We calculate the effects of an increase in government spending financed with labor income taxes or inflation. We consider government spending in the form of government consumption or transfers. We use a model in which agents increase the use of financial services to avoid losses from inflation,...

We find that the Friedman rule is not optimal with real government transfers and distortionary taxation. As transfers cannot be taxed, a positive nominal net interest rate is the indirect way to tax the additional income derived from transfers. This result holds for heterogeneous agents,...

Firm cash holdings increased substantially from 1980 to 2017. We study the implications of the increase in firm cash holdings on monetary policy. We introduce a model that takes the distribution of firm cash holdings as an input. We find that the interest rate channel of the transmission of...

We calculate the effects of an increase in government spending financed with labor income taxes or inflation. Government spending takes the form of government consumption or transfers. Agents increase the use of financial services to avoid losses from inflation. The financial sector increases...

We find that the Friedman rule is not optimal with government transfers and distortionary taxation. This result holds for heterogeneous agents, standard homogeneous preferences, and constant returns to scale production functions. The presence of transfers changes the standard optimal taxation...

We study the effect of technological progress on the optimal transition to a renewable energy-fueled world economy. We develop a dynamic general equilibrium model where energy is used as an input in production and can come from fossil or renewable sources. Both require the use of capital, which...

How can a particular allocation and prices be implemented? Under what conditions does a policy deliver a unique competitive equilibrium? How many degrees of freedom there are in the determination of the policy variables, or how many are the instruments of policy? In this paper we analyze a...

The options premiums are frequently used to obtain probability density functions (pdfs) for the prices of the underlying assets. When these assets are bank deposits or notional Government bonds it is possible to compute probability measures of future interest rates. Recently, in the literature...
