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...

In recent literature on monetary policy and learning, it has been suggested that private sector’s expectations should play a role in the policy rule implemented by the central bank, as they could improve the ability of the policymaker to stabilize the economy. Private sector’s expectations,...

We consider a multi–sector overlapping generations model with oligopolistic firms in the output markets and wage–setting trade unions in the labour markets. A coordination problem between firms creates multiple temporary equilibria which are either Walrasian or of the Keynesian unemployment...

This paper tests the proposition that fiscal transparency, measured by a newly constructed data on budget openness, can be a powerful control on corruption. This result is robust to the choice of index of corruption, conditioning variables, country sample, exclusion of outliers, and the use of...

We study affiliations for the countries of the European Economic and Monetary Union (EMU) with Germany and the US, using various business cycle measures derived from quarterly real GDP. These measures are Hodrick-Prescott and Baxter-King filtered series, together with annual and quarterly growth...

This paper extends the literature on economic growth and demographic change by developing a neo-classical model of endogenous growth in which both economic and demographic outcomes are jointly determined. The key point in this model is the endogenisation of child mortality rate by linking it to...

This paper empirically models the relationship between quarterly business cycle movements in the US and the other G7 countries, including an analysis of the US with a European (E15) aggregate. By using a nonlinear smooth transition vector autoregressive framework, the possibility of asymmetric...
