Article
Full-text available
The 2008 Global financial crisis and the subsequent European sovereign debt crisis deteriorated banks funding conditions and lead to a substitution effect among bond instruments. We examine the pricing of straight, covered and securitization bonds issued by European banks in the 2000-2016 period, with a particular focus on the effect of sovereign c...
Article
This paper investigates how overlapping ownership affects quality levels, consumer surplus, firms’ profits and welfare when the industry is a vertically differentiated duopoly and quality choice is endogenous. This issue is particularly relevant since recent empirical evidence suggests that overlapping ownership constitutes an important feature of...
Article
Online shopping is growing significantly among rural consumers interested in overcoming product assortment limitations in their local markets. Retailers are taking notice, and some are looking for first-mover-advantage opportunities in rural areas where they see greater potential for growth when compared to saturated urban markets. However, expandi...

Working Paper
Full-text available
In some markets, consumers do not know the attributes of all the products that are available in the market, or the prices at which they are offered. To reduce this uncertainty consumers may, at a cost, gather and process information about the attributes and prices of the different products. The uncertainty that persists at the time of purchase affe...

The objective function of managers in the presence of overlapping shareholding may differ from the traditional own-firm profit maximization, as they may internalize the externalities their strategies impose on other firms. The dominant formulation of the objective function in such cases has, however, been critiqued for yielding counter-intuitive pr...
Article
In this paper we investigate the anti-competitive effects of partial horizontal ownership in a setting where: (i) two cost-asymmetric firms compete à la Cournot; (ii) managers deal with eventual conflicting interests of the different shareholders by maximizing a weighted sum of the two firms’ operating profits; and (iii) weights result from the cor...

Working Paper
Full-text available
Recent years have witnessed an increased interest, by competition agencies, in assessing the competitive effects of partial acquisitions. We propose an empirical structural methodology, which can deal with settings involving all types of owners and ownership rights, to quantify the coordinated effects of partial horizontal acquisitions on different...

Working Paper

Recent years have witnessed an increased interest, by competition agencies, in assessing the competitive effects of partial acquisitions. We propose a generalization of the two most traditional indicators used to screen unilateral anti-competitive effects - the Herfindahl-Hirschman Index and the Gross Upward Price Pressure Index - to partial horizo...

Article
Recent years have witnessed an increased interest, by competition agencies, in assessing the competitive effects of partial acquisitions. We propose an empirical structural methodology to examine quantitatively the unilateral impact of partial horizontal acquisitions. The acquisitions may be direct or indirect, and may or may not correspond to cont...
Working Paper
This paper considers a new method of uncovering demand information from market level data on differentiated products. In particular, we propose a globally consistent continuous-choice demand model with distinct advantages over the models currently in use and describe the econometric techniques for its estimation. The proposed model combines key pro...
Working Paper
The concept of diminishing marginal utility is a cornerstone of economic theory. The consumption of a good typically creates satiation that diminishes the marginal utility of consuming more. Temporal satiation induces consumers to increase their stimulation level by seeking variety and therefore substitute towards other goods (substitutability acro...
Article
Full-text available
The objectives of the research were: i) to assess the in-conversion period as a barrier impeding farms conversion to organic; ii) to assess the potential of conversion-grade markets in removing this barrier; iii) to identify other barriers (drives) along the food chain impeding (easing) farms conversion in mainland Portugal. Results show that the i...
Working Paper
This paper examines market dominance and barriers to competition in financial trading venues. The interaction between competition and economic growth is a well established fact in the literature and recent years have witnessed a strong and ferocious promotion of competition in a large spectrum of markets. The financial trading industry is no except...

Organic farming is booming in Portugal. CAP subsidies are the main reason beyond this boom. Converted farms are still a small proportion of the country's total farms. They are mostly extensive (low input) Mediterranean farms located in the mainland interior and less developed regions. Large farms and highly educated farmers are the ones converting....
Article
In this article, we address three policy questions regarding the Portuguese cable televi- sion industry. First whether the high concentration in the industry has a technological justi…cation. Second what is the level of market power that the cable television …rms exercise? Third, what is the impact on prices and welfare of two acquisitions an- noun...
