This paper conducts the goodness of fit test of Bartlett (1954) on the stock prices of 12 countries during the period from January 1921 to December 1930 to examine the market efficiency hypothesis. The market efficiency hypothesis is not rejected for most European countries, but it is rejected...

The performance of the Phillips and Perron unit root tests is examined using the optimal bandwidth selection procedure of Andrews and the pre-whitening procedure of Andrews and Monahan. It has been shown that they do not make significant improvements over the tests using fixed truncation lags.

This paper develops new tests of the unit root hypothesis based on instrumental variables estimation. The tests are asymptotically valid in the presence of moving average errors and they are quite accurate in finite samples. They are more powerful against stationary alternatives than other tests...

The influential and controversial paper by Reinhart and Rogoff (2010) triggered a debate on the effects of public debt on economic growth. Subsequent papers provide more convincing results. However, one of the key assumptions implied in these studies is that lower economic growth is spurred by...

In this paper, we test for asymmetric adjustments in the spread of the U.S. prime lending rate and 3-month certificate of deposit rate. In doing so, we extend the pioneering threshold unit root tests of Enders and Granger (1998) to more flexible models where the deterministic terms and short-run...

This paper demonstrates the significance of culture in examining the relationship between income and the environment. Specifically, we examine the relationship among scores on the Environmental Sustainability Index of the World Economic Forum and the four dimensions of national culture proposed...
