This paper considers forecast averaging when the same model is used but estimation is carried out over different estimation windows. It develops theoretical results for random walks when their drift and/or volatility are subject to one or more structural breaks. It is shown that compared to...

In this paper we reexamine the Feldstein-Horioka finding of limited international capital mobility by using a broader view (i.e., including human capital) of investment and saving. We find that the Feldstein-Horioka result is impervious to this change

The standard tax theory result that investment should not be distorted is based on the assumption that profits are locally bound. In this paper we analyze the optimal tax policy when firms are internationally mobile. We show that the optimal policy response to increasing firm mobility may be...

I analyze the dynamic effects of tax competition on public budget deficits. I find that stronger tax competition leads to a fiscal deficit bias at the early stages of financial liberalization. When countries differ in terms of capital mobility, further liberalization leads to external imbalances...

This paper studies theoretically and empirically competition in commodity taxation and product market regulation between trading partner countries. We present a two-country general equilibrium model in which destination-based commodity taxes finance public goods, and product market regulation...

We analyze Pareto-efficient tax breaks for personal taxation in a private information environment. In addition to a labor-leisure choice, the agents decide how to spend their money between consumption and work-related goods. We derive an efficiency condition that relates the rate of tax...

This paper analyses the long-memory properties of a high-frequency financial time series dataset. It focuses on temporal aggregation and other features of the data, and how they might affect the degree of dependence of the series. Fractional integration or I(d) models are estimated with a...
