Modern ICT services are characterized by pervasive connectivity and the need for applications that are always on (24/7); a new way of designing and operating such services is therefore essential. To cope with these requirements, a proper system architecture design and an effective and efficient...

In this study we examine how party size and dining time affect tipping behavior using data from a large-scale transaction database (n 800,000) for a Norwegian restaurant chain. The data consist of detailed information about meal and drink choices, party size, and dining time as well as total...

Existing literature in economics and psychology has documented that individuals care about their social image. However, most of the existing evidence is based on laboratory experiments, where the concern for social image is artificially induced. We hand-collect a unique data set on restaurant...

Recent policy debate on minimum wages has focused not only on raising the minimum wage, but on eliminating the tip credit for restaurant workers. We use data on past variation in tip credits - or minimum wages for restaurant workers - to provide evidence on the potential impacts of eliminating...

Social distancing via shelter-in-place strategies has emerged as the most effective way to combat Covid-19. In the United States, choices about such policies are made by individual states. Here we show that the policy choice made by one state influences the incentives that other states face to...

We examine whether analysts tip investors during investor conferences. We find that conference-day abnormal returns of a presenting company are about 0.6% higher when the conference is hosted by an analyst who will initiate coverage with a Buy recommendation than when the conference is hosted by...

This paper experimentally investigates the impact of suggestive messages and tipping on a third party's judgment. The experimental design uses a model with three players, wherein two players (A and B) create a joint project, and the third player (C) decides how to divide the project's earnings...

This paper explores how changes in default options can influence consumer behavior in a setting where consumers can use a suggested default or manually enter a tip amount. To identify the impact that different defaults have on behavior, I take advantage of variation within the New York City taxi...

We study the impact of tipping in a service facility on the server's tipping wage, in the presence of an endogenously formed social norm. The problem is modeled as a two-stage tipping game: In the first stage, delay-sensitive customers arrive at an M/M/1 facility and decide whether to join or...

We examine trading activity around insider transactions on the Toronto Stock Exchange and find evidence that some traders mimic insider positions. Our unique dataset allows us to establish a direct connection between insiders, their brokerages, and the brokerages' other clients. The findings are...
