Economic sanctions are associated with various forms of trade barriers and restriction on financial transactions. Among the most influential sanctions on Iran's oil export and central bank sanctions are noted that their Aims to reduce Iran's oil revenues and Devaluation...

Defending Against Speculative Attacks: Reputation, Learning, and Coordination

How does the central bank’s incentive to build a reputation affect speculators’ ability to coordinate and the likelihood of the devaluation outcome during speculative currency crises? What role does market information play in speculators’ coordination and the central bank’s reputation building? I address these questions in a dynamic regime change game that highlights the interaction between the...

SOM-based data analysis of speculative attacks' real effects

In some cases, currency crises are followed by strong recessions (e.g., recent Asian and Argentinean crises), but in other cases they are not. This paper uses Self-Organizing Maps (SOM) to search for meaningful associations between speculative attacks’ real effects and 28 variables that characterize the economic, financial, legal, and socio-political structure of the country at the onset of the...

Spectre Attacks: Exploiting Speculative Execution

Modern processors use branch prediction and speculative execution to maximize performance. For example, if the destination of a branch depends on a memory value that is in the process of being read, CPUs will try guess the destination and attempt to execute ahead. When the memory value finally arrives, the CPU either discards or commits the speculative computation. Speculative logic is unfaithf...
