Is the Retail Gasoline Market Local or National?

This paper studies the effect of station density on prices in the retail gasoline market in the Czech Republic. We estimate the impact of the number of competing stations in various driving-distance ranges around each station on prices. We find that station density has a negative effect on prices; the effect decreases with distance and is statistically significant up to six kilometers. This suggests that the retail gasoline market is local rather than national.

Sales forecasting in financial distribution: a comparison of quantitative forecasting methods

This paper deals with the issue of forecastability of sales activities of independent financial advisers (agents). Employing the most common quantitative methods on a diverse sample of timelines from multiple advisory companies, we have found that under most settings, these methods offer sub-par performance with high relative errors and no statistical differences between them. When a more granular approach is applied (reflecting sales unit size), ARIMA and the simple moving average emerge as significantly less accurate. This outcome is true for all sales units regardless of their size, when relative error is concerned. Thus, our analysis confirms the difficult forecastability of financial sales, speaking against the utilisation of more sophisticated forecasting methods, which mostly fail when compared to their much simpler and less costly counterparts.

Adoption of the euro: Why is the Czech approach cautious?

When published, the Czech Euro-area Accession Strategy signalled a rather cautious approach to adopting the euro in comparison to the intentions of other EU acceding countries. The euro adoption was scheduled around 2010 and the ERM II was viewed only as a waiting room. The Czech strategy was attuned to specific features of the Czech economy. Although inflation and nominal interest rates converged to the EMU levels before EU entry, large fiscal deficits and the need for significant fiscal reform did not make it possible to meet the Maastrich criteria soon. Moreover, real convergence was viewed as a priority for the forthcoming years and, consequently, the strategy was aimed at maintaining nominal flexibility in order to cushion consequences of price and wage rigidities during the peak period of the catch-up process.
