Item Open Access Calendar anomalies in the Turkish foreign exchange markets(Routledge, 2003) Aydoğan, K.; Booth, G. G.This paper investigates calendar anomalies in the Turkish foreign exchange markets during 1986-1994 period. Changes in the free market and official daily exchange rates between the Turkish lira (TL) and US dollar (USD) and the German mark (DM) are examined for empirical regularities on different days of the week, around the turn of the month and before holidays. The findings reveal that free market rates exhibit day-of-the-week and week-of-month effects. In addition free market DM returns display a holiday anomaly. These calendar anomalies are explained by cash disbursement patterns, together with currency substitution in the economy. The impact of treasury auctions and banks' management of liquidity on day-of- the-week effect is also discussed.Item Open Access Does foreign direct investment promote growth? Exploring the role of financial markets on linkages(Elsevier BV, 2010) Alfaro, L.; Chanda, A.; Ozcan, S. K.; Sayek, S.Do multinational companies generate positive externalities for the host country? The evidence so far is mixed varying from beneficial to detrimental effects of foreign direct investment (FDI) on growth, with many studies that find no effect. In order to provide an explanation for this empirical ambiguity, we formalize a mechanism that emphasizes the role of local financial markets in enabling FDI to promote growth through backward linkages. Using realistic parameter values, we quantify the response of growth to FDI and show that an increase in the share of FDI leads to higher additional growth in financially developed economies relative to financially under-developed ones. © 2009 Elsevier B.V.

Y.; Özlale, Ü.; Şahinbeyoǧlu, G.The reported study has two purposes: first, it attempts to improve the literature on foreign exchange interventions of the central banks for the emerging market economies, an area not previously studied in detail. The Turkish economy in the post-crisis period constitutes a good example in this context. Second, it proposes a new methodology, a time-varying parameter model, to analyse the effectiveness of the foreign exchange interventions. When the results from such an exercise are compared with those obtained from an event-study analysis, it is found that purchase-based interventions seem to be successful, especially after stabilization of the financial markets. In that sense, an asymmetry is detected regarding the effectiveness of interventions. Concerning the relationship between interest rates and exchange rates, it is found that the uncovered interest rate parity condition operates in an unconventional way, supporting the views put forward by recent emerging markets literature. © 2006 Taylor & Francis.Item Open Access FDI, productivity and financial development(Wiley-Blackwell Publishing Ltd., 2009) Alfaro, L.; Ozcan, S. K.; Sayek, S.This paper examines the effect of foreign direct investment (FDI) on growth by focusing on the complementarities between FDI inflows and financial markets. In our earlier work, we found that FDI is beneficial for growth only if the host country has well-developed financial institutions. In this paper, we investigate whether this effect operates through factor accumulation and/or improvements in total factor productivity (TFP). Factor accumulation - physical and human capital - does not seem to be the main channel through which countries benefit from FDI. Instead, we find that countries with well-developed financial markets gain significantly from FDI via TFP improvements. These results are consistent with the recent findings in the growth literature that shows the important role of TFP over factors in explaining cross-country income differences. © 2009 The Authors Journal compilation © 2009 Blackwell Publishing Ltd.Item Open Access The impact of inflation uncertainty on interest rates in the UK(Wiley-Blackwell Publishing Ltd., 1999) Berument, HakanThis paper assesses the effect of expected inflation and inflation risk on interest rates within the Fisher hypothesis framework. Autoregressive Conditional Heteroscedastic models are used to estimate the conditional variability of inflation as a proxy for risk. With the UK quarterly data from 1958:4 to 1994:4, we found that both the expected inflation and the conditional variability of inflation positively affect the UK three-month Treasury-bill rate.Item Open Access Intermediation spread, bank supervision, and financial stability(World Scientific Publishing, 2010) Özyıldırım, SüheylaThis paper models the effect of bank competition and deposit insurance premiums on the spread between lending and deposit rates. In developing economies, low spreads do not always indicate bank efficiency; they may be the result of high risk taking. This paper shows that imposing upper and lower limits on banks' spreads and adjusting deposit insurance premiums when violation of these limits occurs leads to a more stable but relatively large intermediation costs. In developing economies, such an outcome would be considered more desirable because it insulates existing financial intermediaries and investors against macroeconomic disturbances.Item Open Access The missing link between inflation uncertainty and interest rates(Wiley-Blackwell Publishing Ltd., 2005) Berument, Hakan; Kilinc, Z.; Ozlale, U.In the literature, there is no consensus about the direction of the effects of inflation uncertainty on interest rates. This paper states that such a result may stem from differentiation in the sources of the uncertainties and analyzes the effects of different types of inflation uncertainties on a set of interest rates for the UK within an interest rate rule framework. Three types of inflation uncertainties - impulse uncertainty, structural uncertainty and steady-state uncertainty - are derived by using a time-varying parameter model with a Generalized Autoregressive Conditional Heteroskedasticity specification. It is shown that the impulse uncertainty is positively and the structural uncertainty is negatively correlated with the interest rates. Moreover, these two uncertainties are important to explain short-term interest rates for the period of inflation targeting era. However, this time, the impulse uncertainty is negatively and the structural uncertainty is positively correlated with the overnight interbank interest rates, which is consistent with the general characteristic of the inflation targeting regimes. Lastly, the evidence concerning the effect of the steady-state inflation uncertainty on interest rates is not conclusive. © Scottish Economic Society 2005.Item Open Access Mixed-integer second-order cone programming for lower hedging of American contingent claims in incomplete markets(2013) Pınar, M. Ç.We describe a challenging class of large mixed-integer second-order cone programming models which arise in computing the maximum price that a buyer is willing to disburse to acquire an American contingent claim in an incomplete financial market with no arbitrage opportunity. Taking the viewpoint of an investor who is willing to allow a controlled amount of risk by replacing the classical no-arbitrage assumption with a "no good-deal assumption" defined using an arbitrage-adjusted Sharpe ratio criterion we formulate the problem of computing the pricing and hedging of an American option in a financial market described by a multi-period, discrete-time, finite-state scenario tree as a large-scale mixed-integer conic optimization problem. We report computational results with off-the-shelf mixed-integer conic optimization software.Item Open Access Monetary transmission mechanism in Turkey under the monetary conditions index: an alternative policy rule(Routledge, 2004) Us, V.This study analyses monetary transmission mechanism in Turkey using a small structural macroeconomic model. The core equations of the model consist of aggregate demand, wage-price setting, uncovered interest rate parity, foreign sector and a monetary policy rule. The aim of the paper is to analyse the disinflation path, the output gap, the output level, the exchange rate and the interest rate, and also the output-inflation variance frontier of the economy under various scenarios. The first scenario assumes that a standard Taylor rule is implemented as the policy rule. In the alternative scenario, instead of the standard Taylor rule, the MCI, Monetary Conditions Index - combination of the changes in the short-term real interest rate and in the real effective exchange rate in a single variable - is used as a policy instrument. The results indicate that the economy stabilizes much more quickly and shows significantly less volatility under this new setting. Therefore, the paper concludes that the policymakers should consider using MCI as an instrument when conducting monetary policy. © 2004 Taylor and Francis Ltd.Item Open Access Money demand, the Cagan model, testing rational expectations vs adaptive expectations: the case of Turkey(Springer, 1999) Metin, K.; Muslu, I.This paper estimates the Cagan type demand for money function for Turkish economy during the period 1986:1-1995:3 and tests whether Cagan's specification fits the Turkish data using an econometric technique assuming that forecasting errors are stationary. This paper also tests the hypothesis that monetary policy was implemented in aiming to maximize the inflation tax revenue. Finally, the Cagan model is estimated with the additional assumption of rational expectations for Turkey for the considered period.Item Open Access Optimal versus adequate level of international reserves: evidence for Turkey(Routledge, 2005) Ozyildirim, S.; Yaman, B.The determination of international reserve balance for emerging economies is part of the efforts to strengthen the immunity of these economies to crises. However, there is still evidence on crises even for the countries with large foreign reserves. It has usually been experienced that the countries with greatest need for reserves economize more than others on their holdings since they might underestimate the cost of crisis. In this study, the official international reserves of Turkey are tested against optimality and adequacy. During 1988-2002, the actual reserves fell short of both the optimal and the adequate levels. They are only optimal when the expected cumulative contraction is about 5.2% of real GDP under crisis. However, early evidence from emerging economies and Turkey show that crises hit more heavily. Hence, it is found that the current financial structure in Turkey such as the absence of capital controls and a highly dollarized banking system necessitates more foreign reserves for preventing any future economic and/or financial shocks.Item Open Access Patterns of financial capital flows and accumulation in the post-1990 Turkish economy(Routledge, 2003) Biçer, F. G.; Yeldan, E.The purpose of this paper is twofold: using time series econometrics, we first investigate the determinants of short-term foreign capital inflows for Turkey following its capital account liberalization in 1989. We next investigate the changing nature of the private investment function under post-capital account liberalization and deduce hypotheses on its correlation with capital inflows and the key macroeconomic prices, such as the exchange rate, the real rate of interest, and real wages. Our results suggest that financial capital inflows have a significant negative correlation with the industrial production index and trade openness, and are positively correlated with real currency appreciation. Fixed private investment was found to have an inconclusive relationship with financial capital inflows. Real wage costs were observed to carry a significant negative relationship with private investment, indicating that at a time of currency appreciation, investors had to rely on declining wage costs in order to keep their export competitiveness. Under the volatile and uncertain conditions of speculation-driven investment patterns, the downward flexibility of real wages has to be seen as a concomitant factor of the post-financial liberalization episodes.Item Open Access Potential information and target variables for UK monetary policy(Routledge, 1998) Berument, Hakan; Froyen, R. T.The relationship between traditional monetary policy goal variables (nominal GDP, real GPD and the inflation rate) and a number of financial market variables is investigated. The question examined is which if any of these financial market variables (monetary aggregates, interest rates and interest rate spreads) are potentially useful as either information variables or intermediate targets. While the implications concerning the usefulness of the financial variables considered are pessimistic concerning nominal GDP, more robust relationships are found for real GDP and inflation. The latter finding is of interest given the current UK monetary policy strategy of inflation targeting. Our results are, however, more supportive of the usefulness of several financial variables as information variables than as intermediate targets.Item Open Access Sources of volatility in stock returns in emerging markets(Routledge, 2005) Caner, S.; Önder, Z.In this study, the short-term fluctuations in the monthly returns on composite indexes of 17 emerging markets affected by the financial crises in the late 1990s and 2000 are decomposed with vector autoregressive estimates. The results are compared to the behaviour of variation in returns in developed markets. Three different models are estimated for each market. Due to first order autocorrelations, lagged returns contribute significantly to return volatility in emerging markets. Decomposition of variances indicates that dividend yield and interest rate are determining factors of volatility, but at varying degrees in different emerging markets. However, the role of dividend yield is not as strong as it is in the developed markets as efficient markets hypothesis would imply. In some cases, exchange rates significantly influence market volatility. Fluctuations in the world portfolio return have a small effect on return volatility in national markets. However, there are significant differences across all emerging markets that point to differences in market structures and particular conditions in each country. Significant contributions of interest rates, exchange rates and inflation imply the role of monetary and fiscal policy as precedents of financial crises.Item Open Access The technical inefficiency effects of Turkish banks after financial liberalization(Wiley-Blackwell Publishing Ltd., 2005) Demir, N.; Mahmud, S. F.; Babuscu, S.The banking sector in Turkey has grown significantly over the last two decades of financial liberalization. One of the aims of the financial liberalization was to improve efficiency through restructuring programs including the privatization of state banks and the encouragement of mergers. In this paper we identify key factors determining the technical efficiency differentials among Turkish commercial banks in the pre-and post-liberalization periods, using the technical inefficiency effects model. We found that loan quality, size, ownership of the banks, and profitability have a positive and significant impact on the technical efficiencies of banks. The results warrant implementation of effective regulatory measures to improve the quality of the earning assets of commercial banks. Furthermore, steps by the government to encourage acquisitions or mergers for private banks and the privatization of state-owned banks seem to be consistent in improving the overall efficiency of commercial banking in Turkey.Item Open Access Time-varying long range dependence in market returns of FEAS members(Elsevier, 2013) Sensoy, A.We study the time-varying efficiency of nineteen members of the Federation of Euro-Asian Stock Exchanges (FEAS - an international organization comprising the main stock exchanges in Eastern Europe, the Middle East and Central Asia) by generalized Hurst exponent analysis of daily data with a rolling window technique. The study covers the six years of time period between January 2007 and December 2012. The results reveal that all FEAS members exhibit different degrees of long range dependence varying over time. We present an efficiency ranking of these members that provides guidance for investors and portfolio managers. Results show that the least inefficient market is Turkey followed by Romania while the most inefficient markets are Iran, Mongolia, Serbia and Macedonia. Throughout the considered time period, Turkey's stable Hurst exponent around 0.5 differs from others and shows characteristics of a developed financial market. For the federation members, strong positive relationship between efficiency and market liquidity is revealed. In the light of this fact, alternatives are suggested to improve market efficiency.Item Open Access Total factor productivity and macroeconomic instability(Routledge, 2011) Berument, Hakan; Dincer, N. N.; Mustafaoglu, Z.Total factor productivity (TFP) is an important component of growth for most countries. This article assesses the role of macroeconomic instability on TFP growth. We consider volatility in inflation, openness of an economy and financial market deepness as measures of macroeconomic instability. Empirical evidence provided from Turkey suggests that volatility of openness and financial market deepness reduce TFP growth, whereas volatility of inflation increases TFP growth. © 2011 Taylor & Francis.
