We consider an observer who makes a finite number of observations of an industry producing a homogeneous good, where each observation consists of the market price and firm specific production quantities.  We develop a revealed preference test (in the form of a linear program) for the hypothesis...

Productivity is high in cities partly because the urban environment acts as a self-selection mechanism.  If workers have imperfect information about the quality of workers with whom they match and matches take place within cities, then high-ability workers will choose to live and work in...

Although a general unrestricted model may under-specify the data generation process, especially when breaks occur, model selection can still improve over estimating a prior specification.  Impulse-indicator saturation (IIS) can 'correct' non-constant intercepts induced by location shifts in...

This paper incorporates Nash bargaining, credible bargaining and efficiency wages as special cases of an over-arching model of wage determination in a matching model that is used to assess econometrically how well each fits US data.  With Nash bargaining, estimates for worker bargaining power...

The new-Keynesian Phillips curve (NKPC) includes expected future inflation as a major feedforward variable to explain current inflation.  Models of this type are regularly estimated by replacing the expected value by the actual future outcome, then using Instrumental Variables or Generalized...

This paper builds a dynamic stochastic general equilibrium (DSGE) model of endogenous growth that is capable of generating substantial degrees of endogenous persistence in productivity.  When products go out of patent protection, the rush of entry into their production destroys incentives for...

This paper surveys the most popular parametric and semi-parametric estimators for Cobb-Douglas production functions arising from the econometric literature of the past two decades. We focus on the different approaches dealing with 'transmission bias' in firm-level studies, which arises from...

The consumption behaviour of UK, US and Japanese households is examined and compared using a modern Ando-Modigliani style consumption function.  The models incorporate income growth expectations, income uncertainty, housing collateral and other credit effects.  These models therefore capture...

The paper examines the contentious issue of the extent of surplus labour that remains in China.  China was an extreme example of a surplus labour economy, but the rapid economic growth during the period of economic reform requires a reassessment of whether the second stage of the Lewis model...

We consider information from many sciences bearing on the causes and consequences of climate change, focusing on lessons from past mass extinctions of life on Earth.  The increasing atmospheric levels of the main greenhouse gases are now established, as is their source in human activity. ...
