Sommario/riassunto |
|
The classical Pontryagin maximum principle (addressed to deterministic |

|
|
|
|
|
|
|
|
|
|
|
finite dimensional control systems) is one of the three milestones in modern control theory. The corresponding theory is by now well-developed in the deterministic infinite dimensional setting and for the stochastic differential equations. However, very little is known about the same problem but for controlled stochastic (infinite dimensional) evolution equations when the diffusion term contains the control variables and the control domains are allowed to be non-convex. Indeed, it is one of the longstanding unsolved problems in stochastic control theory to establish the Pontryagintype maximum principle for this kind of general control systems: this book aims to give a solution to this problem. This book will be useful for both beginners and experts who are interested in optimal control theory for stochastic evolution equations. |

Sommario/riassunto |
|
In this paper, we consider incidences of arrears to the IMF, focusing on protracted arrears cases and attempt to identify determinants of their occurrence. We use narrative and formal methods. In addition, we analyze determinants of the duration of arrears. We find that previous arrears, reserves coverage, and institutional quality are among the main determinants of arrears. In addition, we identify a role for political developments, including civil unrest, which make arrears more likely to arise and to last longer. We conclude that improved macroeconomic conditions and turnaround of political fortunes would help to clear the currently remaining protracted arrears cases. |
