Innovation and growth with financial, and other, frictions

The generation and implementation of ideas, or knowledge, is crucial for economic performance. We study this process in a model of endogenous growth with frictions. Productivity increases with knowledge, which advances via innovation, and with the exchange of ideas from those who generate them to those best able to implement them (technology transfer). But frictions in this market?including search, bargaining, and commitment problems?impede exchange and thus slow growth. We characterize optimal policies to subsidize research and trade in ideas, given both knowledge and search externalities. ...

Inflation dynamics during the financial crisis

Firms with limited internal liquidity significantly increased prices in 2008, while their liquidity unconstrained counterparts slashed prices. Differences in the firms' price-setting behavior were concentrated in sectors likely characterized by customer markets. The authors develop a model in which firms face financial frictions while setting prices in a customer-markets setting. Financial distortions create an incentive for firms to raise prices in response to adverse demand or financial shocks. These results reflect the firms' reaction to preserve internal liquidity and avoid accessing ...

A model of the Twin Ds: optimal default and devaluation

This paper characterizes jointly optimal default and exchange-rate policy in a small open economy with limited enforcement of debt contracts and downward nominal wage rigidity. Under optimal policy, default occurs during contractions and is accompanied by large devaluations. The latter inflate away real wages, thereby avoiding massive unemployment. Thus, the Twin Ds phenomenon emerges endogenously as the optimal outcome. In contrast, under fixed exchange rates, optimal default takes place in the context of large involuntary unemployment. Fixed-exchange-rate economies are shown to have ...

Involuntary unemployment and the business cycle

We propose a monetary model in which the unemployed satisfy the official U.S. definition of unemployment: people without jobs who are (1) currently making concrete efforts to find work and (2) willing and able to work. In addition, our model has the property that people searching for jobs are better off if they find a job than if they do not (that is, unemployment is involuntary). We integrate our model of involuntary unemployment into the simple new Keynesian framework with no capital and use the resulting model to discuss the concept of the nonaccelerating inflation rate of unemployment. We ...

Microfoundations of inflation persistence in the New Keynesian Phillips curve

This paper proposes a dynamic stochastic general equilibrium model that endogenously generates inflation persistence. We assume that although firms change prices periodically, they face convex costs that preclude optimal adjustment. In essence, the model assumes that price stickiness arises from both the frequency and size of price adjustments. The model is estimated using Bayesian techniques, and the results strongly support both sources of price stickiness in the U.S. data. In contrast with traditional sticky price models, the framework yields inflation inertia, a delayed effect of monetary ...

The great housing boom of China

China's housing prices have been growing nearly twice as fast as national income in the past decade despite (1) a phenomenal rate of return to capital and (2) an alarmingly high vacancy rate. This paper interprets such a prolonged paradoxical housing boom as a rational bubble that emerges naturally from China's large-scale economic transition, featuring an exceptionally high rate of return to capital driven by massive resource reallocation. Because such primarily resource-reallocation-driven high capital returns are not sustainable in the long run, expectations of high future demand for ...

Comment on Eggertsson, \"What fiscal policy is effective at zero interest rates?\"

Gauti B. Eggertsson's paper (published in NBER Macroeconomics Annual 2010) represents an important contribution to the analysis of fiscal policy in the New Keynesian model when the zero lower bound on the nominal interest rate is binding. The paper accomplishes a great deal. It analyzes two types of taxes on capital and labor, the investment tax credit, a sales tax, and two types of government spending. It deserves to be an important reference on fiscal policy in a binding zero lower bound. In my discussion, I focus on the subset of Eggertsson's results that initially surprised me and that I ...

Liquidity needs in economies with interconnected financial obligations

A model is developed in which firms in a financial system have to settle their debts to each other by using a liquid asset (or money). The question studied is how many firms must have access to this asset from outside the financial system to make sure that all debts within the system are settled. The main result is that these liquidity needs are larger when these firms are more interconnected through their debts, that is, when they borrow from and lend to more firms. Two pecuniary externalities are discussed. One is the result of paying one creditor first rather than another. The second ...

Fiscal stimulus and distortionary taxation

We quantify the fiscal multipliers in response to the American Recovery and Reinvestment Act of 2009. We extend the benchmark Smets-Wouters New Keynesian model (Smets and Wouters, 2007), allowing for credit-constrained households, the zero lower bound, government capital, and distortionary taxation. The posterior yields modestly positive short-run multipliers around 0.52 and modestly negative long-run multipliers around -0.42. The multiplier is sensitive to the fraction of transfers given to credit-constrained households, the duration of the zero lower bound, and the capital. The stimulus ...

DSGE models for monetary policy analysis

Monetary DSGE models are widely used because they fit the data well and can be used to address important monetary policy questions. We provide a selective review of these developments. Policy analysis with DSGE models requires using data to assign numerical values to model parameters. The paper describes and implements Bayesian moment matching and impulse response matching procedures for this purpose.
