Developments in shale oil production technologies made the US, already the most important oil consumer, an important oil producer and exporter. This paper examines the response of shale oil production across eight production basins in the US to both US domestic and foreign oil demand shocks. The empirical evidence reveals that shale oil production...

This study analyzes the asymmetric effects of the price shocks of two global crude oil benchmarks (Dated Brent and Dubai) on three Russian crude oil prices: Urals, ESPO, and Sokol. The empirical evidence suggests that an increase in benchmark oil prices causes a rise in the selling prices of these Russian crude oil grades, and a drop in benchmarks...

Article
This paper studies the effects of various economic and psychological factors on the switching behavior of large-scale electricity consumers in Turkey. Switching frequency and switching direction are two variables used to analyze switching behavior. The former is concerned with how often retailers change their suppliers. On the other hand, switching...
Article
This paper studies the effects of the exchange rate regime of the Mexican economy on how the oil price shocks affect the domestic economic performance by considering the period from January 1992 to December 2019. The empirical evidence reported here reveals that a positive oil price shock appreciates the local currency, increases interest rates, ou...
Article
This study aims to assess and quantify the effects of potential economic drivers on the Brent-Dubai price spread using the time-dependent Kalman filtering technique. To understand the pricing mechanism of crude oils, it is necessary to distinguish the driving forces of the world oil market. The Brent-Dubai price spread is selected as a global indic...
Chapter
Starting from the liberalization of the electricity market in Turkey, the annual switching rates have remained at low levels for both residential and industrial consumers. This study aims to investigate the supplier switching behavior of large scale industrial consumers in the Turkish Electricity market with an emphasis on behavioral factors. The d...
Article
Purpose The purpose of this paper is to use the novel data from the primary vision to determine the main financial and economic drivers of this revolutionary shale oil production and how these drivers changed after 2016 when the US removed its oil-exporting ban. Design/methodology/approach In this paper, the authors use the vector autoregressive m...
Article
Measuring the size of the informal diesel market is important for determining tax revenue losses and identifying inefficiencies in tax policies. The conventional ways of assessing the informal sector entail either not allowing the measurement of the size of the informal sector across time or assuming a stable relationship between diesel consumption...
Article
In this study, we provide empirical evidence to emphasize the crucial role of cross-border electricity trade for decreasing the use of fossil fuels in power industries and attaining higher electricity supply from solar and wind energy sources. We collected data for 48 countries across three continents (Americas, Europe and Asia) from 1991 to 2018 t...
Article
Many studies have examined the asymmetric effect of US dollar-denominated crude oil prices on petroleum product prices. The ‘rockets and feathers’ argument suggests that a crude price increase raises petroleum product prices more than a corresponding decrease in crude prices lowers product prices. However, for the countries that do not use the US d...
Article
The Fisher Effect is one of the most widely studied relationships in monetary economics. Previous studies have found little evidence of a Fisher effect in pre-World War I data for the United Kingdom. An explanation for this is the near white noise property of the inflation rate under the Classical Gold Standard. There is more evidence of a Fisher e...

The effects of increasing versus decreasing interest rates on economic performance are different. The members of the central bank's monetary policy committee are criticized heavily by the government when the interest rates are increased and praised when they are decreased in Turkey. Empirical evidence from Turkey suggests that the central bank is m...
Article
Full-text available
It is a well-established regularity that permanent oil price shocks do not have a permanent effect on the current account deficit. This requires that sub-components of the current account or trade balance will make the necessary adjustments to accommodate the higher energy bill of a country triggered by permanent crude oil price increases. Empirica...
Article
The duration of Global Financial Cycles (GFCs) have a role in the global financial environment which is shaped by the fluctuations in short-term capital flows, changes in monetary conditions in the center economies and co-movement in asset prices. The duration of GFCs for a set of global financial data – the VIX index, the TED spread and the 3-Mont...
Article
Since the 2008 global financial crisis, central banks have been using a new set of policy tools in addition to conventional tools (such as short‐term interest rates) to conduct monetary policy. This paper employs a methodology that captures 25 of these tools with a limited number of factors for Turkey. Due to a set of factors such as the high volat...
Article

The day of the week effect is one of the regularities observed in financial markets which suggests that Friday returns are higher than Monday returns. One of the possible reasons for this regularity is that the date of trade in equity markets is not always the same as the date that payment is made, or the settlement date. The number of days that in...

This article contributes to the asset pricing literature by offering an alternative missing factor: the excess holdings of foreign investors. To incorporate this factor, we mimic the portfolio of foreign investors in Borsa Istanbul (BIST) with respect to portfolio preferences (foreign ownership) using the Fama and French’s three-factor model. Our f...

Along with most other central banks, Turkey’s central bank has implemented unconventional policies since the 2007/2008 financial crisis. Financial stability has been one of the targets of these macroprudential policies. However, since Turkey is working toward this goal without increasing its inflation rate, tracking only short-term interest rates t...

One advantage cited for formal inflation targeting is that by anchoring inflationary expectations this policy framework would aid in the pricing of long-term securities. Long-term interest rates would become less sensitive to temporary shocks to the economy including policy-induced changes in short-term interest rates. This paper examines the exper...
Article
A coherent method to measure the effectiveness of a monetary policy improves the monetary authority’s management capacity and renders the possibility of applying sound policies prior to and during a crisis.

There is an emerging but important literature on the effects of sport events such as soccer on stock market returns. After a soccer team's win, agents discount future events more favorably and increase risk tolerance. Similarly, after a loss, risk tolerance decreases. This paper directly assesses risk tolerance after a sports event by using daily d...
Article
We hypothesize that results of football (soccer) teams affect the risk perception of people. People choose riskier investments after a win and less risky investments after a loss; this leads to higher (lower) returns in the stock market. These hypotheses are tested for the international matches of Turkey's three most popular teams (Beşiktaş, Fenerb...
