Money,growth, and the stability of the steady state under myopic perfect foresight

The stability of a monetary growth model is demonstrated. It differs from the standard two- asset model in the presence of interest bearing government debt, the endogenous determination of the money supply and an investment function that is sensitive to interest rates and disposable income.     

A note on distribution-free tests whether two distributions differ only by a parameter

Summary A conservative distribution-free general procedure is proposed for testing the null hypothesis that two distributions differ at most by the value of a parameter.     

On the efficiency of markets for managers

Summary. This paper examines the efficiency of the outside labor market in inducing optimal managerial behavior in the presence of learning. It shows that the incentives provided by the market can be more efficient than the original analysis of Holmstr?m [6] would suggest. Moreover, under a mild additional assumption, the existence of an -efficient equilibrium can be guaranteed if a manager is patient. This result supports Fama's [4] original idea that the outside labor market can be efficient in disciplining top managers. These results also suggest that the empirically documented low levels of explicit incentives for managers might be due to the presence of implicit incentives provided by the outside market.

Soft Computing Techniques for Querying XBRL Data

Availability of business data is an important aspect of effective financial activities. An easy access to financial information has immense influence on actions and decisions regarding investing, trade and operations of companies and firms. The proposed standard – eXtensible Business Reporting Language (XBRL) – provides a means to create a uniform framework for representing corporate and financial information. XBRL defines an easily interpretable, machine-readable and XML-based data format. Its flexibility allows for representing business data using different languages, as well as following different regulation standards. One of important benefits of XBRL is application of XML-based tools and systems that enable easy preparation, processing and validation of corporate data. It is also possible to use XML-based storage and query systems. In this paper we propose and describe a concept of soft queries. They provide the users with a human-friendly interface for interacting with XBRL data. These queries are equipped with linguistic terms (such as large, medium, small) and linguistic qualifiers (all, mostly). Such queries are able to provide the users with results similar to the results obtained when they analyse data themselves. Linguistic terms and qualifiers are represented as fuzzy sets. Fuzzy-based operations and aggregation operators allow for mimicking a human-like processing of data. The proposed approach is illustrated with queries executed on an XBRL document.
