We consider consistent tests for stochastic dominance efficiency at any order of a given portfolio with respect to all possible portfolios constructed from a set of assets. We justify block bootstrap approaches to achieve valid inference in a time series setting. The test statistics are computed...

This paper investigates why all-inclusive travel packages are offered at some hotels but not at others. By using the theory of transaction cost, it is argued that all-inclusive contracts mitigate a hold-up problem and that the severity of this problem varies with regards to the hotel's distance...

We propose a class of new robust GMM tests for endogenous structural breaks. The tests are based on supremum and average statistics derived from robust GMM estimators with a bounded influence function. They imply a bounded linearized asymptotic bias of size and power under local model...

A growing body of evidence suggests a link between climate and conflict. In contrast, the link between climate and cooperation remains much less investigated, although it has been studied in the context of transboundary river basins. Even for transboundary waters, however, earlier results have...

This paper brings together identification and forecasting in a positive econometric analysis of policy. We contend that a broad range of important policy questions is consistent with the existing policy process and is not subject to Lucas's critique. We analyze the economics of "business as...

The objective of this paper is to identify the impact of public and private agriculturalresearch on multi-output multi-input profit maximizing decisions of Midwestern farmers. The mainhypothesis is that investments in public and private R&D shift outward the supply curves for cropand livestock...
