A new semiparametric estimator for an empirical asset pricing model with general nonparametric risk-return tradeoff and a GARCH process for the underlying volatility is introduced. The estimator does not rely on any initial parametric estimator of the conditional mean function, and this feature...

We extend the fractionally integrated exponential GARCH (FIEGARCH) model for daily stock return data with long memory in return volatility of Bollerslev and Mikkelsen (1996) by introducing a possible volatility-in-mean effect. To avoid that the long memory property of volatility carries over to...

We study the forecasting of future realized volatility in the stock, bond, and foreign exchange markets, as well as the continuous sample path and jump components of this, from variables in the information set, including implied volatility backed out from option prices. Recent nonparametric...

All countries would agree to immediate global free trade if countries were compensated for any terms-of-trade losses with transfers from countries whose terms-of-trade improve, and if customs unions were required to have no effects on non-member countries. Global free trade with transfers is in...

AbstractChanges in trade policy affect a nation's economic welfare through terms-of-trade and volume-of-trade effects. A move to global free trade would imply higher world economic welfare equal to the sum of all nations' volume-of-trade, or efficiency, effects. Since the sum of the...

This paper shows nonemptiness of the core of a customs union game with a status quo equilibrium with tariffs by employing an appropriate notion of the core as in <link rid="b9">Kowalczyk and Sjöström (1994</link>, <i>Economica</i>). Specifically, we find that if customs unions may have no effects on nonmember countries as...
