The paper analyses, along the transition path and in steady state, the optimal stabilization policy in an economy in which growth is driven by learning by doing. If future benefits of learning by doing are not fully internalized by workers the optimal fiscal policy is to tax labour during...

This Paper aims at improving the understanding of the transmission of shocks across countries and how this transmission may have changed over time. By employing a model that allows for parameter changes across regimes, we show that transmission of shocks from the US to European countries may...

This paper shows that fiscal policy, when used for stabilization purposes, can have a positive effect on the economy's growth, on human capital accumulation, and on welfare, along the transition path. We introduce symmetric productivity shocks into a model in which productivity is augmented...

This paper examines the experience of 14 developed countries for which there are about 30 years of quarterly inflation-adjusted housing price data. Price dynamics is modelled as a combination of a country-specific component and a cyclical component. The cyclical component is a two-state Markov...

In February 2008, British Telecommunications (BT) introduced automatically renewing, or ‘rollover’, contracts into the UK market for fixed-voice telephone service. These contracts included a 12-month Minimum Contract Period (MCP) with associated Early Termination Charges (ETCs). Unless...

Many economists and policy analysts seem to believe that loyalty-rewarding pricing schemes, like frequent flyer programs, tend to reinforce firms' market power and hence are detrimental to consumer welfare. The existing academic literature has supported this view to some extent. In contrast, we...

This paper surveys recent work on competition in markets in which consumers face costs to switching between competing firms' products, even when all firms' products are functionally identical. I address issues in macroeconomics, international trade and industrial organization: In a market with...

Switching costs and network effects bind customers to vendors if products are incompatible, locking customers or even markets in to early choices. Lock-in hinders customers from changing suppliers in response to (predictable or unpredictable) changes in efficiency, and gives vendors lucrative ex...
