This paper considers testing that an economic time series follows a martingale difference process. The martingale difference hypothesis has been typically tested using information contained in the second moments of a process, that is, using test statistics based on the sample autocovariances or...

This note provides an alternative perspective for size-corrected power for a test. The advantage of this approach is that it allows the calculation of size-corrected power for bootstrap tests.

This article considers testing that a time series is uncorrelated when it possibly exhibits some form of dependence. Contrary to the currently employed tests that require selecting arbitrary user-chosen numbers to compute the associated tests statistics, we consider a test statistic that is very...

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 Robinson (1991, 1994a) Lagrange Multiplier...

This article addresses statistical inference in models defined by conditional moment restrictions. Our motivation comes from two observations. First, generalized method of moments, which is the most popular methodology for statistical inference for these models, provides a unified methodology...

We characterize the following choice procedure. The decision maker is endowed with a preference and a similarity - a reflexive binary relation over alternatives. In any choice problem she includes in her choice set all options that are similar to her most preferred feasible alternative. Hence an...

Macroeconomists have long been interested in understanding differences in hours worked across countries. Prescott (2004) shows that differences in labor income tax explain the majority of the difference in hours worked between the United States and European countries. In this paper we go one...

We survey and synthesize the political economy literature on dynamic elections in the two traditional settings, spatial preferences and rent-seeking, under perfect and imperfect monitoring of politicians actions. We define the notion of stationary electoral equilibrium, which encompasses...
