Endogenous Technology

This paper develops and estimates a new Keynesian (NK) model with endogenous technology. It shows that introducing endogenous technology can solve three important puzzles faced by conventional NK models: the “inflation persistence”, “disinflationary news shock”, and “zero lower bound (ZLB) supply shock” puzzles. First, the observed persistence in inflation is explained without relying on the conventional NK models' additional assumptions, e.g., backward price indexation. Second, it explains the observed disinflationary effect of a news shock. Third, the model avoids the conventional NK models' paradoxical, empirically inconsistent prediction that a negative supply shock is expansionary at the ZLB on interest rates.

Two Equilibria

This paper analyzes the effects of the lower bound for interest rates on the distributions of inflation and interest rates. In a New Keynesian model with a lower bound, two equilibria emerge: policy is mostly unconstrained in the “target equilibrium,” whereas policy is mostly constrained in the “liquidity trap equilibrium.” Using options data on interest rates and inflation, we find forecast densities consistent with the target equilibrium and find no evidence in favor of the liquidity trap equilibrium. The lower bound has a sizable effect on the distribution of interest rates, but its impact on inflation is relatively modest. (JEL E12, E23, E31, E43, E52, G13)

In August 2007, when the first signs emerged of what would come to be the most damaging global financial crisis since the Great Depression, the New Keynesian paradigm was dominant in macroeconomics. Ten years later, tons of ammunition has been fired against modern macroeconomics in general, and against dynamic stochastic general equilibrium models that build on the New Keynesian framework in particular. Those criticisms notwithstanding, the New Keynesian model arguably remains the dominant framework in the classroom, in academic research, and in policy modeling. In fact, one can argue that over the past ten years the scope of New Keynesian economics has kept widening, by encompassing a growing number of phenomena that are analyzed using its basic framework, as well as by addressing some of the criticisms raised against it. The present paper takes stock of the state of New Keynesian economics by reviewing some of its main insights and by providing an overview of some recent developments. In particular, I discuss some recent work on two very active research programs: the implications of the zero lower bound on nominal interest rates and the interaction of monetary policy and household heterogeneity. Finally, I discuss what I view as some of the main shortcomings of the New Keynesian model and possible areas for future research.

Standard Framework

This paper proposes a postcrisis New Keynesian model that incorporates agent heterogeneity in borrowing and lending with a minimum set of assumptions. Unlike the standard framework, this model makes the natural rate of interest endogenous and dependent on macroeconomic policy. The main application is to study optimal monetary policy at the zero lower bound (ZLB). Such policy succeeds in raising the natural rate of interest by creating an environment that speeds up deleveraging and thus endogenously shortens the crisis and the duration of binding ZLB. Inflation should be front-loaded and should overshoot its long-term target during the ZLB episode. (JEL E12, E31, E32, E43, E52)

The Interest Rate

AbstractThis paper integrates a money and credit market into a static approximation of the baseline New Keynesian model based on a money-and-credit-in-the-utility approach, in which real balances and borrowing contribute to the household’s utility. In this framework, the central bank has no direct control over the interest rate on bonds. Instead, the central bank’s instrument variables are the monetary base and the refinancing rate, i. e. the rate at which the central bank provides loans to the banking sector. Our approach gives rise to a credit channel, in which current and expected future interest rates on the bond and loan market directly affect current goods demand. The credit channel amplifies the output effects of isolated monetary disturbances. Taking changes in private (inflation and interest rate) expectations into account, we find that - contrarily to BERNANKE and BLINDER (1988) - the credit channel may also dampen the output effects of monetary disturbances. The expansionary effects of a monetary expansion may be substantially diminished if the monetary disturbance is accompanied by a contractionary credit shock. In a dynamic version of our model, in which expectations are formed endogenously, we find that the credit channel amplifies output responses.

Dynamic Stochastic

Optimal forward guidance is the simple policy of keeping interest rates low for some optimally determined number of periods after the liquidity trap ends and moving to normal-times optimal policy thereafter. I solve for the optimal duration in closed form in a new Keynesian model and show that it is close to fully optimal Ramsey policy. The simple rule “announce a duration of half of the trap’s duration times the disruption” is a good approximation, including in a medium-scale dynamic stochastic general equilibrium (DSGE) model. By anchoring expectations of Delphic agents (who mistake commitment for bad news), the simple rule is also often welfare-preferable to Odyssean commitment. (JEL D84, E12, E43, E52, E56)

Nominal Interest Rates

I compare nominal gross domestic product (GDP) level targeting with strict price level targeting in a small New Keynesian model, with the central bank operating under optimal discretion and facing a zero lower bound on nominal interest rates. I show that, if the economy is only buffeted by purely temporary shocks to inflation, nominal GDP level targeting may be preferable because it requires the burden of the shocks to be shared by prices and output. However, in the presence of persistent supply and demand shocks, strict price level targeting may be superior because it induces greater policy inertia and improves the tradeoffs faced by the central bank. During lower bound episodes, somewhat paradoxically, nominal GDP level targeting leads to larger falls in nominal GDP.

Keynesian Model

This paper analyzes a regime-switching New Keynesian model to understand what happens to the aggregate economy when the nominal interest rate hits the zero lower bound (ZLB). Contrary to the literature, our model predicts that the aggregate demand curve is not always upward sloping when the ZLB binds. Instead, it depends on expectations. If the expected duration of the ZLB is short but consistent with expectations surveys, the AD curve can be downward sloping. In that case, the fiscal multiplier is moderate and supply-side reforms are expansionary. These results complement existing findings in the literature.
