The paper studies the interaction between aggregation and persistence pertaining to skip sampling of stock variables as well as temporal aggregation of flow variables for the generalized fractional processes. We show that, for skip sampling, the long memory feature at the zero frequency can...

In this paper we propose a new methodology in improving the Diffusion Index forecasting model (Stock and Watson, 2002a, 2002b) using hard thresholding with robust KVB statistic for regression hypothesis tests (Kiefer et al., 2000). The new method yields promising results in the context of long...

We proposed a method to estimate extreme conditional quantiles by combining quantile GARCH model of Xiao and Koenker (2009) and extreme value theory (EVT) approach. We first estimate the latent volatility process using the information of intermediate quantiles. We then apply EVT to the tail...

This paper employs panel methods that address/mitigate heterogeneity and cross-sectional dependence to determine the direction and sign of long-run causality between transport energy consumption per capita and real GDP per capita. Granger-causality was determined to run from GDP to energy.

In this paper we consider the problem of interpreting the signs of the estimated coefficients in multivariate time series regressions where the regressors are correlated. Using a continuous time model, we argue that focusing on the signs of individual coefficients in such regressions could be...

Two-step estimation with large panel data sets generally involves estimating vectors of individual-specific coefficients in a first-stage. In a second-stage estimation a vector of estimated coefficients is used as the dependent variable. Potential problems of heteroskedasticity in the second...

It is shown in this paper that there exist cost innovations for which a monopolist has a higher incentive to invest than a social planner. This unveils the limits of the claim, based on Arrow (1959), that a monopoly always has a lower incentive to innovate than a social planner and therefore...

According to the well-known “merger paradox”, in a Cournot market game mergers are generally unprofitable unless most firms merge. The present paper proposes an optimal merger mechanism. With this mechanism mergers are never unprofitable, more profitable than in other known mechanisms, and...

We show that a seasonal good could be priced countercyclically due to the heterogeneous seasonal shifts in consumer valuations. We provide empirical support for our explanation based on two product categories (canned soup and tuna) studied in the literature.

This paper explores the relation between vertical disintegration and the co-localization of knowledge intensive business service (Kibs) firms in the metropolitan region of Milan, using micro-geographic data and nonparametric methods. Our main results are that: (i) compared to other manufacturing...
