Using brand-level retail data, the firm size distribution in carbonated soft drinks is shown to be an outcome of the degree to which firms have placed brands effectively (store coverage) across vertical (flavour, packaging, diet attributes) segments of the market. Regularity of the firm size...

This paper shows that smoking intensity, i.e. the amount of nicotine extracted per cigarette smoked, responds to changes in excise taxes and tobacco prices. We exploit NHANES data covering the period 1988 to 2006 across many US states. Moreover, using panel data from the Coronary Artery Risk...

There is a growing consensus among economists that extending shop opening hours creates jobs. While this is probably true in deregulating industries, this paper argues there are some deficiencies in the existing hypotheses about how exactly deregulation affects employment. First, this paper...

During the past few decades a number of European countries lifted the regulations that restricted the opening hours of shops on Sunday. In this paper we examine the impact of Sunday trade deregulation on employment, expenditure, prices and market structure using a difference-in-difference...

This paper examines the frequency, pervasiveness, and determinants of product switching by US manufacturing firms. We find that one-half of firms alter their mix of five-digit SIC products every five years, that product switching is correlated with both firm- and firm-product attributes, and...

We estimate a structural model of heterogeneous multiproduct firms to examine the sources of firm heterogeneity emphasized in the recent trade and macro literatures. Using Nielsen barcode data on prices and sales, we estimate elasticities of substitution within and between firms, and use the...

This paper presents a game theoretic analysis of the generalized second-price auction that the company Overture operated in 2004 to sell sponsored search listings on search engines. We construct a model that embodies few prior assumptions about parameters, and we present results that indicate...

This paper tests for the importance of cash flow on investment in fixed capital and R&D using firm-level panel data in two countries between 1985 and 1994. For German firms, cash flow is not informative in simple econometric models of fixed investment or R&D. In identical specifications for...

This paper gives a general framework for analysing a trade divergence that runs across both the New International trade theory and the traditional analysis of export policy. The source of the trade divergence, the motive for intervention and the analytical framework is shown to be the same in...
