This paper investigates non-linearity in spatial processes models and allows for a gradual regime-switching structure in the form of a smooth transition autoregressive process. Until now, applications of the smooth transition autoregressive (STAR) model have been largely confined to the time...

Aim of this paper is to study whether and how the firm’s decision to outsource production activities affects its technological performance. In particular, we look at how the alignment between the firm’s governance strategy and the underlying attributes of the transactions affects the capacity...

The recently examined durability-asymmetry hypothesis of Cook (1999) is re-evaluated using the diagnostic tests of time deformation proposed by Stock (1987, 1988). An application of these tests to disaggregated data on U.S. consumers’ expenditure provides further support for this hypothesis,...

The efficient market hypothesis (EMH) is tested in the case of the AthensStock Exchange (ASE) after the introduction of the euro. The underlyingassumption is that stock prices would be more transparent; their performanceeasier to compare; the exchange rate risk eliminated and as a result we...

This study investigates exchange rate movements in the Exchange Rate Mechanism (ERM) of the European Monetary System (EMS) and in the Exchange Rate Mechanism II (ERM-II). On the basis of Bessec (2003), we set up a three-regime self-exciting threshold autoregressive model (SETAR) with a...
