Dynamics of the trade balance: The Turkish J-curve

The J-curve hypothesis suggests a specific pattern for the response of trade balance to real exchange rate changes: a real depreciation initially worsens the trade balance, but through time the trade balance improves, and thus the response of the trade balance over time generates a tilted J shape. This study investigates the existence of a J-curve in the Turkish data in the period of 1987-2000, by using quarterly data. First an error correction model is estimated to differentiate between the long-run equilibrium and short-run dynamics. Then the response of trade balance to real exchange rate shocks are investigated by using the generalized impulse response methodology. Even though the suggested long-run pattern, which is the improvement of the trade balance in response to a real depreciation emerges, our results do not exactly support the J-curve hypothesis in the short-run. In this study we found that the short-run behavior of the trade balance in response to real exchange rate shocks show an S-pattern reminiscent of the Backus et al (1994) rather than the J-curve pattern.J-Curve, trade balance, Marshall-Lerner condition, cointegration, impulse response analysis

Turkish Twin Effects: An Error Correction Model of Trade Balance

Twin deficit hypothesis mainly states that government budget deficits will cause trade deficits. However, this is not the only theoretically possible relationship between the budget deficit and the trade deficit. On the other extreme if Ricardian equivalence hypothesis holds it is also possible that two deficits are not related at all. In this study these hypotheses between the budget deficit and trade deficit for Turkey between 1987 - 2001 period are examined by using the cointegration methodology and by estimating an error correction model. This enabled us to search the relationship between the internal and external deficits both in the short-run and in the long-run. Our analysis showed that there is a long-run relationship between the two deficits. Also the short-run model yielded that worsening of the budget balance worsens the trade balance. Therefore we have concluded that the twin deficit hypothesis holds, and Ricardian equivalence hypothesis is not valid for Turkey during the study period.Twin deficits, trade deficit, budget deficit, Ricardian equivalence, cointegration, error correction models, unit roots, Turkey

Pollution Haven Hypothesis and the Role of Dirty Industries in Turkey’s Exports

Pollution haven hypothesis argues that the industries that are highly pollution intensive i.e. dirty industries, have been migrating from developed economies to the developing world. It is argued that the environmental concerns of the developed economies caused them to enact strict environmental regulations, which have increased the cost of production of the dirty industries at home. On the other hand, the developing countries with their low wages and lax environmental regulations have been attractive alternative producers in these sectors. At the same time this migration is also beneficial for developing countries that are in need of financial resources for industrial development. Consequently, developing countries provide pollution havens for dirty industries. In this process while the dirty industries have been migrating to the developing countries, the developed countries also have become net importers of these sectors. In this study the pollution haven argument for Turkey, for 1994-1997 period is examined. The study focuses on the pollution haven hypothesis from trade perspective by looking at the manufacturing industry data at 4-digit ISIC detail by using the panel data approach. It is found that exports increase as the dirtiness of the industries increases, providing some evidence for the pollution haven hypothesis.Turkey, Pollution Haven Hypothesis, environment, manufacturing

CO2 Emissions vs. CO2 Responsibility: An Input-Output Approach for the Turkish Economy

Recently, global warming (greenhouse effect) and its effects have become one of the hottest topics in the world agenda. There have been several international attempts to reduce the negative effects of global warming. Kyoto Protocol can be cited as the most important agreement which tries to limit the countries’ emissions within a time horizon. For this reason it becomes important to calculate the greenhouse gas emissions of countries. The aim of this study is to estimate the amount of CO2 -the most important greenhouse gas- emissions, for the Turkish economy. An extended input-output model is estimated by using 1996 data in order to identify the sources of CO2 emissions and to discuss the share of sectors in total emission. Besides ‘CO2 responsibility’, which takes into account the CO2 content of imports, is estimated for the Turkish economy. The sectoral CO2 emissions and CO2 responsibilities are compared and these two notions are linked to foreign trade volume. One of the main conclusions is that the manufacturing industry has the first place in both of the rankings for CO2 emissions and CO2 responsibilities; while agriculture and husbandry has the last place.CO2 responsibility, Turkey, input-output analysis

Environmental Impact of Customs Union Agreement with EU on Turkey’s Trade in Manufacturing Industry

In this study, we analyze Turkey’s manufacturing industry trade by estimating sectoral import and export demand equations for 1980-2000. The study aims to understand whether the trade in the manufacturing industry complies with pollution haven hypothesis, and whether the free trade environment provided by the customs union (CU) agreement altered the trade pattern of the clean and dirty industries. Results of our econometric models have shown that while CU positively affects the import demand, it does not have any significant impact on the export demand of Turkish manufacturing industry. In terms of the environmental impact, distinction between clean and dirty industries turns out to be significant for both import and export demand. In general, our findings suggest that both clean and dirty industries’ import demand increase during the study period. In terms of export demand, clean industries’ export demand declines whereas dirty industries’ export demand increases compared to the total demand.Environmental impact analysis, EU, Turkey, manufacturing industry

A decomposition analysis of CO2 emissions from energy use: Turkish case

Environmental problems, especially "climate change" due to significant increase in anthropogenic greenhouse gases, have been on the agenda since 1980s. Among the greenhouse gases, carbon dioxide (CO2) is the most important one and is responsible for more than 60% of the greenhouse effect. The objective of this study is to identify the factors that contribute to changes in CO2 emissions for the Turkish economy by utilizing Log Mean Divisia Index (LMDI) method developed by Ang (2005) [Ang, B.W., 2005. The LMDI approach to decomposition analysis: a practical guide. Energy Policy 33, 867-871]. Turkish economy is divided into three aggregated sectors, namely agriculture, industry and services, and energy sources used by these sectors are aggregated into four groups: solid fuels, petroleum, natural gas and electricity. This study covers the period 1970-2006, which enables us to investigate the effects of different macroeconomic policies on carbon dioxide emissions through changes in shares of industries and use of different energy sources. Our analysis shows that the main component that determines the changes in CO2 emissions of the Turkish economy is the economic activity. Even though important changes in the structure of the economy during 1970-2006 period are observed, structure effect is not a significant factor in changes in CO2 emissions, however intensity effect is.Decomposition analysis CO2 emissions Turkey

CO2 emissions of Turkish manufacturing industry: A decomposition analysis

In this study, CO2 emissions of Turkish manufacturing industry are calculated by using the fuel consumption data at ISIC revision 2, four digit level. Study covers 57 industries, for the 1995-2001 period. Log Mean Divisia Index (LMDI) method is used to decompose the changes in the CO2 emissions of manufacturing industry into five components; changes in activity, activity structure, sectoral energy intensity, sectoral energy mix and emission factors. Mainly, it is found that changes in total industrial activity and energy intensity are the primary factors determining the changes in CO2 emissions during the study period. It is also indicated that among the fuels used, coal is the main determining factor and among the sectors, 3710 (iron and steel basic industries) is the dirtiest sector dominating the industrial CO2 emissions in the Turkish manufacturing industry.Decomposition analysis CO2 emissions Turkey Manufacturing industry
