The realized volatility of financial returns is characterized by persistence and occurrence of unpredictable large increments. To capture those features, we introduce the Multiplicative Error Model with jumps (MEM-J). When a jump component is included in the multiplicative specification, the...

This paper studies the economic integration of East Asian economies among one another and with the US using co-movement of stock market prices. Both time-varying correlations and regressions are employed. We have traced the increased integration from 1980 to 2011 among the NIEs of Korea, Hong...

This paper employs a conditional quantile regression approach to quantify the dynamics of depression among adolescents, and examine the extent of true state dependence in youth depression conditional on unobserved individual heterogeneity and family socio5economic status. We use data on the...

Inflation expectations have recently received increased interest because of the uncertainty created by the Federal Reserve’s unprecedented reaction to the Great Recession. The effect of this reaction on the real economy is also an important topic. In this paper I use various surveys to produce...

We propose an automatic model order selection procedure for k-factor GARMA processes. The procedure is based on sequential tests of the maximum of the periodogram and semiparametric estimators of the model parameters. As a byproduct, we introduce a generalized version of Walker's large sample...

This paper investigates the implications of time-varying betas in factor models for stock returns. It is shown that a single-factor model (SFMT) with autoregressive betas and homoscedastic errors (SFMT-AR) is capable of reproducing the most important stylized facts of stock returns. An empirical...

The question whether alcohol in general, and different types of alcoholic beverages in particular (e.g., beer) are normal or inferior goods is a heavily disputed issue within economics and health research. Based on recently developed theories of preference adjustment this paper argues that the...

In this paper, we investigate the main features of the Italian financial cycle, extracted by means of a structural trend-cycle decomposition of the credit-to-GDP ratio, using annual observations from 1861 to 2011. In order to draw conclusions based on solid historical data, we provide a thorough...

Bu çalışmada 23.10.1987-15.02.2011 döneminde İMKB-100 endeksi getirisinin kaotik yapıya sahip olup olmadığının belirlenmesi ve kaotik davranış biçiminin varlığı durumunda öngörüde en başarılı sonucu verecek olan modelin seçilmesi amaçlanmıştır. Buna yönelik olarak ilk...
