Consider a model in which a consumer faces a lottery with j other people for a prize, so that the probability of winning the prize is 1/(j+1). Now let j be a random variable, determined by the binomial distribution. Specifically, let there be n potential competitors for the consumer in the...

Summary for non-specialistsAs a result of the financial crisis, cyclically corrected indicators have taken on a greater degree of significance and are firmly back at the forefront of economic policy making. This heightened level of policy interest not only reflects the anxiousness of policy...

Econometrics has come into being and grown as a result of the need to set up instruments of investigation and increase of the methods to organize, conduct and manage the economy, and on the other hand, due to the successful statistical and mathematical me

This paper examines the long-run relationship between oil prices and stock market prices of G7 countries by using Robinson (1994a) tests for fractional integration and cointegration instead of the classical approaches. Having found that the unit root null hypothesis cannot be rejected for any...

Due to growing skepticism over the globalisation process across countries, economists in the emerging market economies (EMEs) are anxious to know how the integration of financial markets was associated with the recent global crisis and whether there could be some key lessons for the broader...

The objective of this research is to present some accuracy measures associated to forecast intervals, taken into account the fact that in literature some specific accuracy indicators for this type of prediction have not been proposed yet. For the quarterly inflation rate provided by the National...

We develop a new method, based on the use of polar coordinates, to investigate the existence of moments for instrumental variables and related estimators in the linear regression model. For generalized IV estimators, we obtain familiar results. For JIVE, we obtain the new result that this...

This paper derives asymptotic power functions for Cramer-von Mises (CvM) style tests for conditional moment inequality models in the set identified case. Combined with power results for Kolmogorov-Smirnov (KS) tests, these results can be used to choose the optimal test statistic, weighting...

We consider inference on optimal treatment assignments. Our methods allow for inference on the treatment assignment rule that would be optimal given knowledge of the population treatment effect in a general setting. The procedure uses multiple hypothesis testing methods to determine a subset of...

The bootstrap is a convenient tool for calculating standard errors of the parameters of complicated econometric models. Unfortunately, the fact that these models are complicated often makes the bootstrap extremely slow or even practically infeasible. This paper proposes an alternative to the...
