Investigation of dynamics of a virus–antivirus model in complex network

Ren, Jianguo; Xu, Yonghong; Liu, Jiming - In: Physica A: Statistical Mechanics and its Applications 421 (2015) C, pp. 533-540

In this paper, a new model of computer virus–antivirus propagation dynamics based on the topology nature of the … Internet is established. We analyze theoretically the complex dynamics of the model and it is found that, unlike the existing …

Network Analysis of Commuting Flows: A Comparative Static Approach to German Data

Patuelli, Roberto; Reggiani, Aura; Gorman, Sean; … - In: Networks and Spatial Economics 7 (2007) 4, pp. 315-331

The analysis of complex networks has recently received considerable attention. The work by Albert and Barabási presented a research challenge to network analysis, that is, growth of the network. The present paper offers a network analysis of the spatial commuting network in Germany. First, we...

Vanishing Boycott Impetus: Why and How Consumer Participation in a Boycott Decreases Over Time

Lasarov, Wassili; Hoffmann, Stefan; Orth, Ulrich - In: Journal of Business Ethics 182 (2021) 4, pp. 1129-1154

Media reports that a company behaves in a socially nonresponsible manner frequently result in consumer participation in a boycott. As time goes by, however, the number of consumers participating in the boycott starts dwindling. Yet, little is known on why individual participation in a boycott...

Dynamic Effects on the Stability of International Environmental Agreements

de Zeeuw, Aart - 2005

In terms of the number of signatories, one observes both large and small international environmental agreements. The theoretical literature, based on game theory, discusses different concepts and mechanisms for the stability of coalitions and has reached the conclusion that, under...

A Bugs Life: Competition Among Species Towards the Environment

Bella, Giovanni - 2007

A model of different species competing for the same environment is presented, and possible explanations of peaceful coexistence or rather internecine conflicts are consequently derived. By means of a Lotka-Volterra dynamic system we describe the evolution of two populations (bees and locusts)...

Dollarization dynamics: A comment

Ocampo, Emilio; Cachanosky, Nicolás - 2023

We analyze a recent paper that claims that dollarizing an economy in the presence of a "dollar shortage" will provoke an immediate sharp reduction in real output and welfare. We find many problems with the model that supports this conclusion: confusion about the nature of a dollar shortage and...

Unemployment Insurance Eligibility and the Dynamics of the Labor Market

Zhang, Min - 2009

This thesis examines a number of issues regarding the Mortensen-Pissarides search and matching model’s empirical performance. Chapter 1 documents the volatility puzzle with the Canadian data. The combined data from both Canada and the United States present an additional difficulty. Even if the...
