In an increasingly competitive environment, firms have to optimally adjust both their allocation of input factors and their technology portfolio. The latter determines economies of scope and scale in future research and production. The aim of this dissertation is to achieve better insight into...

Dynamic factor models (DFM) and dynamic stochastic general equilibrium (DSGE) models are widely used for empirical research in macroeconomics. The empirical factor literature argues that the co-movement of large panels of macroeconomic and financial data can be captured by relatively few common...

I study the evolution of aggregate volatility in the US during the postwar period by assessing the relative role played by financial shocks, technological progress, and changes in the financial system.

In the first chapter, I develop and estimate a dynamic general equilibrium model with imperfectly informed firms in the sense of Woodford (2002). The model has two aggregate shocks: a monetary policy shock and a technology shock. Firms observe idiosyncratic noisy signals about these shocks and...

Recent spikes in oil prices have thrown light on how economic activity in emerging markets may be impacted by oil price shocks. This paper conducts an empirical analysis of the effect of oil price shocks on emerging markets. It tests for the existence of an asymmetrical relationship between oil...
