Testing for a unit root in the volatility of asset returns (replication data)
It is now well established that the volatility of asset returns is time varying and highly persistent. One leading model that is used to represent these features of the data is... -
Common cycles in seasonal non-stationary time series (replication data)
This paper extends the notion of common cycles to quarterly time series having unit roots both at the zero and seasonal frequencies. It is shown that common cycles are present... -
Testing the random walk hypothesis for real exchange rates (replication data)
This paper tests the random walk hypothesis for the log-differenced monthly US real exchange rates versus some major currencies. The tests we use are variance ratio test,... -
Testing the significance of income distribution changes over the 1980s busine...
Using kernel density estimation we describe the distribution of household size-adjusted real income and how it changed over the business cycle of the 1980s in the United States... -
Estimation in large and disaggregated demand systems: an estimator for condit...
Empirical demand systems that do not impose unreasonable restrictions on preferences are typically non-linear. We show, however, that all popular systems possess the property of... -
The error structure of time series cross-section hedonic models with sporadic...
When estimating hedonic models of housing prices, the use of time series cross-section repeat sales data can provide improvements in estimator efficiency and correct for... -
Substitution, risk aversion, taste shocks and equity premia (replication data)
This paper gauges the relative contribution of risk aversion, inter-temporal substitution and taste shocks on postwar monthly US equity premia. The time-varying consumption,... -
Identifying the source of dynamics in disaggregated import data (replication ...
This paper uses Kennan's (1988) model to separately identify supply-side and demand-side dynamics in US import data. Dynamics arise from both autocorrelated shocks to supply-... -
Unemployment persistence: does the size of the shock matter? (replication data)
One of the stylized facts of unemployment is that shifts in its mean rate between decades and half-decades account for most of its variance. In this paper, we use a statistical... -
HETEROGENEITY, EXCESS ZEROS, AND THE STRUCTURE OF COUNT DATA MODELS (replicat...
This paper demonstrates that the unobserved heterogeneity commonly assumed to be the source of overdispersion in count data models has predictable implications for the... -
SEMI-PARAMETRIC ESTIMATION OF HURDLE REGRESSION MODELS WITH AN APPLICATION TO...
This paper develops a semi-parametric estimation method for hurdle (two-part) count regression models. The approach in each stage is based on Laguerre series expansion for the... -
COUNT DATA REGRESSION USING SERIES EXPANSIONS: WITH APPLICATIONS (replication...
A new class of parametric regression models for both under? and overdispersed count data is proposed. These models are based on squared polynomial expansions around a Poisson... -
On a double-threshold autoregressive heteroscedastic time series model (repli...
Tong's threshold models have been found useful in modelling nonlinearities in the conditional mean of a time series. The threshold model is extended to the so-called... -
The structure of technology in Brazilian sugarcane production, 1975–87: An ap...
Sugarcane-based ethanol has become a primary automotive fuel in Brazil over the past 15 years. Because sugarcane costs are over two-thirds of the costs of ethanol production,... -
Institutional hypothesis of the long-run income velocity of money and paramet...
It has recently been argued that when the conventional specification of M2 income velocity is extended to include proxies for two types of institutional change, as emphasized by... -
Maximum likelihood estimation of a GARCH-stable model (replication data)
Maximum likelihood is used to estimate a generalized autoregressive conditional heteroskedastic (GARCH) process where the residuals have a conditional stable distribution... -
Heterogeneity biases, distributional effects, and aggregate consumption: An e...
Using stratified microdata from the Canadian FAMEX (78-86) surveys, this paper investigates whether observed heterogeneity in marginal propensities to consume across strata...
