Abstract
Since the reforms undertaken by policymakers to stop the depreciation of the Tunisian currency have failed, this paper investigates the dynamic of the Tunisian real exchange rate RER). The paper examines the nonlinear behavior of the power party purchase in Tunisia. It also considers whether the RER follows a true long-memory or spurious long-memory process with the presence of shifts. The analysis has two main findings. First, strong evidence of short memory in the presence of structural breaks appears in the Tunisian RER and, second, our results highlight that the presence of structural breaks creates distortions that prevent Tunisian policymakers from reacting to the exchange rate system effectively through central bank intervention. The dynamic of the Tunisian exchange rate is governed by the heterogeneity among investors and policy changes. The presence of multiple regimes in the Tunisian exchange rate implies that monetary policy cannot affect the exchange rate dynamic through central bank interventions. Therefore, this study recommends that Tunisian policymakers follow a market-oriented strategy in making relevant reforms, such as revisiting the weight of the dinar against the euro, to ensure better management of the risks associated with foreign exchange fluctuations.

Notes
We note that the Tunisian currency is anchored against the euro to within 80%.
Other theories aim to explain the dynamics of exchange rates such as the balance of payments and financial globalization.
The structure of fundamentals-based models is similar between studies.
Extensive mathematical research over recent years has focused on important issues in economics and finance such as stock exchanges and foreign currency dynamics.
Canada, Germany, the United Kingdom, France, Italy, Japan, Austria, Belgium, Denmark, the Netherlands, Norway, Sweden, Switzerland, Finland, Greece, Portugal, and Spain.
Under the assumption of spatially separated countries and significant shipping costs.
To discriminate between different models, the authors used out-of-sample forecasting behavior and employed the mean squared error to distinguish between out-of-sample forecasting and sample forecasts.
The major currencies are the Canadian dollar, Japanese Yen, Swiss Franc, Singapore dollar, and the British pound. The less liquid currencies are: Indonesia, South Korea, Malaysia, Philippines, and Thailand.
In this analysis, our objective is not to address all tests used in the literature to detect long memory or structural breaks; we retain the main tests used in existing studies.
For consistency and asymptotic normality see assumptions (1–5) and (10–50) in Shimotsu and Phillips (2005), pp. 1893–1897.

A commando army was formed by dozens of men who were conscripted in Libya. This act caused France, the United States, and Morocco to send warships and planes to suppress the insurgency. In response to Libyan involvement, Tunisian President Bourguiba cancelled diplomatic relations with Libya.
The devaluation of the dinar reached a nominal level of 45% and a real level of 25% in 1988.
Here, we select ESTAR models among various threshold models such as SETAR and TAR. Our motivation behind this choice is that the exchange rate dynamic typically occurs smoothly because it depends on the fundamentals. Furthermore, this model is the most used in previous literature.
