UNLABELLED The objective of this paper is to verify the hypotheses presented in the literature on the causal relationship between inflation and its uncertainty, for the newest EU countries. To ensure the robustness of the results, in the study four models for inflation uncertainty are estimated in parallel: ARCH (1), GARCH (1,1), EGARCH (1,1,1) and PARCH (1,1,1). The Granger method is used to t...

The European Medicines Agency (EMA) and the Federation of Pharmaceutical Industries and Associations (EFPIA) hosted a workshop on modeling and simulation (M&S).(1) Representatives from industry, academia, and regulatory agencies from Europe and beyond discussed the role of M&S in the development and registration of medicinal products within plenary and breakout sessions (BOS). This manuscript s...

This paper studies an advantage of commitment over discretion when a central bank observes only noisy measures of current inflation and output, in the context of an optimizing model with nominal-price stickiness. Under a commitment regime, if current policy turns out to be too expansionary (contractionary) because of the bank’s information problem, subsequent policies should be slightly contrac...

We analyze a simple strategic model of interaction between central bank and labor union. We assume that the intransparency of the central bank (labor union) induces Knightian uncertainty faced by the labor union (central bank). Knightian uncertainty means that decision makers are unable to make exact probability judgements. It is modelled by Choquet Expected Utility Theory and its recent applic...

This paper analyzes some new tests of the Cagan hyperinflation–money demand model which have several advantages relative to those in the literature. They do not confound specification error with rational bubbles, can be implemented with a linear procedure, and are frequently able to detect periodically collapsing bubbles which have challenged existing tests. After a Monte Carlo analysis, the te...

This paper uses the European Commission’s Consumer Survey to assess whether inflation expectations have converged and whether inflation uncertainty has diminished following the introduction of the Euro in Europe. Consumers’ responses to the survey suggest that inflation expectations depend more on past national inflation rates than on the ECB’s anchor for price stability. The convergence in inf...

This paper describes the chaotic monetary environment of medieval and early modern Europe. The poor quality of the coinage was a result both of problems with the supply of bullion and with deficiencies of monetary policy. The paper examines the supply and demand of bullion and the determinants of bullion flows. It then discusses the economics and politics of debasement. It concludes with a desc...

This paper shows that in a small open economy with downward nominal wage rigidity pegging the nominal exchange rate creates a pecuniary externality. The externality causes unemployment, overborrowing, and depressed consumption. Ramsey optimal capital controls are shown to be prudential in the sense that they tax capital inflows in good times and subsidize external borrowing in bad times. Under ...

This paper uses over two years of weekly scanner data from two small US cities to characterize time and state dependence of grocers’ pricing decisions. In these data, the probability of a nominal adjustment declines with the time since the last price change even after controlling for heterogeneity across store-product cells and replacing sale prices with regular prices. We also detect state dep...
