The present paper tests for the validity of long-run purchasing power parity (PPP) for the three key currencies of the recent floating exchange rate period, the US dollar, the German mark and the Japanese yen. The novelty of the paper is that the validity of the PPP conditions relating the...

The present paper exploits the idea that empirical estimates of the long-run PPP relationship may compound two distinct influences coming from the behavior of market participants and policy makers when the latter are targeting the exchange rate. This tends to bias tests of long-run PPP against...

This paper develops a model of a representative transition economy to explain the stylised facts of output declines and real exchange rate appreciation in the early stages of transformation. These facts can be explained by supply-side shocks, interest rate liberalisation or a reduction in core...

Recent studies on real exchange rates advocate the use of long samples in order to reveal the low frequency properties of the processes. The present paper contributes to this strand of the literature by exploiting recently released time series for the drachma/sterling rate for the period...

Sovereign bonds are usually priced under the assumption that only the sovereign issuer may be responsible of their repayment. In some cases however, bondholders may legitimately expect to be repaid by more than one agent. For example, when a country breaks-up, successor states may agree to...

This work focuses on the sensitivity of the performance of the moving average (MA) trading rule of technical analysis to changes in the MA length employed. Empirical analysis of daily data from NYSE, the Vienna Stock Exchange (VSE) and the Athens Stock Exchange (ASE) reveal high variability of...

This paper considers an international oligopoly where firms simultaneously choose both the amount of output produced and the proportion of R&D investment to output. The model captures the links between the exchange rate, market power, innovative activity and price, which are important for the...

This paper aims to present the main developments of banking and finance in Albania in a historical perspective. This historical overview might help to better understand not only the great difficulties and obstacles the country faced in the past but also the successes it achieved. It is widely...

The aim of this study is to examine the relationship between banking sector reform and bank performance – measured in terms of efficiency, total factor productivity growth and net interest margin – accounting for the effects through competition and bank risk-taking. To this end, we develop...
