The Slovenian Energy Law, adopted in 1999, has opened the internal market to competition up to 64% of the final consumption. The opening of the internal market to foreign competition is envisaged for 2003. With regard to the methodology of price regulation, the Energy Law introduces the “price-cap” regulation, which aims to give firms incentive for cost reduction. To provide information for...

We propose a class of new robust GMM tests for endogenous structural breaks. The tests are based on supremum, average and exponential functionals derived from robust GMM estimators with bounded influence function. We study the theoretical local robustness properties of the new tests and show that they imply a uniformly bounded asymptotic sensitivity of size and power under general local...

We analyze the empirical predictions arising from settings of ambiguity aversion in intertemporal heterogenous agents economies. We study equilibria for two tractable wealth-homothetic settings of ambiguity aversion in continuous time. Such settings are motivated by a different robust control optimization problem. We show that ambiguity aversion affects optimal portfolio exposures in a way that...

This chapter explores the stock price impact of expirations of lock-up provisions that prevent insiders from selling their shares after the Initial Public Offering (IPO). We examine 172 lock-up expirations of 142 IPOs floated on Germany’s Neuer Markt. We detect significant negative abnormal returns and a 25% increase in trading volume surrounding lock-up expiration. The negative abnormal...

As part of a Distributed Information Retrieval system a description of each remote information resource, archive or repository is usually stored centrally in order to facilitate resource selection. The acquisition of precise resource descriptions is therefore an important phase in Distributed Information Retrieval, as the quality of such representations will impact on selection accuracy, and...

Nella prima parte del lavoro, si propone un’analisi delle opere di dieci grandi economisti (Smith, Ricardo, Mill, Jevons, Walras, Marshall, Keynes, Hicks, Samuelson e Debreu) con una chiave di lettura specifica: la ricerca del vantaggio (o principio economico) come fondamento dell’economia. In particolare, si indaga l’evoluzione nel tempo di concetti economici di base quali la moneta e il...

This thesis sheds light on the communication processes through which experts and decision makers integrate their domain specific knowledge in decision making. Understanding knowledge integration as a communicative process, the study analyzes the communicative challenges that are present when communicating expert knowledge across its disciplinary boundaries and discusses practices to overcome...

The quality of web sites (or more in general interactive applications) may be improved taking into account the activity of usability evaluation, in which the quality for the endusers is defined and established. One of the most serious problems related to usability field is that usability evaluation methods often were not defined to be effectively reused by the people who did not invent them. The...

This paper combines two of the popular approaches used in the trade versus technology debate: the factor content approach and the cost-share regression across manufacturing industries. The resulting method allows to decompose skill upgrading at the industry level into a component attributed to outsourcing and a residual. Surprisingly, computer investment explains the component attributed to...
