This paper presents a dynamic general equilibrium model of trade between two advanced countries in which both innovation and skilled acquisition rates are endogenously determined. The model offers a North-North (as opposed to a North-South) trade explanation for increasing relative wage...

This paper calls into question the currently most influential model of international trade. An empirical finding by Trefler (2004, AER) and others that industrial productivity increases more strongly in liberalized industries than in non-liberalized industries has been widely accepted as...

This paper presents a model to explain why both industry leaders and follower firms often invest in R&D and explores the welfare implications of these R&D investment choices. Regardless of initial conditions, the equilibrium path in this model involves gradually convergence to a balanced growth...

This paper presents a model of R&D-driven growth without scale effects where firms can engage in both horizontal and vertical R&D activities. Unlike in earlier models of R&D-driven growth without scale effects by Jones (1995), Segerstrom (1998) and Young (1998), R&D subsidies can have long-run...

In this paper, we present a standard quality ladders endogenous growth model with one significant new assumption, that it takes time for firms to learn how to export. We show that this model without Melitz-type assumptions can account for all the evidence that the Melitz (2003) model was...

A common assumption in the Schumpeterian growth literature is that the innovation size is constant and identical across industries. This is in contrast with the empirical evidence which shows that: (i) the innovation size is far from being identical across industries; a (ii) the size...

In this paper we construct analytical estimates of the elasticity of VAT revenues with respect to underlying gross income and expenditure for Ireland. The responsiveness of VAT revenue from households in Ireland to changes in household gross income steadily increased up to the late 2000s. The...

In this paper we examine the elasticity of Irish income taxation revenue with respect to aggregate national output - both GDP and GNP. This enables us to estimate the sensitivity of this key taxation aggregate with respect to changes in economic activity. It also allows us to compare the...
