This thesis investigates the consequences of model uncertainty and persistence in consumption habits and price-setting behaviour in a New Keynesian model.As the decision of a central bank is made in an uncertain environment, the analysis of uncertainty is essential in monetary policy models. In...

Intertemporal general-equilibrium models with Keynesian features such as imperfect competition and imperfectly flexible prices which give rise to a (at least) short-run non-neutrality of monetary policy have become the workhorse model for monetary macroeconomics. This thesis now makes four...

The proposition of a carbon tax has reinvigorated the discussion about the price elasticity of gasoline demand. This paper analyzes how consumers react to higher gas prices in a new setting, examining whether they choose Internet purchasing over in-store purchasing when gas prices increase....

Estimates of marginal abatement costs for reducing carbon emissions in the United States by the major economic-energy models vary by a factor of five, undermining support for mandatory policies to reduce greenhouse gas emissions. We use meta analysis to explain these cost differences, holding...

A carbon tax would penalize carbon intensive fuels like gasoline and shiftfuel consumption to less carbon intensive alternatives like biofuels. Since biofuelproduction competes for land with agriculture, a carbon tax could raiseland rents, divert land towards fuel production, and raise...

This dissertation addresses the crucial problem of how environmental policy uncertainty influences investments in energy technological change. The rising level of carbon emissions due to increasing global energy consumption calls for policy shift. In order to stem the negative consequences on...

Los diferentes elementos del diseño de una reforma fiscal verde, neutra presupuestariamente, pueden generar efectos medioambientales y económicos muy dispares. Nuestras propuestas de reforma fiscal para España pivotan en torno a un impuesto sobre el carbono que abarca todos los sectores...

Las iniciativas de fijación de precios del carbono, diseñadas para incrementar los precios relativos de los bienes y servicios intensivos en gases de efecto invernadero, no solo podrían incidir en la inflación del IPC, sino también en su volatilidad. La literatura empírica ha encontrado,...

General financial models have become workhorse models in the fields of macroeconomics and finance. These models have been developed and extensively studied by general equilibrium theorists. What makes them so applicable for macroeconomics and finance is the well accepted fact that models with a...

We quantify the effect of financial leverage on stock return volatility in a dynamic general equilibrium economy with debt and equity claims. The effect of financial leverage is studied both at a market and a firm level where the firm is exposed to both idiosyncratic and market risk. In a...
