In this study, we conducted a research as to whether splits in shares on the ISE-ON Index at the Istanbul Stock Exchange have had an impact on returns generated from shares between 2005 and 2011 or not using event study method. This study is based on parametric tests, as well as on nonparametric...

We study a general class of semiparametric estimators when the innite-dimensional nuisance parameters include a conditional expectation function that has been estimated nonparametri- cally using generated covariates. Such estimators are used frequently to e.g. estimate nonlinear models with...

Decision making can be a complex process requiring the integration of several attributes of choice options. Understanding the neural processes underlying (uncertain) investment decisions is an important topic in neuroeconomics. We analyzed functional magnetic resonance imaging (fMRI) data from...

This paper studies nonlinear cointegration models in which the structural coefficients may evolve smoothly over time. These time-varying coefficient functions are well-suited to many practical applications and can be estimated conveniently by nonparametric kernel methods. It is shown that the...

This paper studies a general class of nonlinear varying coefficient time series models with possible nonstationarity in both the regressors and the varying coffiecient components. The model accommodates a cointegrating structure and allows for endogeneity with contemporaneous correlation among...

We study estimation and non-parametric identification of preferences in two-sided matching markets using data from a single market with many agents. We consider a model in which preferences of each side of the market are vertical, utility is non-transferable and the observed matches are pairwise...

A tanulmány szerzője egy új, nem paraméteres eljárás (OCRA) alkalmazási lehetőségeit mutatja be. A húsipar tartósnak tűnő hatékonysági és versenyképességi problémái különösen indokolttá teszik, hogy új eljárás segítségével a működési versenyképesség fogalmát...

A munkanélküli-járadékból Magyarországon a legtöbben nem úgy kerülnek ki, hogy állást találnak, hanem úgy, hogy kimerítik a járadékot. A cikk ezzel összefüggő két problémát vizsgál. 1. Milyen hatást gyakorol a járadék megszűnése az érintettek életkörülményeire?...

Tanulmányunk egyrészt arra a kérdésre keresi a választ, vajon helytálló-e a tőkepiaci árazási modell (CAPM) azon feltevése, hogy a piaci kockázat mérőszáma, a béta és a várható hozam között lineáris kapcsolat áll fenn. Másrészt nem tudjuk, hogy megalapozott-e a...
