On the productivity advantage of cities

Agglomeration externalities are the key factor explaining the existence of cities and their size. However, while the various micro foundations of agglomeration externalities stress the importance of total factor producti...Read more...

Trade, skills and productivity

We examine how firms adjust their production and technology in response to exogenous trade shocks. We develop a model in which revenue TFP can be distinguished from quantity TFP, and where skill upgrading is explicitly e...Read more...

The slope of the Phillips Curve: evidence from US States

We estimate the slope of the Phillips curve in the cross section of U.S. states using newly constructed state-level price indices for nontradeable goods back to 1978. Our estimates indicate that the slope of the Phillips...Read more...

The UK's great demand and supply recession

We revisit UK?s poor productivity performance since the Great Recession by means of both a suitable theoretical framework and firm-level prices and quantities data for detailed products allowing us to both measure demand...Read more...

On the productivity advantage of cities

Ever since Marshall (1890) agglomeration externalities have been viewed as the key factor explaining the existence of cities and their size. However, while the various micro foundations of agglomeration externalities str...Read more...

On minimizing the risk of bias in randomized controlled trials in economics

Estimation of empirical relationships is prone to bias. Economists have carefully studied sources of bias in structural and quasi-experimental approaches, but the randomized control trial (RCT) has only begun to receive ...Read more...

Estimating strategic models of international treaty formation

This article develops an empirical framework for analysing the timing of international treaties. A treaty is modelled as a dynamic game among governments that decide on participation in every period. The net benefit of t...Read more...

Unraveling firms: demand, productivity and markups heterogeneity

We develop a novel framework that simultaneously allows recovering heterogeneity in demand, quantity TFP and markups across firms while leaving the correlation between the three dimensions unrestricted. We accomplish thi...Read more...

European integration and the gains from trade

This chapter discusses whether and how .new quantitative trade models.(NQTMs) can be fruitfully applied to quantify the welfare effects of trade liberalization, thus shedding light on the trade-related effects of further...Read more...

Free to choose? The impact of healthcare reform

Has the introduction of greater choice and competition in healthcare in England led to improved outcomes for patients? The authors assess changes in the quality of care that hospitals provided for cardiac surgery patient...Read more...

Estimating Bayesian decision problems with heterogeneous priors

In many areas of economics there is a growing interest in how expertise and preferences drive individual and group decision making under uncertainty. Increasingly, we wish to estimate such models to quantify which of the...Read more...

Productivity As If Space Mattered: An Application to Factor Markets Across China

Optimal production decisions depend on local market characteristics. This paper develops a model to explain firm labor demand and firm density across regions. Firms vary in their technology to combine imperfectly substit...Read more...

Free to Choose? Reform and Demand Response in the English National Health Service

The impacts of choice in public services are controversial. We exploit a reform in the English National Health Service to assess the impact of relaxing constraints on patient choice. We estimate a demand model to evaluat...Read more...

Homeownerhip and Entrepreneurship

We study the link between homeownership and entrepreneurship by exploiting the longitudinal dimension of the British Household Panel Survey (BHPS) and constructing a detailed monthly-spell dataset that tracks individuals...Read more...

Autoregressions in Small Samples, Priors about Observables and Initial Conditions

We propose a benchmark prior for the estimation of vector autoregressions: a prior about initial growth rates of the modelled series. We first show that the Bayesian vs frequentist small sample bias controversy is driven...Read more...

Leveraging Monopoly Power by Degrading Interoperability: Theory and Evidence from Computer Markets

When will a monopolist have incentives to leverage his market power in a primary market to foreclose competition in a complementary market by degrading compatibility/interoperability of his products with those of her riv...Read more...

The Penn-Belassa-Samuelson Effect in Developing Countries: Price and Income Revisited

It is conventional wisdom that richer countries have a higher price level than poorer countries. This paper provides evidence that the price-income relationship is non-linear and that it turns negative, or at best flat, ...Read more...

Recovering the Sunk Costs of R&D: the Moulds Industry Case

Sunk costs for R&D are an important determinant of the level of innovation in the economy. In this paper I recover them using a Markov equilibrium framework. The contribution is twofold. First, a model of industry dynami...Read more...

On the Existence of the Maximum Likelihood Estimates for Poisson Regression

We note that the existence of the maximum likelihood estimates for Poisson regression depends on the data configuration. Because standard software does not check for this problem, the practitioner may be surprised to fin...Read more...

Tax Cuts in Open Economies

A reduction in income tax rates generates substantial dynamic responses within the framework of the standard neoclassical growth model. The short-run revenue loss after an income tax cut is partly - or, depending on para...Read more...

Zipfs Law for Cities: An Empirical Examination

We use data for metro areas in the United States, from the US Census for 1900 u 1990, to test the validity of Zipf's Law for cities. Previous investigations are restricted to regressions of log size against log rank. In...Read more...
