Item Open Access Bertrand-edgeworth equilibrium in a cash-in-advance economy(Oxford University Press, 2003) Başçı, E.; Saglam, I.This paper is about price and wage competition in a dynamic general equilibrium model. We consider an equity financed economy where firms need money to finance their input costs. Part of the output is sold for money to be used in the next period as working capital and the remaining part is distributed to owners as real dividends. We first characterize the steady state competitive equilibrium path. Second, we study whether this competitive equilibrium can be supported as a pure strategy Nash equilibrium in price and wage setting games. We prove a positive result for price competition and a negative one for wage competition.Item Open Access Bidding structure, market efficiency and persistence in a multi-time tariff setting(Elsevier, 2016) Avci-Surucu, E.; Aydogan, A. K.; Akgul, D.The purpose of this study is to examine the fractal dynamics of day ahead electricity prices by using parametric and semi parametric approaches for each time zone in a multi-time tariff setting in the framework of bidding strategies, market efficiency and persistence of exogenous shocks. We find that that electricity prices have long term correlation structure for the first and third time zones indicating that market participants bid hyperbolically and not at their marginal costs, market is not weak form efficient at these hours and exogenous shocks to change the mean level of prices will have permanent effect and be effective. On the other hand, for the second time zone we find that price series does not exhibit long term memory. This finding suggests the weak form efficiency of the market in these hours and that market participants bid at their marginal costs. Furthermore this indicates that exogenous shocks will have temporary effect on electricity prices in these hours. These findings constitute an important foundation for policy makers and market participants to develop appropriate electricity price forecasting tools, market monitoring indexes and to conduct ex-ante impact assessment.Item Open Access The determinants of privatization prices: evidence from Turkey(Routledge, 2003) Arin, K. P.; Okten, C.This paper analyses the determinants of privatization prices in a multi-industry study using a sample of 68 recently privatized firms from Turkey. Results show that revenue and market characteristics are significant determinants of privatization prices while current cost and profit indicators are not. It is argued that potential buyers regard these state firms as inefficient, therefore do not take into consideration their current costs and profits in determining their value. When the dependent variable is altered by dividing the firm's privatization price by the firm's sales (revenues), it is found that sales-adjusted privatization prices are responsive to firms' profit margins. However, this result does not hold when the sample is restricted to a single industry. Profit margins along with other profitability and firm efficiency measures are no longer significant determinants of sales-adjusted privatization prices in the cement industry analysis. Unexploited production opportunities measured by capacity utilization ratios, and complete private ownership resume a more important role.Item Open Access Econometric tests of asset price bubbles: taking stock(Wiley-Blackwell Publishing Ltd., 2008) Gürkaynak, R. S.Can asset price bubbles be detected? This survey of econometric tests of asset price bubbles shows that, despite recent advances, econometric detection of asset price bubbles cannot be achieved with a satisfactory degree of certainty. For each paper that finds evidence of bubbles, there is another one that fits the data equally well without allowing for a bubble. We are still unable to distinguish bubbles from time-varying or regime-switching fundamentals, while many small sample econometrics problems of bubble tests remain unresolved. © 2008 The Author Journal compilation © 2008 Blackwell Publishing Ltd.Item Open Access Openness and the effectiveness of monetary policy: empirical evidence from Turkey(Routledge, 2003) Berument, Hakan; Doǧan, B.The empirical evidence suggests that openness decreases the effect of monetary policy on output, however the effect on prices is not statistically significant. In this study these predictions are tested over the open economy of Turkey for quarterly data from 1987:1 to 2001:1. This study assesses how the openness affects the effectiveness of monetary policy on output and prices.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 Testing Marshall-Lerner condition: a non-parametric approach(Routledge, 2004) Mahmud, S. F.; Ullah, A.; Yucel, E. M.In this study, non-parametric kernel estimation technique has been employed to estimate import and export price elasticities for six developed countries. Based on the estimates of these elasticities Marshall-Lerner condition has been examined. In general the condition is only partially satisfied in the sub-sample periods. The results also suggest that the condition is more likely to be satisfied under fixed exchange rate regime. © 2004 Taylor and Francis Ltd.Item Open Access Turkey's experience with disinflation: where did all the welfare gains go?(Routledge, 2013) Neyapti, B.This article measures the welfare gains from disinflation in Turkey during the 2000s. Estimated welfare gains exceed the real output gains, which is likely to arise from persisting allocative inefficiencies, pointing at the need for further structural and institutional reforms for the benefits of price stability to be utilized towards achieving sustainable development. © 2013 Copyright Taylor and Francis Group, LLC.
