In a small-scale New-Keynesian model with a hybrid Phillips curve and IS equation, the paper is concerned with an arbitrary frequency of the agents’ synchronized decision making. It investigates the validity of a fundamental methodological precept according to which no substantive prediction...

The paper considers an elementary New-Keynesian three-equations model and contrasts its Bayesian estimation with the results from the method of moments (MM), which seeks to match the model-generated second moments of inflation, output and the interest rate to their empirical counterparts....

This paper estimates a high-frequency New Keynesian Phillips curve via the Generalized Method of Moments. Allowing for higher-than-usual frequencies strongly mitigates the well-known problems of small-sample bias and structural breaks. Applying a daily frequency allows us to obtain estimates for...

In this we investigate the welfare effects of optimal monetary policy measurements within a high-frequency New-Keynesian model i.e. under variation of the period length. Our results indicate that the policy maker faces a higher welfare loss on a higher relative to a lower frequency of the...

In this paper we analyze a hybrid small-scale New-Keynesian model with an arbitrary frequency of the agents' synchronized decision making. We study the impact of various demand and supply shocks on the dynamics of the model variables. We show that the corresponding impulse-response functions of...

In this paper we empirically examine a hybrid New-Keynesian model with heterogeneous bounded rational agents who may adopt an optimistic or pessimistic attitude - so called animal spirits - towards future movements of the output and inflation gap. The model is estimated via the simulated method...

In this paper we empirically examine a heterogeneous bounded rationality version of a hybrid New-Keynesian model. The model is estimated via the simulated method of moments using Euro Area data from 1975Q1 to 2009Q4. It is generally assumed that agents' beliefs display waves of optimism and...

The paper considers an elementary New-Keynesian three equation model and compares its Bayesian estimation to the results from the method of moments (MM), which seeks to match finite set of the model-generated second moments of inflation, output and the interest rate to their empirical...

This paper reviews the literature on how retailers, by their individual behavior or as a group, influence international trade flows, and on how trade affects the structure of the retail industry. After reviewing the evidence, we discuss theoretical contributions set in an oligopolistic,...

With its commitment to double the share of renewables in electricity generation to at least 30% by 2020, the German government has embarked on a costly policy course whose public support remains an open empirical question. Building on ample household survey data, we trace peoples'...
