The study here reviews the institutional structure of the Sudanese government. Truly, though it is stigmatized as totalitarian, the structure is phenotypically perfect. Ministry of Ministries council is supposed to cater for analyzing data concerning ministries performance, drawing strategic...

We analyze how financial experts influence asset prices in a sequential trading model. In the model, an expert of unknown ability sends a report about asset values to traders, who then observe a signal about the expert's type. All information about the expert's ability is private to traders and...

By choosing whether or not to follow a financial expert's advice, a privately informed trader implicitly screens the ability of this expert. We explore the performance of the resulting feedback mechanism. In the medium run, feedback may altogether break down, enabling experts of low ability to...

Within the insurance process, the person who insures as well as the person who wishes to buy an insurance policy must control well enough the communication techniques. In deed, the insurance is grounded on communication. Various scientific researches showed that most people involved in a...

We present an experiment in which extrinsic information (signals) may generate sunspot equilibria. The underlying coordination game has a unique symmetric non-sunspot equilibrium, which is also risk-dominant. Other equilibria can be ordered according to risk dominance. We compare treatments with...

We consider a model of evolution with mutations as in Kandori et al. (1993) [Kandori, M., Mailath, G.J., Rob, R., 1993. Learning, mutation, and long run equilibria in games. Econometrica 61, 29–56], where agents follow best-response decision rules as in Sandholm (1998) [Sandholm, W., 1998....

We consider partial bandwagon properties in the context of coordination games to capture the idea of weak network externalities. We then study a local interactions model where agents play a coordination game following a noisy best-reply process. We show that globally pairwise risk dominant...

My thesis consists of three essays that investigate strategic interactions between individuals engaging in risky collective action in uncertain environments. The first essay analyzes a broad class of incomplete information coordination games with a wide range of applications in economics and...

Economic growth is reflected in SDG8 of the sustainable development goals. Financial stability has been identified as a factor promoting economic growth. However, there is little evidence on the effect of financial stability on economic growth in Nigeria. This study empirically examines the...
