We performed an extensive simulation study to compare the relative performance of many price-jump indicators with respect to false positive and false negative probabilities. We simulated twenty different time series specifications with different intraday noise volatility patterns and price-jump...

In this paper we analyze the evolution of firm efficiency in the Czech Republic. Using a large panel of more than 190,000 Czech firm/years we study whether firms fully utilize their resources, how firm efficiency evolves over time, and how firm efficiency is determined by ownership structure. We...

We develop a novel estimator of unreported income, perhaps due to tax evasion, that does not depend on as strict identifying assumptions as previous estimators based on microeconomic data. The standard identifying assumption that the self-employed underreport income whereas wage and salary...

We present a model of bank passivity and regulatory failure. Banks with low equity positions have more incentives to be passive in liquidating bad loans. We show that they tend to hide distress from regulatory authorities and are ready to offer a higher rate of interest in order to attract...

A fundamental question in economics since the 1930s has been whether an administrative price system could simulate the results of perfect competition even without a true market for the means of production. The theoretical possibility of such a system has been known since the introduction of...

Mismeasurement of inflation is likely to be more severe in a transition economy than in a more stable environment. Reasonable estimates of the size of the inflationary bias in the Czech Republic suggest that conventionally reported declines in real output and living standards during the...

The link between informed trading and the bid-ask spread has been the focus of abundant literature and some authors feared that a large amount of informed trading might lead to shutdown of markets. We explore this issue using data from the Czech Republic. Our estimates confirm that the share of...

The rapidly changing environment of the transition may create special problems for calculation of index numbers that require a fixed basket of goods and outlets. Using referent-level data we find that using a fixed-weight Laspeyres Index may overstate inflation rates by approximately 5 percent a...

We analyze a unique dataset to test an empirical model of retail bank fee determinants in five Central European countries. Due to the data structure we can cope with heterogeneity and cross-subsidization by employing a representative fee index instead of using variables associated with...

This study examines the responsiveness of trading volume to a firm's earnings announcements We find that the volume and earnings surprise information generated at the first earnings announcement within an industry help to explain the stock returns of the non-announcing firm. Specifically, it...
