This paper studies optimal nonlinear pricing for a monopolist when consumers’ preferences exhibit temptation and self-control as in Gul and Pesendorfer (2001a). Consumers are subject to temptation inside the store but exercise self-control, and those foreseeing large self-control costs do not enter the store. Consumers differ in their preferences under temptation. When all consumers are tempted...

This note presents a detailed formal derivation of the equilibrium conditions of a variation of the deep habit model developed by Ravn, Schmitt-Grohé, and Uribe (2003). In the present note, the single-period utility function depends on the quasi ratio of current consumption to the stock of habit of each variety, whereas in the original deep habit model it depends on the quasi difference of thes...

A buyer wishes to purchase a good from a seller who chooses a sequence of prices over time. Each period the buyer can also exercise an outside option, abandoning their search or moving on to another seller. We show there is a unique equilibrium in which the seller charges a constant price in every period equal to the monopoly price, contravening the Coase conjecture. We then embed the singlesel...

To distribute software, commercial firms have the opportunity to use some dual licensing strategy i.e. to provide their software under two different licensing terms (proprietary and open source). In this paper, we investigate the relevance and impacts of such distribution strategy in the presence of an already existing open source software. In this competitive setting, we determine in which con...

In liability lawsuits (e.g., patent infringement), a plaintiff demands compensation from defendant, and the parties often negotiate settlement to avoid costly trial. Liability insurance creates bargaining leverage for defendant in this negotiation. We study characteristics of monopoly equilibrium contracts settings where effect is substantial source value insurance. Our results show that under ...

The mathematical framework of psychological game theory is useful for describing many forms motivation where preferences depend directly on one’s own or others’ beliefs. It allows incorporating, example, emotions, reciprocity, image concerns, and self-esteem in economic analysis. We explain how why, discussing basic theory, experiments, applied work, methodology. (JEL C70, D83, D91)

An optical dual sensor for oxygen and temperature is presented that is highly oxygen sensitive and covers a broad temperature range. Dual sensing is based on luminescence lifetime measurements. The novel sensor contains two luminescent compounds incorporated into polymer films. The temperature-sensitive dye (ruthenium tris-1,10-phenanthroline) has a highly temperature-dependent luminescence and...

American industries have grown more concentrated over the last 40 years. In absence of productivity innovation, this should lead to price hikes and output reductions, decreasing consumer welfare. With US census data from 1972 2012, I use disentangle revenue output. Industry-level estimates show that concentration increases are positively correlated real growth, uncorrelated with changes overall...
