If a consumer wishes to protect her retirement account from the risk of price changes in order to sustain a stable standard of living, then what price index should the account be indexed to? This paper constructs a dynamic price index (DPI) that answers this question. Unlike the existing theory...

This paper uses a dynamic factor model for the quarterly changes in consumption goods’ prices to separate them into three components: idiosyncratic relative-price changes, aggregate relative-price changes, and changes in the unit of account. The model identifies a measure of “pure”...

In this Paper we propose an alternative to traditional hedonics for estimating new multiunit housing inflation, adjusting for quality changes. By relying on the within-site variation we control in a very general way for unobserved housing characteristics using site-specific effects. Precise...

This paper investigates spatial variations in product prices using an exhaustive micro dataset on fish transactions. The data record all transactions between vessels and wholesalers that occur on local fish markets in France during the year 2007. Spatial disparities in fish prices are sizable,...

This paper exploits the 2008-09 stamp duty holiday in the United Kingdom to estimate the incidence of a transaction tax on housing. The average reduction in the after-tax sale price is found to be around £900 against the backdrop of an average tax reduction of about £1500. While we estimate an...

This Paper examines the importance of the distribution of consumers in Hotelling's circle on the comparison between the optimal and the market equilibrium levels of diversity. It finds that when most consumers are located very close to the firms, the result of Salop that the equilibrium number...

This Paper studies the theoretical micro-foundations of urban agglomeration economies. We distinguish three types of micro-foundations, based on sharing, matching, and learning mechanisms. For each of these three categories, we develop one or more core models in detail and discuss the literature...

When firms cluster in the same local labour market, they face a trade-off between the benefits of labour pooling (i.e., access to workers whose knowledge helps reduce costs) and the costs of labour poaching (i.e., loss of some key workers to competition and the indirect effect of a higher wage...

We re-examine the economic justification for the regulation of firms' spatial price policies. Existing analysis, by treating market structure as exogenous, loses an important trade-off. Discriminatory pricing is more competitive between incumbents but acts as a strong deterrent against entry....

Transport costs play a key role in agricultural markets in developing countries and are one of the causes of poverty amongst farmers that are geographically isolated. Another characteristic of agricultural markets is that they often involve interlinked transactions. However, the existing...
