Testing CAPM with a Large Number of Assets

Pesaran, M. Hashem - 2012

This paper is concerned with testing the time series implications of the capital asset pricing model (CAPM) due to Sharpe (1964) and Lintner (1965), when the number of securities, N, is large relative to the time dimension, T, of the return series. In the case of cross-sectionally correlated...

Modelling Volatilities and Conditional Correlations in Futures Markets with a Multivariate T Distribution

Pesaran, Bahram; Pesaran, M. Hashem - 2021

This paper considers a multivariate t version of the Gaussian dynamic conditional correlation (DCC) model proposed by Engle (2002), and suggests the use of devolatized returns computed as returns standardized by realized volatilities rather than by GARCH type volatility estimates. The t-DCC...

Predictability of Asset Returns and the Efficient Market Hypothesis

Pesaran, M. Hashem - 2010

This paper is concerned with empirical and theoretical basis of the Efficient Market Hypothesis (EMH). The paper begins with an overview of the statistical properties of asset returns at different frequencies (daily, weekly and monthly), and considers the evidence on return predictability, risk...

Exponent of Cross-Sectional Dependence : Estimation and Inference

Bailey, Natalia - 2012

An important issue in the analysis of cross-sectional dependence which has received renewed interest in the past few years is the need for a better understanding of the extent and nature of such cross dependencies. In this paper we focus on measures of cross-sectional dependence and how such...

Aggregation in Large Dynamic Panels

Pesaran, M. Hashem - 2011

This paper considers the problem of aggregation in the case of large linear dynamic panels, where each micro unit is potentially related to all other micro units, and where micro innovations are allowed to be cross sectionally dependent. Following Pesaran (2003), an optimal aggregate function is...

Beyond the DSGE Straitjacket

Pesaran, M. Hashem - 2011

Academic macroeconomics and the research department of central banks have come to be dominated by Dynamic, Stochastic, General Equilibrium (DSGE) models based on micro-foundations of optimising representative agents with rational expectations. We argue that the dominance of this particular sort...

An Exponential Class of Dynamic Binary Choice Panel Data Models with Fixed Effects

Al-Sadoon, Majid - 2012

This paper develops a model for dynamic binary choice panel data that allows for unobserved heterogeneity to be arbitrarily correlated with covariates. The model is of the exponential type. We derive moment conditions that enable us to eliminate the unobserved heterogeneity term and at the same...

An Empirical Growth Model for Major Oil Exporters

Esfahani, Hadi Salehi - 2012

-run output equation with a coefficient equal to the share of capital (α). The long-run theory is tested using quarterly data on … results support the long-run theory. The existence of long-run relations between real output, foreign output and real oil … steadily over the past three decades, the theory suggests that the effect of oil income on the economy's steady state growth …

Testing Weak Cross-Sectional Dependence in Large Panels

Pesaran, M. Hashem - 2012

This paper considers testing the hypothesis that errors in a panel data model are weakly cross sectionally dependent, using the exponent of cross-sectional dependence α, introduced recently in Bailey, Kapetanios and Pesaran (2012). It is shown that the implicit null of the CD test depends on...

Infinite Dimensional VARs and Factor Models

Chudik, Alexander; Pesaran, M. Hashem - 2021

This paper introduces a novel approach for dealing with the 'curse of dimensionality' in the case of large linear dynamic systems. Restrictions on the coefficients of an unrestricted VAR are proposed that are binding only in a limit as the number of endogenous variables tends to infinity. It is...
