The problem of instrument proliferation and its consequences (overfitting of the endogenous explanatory variables, biased IV and GMM estimators, weakening of the power of the overidentification tests) are well known. This paper introduces a statistical method to reduce the instrument count. The...

A common problem in credit risk management is the estimation of probabilities of rare default events in high investment grades, when sufficient default data are not available. In addressing this issue, increasing attention has been paid to the use of continuous time Markov chains for modeling...

In the last decades the phenomenon of wine tourism has shown a remarkable growth in several countries and continents of the world, from Australia through the United States to Europe, encouraging the interest of many scholars and producing a large volume of studies. According to the current...

Bu çalışmada, Türkiye’de hanehalkı zaruri harcamaları (gıda ve alkolsüz içecekler, sağlık ve eğitim) ile hanehalkı kullanılabilir geliri, hanehalkı büyüklüğü (hanede yaşayan bireylerin sayısı), hanehalkı tipi, ikamet edilen konutun mülkiyet tipi ve hanehalkının...

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 a természeti erőforrások és környezeti javak változásainak pénzbeli értékelésére lehetőséget adó módszereket, illetve azok elméleti hátterét kívánja áttekinteni. Ahhoz, hogy a nehezen számszerűsíthető, de annál jelentősebb hatások ne maradjanak ki az...

A szerző 19 OECDország lakossági villamosenergiafelhasználásának keresztmetszeti elemzésével olyan módszert dolgozott ki, amely alkalmas arra, hogy szétválassza a rejtett gazdaságtól független és az azzal kapcsolatos lakossági villamosenergiafogyasztást. A módszer lehetővé...

In 1998 Italy introduced a restricted version of an Allowance for Corporate Equity, called Dual Income Tax. Using data integrating Italy’s Institute for Statistics enterprise survey data and company accounts, we explore the effects of the Dual Income Tax on enterprise performance in 1998-2001....
