A new simple construction of an aperiodic tile set based on self-referential (fixed point) argument is proposed. People often say about some discovery that it appeared “ahead of time”, meaning that it could be fully understood only in the context of ideas developed later. For the topic of this note, the construction of an aperiodic tile set based on the fixed-point (self-referential) approach, ...

In this research, we empirically investigate the payoff of aggressive bidding in an online auction. To address our research question, we use a unique and very rich dataset containing actual market transaction data for approximately 7,000 pay-per-bid auctions. Our research design allows us to isolate the impact of bidding aggressively in an attempt to signal a high valuation on the probability t...
