The role of structural breaks in long spans of ex-post real interest rates for ten industrialized countries is studied. First, the persistence of the real interest is assessed with newly proposed low-frequency tests of M¨uller and Watson (2008). Second, the test of Leybourne et al. (2007) for a...

The purpose of this article is to introduce an original macro code written in SAS 4GL. This macro is used to automate the process of forecasting with dynamic factor analysis. Automation of the process helps to save significant amounts of time and effort for the researcher. It also enables to...

Data revision is defined as an adjustment published after the initial announcement had been made; it may reflect rectification of errors, availability of new information, etc. When economists use a database, they may not even be aware that some of the values have been revised, perhaps repeatedly,...

Financial crises, booms and busts are an inherent part of the capitalist system. The current financial crisis that began in 2007 has reignited the debate about the causes and consequences of previous economic downturns. While some look at the differences among crises, both historical and as...

This paper introduces the concept of range-dependent utility. Instead of reference dependence which evaluates outcomes relative to some reference point, we postulate dependence on a given lottery (set of lotteries) outcomes range. In this way the decision maker is a fully rational expected...

This paper evaluates information content of survey data by the means of entropy and dissimilarity measures. Similarities between a priori information (expectations) and a posteriori information (realizations) are assessed for four variables originating from Polish business tendency survey and...

Poland has historically demonstrated exceptional resiliency in the face of change. This paper examines how Poland coped with huge structural realignments from the rise of Solidarity until the present, seeking to provide an objective analysis of Poland’s evolution of trade structures while it...

To date there does not exist one a generally acceptable measure or index of Specialization in International Trade. The intention of this article is to evaluate the exogenous dismissal probability for a certain worker depending on her characteristics for the Polish labor market. To model this...

Economic theory typically predicts that productivity should increase when a firm’s market is expanding since the benefits of reducing costs are higher when spread across a larger market. On the other hand there is a strong line of research stressing the positive impact of increasing...

Discrete-time ARMA processes can be placed in a one-to-one correspondence with a set of continuous-time processes that are bounded in frequency by the Nyquist value of ð radians per sample period. It is well known that, if data are sampled from a continuous process of which the maximum...
