Internet firms charge a wide range of prices for nearly homogeneous products and price dispersion vary significantly across markets. This study is an attempt to explain different levels of price dispersion across online product markets. We found price dispersion vary systematically with the number of firms offering the product and the markets at which consumers are more informed have smaller price dispersion. Moreover prices charged by individual retailers decline as the number of retailers selling the same product rise.


Exchange rate pass through into the export and import prices of Turkey
Abalı, Elif Ege; Akbostancı Özkazanç, Elif; Department of Economics (2004)
In this study, exchange rate pass-through into the export prices and import prices is analyzed separately at the disaggregate level. The study also attempts to differentiate exchange rate pass-through in the short-run and long-run. To analyze pass-through in the short-run, dynamic modeling is used. To analyze pass-through in the long-run, cointegration analysis is conducted. Estimation results show that exchange rate pass-through into the import prices is complete even at the disaggregate level. However, th...
Optimization of Supply Chain Systems with Price Elasticity of Demand
Kaplan, Ugur; TÜRKAY, METİN; Karasözen, Bülent; Biegler, Lorenz T. (2011-09-01)
A centralized multiechelon, multiproduct supply chain network is presented in a multiperiod setting with products that show varying demand against price. An important consideration in such complex supply chains is to maintain system performance at high levels for varying demands that may be sensitive to product price. To examine the price-centric behavior of the customers, the concept of price elasticity of demand is addressed. The proposed approach includes many realistic features of typical supply chain s...
Probabilistic day-ahead system marginal price forecasting with ANN for the Turkish electricity market
OZGUNER, Erdem; TOR, Osman Bulent; Güven, Ali Nezih (2017-01-01)
This study presents a system day-ahead hourly market clearing price forecasting tool for the day-ahead (DA) market and a system DA hourly marginal price forecasting tool for the real-time market of the Turkish electric market (TEM). These forecasting tools are developed based on artificial neural networks (ANNs). A series of historical price data of the TEM are utilized to model and optimize the ANN structure and to develop the ANN-based price forecasting tool. The methodology used to select the optimum ANN...
Volatility Spillover from Oil to Food and Agricultural Raw Material Markets
Kaltalıoğlu, Müge; Soytaş, Uğur (2011-05-01)
The upward movement in oil and food prices in the 2000s has attracted interest in the information transmission mechanism between the two markets. This paper investigates the volatility spillover between oil, food consumption item, and agricultural raw material price indexes for the period January 1980 to April 2008.The results of the Cheung-Ng procedure show that variation in oil prices does not Granger cause the variance in food and agricultural raw material prices. Since there is no volatility spillover f...
Volatility spillover from world oil spot markets to aggregate and electricity stock index returns in Turkey
Soytaş, Uğur; Oran, Adil (2011-01-01)
This study examines the inter-temporal links between world oil prices, ISE 100 and ISE electricity index returns unadjusted and adjusted for market effects. The traditional approaches could not detect a causal relationship running from oil returns to any of the stock returns. However, when we examine the causality using Cheung-Ng approach we discover that world oil prices Granger cause electricity index and adjusted electricity index returns in variance, but not the aggregate market index returns. Hence, ou...
