EFFICIENT WALD TESTS FOR FRACTIONAL UNIT ROOTS [PDF]
In this article we introduce efficient Wald tests for testing the null hypothesis of unit root against the alternative of fractional unit root. In a local alternative framework, the proposed tests are locally asymptotically equivalent to the optimal ...

German dominance in the European Monetary System: a reprise using robust Wald tests
This study re-examines the German dominance hypothesis in the EMS. A VAR in levels approach is adopted and modified Wald tests, which are robust to cointegration properties of the variables, are used. The findings indicate that, although Germany played a

How Competitive Is Myanmar's Rice Sector? A Comparison of Production Costs and Efficiency
Agribusiness, EarlyView.ABSTRACT This paper analyzes the cost competitiveness of rice production in Myanmar by examining production costs, cost efficiency, and the potential effect of improving cost efficiency on the country's global competitiveness. To achieve this, we conduct a comparative analysis of production costs among major rice‐producing countries and estimate the ...

Agribusiness, EarlyView.ABSTRACT Contract farming is a viable strategy agribusinesses rely on to strengthen coordination across actors in the value chain. However, low contract compliance remains a significant setback to agribusinesses' contract performance in low‐ and middle‐income country context.

Bootstrap Testing in Nonlinear Models [PDF]
When a model is nonlinear, bootstrap testing can be expensive because of the need to perform at least one nonlinear estimation for every bootstrap sample.

Weak Identification Robust Tests for Subvectors Using Implied Probabilities
EntropyThis paper develops tests for hypotheses concerning subvectors of parameters in models defined by moment conditions. It is well known that conventional tests such as Wald, Likelihood-ratio and Score tests tend to over-reject when the identification is ...
