The optimal discretionary policy rule in the New Keynesian forwardlooking model under the hypothesis of rational expectations responds only to fundamental shocks. This leads to indeterminacy of equilibria and E-unstability of the MSV REE. The outcome can be improved by responding to private...

This paper studies the optimal taxation structure and public maintenance spending in an endogenous growth model where public maintenance spending effects the efficiency of public and private capital. Private firms also spend on maintenance, which increases the effieicieny of private capital and...

This paper examines the growth effects of government expenditure for a panel of thirty developing countries over the decades of the 1970s and 1980s, with a particular focus on sectoral expenditures. Our methodology improves on previous research on this topic by explicitly recognising the role of...

This paper investigates the nature of nonlinearities in the term structure using the flexible approach to nonlinear inference. The paper reports clear evidence of nonlinearity, in contrast to the affine term structure model and consistent with recent claims in the literature. We find that there...

This paper provides evidence on the causes of movements in monthly UK stock prices, examining the role of macroeconomic and financial variables in a nonlinear framework. We allow for time-varying effects through the use of smooth transition models. We find that past changes in the dividend yield...

Existing theoretical analyses have shown that if policy variables affect investmentdecisions in either physical or human capital then an increase in policy variability results in higher trend output growth as individuals respond to higher uncertainty with a precautionary increase in these types...

This paper presents a simple stochastic growth model in which productivity improvements are the result of both internal (deliberate) and external (serendipitous) learning behaviour. The model is used to illustrate how these different mechanisms of endogenous technological change can lead to...

This paper shows that in macroeconomic models of product differentiation that are built on CES utility specifications, the widely used assumption of approximating cross price effects to zero, (since Dixit-Stiglitz 1979), plays indeed no crucial role. This is true not only when a large number of...

We show that equilibrium involuntary unemployment emerges in a multi–stage game model where all market power resides with firms, on both the labour and the output market. Firms decide wages, employment, output and prices, and under constant returns there exists a continuum of subgame perfect...

This paper studies the optimal allocation of public expenditure between infrastructure and education services in an endogenous growth framework. Raw labor must be educated to become productive. The balanced-growth path is derived and the transitional dynamics associated with an increase in the...
