Volatility clustering is a well-known stylized feature of financial asset returns. This paper investigates asymmetric pattern in volatility clustering by employing a univariate copula approach of Chen and Fan (2006). Using daily realized kernel volatilities constructed from high frequency data...

Selecting an estimator for the covariance matrix of a regression's parameter estimates is an important step in hypothesis testing. From less to more robust estimators, the choices available to researchers include Eicker/White heteroskedasticity-robust estimator, cluster-robust estimator, and...

This paper considers a general permanent-income model in which a fraction of consumers in the economy is liquidity constrained. Consumption growth rate for these individuals is related to the growth rate of their income and the level of real interest rates. The interest-rate coefficient is...

In a recent paper Mercenier and Sekkat (1988) conclude that the Bank of Canada has followed a policy of exchange rate targeting using the money supply. We reexamine their results using a different estimation approach and with different assumptions about the forcing process of the exogenous...

This paper implements empirical tests of the recently proposed float-adjusted return model by using Chinese stock-market data. The results show that variation in free float can explain cross-sectional variation in asset returns by about 6.7% annually, after we control for market risk, size, and...

A copula approach is used to examine the extreme return-volume relationship in six emerging East-Asian equity markets. The empirical results indicate that there is significant and asymmetric return-volume dependence at extremes for these markets. In particular, extremely high returns (large...

There is a substantial empirical literature which examines the relationship between private and public consumption. The conclusions from this literature, however, are generally mixed. In this paper, we attempt to provide some additional evidence on this relationship. We consider a two-good...

In this paper, we study intraperiod and intertemporal substitution in U.S. import demand using a two-good version of the permanent-income model that allows for nonseparability between domestic and imported goods consumption. The intratemporal elasticity of substitution between the two goods is...

The paper investigates whether there are variants of the permanent income model which are consistent with quarterly, seasonally unadjusted post-war Canadian data. The model estimates about 20 percent of consumers follow the rule of thumb of consuming their current income. This suggests a large...
