The limiting distributions of two unit-root test statistics are derived and discussed for data that have both cross-sectional and time-series dimensions.

We study the problem of ?finding the worst-case joint distribution of a set of risk factors given prescribed multivariate marginals and a nonlinear loss function. We show that when the risk measure is CVaR, and the distributions are discretized, the problem can be conveniently solved using...

Numerical challenges inherent in algorithms for computing worst Value-at-Risk in homogeneous portfolios are identified and words of warning concerning their implementation are raised. Furthermore, both conceptual and computational improvements to the Rearrangement Algorithm for approximating...

This paper estimates and tests several versions of the consumption-based asset pricing model extended to allow for time-nonseparable preferences and/or liquidity constraint proxies, using Canadian aggregate data. It is found that a habit-persistence effect uncovered in the time-nonseparable...

This paper tests the prediction of the Permanent Income Hypothesis (PIH) that news about future income induce a revision in consumption equal to the revision in permanent income. We use time-series data from 48 contiguous US states to perform the test. The empirical results provide some support...

Volatility clustering is a well-known stylized feature of financial asset returns. In this paper, we investigate the asymmetric pattern of volatility clustering on both the stock and foreign exchange rate markets. To this end, we employ copula-based semi-parametric univariate time-series models...

Building on recent advances in the theory of the optimal timing of investment under uncertainty, this paper proposes a stylized theoretical model to study an individual's optimal migration strategy. It shows that, as a result of following the optimal strategy, the individual may choose to delay...

Recently Wang and Wirjanto (1997) proposed a simple dynamic model to study the optimal timing strategy for an individual's migration decision, using the theory of the optimal timing of investment under uncertainty, reviewed in Dixit (1992), Dixit and Pindyck (1994), and Pindyck (1991). It is...
