Islamic banking is a growing phenomenon which came into existence to satisfy the financial needs of devout Muslims who observe the prohibition of interest-based transactions. Many economists have studied the macroeconomic properties of this institution in the framework of an isolated and ideal...

The EC (Estimation-Classification) estimator, and its companion EC-algorithm, were introduced in El- Gamal and Grether (1995), and their properties further analyzed in El-Gamal and Grether (1996). The purpose of EC estimation is to uncover heterogeneity in panel data models in a manner which is...

We propose a set of algorithms for testing the ergodicity of empirical time series, without reliance on a specific parametric framework. It is shown that the resulting test asymptotically obtains the correct size for stationary and nonstationary processes, and maximal power against non-ergodic...

Extremum estimation is typically an ad hoc semi-parametric estimation procedure which is only justified on the basis of the asymptotic properties of the estimators. For a fixed finite data set, consider a large number of investigations using different extremum estimators to estimate the same...

We extend Armstrong’s result on exclusion in multi-dimensional screening models in two key ways, providing support for the view that this result holds true in a large class of models and is applicable to many different markets. First, we relax the strong technical assumptions he imposed on...

We consider a team production problem in which the principal observes only the group output and not individual effort and in which the principal can only penalize an agent for poor performance if she has verifiable evidence that the agent in question did not fulfill his job assignment. In this...
