Labor market vision has changed from a stock perspective to a flow perspective in the recent years. Majority of labor markets in many high income countries are specified by these gross flows. Due to these large flows, a major issue arises in matching workers and jobs in labour market which results in coexistence of high number of unfilled vacancies and unemployed people. Different approaches are applicable in the literature to match the right candidate with the right job post. Yet, as far as we know a sophisticated statistical analysis or a procedure for employing a Job Matching Scheme (JMS) for Turkish Employment Agency (TEA) does not exist. The main aim of this thesis study is to develop a statistical approach for designing a JMS by proposing a new Classification Algorithm for Categorical Data with Incremental Feature Selection (CACDIFES) and a Matching Algorithm which consists of a combination of scoring and sorting algorithms by using Independently Weighted Overlap Metric (IWOM). Apart from the studies in the literature, this thesis proposes a new Incremental Feature Selection (IFS) algorithm, an Independently Weighted Value Difference Metric (IWVDM) and a modified version of Overlap Metric (OM) which can be applied to any type of categorical data sets. Algorithms proposed in this thesis are applied to TEA data set and data sets obtained from UCI Machine Learning Repository. Experimental results reveal that our proposed metric is superior to previously introduced ones, and our JMS is able to match all vacant jobs with suitable job seekers.

Labor market institutions and industrial performance: an evolutionary study Kilicaslan, Yilmaz; Taymaz, Erol (2008-08-01) This study investigates the impact of labor market institutions on industrial performance from a Schumpeterian perspective. We suggest that labor market institutions play a very important role in the process of creative destruction, because they may create an environment that encourages and enforces innovation, and help to reallocate resources, most importantly labor, through swift elimination of weak performers. We specifically look at the effects of the quantity of labor market regulations and inter-indus...
A NEW ROBUST OPTIMIZATION TOOL APPLIED ON FINANCIAL DATA Ozmen, A.; Weber, Gerhard Wilhelm; Karimov, A. (2013-07-01) Recent financial crises, with an increased volatility and, hence, uncertainty factors, have introduced a high "noise" into the data taken from the financial sectors and overall from any data related to the financial markets, so that the known statistical models do not give trustworthy results. As we know the solutions of the optimization problem can show a remarkable sensitivity to perturbations, coming from the data, in the parameters of the problem. To overcome this kind of difficulties, the model identif...
Analyzing Housing Market Dynamics using Linear and non-Parametric Models Yılmaz, Bilgi; Yerlikaya Özkurt, Fatma; Kestel, Sevtap Ayşe (2018-10-07) This paper analyzes the dynamic effect of macroeconomic indicators, such as financial and commodity market indicators on national housing markets. Furthermore, it does not only focus on the impact of the variables but also introduces a variety of models that based on the generalized linear models and multivariate adaptive regression splines. The models help us to identify the macroeconomic drivers of housing markets. Since the US has an adequate housing market data, the empirical analysis within the paper f...
A Novel Interactive Fuzzy Programming Approach for Optimization of Allied Closed-Loop Supply Chains Calik, Ahmet; YAPICI PEHLİVAN, NİMET; PAKSOY, TURAN; Weber, Gerhard Wilhelm (2018-01-01) In recent years, the relationship between companies and suppliers has changed with the continuous rise in environmental awareness and customer expectations. In order to fulfill customers' needs, the actors in a Supply Chain (SC) network sometimes compete and sometimes cooperate with each other. In SC management, both competitive and collaborative strategies have become important and have required different points of view. In a collaborative environment, companies should strive for common targets with mutual...
Application of r-vine copula method in Istanbul stock market data: A case study for the construction sector Farnoudkia, Hajar; Purutçuoğlu Gazi, Vilda (Ankara Yıldırım Beyazıt Üniversitesi , 2020-12-01) In the stock market, the relationship between the sectorial changes can be very informative in order to predict the changes in prices of assets from each sector. In order to understand these sectorial relations, various studies have been conducted. In one of the recent studies, the construction sector in Turkey was investigated in terms of its effect in other Turkish sectors since it is one of the leading sectors in Turkey and its assets have a significant impact in stock markets. Hereby, in this study we d...
