The aggregate Lerner index is a popular composite measure of multi-product banks' market power, based on the assumption that banks' single aggregate output factor is total assets. This study identifies three limitations of the aggregate Lerner index that potentially distort its interpretation as...

The economic literature has largely ignored the existence of global common factors and local spatial dependence in the assessment of the real effects of U.S. banking deregulation. Motivated by consistency concerns, this study uses spatial econometric models with common factors to analyze the...

This paper focuses on the exposure of common stocks to inflation risk and assesses the impact of this exposure on portfolio choice. We show that the relation between real stock returns and inflation rates, as well as the parameter uncertainty involved with this relation, has substantial...

This paper analyzes mean reversion in international stock markets during the years 1900 – 2009, using annual data. Our panel of stock indices in 18 OECD countries allows us to analyze in detail the dynamics of the mean-reversion process. In the period 1900 – 2009 it takes stock prices about...

This paper analyzes mean reversion in international stock markets during the period 1900-2008, using annual data. Our panel of stock indexes in seventeen developed countries, covering a time span of more than a century, allows us to analyze in detail the dynamics of the mean-reversion process....

This article proposes a method to estimate a sufficient loss reserve for insurance companies, such that they can cover income insurance claims filed by self-employed workers. The first step involves a multistate mixed proportional hazards (MPH) approach to model self-employed workers' disability...

This paper discusses the implications of mean reversion in stock prices for long-term investors such as pension funds. We start with a general definition of a mean-reverting price process and explain how mean reversion in stock prices is related to mean reversion in stock returns. Subsequently,...

We study the multi-period asset allocation problem for emerging-market investors whose asset menu consists of stocks, bonds and bills. We consider two types of investors: domestic investors who invest in emerging-market assets only (with returns in local currency) and international investors who...

When the ARMA-GARCH model errors lack a finite fourth moment, the asymptotic distribution of the quasi-maximum likelihood estimator may not be Normal. In such a scenario the conventional bootstrap turns out inconsistent. Surprisingly, simulations show that the conventional bootstrap, despite its...

We estimate the myopic (single-period) and intertemporal hedging (long-run) demand for stocks in 20 growth-leading emerging market economies and the US during the 1999-2012 period. We consider two types of emerging market investors: a domestic investor (whose returns are denominated in the local...
