This paper tests the ability of New Keynesian models to match the data regarding a key channel for monetary transmission: the dynamic interactions between macroeconomic variables and their corresponding expectations. We exploit survey expectations data and adopt a dynamic stochastic general equilibrium (DSGE)-VAR approach to assess the extent and sources of model misspecification. The results point to serious misspecification in the expectations-formation side of the DSGE model. The rational expectations hypothesis is primarily responsible for the model's failure to capture the co-movements between observed macroeconomic expectations and realizations. Alternative models of expectations formation help partially reconcile the New Keynesian model with the data.

Abstract This paper explores the macroeconomic effects of inflation targeting in Thailand. Furthermore, this study uses a nonlinear new Keynesian model under the dynamic stochastic general equilibrium framework with price indexation to analyze the monetary policy under inflation targeting in Thailand. The model is estimated using a Bayesian statistic for the Thai economy. It shows that inflation is more stabilized and inflation persistence has fallen after adopting inflation targeting. The paper also indicates that the Bank of Thailand is more responsive to the deviation of inflation from its target using inflation targeting. The key monetary mechanism exists through changes in the real interest rate which affect aggregate demand. It is worth noting that the larger the inflation targeting rate is, the lower the steady state output from its steady state level given no trend inflation.

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)

Sticky Wages

This paper develops a dynamic stochastic general equilibrium (DSGE) model with sticky prices and sticky wages, in which agents have imperfect information on the stance and direction of monetary policy. Agents respond by using Kalman filtering to unravel persistent and temporary monetary policy changes in order to form optimal forecasts of future policy actions. Our results show that a New Keynesian model with imperfect information and real rigidities can account for several key effects of an expansionary monetary policy shock: the hump-shaped increase in output, the delayed and gradual rise in inflation, and the fall in the nominal interest rate.

Micro Foundations

Recently macroeconomists have moved to a new neo-classical synthesis by integrating Keynesian features like imperfect competition and nominal rigidities with dynamic stochastic general equilibrium model of the Real Business Cycle Theory with micro foundations and rational expectations, [see, for instance, McCallum and Nelson (1999)]. The standard model comprises of a trinity; consumption and inflation adjustment equations with a monetary authority’s reaction function. One of the pillar of the modelinflation adjustment equation, also known as New Keynesian Phillips Curve (NKPC) in the literature, has at least two important features; unlike the traditional Phillips curve the NKPC is forward-looking; and it has been derived from the profit maximising behaviour of the firms in a monopolistically competitive market structure.

Feasible Path

In locally linearized dynamic stochastic rational‐expectations models, I introduce the concepts of feasible paths (paths on which the policy instrument can be expressed as a function of the policymaker's observation set) and implementable paths (paths that can be obtained, in a minimally robust way, as the unique local equilibrium under a policy‐instrument rule consistent with the policymaker's observation set). I show that, for relevant observation sets, the optimal feasible path under monetary policy can be non‐implementable in the new Keynesian model, while constant‐debt feasible paths under tax policy are always implementable in the real business cycle model. The first result sounds a note of caution about one of the main lessons of the new Keynesian literature, namely the importance for central banks to track some key unobserved exogenous rates of interest, while the second result restores to some extent the role of income or labor‐income taxes in safely stabilizing public debt. For any given implementable path, I show how to design arithmetically a policy‐instrument rule consistent with the policymaker's observation set and implementing this path as the robustly unique local equilibrium.

<p>Expectations formation of future output fluctuations as a factor for explaining Costa<br />Rican business cycle is the main subject addressed in this paper. The main contribution<br />of this research is the proposition of an econometric model for estimating the effect that<br />an increase in the next quarter expected real GDP has on current quarterly real GDP level.<br />To this end, a dynamic stochastic general equilibrium model is used as the theoretical<br />base for explaining the nature of the causality relationship between expected output<br />variability and economic fluctuations. Furthermore, a state-space representation of a<br />Rational Expectations (R.E.) model is developed for constructing an expectations updating<br />mechanism which fully characterizes the dynamics of the expected output variability. This<br />investigation concludes that a 1% increase in the next quarter’s expected GDP is predicted<br />to generate, on average, an approximate 0.67% growth on current quarterly GDP (in real<br />terms). From this modeling perspective, the econometric analysis concludes this effect<br />is statistically significant and also identifies other relevant factors for explaining Costa<br />Rican business cycle, such as the forecasts of economics variables that determine output<br />fluctuations throughout time.<br /><br /></p>

Expectations Formation

This paper argues for a careful (re)consideration of the expectations formation process and a more systematic inclusion of real-time expectations through survey data in macroeconomic analyses. While the rational expectations revolution has allowed for great leaps in macroeconomic modeling, the surveyed empirical microevidence appears increasingly at odds with the full-information rational expectation assumption. We explore models of expectation formation that can potentially explain why and how survey data deviate from full-information rational expectations. Using the New Keynesian Phillips curve as an extensive case study, we demonstrate how incorporating survey data on inflation expectations can address a number of otherwise puzzling shortcomings that arise under the assumption of full-information rational expectations.

Output Gaps

Abstract This article develops a New Keynesian model in which the inflation rate depends on the present value of future output gaps and asset prices gaps. The latter follows a price adjustment process. These asset price gaps are driven by ‛asset price gap signal technology’, a measure of exponentially distributed asset price gaps with a signalling mechanism. Within a dynamic stochastic optimisation approach, I identify a policy rule for the central bank in which the asset price gap the difference between the actual asset price at time t to its fundamental value plays a crucial role in determining the nominal rate of interest.

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.
