Education-occupation mismatch in Turkish labor market

There is a consensus that one of the most important ingredients for high and sustainable growth is human capital accumulation. Yet, a dierent strand of literature argues that there are some frictions in the labor markets of most countries that result in possible education-occupation mismatches, and consequently inefficiencies. Despite a significant amount of research using data from advanced economies there are very few studies on developing economies. Considering that human capital is scarce in these countries, whether it is efficiently allocated is arguably relatively more important. This paper using data from two different years examines the incidence of overeducation in Turkey. The ndings show that there is a signicant amount of over- and undereducated workers, and they are paid signicantly less than those with the same level of education but working in jobs that require education levels that match their own. The magnitude of the incidence and the impact of mismatches on wages are, however, not too different than in most developed economies

Schur functions and their realizations in the slice hyperholomorphic setting

we start the study of Schur analysis in the quaternionic setting using the theory of slice hyperholomorphic functions. The novelty of our approach is that slice hyperholomorphic functions allows to write realizations in terms of a suitable resolvent, the so called S-resolvent operator and to extend several results that hold in the complex case to the quaternionic case. We discuss reproducing kernels, positive definite functions in this setting and we show how they can be obtained in our setting using the extension operator and the slice regular product. We define Schur multipliers, and find their co-isometric realization in terms of the associated de Branges-Rovnyak space

Backward recalculation of seasonal series affected by economic crisis: a Model-Based-Link method for the case of Turkish GDP

When attempting to deal with the recalculation process, it is hard to answer the question “Does the recalculated series include economic events and seasonal behaviours in the past?”. This paper discusses some alternative backward recalculation methods and presents the applications and their results relative to the Turkish Gross Domestic Product (GDP) series. Using comparative analysis, it is shown that ordinary ARIMA forecasts and signal extraction methods are not successful at taking into account past events in the backward recalculated series. A new innovative method, named Modelbased-link, is then proposed and suggested by the authors in order to be able to take past economic events and seasonal patterns into account when the series is to be backward recalculated. A first application of this new method is run on the quarterly series of the Turkish GDP. In addition, it is shown that the Model-based-link method can be extended to data sets of different frequencies (i.e. annual data). Consequently, it can be claimed that a comparable recalculated quarterly and annual Turkish GDP series for forthcoming data is obtained. The paper is structured as following: section 1 introduces the reader to the state of the art in the current literature; section 2 defines the information set to be backward recalculated and presents some statistics on the data while section 3 presents the main methodological statistical aspects of classical methods compared to the methodological scheme of the Model-based-link that can be used for the recalculation process. Section 4 presents results of the methods mentioned in the previous section and section 5 discusses the extension of the Model-based-link method to monthly data and includes an application for annual data; section 6 concludes. Finally, section 7 presents topics for discussion and challenges for continuation of the analysis

Exchange rates and employment in Turkish manufacturing

This paper investigates the effects of exchange rate fluctuations on Turkish manufacturing employment and wages using data for a panel of manufacturing industries over the period 1981-1999. The net effect of depreciations are found to be negative for both employment and wages, though the effects on wages are more pronounced. The negative effect of high dependency of Turkish manufacturing industries on foreign inputs overcomes the positive effect of depreciations on competitiveness.exchange rates, labor market, manufacturing, Turkey

Topological convolution algebras

In this paper we introduce a new family of topological convolution algebras of the form $\bigcup_{p\in\mathbb N} L_2(S,\mu_p)$, where $S$ is a Borel semi-group in a locally compact group $G$, which carries an inequality of the type $\|f*g\|_p\le A_{p,q}\|f\|_q\|g\|_p$ for $p > q+d$ where $d$ pre-assigned, and $A_{p,q}$ is a constant. We give a sufficient condition on the measures $\mu_p$ for such an inequality to hold. We study the functional calculus and the spectrum of the elements of these algebras, and present two examples, one in the setting of non commutative stochastic distributions, and the other related to Dirichlet series.Comment: Corrected version, to appear in Journal of Functional Analysi

On the reproducing kernel Hilbert spaces associated with the fractional and bi-fractional Brownian motions

We present decompositions of various positive kernels as integrals or sums of positive kernels. Within this framework we study the reproducing kernel Hilbert spaces associated with the fractional and bi-fractional Brownian motions. As a tool, we define a new function of two complex variables, which is a natural generalization of the classical Gamma function for the setting we conside

Point evaluation and Hardy space on a homogeneous tree

We consider transfer functions of time--invariant systems as defined by Basseville, Benveniste, Nikoukhah and Willsky when the discrete time is replaced by the nodes of an homogeneous tree. The complex numbers are now replaced by a C*-algebra built from the structure of the tree. We define a point evaluation with values in this C*-algebra and a corresponding ``Hardy space'' in which a Cauchy's formula holds. This point evaluation is used to define in this context the counterpart of classical notions such as Blaschke factors. There are deep analogies with the non stationary setting as developed by the first author, Dewilde and Dym.Comment: Added references, changed notation
