This paper studies the effect of real effective exchange rate (REER) volatility on economic growth as well as the euro’s effect on REER volatility. We first show that, after a plausible endogeneity correction, REER volatility is negatively associated with growth in a 1980~2011 panel of OECD countries. One standard deviation volatility decrease is associated with about two percentage points (0.8...
This paper assesses liquidity conditions in foreign exchange (FX) spot and derivatives markets using intra-day data against the background of FX dealers’ response to recent regulatory changes. Given that FX swap markets are by some measures even deeper that the spot market, an assessment of FX liquidity requires taking such instruments into account. We find that spot and swap market liquidity i...
We examine empirically the conjecture that limits to speculation in the foreign exchange market may induce nonlinearities in the spot-forward relationship and in the process driving the deviations from the uncovered interest rate parity (UIP) condition. Our empirical results provide strong evidence of important nonlinearities which are consistent with a model of deviations from UIP with two ext...
This paper contributes to the existing literature on dating currency crisis in three ways. First, we combine the Monte Carlo simulation with a modified Hill’s estimator method to obtain more robust results and efficiently deal with bias variance tradeoff in identifying extreme values. Second, we propose a systematic way to choose the reference country in building the Exchange Market Pressure in...
Article history: Received 15 May 2014 Received in revised form 14 January 2015 Accepted 14 January 2015 Available online 22 January 2015 This paper estimates the degree of persistence of 16 long-horizon real exchange rates relative to the US dollar. We use nonparametric operational algorithms by El-Gamal and Ryu (2006) for general nonlinear models based on two statistical notions: the short mem...
Today many argue that there appears to be an epidemic case of “fear of floating”. Some have further claimed that credible inflation targeting – a popular regime choice today – and fear of floating are identical regimes. This paper takes a different view. We modify Calvo and Reinhart’s (2002) approach to analyze the behavior of exchange rates, reserves, interest rates and inflation across 88 exc...
This paper proposes a di¤erent empirical approach to estimate the UIP by analyzing a large number of cross-country bilateral exchange rates using cross-section analysis. Di¤erent from conventional time-series UIP, cross-sectional UIP is examined with single equation estimation and panel regression model estimation. The exchange rates analyzed here include a broad spectrum of countries: develope...
We employ a multivariate BEKK GARCH model which allows news to affect conditional volatility in an asymmetric manner. The asymmetric model outperforms the standard symmetric model, implying that efficient financial decision makers should not treat good and bad news as homogenous. We estimate the conditional variance and covariance of the Japanese yen, Swiss franc and British pound vis-à-vis the...
انحراف نرخ حقیقی ارز از مقدار تعادلی آن یکی از مباحث مناقشهآمیز در اقتصاد ایران است. از یک طرف، با به چالش کشیدن نظریهی برابری قدرت خرید این ایده مطرح است که باید دولت از کاهش ارزش واقعی ریال جلوگیری کرده و مانع انتقال نرخ ارز به تورم شود. از طرف دیگر، آسیبهایی که انحراف نرخ ارز بر تولید داخلی، صادرات غیرنفتی و اشتغال دارد، باعث میشود از آن به عنوان پدیده ای نامطلوب یاد شود. در این راستا، پ...
کنترل تورم همواره به عنوان یکی از مهمترین اهداف اقتصاد کلان در هر کشوری می باشد. تورم بالا و اثرات مخرب آن بر رفاه مردم، موضوعی است که سیاستگذاران اقتصادی و اجتماعی همواره سعی می کنند با استفاده از ابزارهای مناسب، اثرات آن را تعدیل و کنترل نمایند. تورم در نظام سلامت به موارد مختلفی از قبیل سالمند شدن جمعیت، مسائل بیمه ای (پوشش ناقص، مدیریت ضعیف و...)، بهره وری پایین (نیروی انسانی شاغل در بخش سل...
