We develop extensions of the variance-ratio statistic for testing the hypothesis a time series is uncorrelated and investigate their finite-sample performance. The tests employ an estimator of the asymptotic covariance matrix of the sample autocorrelations that is consistent under the null for...

A high degree of cyclical synchronization between the new EU member states (NMS) from Central and Eastern Europe and the euro area is generally seen as a prerequisite for successful EMU enlargement. We establish stylized facts on economic linkages between NMS and the euro area using dynamic...

In recent years the computers have shown to be a powerful tool in financial forecasting. Many machine learning techniques have been utilized to predict movements in financial markets. Machine learning classifiers involve extending the past experiences into the future. However the rareness of...

The policies related to regional economic activity developed by European Union (EU) and the role played by regions as economic subject have determined a bigger set of disaggregated statistics at macroeconomic level. The methodologies used nowadays by the Italian national institute of statistics...

The central tenet of inflation targeting is the anchoring of inflation expectations. In this paper, we reexamine the role of key elements of the inflation targeting framework towards this end, in the context of an economy where economic agents have an imperfect understanding of the macroeconomic...

A mutual insurance firm is a firm whose stockholders are the bearers of the insurance contracts. Insurance is then viewed as a collective (pooled) process of persons paying a fixed (or variable, contingent) amount monthly (the premium) and seeking protection against claims that may occur to any...

Precautionary saving has engendered much interest, both because of the possibility that it can explain why, contrary to the basic Lifecycle/Permanent-Income Hypothesis, consumption roughly tracks income over the lifecycle and because of speculation that precautionary saving might account for a...

Parallel particle filters for evaluation of the likelihood of DSGE models are implemented and evaluated in a distributed memory message-passing context. In our paper special emphasis is put on the details of the interprocessor communication which is necessary for load balancing in the particle...

We determine the optimal degree of price inflation volatility when nominal wages are sticky and the government uses state-contingent inflation to finance government spending. We address this question in a well-understood Ramsey model of fiscal and monetary policy, in which the benevolent planner...

Present value calculations require predictions of cash flows both at near and distant future points in time. Such predictions are generally surrounded by considerable uncertainty and may critically depend on assumptions about parameter values as well as the form and stability of the data...
