Climate change must deal with two market failures: global warming and learning by doing in renewable use. The first-best policy consists of an aggressive renewables subsidy in the near term and a gradually rising and falling carbon tax. Given that global carbon taxes remain elusive, policy...

There is growing interest in multi-sector models that combine aggregate balanced growth, consistent with the well-known Kaldor facts, with systematic changes in the sectoral allocation of resources, consistent with the Kuznets facts. Although variations in the income elasticity of demand across...

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...

The paper proposes a simple equilibrium model of venture capital, entrepreneurship and innovation. Venture capitalists not only finance but also advise start-up entrepreneurs and thereby add value to new firms. The paper demonstrates how a productive and active VC industry boosts innovation...

The paper develops a unified general equilibrium model including savings with overlapping generations, investment and search unemployment. Long-run analytical results for the small open economy identify capital accumulation as a prime transmission channel. The effects of integration on...

Democratic countries with substantial inequality and where people believe that success depends on connections and luck induce political support for high tax rates and generous welfare states. Traditional wisdom is that such policies harm the economy, but there is not much evidence that countries...

We consider the evolution of preferences when trade occurs between two countries. We show that if one country is much larger than the other, its preferences can eventually take over the preferences of the second country. This result may provide an explanation of why small countries sometimes...
