In this paper we study the problem of patrolling a perimeter. The general situation considered here can correspond to different tactical problems and it is studied from the point of view of game theory. To put the ideas in a context we describe it as follows. An intruder seeks to carry out a...

Despite descriptive empirical evidence on start-up numbers and survival rates of young firms, the interaction of market entry decisions and reactions of incumbent competitors is still insufficiently understood in the entrepreneurship literature. Repeated games offer a suitable theoretical...

Der vorliegende Diskussionsbeitrag entstand im Rahmen eines Forschungsprojektes über die monetäre Integration von fünf mittel- und osteuropäischen EU-Beitrittskandidaten (Polen, Tschechische Republik, Ungarn, Slowenien und Estland). Das hier vorgestellte Kapitel geht auf die...

Discouragement is a process occurring during an unemployment spell. As the spell prolongs, an individual gradually realises that the returns to search can no longer outweigh search costs, and hence she may eventually leave the labour force. This is analysed theoretically in a framework of...

Interdiction operations involving search, identification, and interception of suspected objects are of great interest and high operational importance to military and naval forces as well as nation’s coast guards and border patrols. The interdiction scenario discussed in this paper includes an...

In this note I discuss the condition for indeterminacy in the context of search models with increasing returns in the matching technology. Building on the theoretical framework set forth by Giammarioli (2003), I argue that increasing returns with respect to vacancies at the aggregate level is...

In this paper I argue that search theory is a useful addition to the way economists and geographers have approached the study of commuting behavior. This is illustrated by showing that introduction of a spatial element into the standard model of job search leads to the prediction of critical...

Nancy Cartwright views models as blueprints for nomological machines - machines which, if properly shielded, generate lawlike behaviour or regularities. Marcel Boumans has argued that we can look for devices inside models which enable us to measure aspects of these regularities. So, if models do...

Using 'search' theory, technology adoption is conceived of as a critical factor in the aftermath of a technological shock, which increases employment in the leading sectors and total output in the economy. These implications are further investigated in the present paper, both formally and...

In a dynamic general equilibrium model with endogenous markups and labor market frictions, we investigate the effects of increased product market competition. Unlike most macroeconomic models of search, we endogenize the labor supply along the extensive margin. We show that beneficial effects in...
