Time-varying risk, interest rates and exchange rates in general equilibrium
Time-varying risk is the primary force driving nominal interest rate differentials on currency-denominated bonds. This finding is an immediate implication of the fact that exchange rates are roughly random walks. We show that a general equilibrium monetary model with an endogenous source of risk variation?a variable degree of asset market segmentation?can produce key features of actual interest rates and exchange rates. The endogenous segmentation arises from a fixed cost for agents to exchange money for assets. As inflation varies, the benefit of asset market participation varies, and that ...
Quantitative asset pricing implications of endogenous solvency constraints
The authors study the asset pricing implications of an economy where solvency constraints are determined to efficiently deter agents from defaulting. The authors present a simple example for which efficient allocations and all equilibrium elements are characterized analytically. The main model produces large equity premia and risk premia for long-term bonds with low risk aversion and a plausibly calibrated income process. The authors characterize the deviations from independence of aggregate and individual income uncertainty that produce equity and term premia.
The Risk of Becoming Risk Averse: A Model of Asset Pricing and Trade Volumes
We develop a new general equilibrium model of asset pricing and asset trading volume in which agents? motivations to trade arise due to uninsurable idiosyncratic shocks to agents? risk tolerance. In response to these shocks, agents trade to rebalance their portfolios between risky and riskless assets. We study a positive question ? When does trade volume become a pricing factor? ? and a normative question ? What is the impact of Tobin taxes on asset trading on welfare? In our model, economies in which marketwide risk tolerance is negatively correlated with trade volume have a higher risk ...
Money, interest rates, and exchange rates with endogenously segmented markets
This paper analyzes the effects of money injections on interest rates and exchange rates in a model in which agents must pay a Baumol-Tobin style fixed cost to exchange bonds and money. Asset markets are endogenously segmented because this fixed cost leads agents to trade bonds and money only infrequently. When the government injects money through an open market operation, only those agents that are currently trading absorb these injections. Through their impact on these agents? consumption, these money injections affect real interest rates and real exchange rates. We show that the model ...
The time consistency of monetary and fiscal policies
Are optimal monetary and fiscal policies time consistent in a monetary economy? Yes, but if and only if under commitment the Friedman rule of setting nominal interest rates to zero is optimal. This result is of applied interest because the Friedman rule is optimal for the standard preferences used in applied work, those consistent with the growth facts. (Replaced by Staff Report No: 305)
Money and interest rates with endogeneously segmented markets
This paper analyses the effects of open market operations on interest rates in a model in which agents must pay a fixed cost to exchange assets and cash. Asset markets are endogenously segmented in that some agents choose to pay the fixed cost and some do not. When the fixed cost is zero, the model reduces to the standard one in which persistent money injections increase nominal interest rates, flatten the yield curve, and lead to a downward-sloping yield curve on average. In contrast, if markets are sufficiently segmented, then persistent money injections decrease interest rates, steepen or ...
Fixed term employment contracts in an equilibrium search model
Fixed term employment contracts have been introduced in number of European countries as a way to provide flexibility to economies with high employment protection levels. We introduce these contracts into the equilibrium search model in Alvarez and Veracierto (1999), a version of the Lucas and Prescott island model, adapted to have undirected search and variable labor force participation. We model a contract of length J as a tax on separations of workers with tenure higher than J. We show a version of the welfare theorems, and characterize the efficient allocations. This requires solving a ...
If exchange rates are random walks then almost everything we say about monetary policy is wrong
The key question asked by standard monetary models used for policy analysis is how do changes in short term interest rates affect the economy. All of the standard models imply that such changes in interest rates affect the economy by altering the conditional means of the macroeconomic aggregates and have no effect on the conditional variances of these aggregates. We argue that the data on exchange rates imply nearly the opposite: fluctuations in interest rates are associated with nearly one-for-one changes in conditional variances and nearly no changes in conditional means. In this sense ...
