This paper considers the Granger-causality in conditional quantile and examines the potential of improving conditional quantile forecasting by accounting for such a causal relationship between financial markets. We consider Granger-causality in distributions by testing whether the copula...

In prediction of quantiles of daily S&P 500 returns we consider how we use high-frequency 5-minute data. We examine methods that incorporate the high frequency information either indirectly through combining forecasts (using forecasts generated from returns sampled at different intra-day...

When the observed price process is the true underlying price process plus microstructure noise, it is known that realized volatility (RV) estimates will be overwhelmed by the noise when the sampling frequency approaches infinity. Therefore, it may be optimal to sample less frequently, and...

This paper makes a simple but previously neglected point with regard to an empirical application of the test of White (1989) and Lee, White and Granger (LWG, 1993), for neglected nonlinearity in conditional mean, using the feedforward single layer artificial neural network (ANN). Because the...

In the context of a standard one-sector AK model of endogenous growth, we show that the economy exhibits equilibrium indeterminacy and belief-driven aggregate fluctuations under progressive taxation of income. When the tax schedule is regressive or flat, the economy's balanced growth path...

Patient preferences have a social welfare interpretation consonant with a belief that the society affected by present decisions will last for a very long time. In stochastic settings, these preferences lead to justifications for variants of the precautionary principle.

Abstract. In many economic, political and social situations, circumstances change at random points in time, reacting is costly, and reactions appropri- ate to present circumstances may become inappropriate upon future changes, requiring further costly reaction. Waiting is informative if arrival...

The current regression models for interval-valued data ignore the extreme nature of the lower and upper bounds of intervals. We propose a new estimation approach that considers the bounds of the interval as realizations of the max/min order statistics coming from a sample of n_t random draws...

Eusepi (2009, International Journal of Economic Theory 5, pp. 9-23) analytically Önds that a one-sector real business cycle model may exhibit positive co-movement between con- sumption and investment when the equilibrium wage-hours locus is positively-sloped and steeper than the...

Despite using a variety of models and assumptions, the existing literature has overwhelmingly concluded that education policy should be regressive. In this paper, we examine a two-period model in which the government may impose non- linear taxes on both labour income and education expenditures....
