations. In collaboration with a nonprofit, this study implements a direct mail field experiment and demonstrates that thank-you gifts reduced donation rates in a fundraising campaign. Atte...

One to one (1:1) marketing services (e.g., customized advertisements, promotions and direct mail) are a growth industry.
