The Speed of Incorporating Information into Prices

2013

Abstract To determine the speed of adjusting asset prices to the latest market information, investors usually resort to semi-strong form efficiency tests. Semi-strong form efficiency is based on the assumption that stock prices adjust rapidly as a result of new public information. The objective of the event study conducted in this paper was to examine whether new information is incorporated into the share price in a single price change after its public distribution. We analyzed the price behaviour of companies listed under Category I of the Bucharest Stock Exchange around events such interim result announcements between June and November 2012.

CORRELATIONS AMONG FORWARD RETURNS IN THE NORDIC ELECTRICITY MARKET

2009

I analyze empirical correlations of electricity forward returns from the perspective of a random field model that specifies the correlations in terms of the temporal separation between forward maturities. It turns out that temporal separation cannot fully account for the empirical forward return correlations. Specifically, the relation between correlations and temporal separation does not seem to be invariant across segments of the electricity forward market or trading periods.

Measuring investor sentiment in the stock market

2011

Recently, investor sentiment measures have become one of the more widely examined areas in behavioral finance. A number of measures have been developed in the literature without having been fully validated, and therefore leaving in question which measure should be used for empirical exploration. The purpose of this study is to examine the relative performance of a number of popular measures in predicting stock returns and to test the relative efficacy of a hybrid approach. Using a panel of investor sentiment measures, we develop a new measure of sentiment which combines direct and indirect sentiment measures. Our results show that our composite sentiment index affects the returns of stocks …

The Returns to Education in Rwanda

2005

05077; International audience; Based on data from the 1999–2001 Household Living Conditions Survey conducted by the Ministry of Finance and Economic Planning, we estimate wage equations for employees in Rwanda, treating the choice of employment sector as an endogenous process and making separate estimates for workers in the modern and traditional sectors of the economy. The results show that returns to education increase with the level of education, contrary to the pattern typically reported in the literature and that the returns to higher education is particularly high in Rwanda. A noteworthy feature in the results is that the returns to education are quite different across sectors of empl…

Hospital performance: Efficiency or quality? Can we have both with IT?

2015

This paper explores influence of IT investment on hospital efficiency and quality.There is a direct effect of IT investment on service quality in hospitals.There is a moderating effect of quality on operational efficiency in hospitals.There is a U-shaped relationship between IT investments and operational efficiency.IT investments have diminishing returns beyond a certain point. The influence of IT investment on hospital efficiency and quality are of great interest to healthcare executives as well as insurers. Few studies have examined how IT investments influence both efficiency and quality or whether there is an optimal IT investment level that influences both in the desired direction. De…

Paradigmen einer interdisziplinaren Germanistik

2018

Il volume contiene saggi che valutano, dall'ottica di diversi paesi del mondo, dal Brasile, all'India, alla Cina alla Corea, a diffferenti zone europee, l'impatto delle tendenze sempre più evidenti alla interdisicplinarietà nell'epoca della digitalizzazione e della globalizzazione sia per la didattica che per la ricerca. L'attenzione va alle ricadute dei nuovi turns sull'area umanistica e in particolare sulla germanistica.

Sraffa and the problem of returns: a view from the Sraffa archive

2022

About a quarter of a century ago, Carlo Panico and one of the authors of this chapter published a paper on ‘Sraffa, Marshall and the problem of returns’ (EJHET 1994) in which they explored links between Sraffa’s mid-1920s critique of Marshallian economics and the analysis developed some 35 years later in Production of Commodities. The 1994 contribution focused exclusively on Sraffa’s published works since his unpublished manuscripts were not yet freely accessible. With the benefit of hindsight, it may be claimed that Sraffa was a scholar who, during his lifetime, published little but wrote a lot (Kurz, 2008). Hence, when in December 1994 Trinity College Cambridge, UK, opened the Sraffa Arch…

NOTE SUI LIMICOLI SVERNANTI NELLE ZONE UMIDE COSTIERE DELLA PROVINCIA DI TRAPANI

2016

Notes on wintering waders in the coastal humid zones of province of Trapani (Sicily). The coastal wetlands of Trapani still are of great national importance for migratory and wintering waders despite the dramatic reduction occurred in the last hundred years. During this research the author carried out surveys in coastal wetlands from Trapani to Mazara del Vallo, in order to estimate qualitative and accurate quantitative values of wintering waders. The census includes four winters, from 2012-13 to 2015-16 and was carried out in the months of December and January. Noteworthy is the wintering for three consecutive years of the Terek Sandpiper Xenus cinereus, the wintering of Oystercatcher Haem…
