Optimal Taxes Under Private Information: The Role of the Inflation
We consider an overlapping generation framework with search and private information to study optimal taxation. Agents sequentially trade in markets that are characterized by different frictions and trading protocols. In frictional decentralized markets, agents receive shocks that determine if they are going to be consumers or producers. Shocks are private information. Mechanism design is used to solve for the constrained optimal allocation. We then study whether a government can replicate the constrained optimal allocation with an array of policy instruments including fiat money. We show that ...

Optimal monetary policy in a model of money and credit
The authors investigate the extent to which monetary policy can enhance the functioning of the private credit system. Specifically, they characterize the optimal return on money in the presence of credit arrangements. There is a dual role for credit: It allows buyers to trade without fiat money and also permits them to borrow against future income. However, not all traders have access to credit. As a result, there is a social role for fiat money because it allows agents to self-insure against the risk of not being able to use credit in some transactions. The authors consider a (nonlinear) ...

Nominal Exchange Rate Determinacy Under the Threat of Currency Counterfeiting
We study the endogenous choice to accept fiat objects as media of exchange and their implications for nominal exchange rate determination. We consider a two-country environment with two currencies which can be used to settle any transactions. However, currencies can be counterfeited at a fixed cost and the decision to counterfeit is private information. This induces equilibrium liquidity constraints on the currencies in circulation. We show that the threat of counterfeiting can pin down the nominal exchange rate even when the currencies are perfect substitutes, thus breaking the ...

The effects of female labor force participation on obesity
This paper assesses whether a causal relationship exists between recent increases in female labor force participation and the increased prevalence of obesity amongst women. The expansions of the Earned Income Tax Credit (EITC) in the 1980s and 1990s have been established by prior literature as having generated variation in female labor supply, particularly amongst single mothers. Here, we use this plausibly exogenous variation in female labor supply to identify the effect of labor force participation on obesity status. We use data from the National Health Interview Survey (NHIS) and replicate ...

A Financial Stress Index for a Small Open Economy: The Australian Case
We construct a Financial Stress Index (FSI) for a small open economy, which aims to provide clear and timely signals of financial market strains. This can be used in developing appropriate responses to address these adverse events. To do so, we use the principal component framework and apply it to Australian monthly data on interest rates, spreads, exchange rates, house price growth and inflation expectations. Decomposing the index into foreign and domestic components, we find that the foreign factors can explain more than half (57.4%) of our Australian Financial Stress Index (AFSI). To ...

Quantifying the shadow economy: measurement with theory
We construct a dynamic, general equilibrium model of tax evasion where agents choose to report some of their income. Unreported income requires using a payment method that avoids recordkeeping ? cash. Trade using cash to avoid taxes is the theoretical measure of the shadow economy from our model. We then calibrate our model using money, interest rate and GDP data to back out the size of the shadow economy for a sample of 30 countries and compare our estimates to traditional ad hoc estimates. Our results generate reasonably larger estimates for the size of the shadow economy than exist in ...

Optimal monetary and fiscal policies in a search theoretic model of monetary exchange
In this paper we study optimal monetary and fiscal policies, and the welfare costs of inflation, within the Lagos and Wright (2005) framework. Monetary equilibria may be inefficient without fiscal policy tools due to bargaining frictions. We show that subsidies in decentralized markets can be implemented to alleviate underproduction, while money is still essential. Deviations from the Friedman rule may be large, and having fiscal and monetary policies in place results in considerable welfare gains. When fiscal policies are held constant, the welfare costs of increasing inflation may be as ...
