The present paper concerns with a Godunov-type method for the isentropic polytropic gas subjected to transverse magnetic field in a variable cross-section duct.Typical Riemann solutions are used to build the numerical flux at cell interface. We mainly address and solve numerically two special...

This paper formulates a back of the envelope approach to study the effects of monetary policy on household consumption expenditures. We analyze several transmission mechanisms operating through direct, partial equilibrium channels—intertemporal substitution and net interest rate exposure—and...

The Euler equation model for investment with adjustment costs and variable capital utilization is estimated using aggregate US post-war data with econometric methods that are robust to weak instruments and exploit information in possible structural changes. Various alternative identification...

Most of the empirical literature on consumption behaviour over the last decades has focused on estimating Euler equations. However, there is now consensus that data-related problems make this approach unfruitful, especially for answering policy relevant issues. Alternatively, many papers have...

Time-consistency is a key feature of many important policy problems, such as those relating to optimal fiscal policy and optimal monetary policy. It is also important for private-sector decision-making through mechanisms such as quasi-geometric discounting. These problems are generally solved...

In this paper we consider conditions under which the estimation of a log-linearized Euler equation for consumption yields consistent estimates of the preference parameters. When utility is isoelastic and a sample covering a long time period is available, consistent estimates are obtained from...

We investigate the empirical implications of the investment-based model of asset pricing for the Hansen-Jagannathan and Kozak-Nagel-Santosh discount factors in the linear span of equity returns. Our methodology is based on the equivalence between investment and equity returns implied by the...

We investigate the empirical evidence on the Euler equation models using methods that are robust to weak instruments and structural changes for a set of eight countries. We start with the conventional closed economy model and consider extensions that include habits and hand-to-mouth consumers....

The solution to dynamic portfolio choice models can be formulated in terms of a value function by the Bellman principle of optimality, which reduces the multi-period optimal policy choice problem to a sequence of one-period maximization problems. For two adjacent periods, economists compute the...

This study proposes a novel nonparametric estimation approach to solving asset-pricing models. Our method is robust to misspecification errors and it inherits a closed-form solution that facilitates ease of implementation. By transforming the Euler equation, our estimate is fully identified, and...

This paper formulates a back of the envelope approach to study the effects of monetary policy on household consumption expenditures. We analyze several transmission mechanisms operating through direct, partial equilibrium channels--intertemporal substitution and net interest rate exposure--and...

We formulate a general cointegrated vector autoregressive (CVAR) model that nests both a class of consumption Euler equations and various Keynesian type consumption functions. Using likelihoodbased methods and Norwegian data, we find support for cointegration between consumption, income and...

A large psychology literature argues that decision-makers' forecasts of their future circumstances appear overly influenced by their perception of the new information embedded in their current circumstances. We adopt the diagnostic expectations (DE) paradigm (Bordalo et al., 2018) to capture...

In this paper, we make three substantive contributions:first, we use elicited subjective income expectations to identify the levels of permanent and transitory income shocks in a life-cycle framework; second, we use these shocks to assess whether households' consumption is insulated from them;...

At the zero lower bound, the New Keynesian model predicts that output and inflation collapse to implausibly low levels, and that government spending and forward guidance have implausibly large effects. To resolve these anomalies, we introduce wealth into the utility function; the justification...

The paper presents the welfare cost of inflation in a banking time economy that models exchange credit through a bank production approach. The estimate of welfare cost uses fundamental parameters of utility and production technologies. It is compared to a cash-only economy, and a Lucas (2000)...

The authors solve the IS puzzle for the G7 countries. They find that five of the G7 countries have the expected significant negative relationship between the output gap and the real-rate gap; the time series of the remaining two show material deviation from expected IS-curve behavior. The...

We examine the implications of less powerful forward guidance for optimal policy using a sticky-price model with an effective lower bound (ELB) on nominal interest rates as well as a discounted Euler equation and Phillips curve. When the private-sector agents discount future economic conditions...

The rational addiction model is usually tested by estimating a linear second-order difference Euler equation, which may produce unreliable estimates. We show that a linear first-order difference equation is a better alternative. This empirical specification is appropriate under the reasonable...

Evaluating a new survey dataset of German consumers, we test whether individual consumption plans are formed according to an Euler equation derived from consumption life-cycle models. Estimating several consumption Euler equations, the results are mostly in line with the theory: We find evidence...

We address the issue of estimating the Euler equation for emerging markets. Using panel data for Russian households, we show that accounting for consumer type and income level is crucial. Consumers, who have neither savings nor loans, as well as consumers with low income, face liquidity...
