GMM provides a computationally convenient estimation method and the resulting estimator can be shown to be consistent and asymptotically normal under the fairly moderate regularity conditions. It is widely known that the information content in the population moment condition has impacts on the...

In this thesis, we extend Bai and Perron's (1998, Econometrica, pp. 47-78) method fordetecting multiple breaks to nonlinear models. To that end, we consider an unstable univariatenonlinear least squares (NLS) model with a limited number of parameter shifts occurring atunknown dates. In our...

The role played by financial intermediaries and banks in modern economies is undeniably critical. However, explaining their importance in a theoretical general equilibrium framework presents some challenges. If firms and households have unrestricted access to complete financial markets, then at...
