Although much research has been conducted on employeesf extra-role behaviors (ERBs), the topic of how newcomers to an organization engage in ERBs remains relatively underexplored. Following social cognitive theory, we develop a dynamic model of newcomersf helping and voice as two types of ERBs....

We experimentally investigate the existence of and possible origin of the disposition effect. Our approach has three distinct characteristics: Firstly, we created an experimental environment that closely mimics a real stock market and were thus able to obtain and analyze trading behavior data...

This paper investigates the influence of weather on happiness. While previous studies have examined climatic influence by comparing the well-being of people living in different regions, this paper focuses on how daily changes in weather affect individuals living in a single location. Our data...

This paper provides a theoretical explanation for why the presence of asset bubbles can lead to higher economic growth in concurrence with high consumption by using a simple endogenous growth model. In the model economy, long-lived valuemaximizing firms continuously improve the quality of their...

We develop a competitive search model involving multiple regions, geographically mobile work- ers, and moving costs. Equilibrium mobility patterns are analyzed and characterized, indicating that shocks to a particular region, such as a productivity shock, can propagate to other regions through...

We reexamine indeterminacy and utility-generating public spending under balanced- budget rules in a simple one-sector growth model. The introduction of consumption tax (subsidy) as well as subsidies for savings and labor modify indeterminacy con- ditions in the existing studies. We show that if...
