Existing econometric approaches for studying price discovery presume that the number of markets are small, and their properties become suspect when this restriction is not met. They also require making identifying restrictions and are in many cases not suitable for statistical inference. The...

Abstract: In this paper, we study the small sample properties of the panel data stationarity test of Hadri (2000). We find that the previously suggested moments, that are to be used when standardizing the panel data stationarity test, cause size distortions when samples are small and serial...

This paper proposes new pooled panel unit root tests that are appropriate when the data exhibit cross-sectional dependence that is generated by a single common factor. Using sequential limit arguments, we show that the tests have a limiting normal distribution that is free of nuisance parameters...

Migration has been associated with higher levels of trade. Previous studies interpret this as evidence of migrants’ ability to lower trade costs. Nevertheless, no study has investigated the impact of migrants on firms’ foreign trade. Thus, they fail to both provide evidence on the role that...

Sweden has seen a rise in business R&D-intensities and dependence on exports to make its economy grow since the early 1990s. This paper examines the role of foreign sales in stimulating R&D as compared to a domestic sales effect, and finds, in line with the literature, that R&D rises...

Menu labeling of prepared meals away from home is a policy designed to help consumers make healthier food choices. In this paper, we use a field experiment to analyze if a restaurant benefits from introducing a healthy labeled meal on its menu by experiencing an overall increase in sales. We...

This paper develops two very simple tests for the null hypothesis of no cointegration in panel data. The tests are general enough to allow for heteroskedastic and serially correlated errors, unit specific time trends, cross-sectional dependence and an unknown structural break in both the...

This paper proposes an LM test for the null hypothesis of cointegration that allows for the possibility of multiple structural breaks in both the level and trend of a cointegrated panel regression. The test is general enough to allow for endogenous regressors, serial correlation and an unknown...

In a recent study, Bai (Fixed-Effects Dynamic Panel Models, A Factor Analytical Method. Econometrica 81, 285-314, 2013a) proposes a new factor analytic (FA) method to the estimation of dynamic panel data models, which has the unique and very useful property that it is completely bias-free....

The cross-section average (CA) augmentation approach of Pesaran (2007) and Pesaran et al. (2013), and the principal components-based panel analysis of non-stationarity in idiosyncratic and common components (PANIC) of Bai and Ng (2004, 2010) are among the most popular “second-generation”...
