This paper presents a dynamic international trade model based on monopolistic competition, where observed intra-industry differences at a given point in time reflect different stages of the firm’s life cycle. New product varieties of still higher quality enter the market every period rendering...

We introduce and investigate some properties of a class of nonlinear time series models based on the moving sample quantiles in the autoregressive data generating process. We derive a test fit to detect this type of nonlinearity. Using the daily realized volatility data of Standard & Poor’s...

There is little evidence on the efficiency of the early stage of the capital market in transition countries, although market structure developments and the learning process could define the framework for efficient markets. The article tries to find out whether financial markets are efficient in...

In a series of articles of the journal Applied Economics there was an extensive debate on the Balance-of-Payments (BOP)-constrained growth model and its testing. This led to a single-equation-based test for the necessary condition of the BOP-constrained growth model that the BOP constraint...

We propose a test for the evaluation of statistical acceptability of a functional constraint which is imposed on parameters in the mixed data sampling regressions. The asymptotic behavior of the test statistic is characterized and a few other extensions are discussed.

This paper presents a balance-of-payments (BOP) constrained growth analysis of the long-run growth process in the Central and Eastern European (CEE) countries during the recovery period of transition (1995-2004). The paper tests the BOP-constrained growth model, based on the specification of a...

An increasing variety of data frequencies available in economics, finance, etc. gives rise to a question how to build and estimate a regression model with variables observed at different frequencies. In a unifying framework of ("m,d")-aggregation we consider various approaches by discussing some...

This paper presents a simple condition for optimal asymmetric labour (capital) taxation/subsidization in a two-sector model with logarithmic utilities and Cobb-Douglas production functions, linked to demographic factors: fertility rate and longevity. The paper shows that depending on parameter...

Many European Union states have adjusted pension benefits or reformed the pension system in reaction to the recent economic crisis, while other member states have postponed this type of adjustments. In this paper we study to what extent countries that responded quickly to the crisis are harmed...
