The European integration process has removed barriers to trade within Europe. We analyze which integration step has most profoundly influenced the trending behavior of export openness. We endogenously determine the single most decisive break in the trend, account for strong cross-country...

The recent global financial tsunami has had economic consequences that have not been witnessed since the Great Depression. But while some countries suffered a particularly large contraction in economic activity on top of a system-wide banking and currency collapse, others came off relatively...

This paper proposes a model that simultaneously captures long memory and structural breaks. We model structural breaks through irreversible Markov switching or so-called change-point dynamics. The parameters subject to structural breaks and the unobserved states which determine the position of...

One of the most infl?uential research ?fields in econometrics over the past decades concerns unit root testing in economic time series. In macro-economics much of the interest in the area originate from the fact that when unit roots are present, then shocks to the time series processes have a...

Fractionally integrated processes have become a standard class of models to describe the long memory features of economic and financial time series data. However, it has been demonstrated in numerous studies that structural break processes and non-linear features can often be confused as being...

This paper deals with the possibility of changing persistence in European real effective exchange rates as initially analyzed by Gadea and Gracia (2009). By applying a CUSUM of squares-based test for constant versus changing persistence with desirable statistical properties, an OECD data set is...

This research points to the serious problem of potentially misspecified alternative hypotheses when testing for unit roots in real exchange rates. We apply a popular unit root test against nonlinear ESTAR and develop a Markov Switching unit root test. The empirical power of these tests against...

This paper presents a family of simple nonparametric unit root tests indexed by one parameter, d, and containing Breitung’s (2002) test as the special case d = 1. It is shown that (i) each member of the family with d 0 is consistent, (ii) the asymptotic distribution depends on d, and thus...

We estimate long-run consumption-based asset pricing models using a comprehensive set of international test assets, including broad equity market portfolios, international value/growth portfolios, and international bond portfolios. We find that differences in returns across assets within a...

This paper builds a dynamic general equilibrium trade model, in which heterogeneous intermediate goods are produced and traded in a Melitz (2003) type sector. These intermediate goods are used in the production of a final good, which can be used for consumption, capital accumulation, or...
