Our model studies the evolution of productivity growth in a competitive industry. The exogenous wage rate determines the firms' engagement in labour productivity enhancing process innovation. There is a unique steady state of the industry dynamics, which is globally stable. In the steady state,...

In a market with short term agents and heterogeneous information, when liquidity trading displays persistence, prices reflect average expectations about fundamentals and liquidity trading. Informed investors exploit a private learning channel to infer the demand of liquidity traders from the...

Central banks' projections--i.e. forecasts conditional on a given interest rate path-- are often criticized on the grounds that their underlying policy assumptions are inconsistent with the existence of a unique equilibrium in many forward-looking models. Here I describe three alternative...

We study the incentives to improve ability in a model where heterogeneous firms and workers interact in a labor market characterized by matching frictions and costly screening. When effort in improving ability raises both the mean and the variance of the resulting ability distribution, multiple...

In the context of revived output growth and business confidence in the UK, we analyse forward guidance as a ‘coordination device’, indicating that monetary accommodation will be available for a welcome and long-awaited shift out of prolonged recession. As David Miles has emphasised, however,...

We study workplace peer effects in fertility decisions using a game theory model of strategic interactions among coworkers that allows for multiple equilibria. Using register-based data on fertile-aged women working in medium sized establishments in Denmark, we uncover negative average peer...

Periods of low household wealth in United States macroeconomic history have also been periods of high business cycle volatility. This paper develops a simple model that can exhibit self-fulfilling fluctuations in the expected path for unemployment. The novel feature is that the scope for...

We analyse the implications for the dynamics of capital accumulation of market power and endogenous demand elasticities, in an environment in which the latter are affected by the number of competitors in each industry. In equilibrium the interest rate increases as capital accumulates, even...

This paper considers a simple model of self-fulfilling expectations that leads to a multiple equilibrium of gender gaps in wages and participation rates. Rather than resorting to moral hazard problems related to unobservable effort, like in most of the related literature, our model fully relies...

This paper reviews the new economic geography literature, which accounts for the uneven distribution of economic activity across space in terms of a combination of love of variety preferences, increasing returns to scale and transport costs. After outlining the canonical core and periphery...
