5. Tattaunawa & Abubuwan Da Ake Nufi

Sakamakon maras amfani yana da mahimmanci. Suna nuna cewa halayen tsarin Yankin 'Yanci na Filin Jirgin Sama na Atatürk na Istanbul—irinsu kayan shiga ba tare da haraji ba, kwangilolin dogon lokaci da aka ƙididdige su cikin kuɗaɗen da suka daɗe, da kuma mai da hankali kan sake fitarwa—suna haifar da kariya daga sauyin farashin canjin kuɗi. Wannan yana nuna cewa matakan siyasa da ke niyyar kai wa tattalin arziƙin gabaɗaya hari ta hanyar daidaita kuɗi na iya samun ƙaramin tasiri kai tsaye ga aikin yankin 'yanci.

6. Ƙarshe

Wannan binciken ya ƙarasa da cewa hanyoyin ciniki a Yankin 'Yanci na Filin Jirgin Sama na Atatürk na Istanbul ba su da tasiri sosai daga sauye-sauyen farashin canjin kuɗi a lokacin 2003-2016.

7. Nazari na Asali & Sharhin Kwararru

Fahimta ta Asali: Demirtaş ya ba da sakamako mai ban mamaki amma mai ƙarfi a zahiri: babban ma'auni na tattalin arziki—farashin canjin kuɗi—ba shi da tasiri a cikin takamaiman yanki na yankin 'yanci na Turkiyya. Wannan ba kawai sabon abu ne na ƙididdiga ba; shaida ce ta ingantaccen yanki na tattalin arziki da ya raba cinikin aiki daga sauyin kuɗin ƙasa.

Hanyar Hankali: Ƙarfin binciken yana cikin ƙaƙƙarfan hanyarsa. Ba kawai ya gudanar da alaƙa mai sauƙi ba. Ci gaba daga gwaje-gwajen tushen raka'a (kafa tsarin I(1)) zuwa nazarin haɗin kai (neman alaƙar dogon lokaci) kuma a ƙarshe zuwa gwajin sanadin Toda-Yamamoto (ingantaccen binciken tasiri) ya haifar da sarkar shaida mai ƙarfi. "Sakamakon maras amfani" da ya yi daidai a cikin gwaje-gwaje daban-daban ya sa ƙarshen rashin hankali ya fi aminci fiye da ƙididdiga ɗaya mara kyau.

Ƙarfafawa & Kurakurai: Babban ƙarfinsa shine tsarinsa na zahiri mai tsabta, mai da hankali akan bayanai na musamman. Duk da haka, nazarin yana da guraben gani.

Fahimta Mai Aiki: Ga masu tsara manufofi, wannan binciken ya zama takobi mai kaifi biyu. Labari mai dadi: yankunan 'yanci na iya zama masu samun kuɗin waje amintattu ko da a lokacin rikicin kuɗi. Mummunan labari: yin amfani da farashin canjin kuɗi a matsayin kayan aiki don haɓaka ayyukan yankin 'yanci kai tsaye ba shi da amfani. Ainihin ma'auni shine inganta fa'idodin tsarin yankin—dabarun kayan aiki, sauƙin ƙa'ida, da haɗin kai—abubuwan da wannan binciken ya nuna amma bai auna ba. Ga masu saka hannun jari, saƙon a bayyane yake: Yankin 'Yanci na Filin Jirgin Sama na Atatürk na Istanbul ya ba da kariya daga haɗarin kuɗi. Babbar tambaya ga rabon jari na gaba ita ce ko wannan rabuwar tsarin ya kasance cikakke a ƙarƙashin tsarin tattalin arzikin Turkiyya na yanzu.

8. Cikakkun Bayanai na Fasaha & Tsarin Lissafi

$Y_t = c + A_1Y_{t-1} + A_2Y_{t-2} + ... + A_pY_{t-p} + \epsilon_t$

inda $Y_t = [\text{FZ_EX}_t, \text{FZ_IM}_t, \text{EXR}_t]'$ shine vector na ma'auni na ciki, $c$ shine vector na madaidaici, $A_i$ matrices ne na ƙididdiga, kuma $\epsilon_t$ vector ne na kurakuran kuskuren farin sauti.

Gwajin Haɗin Kai na Johansen ya dogara ne akan ƙididdiga na:

$\Delta Y_t = \Pi Y_{t-1} + \sum_{i=1}^{p-1} \Gamma_i \Delta Y_{t-i} + \epsilon_t$

inda $\Pi = \alpha \beta'$. Gwajin yana bincika matsayi ($r$) na matrix $\Pi$. Matsayi na sifili yana nuna babu haɗin kai.

4. Nazarin Girman Manufa: Yi amfani da hanyar nazarin abubuwan da suka faru ko Tsarin VAR na Tsari (SVAR) don nazarin tasirin takamaiman canje-canje a cikin ƙa'idar yankin 'yanci ko manufar cinikin ƙasa, maimakon ci gaba da motsin farashin canjin kuɗi.
5. Tasiri na Gaske vs. Suna: Bincika ko farashin canjin kuɗi na gaske masu tasiri (REER), waɗanda ke lissafin bambance-bambancen hauhawar farashin kayayyaki, suna da wani tasiri, saboda sun fi nuna gasar.
