We consider the problem of estimating the volatility of a financial asset from a time series record of length T. We believe the underlying volatility process is smooth, possibly stationary, and with potential abrupt changes due to market news. By drawing parallels between time series and...

In this note, we investigate a test for the existence of a middle "band of inaction" in a three-regime threshold vector error correction model (TVECM). For this purpose we propose a supremum Wald statistic, derive its limiting distribution and calculate its critical values through simulations.

In this paper a three-regime multivariate threshold vector error correction model (TVECM) with a "band of inaction" is formulated to examine the expectation hypothesis of the term structure (EHTS) of interest rates and uncovered interest rate parity (UIRP) for U.S. and Swiss rates. Tests for no...

The paper generalises estimation and inference procedures for a threshold VECM with more than one cointegrating relation. We derive estimators of long-run parameters and loading factors by means of a reduced rank regression. We provide their asymptotic distributions and propose a testing...

This paper proposes a simple procedure to test the hypothesis of no cointegration against both threshold cointegration and an intermediate possibility that we call partial cointegration. Asymptotic theory is devel- oped, the power of the proposed test is analysed through simulations and an...

Using data from the Health and Retirement Study (HRS), we make two contributions to the literature on end-of-life transfers. First, we show that unequal bequests are much more common than generally recognized, with one-third of parents with wills planning to divide their estates unequally among...

Although there is a growing interest in subjective well-being (SWB) and its determinants, the extent of socioeconomic inequalities in SWB has not yet been analyzed. This study assesses socioeconomic inequalities in SWB in twelve European countries and the United States (US), by estimating...

To confront existing fears of cultural homogeneization with development, this paper study the relationship between per capita income and the diversity in cultural imports. Two dimensions of diversity are investigated: the number of geographical origins (extensive margin) and the distribution of...

Measuring capabilities is a major challenge for the operationalization of the capability approach. Structural equation models (SEM) are being increasingly used as one possible methodology for estimating capabilities, but a certain skepticism remains about their appropriateness. In this paper, we...

This paper explores the asymmetries in price transmission from international to local markets. We expect the presence of large intermediaries in agricultural markets to lead to a stronger price transmission when international prices decline than when they rise. The empirical evidence confirms...
