the chechen republic (commonly referred to as chechnya) is a part of vast territory of russian federation that has been a source of contention since collapse of the soviet :union:. identity elements and tattered cultural bonds have strained ties between two nations of chechnya and russia. various aspects of crisis in chechnya have been addressed by many theoretical approaches of international r...

The analysis of land investment and tenure security usually assumes land scarcity. However, some developing countries have communities with land abundance. This article therefore examines the effects of land abundance for investment and tenure security. The paper develops a formal test of land abundance and estimates a system of three simultaneous equations. The empirical analysis uncovers sign...

This study analyzes an optimal investment strategy for information security (IS) for a profit-maximizing online monopoly when it is facing attacks from cyber criminals by considering a network security theoretical model with time-varying characteristics. The intangible profit of security investment is transformed into a measurable sales benefit by using a successful entry ratio that links the r...

this study aimed at identifying critical factors affecting the security of iranian football stadiums and prioritizing them using the analytical hierarchy process (ahp) for future decisions. in the qualitative stage of the study, the main factors affecting the security of iranian football stadiums were identified in 12 semi-structured interviews with experts. in the quantitative stage, 17 expert...

The protection of assets, including IT resources, intellectual property and business processes, against security attacks has become a challenging task for organizations. From an economic perspective, rms need to minimize the probability of a successful security incident or attack while staying within the boundaries of their information security budget in order to optimize their investment strat...

Most articles that discuss the economics of security focus on the use of rational choice decision models for evaluating investment alternatives. However, security investment decisions involve risk and several researchers have noted that risk related decisions often violate the fundamental principles of rational choice decision models. Accordingly, we assert that problems exist with using these ...

China’s pension system is facing a large gap of more than one trillion RMB. The investment efficiency of the social security fund therefore receives widespread attention in academic circles. We collected data of stocks held by the Chinese National Council for Social Security Fund (CNCSSF) from 2004 to 2012 to research the stocks’ investment efficiency, distinguishing between direct investment b...

Let X,, , X, be a sequence of independent and identically distributed random variables with an unknown underlying continuous cumulative distribution function F. Relative to this unknown distribution function suppose one would like to test a null hypothesis concerning the goodness of fit of F to some distribution function using symmetric functions of sample spacings. In some applications the nul...

We devise a model for security investment that reflects dynamic interaction between a defender, who faces uncertainty, and an attacker, who repeatedly targets the weakest link. Using the model, we derive and compare optimal security investment over multiple periods, exploring the delicate balance between proactive and reactive security investment. We show how the best strategy depends on the de...
