This paper investigates the behavior of short-term real and nominal rates of interest by combining consumption-based and production-based models into a single general equilibrium framework. Based on the theoretical nonlinear relationships that link interest rates to both the marginal rates of...

The profession has been longing for closed-form solutions to consumption functions under uncertainty and borrowing constraints. This paper proposes an analytical approach to solving buffer-stock saving models with both idiosyncratic and aggregate uncertainties. It is shown analytically that an...

This paper proposes a model of international trade with capital accumulation and financial intermediation. This is achieved by embedding the Melitz (2003) model into an incomplete-markets neoclassical framework with an endogenous credit market. The model preserves the analytical tractability of...

We formalize the Keynesian insight that aggregate demand driven by sentiments can generate output fluctuations under rational expectations. When production decisions must be made un- der imperfect information about aggregate demand, optimal decisions based on sentiments can generate stochastic...

This paper develops an analytically tractable Bewley model of money featuring capital and financial intermediation. It is shown that when money is a vital form of liquidity to meet uncertain consumption needs, the welfare costs of inflation can be extremely large. With log utility and parameter...

Financial capital and fixed capital tend to flow in opposite directions between poor and rich countries. Why? What are the implications of such two-way capital flows for global trade imbalances and welfare in the long run? This paper introduces frictions into a standard two- country neoclassical...

We use a general equilibrium finance model that features explicit government purchases of private debts to shed light on some of the principal working mechanisms of the Federal Reserve’s large-scale asset purchases (LSAP) and their macroeconomic effects. Our model predicts that unless private...

We construct a model to capture the Keynesian idea that production and employment decisions are based on expectations of aggregate demand driven by sentiments and that realized demand follows from the production and employment decisions of firms. We cast the Keynesian idea into a simple model...

Most empirical studies based on U.S. data suggest that the fiscal multiplier is less than 1 (e.g., Barro and Redlick, 2011). However, Keynes argued that the multiplier would be the largest when markets have failed to the greatest extent in coordinating economic activities (such as during the...

China’s over 25% aggregate household saving rate is one of the highest in the world. One popular view attributes the high saving rate to fast-rising housing prices in China. However, cross-sectional data do not show a significant relationship between housing prices and household saving rates....
