We construct a two sector general equilibrium model in which one sector produces a homogeneous good and the other sector produces a vertically differentiated good. We demonstrate that uniform (across sectors) and (Hicks) neutral technologies change can cause an increase in the skill premium.

In this paper we use a model of vertical product differentiation to cast doubt on the general validity of the import demand function as specified in macroeconomic models. The empiricai importance of our theoretical concerns is then examined with the aid of two hypotheses. According to the first...

The macroeconomic effects on growth, investment and private sector employment of different ways of rolling back the welfare state are analysed. Cutting public spending on private goods induces a lower interest rate, a higher wage, a lower capital stock and a fall in employment. Cutting public...

Making use of restrictions imposed by equilibrium, theoretical progress has been made on the nonparametric and semiparametric estimation and identification of scalar additive hedonic models (Ekeland, Heckman, and Nesheim, 2002) and scalar nonadditive hedonic models (Heckman, Matzkin, and...

This paper considers the identification and estimation of hedonic models. We establish that in an additive version of the hedonic model, technology and preferences are generically identified up to affine transformations from data on demand and supply in a single hedonic market. For a very...

In this paper we argue that strong political economy forces explain the rush of the EU to expand eastwards. We use a model of vertical product differentiation in order to claim that technologically- advanced EU firms (residing in high-income member countries) prefer a mutual market-opening with...
