The behavior of averaged periodograms and cross-periodograms of a broad class of nonstationary processes is studied. The processes include nonstationary ones that are fractional of any order, as well as asymptotically stationary fractional ones. The cross-periodogram can involve two...

Certain recently reported statistical regularities relating to the dispersion of firms' growth rates have begun to attract attention among IO economists. These relationships take the form of power law or scaling relationships and this has led to suggestions that the underlying mechanisms which...

Trade disputes over national product standards are a growing source of tension in the international trading system. The usual pattern is that a country introduces a new product standard for all sales of a good in its local market, which is justified as necessary for consumer or environmental...

This paper is an empirical investigation into the duration of exchange rate episodes characterized by the absence of speculative attacks. We estimate a duration model for OECD countries during the 1970-1997 period. Specifically, we use semi-parametric methods to estimate model with unrestricted...

Because the permanent incomes of parents and children are typically unobserved, the estimation of the intergenerational correlation via the use of proxy variables entails an errors-in-variables bias. By solving a system of moment equations for income observed at a given year, and a T-period...

This paper considers the impact of financial contracting on growth by exploring a model where entrepreneurs initially do R&D but subsequently need both outside investors to provide funds for capital investments and outside mangers to operate the firm efficiently some time after assets are in...

We document and then develop a model explaining and relating changes in firms'' organisation and in urban structure. Sharing of business services by headquarters and of sector-specific intermediates by production plants within a city reduces costs, while congestion increases with city size. A...

We develop and econometrically estimate a model of the location of industries across countries. The model combines factor endowments and geographical considerations, and shows how industry and country characteristics interact to determine the location of production. We estimate the model on...

We propose a new estimator for nonparametric regression based on local likelihood estimation using an estimated error score function obtained from the residuals of a preliminary nonparametric regression. We show that our estimator is asymptotically equivalent to the infeasible local maximum...

We examine the impact of US monetary policy shocks on exchange rates using the monetary policy indicator proposed by Bernanke and Mihov [Quarterly Journal of Economics, 113 (1998) 869–902]. We find evidence for instantaneous, rather than delayed, US dollar overshooting after a monetary shock...
