This paper investigate the stabilization bias that arises in a model of non-cooperative monetary and fiscal policy stabilisation of the economy, when monetary authority implements price level targeting but fiscal policy remains benevolent. We demonstrate the gain in welfare improvement depends on the level of steady state debt. If the steady state level of the government debt is low, then the m...

A simple intellectual property rights (IPRs) framework is introduced into a dynamic quality ladder model of technological diffusion between innovating firms in one country and imitating firms in another country. The presence of technological spillovers and feedback effects between firms in the two countries demonstrates that, even when steady state growth increases, transition costs sometimes d...

The welfare cost of imperfect competition in the product and labor markets in the United States is quantified in a dynamic general equilibrium model. We find that the welfare cost of imperfect competition in the product market is 3.62 percent while it is 0.58 percent in the labor market, taking the transition path from the distorted to the optimal steady state into account. If we also take into...

We assume that firms actively manage risk by learning and hedging in two macroeconomic models, a simple cobweb model and a model of monopolistic competition that allows for the analysis of monetary policy and welfare. In both models, firms that learn (by paying a cost to observe the model’s stochastic shocks) face less uncertainty and produce more output than firms that hedge. Parameter or poli...
