Gift exchange and the separation of ownership and control
Numerous gift exchange experiments have found a positive relationship between employers’ wage offers and workers’ effort levels. In (almost) all these experiments the employer both owns and controls the firm. Yet in reality many firms are characterized by the separation of ownership and control. In this paper we explore to what extent this affects the wage-effort relationship observed. We compa...
متن کاملGift exchange and the separation of ownership and control
Numerous gift exchange experiments have found a positive wage-effort relationship. In (almost) all these experiments the employer both owns and controls the firm. This paper explores to what extent the separation of ownership and control affects the wage-effort relationship. We compare the standard bilateral gift exchange game between an owner-manager and a worker with two trilateral ones where...
متن کاملA centennial gift from Einstein.
The 1919 detection of the apparent displacement of background stars near the edge of the eclipsed Sun’s disk provided one of the first convincing proofs of Einstein’s theory of general relativity (1, 2). Almost 100 years later, Sahu et al. report on page 1046 of this issue the first measurement of the gravitational deflection of starlight by a star other than the Sun (3). Using the superior ang...
متن کاملHonoring a Gift from Kumbakonam
2 NOTICES OF THE AMS VOLUME 53, NUMBER 6 T oday was an absolutely glorious day in Madison, Wisconsin. It is Christmas 2005, and everyone in the house is asleep after a long day of enjoying family, opening presents, and eating enormous portions of mashed potatoes and yule log cake. Yet powerful images keep me awake. Thirty-six hours ago I returned from a six-day whirlwind journey to a far-off pl...
متن کاملSmart surfaces with switchable superoleophilicity and superoleophobicity in aqueous media: toward controllable oilwater separation
Advanced materials with surfaces that have controllable oil wettability when submerged in aqueous media have great potential for various underwater applications. Here we have developed smart surfaces on commonly used materials, including non-woven textiles and polyurethane sponges, which are able to switch between superoleophilicity and superoleophobicity in aqueous media. The smart surfaces ar...
