Foreign Exchange Reserves as a Tool for Capital Account Management
Many recent theoretical papers have argued that countries can insulate themselves from volatile world capital flows by using a variable tax on foreign capital as an instrument of monetary policy. But at the same time many empirical papers have argued that only rarely do we observe these cyclical capital taxes used in practice. In this paper we construct a small open economy model where the central bank can engage in sterilized foreign exchange intervention. When private agents can freely buy and sell foreign bonds, sterilized foreign exchange intervention has no effect. But we analytically ...

Ups and downs: how wages change over the business cycle
In ?Ups and Downs: How Wages Change Over the Business Cycle,? Kevin Huang discusses the shift in the cyclicality of real wages ? from countercyclical before World War II to procyclical postwar. He outlines the standard explanation for this change but offers evidence of an alternative explanation: the increased role that intermediate goods play in the production process in the postwar era.

Specific factors meet intermediate inputs: implications for strategic complementarities and persistence.
A central challenge to monetary business-cycle theory is to find a solution to the problem of persistence and delay in the real effects of monetary shocks. Previous research has identified separately specific factors and intermediate inputs as two promising mechanisms for generating the persistence and delay in a staggered price-setting framework. Models based on either of these two mechanisms have also been used in the design of optimal monetary policy. ; By examining a staggered price model that features both specific factors and intermediate inputs, the author finds an offsetting ...

International real business cycles with endogenous markup variability
The aggregate impact of decisions made at the level of the individual firm has recently attracted a lot of attention in both the macro and trade literatures. We adapt the benchmark international real business cycle model to a game-theoretic environment to add a channel for the strategic interaction among domestic and foreign firms. We show how the sum of strategic pricing decisions made at the level of the individual firm can have significant effects on the volatility and cross country co-movement of GDP and its components. Specifically we show that the addition of this one channel for ...

Land Price Dynamics and Macroeconomic Fluctuations with Imperfect Substitution in Real Estate Markets
The collateral channel, whereby an increase in residential house prices leads to an increase in commercial property prices, loosening firm borrowing constraints and leading to higher firm investment, is weaker when residential and commercial real estate are imperfect substitutes. We first show in a reduced form regression with firm level data that the strength of local zoning regulations has a negative effect on the estimated increase in firm investment following an increase in local residential real estate prices. We then modify the DSGE model of the collateral channel in Liu, Wang, and Zha ...

Temptation and self-control: some evidence and applications
This paper studies the empirical relevance of temptation and self-control using household-level data from the Consumer Expenditure Survey. We estimate an infinite-horizon consumption-savings model that allows, but does not require, temptation and self-control in preferences. To help identify the presence of temptation, we exploit an implication of the theory that a tempted individual has a preference for commitment. In the presence of temptation, the cross-sectional distribution of the wealth-consumption ratio, in addition to that of consumption growth, becomes a determinant of the ...

Production interdependence and welfare
The international welfare effects of a country?s monetary policy shocks have been controversial in the literature. While a unilateral monetary expansion increases the production efficiency in each country, it affects terms of trade in favor of one country against another depending on the currencies of price setting. We show that the increased world production interdependence magnifies the efficiency-improvement effect while dampening the terms-of-trade effect. As a consequence, a unilateral monetary expansion can be mutually beneficial and thus Pareto improving regardless of in which currency ...

Financial intermediaries, markets, and growth
In many models of financial intermediation, markets reduce welfare because they limit the amount of risk-sharing intermediaries can offer. In this paper we study a model in which markets also promote investment in a productive technology. A trade-off between risk sharing and growth arises endogenously. In the model, financial intermediaries provide insurance to households against a liquidity shock. Households can also invest directly on a financial market if they pay a cost. In equilibrium, the ability of intermediaries to share risk is constrained by the market. This can be beneficial ...

Chain of production as a monetary propagation mechanism
This paper studies a general equilibrium model with multiple stages of production and asynchronized price setting that provides a new explanation for the observed persistent real effects of monetary shocks. The key feature of the model is a vertical chain-of-production structure. In this model, the effects of monetary shocks on price adjustment are gradually dampened via the interactions of firms through their input-output relations and the timing of their price decisions. The model predicts that prices adjust by a smaller amount and less rapidly at later stages than at earlier stages, which ...

Temptation and Self-Control: Some Evidence and Applications
This paper studies the empirical relevance of temptation and self-control using household-level data from the Consumer Expenditure Survey. We construct an infinite-horizon consumption-savings model that allows, but does not require, temptation and self-control in preferences. In the presence of temptation, a wealth-consumption ratio, in addition to consumption growth, becomes a determinant of the asset-pricing kernel, and the importance of this additional pricing factor depends on the strength of temptation. To identify the presence of temptation, we exploit an implication of the theory that ...
