    Determinants of Investment in the Manufacturing Sector in Turkey
    (Kadir Has Üniversitesi, 2017) Doruk, Ömer Tuğsal; Orhangazi, Özgür
    This dissertation focuses on the determinants of investment in Turkish manufacturing sector. it gives a detailed framework and complementary analysis of the determinants of investment in Turkish manufacturing sector. First i examine the financing constraints hypothesis for the manufacturing sector. The financing constraints have a controversial place in the current literature and for Turkey there has been a limited literature in this field even-though the relation between financing constraints and investment has traditionally had a special place in investment studies. Second i analyze the relation between cash holding or staying liquidity and investment as well as the effect of cash holdings on investment. Third i examine the effect of profitability on investment for Turkish manufacturing sector. Fourth i review the effect of free cash flow on investment. i use free cash flows to examine the relationship between underinvestment and financing constraints. i also investigate the effect of different institutional aspects of investment such as holding structures and TUSiAD membership. This dissertation offers a detailed contribution to the understanding of investment behavior of publicly held firms in the manufacturing sector in Turkey. Moreover this dissertation gives a comprehensive framework for measuring financing constraints for investment decisions. Finally this dissertation makes a significant contribution to linking the conditions of financing constraints and underinvestment.

    Evaluation of Reform in Turkish Electricity Sector :a Cge Analysis
    (Kadir Has Üniversitesi, 2016) Dautaj Şenerdem, Erısa; Akkemik, K. Ali
    Turkey's electricity market has undergone extensive reform since 2001 through market liberalization unbundling privatization and establishment of organized power markets retail market opening and the establishment of an independent energy regulatory authority. i employ a static computable general equilibrium (CGE) model to test the impact of power sector reform on the economy. Major findings suggest reform has been beneficial to the economy. Market liberalization has a positive impact on gross domestic product when implemented on all state-run companies simultaneously. Stronger participation of state-run companies in the day-ahead market generates a positive effect on the economy similar to that of larger private participation in the sector with the GDP turning around 0.2-0.3% above its base levels after each shock. Stronger demand-side participation also affects the economy positively. A simulation of all reform elements combined generates a deviation of GDP by 0.2% above its baseline.

    Explaining the Labor Share of Income :a Synthetic Analysis With Capital Account Openness and Financial Development Oecd and Non-Oecd Countries 1995-2015
    (Kadir Has Üniversitesi, 2017) Özdemir, Onur; Ertan, Sabri Arhan
    The negative influences of economic downturn which started with the 2007-2008 crisis still maintain to affect the global economy as of 2017. in this framework current mainstream economic policies are being re-examined and need to be renewed. Especially with the Keynesian paradigm coming to the point of collapse at socio-economic scale since 1970s the exacerbating anti-labor movements have obtained the power to enforce the fundamental policy proposals all over the world. Among many different kinds of approaches neo-liberal policy unity and thereby the neoclassical paradigm were the ones that had taken the power. However this transformation within the system was not being easy due to the changes in the interests of the socio-economic and political base of the interests of policymakers and of agents. in other words on a class-based the neoliberal period in which the labor-capital conflict has reached its most serious level in history required of the organization of many parameters especially by pressure in favor of capital. in its essence neoliberalism can be also regarded as a social economic and political counter-attack against the labor-based gains obtained in the Keynesian period within the labor-capital accord. At the scientific level it is possible to obtain evidences or outcomes in many different spheres (e.g. the rate of unionization the level of unemployment rate flexible labor market policies and cheap labor-based production planning). However the most important example of this case in the macroeconomic framework can be understood in falling labor share ratios. As will be noted in the study this decline is valid both for developed and developing country groups.

    The Impact of Borrowing on Household Saving Behavior the Case of Turkey 2003 – 2012
    (Kadir Has Üniversitesi, 2018) Şenol, Serdar; Orhangazi, Özgür
    The aim of this Ph.D. thesis is to contribute to the vast literature on the determinants of household saving and reassess the precautionary saving preferences of Turkish households by introducing liquidity and debt related factors aside from the general saving contributors. The precautionary saving motive against future income uncertainties defined as one of the leading indicators of saving preferences is effected through liquidity effects especially in less financialized economies with uneven income distributions. The sharp decline in Turkish households‘ saving ratio in the global financialization period is a good example of the changing saving dynamics with liquidity and debt concepts. in my thesis i use the Turkish Household Budget Surveys for the period of 2003 to 2012. in addition to the socioeconomic and demographic information in these surveys i also utilize generated liquidity and debt indicators. Descriptive analysis confirms the predictions of the saving literature showing young and impatient households to be less inclined to save. Education level improves while employment focuses on the service sector. Uneven income distribution is one of the major factors to limit saving and also precautionary saving opportunities for a significant portion of observations and elevates the importance of liquidity conditions. Empirical analysis confirms the presence of precautionary saving in Turkish households while its significance is lower after the 2008 crisis once liquidity effects are introduced. Moreover wealthy and entrepreneur households are observed to be natural savers. Presumably liquidity constrained households do not demonstrate a difference in precautionary saving preferences but confirming the predictions of the liquidity constraint households hypothesis they dissave with easier liquidity conditions. The presence of debt is an additional saving motive. it is suggested that an improvement in income distribution and a decline in the liquidity constrained households‘ share would rebalance the low saving level of Turkish households.

    Input Substitutability, Energy Intensity and Efficiency in Us Agriculture
    (Kadir Has Üniversitesi, 2014) Gazel, Tuğçe Uygurtürk; Zaim, Osman
    Yenilenemeyen kaynakların, özellikle enerjinin, üretim aşamasında önemli ölçüde belirleyici etkisi bulunmaktadır. 1970 lerden itibaren yaşanan petrol krizleri,sınırlı enerji kaynaklarının kullanımı konusundaki bilinci daha da pekiştirmiş, bu alandaki performans ölçüm yöntemleri yoğun bir şekilde çalışılmaya başlanmıştır. Bu tezde Amerikan tarım sektorünün 1960-2004 yılları arasındaki panel veri seti kullanlarak üç önemli soruya yanıt aranmıştır. İlk olarak, girdilerin birbirlerinin yerine ne ölçüde ikame edilebileceği sorusu esnek fonksiyonel formların yardımıyla çalışılmış daha sonra enerji yoğunlugu ve enerji üretkenliği kavramları literatürde var olan ölçüm tekniklerinin kabul edilen eksikliklerini gidermek amacıyla yeni geliştirilen ölçüm tekniğiyle hesaplanmıştır. Son olarak da tarım sektörünün etkinliği parametrik, yarı parametrik ve parametrik olmayan teknikler kullanılarak hesaplanmıştır. Elde edilen bulgular, Amerikan tarımında girdi ikamesi bağlamında kapsamlı bir veri çerçevesi sunarken, yeni yöntemle elde edilen performans belirleyicileri (enerji yoğunlugu, enerji verimliliği) var olan yöntemlerle elde edilen bulgulara göre bariz farklar ortaya koymaktadır.
