Frauds can be explained not only in terms of individual willingness to cheat, but may also be driven by opportunities to behave dishonestly. The audit policy should therefore be different for different categories of agents. This paper focuses on the optimal audit policy when there are two...

We examine the contribution of incremental and radical innovations to total factor productivity (TFP) growth at the firm level. The first part of our analysis is dedicated to the determinants of innovation and reveals two different innovation regimes. On the one hand, radical innovations rely...

This paper considers empirical work relating to models of firm dynamics. We show that a hazard regression model for firm exits, with a modification to accommodate age-varying covariate effects, provides an empirical framework accommodating many of the features of interest in studies on firm...

Based on the significance of a Minimum Variance Portfolio (MVP) for the understanding of dollarization equilibria, a significant strand of the debate concerned with the driving forces behind this phenomenon has focused on analyzing the determinants of the relative volatility of inflation...

This paper proposes and applies a method of moments to estimate dynamic decision models with corner solutions. The method extends previous results by Hotz and Miller (1993) and Pakes (1994), and it allows for unobserved state variables affecting both the continuous choice (interior solution) and...

This paper is the first attempt to estimate commercial banks’ efficiency in the Visegrad region before joining the EU and also to consider differences in efficiency across the countries. Employing Data Envelopment Analysis, we analyze which of the banking sectors is the most efficient and...

In many countries the shadow employment has a very high priority among policymakers. A new time series for this component of the labour market has been recently released by the Italian institute of statistics. Taken together they give the motivation and the occasion for a fresh analysis of the...

Our survey of private manufacturing firms finds the size of hidden ‘unofficial’ activity to be much larger in Russia and Ukraine than in Poland, Slovakia and Romania. A comparison of cross-country averages shows that managers in Russia and Ukraine face higher effective tax rates, worse...

The size, growth and causes of the US “underground economy” are examined in light of new estimates of foreign holdings of US currency. World dollarization partially resolves the “currency enigma” which refers to the anomaly that roughly 80% of the US currency supply is “missing” and...

This paper presents new evidence on the dynamics of dollarization and euroization for twenty-five transition countries. Estimates of the amount of foreign currency in circulation (FCC) in transition countries are used to develop a new comprehensive dollarization index (CDI) and separate indices...
